Equipment for processing food

The invention relates to food at high speed Processing machines in which a vertical drive shaft has knives or blades for processing food in an open-topped, food-containing bowl holds and drives. The shell made during the processing of the Food is closed by a lid, is swiveled to pour out the contents. E.g. a strong drives Motor at the bottom of the bowl turns on the drive shaft, and a mixing knife is over the lid for rotation along the bowl and around the inner surface thereof for removing and returning the food from the side of the tray to the Neighborhood of the food processing knife held for further processing. The knives are removable and interchangeable so that they or other tool shapes can be adapted to the needs just present during processing. Machines of this type are in the process of processing of food are very effective and so fast (many activities are carried out in less than 1 minute), that the actual processing time is only a small part

809850/0793

the entire "turn" time. I. E. one usually needs longer to load and unload the machine than to process the food once it is in the machine. It is therefore desirable to accelerate the loading and the removal activities as much as possible.

Because of the high speed of operation, it is also important that one is able to observe the food closely. When a processing activity is less than a few Minutes, it is not practical to stop operating every 10 or 15 seconds to check the condition of the food to consider. There is thus a need for a practical, substantially continuous weave to prevent the progression of the Observe and monitor food processing. The lids of known machines have been perforated so that one can watch the food through these perforations. However, this allows certain types of food through this openings are thrown out. Transparent lids are probably unknown in machines of this type on the market because of the construction difficulties in forming an effective, transparent dome with a size that is common on such machines, and also because of the look quickly becomes impossible when food is thrown against the lid at the high speed of the processing knives will. After the food has been processed, the lid is open and the tray is used to remove the food is kiopted, the material still on the lid can run on the floor or the user of the machine and drip.

809850/0798

The reversing knife can also be a hazard if the Lid is open and the bowl is tilted. The turning knives on larger machines of this type are grounded by small ones Electric motors are driven when the machine is stopped be brought to a standstill. In the case of small machines, however, the reversing knives are turned by hand, and if the Machine = is aekipnt with the lid open, the hand knife swivels down under the pull of gravity. This happens, as soon as the bowl is tilted and apparently just at the moment when one begins to eat the food to pour out of the bowl. So when the user is busy pouring out the food, vibrates the Urclenk knife against him, soiling and disturbing him.

The features according to the invention address these difficulties overcome in the known machine. The sticking of the food to the lid is easy and quick with one Abolished the lid scraper mounted for rotation in scraper contact with the inner surface of the lid. In the preferred embodiment is the lid scraper on a Extension of the same carrier or support part held, which holds the mixing deflection knife, so that the cover scraper is rotated around the inner surface of the lid when the mixing reversing knife around the inner surface of the bowl of the the food processing machine is rotated. The lid scraper then removes food from the inner surface of the lid and brings it back to the bulk of the food in the bowl and thus contributes to a good and equal

809850/0798

moderate mixing of all food ingredients during the Processing at. At the end of the processing, the lid scraper removes most of the stuck food materials from the lid before opening the lid to minimize subsequent drying. For cleaning the lid scraper is easily moved into or out of position aif the mixing deflector holder extension.

The extension of the support of the mixing knife holder and the drive handle of the mixing reversing knife cooperate and form a counterweight for the knife and the main part of the support beam. When the bowl and lid are tilted to empty the knife does not swing around, when its axis of rotation is shifted from the vertical. The cover scraper is preferably also provided with sufficient frictional force pressed against the lid to act as a brake and to prevent the lid scraper, the mixing knife and freely rotate the mixing diverter knife holder under the influence of gravity as the bowl is tilted for pouring.

In the preferred embodiment, the lid is made of transparent Made of plastic, e.g. B. polycarbonates. This allows you to watch the food in the bowl while it is be processed, and this in a particularly effective manner because the lid scraper keeps the inner surface of the lid free, so that the food is easy to look at.

