High Speed Centrifugal Spray Dryer

Overview of centrifugal spray drying machine equipment
 The spray dryer is a drying process of pink products using thermal air (or other gas) to directly contact with the fog to obtain a drying process of pink products. The ingredients can be solution, milky liquid or suspension, or a melting or paste. Dry products can be made into powder, granular, hollow or ball -shaped as needed.

 The centrifugal spray dryer is hot air circulation, parallel, and centrifugal atomized dryer. The dry medium air is filtered through the initial and medium -efficiency air filters. After heating from the heater, enter the air distributor on the top of the dryer. The liquid material passes through the pump of the liquid and transported to the high -speed centrifugal atomizer on the top of the tower body. It is sprayed into a very subtle fog droplet under the action of centrifugal force, and it is contacted with hot air. Essence The finished product is continuously collected by the bottom of the dry tower and the whirlwind separator, and the fans are emptied after the exhaust dust removal.

The working principle of centrifugal spray drying machine
 The centrifugal spray dryer is mainly because the centrifugal force of the material is distributed by the centrifugal force of the atomizer of the high -speed rotating, and the material is distributed into a fog -shaped, and it is dry instantly with the hot air in the hot air distribution of the worm shell. Because the aggregate liquid is thrown out of the edge of the disc in a high -speed turntable (line speed above 110m/s), the diameter of the liquid liquid has a large diameter, so the dry tower requires a large diameter. At the same time, because the material is thrown out by the centrifugal force, the relative size of the fog is relatively uniform, and the moment of contact with the hot air is dry, the droplets are basically hollow powder, the particle size of the material is relatively uniform, but the particle size of the material Relatively small.

The centrifugal spray dryer is widely used in industry, such as chemical industry, food, medicine and other industries. As far as the spray -dry materials are concerned, there are a large difference in the nature of various raw materials, and the various products obtained have their own special requirements. Therefore, not only has its own special characteristics in the process, but also has its own particularity in the process arrangement, equipment structure, operation conditions, and even the subsidiary devices.

Features of centrifugal spray drying machine equipment
1. The spray drying speed is fast. After the liquid fluid is atomized, the surface area increases greatly. During the contact with the hot air, it can evaporate 95%to 98%of water in an instant. Dry.
2. The product has good uniformity, liquidity, and solubility. The higher the product purity, the better the quality.
3. Simplify the production process of spray dryers and convenient operation control. For liquids with a wet content of 40 to 60%(special materials can reach 90%), it can dry into powder products at one time. After drying, it does not need to be crushed and screened to reduce the production process and improve the purity of the product. The product particle size, loosening density, and water can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.

Spray dryer is the most widely used process in the formation process of liquid forming and drying industry. Suitable for slurry, such as solution, coriander, turbidal solution and other forms, spray small droplets in the hot air. The spray of the material is accelerated and atomized by accelerating the centrifugal force and gravity of high -speed centrifugal turntles. During the falling process of atomized liquid droplets, it is evenly mixed with the drying medium (hot air) to perform heat exchange and quality exchange, so that the moisture vaporization and evaporation process in the material. The spray dryer has the advantages of stable product nature, low degree of degeneration, continuous, automated, and large operating flexibility.
