ABSTRACT:
A freezer machine includes a freezing vessel arranged to freeze an amount of water for ice or ingredients for ice cream or similar cold products introduced thereinto, a refrigeration circulation circuit including a compressor, a condenser and an evaporator coil arranged for thermal exchange with the freezing vessel, and a solenoid valve disposed within a bypass circuit connected in parallel with the refrigeration circulation circuit to supply therethrough the hot gas outflowing from the compressor directly into the evaporator coil when the solenoid valve has been energized. A power supply circuit for the freezer machine is designed to deactivate the compressor at a predetermined time before the end of ice or ice cream or cold product preparation, and to energize the solenoid valve in response to deactivation of the compressor.
