An ice maker is a kind of refrigeration mechanical equipment that generates water after being cooled by a refrigerant in a refrigeration system through an evaporator. The refrigeration system uses a water carrier to produce ice after passing through a certain device under the state of electricity. Depending on the principle of the evaporator and the production method, the shape of the generated ice cubes is also different; people generally divide ice machines into pellet ice machines, flake ice machines, plate ice machines, tube ice machines, shell ice machines, etc. .
Ice machines can be divided into commercial ice machines, household ice machines, and industrial ice machines.
The ice maker is divided according to the shape of the ice: there are granular ice (cylindrical, square, moon shape), snowflake type, scale ice, plate ice, tube ice, and newly developed spherical ice.
Particle ice is further divided into spray type, running water type and immersion type according to the ice making method.
Cylindrical ice is generally spray-type ice. This ice making method has a low freezing point, which can reach minus 20 ° C. The contact surface between the cylindrical surfaces is small, it is not easy to stick into agglomerates, and it is convenient to use ice. Cylindrical ice cubes have high hardness, low temperature, and crystal clear ice. They are suitable for cooling wines. Slow melting speed will not dilute the wine and affect the taste of the wine. The disadvantage of the cylindrical ice maker is that the ice production efficiency is low , Generally used to produce desktop small ice machines.
The temperature of scale ice is -6 ℃ ~ -12 ℃, which is most suitable for industrial processing and cooling of perishable goods. It is often used for seafood display in supermarkets. Large scale ice can also be used in cement plants, chemical plants, meat mills, marine fisheries, etc.
Refrigeration methods can be divided into: water-cooled ice maker, air-cooled ice maker.
Advantage 1. Direct low temperature, low ice temperature, can reach below -8 °. 2. It is dry and clean in ice, beautiful in shape, not easy to block, good fluidity, convenient and hygienic. 3. Sheet structure, so the contact area with the cold storage is large, and the cooling effect is very good. 4. Flake ice has no sharp edges and corners, will not damage the surface of the cold collection, and is very convenient for storage and transportation. 5. The thickness of ice can reach 1mm-2mm, and it can be used at any time without ice crusher. 6, the surface area can reach more than 1500 square / ton.
1. Application in the processing of aquatic products: Flake ice can reduce the temperature of processing media, cleaning water, and aquatic products, prevent the growth of bacteria, and keep fresh during the processing of aquatic products. 2. Application of meat products processing process: Flake ice that meets the hygienic standard is mixed with meat. In order to achieve the purpose of cooling and keeping fresh. 3． Food processing applications: For example, when stirring or re-buttering in bread production, quickly reduce the temperature with flake ice to prevent fermentation. 4． Application in supermarkets and aquatic product markets: for keeping freshness of aquatic products, display, packaging, etc. 5． Application of vegetable processing process: The use of flake ice in agricultural products and vegetable harvest processing reduces the metabolism and bacterial growth rate of agricultural products. Extend the shelf life of agricultural products and vegetables. 6. Application of long-distance transportation process: Products that need to be cooled and kept fresh, such as ocean fishing and vegetable transportation, are more and more widely used to reduce temperature and maintain freshness in long-distance transportation. 7. It is also widely used in laboratories, medicine, chemicals, artificial ski resorts and other industries. ⒏Application in concrete engineering: When the concrete is poured in a large area in the hot season, it is necessary to effectively and reasonably control the pouring temperature of the concrete. Flake ice + cold water mixing is the most effective way.
