The Double Cone Rotary Vacuum Dryer operates by circulating a heating medium (such as hot water, low-pressure steam, or thermal oil) through a sealed jacket, transferring heat to the material inside. Under vacuum conditions, the vapor pressure decreases, causing moisture (or solvent) on the material's surface to evaporate and be efficiently removed by a vacuum pump for recovery.

The paddle dryer is a low-speed agitated drying system equipped with rotating paddles inside the chamber. The wet material is continuously mixed by the paddles, ensuring full contact with the hot air (or thermal medium) and heated surfaces for efficient drying. It typically features a horizontal design with dual or quad shafts.
Paddle dryers are categorized into two types of Convection (Hot Air) and Conduction (Indirect Heating).

The PLG Continuous disc dryer is a highly efficient conduction-type continuous drying equipment. Its unique structure and working principle ensure high thermal efficiency, low energy consumption, compact footprint, simple configuration, easy operation control, and a clean working environment. It is widely used in chemical, pharmaceutical, pesticide, food, feed industries and waste treatment for drying powders, pastes, granules, and heat-sensitive materials.

The ZPG Vacuum Harrow Dryer is an innovative horizontal batch-type vacuum drying system. It operates through conductive evaporation, where a scraper agitator continuously removes material from heated surfaces and promotes cyclic flow within the vessel. Evaporated moisture is extracted by a vacuum pump.

Vacuum drying involves drying materials under vacuum conditions with applied heat. By using a vacuum pump to extract air and moisture, the working chamber is maintained in a vacuum state, significantly accelerating the drying rate of materials while also saving energy. Vacuum drying equipment can be categorized into static dryers and dynamic dryers.

The HZG rotary drum dryer features a slightly inclined cylindrical main body with adjustable rotation speed within a certain range. Wet material is fed into one end of the dryer, where uniformly distributed lifting flights inside the cylinder continuously lift and disperse the material. This ensures even distribution and full contact with co-current (or counter-current) hot air, significantly enhancing heat transfer efficiency and drying dynamics. During the process, the combined action of the inclined lifting flights and hot air flow enables controlled material movement toward the discharge end, where the dried product is discharged through a star valve.

The rotary drum dryer is an internally heated, conduction-type continuous drying equipment. The rotating drum picks up a thin film of material from the bottom feed trough. Heat is transferred through internal pipes to the drum's inner wall, then conducted to the outer wall, and finally to the material film. This process evaporates moisture from the material film, effectively drying the wet product. The dried material is scraped off the drum surface by a blade and collected by a screw conveyor positioned beneath it for packaging.