809850/0798

According to the invention, the need for a seal between the lid and the shell has been eliminated. The right Bracket for the lid and the sealing of the lid against the top of the bowl is made by a unique, new one Lid configuration or shape ensured in which the lid has a flexible middle part and a rigid outer part. The lid itself is held in place by a fixed part of the lid holder stored, e.g. Typically an arm that rests on the food processor on one side of the tray is held and pivoted. If the lid h is moved to the closed position in which it extends all the way over the shell, the arm is opposite to dam attached to the hinge end to apply a constant downward pressure on the lid. Through this the pand of the lid is fixed and sealed against the edge of the shell, and the elastic middle part of the Lid acts like a spring to provide a tolerance in the fit and maintain the pressure securely for a proper seal to obtain. Of course, the lid cannot be too flexible or it does not seal properly. The outer lid part, that extends from and beyond the flexible middle part is therefore made sufficiently rigid to allow the correct one To hold the shape and to transfer the sealing pressure. This property is provided by the fact that the outer part the Has the shape of a ring forming an annular part of a cone extending outwardly and downwardly from the central portion. The central part is made flexible in that it is shaped like a substantially flat disk, and the

809850/0738

Disk is attached to its center by the cover support arm and supported there. This also makes it clear that in addition to tolerance changes in the closed position and in the "presence of the fixed support arm" the combination the flexible central disk and the outer rigid one Cone brings an adaptation to a slight rotation od = r Twisting of the solid arm, which is therefore not exactly horizontal s2in must.

A possible lateral position inaccuracy, lateral misregistration or lack of alignment between the lid and the Top of the shell, which can occur when the lid shifts to one side, is adjusted from an edge up the outer edge of the rigid part of the lid. The edge forms a substantially planar Hing, which lies over the edge of the tray and helps maintain such an effective seal that a separate seal is not necessary. Thus, the present invention makes it possible to provide a very effective and well-sealed, Provide transparent cover without having to clean a separate seal after a single use, and with sufficient Tolerance in order to maintain satisfactory work over a long period of time without critical adjustment. Another structural advantage consists in the fact that as a result of Transparency of the lid it is not necessary to perforate the lid to view the contents of the dish. In order to the lid is not weakened by such perforations, and the integrity and integrity of the seal against the

809850/0798

The top of the shell is retained.

The object of the invention is therefore to create an improved device for processing food with high speed / which has a lid scraper that mounted for rotation in scraper contact with the inner surface of the lid of the device for removing food from the lid and return to the food mass contained in the mixing bowls of the device; at which the Lid can be formed from substantially transparent fabric; in which the lid structure one approach to such transparent material with remarkable tolerance creates while a good seal of the lid against the edge of the bowl is ensured; bsi which a separate seal, e.g. B. ring seal, between the lid and the shell is not necessary is; wherein the lid has a central, flexible part and an outer, rigid part; which a mixing knife holder may have in the lid, including a counterbalance for the mixing knife if its axis of rotation is not vertical is; which can hold the lid scraper on the structure that holds the mixing reversing knife, the lid scraper then acts as a friction brake to prevent free rotation of the mixing knife when its axis of rotation is not vertical; and the foregoing features, purposes and tasks achieved at an adaptable, versatile and durable configuration or design capable of handling a wide variety of food products.

The following are preferred embodiments of the invention described. The device 20 for processing food is shown in Figure 1 and comprises a stand 22 with hollow, vertically extending arms 2 3a and 2 3b. The poor 2 3a and 23b support a shell 25 and a drive motor 26 via shafts 28a and 28b, which are in arms 23a and 23b, respectively are rotatably mounted. The shafts 28a and 28b can thus pivot freely and freely rotate and form in the arms 23a and 23b a horizontal axis of rotation for the scarves 25 and the motor 26. The shafts 28a and 28b are in bores 31 in a motor and received in a neck support strut 32 or spar 33 extending between the arms 23a and 23b. The waves 2 8a and b are pinned by pins 33 in the spar 32 to provide the possibility that the shafts and the spar together as one Rotate unit.

When the tray is in the food processing position it is upright (as in Fig. 2 in dashed lines

809850/0798

Lines ae shows) and open at the top, with its upper edge 34 a horizontal plane forms. The shell 25 is substantially radially symmetrical and forms a figure of revolution around the vertical Center line of the shell. The drive shaft 35 (Figure 11) of the motor 26 enters the shell 25 through its bottom and is coaxial with the center line of the shell. As is clear from Figure 2, the horizontal or pouring axis is which is formed by the corrugations 28a and b, between the center line of the bowl and the frontal or pouring edge of the Sfoale arranged on which a pouring lip 37 is located.

By arranging the horizontal axis at the front, a greater degree of

it
Not molded as would be the case if the axis passed through the centerline of the shell, as in many known machines. The larger pouring height ensures sufficient freedom for conventional receiving pans, such as. B. the pan 38 on the cart 39 according to FIG.

