Technical Field
[0001] This utility model relates to the technical field of vibrating fluidized bed dryers, specifically to a vibrating fluidized bed dryer for ammonium sulfate production. Background Technology
[0002] A vibrating fluidized bed dryer is a specialized drying device, typically used for the final drying of materials. It is widely applicable in industries such as chemical, pharmaceutical, and food processing. The entire dryer is supported on a base by springs. Vibrating motors are mounted on one or both sides of the dryer. Under the action of vibration, the material is thrown forward continuously in a horizontal direction. Simultaneously, hot air is introduced from under the bed, fluidizing the material and ensuring full contact between the material and the hot air, resulting in uniform drying. In ammonium sulfate production, a vibrating fluidized bed dryer is required. During the drying process, the fluidized bed needs to be continuously fed. Since undried ammonium sulfate is moist and easily adheres to surfaces, continuously adding ammonium sulfate to the dryer can cause it to accumulate at the top of the fluidized bed, leading to uneven heating, moisture content deviation, and ultimately reducing the drying effect and production quality.
