4. freezing: send the cleaned and processed prawns into quick freezing equipment, such as cold air quick freezing machine orliquid nitrogen quick freezing machineperform quick freezing.
during the quick freezing process, the speed and temperature need to be strictly controlled to quickly reduce the temperature of the prawns to prevent the formation of excessive ice crystals and thereby reduce damage to the texture of the prawns.

throughout the entire processing process, each link needs to be strictly controlled to ensure the hygiene, safety and quality of the product.
in addition, the processing technology may differ due to the actual conditions of different companies, and needs to be adjusted and optimized according to specific circumstances.
