Spray dryer professional processing:
Spray dryer is a device that can complete drying and granulation at the same time. It is widely used in drying heat-sensitive liquids, suspensions and viscous liquids, such as milk, egg liquid, medicinal materials, extracts, inorganic salts, etc. Its working principle is to spray the liquid material into mist through a high-pressure nozzle, contact with hot air, and evaporate the water quickly to obtain dry powder or particles.
Spray dryers are suitable for a variety of fields, including but not limited to:
Food industry: used for drying heat-sensitive liquids such as milk and egg liquid.
Pharmaceutical industry: used for drying materials such as medicinal materials and extracts.
Chemical industry: used for drying fuels, intermediates, soap powder and inorganic salts.
Spray dryers are mainly of the following types:
Centrifugal spray dryer: The liquid is thrown into mist through a high-speed rotating centrifugal disk and dried in contact with hot air.
Pressure spray dryer: The liquid is sprayed into mist through a high-pressure nozzle for drying.
Chinese medicine extract spray dryer: specially used for drying Chinese medicine extract.
Technical parameters and performance characteristics of spray dryer:
The technical parameters of spray dryer include processing capacity, hot air temperature, feed speed, etc.
Its performance characteristics include:
High efficiency and fast speed: It can complete the drying process in a short time.
Easy to operate: By adjusting the pressure, flow rate and size of the spray hole of the liquid pump, particles of the required size can be obtained.
Wide range of application: It is suitable for drying and granulating a variety of liquid materials.

Note: The amount of water evaporation is related to the characteristics of the material and the hot air inlet and outlet temperatures. When the outlet temperature is 90℃, the water evaporation curve is shown in the figure above (for model selection reference). As the product is constantly updated, the relevant parameters will change without prior notice.
