The experimental spray freeze dryer is a product developed by our company after many experiments and combined with freeze drying technology in this field. The spray freeze dryer is compact, self-contained and can run without other facilities. Color large LCD touch screen operation, main components such as compressors, peristaltic pumps, heaters, nozzles and all original imports. Excellent equipment stability and high collection rate of products has been widely recognized and praised by customers.

Freeze spray dryer-experiment machine The range of application:

The spray freeze dryer is especially suitable for low temperature drying of materials with high temperature sensitivity, viscosity, active materials and high sugar content, such as natural product extracts, dairy products and biological preparations. Enzyme preparations, fruit juice, polymer materials and so on and suitable for universities, research institutes and food, pharmaceutical and chemical industry laboratories to produce micro particles of powder, for all solutions such as emulsion, Suspension has a wide range of applicability, suitable for the drying of heat-sensitive substances such as biological products, biological pesticides, enzyme preparations, etc.

Freeze spray dryer-experiment machine Main features:

1, color large touch screen operation, automatic control and manual control, Chinese and English panels, parameter liquid crystal display;

2, this machine will spray drying and vacuum freeze drying organic combination, the drying time is very short, The traditional vacuum freeze-drying time is greatly shortened, and the dried materials are powdery solids. The original biological and chemical properties of the spray-freeze-dried articles are basically unchanged and easy to preserve for a long time. After adding water, it can be restored to the form before freeze-drying and can maintain its original biochemical characteristics.

3, this machine adopts the refrigeration system of the built-in air-cooled condensing type totally closed compressor, which is quick to refrigerate, the temperature of the freezer is low, the adsorption capacity of water is strong, and the temperature is high. Vacuum display is digital, accurate and intuitive;

4, freeze-spray-dried articles are naturally heated air sublimation to maintain the safety of the sample;

5, the mainframe is equipped with a vacuum pump power plug, no additional power supply, easy to use, High safety;

6, vacuum connection using international standard clamps, convenient, reliable, flexible disassembly;

7, high degree of automation, stable performance, easy to operate, low noise;

8, compare with the traditional freeze-drying machine: Rapid freeze-drying of liquid materials with adherent wall and organic compounds (juice, Chinese medicine extract, etc.), and the dried finished product is in the state of particle, fluidity is good, the particle size can be adjusted within a certain range;

9, the special protection function, the fan does not start, Heater can not start;

10, imported compley oil-free air compressor, less noise than 50db
