Centrifugal spray dryer is widely used in liquid forming and drying industries. Its working principle is mainly to atomize liquid materials into tiny droplets through high-speed centrifugal force, and mix them thoroughly with hot air to achieve rapid drying of the liquid.
Specifically, the working process of the centrifugal spray dryer is as follows: first, the air enters the air distributor on the top of the centrifugal spray dryer through the filter and heater, and the hot air enters the dryer evenly in a spiral shape. At the same time, the liquid is pumped from the liquid tank through a filter to the centrifugal atomizer at the top of the dryer. Under the action of centrifugal force, the material liquid is sprayed into extremely small mist like droplets, which come into contact with hot air and quickly evaporate moisture, thus drying into finished products in a very short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, while the exhaust gas is discharged by the fan. Users can also choose appropriate heating methods and dust collection and removal methods according to their actual needs.
The parameters of the centrifugal spray dryer mainly include flow range, effective pressure, lift range, motor power and external dimensions. The specific values of these parameters may vary depending on the model and specifications of the equipment.
The advantages of centrifugal spray dryer are mainly reflected in the following aspects:
Fast drying speed: After atomization, the surface area of the material liquid is greatly increased, and most of the water can be evaporated in an instant. The drying time is usually only 5-15 seconds, with the characteristic of instantaneous drying.
Good product quality: Due to the rapid drying process, the color, aroma, taste, and nutritional content of the product can be well maintained.
Easy to operate: The equipment has a high degree of automation, is easy to operate, and is easy to control.
Wide application range: suitable for all kinds of solutions, lotion, suspensions and pumpable pasty liquid raw materials to generate powdery and granular solid products.
Centrifugal spray dryer is widely used, especially for those products that need to strictly control particle size distribution, residual moisture content, bulk density and particle shape. For example, centrifugal spray dryers have important applications in chemical, food, medicine, ceramics and other industries.
In general, the centrifugal spray dryer has broad application prospects in many industrial fields due to its high efficiency, fast speed, easy operation and good maintenance of product quality.
