Spray drying nozzle design, manufacture and operation should pay attention to the problem of nozzle fixed on methods to ensure that the impact can not be due to frequent disassembly and concentricity. If the concentricity of the gas and liquid nozzle deviation is larger droplets will be a big, serious cause localized sticky wall phenomenon. Therefore, in manufacturing, we must ensure concentricity requirements. 3) the care and maintenance of the nozzle. When mounting and dismounting the nozzle, you must be careful to operate. Machined metal parts, has a high precision, performance when holding the nozzle must prevent any slight damage. After the nozzle operation is stopped, to remove the nozzle cleaning for reuse. 4) atomizing air pressure to be kept constant. Excessive fluctuations will obviously cause fogging uneven, especially when a sudden drop in pressure, will have serious sticky wall phenomenon. Therefore, the supply of compressed air the best plane. 5) the use of water vapor as the atomizing gas, shall, before it enters the nozzle in the vapor condensate removed. Preferably superheated steam. Instead of compressed air atomized material was treated with steam (particularly superheated steam) is more economical. With the fast development of new product development of China's economy, and food, chemical and biological, chemical, biotechnology and other industries, research new technologies, with the quality of material life are increasingly high, especially after China's accession to WTO , the international market for drying equipment industry demanding. However, our current drying technology advances, the overall technical level is still lagging behind, it is difficult to meet the demands of economic development due to related industries and product structure optimization and new product development. Large centrifugal Spray Dryer Overview: Spray drying is a liquid process shaping and drying the industry's most widely used process. Ideal for producing powder, granular solid product from the solution, emulsions, suspensions and burnt like liquid feedstock. Therefore, when the particle size distribution of the finished product, residual moisture content, bulk density and particle shape must meet the precision standard, the spray drying is an ideal process. Large centrifugal spray principle: the air is filtered and heated air into the dryer at the top of the dispenser, the hot air was evenly into the drying room in the spiral. Passing through the top of the tower high-speed centrifugal atomizer (rotational) was sprayed into the extremely fine mist liquid beads. Through contact with the hot air, in a very short period of time can be dried into a finished product. Finished continuously from the bottom of the drying tower and cyclone exhaust gases vented by the fan.
