Abstract: The present invention relates to a portable milk can cooling apparatus employing a removable flexible wrap-around jacket with closed-loop glycol circulation for rapidly cooling and maintaining the temperature of milk stored in conventional milk cans. The apparatus comprises a portable refrigeration unit mounted on a mobile frame and including a compressor, condenser, evaporator, glycol circulation pump, glycol circulation tubes, a monitoring-control unit, and a closed-loop secondary glycol refrigerant circuit. A removable flexible wrap-around jacket is configured to substantially conform to the external surface of the milk can and is adapted to circulate chilled glycol for indirect heat exchange, thereby reducing the temperature of the milk without direct contact between the coolant and the milk. The monitoring-control unit regulates the refrigeration cycle and glycol circulation to maintain a predetermined milk storage temperature. In one embodiment, the apparatus further comprises glycol inlet and outlet non-return connectors incorporating automatic self-sealing spherical ball valve assemblies configured to automatically seal the connector openings upon disconnection of the wrap-around jacket, thereby substantially preventing glycol leakage, preserving the integrity of the closed-loop circulation system, and enabling rapid and spill-free attachment and removal of the jacket. The invention provides a compact, portable, hygienic, and energy-efficient cooling solution suitable for dairy farms, village milk collection centres, milk transportation vehicles, and other decentralized dairy applications, without requiring modification of conventional milk cans or permanent refrigeration infrastructure.
