An ice machine is a refrigeration machine that produces water by cooling water from a refrigeration system through an evaporator. According to the principle of the evaporator and the generation process, the shape of the generated ice is also different. Generally, the ice machine is divided into a particle ice machine, a flake ice machine, a plate ice machine, a tube ice machine, a shell ice machine, etc. according to the ice shape. .

Type of ice

According to the use and characteristics of ice itself, ice is mainly divided into: tube ice, block ice, granular ice, flake ice (fresh water / sea water), plate ice (fresh water / sea water), transparent ice, ice water. No matter which type of ice, it is determined by its characteristics.

According to the shape of ice, it can be divided into: scaly ice machine, snowflake ice machine, ice machine, ice machine, ice machine (can be divided into small ice machine and industrial ice machine), ice machine, Granulator, tube ice machine, bullet ice machine,

Ice machine concept

Using a refrigeration system, with a water carrier, after passing through a certain device under power-on conditions, the device (machine) that manufactures ice is called ice making.

The role of ice

The role of ice is divided into three types: one for cooling, two for eating, and three for artificial scenes for viewing.

working principle

1. The chilled water of the water storage tank is continuously circulated through the plate or the compartment evaporator by the water pump;

2. After the compressor is operated, it is subjected to suction-compression-exhaust-condensation (liquefaction)-throttle--in the evaporator, and is vaporized by evaporation at a low temperature of -10 to -18 degrees. The chilled water continuously condenses into an ice layer on the surface of the lower temperature evaporator at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature control set temperature, the defrosting solenoid valve is often turned on and the heat pump is used to de-ice, and the next cycle is realized.

Ice making cycle

By replenishing the water valve, the water automatically enters a water reservoir, and then the water is pumped through the flow control valve to the splitter head, where the water is evenly sprayed onto the surface of the ice maker, flowing 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 frozen by evaporation will flow into the reservoir through the porous tank and resume the cycle.

Principle of operation

1 The water used for ice making needs to add salt (the jargon is called dosing) as much as the amount! See how much the ice pump is adjusted by the pump (piston pump).

2 The main body of the ice machine is divided into two chambers of a certain density of copper tubes in the outer cavity of the cavity! The terminology is called (evaporation chamber) is the thing of refrigeration.

3 The outer cavity is a very regular round stainless steel cavity center. The distance between a three-blade scraper and the inner wall can be adjusted by itself to 3 mm. There are several sets of evenly distributed copper nozzles above the ice skate!

4 The working principle is that the plunger pump sprays the salt-doped water through several filters to spray the 0.2 kg of water onto the surface of the inner cavity and then the cooling surface of the outer cavity instantly forms a 3 mm thick ice surface. Under the action of the ice skates, the newly prepared ice is broken into small pieces and dropped into the storage bin! The principle of the 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 water storage tank is continuously circulated through the plate or the compartmentalized evaporator; 2. After the compressor is operated, the suction-compression-exhaust-condensation (liquefaction)-throttle - further vaporization by evaporation at a low temperature of -10 to -18 degrees in the evaporator. The chilled water continuously condenses into an ice layer on the surface of the lower temperature evaporator at a water temperature of 0 degrees. When the ice layer condenses to a certain thickness When the evaporation temperature of the refrigerant reaches the temperature set temperature, the defrosting solenoid valve is turned on and the heat pump is used to de-ice. The next cycle is realized.

Ice making cycle:

By replenishing the water valve, the water automatically enters a water reservoir, and then the water is pumped through the flow control valve to the splitter head, where the water is evenly sprayed onto the surface of the ice maker, flowing 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 frozen by evaporation will flow into the reservoir through the porous tank and resume the cycle.

Ice picking cycle:

When the ice reaches the required thickness, the hot gas discharged from the compressor is redirected back into the ice collector wall 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 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 pass through the porous tank back into the water reservoir, which also prevents the wet ice from being discharged by the machine.

Flake ice machine

application

The flake ice machine has been widely used in aquatic products, food, supermarkets, dairy products, medicine, chemistry, vegetable fresh-keeping transportation, marine fishing and other industries. With the development of society and the continuous improvement of people's production level, the industry using ice is becoming wider and wider. The quality of ice is getting higher and higher. The requirements for "high performance", "low failure rate" and "health" of the ice machine are becoming more and more urgent.

1. Application in aquatic product processing: flake ice can reduce the temperature of processing medium, washing water and aquatic products, prevent bacteria from growing, and keep fresh in the processing of aquatic products.

2. Application of the processing of meat products: The flakes that meet the hygienic standards are mixed with meat and stirred. In order to achieve the purpose of cooling, preservation.

3. Application of food processing: For example, in the production of bread, when stirring or twice creaming, use a piece of ice to quickly cool down to prevent fermentation.

4. Application in supermarkets and aquatic products market: for the preservation of aquatic products, display, packaging, etc.

5. Application of vegetable processing: The process of harvesting and processing agricultural products and vegetables uses flake ice to reduce the metabolism of agricultural products and the growth rate of bacteria. Extend the shelf life of agricultural products and vegetables.

6. Application of long-distance transportation process: products such as ocean fishing and vegetable transportation that need to be cooled and preserved are more and more widely used in long-distance transportation to cool and preserve fresh flake ice.

