[0002] Hot air dryer is a device that uses hot air to dry materials. The air is heated by a heating device (such as electric heating, gas heating, etc.), and then the hot air is blown into the drying chamber by a fan, where it fully contacts the materials and takes away the moisture in the materials, thereby achieving the purpose of drying. With the help of an air knife, the materials can be dried in a shorter time. It can be used to dry many different types of materials, such as wood, textiles, etc. Compared with some other drying technologies, the equipment and operating costs are relatively economical.
