The present invention generally relates to a method and apparatus for supplying viscoelastic food materials such as steam bean jam bun and bean paste, an extrusion apparatus for bar-like double-layered food materials, and A device for coating a material, wherein the rod-shaped bilayer food material is formed by coating an inner food material with an outer food material. In particular, these inventions relate to food material extrusion apparatuses and devices for coating food ingredients, which can stably provide food ingredients, which are more suitable for concise and high-mix low-volume manufacturing. Do.

Conventionally, an apparatus for supplying food ingredients includes a vane pump for providing external food ingredients and internal food ingredients with a double nozzle for extruding rod-shaped bilayer food materials, and for controlling the vane pumps. Device. The apparatus for coating food materials includes a cutting device for cutting rod-shaped bilayer food materials to form a bilayer food product.

In this prior art a portion of the food material held in the hopper is fed to the vane pump by a screw conveyor. The measuring space defined by the two vanes, the rotor and the casing of the vane pump is filled with the food material supplied, after which the food material is connected to the double nozzle with the outlet of the vane pump. Fed into the side flow path. Since the vanes move along an outer cam disposed in the housing of the vane pump, the front vanes located in front of the metering space enter the rotor, after which the metering space is connected to the outlet side flow path. In addition, as the rotor rotates, the food material is pushed by the rear vanes located at the rear of the metering space and fed to the dual nozzles through the outlet side flow path. The rod-shaped bilayer food material formed by coating the inner food material with the outer food material is continuously extruded from the double nozzle with the inner nozzle and the outer nozzle forming the extrusion port. Thereafter, the rod-shaped bilayer food material is cut by a cutting device disposed under the double nozzle to form a coated food product having a substantially constant weight.

In this prior art, however, the pressure of the food material supplied to the double nozzle by each vane of the vane pump and having viscoelastic properties is based on the properties of the food material, due to the frictional resistance on the flow path from the vane pump to the extrusion port. Higher than the pressure in the metering space. Therefore, when the front vane defining the metering space enters the rotor, and then the metering space is connected with the outlet flow path of the food material supply device, the pressure of the food material in the outlet flow path is reduced to a relatively low pressure in the metering space. It is lowered by the food ingredients which have. Thus, the pressure of the food material at the double nozzle is also temporarily lowered, and then the amount of food material (flow rate) to be extruded is reduced. That is, the rod-shaped bilayer food material vibrates due to a change in the pressure of the food material at the outlet side flow path and the double nozzle during extrusion. In particular, when the food material has many bubbles or has a small flowability, and when the food material is extruded from a narrow extrusion port, the vibration becomes severe. In such a situation, if the rod-shaped bilayer food material is cut by a cutting device driven at a predetermined time period, the weight of the coated food product is dispersed, and their size and appearance vary widely.

In addition, since the front vanes enter the rotor, the protruding height of the front vanes gradually decreases. As a result, the amount of food material supplied to the double nozzle is reduced, and the pressure of the food material is also reduced. If the inlet velocity of the front vanes is not constant, the rod-shaped bilayer food material will vibrate while being extruded from the double nozzle because the pressure of the food material in the outlet flow path changes.

As the feeding device of the food material to the vane pump, there is a screw conveyor described above and a roller for feeding the food material to be described later. These are used in the embodiments of the present invention. When food material is fed to the vane pump using these conveyors, often the metering space is not completely filled with food material. In this case, it is possible to increase the rotational speed of these conveyors and increase the amount of food material to be fed, so that the metering space is completely filled with food material. However, if the rotational speeds of these conveyors are increased, the food ingredients are excessively mixed, and thus their quality is likely to be destroyed. Thus, the rotational speed of these conveyors is limited. As mentioned above, if the metering space is not completely filled with food material, the same problem as described in reference 1 arises, which causes the pressure of the food material in the metering space to be lower than the pressure in the outlet flow path. Because.

In the feeding device of the inner food material and the outer food material, if the food material is fed to the vane pump by the screw conveyor, a problem arises in that the whole food material feeding device becomes larger in size.

In addition, in the case of the production of several kinds of coated food products such as dumplings in small lot production, there is a strong demand for reducing the food ingredients remaining in the apparatus after the production of these products.

In mixed small scale production, when the type of product is changed, the device for supplying the food material must be removed from the device for extruding the food material, and then washed. In order to improve the production efficiency, it is required that the food material supply device can be easily removed and installed in the food extrusion device easily.

