Autumn is the harvest season. In the north, most are corn. So after harvesting the corn ears, what to do with the straw? In the past, we relied on God for food. When the weather was fine, everyone would spread out corn stalks to dry in the sun. However, this was not only time-consuming and labor-intensive but also ineffective. Nowadays, with the development of mechanization, people generally use dryers for operation, which saves time and effort, and the efficiency has also been improved.

Working principle of straw dryer;

1. Straw dryers generally adopt a drum-type structure. By controlling the heating device, the temperature of the hot air is suitable and maintained within a suitable temperature range. The high-temperature quick-drying process or low-temperature steam drying process is used to quickly evaporate and gasify the moisture in the corn stalks. The dried corn stalks have low water content and low nutrient loss, and can be used for feed or fuel production to realize straw resource utilization and high-value reuse. .

2. In the drying chamber, the hot air comes into contact with the corn stalks with high humidity, thereby heating and evaporating the moisture in the corn stalks and taking away the moisture. At the same time, the hot air also becomes humid as the water evaporates. Next, the humid hot air is cooled through the heat exchange device to condense the moisture, and then the cooled hot air is heated again and recycled.

3. The corn straw dryer can dry quickly with high-temperature hot air and has a large processing capacity. It can dry more than ten tons, dozens of tons or even hundreds of tons a day, and the working time is not limited. You can work for as many hours as you want. Either way. This equipment can produce continuously, has high flexibility, stable equipment operation, and high drying efficiency. It can reduce the moisture in corn stalks to about 12%-15%.
