Shanghai flake ice machine | Which Shanghai flake ice machine is the best?

[Wang Hui mobile phone - WeChat:] Shanghai flake ice machine | Which Shanghai flake ice machine is the best? It is a type of ice machine that produces ice in the form of thin flakes. Flake ice can be made from fresh water or salt water. Flake ice is thin, dry and loose white ice with thickness ranging from millimeters to millimeters, irregular surface shape, and diameter ranging from millimeters to millimeters.
Flake ice has no sharp edges and will not hurt frozen objects. It can enter the gap between the objects to be cooled to reduce heat exchange, maintain the temperature of the ice and have a good moisturizing effect. Flake ice has excellent refrigeration effect and has the characteristics of large and rapid cooling capacity, so it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling, etc.
1. Features:
Large contact area and rapid refrigeration
Due to the flat shape of flake ice, it has a larger surface area than other shapes of ice of the same weight. The larger the contact surface area, the better the cooling effect. Taking comparison as an example, the minimum surface area of one ton of flake ice is square meters, and other types of ice such as tube ice and granular ice can only provide up to square meters. Therefore, the refrigeration efficiency of flake ice is up to three times higher than that of tube ice and granular ice. .
, low production cost
The production cost of flake ice is very economical. It only takes about kilowatt-hour of electricity to cool water at 10 degrees Celsius into tons of flake ice.
Excellent food insurance
The texture of flake ice is dry, soft and has no sharp angles, which can protect the packaged food during the refrigerated packaging process. Its flat shape will minimize possible damage to the items being refrigerated.
Thorough mixing
Due to the rapid heat exchange process due to the huge surface area of flake ice, flake ice can quickly melt into water, take away heat, and add humidity to the mixture. Ice Bear Iberna flake ice machine
2. Shanghai flake ice machine | Which Shanghai flake ice machine has the best operating principle
The water used for making ice needs to be salted (called dosing in jargon). As for how much! The modulating pump (plunger pump) automatically adjusts depending on the amount of ice produced
The main body of the ice making machine is divided into two chambers: the outer chamber and the inner plate are made of copper tubes of a certain density! The professional term is called (evaporation cavity), which is what the saying goes for refrigeration
The outer cavity is a very regular round stainless steel cavity. There is a three-blade scraper in the center of the cavity. The distance from the inner wall can be adjusted by itself, usually in millimeters. In the ice blade There are several sets of evenly distributed copper nozzles above!
The working principle is that when the machine is turned on, the plunger pump passes water mixed with salt through several filters and sprays 1.0 kg of water evenly onto the surface of the inner cavity, and then the cooling surface of the outer cavity instantly forms a millimeter-thick ice surface. Under the action of the rotating ice blade, the freshly made ice is broken into small pieces and dropped into the storage bin! The principle of civilian ice making machines is basically the same!
The inner cavity is a rotating ice cube box
The working principle of the refrigerator is as follows
The chilled water in the water storage tank is continuously circulated by the water pump through the plate or divided evaporator
After the compressor is running, it goes through suction, compression, exhaust, condensation (liquefaction), throttling, and then evaporates and absorbs heat and vaporizes in the evaporator at a low temperature of - to - degrees. The chilled water continues to evaporate at a lower temperature at a water temperature of - to - degrees. The surface of the evaporator condenses into an ice layer. When the ice layer condenses to a certain thickness, the defrost solenoid valve is turned on after the evaporation temperature of the refrigerant reaches the set temperature of the temperature control. A heat pump is often used to remove ice. Then realize the next cycle
Ice making cycle

The water automatically enters a reservoir through the replenishing water valve, and then sends the water to the water pump through the flow control valve. The diverter head is where the water is sprayed evenly onto the surface of the ice maker like a water curtain. It flows through the wall of the ice maker. The water is cooled to the freezing point without being evaporated and frozen. The water that has not been evaporated and frozen will flow into the water storage tank through the porous groove
Re Start working cycle.
Ice harvesting cycle
When the ice reaches the required thickness (normally the thickness of ice is.-.), the hot air discharged from the compressor is redirected back into the ice maker wall to replace the low-temperature liquid refrigerant. . In this way, a thin film of water is formed between the ice and the wall of the evaporation tube
This water film will play a lubricating role when the ice falls freely into the groove below due to gravity. The water produced during the ice harvesting cycle will return to the water storage tank through the porous trough, which also prevents wet ice from being discharged by the machine.

It can be realized with air cooling, water cooling or evaporative condenser. The evaporative condenser is installed higher than the ice machine, the water-cooled condenser is installed below the ice machine or under the refrigeration system, and the air-cooled condenser is installed together with the ice machine depending on the actual situation. Installed outdoors.
If a water-cooled condenser is required, it can be used on a ship or on the coast to use seawater for cooling. Evaporative cooling can be used under conditions where the ambient air temperature is high but water-cooling or air-cooling refrigeration is not suitable from an efficiency and economic perspective.