The port format of each nozzle for extruding food ingredients can be selected from several formats, such as round, quadrilateral and polygonal. Multiple food ingredients may also be designed to constitute a layered food ingredient.

The cutting device 40 is arranged under the double nozzle 30. The cutting device 40 consists of a plurality of shutters 42 for cutting the rod-shaped bilayer food material WC extruded from the double nozzle 30 and for forming the coated food product WD. For example, a plurality of shutters 42 known by Japanese Patent Nos. 2916515 and 3016246 can be used. In addition, the cutting device 40 moves up and down in synchronization with the movement of the vertical moving table 51 of the linear conveyor device 50 described below.

The linear conveyor apparatus 50 is arranged below the cutting device 40. The vertical movement table 51 can be freely moved up and down by the cam 54 and a link mechanism connected to the control motor M4 for moving the table up and down. The drive roller 52 is connected to the control motor M5 through a series of gears (not shown). The belt 53 wound around a plurality of rollers such as the roller of the vertical movement table 51 and the driving roller 52 moves up and down in accordance with the movement of the vertical movement table 51. The belt 53 supports the bottom surface of the bar bilayer food material WC when the cutting device 40 cuts the bar bilayer food material WC to form a coated food product WD. The drive roller 52 is driven by driving the control motor M5 intermittently, after which the coated food products WD are transferred to the next step by moving the belt 53.

As shown in FIG. 1, the rod-shaped bilayer food material extrusion device 1 has a control device 60. The control device 60 supplies the amount of the external food material WA and the internal food material WB to be supplied, the angular velocity, the angular acceleration, and the rotor 15 and the internal food material of the vane pump 13 for the external food material. A control panel 61 having a control switch for controlling the acceleration start time setting of the rotational speed of the rotor 25 of the vane pump 23 is provided. The control panel also controls the splitting speed of the coated food product WD, the delivery speed by the belt 53 and the stopping of the parts of the rod-shaped double layer food material extrusion device 1. The control device 60 also includes a control device 62 for driving each control motor based on the input data.

As shown in FIG. 3, in order to detect the rotation angle D of the rotor 15, a pulse encoder 65 is connected to the pump drive shaft 19 of the external food material supply device 10. . The drive gear 63 is fixed on the pump drive shaft 19 connected to the rotor 15. In addition, the pulse encoder 65 is fixed to the bracket 66 supported at the support base 3, the driven gear 64 is fixed on the rotary shaft 65a of the pulse encoder 65, and the driven gear ( 64 is coupled to the drive gear 63. The number of teeth of the driven gear 64 is equal to the number of teeth of the drive gear 63. Therefore, since the pulse encoder 65 rotates in synchronization with the rotor 15, the pulse encoder can detect the rotation angle D of the rotor 15.

A method of controlling the rotational speed (same as the angular speed) of the rotor 15 is now described. The position of the vane 16B shown in FIG. 4 is defined as "0" degree as the reference position of the rotor 15. As mentioned above, the position of the vanes 16B is the starting point of the space 13B for the supply of the external food material WA. The position of the vane 16A corresponds to the end point of the curved surface 17D of the cam 17 and corresponds to the start point of the curved surface 17A. In addition, at the position of the vane 16B, the position of the rotary shaft 65A of the pulse encoder 65 is defined as "0" degree as the reference position of the rotary shaft 65A.

5 shows a change in the rotational speed V of the rotor 15. The horizontal scale of FIG. 5 shows the rotation angle D of the rotor 15 rotating in the direction of the arrow R2, and the vertical scale shows the speed V thereof. The spacing of the rotor 15 is defined by the angle formed by the adjacent slits 15A (the same as the angle formed by the adjacent vanes 16A-16F), and the rotor 15 is the angle D1 from the reference position. Rotate at the reference rotational speed V1 at the site of the section defined by. Thereafter, the rotor 15 rotates at a speed V2 higher than the reference speed V1 at the portion of the section defined by the other angle D2. Thereafter, the rotor 15 decreases its speed and rotates at the reference rotational speed V1 at the site of the section defined by another angle D3. This cycle of the rotor 15 is repeated six times during one revolution.

The reference rotational speed V1 and the higher rotational speed V2, the values of the angles D1, D2, D3 can be input using the control panel 61. In addition, as described above, the angles D1, D2, D3 are sensed by the pulse encoder 65, and the data for the angles D1, D2, D3 are transmitted to the control device 62.

