Spray drying tower principle use and advantages

The air is filtered and heated, and enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape uniformly. The liquid is sprayed into a very fine misty liquid droplet through a high-speed centrifugal atomizer at the top of the tower body. In parallel with hot air, it can be dried into a finished product in a very short time. The finished product is continuously discharged from the bottom of the drying tower and the cyclone, and the exhaust gas is discharged by the fan.

Spray drying tower use:

Spray drying is a widely used process in the liquid process forming and drying industry. Zui is suitable for the production of powdered, granulated or lumpy solid products from solutions, emulsions, suspensions and plastic paste liquid materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet exact standards.

The advantages of spray drying towers are as follows:

1. Various structurally complicated mechanical parts or other porous samples are washed and vacuum dried, leaving no residual material after complete drying;

2. For samples that are not easy to dry, such as powder or other granular samples, vacuum drying can effectively shorten the drying time;

3. Powdered samples are not easily blown or moved by flowing air compared to ordinary drying by air circulation;

4. Safer to use - completely eliminate oxides from thermal explosion under vacuum or inert conditions;

5. The vacuum environment greatly reduces the boiling point of the liquid to be repelled, so the vacuum oven can be easily applied to heat sensitive materials.
