Air energy dryer for grain drying

Abstract

The invention discloses an air energy dryer for grain drying. According to the air energy dryer for grain drying, through cooperative use of a first rotating column, a second rotating column, a connecting plate and a drying plate, when hot air rises from an air guide base, grain at different positions on the drying plate can be heated by different degrees of hot air, so that the drying efficiencyof the grain is improved, and the problem that the drying efficiency is low due to uneven heating of grain at different positions in the prior art is solved; through matched use of vibration blocks, connecting columns, clamping plates and heat conducting plates, the grain jump slightly on the drying plate through vibration, so that the heating efficiency between the grain can be improved, and theproblem of uneven drying, caused by static drying of the grains, between the grain in the prior scheme can be solved; and the hot air can effectively and evenly move in a drying box through matched use of an air inlet pipe, an exhaust pipe, the air guide seat and a flow guide plate, and the problem that the hot air in the drying box is uneven in motion in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of air energy dryers, in particular to an air energy dryer used for grain drying. Background technique [0002] The air energy heat pump dryer is a new type of drying device, which can realize closed cycle drying of low temperature air, and the drying quality of materials is good. By controlling the working conditions of the device, the temperature of the hot dry air in the drying room is between 20 and 80 °C , which can meet the high-quality drying requirements of most heat-sensitive materials; the closed circulation of the drying medium can avoid the impurity pollution that may be caused by the exchange with the outside gas, which is especially important for food, medicine or biological products. In addition, when the material is sensitive to oxygen in the air, an inert medium can be used instead of air as the drying medium to achieve anaerobic drying. The existing air energy dryer is also used for grain d...

Problems solved by technology

[0007] In other aspects disclosed in the embodiments of the present invention, the air intake pipe, the exhaust pipe, the air guide seat and the deflector are used together to discharge hot air into the air guide seat through the intake pipe, and the hot air fills the air guide seat and passes through the air guide seat. The movement of the deflector from the bottom to the top can effectively move the hot air evenly in the drying box, which solves the problem that the hot air enters from the side of the drying box in the existing solution, resulting in uneven movement of the hot air in the drying box question
