Tower-type corn dryer and drying method thereof

Abstract

The invention relates to the technical field of corn processing and provides a tower-type corn dryer. The tower-type corn dryer comprises a vertical-type tower body which is sequentially provided with a feeding port, a drying tower main body, a cooling tower main body and a discharging port from top to bottom. The drying tower main body comprises a plurality of sequentially-connected drying units, and each drying unit comprises a drying tower section and a corn transferring tower section located below the drying tower section. The cooling tower main body comprises a plurality of cooling tower sections of the same structure with the drying tower sections. Each drying tower section comprises an air feeding chamber located in the center, material chambers located in the two sides of the air feeding chamber and waste gas settling chambers located in the outer sides of the material chambers. The material chambers are internally provided with angular box air feeding layers and angular box air discharging layers, and the material chambers in the corn transferring tower sections are internally provided with corn transferring pipelines. According to the tower-type corn dryer, through multiple times of the drying and tempering processes, drying and dewatering are even, the crushing rate is low, and therefore the tower-type corn dryer can be widely applied to the field of corn drying.

Description

technical field [0001] The invention relates to the technical field of corn processing, in particular to a tower-type corn dryer and a drying method thereof. Background technique [0002] With the continuous advancement of agricultural mechanization, the planting and harvesting process of corn is constantly developing towards modern mechanization. In many areas of our country, the harvest season of corn is mostly the rainy season. The traditional way of drying corn will be subject to the weather. Therefore, using Drying corn with a corn dryer can effectively avoid these problems and save drying costs. Relevant data show that: a labor force needs a salary of 35 yuan for drying 400kg of corn in the sun, and 32 yuan for mechanically drying 400kg of corn, which is 3 yuan lower than that. Moreover, mechanically dried corn has better quality and better taste than artificially dried corn. After the corn is dried in a low-temperature cycle, the quality can be improved by one level...

Problems solved by technology

On the one hand, the dryers in the prior art are mainly concentrated on crops such as rice and wheat. On the other hand, due to the excessive drying and high temperature, the phenomenon of grain bursting and cracking is easy to occur, and the drying process is greatly reduced. The quality of corn, in addition, the exhaust gas produced during the drying process of corn contains a lot of dust, which will cause environmental pollution if it is directly discharged into the air
