AI Technical Summary
Existing facilities struggle to efficiently process both refrigerated and frozen tuna scraps, as the hardness and friction coefficient of the scraps differ significantly between these states, requiring separate processing facilities and thawing, which is time-consuming and reduces freshness.
A double-shaft rotating blade system that can cut refrigerated scraps and shave frozen scraps, combined with a support column for quantitative conveyance, allowing for adjustable processing rates by varying the rotation speed.
Enables efficient processing of both refrigerated and frozen tuna scraps in a single facility, reducing processing time, maintaining freshness, and minimizing costs and space requirements.

Abstract
Description
Technical Field
[0001] The present invention is a facility for crushing and subdividing tuna scraps (about 500 kg to 1000 kg) solidified in a passing box regardless of freezing or refrigeration in a limited space.
Background Art
[0002] In a factory that collects and processes tuna scraps, there is a facility for crushing the scraps solidified in a passing box. Conventional facilities could handle those in the refrigerated state without problems, but those in the frozen state had to be thawed before processing.
Summary of the Invention
Problems to be Solved by the Invention
[0003] Even for the same scraps, many conditions such as hardness and friction coefficient are different between refrigerated and frozen ones. Therefore, it was difficult to subdivide them with the same facility using the conventional method. Also, thawing to process frozen ones is time-consuming and reduces freshness, and preparing separate processing facilities for refrigerated and frozen ones requires excessive cost and space. The present invention aims to solve the above problems by creating a facility that can handle both refrigerated and frozen ones.
Means for Solving the Problems
[0004] Provide a double-shaft rotating blade that functions to cut for refrigerated ones and shave for frozen ones. Even when operating the crusher under the same conditions, the processing amount per hour is significantly different between refrigerated and frozen ones. Therefore, the support column is given a function of quantitative conveyance, and by adjusting it in combination with the rotation speed, the processing amount is manipulated.

Modes for Carrying Out the Invention
[0006] A crushing blade is provided at a fixed distance from the rotating shaft. As a support column and a feed vane of the blade, plates angled with respect to the rotating shaft are arranged in a spiral shape.
Industrial Applicability
[0007] The characteristic of being able to perform crushing and conveying simultaneously can reduce all of the initial cost, running cost, and occupied space. Although the present invention was devised as a crusher for frozen chips, it can be applied to various uses such as crushing and conveying of solidified powder.
Claims
[Claim 1] This crusher is characterized by having the support pillars of the crusher blades angled and arranged in a spiral, which allows the supplied raw material to be crushed and conveyed in a fixed amount at the same time.
