Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an apparatus for crushing, stirring, and crushing surimi, etc., which is mainly used in the manufacturing process of fish paste products.

Conventional technology For example, fish paste products such as kamaboko, chikuwa, hanpen, and kaniashikaze kamaboko are made from fish meat obtained by harvesting raw fish using a meat-cutting machine, exposing it to water, and dehydrating it. After this fish meat is crushed, stirred, and crushed, each product is given a unique shape and flavor, and then heated in an appropriate method to make the product.

Currently, the grinding of fish meat in the above process is done by first pulverizing the frozen surimi using a cutter, then exposing it to water to dehydrate it, leaving the unfrozen fish as it is, and placing it in a mortar on a bowl. It is generally carried out using a crusher combined with a shaped pestle.

Problems to be Solved by the Invention In the conventional grinding machine, finely minced fish meat or raw fish meat that has been exposed to water and dehydrated is placed in a rotating mortar, and the pestle rotates in the opposite direction of the mortar. It is designed to stir and crush the raw material for the paste inside the mortar.

However, such conventional grinding machines not only have problems in terms of work efficiency, but also the surface of the Surimi inside the bowl-shaped mortar remains exposed to the atmosphere during the grinding process, making it difficult to work in the workplace. Sanitary control of the whole dish is difficult, and in order to prevent fish meat from slithering (a phenomenon in which fish meat gels and loses fluidity), it is necessary to lower the temperature of the fish meat during mashing. It has many problems such as being very difficult to maintain.

The present invention provides a crushing, stirring, and crushing device that can solve the conventional problems as described above.

Means for Solving the Problems The present invention provides a mortar body having a circumferential surface such as a cylindrical shape, a truncated cone shape, a dish shape, a barrel shape, etc., which is installed with its center line facing sideways or slightly inclined. A material input port and a material discharge port are provided at the upper and lower parts of the mortar, respectively, which are controlled to open and close by lids, and one side wall of the mortar is constructed with a door that can be opened and closed. A rotary shaft for scraping whose center line coincides is provided so as to be rotatable, and as the rotary shaft for scraping rotates, the material attached to at least the inner surface of the circumferential surface of the mortar is attached to the rotary shaft for scraping. A scraping member for scraping and agitating and mixing the material inside the mortar is attached, and a plurality of rotary shafts for mashing are attached so that the mashing member consisting of a cutter can be replaced. The rotary shaft for crushing is rotatably mounted and supported on the side wall surface opposite to the provided door in a state below the center line of the mortar body and parallel to or inclined at a predetermined angle with respect to the center line of the mortar body, The material is cut and crushed by the blade of the cutter by rotating the rotary shaft for crushing in one direction, and the material is crushed by the thick back of the cutter by rotating in the other direction. It is.

Function In the above process, after putting the materials, auxiliary materials, additives, etc. as necessary into the mortar through the material input port, and sealing the material input port with a lid, the scraping rotating shaft is rotated to a depth of about 20 to 100 IPm, for example. When the rotary shaft for mashing is rotated at a high rotational speed and at the same time, the scraping member rotates as the rotary shaft for scraping rotates, scraping off the material attached to the inner circumferential surface of the mould. The material in the mortar is stirred and mixed, and the material being stirred and mixed as described above is cut and crushed by the blade of the cutter by the high-speed rotation of the crushing rotary shaft in one direction, and the material is cut and crushed in the other direction. The material is crushed by hitting it strongly with the thick back of the cutter at high speed rotation, and by appropriately combining the rotational directions of the plurality of rotary shafts for crushing, the material can be stirred, mixed, and mixed in an extremely short time. Cutting, crushing, and crushing are completed in a sealed space, and then the discharge port lid is opened and the processed materials are discharged and collected from the discharge port by the rotation of both rotating shafts. The door forming the side wall of the machine can be opened to thoroughly clean the interior in a sanitary manner and prepare for the next work.