Example 1-7

Now, the results of the food dough cutting test for dumplings (kasuga manju), which is the external food material WA, by using the rod-shaped double layer food material extrusion device 1 are described.

In these embodiments, the nozzle 35 for the internal food material of the double nozzles 30 is clogged and a nozzle for the external food material having a nozzle diameter of 38 mm is used. In addition, the reference rotational speed V1 of the rotor 15 is set at one rotation per minute, and the angle D2, which is a part of the section for rotating at a higher rotational speed, is set to 15 degrees. The cutting speed of the rod-shaped bilayer food material by the cutting device 40 is set to 20 times per minute.

In addition to the above conditions, the angle D1 is set to "0", "10", "20" and "30" degrees, and the higher rotational speed V2 is set to 1.05 x V1, 1.1 x V1, 1.2 x V1. . Cutting testing of food ingredients is performed with a combination of these variables. The samples in the test consist of 30 food products that are continuously cut by the cutting device.

Comparative Example 1

In Comparative Example 1, the rotor 15 rotates at the reference rotational speed V1 (equal speed), and other variables are the same as those of Examples 1 to 7. That is, Comparative Example 1 shows a conventional method for cutting rod-shaped bilayer food materials.

Examples 1 to 7 are now compared with Comparative Example 1. Table 1 shows the results of Examples 1 to 7 and Comparative Example 1. This shows the angle D1, the higher speed V2, the maximum weight of the product in grams, the minimum weight of the product in grams and the standard deviation of the weights of the product. If the value of this standard deviation is small, it can be understood that the change in weight is small.

6 (a) is a sequential line graph showing the weight of the product of Example 3 in order. 6 (b) is a sequential line graph showing the weight of the product of Comparative Example 1 in order.

By comparing the standard deviation of the weight of these products, it can be clearly seen that the numerical values of the standard deviations of Examples 2 to 6 are smaller than the values of Comparative Example 1. That is, the change in the weight of the products of Examples 2 to 6 is smaller than that of Comparative Example 1. Comparing Fig. 6 (a) with Fig. 6 (b), it can be clearly seen that the amount of change in the sequential lines in Fig. 6 (a) is smaller than that in Fig. 6 (b). Thus, it can also be seen that the pulsating flow of the external food material WA extruded from the double nozzle 30 of Examples 2 to 6 is smaller than that of Comparative Example 1. Also from these facts, it can be seen from Examples 2 to 6 that the amount of change in the pressure of the external food material WA in the outlet side flow path is smaller than that of Comparative Example 1. Thus, in Examples 2 to 6, the pulsation of the pressure of the external food material WA is reduced.

By comparing Examples 1 and 7 with Examples 2 to 6, it can be clearly seen that the weight of the products of Examples 1 and 7 is approximately equal to the weight of Examples 2 to 6. However, the maximum weight and standard deviation of the weight of the product of Examples 1 to 7 become larger than those of Examples 2 to 6. From these results, it can be clearly seen that the pulsating flow of the external food material WA extruded from the double nozzles 30 of Examples 1 and 7 is greater than Examples 2-6.

For Example 1, since the rotation of the rotor 15 is weighted before the pressure of the external food material WA in the outlet side flow path 11D is reduced, and the amount of food material supplied to the double nozzle is vaporized. It is therefore clearly seen that the pressure in the outlet side flow path is further reduced. From this fact, after the vanes 16A start entering the rotor 15 and before the outlet flow path 11D of the hopper 11 begins to connect with the metering space 13A, the external food material WA is removed. It can be seen that the feed to the double nozzle does not start. In other words, some time is required before the external food material WA is supplied to the double nozzle.

For Example 7, since the pressure of the outer food material WA in the outlet side flow path 11D is temporarily reduced, and then this pressure gradually increases, the rotation of the rotor 15 causes the pressure of the food material to be relatively It is increased at the site of the section that becomes high.

The average weight of the food ingredients of Examples 1 to 7 is greater than that of Comparative Example 1. The reason is that the rotational speed of the rotor 15 increases in the section in which the rotor rotates at a higher rotational speed V2, so that the external food material WA supplied from the vane pump 13 for external food material to the double nozzle 30 (WA). This is because the amount of) increases.

