1. An ice-making machine, comprising:
a compressor;
a refrigerant;
a first evaporator;
a second evaporator connected to the first evaporator so that a protrusion of the second evaporator projects into a cell of the first evaporator;
a first fluid line connected to the compressor at a first end of the first fluid line and further connected to the first evaporator at a second end of the first fluid line, for carrying a first portion of the refrigerant to the first evaporator;
a second fluid line connected to the compressor at a first end of the second fluid line and further connected to the second evaporator at a second end of the second fluid line, for carrying a second portion of the refrigerant to the second evaporator; and
a first solenoid valve connected to the first fluid line, for selectively opening and closing the first fluid line to a flow of the refrigerant therethrough.
