Abstract

The invention relates to an energy saving device for circularly drying an aquatic product at normal temperature, belonging to the field of aquatic product processing equipment. The energy saving device comprises an air pump, a first control valve, a second control valve, a condenser, a third control valve, a drying chamber, a fourth control valve, an evaporator, a fifth control valve, a plate-type heat exchanger, an air blower, a sixth control valve, a compressor and a heat pump system, wherein the left side of the air pump is sequentially connected with the first control valve, the compressor and the condenser through pipelines to enter the drying chamber; pipelines of the third control valve are arranged between the left side drying chamber and the air pump in parallel; pipelines of the second control valve are arranged on both ends of the first control valve and the compressor in parallel; the right side of the drying chamber is sequentially connected with the evaporator, the fifth control valve and the plate-type heat exchanger through the pipelines to enter the air pump; pipelines of the sixth control valve are arranged between the right side drying chamber and the air pump in parallel; the pipelines arranged in the plate-type heat exchanger are arranged on the pipeline positioned between the drying chamber and the evaporator in parallel.

Description

technical field [0001] The invention relates to an energy-saving device for circulating and drying aquatic products at normal temperature, belonging to the field of aquatic product processing equipment. Background technique [0002] In Zhejiang province alone, there are more than 1 million tons of dried aquatic products every year, and the electricity consumption reaches 400-500 million kWh. Due to the high water content and high protein content of aquatic products, the muscle fibers will gradually shrink and be closely connected during the drying process. Therefore, the traditional hot air drying makes the outer layer of aquatic products crusted, which is not conducive to water evaporation, slow drying speed and huge energy waste (heat The gas is directly discharged into the atmosphere). In addition, if the drying temperature is too high, it will cause fat oxidation and Maillard browning, resulting in bad smell and great damage to heat-sensitive ingredients, which will seri...