The (not shown) food is in the tray 25 by at least one food processing tool, such as z. B. knife 40 processed, which are carried on a tool or knife mount 42. The attachment 42 is a hollow shaft which fits aif the drive shaft 35 (Figure 11) and has a hollow square coupling 4 3 at its base which in terms of drive, fits on the matching, square drive part 44 on the drive shaft 35 at the bottom of the shell (Fig. 11 and 14). The coupling between the drive shaft and the knife attachment transmits the drive torque from the drive shaft to the attachment and to the knives 40. The huge

809850/0798

Ser fastening 42 extends upward and terminates at one upper end 46 adjacent to the upper end 47 of the drive shaft 35. The knife attachment can easily be removed and thereby be replaced so that it is pushed down vertically onto the drive shaft and from this over its upper end 47.

FIGS. 11 through 13 illustrate details of FIG Hand operated wedge lock for attaching and loosening the knife attachment 42 and the food workers Knife 40 on the drive shaft 35. As shown, the upper end 47 of the drive shaft 35 ends in a cylindrical one Projection or head part 50, the axis of which coincides with the axis of rotation of the drive shaft 35. The lead or the boss 50 thus forms a vertically oriented, cylindrical surface 51. The upper end 46 of the knife attachment 42 is similarly provided with a cylindrical bore 55 with a substantially vertical axis, which however does not coincide with the axis of rotation of the drive shaft 35 and therefore with respect to the cylindrical projection 50 is eccentric. As a result, the vertically oriented, cylindrical surface 56 is on the inside of the bore 55, which is spaced from the surface 51, eccentric with respect to it. Furthermore, as shown, the Surface 51 of protrusion 50 contained in the cylindrical volume formed by surface 56 of bore 55 is. Surfaces 51 and 56 are surfaces of revolution and the space 60 (Figure 11) between them is radial eccentric space. As a result of the symmetries that are a consequence

809850/0798

of shapes, figures and surfaces of rotation (their axes are vertical), the radial is eccentric Space 60 is essentially a symmetrical space around its radial line of symmetry, which is defined by the relevant axes of rotation Surfaces 51 and 56 go. (This can be seen in Figure 13, where the top and bottom halves of the figure are aa horizontal Line of symmetry are symmetrical).

Surfaces 51 and 56, and the radially eccentric space 16 they define, are important parts of the wedge lock by which ground mount 42 is attached to drive shaft 35. The remainder of the wedge nerra is worn in a cap 61 which has a hand-engageable head 62 on its top and a wedge 65 extending from its bottom side. The wedge 65 has an inner cylindrical surface 66 of the same dimension as and is complementary to the cylindrical surface 51 on the protrusion 50, and has an outer surface 67 of the same dimension as the surface 56 within the cylindrical bore 55 on the upper end 46 the knife attachment 42 and is complementary to it. The part 65 is thus dimensioned to be received in the radially eccentric space 60 and essentially complementary to this, on the upper ends 46 and 47 of the attachment 42 and drive shaft 35 is located on the fixture, the operator grasps the cap head 62, adjusts the wedge 65 with respect to the space 60 , and inserts the wedge into the space 60. Next, the cap 61 will be sharp either after

809850/0798

rotated left or right. This is how the surfaces grip

with
66 and 67 / oversize the surfaces 51 and 56 when they move relative to one another and as soon as the wedge is pushed to force its larger parts into the narrower parts of the eccentric space 60. Through this oversize wedge engagement, the knife fastening coupling 4 3 and the drive shaft drive part 44 are blocked in tight engagement with one another in order to secure the fastening 42 and the elements thereon. ichen knife 40 to be attached to the drive shaft 35.

The projection 50 is shown so that its axis with the axis of rotation of the drive shaft 35 coincides, but it is understood that the axis of the Vornrunges 50 and the cylindrical Bore 55 could easily be replaced with a similar one Modification on surfaces 66 and 67 on wedge 65. This would still have an open-topped, radially eccentric space between the upper ends 46 and 47 of the knife attachment 42 and the drive shaft 35 cause. Another analysis makes it clear that the wedge according to the invention does not need surfaces that are opposite to each other (i.e. facing each other) are. The obare end 47 of the drive shaft 35 could, for. B. be provided with a bore (which is not even cylindrical to needs to be), and the outside of the upper end 46 of the knife mount 42 could be provided with a surface (the also need not be cylindrical), which would be eccentric to one another. It is sufficient that the two upper ends 46 and 47 have surfaces which are spaced apart from one another eccentrically, preferably vertical, one

809850/0798

geometrically in the other and both engageable by complementary surfaces on cap 61. With such a design, and when properly spaced, the rotation of the cap will lock the mount and drive shaft together, like that
Eccentricities on the cap surfaces are rotated out of alignment with the eccentric drive shaft and knife mounting surfaces. It goes without saying that the knife attachment and drive shaft can be brought together into blocking engagement anywhere and not just on the shell base. Only an area is required therebetween which is spaced closely enough so that the eccentric surfaces are at the
Can block rotation of the cap together.

