Novel low-temperature grain dryer

Abstract

The invention relates to a novel low-temperature grain dryer, and belongs to the field of grain drying machinery. In the invention, a drying tower body is internally equipped with hot air pipes and air exhaust pipes, wherein, one hot air pipe is arranged at the center of the drying tower body and the other hot air pipes are uniformly distributed on the inner wall of the drying tower body, and thehot air pipes are internally equipped with heaters; the air exhaust pipes are arranged around the central hot air pipes; the hot air pipes and the air exhaust pipes are equipped with air vents; an air outlet is arranged on the side wall of the top of the drying tower body and is connected with an air outlet cylinder, and an air inlet is arranged on the side wall of the bottom of the drying tower body; a drainer is arranged between the air outlet cylinder and an air inlet cylinder and comprises a main evaporator, a condenser and a compressor, the compressor is respectively connected with the main evaporator and the condenser, the condenser is connected with the main evaporator, and an expansion valve is arranged on a connecting pipeline between the condenser and the main evaporator; the air inlet cylinder is internally equipped with an air blower; and a control box is arranged outside the drainer. The novel low-temperature grain dryer has the advantages of reaching uniform grain dryingeffect, keeping the original quality, preventing environmental pollution, achieving the purposes of energy conservation and environmental protection, improving the grain quality and saving the grain drying cost.

Description

technical field [0001] The invention relates to a grain drying equipment, which belongs to the field of grain drying machinery. Background technique [0002] At present, the grain dryer mainly uses an external boiler to heat and dry the grain in the drying tower. The disadvantage is that the heat loss in the drying process is large, which wastes energy and causes environmental pollution; The grain in the center may be overheated and cause coking, while the grain in the center is not dehydrated due to less heat, resulting in a decrease in grain quality and poor drying effect. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a novel low-temperature grain dryer with low-temperature drying, good effect, energy saving and environmental protection. [0004] The purpose of the present invention is achieved through the following technical solutions: a new type of low-temperature grain dryer, which is provided with a ...
