Sealing device is a measure of poultry manure dryer equipment quality is an important indicator of good sealing performance can adapt to the cylinder shape error and axial reciprocating movement during operation, so that equipment wear and tear light to extend the machine's use of time. Therefore, only by selecting the appropriate seal structure to ensure the quality of grain dryer.

 　　

Poultry manure dryer uses different sealing structure although the purpose of the same, but the effect is very different. Seal is to allow air flow through the channel to produce fluid resistance to reduce the amount of air leakage. It is not affected by the movement of the cylinder taking into account the manufacturing errors of the cylinder and the seal itself, the gap between the stiffness and the labyrinthine adjacent to the axis of the cylinder should not be too small.
