Anhydrous citric acid vibrating fluidized bed dryer: The drying system has an air flow rate of L=23600m3/h, which is evenly distributed by two blowers. One of them is a preheating drying blower, which processes materials with high moisture content, high specific gravity, and poor dispersibility. Its model is 9-26 4.5A 11Kw, speed: 2900r/min, air flow rate: 4400-4500m3/h, air pressure: 4400-4300Pa;
