Laboratory benchtop spray dryer

Laboratory Small Spray DryerTechnical Parameters  
1. Maximum drying capacity: 1.0 kg water/hour; Drying time: 1.0–1.5 seconds; Maximum air flow rate: 35 m³/h.  
2. Maximum compressed air flow rate: 3000 L/h (standard conditions);  
3. Maximum temperature: 220°C; Heating temperature control accuracy: ±2°C.  
4. LED digital display: inlet temperature; outlet temperature; exhaust fan air volume; peristaltic pump speed.  
5. Nozzle orifice diameter: 0.7 mm; Power supply voltage: 220V/50Hz ±10%; Current: 14A; Power: 2900W. 

Main Features 
1. Suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc. Since the sprayed material is only exposed to high temperature when atomized into fine particles, it is only heated instantaneously, thereby preserving the active components of these materials after drying. The feed rate can be adjusted via the feed pump, with a minimum  
2. The entire spray drying process is carried out in glass apparatus, allowing operators to observe clearly and make timely adjustments if any issues arise. The inner walls of the glass apparatus are treated with antistatic coating, so under normal drying conditions, the dry powder will not adhere to the inner walls.  
3. For spray drying of certain pharmaceutical products, to achieve sterility, high-temperature hot air can be used for sterilization before use. An air inlet filter is installed to maintain air cleanliness.  
4. The finished dry powder after drying has relatively uniform particle size, with over 90% of the powder falling within the same particle size range. The unit is equipped with a nozzle cleaner (needle), which automatically clears blockages when the nozzle becomes clogged.  
5. Both the hot air temperature and flow rate are displayed on a liquid crystal display. All adopted parameters are shown on the LCD.

Small-Scale Spray DryerIntroduction 

The laboratory-scale Model B-290, manufactured by BUCHI Laboratory Instruments, Switzerland,Small-Scale Spray Dryerhas been purchased by a considerable number of domestic users and has been performing well. It is primarily used for drying food products, pharmaceuticals, biological pesticides, dairy products, and various organic extract solutions. Its applications are extensive, and compared with spray dryers of other brands both domestically and internationally, its advantages are as follows: 
 
  Suitable for drying heat-sensitive materials such as biological products, biological pesticides, enzyme preparations, etc. Since the sprayed material is only exposed to high temperature when atomized into fine particles, it is only heated instantaneously, thereby preserving the active components of these materials after drying.  

  The feed rate can be adjusted via the feed pump, with a minimum sample volume of 50 ml.
