Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an apparatus for crushing fish paste, and is used in the process of producing fish paste products, particularly in the process of grinding fish meat as the paste.

(Prior art) When producing fish paste products such as kamaboko and chikuwa, frozen surimi (hereinafter referred to as fish meat material) is made into surimi through a surimi process, and for this purpose, the following technology has conventionally been used.

That is, the fish meat material cut into squares is fed to a machine called a silent cutter and cut into fine blocks of, for example, 51 squares, and then the blocks are fed to a crusher called a crown and masticated. Additives such as soybean protein, water, and salt were added to this masticated material, and the material was fed into a machine called a ball cutter, and a vacuum was applied during the sliding process to create a paste material free of air pores.

(Problem to be solved by the invention! 1) The conventional technology described above requires three types of machines or devices: a silent cutter, a crown cutter, and a ball cutter, and each is a batch (non-continuous) type. This process was inefficient and resulted in poor material yield.

Therefore, the present invention improves productivity by continuously processing everything from fish meat materials to surimi, using one device.
In this case, it is an object of the present invention to provide a grinding device for minced fish meat that ensures uniform distribution of additives and, in particular, extraction of salt-soluble proteins that determine the quality of fish paste products.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention takes the following technical means.

That is, the present invention provides an elongated cylindrical barrel 1 equipped with left and right chambers 2 and 3 each having a spectacle-shaped cross section and having a fish material supply port 4 at one end and a surimi discharge port 5 at the other end; a feed section 11; A pair of rotors 9, which are inserted into the left and right chambers 2.3, are connected in the axial direction from the supply port 4 to the discharge port 5, and a kneading blade section 14 consisting of a sending blade 12 and a return blade 13. and a rotor drive means 18 for rotating the rotors 9 and 10 in different directions around their axes and asynchronously, and the blade tip portions 16 and 17 of the crosstalk blade portion 14 are curved in the circumferential direction. Form into shape,
When the diameter of the left and right chambers 2, 3 is D, and the gap between the chamber 2°3 and the wing tip portion 16.17 is δ, δ/D is set to 0.002 to 0.005, and , where D/C is approximately 1, where C is the distance between the rotor axes.

(Function) Additives such as soybean protein, water, salt, etc., along with fish meat materials are introduced from the supply port 4 into the left and right chambers 2.3 of the cylindrical barrel 1.

The input material is kneaded by the feed section 11 and the kneading blade section 14 in a pair of rotors 9 and 10 inserted in the left and right chambers 2 and 3, and is transferred to the discharge port 5 to form a suriburi.

In this process, the pair of rotors 9 and 10 inserted into the left and right chambers 2.3 are moved to the third rotor by the rotor driving means 18.
Since they rotate in different directions and asynchronously as shown by arrow A in the figure, a high exchange of materials, etc. between the left and right chambers 2 and 3 is ensured, and a distribution function is ensured to ensure uniform extraction of salt-soluble proteins by salt. .

Furthermore, since the blade tip portions 16 and 17 of the pair of rotors 9 and 10 have a curved shape in the circumferential direction, there is extremely little shearing effect of dividing the constituent molecules of the fish meat material at the tip portions 16 and 17. This eliminates changes in physical properties and ensures distribution function.

Furthermore, by setting δ/D to 0.002 to 0.005, it is possible to secure the scraping action of the adhering material on the inner walls 2^, 3A of the left and right chambers 2.3, improve the material yield, and improve the material yield. The area that is not distributed is reduced, reducing spots.

Furthermore, since D/C is approximately 1, the dead zone at the boundary between the left and right chambers 2 and 3 is small, thereby suppressing the occurrence of spots.

These ensure uniform extraction and distribution of salt-soluble proteins, allowing continuous production of ground fish meat as a material for chewy and uniform paste products, and improving productivity.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes an elongated cylindrical barrel, which is arranged approximately horizontally, and is provided with left and right chambers 2.3 each having a diameter of about the same diameter as the cross-sectional shape of a pair of glasses. One end has a supply port 4 for introducing fish material and additives such as salt into the chambers 2 and 3, and the other end in the axial direction has a surimi discharge port 5.

Incidentally, the barrel 1 is a cylindrical first to third barrels IA, IB.

The supply port 4 is provided with a hopper 6, and the discharge port 5 is provided with a gate 8 that can be opened and closed with a handle 7.

9.10 is a pair of rotors, and the left and right chambers 2.
The rotors 9 and 10 are inserted into the feed portion 11 and the kneading blade portion 14 consisting of the sending blades 12 and the return blades 13 in the axial direction from the supply port 4 to the discharge port 5. The portion corresponding to the discharge port 5 is formed as a straight portion 15.

