Laboratory Mini Lab Spray Dryer
Spray drying technology is a drying method with rapid development and wide application range in the drying field. It is widely used in many industries such as food, pharmacy, petroleum, chemical industry, bioengineering, new materials, new energy, etc.
Advantages of spray drying:
The drying conditions remain constant, and the characteristics of the dried sample remain constant
◆ High flexibility in experimental operations and wide range of sample processing capacity
The experimental process is continuous, stable, and controllable throughout the entire process
◆ Wide range of applicable samples, suitable for both thermosensitive and non thermosensitive materials; Drying of aqueous solutions and organic solvents
The raw material liquid can be a solution, emulsion, paste or melt, etc.
The small spray dryer uses a two fluid nozzle to disperse the sample solution into droplets. The droplets in the drying tower directly contact with the hot air to take away the moisture (or other liquids) in the sample, so as to achieve the purpose of drying. The waste gas is separated from the sample powder through the cyclone separator. The sample powder is retained in the main receiving bottle, and the waste gas is discharged through the outlet filter.

Working principle
The high-performance spray dryer is widely applicable to all solutions, such as emulsions and suspensions. It can also dry some heat sensitive substances, such as biological products, biological pesticides, enzyme preparations, food, etc. Thermally sensitive substances evaporate instantly in the drying tower, and the surface temperature of the droplets is not high, so these active materials can still maintain their active ingredients unchanged after drying.
