The double cone rotary vacuum dryer is suitable for the concentration, mixing and drying of powdery, granular and fibrous materials in the chemical, pharmaceutical, food and other industries, as well as materials that need to be dried at low temperature (such as biochemical products, etc.) Drying of volatilized, heat-sensitive, highly irritating, toxic materials and materials that are not allowed to destroy crystals.
The two-stage elastic connection mode of belt/chain is adopted, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts. Both the heat medium and the vacuum system use reliable mechanical seals or American technology rotary joints. The machine can not only stepless speed regulation, but also constant temperature control. The heat medium is available from high temperature heat transfer oil, medium temperature steam and low temperature hot water. When drying viscous materials, a "copyboard" structure is specially designed for you inside the tank.
Plate vacuum dryer is also called disc vacuum dryer. It is a multi-layer fixed hollow heating disc (also known as a loading tray), a rotating harrow stirring, a vertical continuous Conduction-based drying device.
Low-temperature belt continuous vacuum dryer is a new concept of high-efficiency and energy-saving drying equipment successfully developed after repeated comparison of the advantages and disadvantages of conventional spray drying and freeze drying. It is used in traditional Chinese medicine, western medicine, chemical industry, food, health care. In the drying of products in industries such as powder and other industries, spray drying is beneficial to the cost, but the solubility of the product, the original flavor and the shape of the powder have major defects, and it is powerless for products with slightly higher viscosity and heat sensitivity requirements. Conventional freeze-drying yields excellent product solubility and high quality, but yields are too low and expensive.
The technical indicators of the low-temperature continuous vacuum dryer are just between the above two kinds of equipment. It can make the dried product form a porous and loose shape, retain the original material properties of the product, and have a good appearance. Because it is vacuum low-temperature drying, it can be Meet the processing requirements of most heat-sensitive materials.
The rake vacuum dryer is a conduction heat transfer dryer. The material is not in direct contact with the heating medium, and is suitable for drying a small amount of mud-like and paste-like materials that are not resistant to high temperature and easy to oxidize. The moisture content is 15%~90%. The blades of the horizontal rake agitator in the dryer are made of cast iron or steel and are mounted on a square shaft with half of the blades oriented to the left and the other half to the right. The speed of the shaft is 7~8r/min, which is driven by a motor with a reduction box. At the same time, an automatic steering device is used to make the rotation direction of the shaft change the rotation direction of the agitator every 5~8min.
