grain dryer

Abstract

The invention discloses a grain dryer, which belongs to the technical field of agricultural food preservation and processing. It mainly includes a drying device; the drying device includes more than one set of drying and slowing devices and a terminal drying cylinder, and the drying and slowing device includes a drying cylinder and a slowing cylinder connected in sequence, and the slowing cylinder and the drying cylinder are connected in sequence. The terminal drying cylinder is connected; the drying cylinder and the terminal drying cylinder are respectively connected to the pipeline; the drying device is connected to the conveying equipment through a cleaning device, and the cleaning device includes a material inlet and an air inlet. A primary deflector is provided, a secondary deflector is provided obliquely below the primary deflector, and a discharge port is provided directly below the primary deflector. The invention has the advantages of simple structure, convenient use, easy repair and maintenance, large drying capacity, good performance of dried grain products, and greatly reduced waist burst rate and broken rate. The invention is mainly used for grain drying.

Description

technical field [0001] The invention belongs to the technical field of agricultural food preservation and processing, and in particular relates to a grain dryer and a drying method. Background technique [0002] China is the world's largest grain producer and consumer. According to statistics, every year due to climate reasons, the grain is too late to dry or does not meet the safe water storage standard, resulting in about 5% of the grain moldy and germinated. According to the National Bureau of Statistics In 2014, the total national grain output was 607.099 million tons, which is equivalent to a loss of more than 30 million tons of grain every year. At present, the method of grain drying generally relies on the heat source to sprinkle the required grain under the action of gravity or machinery, and let the water slowly dissipate under the action of conduction, convection and radiation, so as to achieve the purpose of grain drying; however, The drying method is complicated...

AI Technical Summary

Problems solved by technology

At present, the method of grain drying generally relies on the heat source to sprinkle the required grain under the action of gravity or machinery, and let the water slowly dissipate under the action of conduction, convection and radiation, so as to achieve the purpose of grain drying; however, The drying method is complex, the equipment consumes high energy, the level of automation is low, and the investment is large.

[0003] The existing tumble dryer is mainly composed of a hot air stove, a drying cylinder, a fan, and conveying equipment. It has a simple structure, convenient maintenance, and low cost. The drying effect of the grain is not ideal, and the output is low; at present, there is no efficient, simple, energy-saving and environment-friendly drying machine and drying method suitable for large agricultural machinery households, large grain growers and village groups.
