摘要
A pasteurization/homogenization arrangement with regeneration brings raw milk or other liquid food product up to a few degrees below a UHT pasteurizing temperature. The product is denaturized at 175° F. so that proteins do not deposit out. The product proceeds through a product-product regenerative heat exchanger where it emerges at about 260°. Here a homogenizer serves a timing pump and avoids the need for an additional pump or flow meter for the UHT stage. The homogenized product proceeds to a water-product heater to heat the product to 280° F. The temperature differential at any reference point in the heater and the regenerative heat exchanger is below 20°, and the ratio of rate of water flow to product flow in the heater is below about 3:1. More efficient homogenization is achieved than at the conventional temperature (175° F.).
