XO-LPG Series High Speed Centrifugal Atomizing Dryer  Descriptions

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, soliquoid 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.

Principle of Work

After filtering and heating, the air enters into the air distributor at the top of the dryer. The hot air enters into the 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

 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 a moment. The time of completing the drying needs only several seconds.

2. It is especially suitable for drying the heat sensitive materials. Its 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  powder or particle products once a time. After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and enchance the product purity. The product particle diamenters, looseness and water contents can be adjusted through changing the operation condition in a certain scope. It is very convenient to carry out the contorl and management.

Outlines

1. Atomization:Atomizing system must insure the fogdrops distributing uniformly.

2. Contact of hot air flow and fog drops: When enough hot air enter into drying tower, the flow way and angle have to be considered, no matter co-current flow, adverse current or mixed flow, must insure the sufficient heat exchange, it is crucial.

3. The angle design of pipelines and cone: It is very important to select the suitable angle, here we would like to share our experience from production of thousands of this equipments.
