Corn ear fast air drying machine and method

Abstract

The invention relates to a corn ear fast air drying machine and method. The air drying machine comprises a drum body; end covers are arranged at the top and bottom of the drum body; a heating bin, a wind homogenizing bin, an air drying bin and an exhaust channel are sequentially arranged in the cavity in the drum from bottom to top; electric heating pipes are arranged at the bottom of the heating bin; a blast hole is formed in the drum body; a wind homogenizing plate is arranged between the heating bin and the wind homogenizing bin; a temperature sensor is arranged in the wind homogenizing bin; a turntable is placed at the inner wall of the air drying bin and is provided with through holes; the drum body is provided with a loading side door convenient to open; a flexible clamping plate is arranged at the inner wall of an air duct cylinder; a temperature sensor and a humidity sensor are arranged in the exhaust channel; a liquid crystal display panel is arranged at the outer part of the drum body. The invention also discloses an air drying method, air outlets for entering the air drying bin are arrayed in sequence, large-flow air flows are formed, the air flows can be used for air drying at inner and outer sides of corn ears, air drying can be fast formed and the air drying speed is improved by more than four times compared with the natural air drying speed.

Description

technical field [0001] The scheme relates to a small-batch corn ear rapid air-drying equipment and method suitable for laboratory use for the selection and breeding of new corn varieties, and is mainly aimed at the breeding process. Background technique [0002] At present, the corn dryers sold on the market are mainly used for drying commercial grains, and there is no corn ear dryer dedicated to breeding. And the commercially available dryers mainly have the following characteristics: first, it is used to dry corn kernels; second, it is large in size and has a large drying capacity, and cannot be used for drying a small number of experimental seeds; third, it has high temperature and high dehydration speed. Fast, the drying of corn seeds will affect the activity of corn seeds; Fourth, the heat source used is mainly coal, fuel oil or other biomass fuels. [0003] The process of corn breeding has special characteristics: first, the amount is small, and it is urgent to develo...

AI Technical Summary

Problems solved by technology

Based on the above characteristics, the existing corn dryer has the following characteristics that are not suitable for drying seeds for breeding: First, corn seeds are harvested as ears, and the water content is too high (about 35%) to be threshed, and the threshing damage is serious , so the machinery used for grain drying is not suitable for drying corn ears; second, the amount of seeds in the breeding process is small, and different seeds cannot be mixed. The existing rotating and stirring dryers are not suitable for testing seed drying. Third, the goal pursued by the existing drying equipment is dehydration efficiency without maintaining seed activity, so high-efficiency dehydration will easily lead to seed inactivation, making breeding scientific research work unsustainable; fourth, the experimental seed treatment site is a laboratory rather than a large-scale Factory buildings, not suitable for using coal, gas, oil or other biofuels as heat source raw materials
