Professional Reliable Double Cone Rotary Vacuum Dryer For Mass Production Drying

Professional Reliable Double Cone Rotary Vacuum Dryer For Mass Production Drying

Reliable Industrial Drying Solution for Large-Scale Manufacturing The SZG Series Professional Double Cone Rotary Vacuum Dryer is engineered to meet the rigorous demands of mass production drying. Combining advanced domestic and international technologies, this equipment offers an exceptionally stable and efficient drying process for industries requiring high-volume output without compromising on product quality.

Core Advantages for Mass Production:

• Proven Mechanical Reliability: Unlike traditional dryers, our system uses a belt-chain dual-elastic connection. This ensures the perfect concentricity of the two shafts, allowing the machine to operate stably during 24/7 continuous production cycles.

• Massive Capacity Options: Designed for scale, our series ranges from 100L to 5000L (with loading volumes up to 2500L), making it the go-to choice for large-scale pharmaceutical and chemical processing plants.

   

• Exceptional Energy Efficiency: The jacketed heat transfer design achieves over 200% the thermal efficiency of standard ovens, significantly lowering the operational cost per kilogram of dried material.

   

• Precise Process Control: Features automatic temperature regulation (20°C to 160°C) and optional stepless speed regulation (SZG-A), providing professional-grade precision for complex drying curves.

   

• Robust Sealing Technology: Equipped with American-technology mechanical seals and rotary joints, the system maintains high vacuum integrity (-0.15 MPa), ensuring safe solvent recovery and preventing material contamination.

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.
