The fan rotations are reversed every six feet to stop channeling of the product, which provides a more uniform, less stratified product size mixture. Horizontal fan discharge centered directly under the mesh belt maintains the fan plenum at a constant air pressure. Vertical air baffles prevent vortexing and stainless steel diffusion plates provide a positive, uniform air velocity across the entire belt surface. This is critical in maintaining dense suspension of your product. The inlet cones are mounted to the plenum deck, just above the coils.
Air is drawn by the fans through the cone and into the plenum.
The design of the cone allows the maximum amount of air to pass through them, thus reducing the amounts of pockets or gaps in the air pressure. This helps the air pressure to remain constant at the belt. Back to Cross Section Airflow Unique design of airflow returning to both sides of the coil improves the refrigerating effect at the coils by maintaining constant airflow across the coil surface. This design also assists in improving uniform velocity at the mesh belt. UHMW rollers strike the underside of the belt, preventing product from clumping.
