Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of beverage processing, especially to a heat exchange tube bank for beverage processing, a heat exchange assembly and a sterilization equipment. BACKGROUND

[0002] Ultra-high temperature instantaneous sterilization is widely used in beverage and liquid food processing. According to whether the beverage directly contacts the heating medium, it is divided into indirect heating method and direct mixing heating method. Among them, the indirect heating method uses high-pressure steam or high-pressure water as the heating medium, and the heat is transmitted to the heated and sterilized beverage through the solid heat exchange wall.
