Descriptions
The centrifugal spray dryer is the widely used technology in the liquid shaping technology and drying industry.Lt is most suitable for producing powder, particle solid products from materials of solution, emulsion, solidus and culpable paste states, Therefore, when the particle size of the distribution final products, the residual water contents, the stocking density and the particle shape meet the precision standards, the centrifugal spray dryer is one of the most desired technologies.

Principle of work
After filtering and heating, the air enters air distributor at the top of the dryer. The hot air enters the e drying chamber in the spiral form uniformly. By passing through the high-speed centrifugal atomizer at the top of the tower, the material liquid will be rotated and sprayed into extremely fine mist liquid beads, Through the very short time of contacting with hot air, the materials can be dried into the finished products. The finished products will be discharged continuously from the bottom of the drying tower and from the cyclone separator.The waste gas will be discharged by blower.

Features and Outlines
Features
1 .High speed of drying. After the spraying of the 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 the moment.The time of completing the drying needs only several seconds.lt is especially suitable for drying the heat sensitive materials.
2. Ats final products own the good uniformity, mobility, and dissolving capacity. And the final products are high in purity and good in quality,
3. The production procedure is simple and the operational control easy. The liquid with the moisture contents 40-60% (for special materials, The contents may reach 90%.)can be dried into powder or particle products at a time. After the drying, there is no need tor smashing and sorting, so as to reduce the operation procedures in the production and Chance the product purity .The product particle diam enters, looseness and water contents can be adjusted through changing the operation condition in a certain scope, It is very convenient to carry out the control and management.
Outlines
1. Atomization: Atomizing system must ensure a uniform distribution of the fog drops, which is crucial to ensure a good qualified rate of products.
2. Contact of hot airflow and fog drops: When enough hot air enters into drying tower, the direction and angle of hot air flaw have to be considered, no matter co-current flow, adverse current or mixed flow, must ensure the sufficient heat exchange, it is crucial.
3. The angle design of pipelines and cone: Lt is very important to select the suitable angle, here we would like to share our experience and data from production of thousands of this equipment.
