Stem existing drying equipment flaws and shortcomings. Research and development of low-energy-efficient air dryer wire stems. The device uses a venturi tube and dryer set separately in order to improve the thermal conversion efficiency drying system by suspension technology to improve the hot and dry stems of heat and mass transfer coefficient silk and traditional silk terrier tunnel dryer were applied compare . The results showed that: ① the entire wire rate increased 5 percentage points lower percentage of broken wire slaughter: 39.6%; ② dry stem silk exports from poor moisture content is reduced to 0.61% 2%, sensory quality cigarette samples average increase of 0.5 points; ③ processing unit mass Stem reduced by an average 34.63% energy consumption. Is there any additional requirements on the dried product: high velocity air stream dryer so that between the particles, violent collision and friction between the particles and the wall, the material is easy to crush and wear, and more difficult to be kept intact crystalline form and the crystalline gloss lower, so the air dryer for drying the product has the above requirements, the suitable drying methods. High efficiency air dryer hot air drying and the use of gas-solid flow operations offer air dryer, air dryer and Changzhou in the surface gasification stage, the material is always in the wet-bulb temperature of the gas and its access solution drying air dryer, general not more than 60 ~ 65 ℃, the temperature rise in the drying stage of the end of the material, the gas temperature has a large decrease, the product temperature does not exceed 70 ~ 90 ℃. Air dryer offer, Kinder dry (certified), air dryer provided by Changzhou Drying Equipment Co., Kinder. Kinder Changzhou Drying Equipment Co. (www.jian-da.com) is an industry leader in Changzhou, Jiangsu, drying equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Kinder dry leadership with the staff warmly welcome all inquiries negotiations to create Kinder dry a better future.
