Low Temperature Customized Double Cone Rotary Vacuum Dryer For Industrial Drying

Low Temperature Customized Double Cone Rotary Vacuum Dryer For Industrial Drying

Precision Low-Temperature Drying for Sensitive Industrial Materials Our Customized Double Cone Rotary Vacuum Dryer is specifically engineered for industrial processes that require strict temperature management. By utilizing a high-vacuum environment, this machine lowers the boiling point of solvents, allowing for rapid evaporation at temperatures as low as 20°C. This ensures that heat-sensitive, volatile, and easily oxidized materials are dried thoroughly without compromising their chemical or crystalline integrity.

Technical Advantages Based on the SZG Series:

• Precise Low-Temperature Control: Features an automatic temperature regulation system compatible with low-temperature hot water or thermal oil, maintaining a stable range from 20°C to 160°C.

• High-Efficiency Vacuum Evaporation: Under vacuum (design pressure up to -0.15 MPa), moisture on the material surface reaches saturation and evaporates quickly, which is then promptly recovered by the vacuum system.

• Stable Mechanical Performance: Our unique belt-chain dual-elastic connection ensures the concentricity of the shafts, providing smooth, vibration-free rotation even during prolonged low-temperature cycles.

• Customized Internal Mechanisms: For viscous or sticky materials, we provide tailored "lifting plate" mechanisms and internal ball bearings to ensure continuous mixing and uniform heat distribution.

• GMP Standard Design: The indirect heating method prevents any contact between the heat medium and the material, ensuring the highest purity levels for pharmaceutical and biochemical products.

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.
