Grain dryer with uniform heating and used for processing agricultural products

Abstract

The invention relates to a grain dryer with uniform heating and used for processing agricultural products. The dryer comprises a shell, a controller, a discharging mechanism, two feeding pipes and a plurality of support feed, a stirring mechanism, a screen and a drying mechanism are arranged in the shell, the stirring mechanism comprises a first motor, a turntable, a lifting assembly, a lifting plate and a stirring assembly, the stirring assembly comprises a second motor and two stirring units, the drying mechanism comprises a hot air box, an air inlet pipe, an air outlet pipe, a hot air pipe,a transverse pipe, a rotating assembly and a plurality of spray nozzles, and a fan and electric heating wires are arranged in the hot air box. The grain dryer with uniform heating and used for processing agricultural products generates uniformly-distributed up-flowing hot air flows below the screen through the drying mechanism so as to facilitate the uniform heating of the grain above screen. Inaddition, the stirring mechanism stirs the grain in a vertical direction and a horizontal direction so as to roll the grain, to help hot air contact with the grain fully, to ensure the drying effect,and to improve the practicability of the equipment.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a uniformly heated grain dryer used for processing agricultural products. Background technique [0002] The grain dryer uses a hot air drying box to generate a large amount of hot air in a short period of time. Through high temperature treatment, it can kill insect eggs and completely end the discoloration phenomenon during the drying process. The drying box is made of metal aluminum and aluminum inner wall panels, silica gel Cotton insulation, corrugated color steel plate or aluminum alloy outer wall panel. [0003] During the use of the existing grain dryer, because the hot air is used for drying and heating, the air flow direction of the hot air is fixed, so that the heated position of the grain is fixed, and the position where there is more contact with the hot air is easy to heat the grain and cause it to zoom , where there is less contact with the hot air, the grain i...

Problems solved by technology

[0003] During the use of the existing grain dryer, because the hot air is used for drying and heating, the air flow direction of the hot air is fixed, so that the heated position of the grain is fixed, and the position where there is more contact with the hot air is easy to heat the grain and cause it to zoom , where there is less contact with the hot air, the grain is less heated and the drying effect is limited. Not only that, because the grain is placed in piles inside the equipment, the internal grain is not easy to be heated, and the drying effect is extremely limited due to uneven heating. Reduced utility of existing grain dryers
