A kind of interlayer swirling corn drying device

Abstract

The invention relates to an interlayer rotational flow corn drying device, and belongs to the technical field of agricultural product processing. According to the interlayer rotational flow corn drying device, corns on rotatable fixation clamps are dried from all angles by spiral hot air and annular hot air in a drying chamber jointly; while rotating, the rotatable fixation clamps further drives corn cobs to perform circular motion to further improves the uniformity of heating of the corns, and the duration of stay of the spiral hot air in the drying chamber is longer than the time of verticalventilation, so the corn cobs are heated more fully; and waste heat after drying is discharged from a corn transmission channel under the action of a negative pressure fan to separately enter a charging hole and a drying discharge hole, the corn cobs entering from the charging hole are preheated, and the dried corns discharged from the drying discharge hole are subjected to tempering simultaneously. The waste heat is fully utilized, energy sources are saved, the hot air in an interlayer can further play the role of an insulation layer, heat loss in the drying chamber is avoided, and broad application prospects are achieved.

Description

technical field [0001] The invention relates to an interlayer swirling corn drying device, which belongs to the technical field of agricultural product processing. Background technique [0002] The dryer is a device that uses machinery to reduce the moisture content of corn kernels to the range of safe packaging and safe storage, so as to maintain the vitality and vigor of the seeds. It is of great significance to ensure the high yield and harvest of corn and to speed up the circulation of corn. [0003] At present, common corn drying equipment is divided into: 1) Cross-flow grain drying technology, this technology is to make the wet grain flow down from the roof of the warehouse to the drying section by gravity, the hot air passes through the heating section and passes through the valley layer horizontally, and the cold air passes through the cooling section across the valley. 2) Downstream grain drying technology, this technology keeps the hot air and the grain flowing i...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: most of the common drying equipments at present have uneven heating of corn, slow evaporation of water, insufficient utilization of drying waste heat, waste of energy, and no corn preheating program, so when the corn encounters high temperature instantly The defect of waist bursting phenomenon will occur, and a kind of interlayer swirl corn drying device is provided
