Grain drying machine

Abstract

The invention discloses a grain drying machine comprising a mixing barrel, a conveying device and a drying barrel. The mixing barrel is connected to the conveying device, the conveying device is connected to the drying barrel, the drying barrel is connected to a fan through an air duct, the fan is connected to a hot air furnace through a pipeline, and the fan is connected to the mixing barrel through an air duct. When the grain drying machine is used, a sieve plate reciprocates left and right to screen grains, the crushed stone particles doped in the grains are removed, the quality of the grains is improved, and the condition that the crushed stone particles enter the conveying device, a conveying shaft and a conveying paddle are in friction, and the conveying paddle is damaged can be prevented; the grains are heated by a heating plate, the air duct sends hot air to the drying barrel, the grains are dried, the heating plate effectively reduces the falling speed of the grains, secondarydrying is carried out, and grain drying is more sufficient; the circulating air duct is arranged in the drying barrel, waste heat is used repeatedly, and the energy is saved effectively; and a heat insulating shell reduces heat dissipation in the grain conveying process, and the heat loss is reduced.

Description

Technical field [0001] The invention relates to the technical field of dryers, in particular to a grain dryer. Background technique [0002] The grain dryer refers to a hot air drying box, which uses a rotary heating device to generate a large amount of hot air in a short time. It can kill insect eggs through high temperature treatment and completely solve the problem of grain drying. With the improvement of grain types, the increase in yield and the increase in the state's investment in grain drying equipment, more and more large, medium and small grain drying facilities are being built. Whether it is possible to choose a dryer with high quality, long service life, economical and practical, good reliability and high degree of automation is very important. [0003] Grain will be mixed with some impurities such as crushed stone during the production process. If it is directly conveyed and dried, the crushed stone will impact the equipment and cause the internal wear of the equipmen...

AI Technical Summary

Problems solved by technology

[0003] Grain will be mixed with some impurities such as gravel during the production process. If it is directly conveyed and dried, the impact of the gravel on the inside of the equipment will cause internal wear of the equipment, and the hot air in the drying process will not be effectively used.
