1. What is a flake ice machine

Flake ice machine is a kind of ice machine. According to the water source, it can be divided into fresh water flake ice machine, sea water flake ice machine, and generally 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 slices is irregular, and the diameter is about 12 to 45 mm. Flake ice has no sharp edges and corners, and will not stab frozen objects. It can enter the gap between the objects to be cooled, 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 refrigeration, so it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling and so on.

2. Types of flake ice machine

 1. Classification of daily output of products:

1. Large-scale flake ice machine (above 20 tons)

2. Medium-sized flake ice machine (3 tons to 20 tons)

3. Small flake ice machine (0.5 tons to 3 tons)

2. Classification according to the nature of the water source:

1. Fresh water flake ice machine

Fresh water titles and instant use of fresh water as a water source to produce flake ice

2. Sea water flake ice machine

The flake ice machines that take sea water as a water source are mostly used for nautical purposes. The marine flake ice machine is designed for marine ice making operations. It adopts a semi-enclosed deepened oil tank piston compressor and a marine seawater condenser, which can not be affected by the rocking of the ship, and is not corroded by seawater.

Third, whether the classification can be moved

1. Containerized flake ice machine

The flake ice machine can be placed in a 20-foot or 40-foot container, which saves capital construction expenditure and is convenient to move and maintain.

2. Non-container flake ice

Containerized classification

The flake ice machine can be placed in a 20-foot or 40-foot container, which saves capital construction expenditure and is convenient to move and maintain.

3. Wide application of flake ice machine

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

1. Fishery:

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

2. Aquatic product processing:

Flake ice can reduce the temperature of processing media, washing water, and aquatic products, prevent bacterial growth, and keep aquatic products fresh during processing.

3. Food processing:

For example, when mixing or adding cream twice in bread production, use flake ice to quickly cool down to prevent fermentation.

4. Poultry meat processing:

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

5. Vegetable distribution and preservation:

Nowadays, in order to ensure the edible safety of vegetables, fruits, and meats, more and more physical methods are used to control temperature in the storage and transportation of products. Flake ice has a rapid cooling effect, which can create a low temperature and high humidity environment to ensure that the subject is not damaged by bacteria.

6. Pharmaceutical industry:

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

7. Concrete mixing:

Flake ice is directly used as the source of water in concrete mixing, with a ratio** of 80%. It can provide an efficient and easy-to-control cooling effect. The concrete mixed at a constant temperature will not crack due to physical deformation caused by temperature, thus ensuring the quality and safety of the project. Flake ice concrete cooling systems are widely used in high-quality large-scale projects around the world, such as large dams, high-grade highways, high-rise buildings and nuclear power plant construction projects, etc...

8. 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 continuous expansion of ice in the chemical industry is determined. In the production and synthesis process of azo-reactive pigments and dyes, diazotization, coupling and condensation are the necessary synthetic processes for production, due to the release of diazotization, coupling and condensation reactions. A large amount of heat is generated, and the ideal reaction conditions should be 0-5 degrees Celsius, so a large amount of ice must be added to cool the temperature during the chemical reaction process to ensure the quality of the product.

Fourth, the principle of flake ice machine

1. Vertical evaporator for flake ice machine

The evaporator of the flake ice machine is a vertically erected barrel structure, which is composed of the ice blade, the main shaft, the sprinkler tray, and the water tray, which are the main components of ice making. Driven by the reducer, they slowly rotate counterclockwise.

2. Principle of ice making

The water enters the water divider from the water inlet of the evaporator of the flake ice machine, and the water is evenly sprinkled on the inner wall of the evaporator through the sprinkler pipe to form a water film; the water film exchanges heat with the refrigerant in the evaporator flow channel, and the temperature is rapid When lowered, a thin layer of ice is formed on the inner wall of the evaporator, which is broken into pieces of ice under the squeeze of the ice skates, and falls into the ice storage through the ice drop. Part of the uniced water flows back into the cold water tank from the water return port through the water tray, and then passes through the cold water circulation pump.

3. Ice making cycle

Through the supplementary 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 on the surface of the ice maker and flows through the ice maker like a water curtain On the wall surface, the water is cooled to the freezing point, and the water that has not been evaporated and frozen will flow into the water storage tank through the porous tank, and the cycle will restart.

4. Ice picking cycle

When the ice reaches the required thickness (under normal circumstances, 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 film of water is formed between the ice and the wall of the evaporation tube. This film of water will act as a lubrication when the ice falls freely into the groove below by gravity. The water produced during the ice picking cycle will return to the water storage tank through the porous tank, which also prevents wet ice from being discharged by the machine.

5. Refrigerator condenser

It can be realized with air-cooled, water-cooled or evaporative condenser. The evaporative type is installed higher than the ice machine, the water-cooled condenser is installed under the ice machine or under the refrigeration system, and the air-cooled condenser is installed in the ice machine according to the actual situation. It can also be installed outdoors. If necessary, water-cooled condensers can be used on ships or on shore, using sea water for cooling. Evaporative cooling can be used when the ambient air temperature is relatively high, but from the perspective of efficiency and economy, it is not suitable for water-cooled or air-cooled cooling.