The top of the device 20 is closed by a cover which has a lid 70 at its center
is supported by a fixed support arm 71, which is at 72 at
one side of the shell 25 is pivotably articulated. The arm
71 pivots on pivot pin 72 from a lower, closed position (Figure 1) to an upper, open position (shown in phantom in Figure 2). The weight of the cover and arm is in equilibrium with a counterbalancing spring 73 (FIG. 4) which forms part of the pivot 72 and acts between the arm 71 and the shell 25. The end
of the arm 71 is latched by a rotary pawl 76 in the lower position, which is controlled by a handle 77 for gripping the
The end of the arm 71 is rotated next to it. The latch 76 occurs
with the arm 71 in a manner engaged that the arm 71 is firmly pressed down against the lid 70 to the

and seal. For example, in one embodiment, drives the pawl 76 moves the arm 71 4.7625 mm (3/16 inch) below where the decJcel 70 with the edge 34 in the Shell 25 engages.

The lid 70 is preferably made of transparent plastic, so that the user of the machine can view the contents of the closed tray without the lid being perforated got to. Perforations weaken the lid structure so that sealing forces are not evenly transferred to the circumference of the lid, and perforations also allow food to splash out of the tray.

However, such a lid must also be effectively sealed over a wide range of working conditions and uses. That is, when the fit between the cover 70 and the shell edge 34 requires critical adjustment of the pawl 76 it is more expensive to calibrate during manufacture and more frequent adjustment is required in operation. To make these different To meet needs, the cover 70 has a structure that allows it to act like a spring, when the arm 71 is pressed down against the lid by the pawl 76. In particular, the middle part 80 is the lid Shaped as a substantially flat disk and serves as a flexible, spring-like part (like a kind of eardrum). That outer part 81 of the lid surrounds the central, flexible part 80 and extends from this and beyond this. That Part 81 is a ring that slopes down to a

809850/0798

to form an annular part of a cone. Dia geometry this The cone thus inevitably stiffens the part 81, so that it is not bent by the pressure of the arm 71 but this force transfers directly to the outer edge of the lid. By making the middle part 80 of the Dachshund smaller, the spring force or Elasticity can be stiffened in an effective way and vice versa.

The dachshund 70 ends in a rim 85 on the outer edge of the stiff, outer pinges 81. The rim 85 is sized to engage the top edge 34 of the mixing bowl and forms one substantially planar ring which overlies this edge of the tray when the cover is closed. Edge 85 is something larger than necessary to accommodate lateral misregistration to be provided between the cover 7O and the upper side 34 of the disk 25, whereby an additional tolerance is created. The tolerances are actually so great that there is no seal between the lid and the bowl is necessary. It should also be noted that the flexible central disk member 80 has a slight rotation of the support arm 71 will tolerate if for some reason the arm is not precisely parallel to the plane defined by the upper one Edge 34 of the shell is formed.

High speed food processing machines of this type usually have a mixing diverter knife, such as a mixer knife. B. that Knife 95. Such knives or blades are attached and supported over the top of the device for rotation about an axis, which is parallel to the axis of the drive shaft 35. The mixing reversing knife is for rotation along the inner surface the shell and arranged around this surface, and

809850/0 ^ 98

to remove food from the side of the tray and return it to the vicinity of the Food processing knife 40. As shown, the following invention has such a mixing deflection knife 9 5, which is supported on a bracket 96, e.g. B. a carrier made of rustproof. Stole. The Halterunq 9 6 carries cantilevered the knife 9 5 from a P-'central drive shaft 98, the is supported for rotation in the lid support arm 71 and through the middle disc portion 80 of the lid into the interior passes through. A handle or crank assembly 99 is on top of drive shaft 98 or at its outer end for the Rotation of the mixing reversing knife 95 by hand during processing attached to the food located in the device 2O.

