Grain dryer operation is simple and reliable, but in the actual production also has certain operational requirements, due to the operator of the production process, the lack of mastery of operating methods often appear drying quality does not meet the standard, the following for everyone a brief introduction to the improper operation of grain drying machine caused by the quality of non-compliance:

1.In order to limit the flow rate of the material to the dryer outlet, we only limit the speed of the cylinder to a very low level, so that the number of materials in the cylinder is also greatly reduced. As a result, the number of dynamic contacts with material and hot air is greatly reduced.

2.The required drying material in the biomass dryer cylinder will not be reciprocating. So the material inside the cylinder will soon be hot air pumped away, the storage of material in the cylinder is too low, resulting in material and hot air dynamic and static contact area reduced.

3. Grain dryer only co-current drying, and the drying process of saturated water vapor can not be discharged in time, so water vapor in the drum running distance is too long, resulting in moisture was dry material reabsorption.
