  • Method of operating and cleaning an apparatus for heat treating a liquid product
    Patent number: 4738302
    Abstract: Apparatus for heating-treating a liquid product comprising series-connected multi-tube heat-exchangers such as heating-up heat-exchangers 6, 12, and high temperature heat-exchanger 14 and cooling-down heat-exchangers 17, 18, 19, the heating-up heat-exchangers and cooling-down heat-exchangers being interconnected by means of a pipe system 25, 26; 34 for regenerative heat-exchange. The heat-exchangers being connected by means of connection members 13 having separate passages which connect the tubes of one heat-exchanger to those of the next heat-exchanger. The pipe system for regenerative heat-exchange being designed so that the quantity of heat to be transferred can be adjusted in order to adapt said apparatus to varying capacities.
