A hollow paddle dryer is a low-speed agitated dryer that incorporates a mixing paddle inside the equipment. It allows wet material to be in contact with a heat carrier and a heated surface through the stirring action of the paddles, achieving the drying purpose. The structural form is generally horizontal, with either a two-axis or four-axis design. Paddle dryers are categorized into hot air and conduction types. Hot air drying involves the direct contact between the heat carrier (such as hot air) and the material being dried, while in conduction drying, the heat carrier does not come into direct contact with the material; instead, the heated surface comes into contact with the material.
Hollow Propeller Drying Machine Product Introduction:
This product can indirectly heat or cool pasty, granular, powdered, and slurry materials, enabling unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature combustion. The special wedge-shaped impeller in the equipment offers high heat transfer efficiency and self-cleaning surface area for heat transfer.
