High-Speed Centrifugal Spray Dryer
The high-speed centrifugal spray dryer is a drying device that uses a high-speed centrifugal atomizer to disperse materials into mist, fully contact with hot air, complete instant drying, and form finished powder products.
The application scope of the high-speed centrifugal spray:
1. Food Industry: whole milk powder, cocoa powder, milk replacer, egg white, egg yolk, instant tea, corn starch, etc.
2. Drugs: Chinese herbal extracts, yeast, vitamins, antibiotics, amylase, etc.
3. Plastic resin: AB, ABS lotion, resin, polyethylene, etc.
4. Chemical industry: pigments, catalysts, amino acids, etc.
5. Ceramics: alumina, ceramic tile materials, magnesium oxide, talcum powder, etc.
The working principle of our high-speed centrifugal spray dryer:
The feed liquid (which needs to be filtered) is sent to the high-speed rotating centrifugal atomizing disk (the rotating speed is 15000-25000 rpm, and the size of the atomizing disk is between 50 mm and 150 mm). Under the centrifugal force of the rotary disk, the feed liquid extends into a film on the rotating surface, constantly moves towards the edge, and has been atomized when leaving the border. The atomization of feed liquid is 20-60um droplets in size. The atomized droplets (with significantly increased surface area) exchange with hot air, and the drying is completed quickly, within 10-30 seconds. Some liquids even take 5 seconds. The temperature in the drying room drops sharply from top to bottom, and the materials will not be overheated, which is especially suitable for drying heat-sensitive materials. The temperature of discharged products is generally about 60 ℃. The spray dryer is usually used for drying liquid materials with a moisture content of 50% - 80%. Even if the moisture content of unique materials is up to 90%, they can be dried into a powder and granular products without concentration.
Although the high-speed centrifugal spray dryer is more expensive than the traditional spray dryer, it can handle many lotions, suspended lotions, and even some with viscosity. High-speed centrifugal spray desiccant can better preserve the original color, flavor, and taste of food when drying many foods.
Features of this high-speed centrifugal spray:
1. 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 especially suitable for drying heat-sensitive materials.
2. The product has good uniformity, fluidity, and solubility, and the finished product has high purity and good quality.
3. The production process is simplified, and the operation is convenient. The liquid with a moisture content of 40-60% (up to 90% for specific materials) can be dried at one time without crushing or screening after drying, reducing production processes and improving the purity of finished products. For finished products
The control and management of particle size, bulk density, and moisture are convenient.
