Multipurpose type drying device

Abstract

The invention discloses a multipurpose type drying device comprising heat pumps, an air inlet passageway, a heat exchanger unit, an air feeding passageway and material drying bins. The heat exchanger unit comprises heat exchangers. Fresh air inlets of the heat exchangers communicate with the air inlet passageway. Heat source inlets of the heat exchangers communicate with the heat pumps. Heating outlets of the heat exchangers communicate with the air feeding passageway. An outlet of the air feeding passageway is connected with the material drying bins. By means of the multipurpose type drying device, the traditional coal combustion heat supply manner is converted into the heat pump heat supply manner, pollution to the environment is effectively reduced, the multipurpose type drying device is energy-saving and environment-friendly, the traditional heat supply manner is replaced with the multipurpose type drying device, transformation is easy and convenient, and large-scale application and popularization are facilitated. The multipurpose type drying device is suitable for various agricultural products, the utilization rate of the whole device is quite high, the drying effect is good, and compared with traditional multiple drying devices, the overall device cost and the land occupation are reduced.

Description

Technical field [0001] The invention relates to the technical field of drying equipment, in particular to a multi-purpose drying equipment. Background technique [0002] my country is a large grain producer and consumer, with an annual grain output of several hundred million tons. After the grain is harvested in our country, due to climate reasons, the grains will not meet the moisture standard due to time to dry, resulting in mildew and sprouting. The annual loss of grain is as high as 5% of the total grain output. Therefore, it is very important for the drying of grain. Our existing grain drying method generally uses the sun exposure method, which is subject to weather and site factors, and has low efficiency, so it is not suitable for use in high-yield grain production areas such as farms. In these high-yield food production areas, coal-fired drying towers are now commonly used. Because coal-fired drying towers use coal as raw materials, coal is a non-renewable resource, and...
