Hot air repeatedly through the material layer and the reverse flow of materials, heat exchange full, high thermal efficiency.
Compact, small footprint.
Materials in the bed residence time can be regulated, convenient operation.
Spiral bed along the bottom-up materials for the circular motion at the same time, also have their own jump, thus increasing the materials and hot air contacts and enhanced the drying effect.
Continuous access to material suitable for the pipeline, and easy to achieve "GMP" standards, instead of the traditional box-type drying.
Materials on the basic shape of the surface and there is no damage, not only guaranteed that the roundness of the pills, but also greatly reduce the fragmentation of the pills.
Wet materials since I entered the feed screw top bed, in the week to the exciting force and the effects of gravity, and materials along the spiral bed for jumping movement from top to bottom, until the bottom of the material at the same time, clean hot air from Spiral bed at the bottom of entry, and distribution of materials in the bed full of heat transfer and mass transfer, I discharged from the top of Baishi. So that drying wet materials to achieve the objective.
