Description

Technical field:

[0001] The invention relates to the technical field of drying equipment, in particular to a hot air circulation dryer. Background technique:

[0002] The dryer is mainly used in the granulation of pharmaceutical, food, pesticide, chemical fertilizer and other industries and the drying of powdery or granular wet materials. During the drying process of the dryer in the prior art, the material is heated unevenly, which is specifically manifested in that the material near the heating device is heated at a higher temperature, while the material far away from the heating device is heated at a lower temperature. The difference in temperature It is not conducive to the drying of materials and affects the drying effect of materials. In addition, the material of the existing dryer enters from the feed port and is dried once and then discharged directly from the discharge port. The drying is not complete, and the heating energy of the dried material cannot be recycled...
