Efficient grain drying machine with low breakage rate

Abstract

The invention provides an efficient grain drying machine low in breakage rate, belongs to the technical field of grain storage, and aims at solving the technical problems that an existing grain drying machine is low in drying efficiency and high in breakage rate. Comprising a material barrel, a feeding mechanism is arranged at the lower end of the material barrel, a mounting box is connected to the upper end of the material barrel, an air inlet pipe is fixed to one side of the mounting box, a spiral slide way is connected to the other side of the mounting box, a discharging mechanism is arranged at one end of the spiral slide way, a dispersing mechanism is arranged in the spiral slide way, and spiral blades are rotationally arranged in the material barrel; the contact time and the contact area of grains and hot air are increased, the drying efficiency is improved, the repeated drying frequency is reduced, and the breakage rate is reduced; an operator can add grains into the annular hopper from all directions, so that the action is more convenient; hot air is separated from the dried grains, so that the equipment safety is improved; and residual heat of hot air is used for heating grains in the material barrel, energy recovery is achieved, and the drying effect is improved.

Description

technical field [0001] The invention belongs to the technical field of grain storage, and relates to a grain dryer, in particular to a high-efficiency grain dryer with low breakage rate. Background technique [0002] Grain dryer is an assembly of dryers, which is a general name for various equipment of grain dryers, and can also be called grain dryers, such as corn dryers, paddy dryers, rice dryers, Wine lees dryer, etc., we can all call it a grain dryer; [0003] Before the grain is stored, a dryer needs to be used for drying. At present, the drying tower is the most widely used for drying grain. When the drying tower is dried, an auger hoist needs to be used to transport the grain to the top of the tower, and then the grain is dried. During the falling process, the grain is dried by contact with hot air. During the drying process, the contact time between the grain and the hot air is short, so it is necessary to repeat the drying several times to reach the storage standar...

Problems solved by technology

[0003] Before storing grain, it is necessary to use a dryer to dry it. At present, the most widely used drying grain is the drying tower. When drying the drying tower, it is necessary to use an auger hoist to transport the grain to the top of the tower, and then the grain During the falling process, the grain is dried by contacting with the hot air. During the drying process, the grain is in contact with the hot air for a short time, so it needs to be dried several times to meet the storage standard. The efficiency is low without drying, and Raising grain multiple times will increase the rate of grain breakage, which is not conducive to grain storage
