ZLG series vibrating fluidized bed

The ZLG series vibrating fluidized bed introduces materials into the machine from the feed inlet, and under the excitation force provided by the vibration motor or other means, jumps forward on the air distribution plate. At the same time, the air is filtered and heated to a certain temperature, and enters the lower air chamber of the dryer through the air outlet. Under the dual action of vibration force and the hot air flow evenly distributed through the air distribution plate, the materials are suspended and in contact with the hot air flow,

　　ZLG series vibrating fluidized bedThe material enters the machine from the feeding port and jumps forward on the air distribution plate under the excitation force provided by the vibration motor or other means. At the same time, the air is filtered and heated to a certain temperature. It enters the lower air chamber of the dryer through the air outlet. Under the dual action of vibration force and the hot air flow evenly distributed by the air distribution plate, the material is in a suspended state and comes into contact with the hot air flow. Intense turbulence occurs between the material particles and the heat medium, which enhances the heat and mass transfer process. The dried product is discharged from the discharge port, and the evaporated moisture and waste gas are recovered by the cyclone separator and discharged into the atmosphere after dust is collected. The lower bed body provides a stable air chamber with a certain pressure for the bed layer. Adjust the induced draft fan to maintain a slight negative pressure on the upper part of the bed material in the upper box, maintain a good dry environment, and prevent dust leakage.

Scope of application:

Pharmaceutical and chemical industries: various tablet granules, boric acid, borax, ammonium sulfate, hydroquinone, malic acid, maleic acid, etc. Food and building materials: wine troughs, monosodium glutamate, sugar, salt, slag, Douban, seeds, etc.

It can also be used for material cooling, humidification, etc.

Features:

The material is heated evenly, with sufficient heat exchange and high drying intensity, saving about 30% energy compared to ordinary dryers. The vibration source is driven by a vibration motor, which has balanced operation, easy maintenance, low noise, and long service life. Fluidization stability and blow through phenomenon. Small damage to the surface of the material, suitable for fragile drying, and does not affect the working effect even when the material particles are irregular.

Adopting a fully enclosed structure effectively prevents cross contamination between materials and air, resulting in a clean working environment. Good adjustability, adaptable to a wide surface, capable of achieving stepless adjustment of material layer thickness, internal movement speed, and amplitude changes.

Due to the application of vibration, the minimum fluidization gas velocity can be reduced, which can significantly reduce the air demand and thus reduce the entrainment of dust layers. The matching heat source, fan, cyclone separator, etc. can also be correspondingly reduced in size, and the complete equipment can be reduced, resulting in significant energy-saving effects. It is convenient to change the residence time inside the machine by adjusting the vibration parameters. The piston flow operation reduces the requirements for material particle size uniformity and regularity, making it easier to obtain uniform dried products.
