Centrifugal spray dryer

High-speed centrifugal spray dryer

Overview:

LPG series high-speed centrifugal spray drying is the most widely used process in liquid process formation and drying industries. It is most suitable for producing powdered and granular products from emulsion, suspension solution, and pumpable paste liquid raw materials. When the physical property indicators of the product, such as particle size distribution, moisture content, bulk density, and particle shape, are strictly required, spray drying is a very suitable process. Our factory's design and manufacturing capabilities for large centrifugal spray dryers have reached a diameter of 11 meters and a spray liquid volume of 10 tons per hour. Our factory will design different configurations based on the characteristics of different materials.

Working Principle:

The feed liquid is fed into the centrifugal atomizer installed at the top of the drying tower, where it is sprayed into extremely small droplets by the high-speed rotating atomizing disc. Simultaneously, hot air is distributed in a spiral pattern and evenly spread throughout the drying tower via the hot air distributor installed at the top. The two streams fully and concurrently contact each other, causing rapid evaporation of water. The material is dried into finished products in a very short period of time. The finished products are continuously discharged from the bottom of the drying tower through a cyclone separator (bag filter), while the exhaust gas is evacuated by a fan.

Features:

▲Fast drying speed, suitable for heat-sensitive materials;

▲The product is spherical particles with uniform particle size, good fluidity, good solubility, high purity, and good quality;

▲The product is formed in one step without the need for crushing and screening, and the process control is automated, making the production process simple and convenient to operate;

The particle size, bulk density, and moisture content of the product can be adjusted within a certain range;

▲With a wide range of applications, it can be used for both hot-air drying and cold-air granulation according to the characteristics of the material, demonstrating strong adaptability to different materials.
