Classification of laboratory spray dryers

The small spray dryer in Chuanyi Instrument Laboratory is applicable to the production of micro particle powders in universities, research institutes and food, pharmaceutical and chemical enterprise laboratories. It has broad spectrum applicability to all solutions, such as emulsion and suspension, and is suitable for drying heat sensitive substances, such as biological products, biological pesticides, enzyme preparations, etc. Since the sprayed materials are only exposed to high temperature when sprayed into aerosol particles, they are only heated instantaneously, which can keep the active ingredients of these active materials intact after drying.

Classification of spray dryer:
Chuanyi Instrument spray dryer can be roughly divided into four categories: high-temperature spray dryer, low-temperature spray dryer, frozen spray dryer and mini spray dryer. High temperature spray dryer and low temperature spray dryer are our main products.
1、 High temperature spray dryer
High temperature spray dryer can be divided into glass device and stainless steel device.
a. Advantages of glass devices: can directly observe the reaction process of materials; High cost-effectiveness.
Disadvantages of glass devices: not resistant to high temperatures; Glass material poses safety hazards.
b. Advantages of stainless steel equipment: strong thermal conductivity and high temperature resistance; Anti static and adsorption.
Disadvantages of stainless steel devices: poor intuitiveness and inability to see the material reaction process.
Note: Stainless steel devices can be divided into two types based on the content of organic solvents: conventional type and inert gas type.
When the organic content reachesIf it exceeds 60%, we need to introduce inert gas (nitrogen). Spray drying of materials can effectively avoid the reaction between active gas in the air and materials and explosion.

IILow temperature spray dryer
Low temperature spray dryer can dry materials in a vacuum environment by spray drying. It can lower the boiling point of water and make itSublimation at 60-80 ℃; It can also protect materials.
Advantages of low temperature spray dryer: it is applicable to heat sensitive materials, such as ethanol, Chinese herbal medicine and food that are not resistant to high temperature.
Disadvantages of low temperature spray dryer: materials with too high boiling point cannot be atomized or dried*.

IIIRefrigeration spray dryer

Refrigeration spray dryercan be-Freeze spray drying of materials is carried out under the ultra-low temperature environment of 60 ℃.

4、 Mini spray dryer
The mini spray dryer is reduced on the basis of the conventional small high-temperature spray dryer, which can be directly put on the test table for use. Low temperature spray dryer can also be customized into mini type according to user needs.
a. Advantages of the mini spray dryer: small machine, full functions, small space.
