Intelligent cereal drying device based on solar energy

Abstract

The invention relates to an intelligent cereal drying device based on solar energy. The intelligent cereal drying device consists of four parts of a vacuum pipe type solar energy heat collector, a heat exchanger, a gravity circulation type additional heating stock bin and a controller, wherein the gravity circulation type additional heating stock consists of inner walls, a housing, a spiral lifter, far infrared heating pipes, a blowing machine and a wind pipe; the controller consists of parts of a single-chip microcomputer, a temperature-detecting control circuit, a humidity detecting controlcircuit, a solar energy heat collector heat exchanging valve switching circuit, a keyboard and LCD display circuit, a pressure sensor and a circuit thereof, an alarm circuit, a far infrared compensating heater and a heating pipe piston valve; and the humidity detecting control circuit comprises a moisture-sensitive sensor; and the moisture-sensitive sensor is a zirconia moisture-sensitive sensor based on doping of metal ions.

Description

technical field [0001] The invention relates to the field of agricultural machinery and automation, in particular to an intelligent grain drying device based on solar energy. Background technique [0002] Grain drying is a key joint in the process of grain production, and it is also an important part of realizing the full automation of grain production. [0003] The main problems in the grain drying process are insufficient drying capacity, complex drying machinery, backward drying technology, no professional manufacturer, low degree of generalization, standardization, and serialization, and high unit energy consumption. There are problems such as small quantity, low level of drying mechanization, poor manufacturing quality, many models and miscellaneous types, low level of automatic control, heat source pollution and high manufacturing cost. Contents of the invention [0004] The present invention aims to provide an intelligent grain drying device based on solar energy t...
