Durable & Corrosion-Resistant Stainless Steel Drying Solution Our SZG Series Rotary Cone Vacuum Dryer is engineered with a high-grade stainless steel inner shell, ensuring maximum resistance against corrosion and contamination. Designed for the most demanding industrial environments, this machine provides a safe and efficient way to dry strongly irritating, toxic, or easily oxidized materials while strictly adhering to GMP requirements.
Key Technical Advantages:
Corrosion-Resistant Design: The inner shell and heating jacket are built to withstand corrosive chemical powders and fibrous materials, ensuring a long service life and easy cleaning.
Leak-Proof Vacuum Integrity: Utilizing reliable mechanical seals and rotary joints based on American technology, the system maintains a stable vacuum environment (up to -0.15 MPa design pressure) to prevent any leakage of hazardous vapors.
Material Integrity: The slow, 360-degree rotation ensures uniform mixing and drying without destroying the crystallization of delicate materials.
Stable Mechanical Structure: The belt-chain dual-elastic connection maintains perfect concentricity of the shafts, reducing mechanical wear and ensuring smooth, vibration-free operation.
Versatile Heating Options: Seamlessly switch between hot water, low-pressure steam, or thermal oil to meet your specific temperature requirements (20°C to 160°C).
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.
