Heat pump type heat recovery crop efficient drying device

Abstract

The invention discloses a heat pump type heat recovery crop efficient drying device. An insulation enveloper is provided with an air inlet to form an airflow channel with an exhaust hopper; a horn port at the left end of the exhaust hopper is provided with a baffle plate controlled by a sine wave humidity extender to realize automatic control of an output flow of damp and hot air currents; and an outlet at the right end of the exhaust hopper is corresponding to a steam-liquid coexistence coil area of an outer machine to realize moisture emission and efficient recovery circulation of drying heat. The sine wave humidity extender automatically controls the moisture emission flow through a humidity control throttle, so that the acceleration of drying speed is particularly facilitated; a moisture discharge port is aligned to the steam-liquid coexistence coil area of the outer machine, so that the efficient recovery of tail heat is particularly facilitated, and the energy conservation and the effect improvement are realized; a fin coil design of the outer machine particularly facilitates realization of the system tail heat recovery, and meanwhile, a compressor is lower in power consumption; and a long-blade fan impeller is uniform in exhausting, stable in wind power and lower in wind pressure, is suitable for places needing air circulation, and particularly facilitates quick and uniform drying of crops in the insulation enveloper.

Description

technical field [0001] The invention relates to a heat pump type heat recovery efficient drying device for crops. Background technique [0002] In order to prevent mildew and facilitate preservation, it is often necessary to dry fresh crops such as soybeans, wheat, and sorghum. At this stage, there are mainly two types of artificial natural drying and dryer drying. Natural drying is greatly affected by the weather and has low efficiency, which is not conducive to the development of agricultural industrialization; although the existing drying machine can achieve rapid drying, it also discharges a large amount of heat due to the dehumidification, so the energy consumption is high and economical. It's not worth it either. If a crop drying device with low energy consumption and high efficiency can be provided, it will be of great benefit to the development of agricultural industrialization, and can effectively reduce human labor and realize energy saving and emission reduction....
