Design parameters of bread crumbs:

  According to the characteristics of bread crumbs, vibratory fluidized bed dryer is selected. Vibratory fluidized beds are vibrated on a conventional fluidized bed. The fluidization of the ordinary fluidized bed is realized entirely by the energy of the air. In the vibrated fluidized bed, the fluidization and transportation of the material is mainly realized by vibration. The hot air is mainly used for heat transfer and mass transfer, and takes the heat away, which obviously reduces the amount of hot air and saves the energy. In addition, the material breakage decreases and the dust entrainment is less.
      This drying system mainly includes blower, air heater, vibrating fluidized bed, cyclone collector, bag dust collector, induced draft fan, exhaust pipe and other equipment.
 
Equipment features:
(1) the heat transfer effect is good, because the material has a large contact area in the drying medium, and the material is constantly fluidizing in the bed. The heat transfer effect is good, the coefficient of heat capacity is large and can reach 8400~25000KJ/m3h C.
(2) the temperature distribution is uniform, because the temperature distribution in the fluidized bed is uniform, it avoids any local overheating of the product, and is especially suitable for the drying of some heat sensitive materials.
(3) flexible operation, continuous drying and cooling operation can be carried out in the same equipment.
(4) the bed plate is perforated by laser, the shape is a strip hole, and the hole width is only ten silk, so as to reduce leakage.
(5) the residence time can be adjusted, the residence time of the material in the dryer can be adjusted according to the need, so it is more suitable for the fluctuation of the water content of the product.
(6) less investment, and the drying device itself does not include mechanical moving parts. The device has low investment cost and small maintenance workload.
(7) fluidization and transportation of materials are mainly achieved by vibration, thus significantly reducing air consumption and energy consumption.
(8) fluidization is well proportioned without air gap and blow through phenomenon. Uniform drying and cooling products can be obtained.
(9) good adjustability and wide adaptability. Material layer thickness and movement speed in machine and full amplitude change can be adjusted.
(10) It has little damage to the surface of the material and can be used for drying fragile materials; irregular particles of the material do not affect the working effect.
(11) a fully enclosed structure is adopted to effectively prevent cross infection between materials and air and clean the working environment.
(12) the mechanical efficiency and thermal efficiency are high, and the energy saving effect is good. It can save energy 30-60% compared with the general drying device.
(13) all the angle of the contact between the main body and the material is a smooth transition, the welding is full welding, and the inner and outer surfaces are all polished, without dead angle and convenient for cleaning.
