Rotary vacuum drying machine
Model：SZG Series Double Cone Rotary Vacuum Drier
The Double Cone Rotary Vacuum Drying Machine, also known as Double Cone Rotary Vacuum Dryer, Double Cone Vacuum Dryer, Rotary Double Cone Vacuum Dryer and Conical Rotary Vacuum Dryer, is a multifunctional low-temperature vacuum drying and mixing integration equipment. It also covers alternative names including Double Cone Rotary Vacuum Drier, Rotary Vacuum Drier, Rotary Vacuum Dryer and Rotating Vacuum Drying Machine. Widely applied in pharmaceutical, chemical, food, metallurgy, building materials and other industrial fields, this machine is specially designed for drying and mixing powder, crystalline and granular materials. It also supports solution concentration, material disinfection and sterilization, serving as an all-in-one industrial processing device.
Featuring excellent drying performance, the equipment can dry materials with various initial moisture contents down to a final moisture content below 0.5%. It is energy-saving and labor-saving with high working efficiency. For materials with initial moisture content less than 40%, the standard drying cycle only takes 2 to 4 hours. With low labor intensity and stable batch production capacity, it is an ideal drying solution for standardized industrial production.

Working Principle
This rotary vacuum dryer adopts advanced vacuum low-temperature indirect heating drying technology. During operation, materials are placed in a fully sealed double-cone vessel under continuous vacuum condition. Heat medium circulates inside the equipment jacket to achieve indirect uniform heating of materials, avoiding direct contact heating and protecting material properties.The double cone vessel rotates slowly and continuously in forward and reverse directions with automatic timing reversing function. The constant tumbling and flipping motion fully stirs materials, continuously renews the material surface, and greatly accelerates the evaporation of internal moisture and solvent. All evaporated gas and vapor is quickly extracted and discharged by the vacuum pump. A matched solvent recovery device can be equipped on demand to realize recycling of evaporated liquid and reduce production waste.
The bidirectional timing rotation makes full use of the entire heat transfer area inside the vessel, ensuring uniform heating of all materials and significantly improving drying efficiency. The vacuum low-temperature drying principle effectively reduces the boiling point of moisture and solvent, realizing efficient drying at low temperature without damaging material structure and activity.
Core Advantages & Application Characteristics
1. Special Material Adaptability: Perfectly suitable for heat-sensitive materials, easily oxidizable materials, non-damageable crystalline materials, recyclable solvent materials, as well as highly irritating and toxic materials, solving the drying difficulties that ordinary dryers cannot handle.2. Uniform Drying & Stable Quality: Integrating mixing and drying functions, the continuous rotary flipping ensures uniform heating and drying of each batch of materials with consistent finished product quality.
3. Pollution-Free & Sanitary Design: Fully sealed vacuum drying structure with no dead corners inside the vessel effectively avoids external pollution and material cross-contamination, meeting high-standard production requirements for pharmaceutical and food industries.
4. Easy Operation & Low Maintenance: Optimized sealing structure delivers excellent sealing performance and stable vacuum degree. The equipment features simple operation, convenient disassembly, easy cleaning and low daily maintenance cost.
5. High Efficiency & Energy Saving: Low-temperature vacuum drying reduces energy consumption, and the full utilization of heat transfer area shortens the drying cycle, realizing high-efficiency and energy-saving batch production.
