Centrifugal spray drying is a core process in the liquid process forming and drying industry and is widely used to produce powdery, granular or bulk solids. Spray drying is an ideal solution when liquid raw materials to be processed include solutions, emulsions, suspensions and pumpable pastes.
Due to its special atomization method and instantaneous evaporation characteristics, spray drying shows extremely high efficiency and effectiveness. After the material liquid is atomized, its surface area is greatly increased, and it is rapidly mixed with the hot air flow. During this process, 95%-98% of the water evaporates rapidly in 5-15 seconds, resulting in instant drying. This fast drying speed not only improves production efficiency, but also provides a strong guarantee for product quality.
In addition, the special air splitter design further improves the performance of spray drying. It not only reduces the resistance of the equipment during operation, but also optimizes the processing air volume of the dryer, thus ensuring a stable and efficient drying process.
For producers, this continuously controlled drying method greatly simplifies the production process. Liquid raw materials with a moisture content of 40-90% can be spray-dried to obtain powdered products without additional processes such as crushing or screening. This not only reduces production costs, but also improves the purity of the product.
What's more, this drying method is suitable for the handling of heat-sensitive materials. Since the material is dried in a short time, its original color, aroma and taste can be preserved to the greatest extent. The dispersion, fluidity and solubility of the product can also be adjusted as needed, and the particle size, looseness and moisture content can be flexibly adjusted within a certain range.
In summary, centrifugal spray drying has become an indispensable and important process in the liquid process forming and drying industry due to its high efficiency, flexibility and adaptability. Whether for large-scale production or lab-scale experiments, it is ideal for generating high-quality powder, granular, or bulk solids.
