Laboratory Equipment Xlp High Speed Centrifugal Sealed Circulation Spray Dryer/Dryer Machine for Liquid Raw Material
XLP Series Sealed Circulation Spray Dryer
Work principle:
Seal circulation spray drying system works in a seal circumstance. The drying gas is usually inert gas, such N2. It's applicable for drying material with organic solvent, toxic gas and the material easy to be oxidized. Adopt inert gas as circulation gas, so to protect the material to be dried. The inert gas circulates after dehumidification process. N2 is heated and then enters into drying tower. Liquid material is conveyed to centrifugal nozzle by screw pump, and then it's atomized into the liquid mist by the atomizer, the heat transferring process is finished in the drying tower. The dry product is discharged at the bottom of tower, the evaporated organic solvent is sucked by the vacuum generated by the fan. Power or solid material will be separated in the cyclone and sprinkling tower. The saturated organic gas is drained out after it's condensed in the condenser. The gas not condensed recycles in the system after it's heated continuously. Ordinary normal centrifugal spray drying process is realized by air conveying and exhausting process. This is the obvious difference between explosion proof type sealed circulation centrifugal spray dryer and ordinary centrifugal spray dryer. The drying media in drying system is N2, the interior is under positive pressure. To keep positive pressure stable, the pressure transmitter controls the inlet amount of N2 automatically.

The founder, Mr Zha Guocai devotes research, manufacture, production and business of drying equipment for over thirty years, holds the post of Deputy Director-General of China Drying Equipment Association for a long time.
The company pays much attention to science and technology renovation. First or later, it has cooperated with the institutes that are Shanghai, Wuhan, Chongqing and so on, and cooperated with Shenyang Chenmical Institute, Ministry of Chemical Industry, Qinghua University, Shanghai transportation University, Dalian Science and Technology University. Therefore the company can put 3-5 new varieties into the market every year. In 1998, through approval of state relevant departments, the company set up China Research Center of Drying and Granulating, that can research new process and develop new technology and provide new products for pharmaceutical, chemical and foodstuff industries. We have many testing machine in our lab for to make trials for clients.
We've sold equipment to USA, Mexico, Columbia, Guatemala, Brazil, Peru, Australia, New Zealand, Ghana, Russia, Cyprus, Greece, Iran, Indonesia, Philippines, Korea, Japan, Taiwan, Hongkong and so on totally nearly 50 countries and districts around the planet.
