ZDL Vibrating Fluidized Bed

Overview

  A vibrating fluidized bed dryer is a new type of high-efficiency continuous drying equipment that combines vibration technology with the principle of fluidized bed drying. It introduces vibration energy on the basis of a traditional fluidized bed dryer. An exciting force is provided by vibration motors, causing the material to jump and flow in a directed manner on the bed surface. The equipment mainly consists of vibration motors, a fluidized bed body, a gas distribution plate, an air inlet system, an exhaust system, and a control system. It adopts a fully enclosed structure, which can effectively prevent cross-contamination between the material and the air. The equipment is not only suitable for drying operations, but can also simultaneously or independently perform various process operations such as cooling and humidifying of materials. It is widely used in industries such as chemicals, pharmaceuticals, food, grain, and mining.

Working Principle

  The working principle of the ZDL vibrating fluidized bed is a fluidized drying process under the combined action of vibration and hot air. The material is continuously fed into the machine through the feed inlet. Under the exciting force generated by the vibration motor, the material is thrown in the horizontal direction and moves forward continuously in a jumping manner. At the same time, hot air enters the lower air chamber from the air inlet at the bottom of the equipment, is evenly distributed through the gas distribution plate, and then passes upward through the fluidized bed layer, performing sufficient heat exchange with the material particles in a fluidized state. Under the combined action of the vibration force and hot air flow, the material forms a good fluidized state. After the moisture is heated and evaporated, it is discharged from the exhaust outlet together with the hot and humid air after dust removal by the cyclone separator. The dried material is continuously discharged from the discharge outlet, achieving continuous operation throughout the entire process.

Features

  The ZDL vibrating fluidized bed offers several outstanding performance features. First, it provides uniform and stable fluidization, with no dead bed or blow-through phenomena, ensuring uniform drying and cooling effects. Second, it delivers significant energy savings, with high mechanical and thermal efficiency, achieving energy savings of 30% to 60% compared with general drying equipment. Third, it offers excellent adjustability and wide applicability. The material layer thickness, the moving speed of the material inside the machine, and the amplitude can all be steplessly adjusted, allowing flexible adjustment according to the process requirements of different materials. Fourth, it causes minimal damage to the material surface, making it especially suitable for drying fragile materials and crystalline materials. Fifth, it operates smoothly with low noise. Driven by vibration motors, it is easy to maintain and has a long service life. In addition, the equipment adopts a fully enclosed structure and can operate under slight negative pressure, providing a clean working environment. It can also perform multiple operations such as drying, cooling, and humidifying simultaneously according to user requirements.

Applications

  The ZDL vibrating fluidized bed has an extremely wide range of applications, covering many industries such as chemicals, pharmaceuticals, food, grain, minerals, and light industry. In the chemical industry, it can be used for drying materials such as boric acid, borax, ammonium sulfate, compound fertilizer, white carbon black, hydroquinone, catalysts, polyvinyl chloride, light calcium carbonate, and anhydrous sodium sulfate. In the pharmaceutical industry, it is suitable for drying glucose, gulonic acid, granulated pills, capsules, and traditional Chinese medicinal materials such as Anemarrhena asphodeloides, Platycodon grandiflorus, and Atractylodes macrocephala. In the food industry, it is widely used for drying and cooling citric acid, monosodium glutamate, granulated sugar, refined salt, soybean meal, distiller's grains, trehalose, fermented broad beans, seeds, etc. In the grain and mineral industries, it can be used for processing materials such as seeds and slag. The equipment is particularly suitable for processing powdery and granular materials, and also has good drying effects on materials with poor flowability, some stickiness, and heat sensitivity. It is an ideal integrated equipment for drying, cooling, and humidifying in continuous production.