Example 8

Under the same conditions as in Example 3, a sponge cake dough (baking dough) cutting test to be used as the external food material (WA) was performed. The samples in this test consisted of 30 food products that were continuously cut by a cutting device.

Comparative Example 2

For Comparative Example 2, the rotor 15 rotates at the reference rotational speed V1 and the other variables are the same as in Example 8. That is, Comparative Example 2 shows a conventional method for cutting rod-shaped bilayer food materials.

Table 2 shows the results of Example 8 and Comparative Example 2. By comparing the standard deviation of Example 8 with Comparative Example 1, it can be seen that they are the same. That is, the change of the product weight of Example 8 is smaller than the comparative example 2. Thus, for Example 8 it can be clearly seen that the pulsating flow of the rod-shaped food material of the external food material WA extruded from the double nozzle is reduced.

Comparing Figs. 6 (a) and 6 (b) shows that the change in the sequential lines of Fig. 6 (a) is smaller than that of Fig. 6 (b). Thus, it can also be seen that the pulsating flow of the external food material WA extruded from the double nozzle 30 of Examples 2 to 6 is smaller than that of Comparative Example 1. From these facts, it can be seen from Examples 2 to 6 that the pressure change amount of the external food material WA in the outlet side flow path is smaller than that of Comparative Example 1. Thus, in Examples 2 to 6, the pulsation of the pressure of the external food material WA is reduced.

Example 9

Next, the food material for dumplings (Kasu Manju), which is the outer food material WA, and the strained bean jam, which is the inner food material WB, are placed in the hopper of the rod-type double layer food material extrusion device 1. The mounted, then coated food products WD are produced by cutting the rod-shaped bilayer food material WC, which bilayer food material includes an inner food material WB coated with an outer food material WA. It is extruded from the double nozzle 30. For Example 9, a double nozzle 30 having a nozzle 35 for an internal food material and a nozzle 36 for an external food material, each having a nozzle diameter of 36 mm and 37 mm, is used. The reference rotational speed V1 of the rotor 15 is set to one revolution per minute, and the higher rotational speed V2 is set to 1.1 x V1. With respect to the angle of the rotor 15, the angles D1, D2, D3 are set to 10 degrees, 15 degrees and 35 degrees, respectively. The angle D2 defines the section in which the rotor 15 rotates at a higher rotational speed V2. The rotational speed of the rotor 25 of the vane pump 23 disposed in the internal food material feeding device 20 has a predetermined constant value. In addition, the operating speed of the cutting device is set to 20 times per minute. Thereafter 30 samples of the coated food product, which are produced continuously, are selected.

Comparative Example 3

In Comparative Example 3, the rotor 15 rotates at the reference rotational speed V1 and the other variables are the same as in Example 9. That is, Comparative Example 3 shows a conventional method of cutting rod-shaped bilayer food materials.

In addition to Table 2, Table 3 also shows the results of Example 9 and Comparative Example 3. From these results, it is understood that the standard deviation of Example 9 is smaller than that of Comparative Example 3 by comparing the standard deviation of Example 9 with Comparative Example 3. FIG. That is, the change of the product weight of Example 9 is smaller than the comparative example 3. Thus, for Example 9, the pulsation flow of the rod-shaped bilayer food material (WC) extruded from the double nozzle 30 is arranged outside of the rod-shaped bilayer food material extrusion device 1 in the external food material supply device 10. It can be seen that it is reduced by controlling the speed V of the rotor 15 of the vane pump for food material, and that the change in the weight of the product cut by the cutting device is also reduced.

From the results of the examples, it can be seen that the external food material WA is stably supplied to the double nozzle so that a temporary decrease in the pressure of the food material in the outlet side flow path 11D is achieved by controlling the rotational speed V of the rotor 15. Can be. According to the change in the number of vanes, the characteristics of the food material, the amount of food material to be supplied to the double nozzle, and the operation of the rotor 15 can be modified by changing the shape of the cam 17.

Next, a second embodiment of the external food ingredient supply apparatus 10 of the present invention is described based on FIG. Fig. 7 (a) shows a plan view of a partial cross section of the rod-shaped bilayer food material extrusion apparatus 1. Figure 7 (b) shows a view along the B-B line shown in Figure 7 (a). In the second embodiment, the same reference numerals as in the first embodiment are used for the same members as in the first embodiment. The description of the same member as in the first embodiment is omitted.

