Features and Working Principle of the Cube Ice Machine

Feb. 25, 2021

An ice machine is a refrigeration machine that produces ice by passing water through an evaporator cooled by the refrigerant of the refrigeration system. Ice machines are often used in the modern art of living, but many people do not know much about them. The next ice machine supplier will introduce you to the characteristics and working principle of the cube ice machine.

The cube ice machine is a fully automated ice maker with four leading technologies: ice thickness self-regulation, environmental temperature self-adaptation, ice automatic compensation level stabilization and auxiliary condensation pressure stabilization system.

Feature of Cube Ice machine

1.The model is compact, small footprint put any places beautiful;

2.SUS304 stainless steel material, in line with food hygiene standards;

3.Design of magnetic seal for door panel, good heat preservation effect;

4.The main parts of the imported equipment, ensure quality.

The working principle of the refrigeration machine 

1.Storage tank of chilled water with a pump to continuously circulate through the plate or compartment of the evaporator;

2.Compressor operation after the suction - compression - exhaust - condensation (liquefaction) - throttling - and then in the evaporator to -10 to -18 degrees of low-temperature evaporation heat absorption vaporization. Chilled water in the 0-degree water temperature in the lower temperature evaporator surface condensation into ice. When the ice layer condenses to a certain thickness, the evaporating temperature of the refrigerant reaches the set temperature of the temperature control, then the defrost solenoid valve is switched on and the heat pump is often used to defrost the ice. Then the next cycle is realized. The next cycle is achieved.

Ice making cycle 

The water automatically enters a reservoir through a supplemental water valve and is then pumped through a flow control valve to a manifold head where it is sprayed evenly onto the surface of the ice maker and flows like a curtain over the walls of the ice maker, where the water is cooled to freezing point and the water that has not been frozen by evaporation flows through a porous tank into the reservoir and starts the cycle again.

Ice extraction cycle 

When the ice has reached the required thickness (the thickness can be chosen by the operator/user), the hot air from the compressor is redirected back into the walls of the ice maker to replace the low temperature liquid refrigerant. This forms a thin film of water between the ice and the evaporation tube wall, which will act as a lubricant when the ice falls freely by gravity into the trough below. The water produced during the ice harvesting cycle is returned to the reservoir through the porous tank, thus also preventing wet ice from being discharged from the machine.

Refrigeration machine condensation

Air-cooled, water-cooled or evaporative condensers are available. Evaporative condensers are installed above the ice machine, water-cooled condensers are installed below the ice machine or below the refrigeration system, and air-cooled condensers are installed either together with the ice machine or outdoors, depending on the situation. If required, water-cooled condensers can be used on boats or at the shore, using seawater for cooling. Evaporative cooling can be used where the ambient air temperature is high but is not suitable for use with water or air-cooled refrigeration for efficiency and economy reasons.
