Advanced Conical Design for Superior Drying Uniformity
The SZG Series Conical Vacuum Drying Machine is engineered for precision and hygiene.By utilizing a slow-rotating double cone structure, the material is continuously mixed in a 360-degree motion, ensuring complete uniform drying and preventing local overheating. This makes it the premier choice for delicate pharmaceutical and food-grade powders.
Why Our Design Stands Out:
Uniform Drying Performance: Driven by a stable power source, the tank's rotation ensures every particle contacts the heated inner shell. This continuous mixing, combined with vacuum moisture removal, achieves the drying purpose in a significantly shorter time.
Easy-to-Clean & Maintenance: Designed strictly to GMP standards, the equipment features a smooth, mirror-polished interior that prevents material buildup. The simplified structure and reliable mechanical seals make it exceptionally easy to sanitize between batches.
Optimized for Viscous Materials: For materials that tend to stick, we offer a "lifting plate" mechanism or internal ball bearings to ensure the material stays in motion, further enhancing drying uniformity.
Precise Temperature & Speed Control: Our SZG-A model offers stepless speed regulation and constant temperature control (20-160°C), allowing you to tailor the rotation to your material’s specific flow characteristics.
Energy-Efficient Operation: The indirect heating jacket system provides more than twice the thermal efficiency of ordinary drying ovens, saving energy while protecting the material from 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.
