Boiling dryer _ _ A detailed map of the processing fluid bed dryer manufacturers

Device Overview boiling dryer boiling dryer is a drying device, also known as fluidized bed, generally by the heater, the fluidized bed [1] host, cyclone separator, bag filter, fan, operation table. Depending on the nature of the material, you may need an optional cyclone separator or bag filter. After the air is purified and heated, introduced from the bottom suction fan through the hole hopper screen. In the studio, negative pressure is formed by mixing and fluidization, after the water is evaporated and removed quickly, fast drying material. Boiling dryer is also very broad scope, such as pharmaceutical, food and other industries in the granulated, powdered or granular materials drying wet coating and medicines, etc. Thus, the boiling dryer in the pharmaceutical sector has played a huge role. But in the course materials should be noted that within the space of the machine than the drying effect of the factors of efficient drying time, drying materials affect the size and shape so as not to damage the quality of products. In recent years, boiling dryer has significantly improved its process technology, it can adapt to market demands. I believe that as technology advances, drying equipment boiling range of applications will be further expanded. Boiling drier air distribution plate has two roles, one support material layer, the second is the gas distribution. Distribution plate hole size, shape, distribution situation, the opening rate and so plays a crucial influence on the distribution of the fluid. Gas distribution is uneven, make the bed a "circulation", it tends to bed extremely easy to make some parts of a "channeling", while the remaining parts are dead bed, when most of the gas along the bed Some passages in the form of "channeling" short circuit through the bed to leave, so gas-solid contacting deteriorated significantly, which should be developed to avoid. Good distribution plate design, should be able to suppress unevenness appear bed, that is, when some parts of the bed pressure drop due to reduced airflow velocity increases, the resistance generated by the distribution board should be able to suppress an increase in the gas stream, thereby inhibiting fluidized worse.
