Necessity of secondary air pipe of potato residue dryer

Author: Dingli     Date: 2020-03-12  

  Some dryers use secondary air ducts. The secondary air ducts can quickly increase the temperature inside the drum again to bring the temperature of the inlet to a certain temperature, and quickly and effectively dry materials with excessive moisture to meet the qualified standards. Today, I will show you the secondary air pipe in the potato residue dryer.

  Due to the excessive amount of induced air when the potato dregs dryer is operating or the external temperature is too low in winter, the heat loss is serious or the seal is not tight enough, which causes a large temperature difference between the upper and lower ends of the drum to affect the drying effect, this phenomenon is particularly serious when the diameter of the drum is large. Although these factors can be solved through proper adjustment, the tendency of the intake side of the drum to suck a lot of cool air during work is inevitable. In this case, only the secondary air inlet pipe can be used to adjust and solve.

  In order to improve the drying time of potato dregs in the drum so as to achieve the best drying effect, the secondary air inlet pipe must be considered in all aspects when installing. Generally, the higher the installation, the better it is installed on the drum body. Then the other ducts are arranged in order downward.
