CE 360° Rotation Vacuum Drying Machine For Uniform Batch Drying

Advanced 360° Rotating Vacuum Technology for Uniform Batch Quality

The SZG Series Vacuum Drying Machine is designed to provide unparalleled consistency for industrial batch processing. By utilizing a 360-degree rotating double cone tank, the material is continuously and gently mixed, ensuring every particle comes into contact with the heated inner shell. This eliminates "cold spots" and achieves 100% uniform drying results in a significantly shorter time.

• Uniform Mixing & Drying: Driven by a steady power source, the slow rotation continuously permeates moisture from the material's core to its surface, where it evaporates instantly under vacuum.

• CE Standard Reliability: Built to international quality standards, our machines feature a belt-chain dual-elastic connection that ensures perfect shaft concentricity and vibration-free operation during the entire rotation cycle.

• High-Efficiency Heat Transfer: The jacketed design supports hot water, steam, or thermal oil, delivering more than twice the thermal efficiency of traditional static drying ovens.

• Advanced Sealing System: Equipped with American-technology mechanical seals, the machine maintains a high vacuum integrity (-0.15 MPa), making it perfect for solvent recovery and drying easily oxidized materials.

• GMP Compliant & Easy to Clean: The mirror-polished interior and indirect heating system prevent contamination, making it ideal for the most sensitive pharmaceutical and food-grade batches.

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.
