The
OP><FLO (Opposite Flow) or Counterflow process is the refined
technology of exposing processed product to an upward moving stream
of ambient airflow. As the air rises through the product, it is warmed,
increasing the moisture carrying capability of the air. The product
just entering at the top of the cooling chamber is exposed to the warmest
air available within the cooler minimizing temperature shock. The product
exiting the bottom of the unit is cooled to within 5-10° of the
ambient air temperature. The product and air have opposite flows.
The gradual heat transfer greatly enhances the product quality and reduces
stressing and fines.
Bliss Coolers are
available in either a rectangle, square or circular cooling chamber
design, the latter being the newest technology. The circular design
enables product to be evenly distributed throughout the unit, increasing
cooling uniformity. The round design eliminates all poorly filled corners.
A distinct advantage of the OP><FLO cooling process is the compact
footprint, or base size. Most system installations encounter
limited space situations and the minimal footprint with
OP><FLO coolers provide invaluable versatility in system design.
The Simple Excellence of the OP><FLO cooler is in
its highly efficient design which produces a uniformly cooled product
with a low operating and installation cost compared to other conventional
type coolers.
