Small spray dryer
One: Picture of QFN small spray dryer:
Small spray dryer, also known as spray dryer, laboratory spray dryer, is mainly used for laboratory small sample drying experiment.
Two: Application description of small spray dryer:
QFN brand small spray dryer is suitable for the production of micro-particulate powder in universities, research institutes and laboratories of food, pharmaceutical and chemical companies. It has wide applicability to all solutions such as emulsions and suspensions. It is suitable for drying heat-sensitive substances such as biological Products, biological pesticides, enzyme preparations, etc. Because the sprayed material is only subject to high temperature and instantaneous heating when sprayed into a mist, these active materials maintain their active ingredients unchanged after drying.
Specifically used in the following fields: beverage flavors and pigments milk and egg products plant and vegetable extracts pharmaceutical synthesis heat-sensitive substances plastic polymers and resin fragrances blood products ceramics and superconductor biochemical products dye soap and detergent food binder oxide bone powder And tooth powder, etc.
Three: Main features of small spray dryer:

5 There is a nozzle cleaner (through needle), which will be automatically cleared when the nozzle is blocked, and the frequency of the needle can be adjusted automatically.
6 Shutdown protection function: Just press the stop button during shutdown, the machine will stop running immediately except for the fan, to ensure that the device will not burn out due to misoperation (forced shutdown of the fan).
7 The spraying, drying and collecting system is made of transparent high-quality borosilicate heat-resistant glass material, so that the drying process can be carried out in a pollution-free environment.
8 Built-in imported oil-free air compressor, the particle diameter of the powder spray is normally distributed, the fluidity is very good, the noise is very low, less than 60db.
9 The atomization structure of the two-fluid spray, the whole machine is made of high-quality stainless steel material, the design is compact, and no auxiliary equipment is required.
10. The design of dry temperature control adopts real-time control PID constant temperature control technology, so that the temperature control in the whole temperature zone is accurate, and the heating temperature control accuracy is ± 1 ℃.
11 In order to keep the sample pure, equipped with air inlet filter.
12 The feeding volume can be adjusted by feeding peristaltic pump, and the minimum sample volume can reach 50ml.
13 The particle size of the finished dry powder after drying is relatively uniform, and more than 95% of the dry powder is in the same particle size range.
14 For viscous materials, there is a nozzle cleaner (through needle), which will be automatically cleared when the nozzle is blocked, and the frequency of the needle can be adjusted automatically.

Five: Working principle of small spray dryer:
The small spray dryer sprays the material into mist droplets and disperses them in the hot air by spraying. The materials and the hot air contact each other in the form of cocurrent, countercurrent or mixed flow, so that the water quickly evaporates to achieve the purpose of drying.
With this spray drying equipment drying method, unit operations such as concentration, filtration, and crushing can be omitted, and granular products of 30 to 500 μm can be obtained. And the drying time is short, the general drying time is 5 ~ 30s. The spray dryer is suitable for the drying of highly heat-sensitive materials and materials that are easily dispersed during the concentration of the material liquid. The product has good fluidity and instant solubility.
