Application of Vibrating Fluid Bed Dryer in Sugar Drying
Vibrating fluidized bed drying technology is a well-established and widely applied method in various industries such as chemicals, feed, food, and light industry. In the early 1990s, Shenyang Yitong Venture Technology Co., Ltd. collaborated with Northeastern University to introduce this technology into the drying process of white granulated sugar. This innovation significantly improved the quality and efficiency of sugar drying, particularly for refined castor sugar. The implementation not only enhanced product quality but also ensured high drying efficiency, safety, and reliability.
For many years, Shenyang Yitong Venture Technology Co., Ltd. has continuously focused on research and development in vibrating fluidized bed drying technology, leveraging the technological expertise of Northeastern University. Over time, the company has accumulated extensive theoretical knowledge and practical experience. Today, their vibrating fluidized bed dryers are extensively used in numerous sugar factories across Guangdong, Guangxi, Yunnan, Inner Mongolia, and Xinjiang, maintaining their leadership in large-scale vibrating fluidized bed drying technology.
The design of large-scale vibrating fluidized beds for sugar drying and the selection of appropriate drying equipment are critical. First, based on the initial and final moisture content of granulated sugar, drying temperature, and cooling requirements, the drying medium and required cooling medium flow rate are determined. Then, considering the fluidization velocity of the sugar particles, the necessary area for drying and cooling is calculated, which helps determine the specifications of the selected vibrating fluidized bed dryer (cooler).
In industrial production, the size of sugar particles typically ranges from 0.3 mm to 1.5 mm, with a moisture content between 0.5% and 1.0%. The fluidization velocity of sugar in the fluidized bed during drying is approximately 0.6 m/s to 1.0 m/s. When selecting equipment, it is essential to ensure a reasonable proportion between the length and width of the dryer to guarantee sufficient drying time and proper bed thickness during both drying and cooling processes. A reasonable bed thickness ensures an effective fluidized state, thereby enhancing drying efficiency.
The typical bed thickness for sugar drying and cooling ranges between 100 mm and 200 mm, with an aspect ratio between 6 and 8, which is considered optimal. At the Guangdong Shunde Sugar Factory, the technical specifications of the sugar drying-cooling unit include:
- Processing capacity: 50 tons per hour (two production lines)
- Sugar particle size range: 0.3–1.5 mm
- Sugar type: Premium grade, first and second class white granulated sugar, refined sand sugar
- Wet sugar moisture: 1%
- Wet sugar temperature: 50°C – 60°C
- Drying hot air temperature: 100°C – 150°C
- Cooling air temperature: Ambient temperature
- Moisture after drying: ≤ 0.04%
- Temperature after cooling: ≤ 10°C above ambient
- Dust recovery rate: 99% using first-class cyclone dust collection
