Seafood freeze dryer

Seafood and aquatic food are rich in nutrition and different flavors. At present, fish meal and concentrated fish juice made of low value fish and processing waste are important protein feeds. Protein aquatic products made from aquatic animals and plants, such as oil, gum, vitamins, hormones and other products, are chemical and pharmaceutical products with multiple uses.

Aquatic products are important foreign exchange earning products in coastal areas. Traditional processing technologies such as pickling, drying and frozen aquatic products can not completely retain the nutritional value, and it is not convenient to transport and carry. The application of food freeze dryer in freeze-dried seafood and aquatic products has long been favored by developed countries.

Production process and production process of freeze-drying of clam meat: fresh clam → sea water (brine) feeding → selection → cleaning → scalding → shelling → pre freezing → freeze-drying → packaging and storage.

Key points of production process of lyophilizer:

1. Pretreatment

Keep fresh seafood in seawater (or salt water) for 1 day, spit out the sediment, pick out the dead clams and clean them. The blanching water temperature is about 90 ℃, and the blanching time is about 2min, which is limited to most shell openings. After being taken out and cooled slightly, peel the shell, take the clam meat, clean and tidy it, drain the water, and lay it flat in a dry tray with a thickness of about 5mm.

2. Pre freezing

Refrigerate the shelf of the drying bin so that the plate temperature reaches - 15 ℃. At this time, the material tray is sent to the drying bin of the freeze dryer and placed on the shelf for pre freezing. The clam meat is pre frozen by rapid freezing for about 2H.

3. Freeze drying and packaging

The feed temperature was about - 20.7 ℃ and the eutectic point temperature of clam meat was below (- 15 ℃). Close the liquid inlet valve of the drying chamber, only cool the water trap, and make the material temperature reach about - 20 ℃ after 1.5h; Turn on the vacuum pump to evacuate the water trap and drying bin for 5h; Power on to heat the shelf, set the limit temperature of the shelf to 40 ℃, maintain the vacuum degree of the drying chamber at about 12Pa, maintain the vacuum degree of the water trap at 10Pa and the temperature at (- 45 ~ 50) ℃, and desorb and dry for 2h. When the instrument shows that the material temperature is 37.8 ℃, which is close to the set limit temperature of the heating shelf, it can be considered that the drying end point is reached. Open the emptying valve of the drying bin, take out the freeze-dried clam meat, and quickly seal and pack it with plastic bags.

Seafood freeze dryer equipment is applicable to the freeze-drying production of various seafood products. In the freeze-drying process of squid, sea cucumber, abalone, oyster, carp and other aquatic products, the nutritional value and active substances are retained perfectly, the product value-added profit space is huge, and the food freeze dryer has a great market prospect in the application of freeze-dried seafood and aquatic products!
