Corn dryer is a piece of equipment specially used to dry corn kernels. During the drying process, corn kernels are dried by hot air to reduce moisture content, improve quality and preserve time. So, what is the working temperature of the corn dryer?

The working temperature of the corn dryer will vary at different working stages, and is mainly determined by the following factors: hot air temperature, hot air speed, corn kernel thickness, corn kernel moisture content, etc.

First of all, the hot air temperature is one of the important factors affecting the working temperature of the corn dryer. The higher the hot air temperature, the higher the temperature of the corn kernels will be during the drying process. Normally, the hot air temperature is between 60°C and 85°C. This temperature range is considered to be a more suitable range for corn drying. Too low a temperature may lead to poor drying effect, and too high a temperature may cause problems such as burning of corn kernels.

Secondly, the hot air speed will also affect the working temperature of the corn dryer. The faster the hot air speed, the larger the contact area between the corn particles and the hot air, and the faster the drying speed. The hot air speed is generally between 1~3m/s and will be adjusted according to the design of the dryer and the characteristics of the corn particles. During the drying process, the rapid hot air can quickly take away the moisture on the surface of the corn kernels, thus increasing the temperature of the corn kernels.

In addition, the thickness and moisture content of corn kernels will also affect the operating temperature of the dryer. Normally, the thicker the corn kernels are, the longer the drying time will be, and the hot air temperature needs to be increased accordingly. The moisture content will also affect the drying time and temperature of corn kernels. The higher the moisture content, the higher the temperature required for drying to achieve the purpose of reducing the moisture content.

To sum up, the working temperature of the corn dryer is between 60°C and 85°C. The specific temperature will be adjusted according to factors such as hot air temperature, hot air speed, corn particle thickness and moisture content. In actual use, debugging and operation need to be carried out according to specific conditions to ensure that the corn kernels can be properly dried, thereby improving quality and storage time.
