Description

Description: TECHNICAL FIELD The present invention relates to a device for crushing ground fish meat, which is used in a fish paste product manufacturing process, particularly in a lifting process using fish meat as a sliding body.

(Prior Art) In the production of fish paste products such as kamaboko and chikuwa, frozen surimi (hereinafter referred to as fish meat material) is made into a surimi after undergoing a sliding process. Therefore, conventionally, the following technology was used.

That is, the horn-shaped fish meat material is supplied at an opportunity called a silent cutter and cut into fine blocks of, for example, 5 cm square, and then this block is supplied to a crusher called a crown for mastication, Additives such as soybean protein, water, and salt were added to this masticated material and supplied to a machine called a ball cutter, which was evacuated when it was rubbed to obtain a bladder-free sliding upper body.

(Problems to be Solved by the Invention) In the above-described conventional technique, three types of machines or devices, that is, a silent cutter, a crown, and a ball cutter are required, and furthermore, each is processed in a batch (discontinuous) type. Therefore, it is inefficient and the material yield is poor.

Therefore, the present invention improves productivity by continuously processing from fish meat materials to the upper body with one device,
At that time, it is an object to provide an apparatus for crushing fish meat paste, which ensures uniform distribution of additives, particularly extraction of salt-soluble proteins that determine the quality of fish paste products.

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

That is, according to the present invention, the left and right chambers having a cross-sectional spectacle shape having a fish meat material supply port 4 at one end and a surimi discharge port 5 at the other end.
A slender cylindrical barrel 1 provided with 2, 3; a feed portion 11, and a kneading blade portion 14 including a feed blade 12 and a return blade 13 are axially connected from the supply port 4 to the discharge port 5. And a pair of rotors 9 and 10 formed in the left and right chambers 2 and 3, and a rotor driving means 18 that rotates the rotors 9 and 10 in different directions about their axes and asynchronously rotates. Wing chips 16, 17 in the kneading wing section 14
Is formed in a curved shape in the circumferential direction, the diameter of the left and right chambers 2, 3 is D, and the chambers 2, 3 and the blade tip portions 16, 17 are formed.
When the clearance between and is δ, δ / D is formed to 0.002 to 0.005, and when the distance between rotor shafts is C, D / C is approximately 1
It is characterized in that it is formed.

(Working) Add additives such as soybean protein, water and salt together with the fish meat material from the supply port 4 into the left and right chambers 2 and 3 of the cylindrical barrel 1.

The input is a pair of rotors 9,1 inserted in the left and right chambers 2,3.
It is transferred to the discharge port 5 while being kneaded by the action of the feed section 11 and the kneading blade section 14 at 0, and becomes a sliding upper body.

In this process, the pair of rotors 9 and 10 inserted into the left and right chambers 2 and 3 rotate in different directions and asynchronously as indicated by an arrow A in FIG. The exchange function of the materials and the like between them is enhanced and the distribution function is secured, where the extraction of the salt-soluble protein with the salt is made uniform.

Further, since the blade tip portions 16 and 17 of the pair of rotors 9 and 10 are curved in the circumferential direction, the tip portions 16 and 1
In 7, the shearing action of breaking up the constituent molecules of the fish meat material is extremely small, which eliminates the change in physical properties,
Secure the distribution function.

Further, by setting δ / D to be 0.002 to 0.005, the scraping action of the adhered material on the inner walls 2A and 3A of the left and right chambers 2 and 3 is ensured, and the material yield is improved and the part is not partially distributed. Less and less spots.

Further, since the D / C is set to approximately 1, the dead zone at the boundary between the left and right chambers 2 and 3 is small, which can suppress the generation of spots.

As a result, the uniform extraction and distribution of salt-soluble proteins are ensured, and the fish meat surimi, which is a material for a well-kneaded and uniform kneaded product, is continuously produced to improve the productivity.

Reference numerals 9 and 10 denote a pair of rotors, which are inserted into the left and right chambers 2 and 3, and each of the rotors 9 and 10 has a kneading blade portion 14 including a feed portion 11, a feeding blade 12 and a returning blade 13. Are connected in the axial direction from the supply port 4 to the discharge port 5, and the portion corresponding to the discharge port 5 is formed in the straight portion 15.

In the embodiment, the first zone 12 in the feed blade 12 of the rotor 10 is
A has a left helix of 57 ° to 58 ° and a helix angle of 14 ° to 15 °, and second zone 12B has a helix angle of 1 ° with a left helix of about 60 °.

Is rotating in the opposite direction of arrow A and asynchronously,
Here, the exchange of materials and the like between the left and right chambers 2 and 3 is enhanced, and the additive is uniformly distributed. In particular, the extraction and distribution of salt-soluble proteins by the salt that determines the quality of the paste product is promoted.

In addition, since the blade tip portions 16 and 17 of the rotors 9 and 10 have a curved shape with no land portion in the circumferential direction, the material such as a material that changes physical properties is sheared from the chamber inner walls 2A and 3A. The action is suppressed, rather, by setting δ / D to be 0.002 to 0.005, it acts to scrape off the material and the like adhering to the chamber inner walls 2A and 3A, and here, the part that is not partially distributed, that is, the spot generation is reduced. Moreover, since the D / C is set to approximately 1, the dead zone between the rollers is reduced, and the extraction / distribution of the salt-soluble protein is uniform here, and the surimi, which is a uniform paste product with a good texture, is discharged from the outlet. 5
Will be continuously obtained from.

(Advantages of the Invention) The present invention is as described above, and the kneading blade portion including the feed portion, the feed blade, and the returning blade is axially connected to the left and right chambers having a spectacle-shaped cross section provided in the elongated cylindrical barrel. By inserting a pair of rotors, it is possible to continuously knead the fish meat material fed from the supply port at one end of the chamber to the discharge port at the other end of the chamber. Can be greatly improved.

Further, since the pair of rotors inserted in the left and right chambers are rotated in different directions and asynchronously by the rotor driving means, the alternating current of the materials and the like is increased between the left and right chambers in the process of sliding up the fish meat material and the like. It can promote uniform distribution of materials that control the quality of paste products and extraction of proteins.

In addition, since the blade tip portion of the kneading blade portion of the rotor is formed into a curved shape in the circumferential direction, there is less risk of causing material properties to change during kneading of the material and the like, causing less change in physical properties, and a mild kneading. It is a raising effect and can surely distribute and extract.

Further, since the clearance δ between the inner walls of the left and right chambers and the blade tip portion is δ / D with respect to the chamber diameter D of 0.002 to 0.005, which is extremely small, the scraping action of the adhered matter on the inner wall of the chamber is ensured, and thereby It is possible to secure uniform distribution and extraction.

Further, since the relationship D / C between the chamber diameter D and the rotor shaft distance C is set to approximately 1, the dead space between the rotors is small, which suppresses the cause of unevenness.
