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.
