Raw product from the extractors flows to the product balance tank. The product is then transported by the flow meter controlled timing pump through the raw regenerator section where it is pre-heated by sterile product from the sterile regenerator. Pre-heated raw product enters the heater section from the timing pump and is heated to the sterilizing temperature before entering the holding tube. Processed product from the holding tube enters the sterile regenerator section where it is pre-cooled by incoming product from the raw regenerator. Processed product then flows to the cooler section and is cooled to filling temperature. A backpressure device insures proper pressure relationships in the heat exchangers. From the cooler section, processed product flows through a set of divert valves to an aseptic surge tank or back to the balance tank. The processed pulp can be used directly or stored for future use. If used directly, it is blended with processed juice at the filler inlet to yield the desired product.

Water from the water balance tank is used for system sterilization prior to running product. The sterilization water is recycled through the system and returned to the balance tank. The sterilization water cooler section cools the sterilizing water below the flash point prior to being returned to the balance tank.
