Vibrating fluidized bed drying technology is a relatively mature drying technology, widely used in chemical, feed, food, light industry and other fields. In the early 1990s, Shenyang Yitong Venture Technology Co., Ltd. cooperated with Northeastern University to apply vibrating fluidized bed drying technology to the drying area of ​​white granulated sugar, which changed the backwardness of the original domestic sugar drying, especially the drying of refined castor sugar, which not only improved the sugar content. The product quality, and high drying efficiency, product safety and reliability. For many years, Shenyang Yitong Entrepreneurship Technology Co., Ltd. has relied on the technological advantages of Northeastern University and has been dedicating to the research of vibrating fluidized bed drying technology. It has obtained a wealth of theoretical research results and gained a lot of valuable experience in practice. At present, the company's vibration flow The chemical bed dryer has been widely used in dozens of sugar factories in Guangdong, Guangxi, Yunnan, Inner Mongolia, and Xinjiang, and it has always maintained the company's leading position in large-scale vibration fluidized bed drying technology.  The design of large-scale vibrating fluidized bed in the drying of sugar and the selection of drying equipment are very important. Firstly, according to the requirements of initial and final water content of granulated sugar, drying temperature and cooling requirements, the drying medium and the required cooling medium flow rate are determined. According to the fluidization speed of granulated sugar, the required area for drying and cooling is determined, and then the selected vibration flow is determined. Bed dryer (cooler) specifications. Under the conditions of industrial production, the size of sugar generally ranges from 0.3 to 1.5mm and the humidity is between 0.5% and 1.0 %. The fluidization velocity of sugar in the fluidized bed drying is approximately 0.6m/s to 1.0m/. s . When selecting the equipment, it is necessary to reasonably determine the proportional relationship between the length and the width so that the drying time of the sugar can be ensured, the thickness of the bed during the drying and cooling of the sugar can be ensured, and the reasonable bed thickness can be ensured. The fluidized state can improve the drying efficiency. The bed thickness of the general sugar drying and cooling is between 100 mm and 200 mm , and the aspect ratio is between 6 and 8 , which is reasonable. The technical indicators of the sugar drying - cooling unit of Guangdong Shunde Sugar Factory are: ̈         Processing capacity: 50 tons / hour, (two production lines). ̈         Sugar size range: 0.3 to 1.5mm ̈         Sugar type: excellent grade, first and second white granulated sugar, refined young sand. ̈         Wet sugar moisture: 1% ̈         Wet sugar temperature: 50 °C ~ 60 °C ̈         Drying hot air temperature: 100 °C ~ 150 °C ̈         Cooling air temperature: room temperature ̈         Sugar water after drying: ≤ 0.04% ̈         Sugar temperature after cooling: ≤ 10 °C ambient temperature ̈         Sugar powder recovery rate: First class cyclone dust recovery, dust removal efficiency of 99% .