The drive shaft 98 can be hollow, as shown in Figure 5, and oban and at the bottom of the same be open to a passage through the center of the lid 70 from the outside of the tray 25 into the interior thereof. This creates a possibility For the introduction of liquids into the mixing bowl directly via the food processing knife 40 and the drive shaft 35 while the engine 26 is in operation. The cap 61 effectively shields the hollow drive shaft 98 against Groceries that could otherwise be thrown out. In addition, since the fluids are introduced through shaft 98, the cap 61 acts like a propeller screw for evenly ejecting the liquids over the food as soon as these are processed. It has been found that better

809850/0798

and more uniform processing results are obtained when liquids are introduced in this way.

A lid scraper 100 is on an extension 104 of the Doctor blade holder carrier 96 for rotation therewith mounted in scraper contact with the inner surface of the lid 70. The cover scraper 100 has a .Scraper blade or Scraping knife 101 and a gripping body 102. The latter is a resilient part, which is dimensioned so that it is on an extension 104 seated with a fit and with frictional engagement on this. In the preferred embodiment extends the extension 104 extends in a direction lying radially opposite the main part 105 of the holder, the deflection mass 95 is attached to the main part 105. Then when the mixing knife 95 around the tray 25 by the handling and As the crank assembly 99 is rotated, the lid scraper blade 101 simultaneously removes the food from the inner surface of the lid and returns this to the food mass in the bowl, so that the food is better and more evenly are processed. Upon completion of processing, the lid scraper blade 101 removes food items from the lid 70 before it is opened to prevent dripping from the lid. If the lid is also transparent, the scraper will do that Clear view by removing food.

The arrangement 99 with handle and crank and the extension 104 of the holder 96 preferably extend in radially opposite directions Directions from the main body 105 of the bracket

809850/0798

which the mixing deflector 95 is suspended. The extension 104 and the handle and crank assembly 99 are sized and arranged so that they one Counterbalance for the mixing deflection knife 95 and the main part T05 of the bracket 96 for the tendency or inclination of the mixing reversing knife 95 for rotation under the pull of gravity to reduce or even switch off when the lid is open and the device 20 for removing the food tipped. In addition, the lid scraper 100 is designed in such a way that it has a sufficient frictional force against the lid is biased so that it acts like a brake. In this way, the cover scraper 100 also helps to prevent the mixing deflecting knife 95 and the bracket 96 rotate freely under the influence of gravity when this axis of rotation is off the vertical is shifted. Because the lid scraper and the lid are in frictional contact are, they are preferably made of compatible materials, such as. B. made of rubber or plastic, to avoid grooves or scoring on the inner surface of the lid.

When the device is tilted, as shown in dashed lines in Figure 2 Lines shown to remove the ingredients or components from the tray 25 withstands the weight of the engine 26 the tilting of the bowl. The motor is therefore in a counterbalance so that the food when the tray is tilted can be poured out more easily and controlled better. Such a counterbalance is contained in the arm 23a and in this enclosed so that it would be exposed to the food outside the machine and vice versa

809850/0798

zu Ilygienez './ ecksn is protected. The counterbalancing spring arrangement 11O is attached to the thrust shaft 28a at the upper end of the arm 23a and works against its stop 112 further down in FIG. 7, FIG. 23a. As seen in Figure 6 (which shows the spring assembly when the shell has been fully tilted), the counterbalancing spring assembly HO is thus operative between arm 23a and shaft 28a to help the shaft rotate in a clockwise direction (such as shown in Figure 6) to provide gear compensation for the motor 26 during tilting. The control of the tray 25 during tipping and pouring is also supported by a brake Π3 with the arm 23b. The brake 113 is actuated by a brake handle 114 to control the rotation of the shaft 28b and hence the shell 25 with respect to the arm 23b.

The counterbalancing spring arrangement 110 has a crank 115 which is fixed on the shaft 28a by a screw 116. A yoke 117 is rotatably hinged at 118 on crank or bracket 115 at the end of the crank opposite shaft 28a. The yoke 117 carries a collar 119 at the yoke end opposite the crank 115 and a pivot pin 118, and a tube 120 is fixed to the yoke and collar and extends therefrom in a downward direction away from the pivot pin 118. A guide rod 122 is received in the tube 120 and slides freely up and down through the tube and the collar 119, but cannot slide downward out of the tube due to a stop mitter 123 resting on the upper end of the rod 122 over on the collar 119

809850/0798

- 3t -

is screwed. In other words, the nut 123 ensures a lower limit of movement for the rod 122.

