Large Capacity Vacuum Drying Machine For Heat Sensitive Materials

High-Volume Vacuum Drying Solution for Sensitive Materials The SZG Series Large Capacity Vacuum Drying Machine is the ideal solution for industrial-scale drying of heat-sensitive, volatile, and easily oxidized materials. With a maximum tank capacity of 5000L, this equipment allows for mass production while maintaining the delicate molecular and crystalline structure of your products through low-temperature vacuum evaporation.

Why Choose Our Large-Capacity SZG Dryer?

• Mass Production Ready: Our range covers loading volumes from 50L up to 2500L (5000L total capacity), ensuring we can meet the demands of large-scale chemical and pharmaceutical facilities.

  
  

• Gentle Drying Process: By operating under a vacuum (design pressure -0.15 MPa), the boiling point of moisture is significantly lowered, allowing for rapid drying at temperatures as low as 20°C to 85°C inside the can.

• Superior Thermal Efficiency: Our jacketed design achieves more than twice the thermal efficiency of ordinary drying ovens, drastically reducing energy costs for large batch cycles.

• Mechanical Reliability: For large-scale rotation, our belt-chain dual-elastic connection and American-technology mechanical seals ensure the machine runs stably with perfect concentricity, even at full load.

• Versatile Application: Effectively handles powdered, granular, and fibrous materials in the chemical, pharmaceutical, and food industries, especially those requiring solvent recovery.

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.
