5. Drying: Dry mussel meat by drying or drying. Drying workshop or drying field must meet food hygiene requirements. After drying, the water content of shellfish should be below 30%.
The processing technology for mussel processing units successfully developed by Yantai Seawater Farm includes sizing, rolling, cooking, stripping meat, drying, etc., processing 50 to 60 tons of fresh shellfish each day, improving the work efficiency by 7 times, and it is worth promoting.
6, packaging and storage: The mussels are measured according to user requirements. Storage should be dry and ventilated to prevent return of moisture.