In the embodiment, the first zone 12A of the feed blade 12 of the rotor 10 has a left-handed helix of 57° to 58° and a helical angle of 14
The second zone 12B has a left-hand helix of around 60" and a helical angle of 14° to 15.
The first zone 13A of the return blade 13 has a right-handed helix of around 60° and a helical angle of 14° to 15@, and the second zone 13B has a right-handed helix of 70° to 71' and a helical angle of 1.
It is said to be between 4° and 15°. Note that the rotor 9 is different from the rotor 10 only in its twist direction, but its twist angle and helical angle are the same as the corresponding portions of the rotor 10 described above.

The blade chins 16 and 17 of the kneading blades 14 in the rotors 9 and 10 described above have a curved shape with no land in the circumferential direction, as shown in FIG.
The clearance δ between each inner wall 2A, 3A and the blade tip portion 16.17
In relation to the chamber diameter, δ/D is 0.002~
It is set to o, oos.

Furthermore, the relationship between the rotor shaft distance MC of the pair of rotors 9 and 10 and the chamber diameter is such that D/C is approximately 1.

Reference numeral 18 denotes a rotor drive means, which includes gears 20 that mesh with the shaft ends of the rotors 9 and 10 in the gear box 19.
．． 21 is provided, and a Cheno coupling 2 is connected to one rotor 9.
2 and the like, the pair of rotors 9 and 10 are made to rotate in different directions and asynchronously around their axes as shown by arrow A in FIG. 3.

In addition, in the figure, 23 is a refrigerant passage for barrel cooling;
Reference numeral 24 denotes a refrigerant passage formed at the rotor axis, through which refrigerant can be sent via an elbow pipe 25 or the like attached to the end of the rotor axis via a rotary joint 25A. 26 indicates a vent hole.

To explain the operation of the embodiment of the present invention constructed as above, fish meat material and additives such as salt are introduced from the hopper 6 through the supply port 4 into the opposing portions of the left and right chambers 2.3.

The input materials, etc. are transferred to the left in FIG. 1 by the action of the feed section 11.11 of the pair of rotors 9, 10, kneaded while being subjected to the transfer action of the sending blade 12, and then transferred to the return blade 1.
3. At this point, the wires are mixed up while being subjected to the return action by the mixing blade 14 in the chamber W2A, 3A, and the transfer force between the feed part 11 and the sending blade 12 is transferred to the returning blade 1.
Since the force is greater than the returning force of No. 3, the surimi is lifted up and discharged from the discharge port 5.

In this kneading (sanding) action, a pair of rotors 9,
Reference numeral 10 rotates in different directions in the direction of arrow A and asynchronously, thereby increasing the exchange of materials between the left and right chambers 2 and 3 to uniformly distribute the additives. In particular, the extraction and distribution of salt-soluble proteins by salt, which determines the quality of the paste product, is promoted.

Further, since the blade tip portions 16, 17 in the rotors 9, 10 have a curved shape with no land portion in the circumferential direction,
Between the chamber inner walls 2A and 3A, the separation (shearing) effect of materials that cause changes in physical properties is suppressed, and rather, δ/D is reduced to 0.
．． 002 to 0.005, the chamber inner wall 2
It acts to scrape off material etc. adhering to A and 3A, and there is a part that is not distributed, that is, less flame generation, and furthermore, since D/C is approximately 1, there is no dead space between the rotors. The number of zones is reduced, and surimi, which is a chewy and uniform paste product material, is continuously obtained from the outlet 5 by uniformly extracting and distributing salt-soluble proteins.

(Effects of the Invention) The present invention is as described above, and includes a rotor in which a kneading vane section consisting of a feed section, a sending vane, and a return vane is provided in the left and right chambers having a cross-section of spectacles provided in an elongated cylindrical barrel in the axial direction. By inserting a pair, the fish meat material input from the supply port at one end of the chamber can be kneaded and continuously transferred to the discharge port at the other end of the chamber. It can be significantly improved.

Furthermore, the pair of rotors inserted into the left and right chambers are rotated in opposite directions and asynchronously by the rotor driving means, so that the exchange of materials between the left and right chambers is enhanced during the process of lifting up fish materials, etc. Uniform distribution of materials that control the quality of paste products and extraction of proteins can be promoted.

In addition, since the blade tips of the kneading blades in the rotor have a curved shape in the circumferential direction, the breaking action of the material, etc. during the wire raising of the material, etc. is reduced, resulting in less change in physical properties (there is less risk of it), and it is mild. It acts as a line raising effect and ensures reliable distribution and extraction.

Furthermore, the gap δ between the left and right chamber inner walls and the blade tip is such that δ/D is 0.002 to 0.005 with respect to the chamber diameter.
Since it is extremely small, it ensures the scraping action of deposits on the inner wall of the chamber, thereby ensuring uniform distribution and extraction without spots.

Also, the relationship D/C between the chamber diameter and the rotor center distance C
Since this is approximately 1, the dead space between the rotors is small, thereby suppressing the cause of spots.
