The same is the Nissan 1 ton ice machine. The price of the Nissan 1 ton tube ice machine is twice the price of the Nissan 1 ton flake ice machine. Why is the tube ice machine so much more expensive than the flake ice machine? The principle of ice making is somewhat different. The configuration of the flake ice machine is relatively simple. There is no de-icing system, and the ice system of the tube ice machine is much more complicated.1. Differences in ice-making principles lead to large price differencesThe ice produced by the flake ice machine has a rotating ice blade to roll and scrape the ice, and then transfer it into and out of the ice storage.The prepared ice does not need to be de-iced, eliminating the need for a de-icing system. Flake ice machines are naturally cheaper than tube ice machines.The ice produced by the tube ice machine needs to be de-iced. With an additional de-icing system and many accessories and protection devices, the price is naturally much more expensive.econd, the difference of the evaporatorThe flake ice machine evaporator technology is more mature, the structure is relatively simple, the flake ice machine is cheaper and more favored by the market, and the production and processing cost of the flake ice machine is lower.The structure of the evaporator of the tube ice machine is more complicated, and the production cycle is also longer.3. Ice machine configuration and power differenceThe same is a 1-ton ice machine, the power of the flake ice machine is 4.6kw, and the cooling capacity is 5.6kw. The tube ice machine needs 5.4kw and the cooling capacity is 8.1kw.Flake ice machines generally use Danfoss/Copeland scroll compressors. Tube ice machines, on the other hand, require a BITZER/Rifconn piston compressor.Tube ice machines require larger storage tanks, oil separators, oil storage tanks, solenoid valves, and complicated piping.To sum up, the tube ice machine is more expensive than the flake ice machine, mainly because the cost of the tube ice machine is much higher than that of the flake ice machine.

Whether it is better to choose the air cooler or the exhaust pipe for the cold storage, I found that many friends are very confused. Some confuse the air cooler with the air-cooled unit, and some just don’t know the choice. Is it better to choose the air cooler or the exhaust pipe for the cold storage? Let's take a look today.Generally, for high-temperature warehouses, we recommend using air coolers, which are easy to install. If it is a large-scale cold storage, when the outside height of the cold storage is high, if the internal machine adopts exhaust pipes, the installation is very inconvenient, and there are certain safety hazards. The cooling fan is easy to disassemble and assemble, and is suitable for high temperature warehouses.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              For low temperature cold storage or ultra-low temperature cold storage, it is recommended to use exhaust pipes for low temperature cold storage in the market. From a long-term point of view, the use of exhaust pipes, the cooling capacity in the refrigeration is uniform, energy saving and electricity saving, but there are also certain disadvantages, the price is relatively high, and the installation is inconvenient compared to the air cooler.Generally, in the low temperature cold storage of minus 18 degrees or minus 25 degrees, it is completely possible to use the air cooler, and there is no need to worry about the problem of frost, but if it is an ultra-low temperature cold storage, it is recommended to use the exhaust pipe. Of course, this is also closely related to the budget of the cold storage owner.Cold storage chooses cooling fan or exhaust pipe from the following points1. From the perspective of cooling effect:The cooling effect of the exhaust pipe is better than that of the previous fan. The exhaust pipe conducts heat and cold faster, especially the aluminum row is the most important. Therefore, in general, a cooler can be used for high temperature storage. We recommend using exhaust pipe for low temperature or ultra-low temperature storage. The distribution of the exhaust pipes is relatively balanced, so the cooling capacity is relatively uniform, which can achieve the effect of energy saving and electricity saving.2. From the scope of application:Because the exhaust pipe is a pipe type evaporator, it can lock the moisture very strongly. The air cooler will evaporate the moisture because of the wind, making the products in the warehouse shriveled and withered. Therefore, the exhaust pipe is suitable for products with more moisture, such as Ice cream, fruits and vegetables, etc., and the air cooler is suitable for dry goods, dried fresh, frozen meat, etc., so generally choose to install the exhaust pipe or the air cooler, mainly depends on which one matches your product.Third, from the perspective of the library body:If it is a large-scale cold storage, if the external height of the cold storage is relatively high, it is recommended to use a cooling fan for the internal unit. The air cooler is used more in the high warehouse because it is easy to disassemble and assemble.Fourth, from the perspective of economical application:Generally speaking, due to the cooling performance and production cost of the exhaust pipe, the price of the exhaust pipe is slightly higher than that of the air cooler, especially the aluminum exhaust pipe. Whether it is a pipe or a fan depends on the budget.

