No one knows more about spray drying. Our expertise has been acquired for almost a century, during which time we have designed and supplied more than 10,000 drying equipment around the world and become more tested by customers. A BLPG closed loop centrifugal spray dryer is individually designed to meet your specific needs. Our vast drying knowledge within our field of expertise and our technology are entirely at your disposal. In short, we can put our ideas into practice and realize a high-quality powder designed to meet your specific requirements, performance as well as precise characteristics.
The advantages of BLPG closed-circuit centrifugal spray dryer mainly focus on the following points:
(1) The drying speed of the spray dryer is fast. After the material liquid passes through the spray, the surface area is large. In the high-temperature air flow, it can evaporate in an instant.
(2) The temperature of the droplets during the drying process of the spray dryer is not high, and the product quality is better. Spray drying uses a wide temperature range (80-800 degrees). Even if high-temperature hot air is used, the exhaust temperature will not be very high. In the early stage of drying, the temperature of the material does not exceed the wet bulb humidity of the surrounding hot air, and the quality of the dried product is better. . For example, protein changes, vitamin loss, oxidation and other defects are not easy to occur. The quality of heat-sensitive materials, biology and medicine can basically be close to the standard of drying under vacuum.
(3) The product of the spray dryer has good dispersibility, fluidity and solubility. Because the drying process is completed in the air, the product can basically maintain a spherical shape near the droplet, and has good dispersibility, fluidity and solubility. Solubility.
(4) The production process of BLPG closed-circuit centrifugal spray dryer is decomposed, and the operation is convenient. Spray drying is generally used to deal with solutions with a moisture content of 40%-60%. Special materials can be used without concentration even if the moisture content is as high as 90%. Once dried into a powdered commodity. Most of the products do not need to be crushed and screened after drying, thus reducing the production procedures and simplifying the production process. The particle size, bulk density and water content of the product can be adjusted by changing the operating conditions within a certain range, and the control and management are very convenient.
(5) Avoiding pollution and improving the production environment Because spray drying is carried out in a closed drying tower, this prevents dry products from flying in the workshop. For materials with toxic gas and odor, the production process of closed circulation system can be adopted to incinerate the toxic gas and odor, so as to avoid air pollution and improve the production environment.
(6) Closed-loop centrifugal spray dryer The spray dryer is suitable for continuous large-scale production. Spray drying can meet the requirements of large-scale industrial production. After continuous discharge of dried products, it can be transported by cooler and wind in post-processing. Form a continuous production line.