The lower end of the rod 122 opposite the collar 119 passes through a pillow or pad 125. A pad 125 screwed onto the bottom of the guide rod 122 Stop nut 126 creates a lower limit of movement for pad 125 on rod 122, or vice versa the nut 126 creates an upper limit of movement for the guide points 122 through the pad 125. Otherwise the rod 122 and pad 125 are free to slide relative to each other.

Finally, a spring 130 is on the guide rod 122 in FIG Compression attached between the collar 119 and the pad 125, so that the spring 130 is normally the iblock 125 and the collar 119 spreads apart until they reach the stop nuts 123 and 126. This and the rod 122 hold then the spring 130 is compressed or compressed.

In the operating position within the arm 23a, the cushion 125 rests on the stop 112, which acts as two rods or SfcLfte (Figures 1 and 6) which pass through the arm 23a and the pad 125 in a matching receptacle hang in between. As shown by the arrows in FIG. 6, the Kurbai 115 is in one Position that the yoke 117 and the collar 119 from the cushion moved when the shell 25 is out of its upright position

809850/0798

Position for processing food is rotated to its tilted pouring position and vice versa as soon as the bowl is returned to its upright position from the fully tilted position in Figure 6, the collar approaches the Polstsr 125, the tensile stress on the rod 122 is relieved, the spring 130 is further compressed, and the pressure of the feelers 130 acts between the stop 112 (via the pad 125) and the shaft 28a (via the collar 119, yoke 117 and crank 115). The reduction in the distance between the collar 119 and the Pad 125 frees rod 122 for movement therebetween, and within the limits set by nuts 123 and 126 are set. The pad 125 guides the rod 122 so that it holds the spring 130 thereon. The pad 125 leads the rod 122 also when under the pull of gravity slides down. The counterbalancing spring assembly 110 is thus compact, can be contained entirely in the arm 23a, can be easily inserted into the arm and can (as a result of the rod 122) under Bias can be set.

Set a start switch 132 and a poke switch 133 (Figure 3) the device 20 in operation or switch it off. An operating switch 134 controls either continuous operation (when switch 134 is in the "run" position) or intermittent operation (when switch 134 is in Position "push" - "jog" is located). When switch 134 is in the "jog" or "jog" position, the machine stops 20 as soon as the start switch 132 is released or triggered. In addition to the stop switch 133, the device

809850/0798

by releasing the pawl 71, by chining the shell or be stopped by moving switch 134 to the "jog" position is brought.

FIGS. 15 and 16 illustrate an advantageous food basket 135 which is inserted into the shell 25 can be used to process food in basket 135 quickly and easily. Well-known food baskets are out, however Metal has been made to preferably provide sufficient strength and maintain the shape of the basket. Metals, however, are malleable, and once they are bent or dented it is difficult to restore their original shape To restore shape. This creates difficulties in particular when there are gaps or margins, as is the case here are tight. According to the invention, therefore, baskets 135 are used which are made of flexible, non-deformable plastic are. While the baskets are not strong enough to hold their shape, they are especially tough constant deformation, bending or stretching. Each basket is then shaped so that its outer surface closely matches the inner one Surface of the shell fits. Since the basket is very tight or well adapted to the inside of the shell, the fixed one carries or stores Shell the structure of the basket and leads the basket back into its correct shape adapted to the shell. According to the invention therefore, the food basket 135 does not need to be able to hold itself in the correct shape, and can rather, if it is sized to interact with the shell 25, it will resist wear and tear.

The invention therefore achieves many advantages. The lid is constructed and held in such a way that transparent materials can be used for better and easier viewing of the contents of the foodstuff device, with full tolerances also being provided. The Mischumlenkmesser is counter-balancing and tr ^r IGT a lid scraper to remove food from constitute inner surface of the lid to enhance the uniform processing of the Lebensmittel.Damit the inclination of the cover is reduced to dripping when it is opened and one can observe the content if the lid is transparent. The dakkel scraper also acts as a brake and reduces the likelihood that the mixing diverter knife will move when the lid is opened. Pouring out or removing processed food from the device is made easier by a higher pouring height and a counterbalancing system that is held in a container. The insertion and removal of the food processing knives is simple and quick, with only the cap 61 having to be briefly rotated in either direction to release or unlock or lock or lock the mixing knives on the drive shaft. Ingredients or ingredients can be added during processing through the hollow deflecting knife drive shaft, and ingredients are evenly distributed and processed without splashing back. If the food is to be stored in a separate food basket, a flexible, non-malleable or non-malleable basket can be used to the likelihood
