Drying machine for grain production

Abstract

The invention discloses a drying machine for grain production. The drying machine comprises a feeding chamber, a spiral feeding rod, a feeding port, a driving device, an air outlet, a humidity detecting device, a motor, a steam boiler, an air blower, a temperature regulating device, a mixing shaft, mixing blades and a conveying device, wherein the spiral feeding rod is fixed to the inner side of the feeding chamber, and the right end of the spiral feeding rod is connected with the driving device; a drying chamber is fixed to the bottom side of a rust removing pipe; the steam boiler which is connected with the air blower is positioned at the upper right of the drying chamber; a motor is mounted at the left side of the steam boiler, and the bottom end of the motor is connected with the mixing shaft; the temperature regulating device is embedded into the outer wall of the mixing shaft; the mixing blades are arranged at two sides of the mixing shaft. The drying machine for the grain production is simple and novel in structure; the feeding speed can be freely controlled through the spiral feeding rod; the humidity of the discharged air can be detected through the humidity detecting device; the materials can be fed after the humidity meets the requirement, so that the drying efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of grain drying devices, in particular to a grain drying machine. Background technique [0002] China is the largest grain producer and consumer country in the world. According to statistics, every year due to climate reasons, the grain is too late to dry or does not meet the safe water storage standards, resulting in moldy and germinated grains as high as 5%. 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, the equipment consumes high energ...
