QFN-FSD-1 laboratory spray freezing dryer is an original product developed by Shanghai Qiao Maple Industrial Equipment Co., Ltd. combined with spray drying technology and vacuum freeze drying technology. Since the product came out, we have been steadily improving in function, performance and usability. At present, every batch of standard YC-3000 spray freeze dryer Maximum treatment capacity is 2000ML/ times, the drying time is less than 6 hours, the custom type spray freeze dryer batch processing volume reached 5000ML/ times and 10L/ times, gradually formed from the laboratory test, to test a series of spray freeze drying products.

Scope of application: 
QFN-FSD-1 laboratory freeze spray dryer is suitable for heat sensitive, viscous, active materials and low temperature drying of materials with high sugar content, such as natural product extract of Chinese herbal medicine, dairy products, biological agents, enzyme preparations, fruit juice, polymer materials and so on.

Main features:

1. The QFN-FSD-1 laboratory spray freeze drying machine combines the two people with the spray drying and the vacuum freeze drying. The drying time is very short and the drying time is not more than 5 hours (2000ML/ times). The traditional vacuum freeze drying time is greatly shortened, and the dried material is powdery solid after drying, and the drying is frozen by spray freeze drying. The original biological and chemical properties of the articles are basically unchanged, and they are easy to preserve for a long time.
2. QFN-FSD-1 laboratory spray freeze dryer uses air-cooled condensing type full closed compressor refrigeration system, rapid cooling, freezing for low temperature, moisture adsorption capacity, temperature and vacuum are digital display, accurate and intuitive;
3. The refrigerated spray dried articles were heated by natural air heating to maintain the safety of samples.
4. The main engine is equipped with a vacuum pump power plug without additional power supply, which is convenient to use.
5. The international standard clamp is adopted for vacuum connection, which is convenient and reliable.
6. The performance is stable, the operation is simple and the noise is low.
7. QFN-FSD-1 laboratory spray freeze drying machine compared with the traditional freeze drying machine: liquid material can easily stick wall, organic fast freeze drying (extract juice, etc.), and the dried products were particle state, good fluidity, the particle size can be adjusted in a certain range.

Technical parameters: 
1) color LCD touch-screen parameters display: drying chamber temperature / peristaltic pump speed / fan frequency / needle frequency / drying chamber pressure;
2) processing capacity: 2000ml/ times (drying time is less than 6 hours, in addition, Shanghai Joe Feng Industrial Equipment Co. Ltd. has developed 3L/ times, 5L/ times, 10L/ times of spray freeze dryer, the amount of processing welcomed the consultation);
3) the spray head is a new concentric spray head. The atomization is not eccentric, and the spray head can move up and down, which is conducive to the adjustment of the best atomization process.
4) spray freezing temperature: <-15 C;
5) cold well temperature: less than -60 C;
6) the power of the vacuum pump is <2KW;
7) limit vacuum pressure <20Pa (no-load);
8) spray pressure: 2-5BAR (spray pressure adjustable);
9) air compressor output of air compressor: 4.2M3/h;
10) cold wind volume: 5.5M3/min;
