QFN-VSD-1 experimental vacuum spray dryer (QFN-VSD-1 ultra low temperature spray dryer) is the innovative product of Shanghai Qiao Feng Industrial Equipment Co., Ltd. in the field of spray drying for 12 years. It is the most effective way of fast drying of heat sensitive materials. It has realized the instant drying of the material at low temperature (the lowest 50 degrees), and it is a thermosensitive material. To provide a very convenient extremely safe drying method, such as enzyme bacteria and other biological products, Chinese herbal medicines containing natural extracts with high sugar, high polymer material heat, heat gasification material and so on.

Technical features:

1) QFN-VSD-1 experimental vacuum spray dryer spray drying the drying process in a vacuum environment, greatly reduce the drying temperature, solves the problem of dry heat sensitive material containing sugar material biological material spray. It
2) color touch screen operation: heating temperature PID constant temperature control, peristaltic pump feeding speed can be adjusted at any time. It
3) the spray head of the QFN-VSD-1 experimental vacuum spray dryer is a concentric spray head. When the atomization ensures without any eccentricity, it can be sprayed to the side of the bottle wall, and the spray head can move up and down after installation, in order to adjust the atomization position to improve the spray drying effect; two the atomization structure of the fluid spray, the precision stainless steel material is used for precision system It has compact design, no auxiliary equipment, and convenient use. It
4) the QFN-VSD-1 experimental vacuum spray dryer adopts the noise reduction and shock absorption system developed by our department to effectively reduce the noise of vacuum pumps and air compressors. It
5) in order to meet the needs of the user to adjust the parameters in the experimental range, the real-time regulation of PID temperature control technology in the design of drying temperature control, the temperature control of all temperature accurately, the heating temperature control accuracy of plus or minus 1 DEG C. It
6) the feed quantity can be adjusted by feeding peristaltic pump, and the rated capacity is 1500mL/H.

Technical parameters:

1. The whole machine is made of stainless steel and atomized by two fluid atomization.
2. Spray head for concentric atomization spray head, ensure no eccentric to spray to the bottle wall side, after the installation of the spray head can move up and down, in order to adjust the position to improve the atomization spray drying effect;
3. The rating of the rated material: 1500mL/H;
4. The minimum sample size is 50mL (depending on the solid content of the material).
5. Real time control of PID thermostat control technology, heating and temperature control accuracy: + 1 C;
6. Nozzle caliber: 0.5mm, 0.7mm, 1mm, 1.5mm, 2mm optional, and can be customized according to customer requirements.
7. The power of the whole machine: 6KW/380V;
8. At low temperature (50 DEG C) under the conditions of complete instantaneous spray drying (1500ML/H), moisture content after drying is lower than 1% in the dry condition, easy oxidation, volatile, heat sensitive substances can maintain the chemical structure and biological activity;
9. The vacuum degree is -0.05 to 0.08MPA;
10. Color LCD touch screen operation control, full Chinese operation interface.
