1、 Working principle and characteristics of disc continuous dryer:

Disc continuous dryer is a new type of conductive drying equipment, which has the advantages of continuous operation, closed operation, high evaporation intensity, reasonable humidity gradient distribution, low power consumption, and small footprint. At the same time, its configuration is simple and does not require dust post-treatment equipment such as cyclone dust collectors and bag filters that must be equipped with airflow dryers. It does not use hot air as a heating medium, so there will be no product loss caused by poor separation of hot air and dust carried by exhaust gas.

The disc continuous dryer consists of a drying disc, a rake arm, several rake blades mounted on the rake arm, a main shaft, a rotating device, a housing, etc. One end of the hollow drying disc is filled with hot water, and the other end is discharged for cyclic use. Drying discs are divided into two types: large and small discs. They are arranged horizontally in layers inside the dryer. The drying disc is stationary, and the material moves from the outside to the inside on the large disc under the action of the rake blades, falling from the inner edge of the large disc into the inner edge of the small disc. The material moves from the inside to the outside on the small disc, falling from the outer edge of the small disc into the large disc. The material is transported, flipped, and moves in an Archimedean spiral trajectory on the drying disc by the rake blades. During the movement, it is heated by the drying disc and undergoes heat and mass transfer to complete the drying operation. Based on the yield, properties, initial and final moisture content of the dried material, the number of layers (drying area) of the drying disc is determined. The disc dryer operates vertically, with wet materials added through the top feeding port and discharged from the bottom of the dryer after passing through each layer of drying discs. The entire drying process is sealed, and the moisture released from the materials is directly discharged into the atmosphere through the exhaust pipe at the top of the dryer. The main component of the exhaust gas is water vapor, which is not carried by the dried products and does not cause environmental pollution.
