Impinging stream drying in industrial applications

Impinging stream drying in industrial applications (two)
   1 drying of pharmaceuticals
   For drying powder and granular medicines. Dried material from the dryer into the auger bottom mixing chamber in which hot air and 180 ℃ mixture, after the introduction of a nozzle perpendicular to the bottom of the inner tube by tube, and by the number at the top of the inner tube vanes ejected in the vertical tube formed on the inner cyclone hit. Simultaneously. On top of the tube in a vertical collision tangentially into one of a temperature of 150 ℃ auxiliary air flow is formed in the tube outer cyclone. Outer swirl within the tube the same direction of rotation of the inner cyclone. Bottom-up pieces of material inside the swirl of the material to the wall due to the centrifugal force migration. The material of the outer cyclone the process of drying the collision, and gradually to the bottom of the vertical sliding of the control, the final product is discharged from the bottom. Carried out by air from the top of the fines collected by the separator. Product of the total harvest rate of 98% on a 99%. This drying equipment, stable, equipment handling capacity up to 10000kg / h.
   2 dried skim Rougu slag
   The use of meat and bone meat processing enterprises slag, the production of animal feed protein, has an important economic value and social benefits.
   3 feed grain temperatures impinging stream processing
    In addition to requiring dry fodder plants drying time is as short as possible in order to prevent the destruction of the protein, they also need to meet another important process requirement that a reasonable conversion of starch. In feed grains (and forage), usually containing up to 75% of the starch. By livestock in order to facilitate digestion and absorption, to turn these starch into simple carbohydrates - dextrin and sugar.
   4 dried wood scrap
    Wood debris (including wood fibers and wood shavings, etc.) drying, is a man with wooden planks and other scrap wood as a raw material in the production of an important part.
    For the production of MDF wood fiber moisture content requirement is 10% left stone, and thus, as long as the initial temperature of the drying gas> 80 ℃, can be combined to achieve once impinging stream drying dehydration requirements. Use of higher air temperatures can be further improved dewatering and drying yield, the wood fiber, suitable drying air temperature of 80-ll0 ℃.
After drying for wood scrap microstructure analysis and mechanical properties of the test and found that combination by impinging stream drying, the material did not produce crushing, fracture and other mechanical damage and internal structure of the macro-micro damage, product quality in line with plywood industry for wood raw material requirements.
