Easy to Use
Highly Versatile
Energy-Efficient and Low-Consumption
The VPD-type rake dryer is primarily used for drying granular, powdered, slurry, or paste-like materials in the chemical, pharmaceutical, and food industries; it is an indispensable and ideal piece of equipment, particularly for drying heat-sensitive and oxidation-prone materials.
The paddle-type vacuum dryer uses heat transfer via a heat-transfer medium for heating and relies on a high-vacuum environment to remove water vapor and solvents. It is suitable for materials that are not heat-resistant, prone to oxidation, prone to dusting, or require solvent recovery.
The material is fed in from the top via a vacuum system, and paddle agitation continuously renews the heat transfer surface. The material is dehydrated through indirect heating using steam, hot water, or hot oil; the high vacuum creates a pressure differential that accelerates water evaporation, resulting in high drying efficiency.
The collector is available in both bag filter and sintered mesh configurations. It features a reverse-blow function to prevent material waste and supports online cleaning and filter cartridge removal without the need to disconnect the vacuum lines.
This equipment is suitable for process operations in sealed, controlled environments, such as in the pharmaceutical and chemical industries, as well as for additives and extracts that are unstable when exposed to air or high temperatures. It is particularly well-suited for powdered materials, granular mixtures, and viscous fluids that require high levels of hygiene.

The gearbox is mounted at the rear and features a partition, making it suitable for cleanrooms. The motor and gearbox are equipped with stainless steel guards, and the base is weighted for stability, eliminating the need for additional mounting. The power is transmitted through the gearbox to drive the impeller and the cylinder at a constant speed.
The dryer consists of an outer casing, an insulation layer, and an inner chamber. The space between the outer casing and the insulation layer is filled with aluminosilicate boards to provide thermal insulation; hot water or heat transfer oil is circulated between the insulation layer and the inner chamber to provide heating; the polished stainless steel inner chamber facilitates cleaning while enhancing heat transfer and increasing the drying speed.
Customizable design, equipped with a bellows protection device, offering excellent sealing performance and simple, efficient operation.
