Spray Dryer Equipment:
The spray dryer is widely used in chemical, food, pharmaceutical industries. It can convert the liquid, suspension, emulsion into powder product. It can keep the product color, flavor and quality. The heat source can be electric, steam, natural gas, coal and diesel.
The spray drying is the widest used technology in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquid and pumpable paste states. Therefore, when the particle size and distribution of the final products, their residual water contents, the stocking density and the particle shape meet the precision standards, the spray drying is one of the most desired technologies.
Spray dryer features
1, High speed of drying. After the spraying of he material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.
2, It is especially suitable for drying the heat sensitive materials. It`s final products own the good uniformity, mobility, dissolving capacity. And the final products are high in purity and good in quality.
3, The production procedure is simple and the operational control is easy. The liquid with the moisture contents 40-60%(for special materials, the contents may reach 90%) can be dried into power or particle products once a time. After the drying, there is no need for smashing of sorting, so as to reduce the operation procedures in the production and enhance the purity. The product particle diameter, looseness and water contents can be adjusted through changing the operation condition in a certain scope.
