Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying medium.
LSP-5000 spray dryer is a drying equipment suitable for the liquid material with low temperature and high viscosity, which has been improved many times on the basis of domestic and foreign spray dryers. The working principle is: cold air is filtered through the filter, then enters the heater, is heated to a certain temperature, and then enters the air distributor at the top of the spray tower, and the hot air spirally flows to the bottom of the tower. The liquid is pumped to the centrifugal atomizer at the top of the tower body, and the liquid is torn into extremely small mist droplets. The liquid droplets and the hot air are in parallel contact, and the heat exchange is fully performed. The water content is rapidly vaporized and evaporated, and dried in a very short time as a finished product. The finished product is separated by a cyclone and discharged, and the exhaust steam is discharged by an induced draft fan.
1. The equipment drying time is short, only need 5 seconds, the general effective ingredients will not be destroyed.
2. Spray tower diameter can adapt to a variety of materials to dry, inlet and outlet air temperature is adjustable air temperature, wide range of work.
3. Equipment configuration is complete, to meet the production process requirements from the maximum extent.
4. Simple operation, wide range of adaptation, no professional operators.
5. Unique inlet screw distributor, is the company's patent, to ensure that the tower in the circumference, the air flow is absolutely uniform down, to minimize the material sticky wall.
6. Advanced and convenient cleaning door, can facilitate the operation of workers, but also to ensure absolute sealing, so that the material is not sticky wall, the tower is equipped with a clean door, to facilitate all-round cleaning.
7. tower absolute mirror polishing, without any dead ends, one is to avoid sticky material, the second is to facilitate cleaning.
8. The inlet temperature is controllable and can fully satisfy the drying process of the material.
9. All pipes, cyclones are equipped with quick opening mouth.
10. Heater is improved into a U-tube form, to overcome the heating tube thermal expansion and contraction caused by weld cracks. U-shaped tube outside the shell, to avoid the air leakage between the pipe and the tube. Fins with aluminum alloy, improve the heat transfer coefficient and heat transfer efficiency.