Advantages and disadvantages of quick freezing tunnelQuick-freezing tunnels are more and more used in production and living fields, and they have obvious advantages and disadvantages.1. Disadvantages of quick freezing tunnel:Since both ends of the tunnel are difficult to seal tightly, and there is air communication with the external environment, there may be problems in sanitation and cleaning for poorly designed quick-freezing tunnels, which may have a hygienic impact on food processing.The installation period of large-scale quick-freezing tunnels is slightly longer. For quick-freezing tunnels with large production capacity, larger workshop space is usually required. Wind-type quick-freezing tunnels may cause a small amount of water loss in food during production;2. The obvious advantages of quick freezing tunnel:Customized products according to process and hygienic requirements, it is easier to meet the requirements of production standards; can realize automatic control, no need for manual duty, save labor costs, continuous production, high production capacity, suitable for modern high-speed production lines, can be customized to be easy to clean and hygienic Product structure Quick-freezing and cooling operation costs are low. For quick-freezing and cooling of food, the operating electricity cost per kilogram is about 0.1~0.15 yuan (the electricity price may vary from place to place). Other cooling items cool down quickly and easily meet the process requirements. , Fast cooling, good food preservation effect, high quality and high value are locked.The appearance is clean and beautiful, and the products are elegant, which adds points to the corporate image. It is connected with the automated process to greatly improve the production efficiency; customized production is integrated with the supporting production process into a unified assembly line system;The difference between quick-freezing warehouse and quick-freezing tunnelQuick-frozen foods have the following advantages:1. The food stays in the cold storage for a short time, which is beneficial to improve the utilization rate and continuous production efficiency of the refrigeration equipment.2. Quickly reduce the food to below the temperature of microbial growth activity, which is beneficial to resist the growth of microorganisms and their biochemical reactions;3. Reduce the water separation in the cells, reduce the loss of juice during thawing, and avoid the formation of large ice crystals between cells;4. The time for concentrating solutes, food tissues, colloids and various components in contact with each other in the cell tissue is significantly shortened, and the harm of concentration is reduced to a minimum; The entry and exit of goods in the quick-frozen cold storage need to be realized manually. The food that needs to be quick-frozen is put into the cold storage, the refrigeration equipment is turned on, and the food is rapidly cooled and frozen; when the food is frozen, the refrigeration equipment is stopped, and it also needs to be manually The goods are moved out and transferred to a low temperature refrigerator or other place. The quick-freezing tunnel is also known as the tunnel-type quick-freezing machine. The principle is the same as that of the quick-freezing warehouse. The biggest difference is that the quick-freezing tunnel can realize continuous quick-freezing work and improve production efficiency.The quick-freezing warehouse is to quickly pass the food through its largest ice crystal formation area, and freeze quickly when the central temperature reaches -18 °C. Quick-freezing cold storage usually requires relatively large refrigeration equipment. The refrigeration capacity of the equipment is proportional to the quick-freezing capacity of the food and inversely proportional to the quick-freezing time. Quick-freezing cold storage is also called quick-freezing warehouse.The characteristic of quick-frozen food is to maintain the original nutritional value, color and aroma of the food to the greatest extent, that is to say, the quick-frozen cold storage is to ensure the maximum reversibility of the above-mentioned changes in the food during the freezing process. Food will undergo various changes during the freezing process, such as physical changes (volume, thermal conductivity, specific heat, dry consumption changes, etc.) chemical changes (protein denaturation, color change, etc.) cell tissue changes and biological and microbial changes Wait.
