The first important part of corn dryers is the hot-blast furnace. The following types like the coal-burning furnace, fuel-burning furnace, natural gas burning furnace, and bio-fuel burning furnace will be available for users. The main function of the furnace is to provide a dryer with hot air as the drying medium.
The most important part of the corn dryer is the drying machine. Its internal components are mainly composed of air intakes and angular boxes.
In the whole process, the raw grain will first fill the drying container, then the hot-blast generated by the furnace will go through the air intakes and enter the inside of the machine. Corn flows slowly from top to bottom by gravity. Meanwhile the hot airflow through the corns layer by layer. In this process, heat is transferred from hot air to grain material to raise the grain temperature to make the moisture inside the material evaporate into the air and become exhausted air, then discharged into the air through the angular boxes. if the working temperature inside the dryer exceeds 150 degrees, or the temperature of corn more than 60 degrees, the quality of corn will be greatly affected. Corn dryer of Zhengzhou New Energy Technology Co.,Ltd , select the technology of tempering process, alternating high and low temperature drying multi-level segment, the corn into the cooling section, after cooling, cooling grain to grain storage temperature, then discharged from the grain discharge section greatly to ensure the quality of maize, but also save energy, making breakage rate of corn to 3‰ or less.
Corn dryer makes use of the clean hot air as the heat medium to dry grain. The interior of dryers is composed of angular ventilation boxes, which are arranged in a staggered arrangement. The angular boxes are filled with grains flowing downward. The hot air enters the intake angular box through the grain layer and passes through the grain layer from above to below. The exhaust gas is discharged through the exhaust angular boxes.
