PROBLEM TO BE SOLVED: To provide a device and method for heating sterilization of a liquid food, capable of avoiding damage to a food product due to direct contact with a high-temperature heating medium, and reducing residence time of the food in a high-temperature region with reduced time required for heat exchange, so that damage to the food due to high temperature can be reduced.SOLUTION: The device for heating sterilization for a liquid food includes: a pump 2 for the liquid food for feeding a concentrated liquid food 1; a coil-type tubular heat exchanger 7 for heating having a flow channel 6 with an inlet 3, an outlet 4, and a tubular heat exchange wall 5; a heat exchanger 12 for cooling having a flow channel 11 with an inlet 8, an outlet 9, and an exchange wall 10; a storage tank 14 for the liquid food product, which temporarily stores the liquid food product 13 reduced by cooling; a pump 16 for dilution water for feeding dilution water 15 for sterilization cooling; and a fourth flow channel 24 which allows a discharge port 22 of the pump 16 for dilution water to communicate with a confluent point 23 of a second flow channel 19. |
