Using method of energy-saving environment-friendly air energy shrimp shell drying machine

Abstract

Disclosed is a using method of an energy-saving environment-friendly air energy shrimp shell drying machine. The energy-saving environment-friendly air energy shrimp shell drying machine comprises a heat pump device, a drying box, a belt conveyor, a rotary feeding valve, a rotary discharging valve and a controller; the heat pump device is provided with a hot air drying device and a deodorization device, during use, shrimp shells are fed into the drying box through the rotary feeding valve and the belt conveyor, the hot air generated the hot air drying device is used for heating the dried shrimp shells, the belt conveyor and the rotary discharging valve convey the dried shrimp shells out of the drying box, a moisture condensation groove of the deodorization device and an evaporator are used for condensing odor moisture evaporated by the dried shrimp shells into water drops to be drained, and the odor moisture generated by shrimp shell evaporation is prevented from being drained to the air; the evaporator continuously absorbs heat of evaporation water of the heated shrimp shells in the belt conveyor, a compressor and an expansion valve convey the heat to the condenser, the condenser releases heat to heat air, a draught fan feeds the hot air into the belt conveyor to heat the dried shrimp shells, and drying of the shrimp shells is implemented through the continuous circulation.

Description

technical field [0001] The invention relates to a method of using drying equipment, in particular to a method of using an energy-saving and environment-friendly air energy shrimp shell dryer. Background technique [0002] The production of chitin requires the use of shrimp shells, and the shrimp shells need to be cleaned and dried. At present, the drying process of shrimp shells mainly adopts the method of drying in the sun; the method of drying shrimp shells in the sun is not only affected by the weather, but also has low drying efficiency. Moreover, the drying humidity is difficult to control; an energy-saving and environment-friendly air-energy shrimp shell dryer for drying shrimp shells has become a need for shrimp shell drying and environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a new method of using an energy-saving and environment-friendly air energy shrimp...
