Stainless steel industrial centrifugal dryer

Centrifugal spray dryers and spray drying towers are widely used processes in liquid forming and drying industries. They are applicable to the production of powdered solid products using suspensions, emulsions, emulsions and pasty liquid raw materials as raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and powder shape of the finished powder all meet the standards, the spray dryer is an ideal drying process. Key points of the spray drying process: 1. Contact between hot air and droplets: When sufficient hot air enters the spray drying chamber, the flow direction and Angle of the hot air must be considered. Whether it is parallel flow, counter-flow or mixed flow, it is necessary to ensure full contact with the droplets to achieve sufficient heat exchange. 2. Atomization: The atomization system of the spray dryer must ensure a uniform distribution of droplet sizes, which is of vital importance. This is directly related to the pass rate of product quality. 3. Design of pipe angles and cone angles: We have nearly a thousand production experience data of spray drying equipment and can share them with you.

1: Fast spray drying speed. After the liquid is atomized, its surface area increases significantly. During the process of contact with hot air, 95% to 98% of the moisture can evaporate instantly. The drying time only takes a few seconds, making it highly suitable for drying heat-sensitive materials. 2. The product has good uniformity, fluidity and solubility. The higher the purity of the product, the better its quality. 3. The production process of the spray dryer is simplified and the operation control is convenient. For liquids with a moisture content of 40-60% (up to 90% for liquid materials), they can be dried into powder products in one go. After drying, there is no need for crushing or screening, which simplifies the production process and improves the purity of the product. By changing the operating conditions, the particle size, bulk density and moisture content of the product can be adjusted within a certain range, which is convenient for control and management.
