The circuit of a gas-compression refrigerating unit in ice-cream making machines and/or ice-cream mixture pasteurizing machines has inserted therein a by-pass circuit controlled by one or more switching valves. During the cycle of pasteurization and/or sterilization of the ice-cream mixture and of the elements of the machine contacting said mixture (either liquid or frozen), the hot refrigerant gas coming from the compressor is diverted through the evaporator (by-passing both the condenser and expansion valve) so as to heat to a sterilization temperature...
A method of pasteurizing an edible liquid mixture congealable upon freezing to form a frozen congealed product in an apparatus for making ice cream or similar edible frozen congealed products wherein said apparatus includes a compressor having delivery and suction ports; a first conduit extending from the delivery port; a condenser connected on one side to the first conduit; an expansion valve; an evaporator, said evaporator being connected on an inlet side to the side of the condenser opposite the connection to the first conduit through the expansion va...
