According to patent application publication number CN114543493A, a multi-mode integrated hot air drying equipment for granular solid materials relates to a drying device for granular traditional Chinese medicine and solid agricultural products, specifically a multi-mode integrated hot air drying equipment for granular solid materials. This equipment includes, from top to bottom, a preheating and tempering chamber, a drying chamber, a unloading chamber, and an unloading device, as well as an airflow adjustment device installed on the side of the drying chamber, on the same side as the air vent in the corner box inside the drying chamber. However, in the prior art, after the granules are dried, they need to fall into the unloading box. During the discharge process, the unloading box and the opening / closing bottom plate impact and squeeze the granules, easily leading to breakage and damage, thus affecting the quality and economic value of the raw materials. Therefore, improvements to the existing technology are needed. Utility Model Content

[0017] Please see Figure 1-3 The upper end of the unloading box 2 is equipped with a drying mechanism 3, and the upper end of the drying mechanism 3 is equipped with a tempering mechanism 4. The drying mechanism 3 can dry the particles. The outer side of the unloading box 2 is welded with a connecting flange 5, which is connected to the frame 1 by bolts. The connecting flange 5 can support the unloading box 2. The lower end of the full diversion plate 6 has two longitudinal brushes 8, which are symmetrically distributed at the lower end of the full diversion plate 6. The longitudinal brushes 8 are in contact with the transverse brushes 9, and the transverse brushes 9 can seal the side of the unloading box 2.

[0018] Please see Figure 1-3The opening and closing base plate 12 slides in contact with the transverse brush 9, and the longitudinal brush 8 slides in contact with the opening and closing base plate 12. The longitudinal brush 8 can clean the opening and closing base plate 12. A motor 13 is fixedly installed on the outside of the unloading box 2.
