- Processed Seafood and Processing Plants in China
Partner Plant in China
Daiichi has several partner processing plants in China. This is the main factory where Daiichi products are processed.
The plant is located in the city of Weihai in Shandong Province of China. Surrounded by sea on three sides, Weihai has long been a flourishing seafood processing area.
The plant is relatively new, having been set up as a joint venture between China and Japan in 2010.
The plant occupies premises of some 24,000 m2 and has 110 employees. It mainly produces frozen seafood such as mackerel and caplin (shishamo) for export to Japan. It is a HACCP certified plant managed by Japanese staff.
Mackerel Fillet Production
① Defrosting
Defrosting mackerel: In order to maintain freshness, the fish is partially defrosted to the optimal level for processing.
② Preparation
Removal of head/tail and gutting: Mackerel is processed in quick succession while half-frozen.
③ Filleting
Filleting mackerel: The fish is filleted swiftly.
④ Freezing
Freezing mackerel fillets: The filleted mackerel is placed on a freezer conveyor and put through a -45°C tunnel freezer.
⑤ Finishing
Freezing completed: 45 minutes after going into the freezer, even the highly oily north European mackerel comes out rigidly frozen.
⑥ Sorting
Final sorting of frozen mackerel: The frozen mackerel fillets are sorted by size and packed into cartons.
Processed Caplin Production
① Sorting
Sorting caplin: After defrosting, the fish is sorted into male and female.
② Brining
Brining caplin: The fish is soaked in cooled brine and salted.
③ Skewering
Skewering caplin: Skewers are inserted from the gills and out through the mouth; several caplin are put onto one skewer.
④ Drying
Drying caplin: The fish is dried on the skewers for a regulated time and at temperatures between 20°C and 23°C all year round.
⑤ Freezing
Freezing caplin: Still on the skewers, the fish is frozen using an air blast freezer.
⑥ Packing
Packing caplin: Caplin is a small fish and as product temperature is prone to rise easily, it is packed swiftly into boxes in a special chilled room with temperature control set at below 4°C.
