PLG-2500×16 Disc Dryer for Herbal Residue

The disc continuous dryer is a vertical drying device featuring multiple fixed discs and rotating rakes for stirring. Its structure consists of metal discs of varying sizes arranged alternately from top to bottom, each disc being composed of two metal plates forming a hollow disc. The heating medium includes steam, thermal oil, and hot water. Steam, thermal oil, and hot water are introduced into the discs, transferring heat to the material on the discs through the metal walls via conduction. The material to be dried enters the dryer from the upper feed inlet and lands on the first layer of small heating discs. Under the action of the rake blades, the material moves from the inside of the small disc outward and is then transferred from the outer periphery to the next layer of large discs. Due to the inward angle of the rake teeth on the large discs, the material is pushed toward the interior of the disc as the rake teeth rotate. The material repeatedly moves downward in this manner while being dried. The evaporated moisture is discharged by a fan (and can be recovered via a condenser). The heat transfer area of the dryer can be ensured by adjusting the number of discs, while the required residence time of the material in the dryer can be controlled by adjusting the rotation speed of the main shaft, i.e., by using the rake teeth to regulate the material's movement speed. This results in a qualified dried product at the bottom.
