Shanghai Bilang spray dryer working principle introduction
Spray dryer works: There are three types of spray dryers: pressure spray dryer, centrifugal spray dryer, airflow spray dryer. Spray dryer principle: Spray drying is a drying method in which a raw material liquid is dispersed into a mist by an atomizer, and a mist is dried with a hot gas (air, nitrogen or superheated steam) to obtain a product. The spray-dried raw material liquid may be a solution, an emulsion, a suspension, or a melt or a paste liquid. The dried product can be made into powder, granules, hollow spheres or pellets as needed. 4. The atomization of the liquid to disperse the liquid into droplets is a key component of spray drying. Pressure spray dryer principle: A pressure atomizer is used: a high pressure pump is used to obtain a high pressure of the liquid, and when the high pressure liquid passes through the nozzle, the pressure energy is converted into kinetic energy and dispersed as a droplet at a high speed. Airflow spray dryer principle: Airflow atomizer: using compressed air or steam to eject from the nozzle at a very high speed (≥300 m/s), the friction generated by the difference in velocity between the gas and liquid phases causes the liquid to split into droplets. . Principle of centrifugal spray dryer: Rotary atomizer is used: the liquid is atomized from the edge of the disc by centrifugal force at a peripheral speed of 90-160 /ms.
