What Is a Flake Ice Machine?

The flake ice machine is a kind of ice maker. It can be divided into fresh water flake ice machine and sea water flake ice machine according to the source of water. Generally, it is mostly an industrial ice machine. Flake ice is thin, dry and loose white ice with a thickness ranging from 1.0 mm to 2.5 mm. The shape of the flake is irregular and the diameter is about 12 to 45 mm. The flake ice has no sharp edges and corners, and will not hurt frozen objects. Can enter the gap between the objects to be cooled, reduce heat exchange, keep the temperature of ice, and have a good moisturizing effect. Flake ice has excellent refrigeration effect, and has the characteristics of large and rapid cooling capacity. Therefore, it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling, and so on.

Foreign brands are more famous in China such as American SCOTSMAN, German MAJA, VOGT and so on. The major domestic manufacturers are Fujian Snowman, Yantai Ice Wheel and other companies. With the maturation of ice machine manufacturing technology, the flake ice machine industry is booming in China, completely breaking the previous situation of all dependence on imports.

Scotsman (United States) was born in the 1950s. Most of the evaporators are horizontal, and the ice making principle of the horizontal evaporator is also recognized as the most efficient ice maker. As a pioneer in the development of reliable and affordable home ice makers, research, innovation and customer service for over half a century have made us a truly global, authorized dealer and service network in more than 100 countries. The main manufacturer of household ice machines.

Vogt (R) US Vogt is one of the few tube ice maker manufacturers in the world. The company was founded in the 1930s. Outstanding research and development capabilities have won a number of patents, and since then improved the traditional ice making mode; and developed an ice making system that can produce both crushed and ice for users to choose from. With more than 70 years of professional experience and design capabilities, Vogt ice makers are widely used in various ice industry. Its excellent quality has been widely praised by users, but the high price makes its business always hover in the high-end market.

First, from the daily product classification:

1.Large flake ice machine

2, medium flake ice machine

3.Small flake ice machine

Classification from the nature of water sources:

1. Seawater flake ice machine

2.Fresh water flake ice machine

Third, whether the classification can be moved from

1.Container-type flake ice machine

2.Non-container flake ice

Flake ice is widely used in food processing, manufacturing, and concrete cooling.

Fishery : Seawater flake ice machine can be installed directly on the fishing boat, using seawater to make ice. Salvaged seafood can be quickly frozen and kept fresh. Fishery is one of the most important application areas of flake ice machines worldwide.

Aquatic product processing : Flake ice can reduce the temperature of processing media, cleaning water, and aquatic products, prevent the growth of bacteria, and keep them fresh during the processing of aquatic products.

Food processing : For example, when stirring or creaming twice in the production of bread, quickly reduce the temperature with sliced ice to prevent fermentation.

Poultry meat processing: During the processing of poultry and meat, a huge amount of heat is generated. Flake ice can be used for the cooling process of poultry meat, and at the same time, adjust the humidity and improve the quality of the product.

Vegetable distribution and preservation: Nowadays, in order to ensure the safety of eating vegetables, fruits and meat foods, more and more physical methods are used to control the temperature in the storage and transportation of products. The flake ice has a rapid cooling effect, which can create a low temperature and high humidity environment, thereby ensuring that the subject is not damaged by bacteria.

Pharmaceutical industry: In many biosynthesis and chemical synthesis experiments, a large amount of ice needs to be added to control the reaction speed and maintain the activity of the organism. Flake ice is hygienic and clean, and its cooling speed is fast. It is the most ideal cooling carrier in this industry.

Concrete mixing: flake ice is directly used as the source of water in concrete mixing, the proportion is up to 80%. Can provide efficient, easy-to-control cooling effect. The concrete stirred under constant temperature will not be cracked due to physical deformation caused by temperature, thereby ensuring the quality and safety of the project. Flake ice concrete cooling systems are widely used in high-quality large-scale projects worldwide, such as large dams, high-grade highways, high-rise buildings, and nuclear power plant construction projects, etc ...

Chemical dyes:

With the rapid development of the chemical product processing industry, the market's requirements for the quality and technology of chemical products continue to increase. Due to the physical characteristics of ice, the application of ice in the chemical industry has continued to expand. In the production and synthesis of azo-reactive pigments and dyes, diazotization, coupling, and condensation are necessary synthetic processes for production. Due to diazotization, coupling reaction, and condensation reaction, they are released. A large amount of heat is generated, and the ideal reaction conditions should be 0-5 degrees Celsius. Therefore, a large amount of ice must be added to cool the temperature during the chemical reaction to control the temperature to ensure the quality of the product.

Flake ice machine flake ice machine upright evaporator

The flake ice machine evaporator is a vertical barrel structure, which is composed of the main components of ice making, the ice knife, the main shaft, the sprinkler tray, and the water receiving tray . Driven by the reducer, they rotate slowly counterclockwise. ^[2]

Flaky ice mechanism

Water enters the water separation pan from the inlet of the evaporator of the flake ice machine. Through the sprinkler pipe, water is evenly sprayed on the inner wall of the evaporator to form a water film; the water film exchanges heat with the refrigerant in the evaporator flow channel, and the temperature is rapid Lowered, a thin layer of ice was formed on the inner wall of the evaporator, and it was crushed into pieces of ice under the squeeze of an ice knife, and fell into the ice bank from the ice drop. Part of the unfrozen water is returned to the cold water tank from the water return port through the water receiving tray and passed through the cold water circulation pump. ^[3]

Flake ice mechanism ice cycle

Through the make-up water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the diverter head, where the water is evenly sprayed onto the surface of the ice maker and flows through the ice maker like a curtain On the wall surface, the water is cooled to the freezing point, and the water that has not been frozen by evaporation will flow into the water storage tank through the porous tank and restart the cycle work.

Flake ice extraction cycle

When the ice reaches the required thickness (normally, the thickness of the ice is 1.5-2.2MM), the hot air discharged from the compressor is re-introduced into the wall of the ice maker to replace the low-temperature liquid refrigerant. In this way, a layer of water film is formed between the ice and the wall of the evaporation tube. This layer of water film 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 be returned to the water storage tank through the porous tank, which also prevents wet ice from being discharged by the machine.

Flake ice machine refrigerator condenser

Air-cooled, water-cooled or evaporative condensers are available. The evaporative type is installed higher than the ice maker, the water-cooled condenser is installed below the ice maker or the refrigeration system, and the air-cooled condenser is installed with the ice maker according to the actual situation Can also be installed outdoors. If required, water-cooled condensers can be used on board or on the coast, using seawater for cooling. Evaporative cooling can be used in high ambient air temperature, but from the perspective of efficiency and economy, it is not suitable to use water-cooled or air-cooled refrigeration.
