Drying Fish-Western Flag Cold Air Drying Room

Western Flag Cold Air Drying Room

With the improvement of people's living standards and the increase in demand for healthy food, dried fish, as one of the delicacies, has unique flavor and nutrition and is deeply loved by consumers. At present, in the domestic market, in addition to northern regions, consumers in southern regions have also begun to accept this kind of delicacy, and the market prospects are promising.

Dried fish, as it is commonly known, is air-dried. Thread the fish with a rope and hang the fish on the bamboo pole. In addition to requiring a large area for drying, this primitive processing method also has various problems such as being greatly affected by weather, high labor costs, easy to breed flies, and food hygiene cannot be guaranteed, which limits the large-scale industrial production of dried fish.

Air drying is not the same as sun drying. Air-drying has requirements on temperature and humidity and needs to be carried out in a low-temperature and low-humidity environment. The cold-wind drying room simulates the natural air-drying environment in winter to dry the fish.

The cold air drying room is also called a cold air dehydrator. It uses low-temperature and low-humidity air to forcefully circulate in the food room to gradually reduce the moisture content of the food and achieve the purpose of drying. Using the low-temperature heat pump recovery principle, the drying results achieve natural air-drying quality. The cold air dryer forces air at a low temperature of 5-40 degrees to circulate on the surface of the fish. Since the partial pressure of water vapor on the surface of the fish is different from that of the low-temperature and low-humidity air, the water in the fish continues to evaporate and the low-humidity air reaches saturation. It is then dehumidified and heated by the evaporator and becomes dry air. The process cycles repeatedly, and finally the fish becomes dried fish.

Use a cold air drying room to dry fish. The fish can be hung on a trolly and pushed into the drying room, or it can be laid on a drying tray and pushed into the drying room. Drying room specifications are available from 400kg to 2 tons.
