Spray dryer design introduction
The spray dryer is designed to perform both drying and granulation equipment. According to the process requirements, the pressure, flow rate and orifice size of the liquid pump can be adjusted to obtain the desired spherical particles in a certain proportion. The spray dryer is a type of continuous atmospheric dryer. The liquid material is sprayed with a special device to be dried in contact with hot air. Used to dry some heat sensitive liquids, suspensions and viscous liquids, as well as dry fuels, intermediates, soap powders and inorganic salts. Generally, it includes an electric blast drying oven, a vacuum drying box, a high-speed centrifugal spray dryer, and a sterile spray dryer.
Spray dryer design characteristics
1.The drying speed is fast, the surface area of the liquid is greatly increased after atomization, and in the hot air flow, 95%-98% of the water can be evaporated instantaneously, and the drying time is only a few seconds, which is especially suitable for drying the heat sensitive material.
2.The product has good uniformity, fluidity and solubility, and the product has high purity and good quality.
3.Simplified production process and convenient operation and control. For liquids with a moisture content of 40-60% (up to 90% of special materials), it can be dried into a powdered product at one time, which is convenient for control and management.
