GMP High Efficiency Double Cone Rotary Vacuum Dryer For Industrial Drying
Product Description:
GMP compliant SZG Double Cone Rotary Vacuum Dryer (100L-5000L). High-efficiency drying for heat-sensitive, toxic, and volatile materials at 20-160°C. Features dual-elastic connection and stable vacuum seals for industrial chemical & pharma use. Request a quote!
The SZG Double Cone Rotary Vacuum Dryer is a new generation of high-efficiency drying equipment designed by combining domestic and international technologies. Featuring a belt-chain dual-elastic connection, it ensures exceptionally stable operation and concentricity.
Temperature Range: 20°C to 160°C with automatic control.
Compliance: Fully meets GMP requirements for pharmaceutical and food industries.
Best For: Heat-sensitive, easily oxidized, and toxic materials that require low-temperature drying without destroying crystallization.
Versatility: Compatible with hot water, low-pressure steam, or thermal oil as heating media.
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.
