Straw dryer is mainly rely on the heat transfer of the drying medium and water evaporation to achieve drying, the faster the speed of the two processes, the greater the drying speed. So what are the factors that influence the drying speed of the straw dryer?
The greater the contact surface between the drying medium and the straw material, the higher the drying speed. Therefore, when the solid straw material is broken during drying, the surface area can be increased to speed up the drying speed, or the straw material can be dried in a suspended state. In the rotary drum straw drying machine, adding a lifting plate or a grid plate can increase the drying medium. The contact area with the material, increase the drying speed, and shorten the drying time.
