[Prior art] The above-mentioned shirimenjiyako, small shrimp, etc. are generally spread out on bamboo mats and dried in the sun, so hair, straw waste, dirt, etc. get mixed in during that time or when they are transported, and these must be removed. It is also necessary to classify the grains according to their size and make the grains of the product uniform.

Conventionally, in order to classify and remove impurities from the chirimenjiyako and small shrimp mentioned above, the materials to be sorted were placed in a sieve and vibrated, and the waste was removed through the sieve and workers manually separated the materials into sizes. It is.

[Problem that the invention seeks to solve]

The conventional method of vibrating a sieve to remove impurities and manually sorting chirimenji, shrimp, etc. is a manual process that requires a large number of workers, is time consuming, and is inefficient. efficient,
In addition, since hair and the like get entangled in the sieve and cannot be removed through the sieve, there is a problem in that it takes time and effort to remove the sieve.
