Drying device for corn processing

Abstract

The invention discloses a drying device for corn processing. The drying device comprises a drying bin, a feed port, a motor, air outlets, a material outlet, a hot air box, a dust suction pipe, a dust treatment bin, a carrying plate, a hot air pipe, baffles, vent holes, a filter screen, a finished product groove and a residue groove. The drying device has the beneficial effects that the carrying plate is arranged to be of a structure which spirally descends around the hot air pipe so that corn kernels can roll conveniently on the carrying plate, the contact area between the corn kernels and hot air can be increased, and therefore the drying speed of the corn kernels can be increased; the hot air pipe is of an annular structure so that the hot air recycling effect can be achieved just by connecting one end of the hot air pipe with the hot air box, the hot air enters the hot air pipe from the tail part after moving around for a circle, and therefore the energy consumption of the drying device can be greatly reduced; the carrying plate is divided into two layers, the upper layer is composed of the filter screen, and therefore the corn kernels can be separated from residues; and the drying efficiency is high, the energy consumption is low, and the residues can be conveniently separated.

Description

technical field [0001] The invention relates to a drying device, in particular to a drying device for corn processing, which belongs to the application field of agricultural product processing. Background technique [0002] With the improvement of grain varieties and the increase of per unit yield, the yield per mu of corn kernels has gradually increased. The traditional drying method is no longer suitable for a large number of corn kernels. The corn kernel dryer is an ideal equipment for drying grain and oil. [0003] However, the existing drying device still has certain defects in use. Although the existing drying device can dry the corn kernels, it needs to provide a large amount of hot air to dry the corn kernels due to the large amount of corn kernels. , so that the energy consumption and operating cost become very high, and the corn kernels have a small contact surface with the hot air during the drying process, and most of the corn kernels are piled up. The inner corn...

[0003] However, the existing drying device still has certain defects in use. Although the existing drying device can dry the corn kernels, it needs to provide a large amount of hot air to dry the corn kernels due to the large amount of corn kernels. , so that the energy consumption and operating cost become very high, and the corn kernels have a small contact surface with the hot air during the drying process, and most of the corn kernels are piled up. The inner corn kernels cannot touch the hot air, but the temperature of the outer corn kernels is low If it is too high, such unbalanced drying will easily damage the corn kernels, and the residue on the corn kernels cannot be cleaned well, and covering the corn kernels will also affect the drying of the corn kernels
