Flake Ice Machine for sea water

Seawater flake ice machines,with marine oil tank compressor, aluminum brass anticorrosion seawater condenser,anti-swing design of water diversion device and return tankjcrced rotation ice blade design.Compact structure, directly installed on the fishing boat, use sea water to make ice,fall into the ship bunker,the fishing boat does not need to dock to hit ice, can reduce the load of the ship and save fuel cost greatly.

1. Standard Condition: Ambient Temperature 28°C, Water Inlet Temperature 20°C, Evaporating Temperature -25°C

Condensing Temperature 40°C.

2. Above parameters will be changed subject to the technical innovation without further notice.

The working principle

Through the make-up water valve, water is automatically entered into a water storage tank, and then the flow control valve through the pump to the water to the tap head, where water spray evenly to the ice on the surface, like water through the wall of ice and water is cooled to freezing point, and were not frozen water evaporation will through porous slot into the water storage tank, resume work cycle.

When THE ICE REACHES THE REQUIRED THICKNESS (THE thickness can be ARBITRARILY SELECTED by the OPERATOR/user), the HOT gas discharged from the compressor is REdirected back to the clamping wall of the ice maker to replace the low-temperature liquid refrigerant. This creates a thin film of water between the ice and the wall of the evaporation tube, which will lubricate the ice as it falls freely into the tank below by gravity. The water produced during the ice harvesting cycle will be returned to the storage tank through the porous tank, which also prevents the wet ice from being discharged by the machine.

1. The chilled water of the water storage tank is continuously circulated through the evaporator of plate or grid with a pump;

2, the compressor after operation by inspiration-compression - exhaust - condensation (liquefaction)- throttling - and then in the evaporator to -10 to -18 degrees of low temperature evaporation heat absorption vaporization. Frozen water in the temperature of 0 degrees Celsius constantly on the surface of the lower temperature evaporator ice. When the ice condenses to a certain thickness, the evaporation temperature of the refrigerant reaches the set temperature of the temperature control, that is, the defrosting solenoid valve is connected to the form of heat pump deicing, and then the next cycle.

Ice making process

Through the inlet valve and automatic water into a water storage tank, and then through the pump pumping to shunt, shunt tube will be low temperature water flow evenly into the liquid refrigerant cooled evaporator, water is cool to freezing point, these cooling to the freezing point of water will be frozen into ice, and not be evaporator frozen water and into the water storage tank, through the water pump to start work cycle.

When the ice reaches the required thickness, it will enter the de-icing state, and the high-pressure hot gas discharged from the compressor will be drained to the evaporator through the reversing valve to replace the low-temperature liquid refrigerant. This creates a film of water between the ice and the evaporator. This film removes the ice from the evaporator, and the ice falls freely into the ice storage tank below by gravity.
