Before hot filling of the stainless steel condenser, an ultra-high temperature tubular condenser is required for instantaneous sterilization, and the sterilization temperature is usually 125°C ~ 137°C. Because the nutrients contained in milk beverages, such as protein, starch, material wealth, coking, gelatinization, and pasteurization, the side walls that appear scaled in the tubular condenser product seriously affect the heat exchange efficiency of the heat exchanger , Increase the sterilization machine, thereby affecting the productivity of the sterilization machine, increasing the cleaning frequency of energy consumption.
