Take the frozen mash processing as an example. The main process is as follows:
The material selection bar weighs more than 25g and the body color is a gray-yellow live carp, and the gray-brown carp is removed.
The cleaning will concentrate the selected carp into a bucket or a cement pool, allow it to swim freely, and change the water frequently to remove surface dirt and silt in the pot for more than one day.
Rinse the cleaned live squid into a clean basket, rinse with clean water, and wash off the attachments on the squid. At the same time, the surface of the processed squid fillets, cross-section stools, knives, etc. will be washed clean and sterilized with 0.25% bleach solution.

Freezing The frozen plate containing the bismuth pieces is promptly fed into a freezing chamber with a temperature below −25° C., so that the temperature of the center piece of the bracts falls below −15° C. within 24 hours. The use of plate freezer or quick freeze cabinet freezing can greatly speed up the freezing speed, so that the temperature of the cymbal sheet center can reach -15°C within 4-12 hours, thereby effectively improving the product quality. After the sepal is frozen, it is a frozen sepal product.
