1, BH series centrifugal spray dryer - equipment overview

Centrifugal spray dryers are the most widely used processes in the liquid forming process and the drying industry. Spray drying is to use a nebulizer to disperse the raw material liquid into droplets. The drying medium air is filtered by the primary and intermediate effect air filters, and then sucked by the air blower according to the operation instruction and then heated by the heater through the hot air distributor of the high efficiency filter to enter the spray drying. Main tower. The liquid material passes through the peristaltic pump according to the operation instruction, enters the high-speed rotating centrifugal nozzle, and is dispersed into small droplets under the action of centrifugal force. In the spray-drying main tower, the small droplets are in full contact with the hot air, heat-exchanged along its specific path, and then dried to form a product, which is then separated by a cyclone, solid materials are collected, and the gaseous medium is filtered and discharged. .

The centrifugal spray dryer is suitable for use in suspoemulsion, solution, emulsion and paste liquid raw materials, and the dried product can be formed into powder, granules, hollow spheres or agglomerates as needed. Therefore, high-speed centrifugal spray drying is an ideal production process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product meet the exact standards.

2, BH series centrifugal spray dryer - equipment features

2.1, centrifugal spray dryer speed, after the atomization of the liquid, the surface area is greatly increased, in the process of contact with hot air, can instantly evaporate 95% -98% of water, drying time is only a few seconds, especially suitable for Drying of heat sensitive materials.

2.2, the product has good uniformity, fluidity and solubility, the diameter of the droplet particles can be slightly adjusted, the hot air is evenly distributed, eliminating the phenomenon of overturning and sticking. In a high temperature gas stream, the temperature of the surface wetting material does not exceed the wet bulb temperature of the drying medium, and the final product temperature is not high due to rapid drying. Therefore, spray drying is particularly suitable for heat sensitive materials.

2.3, centrifugal spray dryer production process is simplified, easy to operate and control. For liquids with a moisture content of 40-60% (up to 90% of special materials), the liquid can be dried into a powder product at one time. The particle size, bulk density and moisture of the product can be adjusted within a certain range by changing the operating conditions to meet each Quality indicators of the product, such as particle size distribution, product shape, product properties (excluding dust, fluidity, wettability, instant solubility), color, aroma, taste, biological activity of the product and the moisture content of the final product.
 
2.4, automatic control of production process, easy to operate, reliable system. The solution can be made into a powder product directly in a drying tower. Also. Spray drying is easy to mechanize and automate, reducing dust and improving the working environment.
