And positive vibration fluidized bed dryer and dried material from the inlet into the machine, the vibration force, the material along the horizontal fluid bed throw, continuous forward motion, hot air upward through a fluidized bed heat exchanger with wet material, moist air through the cyclone dust from the exhaust after 1: 3 discharge. Dried material is discharged from the discharge of imports for the chemical, pharmaceutical, food, dehydrated vegetables, grain, mineral and other industries powder, dry granular materials, cooling and other operations. Such as: citric acid, monosodium glutamate, borax, ammonium sulfate fertilizer, dill l, silk, soybean meal, distillers grains, seeds, slag, sugar and so on. Its performance advantages include the following aspects: 1, the vibration source is a vibrating motor drive, smooth operation, easy maintenance, low noise and long life. 2, fluidized symmetry, no dead gaps and broken phenomenon can obtain uniform drying and cooling products. 3, adjustable resistance, suitable wide. Material thickness and movement within the machine speed and full amplitude can stepless adjustment. 4, less damage to the material surface. Drying can be used for fragile materials, when irregular material particles does not affect work results. 5, fully enclosed structure. Effectively prevent cross infection between material and air, the working environment clean. 6, high mechanical efficiency and thermal efficiency, energy-saving effect, than the average drying device can save 30 to 60%.
