Energy-saving and environment-friendly air energy drying machine for shrimp shells

Abstract

The invention discloses an energy-saving and environment-friendly air energy drying machine for shrimp shells. The drying machine comprises a heat pump device, a drying box, a belt conveyor, a rotary feeding valve, a rotary discharging valve and a controller, wherein the heat pump device is provided with a hot air drying device and a deodorization device; during use, the rotary feeding valve and the belt conveyor are used for conveying the shrimp shells into the drying box, the shrimp shells are heated and dried by hot air generated by the hot air drying device, the belt conveyor and the rotary discharging valve convey the dried shrimp shells out of the drying box, a condensation groove and an evaporator of the deodorization device are used for condensing the smelly steam which is evaporated in the process of drying the shrimp shells into water drops to be discharged, and therefore the evaporated smelly steam of the shrimp shells is prevented from being discharged to the atmosphere, and pollution of the smelly steam to the air is reduced; and the evaporator continuously absorbs heat of the evaporated steam of the heated shrimp shells in the belt conveyor, the heat is conveyed to the condenser through a compressor and an expansion valve, the condenser is used for discharging the heat to heat the air, a fan is used for conveying the heated air into the belt conveyor to heat and dry the shrimp shells, and the steps are repeated to dry the shrimp shells.

Description

technical field [0001] The invention relates to a drying device, in particular to 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 the need for drying shrimp shells 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 brand-new energy-saving and environment-friendly air energy shrimp shell dryer, which is used for drying shrimp sh...
