It is based on atomizing nozzle and flow-drying devices. Through the material balance and energy and dryer set operating parameters of the structural parameters,This design uses a pressure nozzle. Through the nozzle into the structure and terms Liaoliang dryer in diameter In addition, through the ventilation tower in terms of tracks, the two determined integrated tower Drive. The height of the dry determined by strength of estimates, and height and diameter than the application of accounting and dust removal device using a cyclone and bag filters. In real value, in the operation to maintain a certain flexibility and the appropriate pressure drop, under the premise of a more rational design of the structure and drying tower subsidiary of the device structure, spray drying system to improve the efficiency and yield to achieve the purpose of more energy saving. Spray drying is to spray the liquid material into the heat of the dry powder into a medium transit materials. It is dry, including a particle materials for processing. Feeding can be a solution, suspension and paste. Liu was made of dry powder, granules or poly form clumps. Spray drying operation in many industries to meet the expected quality indicators stem the requirements for products for further processing or for direct consumer use. After decades of in-depth research and development, spray drying has become to many varieties of dry products, the competitiven
