[0018] Compared with the prior art, the present invention provides a parallel extruder ice maker, which has the following beneficial effects:

[0019] 1. The parallel extrusion ice making machine is added with a cooling system. The cooling system exchanges heat in the intermediate heat exchanger. The coolant after heat exchange flows into the coolant tank and enters the evaporator through the solution pump to participate in the ice making process. The coolant output of the variable frequency compressor is controlled according to the temperature in the coolant tank, and the temperature of the coolant flowing to the evaporator is accurately controlled within a certain range.

[0020] 2. The parallel type extrusion ice making machine can compress the low-temperature and low-pressure refrigerant gas into the high-temperature and high-pressure refrigerant gas through the compressor provided; the refrigerant can release heat in the condenser, and the high-temperature and high-pressure refrigerant gas can be condensed into the medium-temperature and high-pressure refrigerant liquid. After the medium-temperature and high-pressure refrigerant liquid is throttled by the expansion valve and the filter, it can be turned into a low-temperature and low-pressure refrigerant gas-liquid mixture. The low-temperature and low-pressure refrigerant gas-liquid mixture flows through the intermediate heat exchanger, and after heat exchange with the coolant liquid, it can be turned into a low-temperature and low-pressure refrigerant gas. After the coolant liquid is heat exchanged, it is turned into a low-temperature coolant liquid.

[0021] 3. The parallel extruder ice maker can drive the belt and the pulley by starting the servo motor, thereby driving the two stirring sticks to rotate in the inner cavity of the refrigerant tank. At this time, the refrigerant in the inner cavity of the refrigerant tank can be stirred, so that the refrigerant re-entering the inner cavity of the refrigerant tank and the refrigerant remaining in the inner cavity of the refrigerant tank can be mixed evenly, thereby improving the refrigeration efficiency.

[0022] 4. The parallel extruder ice maker can drive the screw to rotate by starting the driving motor.

At this time, the bottom of the inner cavity of the refrigerant box can be cleaned, and blockage can be prevented when the refrigerant is discharged.

[0023] 5. The parallel type extruder ice maker can always push the card block outward through the fixed rod, and the first cleaning component can be connected to the movable block by cooperating with the card slot. The first cleaning component and the movable block can be separated by pressing the card block, so as to facilitate the removal and maintenance of the first cleaning component.

[0024] 6.
