Vacuum Dryer Vacuum Dryer is a conductive heat transfer dryer. The material is not directly in contact with the heating medium, and is suitable for drying a small amount of mud-like or paste-like materials which are not resistant to high temperature and easy to be oxidized, and the water content is 15% to 90%. The blades of the horizontal jaw mixer in the dryer are made of cast iron or steel and are mounted on a square shaft with half of the blades to the left and the other half to the right. The shaft speed is 7~8r/min, which is driven by the motor with gearbox. At the same time, the automatic steering device is adopted to change the rotation direction of the shaft and change the rotation direction of the agitator every 5~8 minutes.
The plate type vacuum dryer plate vacuum dryer is also called the disk type vacuum dryer. It has been introduced in the drying monograph published in Japan. China's Shanghai, Shijiazhuang and other places have been successfully developed. It is a multi-layer fixed hollow heating disc (also known as a loading tray), which is developed on the basis of intermittently stirring and conducting the dryer, and has been comprehensively improved. Conductive-based drying unit.
Low-temperature belt continuous vacuum dryer Low-temperature belt continuous vacuum dryer is a new concept of high-efficiency energy-saving drying equipment in Chinese medicine after repeated comparison of the advantages and disadvantages of conventional spray drying and freeze-drying. In the drying of products in western medicine, chemical, food, health care products, etc., spray drying is beneficial to the cost, but the solubility of the product. The original taste and the shape of the powder have large defects, and the products with slightly higher viscosity and heat sensitivity requirements are I can't do anything about it. Conventional freeze-drying results in excellent product solubility and high quality products, but the yield is too low and expensive.
The various process indexes of the low-temperature continuous vacuum dryer are just between the above two kinds of equipments, which can make the inside of the dried product porous and loose, retain the original material properties of the product, and have a good appearance. Meet the processing requirements of a large part of heat sensitive materials.
The low-temperature continuous vacuum dryer breaks through the technical problem of continuous feeding and discharging under vacuum, and the static drying is successfully converted into dynamic drying. The production cost of the dried products is greatly increased while the production cost is reduced.
The low temperature continuous vacuum dryer is especially suitable for the drying of high viscosity, high fat, high sugar and other materials which are difficult to solve by spray drying and vacuum oven. And can maintain the stability and consistency of the product batch.
Technical features:
1. Continuous feeding and discharging are achieved under vacuum, and the amount of feed can be freely set as needed.
2. The heating system can take various forms such as steam, hot water and electric heating to heat transfer oil heating.
3. The drying temperature is arbitrarily adjusted from 25 ° C to 80 ° C, and continuous discharge is started after 20 minutes to 60 minutes until batch completion.
4. The track is made of Teflon material, which is stable, reliable and evenly heated. The track speed can be adjusted arbitrarily by 2 to 5 layers, which can be determined according to the user's production requirements.
5. A variety of fabrics are available to accommodate the drying of liquids, extracts, powders and granules.
6. Equipped with an automatic pulverizing system under vacuum conditions, the number of dry granules can be arbitrarily selected according to the user's requirements.
7. Equipped with CIP in-place cleaning system, automatic cleaning is fast and convenient.
8. The high-quality vacuum unit is selected and carefully designed to have a continuous large-capacity pumping rate and a stable vacuum.
9. Low energy consumption, no waste, no noise.
10. Fully compliant with GMP certification requirements.
The main advantage:
· The whole process is automated, pipelined, continuous, and programmed.
· The drying process is completed under vacuum and low temperature conditions, and the heat sensitive materials are invariant and have no chance of dyeing bacteria.
· Suitable for drying all kinds of difficult materials.
· Material dryness (water content) is adjustable.
• Energy consumption is only one-third that of a centrifugal sprayer of the same output.
· It adopts PLC touch screen operation control and has continuous protection device.
·The machine is reasonable in design, compact in structure, convenient to install and debug, and suitable for placement under most working conditions.
Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement. The minerals of the human body are not balanced, and health products have great advantages in fixed health functions.
About mechanical classification and technical characteristics of vacuum dryer
Mechanical classification Double cone rotary vacuum dryer Double cone rotary vacuum dryer is suitable for the concentration, mixing, drying and low temperature drying of powdery, granular and fibrous materials in chemical, pharmaceutical and food industries (such as biochemical products). It is more suitable for drying of materials which are easy to oxidize, volatile, heat sensitive, toxic materials and materials that do not allow damage to crystals. The belt/chain two-stage elastic connection method makes the equipment run smoothly. The specially designed process fully reflects the good concentricity of the two shafts. The heat medium and vacuum system use reliable mechanical seals or American technology rotary joints. The machine can be steplessly regulated and thermostat controlled. The heat medium is available from high temperature heat transfer oil, medium temperature steam and low temperature hot water. When drying viscous materials, the “copy board†structure will be specially designed for you in the tank.
