Product description

Spray drying is a method of rapid drying of hot gases to produce a dry powder from a liquid or slurry.This is the preferred drying method for many heat-sensitive materials such as food and medicine.

The liquid material is pumped by a single pump into the top mounted disc atomizer, atomized into fine droplets in the drying chamber.Heating clean hot air while blowing into the air distributor.Evenly distributed, rotating hot air in full contact with the droplets heat transfer.Water droplets are dried into powder within seconds, then sucked into the cyclone, and then discharged through the exhaust fan.

LPG series spray dryer is widely used in pharmaceutical, chemical, food and other industries, used to dry liquid materials into fine powder.

main features

1) particle size control: through the atomization of the liquid feed and the design of the hot air port, you can easily control the drying particle size.This spray dryer can generally produce an average particle diameter of 30-500 microns bell-shaped distribution.

2) product evaporative cooling: heat and mass transfer during drying occurs in the air and vapor film around the droplets.The protective layer of the Steam keeps the particles at a saturation temperature.As long as the particles are not“dry”, evaporation is still taking place, the temperature of the solids will not be close to the outlet temperature of the dryer.

3) short residence time: Liquid atomizing gas surface area of the residence time is short, depending on the scope of use, the residence time between 3-10 seconds, spray drying can be achieved without thermal degradation.

4) the flow characteristics of the dried product:most spray-dried particles are spherical,which provides the flow characteristics of the fluid.This makes many downstream operations,such as packaging, pressing, filtration and processing easier and less costly.