7. It is also widely used in laboratories, pharmaceuticals, chemicals, artificial ski resorts and other industries.

8. Application in concrete engineering: When the concrete is poured in a wide range in the hot season, the pouring temperature of the concrete must be effectively and reasonably controlled. The flake ice + cold water stirring is the most effective way.

advantage

The flake ice has obvious advantages compared with the traditional type of briquettes (bulk ice) and snow flakes. It has the advantages of being dry, not easy to agglomerate, good fluidity, good hygienicity, large contact area with fresh-keeping products, and not easy to damage fresh-keeping products. In many industries, it is the preferred product to replace other types of ice. And has:

1. High ice making efficiency and small loss of cooling capacity

The automatic flake ice machine adopts the latest vertical inner spiral cutter ice-cutting evaporator. When making ice, the water inside the ice bucket is evenly distributed to the inner wall of the ice bucket to quickly freeze, and the ice is formed by the spiral. The ice knife cuts the ice and drops, so that the surface of the evaporator is allowed to be utilized, which improves the efficiency of the ice machine.

2, the quality of the borneol is good, dry and not bonded

The vertical evaporator of the automatic flake ice machine has a sheet ice thickness of 1-2 mm and dry irregular scaly ice, and has good fluidity. 3, the structure is simple, the floor space is small

Ferguson FIM series flake ice machine has fresh water type, sea water type, self-contained cold source, user self-contained cold source, and ice storage. Nissan's ice volume ranges from 500Kg/24h to 60000Kg/24h. Users can choose the right type of machine according to the use occasion and water quality. Compared with the traditional ice machine, it has a small footprint and low operating cost (no need for someone to take off ice and take ice).

Characteristics

1, direct low temperature, low ice temperature, up to -8 °.

2, the ice is dry and clean, the shape is beautiful, it is not easy to block, the fluidity is good, and the hygiene is convenient.

3, sheet-like structure, so the contact area with the cold collection is large, the cooling effect is wonderful.

4, sheet ice without sharp edges and corners, will not damage the surface of the cold collection, and is very conducive to storage and transportation.

5, the thickness of ice can be reached 1mm -2mm And no need to crush the ice machine, you can use it at any time.

6, the surface area can reach more than 1500 square / ton.

Brief

As the ice machine market is still in the initial stage of development, our customers and even our distributors are very familiar with the ice machine, and stay in the initial stage of understanding. One of the most obvious signs is that many ice machines do not have instructions for ice production under different seasons and different ambient temperature conditions, so many misleading and mis-purchasing behaviors have occurred. So how can we correctly guide the consumer's consumption behavior? Here is our experience to provide a more professional reference for the majority of customers who use ice.

Ice cube demand

From an empirical point of view, in general, Chinese restaurants: 0.5kg ice cubes per seat; Western restaurant: 1kg ice cubes per seat; hotel rooms: 1kg ice cubes per room; pearl milk tea, foam black tea, 1kg of ice can supply 7-8 cups; sand ice and shaved ice can supply about 4 cups per kilogram. Knowing the above data, friends in the restaurant industry can make reasonable choices based on their size and forecast of turnover.

Understanding of the ice production capacity of the ice machine in summer: When entering the summer, the water temperature and the ambient temperature increase significantly, and the rise of the water temperature is equivalent to extending the ice making time of each ice (because the water has a freezing point of 0 ° C, the high temperature is required. The ice-making water is cooled to 0 °C, which is lower than the normal temperature water, and the ambient temperature is too high. The air-cooled ice machine with air for cold and heat exchange has a large amount of ice production. Falling is an unavoidable and serious fact.

Ice machine use precautions

First, the ice machine should be installed away from the heat source, without direct sunlight, and the ventilation is good. The ambient temperature should not exceed 35 degrees Celsius to prevent the condenser from dissipating heat and affecting the ice making effect. The floor where the ice machine is installed should be solid and flat, and the ice machine must be level, otherwise it will cause no ice and noise during operation.

Second, the gap between the back and left and right sides of the ice machine is not less than 30cm, and the top clearance is not less than 60cm. An independent power supply should be used. The special line is powered and equipped with a fuse and a leakage protection switch, and it must be grounded reliably.

Third, the water for the ice machine should meet the national drinking water standards, and a water filtration device should be installed to filter the impurities in the water to avoid clogging the water pipes and polluting the water tank and the ice mold. And affect the performance of ice making.

Fourth, when handling the ice machine, carefully handle it to prevent severe vibration. The handling inclination should not be less than 45 degrees. After long-distance transportation, the ice machine should be placed for 2-6 hours before the mechanism ice can be opened.

Fifth, when cleaning the ice machine, the power should be turned off. It is strictly forbidden to use the water pipe to directly align with the body. Use a neutral detergent to scrub. Do not use acidic or alkaline solvents to clean.

Sixth, the ice machine must unscrew the inlet hose head for two months to clean the inlet valve screen to prevent the sand mud impurities from clogging the water inlet, which causes the water intake to become smaller, resulting in no ice.

Seventh, the surface of the condenser must be cleaned every two months. Condensation and poor heat dissipation can cause damage to the compressor components. When cleaning, use a vacuum cleaner, a small brush, etc. to clean the condensed surface oil dust. Do not use a sharp metal tool to clean it to avoid damaging the condenser.

Eighth, the water pipes, sinks, storage refrigerators and protective film of the ice machine should be cleaned every two months. When not in use, it should be cleaned, and the ice mold and the moisture in the box should be dried with a hair dryer, and placed in a place free of corrosive gas and ventilated and dry, to avoid open storage.
