Abstract

The invention discloses a ground source heat pump drying device and belongs to the field of drying devices. The ground source heat pump drying device comprises an evaporator. The output end of the evaporator is connected with the input end of a compressor. The output end of the compressor is connected with the input end of a condenser. The output end of the condenser is connected with the input end of a throttle valve. The output end of the throttle valve is connected with the input end of the evaporator. Loop channels which are communicated are arranged in the condenser and the evaporator respectively in a penetrating mode. Driers are arranged on the loop channels. Air discharging ends of the driers are connected with the input end of the evaporator. Air inlet ends of the driers are connected with the output end of the condenser. The ground source heat pump drying device solves the problem that energy loss is high in the drying process in the prior art, energy loss is low in the drying process, and the device accords with the energy policy of global energy conservation and emission reduction. The device is suitable for drying various kinds of rice.

Description

technical field [0001] The invention relates to a drying device, in particular to a ground source heat pump drying device. Background technique [0002] China's rice output ranks first in the world, with an annual total output of about 190 million tons, accounting for about 40% of the world's total output. With the development of agricultural mechanization in our country, the application of rice drying mechanization is gradually increasing. In the prior art, there is a paddy drying machine whose publication number is: CN2446475, which includes a material barrel, a chassis and a blanking barrel. A fan is installed in the chassis and an air inlet is provided. The chassis and the barrel are connected through a hot air pipe. , the outlet of the hot air pipe is equipped with a high-temperature resistance wire heater, and a thyristor temperature switch is installed on the chassis to adjust the heater. The lower part is the blanking barrel. The disadvantage is that the drying de...
