Tapered Chamber : The conical shape of the expansion chamber reduces the velocity of the air in the filter chamber by 50%. The reduction in velocity helps to keep the smaller or fine particles out of the upper filter region and below the spray nozzles when granulating. A secondary benefit is a reduction in the total height of the expansion chamber.
Process Filtration:
One Piece Bag : The one piece filter bag system extends from the bottom of the expansion chamber to the top. The filter can be shaken to remove any material. The filter prevents product from accumulating on the stainless steel chamber walls and the stainless steel chamber walls are not exposed to the product, thus eliminating product accumulation and lowering operating temperatures.
Cartridges : Cartridge filters are installed in the upper portion of the expansion chamber. The cartridges are automatically pulsed clean permitting continuous fluidization of the material.
Bag/Cartridges Combination: The one piece bag/cartridge filter system combines the benefits of both filter systems.
Conidur or Turboflo Bed Plate : The bed plate provides uniform distribution of the air eliminating channeling and non-uniform fluidization patterns. The plate is constructed of a heavy gauge stainless steel allowing a variety of utensils to be used in product removal and cleanup.
Agitator System : The agitator system located in the bottom of the bowl rotates slowly through the bed of material ensuring proper fluidization of the product.
Spray/Liquid Delivery System : In granulation systems with more than one spray nozzle, the nozzles are mounted in a "chandelier" pattern that spreads the nozzles out and points them straight down at the bed. This approach provides more uniform coverage of the fluidized bed and has higher operating efficiencies. Each nozzle has its own pump to ensure consistent and identical flow to all of the spray nozzles.
Scale Up : Fluid Air fluid bed systems are designed to maintain critical scale up factors like average air velocities and air changes (quantity of air per cubic foot of product) as constant as possible from one unit to the next. From our Model 0050 bowl size on up, units operate at nearly identical bed depths, air velocities and air changes. This simplifies scale up of products from one unit to the next.
