The spray drying nozzle design, manufacture and operation problems should be noted that 1) gas flow nozzle for industrial production, the liquid outlet pipe diameter (inside diameter) should be as large a number, this will increase the gas - liquid contact periphery, so that thin film more conducive to atomization. In the gas - liquid ratio under the same conditions, liquid nozzle inner diameter larger (so as not to produce liquid pulse phenomenon limit), the more fine droplets. If the droplet size remains constant, the liquid nozzle inner diameter larger, more provincial air. In addition, the large nozzles another prominent advantage is not easy to be a slug or clogging impurities. Small nozzle (nozzle diameter 3 ~ 5mm) due to frequent congestion, to the operator a lot of trouble, and affect product quality and yield. Currently used nozzle diameter (inner diameter) of up to more than 20 mm, then only the coarse filter, there is almost no clogging, stable operation. Therefore, the design of industrial nozzles, with large diameter nozzle is appropriate. 2) nozzle structural problems. Some walls of the nozzle outlet is too thick, 4 ~ 5mm, affect the gas - liquid contact, thereby affecting the atomization. Meanwhile, in the thick of the end surface of the outlet pipe, adhesion wet material to produce a wet gob off, affect product quality. Suitable wall thickness of 0.5 ~ 0.6mm. Drying machinery and equipment is one of the important raw material medicine equipment, used in the pharmaceutical field is very extensive. Currently, in many drying equipment, Spray Dryer is one of the higher value of the dryer, from between several hundred thousand to several million units each. In Wenzhou, Shanghai, Wuxi, Jiangyin, Xining and other places have a number of professional factory spray, spray drying equipment to provide hundred of users every year. From the research, academic papers each country will be the drying, spray drying technology research accounted for first in the models, the extensive application of the theory of imperfect and always attracts the attention of a large number of researchers. Selection spray should pay attention to what time detailed elements of the food industry: fat-rich milk, armpit protein, cocoa milk powder, substitute milk powder, animal blood meal, egg white (yellow) whole egg powder, etc., fast-drying, the material liquid is atomized After the greatly increased surface area, in the hot gas stream can be evaporated instantly 95% to 98% moisture, the drying time of just a few seconds to complete, especially suitable for drying heat-sensitive materials. Spray with good uniformity, fluidity and solubility, high purity, good quality, it is a way to complete the drying and granulating device simultaneously. Can be adjusted according to process requirements of feed pump pressure, flow rate, the size of the orifices of the desired size by a certain percentage of spherical granules. Changzhou City, Su Cheng Drying Equipment Co., spray in the hot air flow, the moment can be evaporated 95-98% moisture, drying time is only required to complete ten seconds to tens of seconds species, especially for heat sensitive materials drying technique used for drying materials in particular, but also the use of high-speed centrifugal atomization allows material dispersed into a mist, and the hot air full access, complete instant dry, powdery form drying means finished.
