Full controlled fluidization method keeps the product constantly suspended above the belt in a cushion of air. The result is the immediate crust freezing and efficient core freezing of individual pieces, regardless of type, variety or condition of product. Up to few days or more continuous production without any drop in freezing efficiency, thanks to the effect of powerful ASR (Automatic Snow Removal) system. No more interruptions to defrost even when running double shifts, which again should present some daily savings of operating costs. Maximized freezing efficiency for each unique product, whether the product is heavy, light, soft, sticky or fragile, thanks to Variable speed control of all fans and belts, allowing on-the-fly optimization of air flow conditions.