The rod-shaped bilayer food material extrusion device 1 of the second embodiment is a driven gear that replaces an objective body 67, a photodetector 68, a bracket 69, and a drive gear 63. 64, the pulse encoder 65 and the bracket 66 of the control device 60 of the first embodiment. The object 67 is fixed to the pump drive shaft 19 connected to the rotor 15, so that its rotational position with respect to this drive shaft 19 is freely set. The optical sensor 68 for sensing the object 67 is fixed to the bracket 69 supported at the support base 3. The part 67A which protrudes from the target object 67 is arrange | positioned at the outer periphery at regular intervals, and the outer periphery is divided into 6 parts.

The rotational position of the target object 67 shown in FIG. 7B is the same as that of the vane 16. That is, the position of the target object 67 shown in FIG. 7B becomes the reference position of the rotor 15. When the object 67 rotates at a predetermined angle D1 from the reference position at the reference rotational speed V1, the optical sensor 68 detects the portion 67A protruding from the target object 67, and then the optical sensor 68. The signal generated from is transmitted to the control device 60. The control device 60 controls the control motor M1 so that the rotor 15 rotates at the predetermined higher speed V2. Thereafter, when the rotor 15 rotates at another angle D2, since the optical sensor 68 cannot sense the portion 67A, the control device 60 causes the rotor 15 to rotate at the reference speed V1. The control motor M1 is controlled.

By providing a scale on either the object 67 or the shaft 19 and providing the indication on the other, it is possible to adjust the rotation angle of the object 67 to the rotation angle of the pump drive shaft 19. . For example, the rod-shaped bilayer food material extrusion apparatus 1 having the same conditions as those in FIG. 3 sets the angle of the portion 67A of the target object 67 to 15 degrees and pumps the target object 67. By fixing to the shaft 19, the rotation angle from the reference position of the rotor 15 can be set to 10 degrees.

In the rod-shaped double layer food material extrusion device 1 of the second embodiment, the rotor 15 can be controlled by a control device having a simpler configuration than the first embodiment. In addition, despite the fact that the food materials used in the extrusion apparatus can be in one way or in various ways, the extrusion apparatus 1 of the second embodiment can use these materials if the properties of the food materials are similar. Suitable. In the second embodiment, even if the optical sensor 68 is used as a means for detecting the rotation angle of the target object 67, a limit switch capable of detecting the rotation angle by contacting the target object 67 ) May also be used.

Embodiments of the rod-shaped bilayer food material extrusion apparatus 1 of the present invention have been described above. However, the apparatus is not limited to these embodiments, and various improvements can be made within the scope of the claimed invention. For example, in the above embodiments, even if the rotational speed of the rotor 15 of the external food material supply device 10 is limited, the outlet side by controlling the speed of the rotor 25 of the internal food material supply device 20 is controlled. It is possible to reduce the pressure change of the internal food material WB in the flow path 24B and to block the pulsating flow of the internal food material extruded from the double nozzle 30. In addition, it is possible to block the pulsating flow of the rod-shaped bilayer food material extruded from the double nozzle 30 by controlling the speed of both rotors 15 and 25.

In the above embodiments, the rotational speed of the rotor 15 of the external food material supply device 10 is described as being controlled by using a two-stage speed as shown in FIG. 5, but having a multi-stage speed or nonlinear relationship. It is possible to control this by using different velocities and to block the pulsating flow of the rod-shaped bilayer food material. It is also possible to control the rotational speed of the rotor 25 of the device 20 in the same way.

In addition, in the above embodiment, the cutting device 40 has been described as cutting the rod-shaped bilayer food material WC extruded from the double nozzle 30 to produce a coated food product WD, but to a predetermined length. It is possible to cut the rod-shaped bilayer food material WC extruded from the double nozzle 30 to produce a rod-shaped bilayer food material having a. Since the pulsating flow of the rod bilayer food material extruded from the double nozzle 30 can be blocked, it is possible to reduce the weight change of the divided rod bilayer food material and to produce a food product having a stable configuration.

In addition, instead of double nozzles for plural materials, it is possible to use, for example, flat nozzles for single materials with long thin cross sections.

By the method and apparatus according to the invention, the pulsating flow of the rod bilayer food material continuously extruded from the double nozzles connected to the outlet side flow path and cut off and coated from the rod bilayer food material by the cutting device It is possible to reduce the weight change of.
