XLP series Spray Dryer closed circulation system circulating inert gas as the gas, the dried material has a protective effect of a spray application, the recycle gas through the wet carrier, dehumidification process, the media can be reused; nitrogen gas heated by the heater into the Use a spray drying tower, liquid materials are delivered to the centrifugal screw pump nozzle at high speed circulating liquid is atomized into droplets atomizer, heat and mass transfer process is completed in the drying tower was dried powder material from the tower bottom discharge, the organic solvent was evaporated under a gas pressure of the negative pressure fan, the dust entrained in the gas through a cyclone, dust spray tower saturated organic solvent gas is condensed into liquid by the condenser discharge condenser, not The drying carriers used in the re-circulation system, after the continuous heating condensable gaseous medium. The conventional ordinary centrifugal spray drying is through continuous delivery, exhaust humidity achieve the purpose, which is a significant difference between the Ex-closed centrifugal spray drying equipment and ordinary centrifugal spray drying equipment; drying system for drying medium N2 spray dryer, the internal positive pressure operation, to maintain a certain positive value, if the internal pressure drops, the pressure transmitter to automatically control the amount of N2 inlet, ensure that the system pressure balance. Chinese medicine extract special dryer is designed to solve medicine Spray and plant extracts, it solves the following materials appear in the original LPG high-speed drying spray dryer in medicine extract: 1, material sticky wall, low income powder; 2, the material in the walls of coking stay a long time, resulting in deterioration of the material phenomenon 3, difficult to clean, does not meet the 高标准 requirements; 4, low yield: LPG-150 type spray dryer, the yield can only handle 50 -60kg / h feed solution. In view of the above situation, I plant in accordance with traditional Chinese medicine extract the material properties and process requirements and design problems Dryers medicine, good material color after drying, not bad, greatly improve the economic efficiency of the factory, and LPG medicine extract high-speed centrifugal Compared spray dryer has the following characteristics: 1, using three air purification, the inlet air to reach 300 000 requirements; 2, using a cold wall means, the inner wall temperature of 80 ℃, the material in the walls of the residence nor coking ; 3, the entire volume of the original LPG centrifugal spray of 3.5 times the standard. 4, using quick washing device, suitable for multi-variety production in claim 5, dust with a wet dust spray dryer prices, so no dust out, comply with environmental requirements; 6, using air-cleaning device, the effect is more satisfying; 7 It offers two sets of atomizer and frequency control 8, using a PLC control, program control system screen display; 9, can be equipped with a flushing device 10 can be equipped with a dry air density closed conveyor; spray dryer model, step dry low price (certified), spray dryer by step Drying Equipment Co. Changzhou. Drying Equipment Co., Ltd. Changzhou step (www.yibu.com) is an industry leader in Changzhou, Jiangsu, drying equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
