Continuous-flow type apparatus for pasteurizing batches of product

摘要

A continuous-flow type pasteurization apparatus for pasteurizing batches of product. The apparatus has a product conduit that defines a continuous flow passage with a heater in heat exchange relation with one section of the conduit to heat the product to pasteurizing temperature as it flows therethrough and cooling coils and refrigeration coils in heat exchange relation with other sections of the product conduit to cool the product. A positive displacement type inlet pump is provided for pumping unpasteurized product from a container to the inlet end of the product conduit and a positive displacement type outlet pump is provided for pumping product from the outlet of the product conduit to a container for pasteurized product. A cleaning system is provided including a cleaning pump for pumping cleaning solution to and from cleaning fluid supply and return fittings located adjacent the inlet and outlet fittings of the product conduit. Transfer hoses connected to the inlet and outlet fittings of the product conduit can be selectively connected to the inlet and outlet product pumps to pump product through the product conduit, or to the cleaning supply and return fittings to pass cleaning fluid through the product conduit.
