  • Patent number: 11229186
    Abstract: A method for cooling milk in a milking arrangement, and a milk cooling apparatus of the milking arrangement that has a coolant circuit for heat exchange between milk and a coolant and a refrigerant circuit for heat exchange between a refrigerant and the coolant, where the method includes controlling the refrigerant circuit to maintain a predefined temperature range, receiving a first signal relating to commencement or increase of a milk flow from a milking system of the milking arrangement, starting or increasing circulation of coolant in the coolant circuit, and leading the milk flow through the milk cooling apparatus.

  • Patent number: 10537088
    Abstract: A system for storing and cooling milk includes a cooling tank to store milk, a first sensor monitoring the filling level of milk in the cooling tank, and a cooling system cooling the milk in the cooling tank including a cooling device, a second sensor, and a control device. The cooling device includes an evaporator, a varying-capacity modulated scroll compressor connected with its suction side to the evaporator, a condenser connected to the high pressure side of the compressor, and an expansion valve interconnected between the condenser and the evaporator. The second sensor monitors a parameter indicative of the pressure at the suction side of the compressor. The control device is operatively connected to the first sensor to receive the monitored filling level, the second sensor to receive the monitored parameter, and the compressor to control the capacity thereof in response to the monitored filling level and the monitored parameter.

  • Patent number: 10470430
    Abstract: A cooling system for cooling a flow of milk includes a first and a second refrigeration system; a first and a second intermediate coolant circulating system; and a line manifold interconnectable between the first and second intermediate coolant circulating systems, wherein coolant in the first intermediate coolant circulating system is in heat exchange connection with the first refrigeration system in a first heat exchange section and coolant in the second intermediate coolant circulating system is in heat exchange connection with the second refrigeration system in a second heat exchange section. The cooling system is reconfigurable between first operation configuration providing two-stage cooling of the flow of milk and a second operation configuration providing one-stage cooling of the flow of milk.
