High-speed centrifugal spray dryer is a new type of high efficiency drying process equipment, it can make the solution, emulsion, suspension and paste liquid materials, through spray drying into dry powder, fine, medium granular products. It has the advantages of high speed, high efficiency, less working procedure and saving manpower.
After air through the filter and heating device, into the drying chamber at the top of the hot air distributor, through the hot air distributor of hot air spiraling evenly into the drying chamber, at the same time by the pump delivered the material liquid in a drying chamber at the top of the centrifugal spray head, material liquid is sprayed into tiny fog droplets, and make the material liquid contact with the hot air specific surface area increased greatly. Small droplets and hot air flow sink, the water quickly evaporates in a very short time to be dried into granular products, at the bottom of the tower and cyclone separator capture, waste gas emissions to the outside world.
CHARACTERISTIC AND APPLICATION
1.the drying speed is fast. After the centrifugal spray, the specific surface area of the feed liquid is greatly increased, and 95-98% of the water can be evaporated instantly in the high temperature airflow, and the drying time is only a few seconds.
2.the use of concurrent flow spray drying form can make the droplet and hot air flow in the same direction, although the temperature of hot air is higher, but because the hot air into the drying room immediately contact with the spray droplets, indoor temperature drop will not dry the material excessive heat, so it is particularly suitable for the drying of heat-sensitive materials.
3.wide range of use. According to the characteristics of the material, it can be dried by hot air or molded by cold air. Large difference is very big features can use the production, the commonly used are: polymers and resins, dyes, pigments, glass, herbicides, insecticides, carbohydrates, milk egg products, slaughterhouse byproducts, blood and blood products, detergents and surfactants fertilizer, organic compound, inorganic compound, instant food, drugs, etc.
4.because the drying process is completed in an instant, the particles of the product basically keep the approximate spherical droplets, with good dispersion, fluidity and solubility.
5. Simplified production process, convenient operation and control. Spray drying is usually used for the solution with 40-60% wet product content. Even if the content of special materials is up to 90%, it can be dried into powder products at one time. After most products are dried, there is no need for crushing and screening, which reduces the production process, simplifies the production process and improves the purity of the products. The particle size, bulk density and moisture of the product can be adjusted and controlled by changing the operating conditions within a certain range. It's easy to manage.
6.In order to prevent the material from being polluted and prolong the service life of the equipment, all the parts in contact with the material are made of stainless steel. In order to facilitate the operation, the control system adopts integrated operation.
