Double Cone Rotary Vacuum Drying Machine For Pharmaceutical Chemical Powders

Double Cone Rotary Vacuum Drying Machine For Pharmaceutical Chemical Powders

Advanced SZG Series Vacuum Drying Solution for Sensitive Powders Our Double Cone Rotary Vacuum Drying Machine is specifically engineered for the pharmaceutical and chemical industries. By lowering vapor pressure under vacuum, it ensures rapid evaporation and solvent recovery at low temperatures, preserving the integrity of heat-sensitive, easily oxidized, and crystalline materials.

• Industry Compliance: Fully meets GMP standards with an easy-to-clean, mirror-polished inner shell.

• Operating Stability: Utilizes a unique belt-chain dual-elastic connection and American-technology mechanical seals for leak-proof, steady rotation.

• Thermal Efficiency: Offers 2x the efficiency of traditional drying ovens, with automatic temperature control ranging from 20°C to 160°C.

• Material Versatility: Ideal for drying, mixing, and concentrating powdered, granular, and fibrous materials including biochemical products and mineral raw materials.

Working Principle

◎ Heat energy (such as hot water, low-pressure steam, or heat transfer oil) is introduced into the sealed jacket, and the heat is transferred to the material being dried through the inner shell.

◎ Driven by a power source, the tank rotates slowly, continuously mixing the material inside, thereby enhancing the drying process.

◎ The material is under vacuum, and the decrease in vapor pressure causes the moisture (solvent) on the material surface to reach saturation and evaporate, which is then promptly discharged and recovered by the vacuum pump. The process of moisture (solvent) inside the material continuously permeating to the surface, evaporating, and being discharged continues, allowing the material to achieve its drying purpose in a very short time.

Performance Characteristics

◎ When heated by oil, automatic temperature control is used, suitable for drying biochemical products and mineral raw materials.

◎ Temperatures can range from 20 to 160°C.

◎ High thermal efficiency, more than twice that of ordinary ovens.

◎ Indirect heating prevents material contamination, meeting GMP requirements. The equipment is easy to maintain, operate, and clean.

◎ Recommended process setup demonstration: solvent recovery process setup.

Suitable Materials

Suitable for the concentration, mixing, drying of powdered, granular, and fibrous materials in the chemical, pharmaceutical, and food industries, as well as materials requiring low-temperature drying (such as biochemical products). Especially suitable for drying easily oxidized, volatile, heat-sensitive, strongly irritating, toxic materials, and materials for which crystallization cannot be destroyed.

Technical Specifications

Note: For materials whose volume changes significantly before and after drying, the loading coefficient can be appropriately increased or decreased.
