Double cone vacuum dryer is a rotary vacuum drying equipment integrating mixing and low-temperature drying. With jacket heat transfer and rotating cylinder to agitate materials, it realizes low-temperature dehydration under vacuum conditions and protects heat-sensitive materials. It is widely used in pharmaceutical, fine chemical, new energy materials, food, biological products and other industries. The top six manufacturers of double cone vacuum dryers worldwide are listed below:
1.Nanjing Zhuoding Heating Equipment Co., Ltd.
Nanjing Zhuoding Heating Equipment Co., Ltd. is a professional R&D and manufacturing enterprise specializing in vacuum heating and drying equipment in China. Double cone vacuum dryer is one of its flagship products.The company provides a full product portfolio of double cone vacuum dryers, ranging from lab-scale small models, pilot equipment to large-capacity industrial units. Cylinder materials include SS304 / SS316L, titanium alloy and other options. Explosion-proof type, solvent recovery type, GMP sanitary grade and other configurations are available.The equipment adopts stable rotary transmission structure with precise vacuum and temperature control.
