Between the material and the hot air heat and mass transfer in drying process, most of the water evaporated at this stage. Material by crushing and evaporation, the buoyancy is greater than gravity, material movement upward into the classifier. Material entrained gas in the spiral iron stearate dryer monopoly, under the action of centrifugal force, the small particle size of the material in the inner ring, larger and wet in the outer ring. When small particles of water to meet the requirements to be at the center of the gas from the drying chamber with the dryer, the large and continue grinding wet granules dried to ensure product moisture content and particle size uniformity. Changzhou and positive Drying Equipment Co. is a professional production of drying equipment, crushing, mixing equipment manufacturing enterprises. It provides engineering equipment selection, design, manufacture, installation and after-sale service series. Production of various drying equipment widely used in many fields of medicine, chemical, food, agricultural and sideline products processing, the company is strong in technology, processing equipment. Flash dryer drying principle; according to the role played by the drying process to build ultra-fine quartz powder dryer, the main device can spin flash dryer is divided into three parts: the bottom of the fluidized section, asked in the drying section, the upper part level segment. Different segments structure, the role is not the same. (1) flow of materials segment of the population is the following sections, equipped with a stirrer. It helps break the highly viscous material, and the wet material and dried hot air full access, resulting in maximum heat transfer coefficient. Changzhou City Drying Equipment Co., and the positive advantages: flash dryer, rotary drum dryer, fluid bed dryer, air dryer, belt dryer, vibration fluidized bed dryer inosine sodium dryer manufacturers, spray drying machines, vacuum dryer, paddle dryer, tray dryer, mixer, granulator machine. Made superfine quartz powder dryer, and a positive drying integrity management (certification), dryer and positive by Changzhou Drying Equipment Co. Changzhou City Drying Equipment Co., and positive (www.hzdrying.com) is a 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. And being dried in leadership with the staff warmly welcome all inquiries negotiations to create a positive drying and a better future.
