QFN-FSD-2 laboratory spray freeze dryer is an original product carefully developed by Shanghai Qiaofeng Industrial Equipment Co., Ltd. combining spray drying technology and vacuum freeze drying technology. Since the product came out, we have been functional, performance and easy to use. The performance is steadily improved. The maximum processing capacity of each batch of spray freeze dryer is ≥2L/time, and the drying time of some materials does not exceed 5 hours. The processing capacity of each batch of customized spray freeze dryer reaches 5000ML/time and 10L/time. A series of spray freeze-dried products from laboratory, small test to pilot test have gradually formed.
Scope of application:
The laboratory freeze spray dryer is suitable for low-temperature drying of heat-sensitive, viscous, active materials and materials with high sugar content, such as natural Chinese herbal medicine extracts, dairy products, biological preparations, enzyme preparations, fruit juices, and polymer materials Wait.
main feature:
The laboratory spray freeze dryer organically combines spray drying and vacuum freeze drying. The drying time required is extremely short. The drying time of some materials does not exceed 5 hours (2000ML/time), which greatly shortens the traditional vacuum Freeze-drying time, and the dried material is a powdery solid, the original biological and chemical properties of the spray-freeze-dried items are basically unchanged, and it is easy to store for a long time;
The laboratory spray freeze dryer adopts an air-cooled condensing fully enclosed compressor refrigeration system, which has rapid cooling, low temperature of the freezer, strong moisture absorption capacity, and both temperature and vacuum display are digital, accurate and intuitive;
Freeze spray-dried items are sublimated by natural air heating to maintain the safety of samples;
The main unit is equipped with a vacuum pump power plug, no need to connect to a power supply, easy to use;
The vacuum connection adopts the international standard clamp, which is convenient and reliable;
Stable performance, easy operation, low noise;
The laboratory spray freeze dryer is compared with the traditional freeze dryer: it can quickly freeze dry liquid materials that are easy to stick to the wall and contain organic substances (juice, Chinese medicine extract, etc.), and the dried product is in the state of granules with good fluidity. The particle size is adjustable within a certain range.
technical parameter:
1. Maximum processing capacity: ≥2L/time
2. Operating temperature: ≥-60 degrees
3. Drying process: freezing-spraying-sublimation drying
4. Atomization method: ultra-fine frozen spray airflow atomizer (QFN-2-1)
5. The entire atomization mechanism, without any plastic gaskets, without any motors, has a longer service life and is easy to maintain
