"Flake ice machine" knowledge

Definition: Machine for continuous production of ice sheets.

Flake ice machine is a type of ice machine, and it is generally an industrial ice machine. The produced ice is in sheet form. Ice flakes can be made from fresh water or brine. Slices of ice are thin, dry, loosely-shaped white ice with a thickness of 10 mm to 15 mm. The shape of the product is irregular, with a diameter of about 12 to 45 mm. Slices of ice are not sharp and angular and will not hurt frozen objects. Can enter the gap between the cooled objects, reduce heat exchange, keep the temperature of the ice, and have a good moisturizing effect. The ice sheet cooling effect is excellent, and the cooling capacity is large and rapid. Therefore, it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling, and the like.

Ice mechanism ice operation principle

1, the amount of ice needed for salt water (in jargon is called dosing) to see how much the amount of ice modulation pump (plunger pump) automatic adjustment.

2, the body of the ice maker is divided into two-cavity in vitro cavity of a certain density of copper tubes! The technical term is called (vaporization chamber) is the saying that the refrigeration thing.

3, the outer cavity is a very regular round stainless steel cavity center with a three-leaf scraper and the inner wall can adjust the distance of 3 mm. There are several sets of evenly distributed copper nozzles above the skate!

4. The working principle is that the plunger pump will add salt water through a few filters to spray 0.2 kg of water evenly onto the surface of the inner cavity and the outer surface of the cooling surface will instantly form a 3-mm thick ice surface. Under the action of the rotating ice skate, the freshly prepared ice is dropped into small storage bins. The principle of civil ice machine is basically the same! The inner cavity is a rotating ice cube box.

The working principle of the chiller is as follows: 1. The chilled water of the storage tank is continuously circulated through the plate or grid evaporator; 2. The compressor is operated through suction-compression-exhaust-condensation (liquefaction)-throttling - At a low temperature of -10 to -18 degrees in the evaporator, endothermic vaporization. The chilled water continuously condenses into an ice layer on the surface of a cooler temperature evaporator at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness When the evaporating temperature of the refrigerant reaches the set temperature of the temperature control, the defrosting solenoid valve is turned on to use the heat pump to deice. Then the next cycle is realized.

Ice cycle:

By replenishing the water valve, the water automatically enters a water storage tank, and then the water flows through the water flow control valve to the diverter head, where the water evenly sprays onto the surface of the ice maker and flows through the ice maker like a curtain of water. On the wall, the water is cooled to the freezing point, and the water that has not been evaporate and frozen will flow into the water storage tank through the porous tank and restart the cycle work.

Ice picking cycle:

When the ice reaches the required thickness (the thickness can be arbitrarily chosen by the operator/user), the hot gas discharged from the compressor is re-introduced into the wall of the ice maker instead of the cryogenic liquid refrigerant. In this way, a film of water is formed between the ice and the evaporation tube wall. This layer of water will act as a lubricant when the ice falls freely into the groove below by gravity. The water produced during the ice-picking cycle will return to the water reservoir through the porous tank, which also prevents the wet ice from being discharged by the machine.

Refrigerator condensation:

With air-cooled, water-cooled or evaporative condenser. The evaporative system is installed above the ice machine. The water-cooled condenser is installed under the ice machine or below the refrigeration system. The air-cooled condenser is installed to fit the ice machine according to the actual situation. It can also be installed outdoors. If required, the water-cooled condenser can be used on board or on the coast and cooled with seawater. Evaporative cooling can be used at high ambient air temperatures, but is not suitable for water or air-cooled refrigeration in terms of efficiency and economics.
