Corn ear and kernel linkage drying production line

Abstract

The invention discloses a corn ear and kernel linkage drying production line. The production line comprises a ear drying machine, a corn thresher, a grain cleaning and separating machine, a kernel drying machine and a finished product warehouse, wherein the ear drying machine is used for drying corn ears; the corn thresher is used for threshing dried corn ears; the grain cleaning and separating machine is used for cleaning and separating the threshed corn kernels; the kernel drying machine is used for drying the cleaned and separated corn kernels; the finished product warehouse is used for storing the dried corn kernels; an exhaust air outlet of the kernel drying machine is connected to an air inlet of the ear drying machine through a pipeline, the corn ears are dried by utilizing waste heat of the kernel drying machine, a fan is arranged at the air inlet of the ear drying machine, and the fan is connected with a controller. According to the corn ear and kernel linkage drying production line, the whole process flow of "ear drying, kernel threshing, cleaning and separating, kernel drying and warehousing" is realized with leaving no step, and great significance is brought to the cornhigh-quality rapid warehousing.

Description

technical field [0001] The disclosure belongs to the technical field of corn cob drying, and in particular relates to a corn cob drying production line. Background technique [0002] With the development of corn harvesting mechanization technology, there are two main methods of corn harvesting: segmented harvesting and direct harvesting of grains. In the Huang-Huai-Hai area, due to factors such as the two-crop rotation planting model, the lack of direct-harvesting corn varieties, and backward direct-harvesting equipment, it is difficult to promote direct harvesting of corn kernels, and the corn ear harvesting mode accounts for more than 90%. [0003] At present, the main technical mode adopted is "ear harvesting by machine → yard drying → mechanical threshing → grain drying". However, corn ears are prone to mildew, insect damage, and rodent damage during the drying process in the yard, which seriously affects the quality and use of corn. The thermal efficiency of the existi...

AI Technical Summary

Problems solved by technology

[0003] At present, the main technical mode adopted is "harvesting ears by machine→drying in the yard→mechanical threshing→drying the grains". However, during the drying process in the yard, corn ears are prone to mildew, insect damage, rodent damage, etc., which seriously affect the quality and use of corn.

The thermal efficiency of the existing grain drying equipment is low, only about 55%, and the temperature of the exhaust gas and flue gas is high, which wastes a lot of heat; the corn husks in the exhaust gas are directly discharged, polluting the environment
