What should you pay attention to when selecting spray drying equipment? This starts with what the spray dryer is used for. Spray drying equipment is a drying method that uses an atomizer to disperse the raw material liquid into mist droplets to obtain the product. It can be understood from the literal meaning that you need to pay attention to the atomizer when selecting spray drying equipment. Atomizer is the main component of spray drying equipment, so what atomizers are currently used?

First, air flow atomizer: uses compressed air or steam to spray from the nozzle at a very high speed (greater than or equal to 300m/s). The friction force generated by the same speed difference between the gas and liquid causes the material and liquid to split into mist. drop.

Second, the pressure atomizer uses a high-pressure pump to obtain high pressure for the liquid. When the high-pressure liquid passes through the nozzle, the pressure energy is converted into kinetic energy and is sprayed out at high speed to disperse into droplets.

Third, rotary atomizer: The liquid material is thrown out by centrifugal force in the high-speed turntable (circumferential speed 90-160m/s) and atomized.
