Spray dryerProduct Introduction

Spray dryerIt is a type of continuous atmospheric pressure dryer. Spray the liquid material into a mist using special equipment, and dry it by contacting it with hot air. Used for drying some heat sensitive liquids, suspensions, and viscous liquids such as milk, eggs, tannins, and medicines. Also used for drying fuels, intermediates, soap powder, and inorganic salts.

working principle

After filtering and heating, the air enters the top air distributor of the dryer, and the hot air enters the drying chamber uniformly in a spiral shape. The feed liquid passes through the high-speed centrifugal atomizer on the top of the tower body, and (rotating) spray into extremely fine mist like liquid beads, which can be dried into finished products in a very short time in parallel with hot air. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the induced draft fan.

Product Features

The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated instantly, and the drying time is only a few seconds, which is particularly suitable for drying heat sensitive materials.

The product has good uniformity, fluidity, and solubility, high purity, and good quality. The production process is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go without the need for crushing and screening, reducing production processes and improving product purity. The particle size, bulk density, and moisture content of the product can be adjusted within a certain range by changing the operating conditions, making control and management very convenient.

structural characteristics

1. Drying speed block, generally only takes a few seconds to ten seconds, with the characteristic of instant drying;
2. To prevent material sticking to the inner wall of the dryer, a special structure is installed in the device to effectively prevent material sticking to the wall.
3. The finished product air delivery system separates the dried product from the hot and humid air in the system in a timely manner, effectively solving the possibility of moisture absorption or agglomeration of the dried product.
