With the large number of cold chain logistics in China, refrigeration equipment such as refrigerated trucks, cold storages and freezers began to be laid in large quantities. However, some problems have arisen during the use. According to media reports, there is such a woman in Linyi. When she drinks milk for her children, she finds that there is a blocky substance inside the fresh milk transported by the refrigerated truck. According to the personnel of the distribution station, this is caused by the problem of the refrigerator in the logistics distribution truck. In the end, it is the failure of the refrigerator.
An encyclopedia refrigerator is defined as a machine that transfers heat from a cooled object with a lower temperature to an environmental medium to obtain a cold amount. Refrigerators are widely used. Whether it is the low-temperature production environment required by the industry, or the demand for suitable temperature in plants in agriculture, or the storage of low-temperature storage in food and pharmaceutical industries, there must be a refrigerator. What we are going to talk about today is the refrigerator used in the food industry.
Refrigerator in storage process
China's modern machinery refrigeration industry started later than foreign countries, so some advanced core technologies have been firmly controlled by foreign countries. China is limited by international forms, and has formed a status quo that can not introduce high-tech refrigeration and technology. Therefore, strengthening independent research and development has become the key to the rise of the refrigeration industry.
Earlier, China's 16 electric power companies successfully developed the first gas bearing Stirling refrigerator engineering products through investment in scientific research and development funds and manpower. The chiller is a chiller with the highest efficiency and longest life under the same cooling capacity. It can provide a cold source for food refrigeration such as low temperature bio-refrigerators and oxygen/nitrogen machines. The refrigeration technology of gas bearing Stirling refrigerator has only been mastered in the hands of a few countries. The research and development has made breakthroughs in many fields such as multi-arm leaf spring damper, high-efficiency linear motor and high-efficiency heat exchange at cold end, achieving high-end chiller. Localization of products.
Refrigerator during transportation
The storage of food and food raw materials is not only related to storage, but also related to logistics and transportation. The above mentioned fresh milk was found to be agglomerated because of the failure of the refrigerator on the conveyor. In order to cope with this phenomenon, some enterprises install sensors and temperature alarm devices on the transport vehicles. Once the temperature around the food is unsuitable for food storage during transportation, an alarm will be issued and the data will be uploaded.
In addition, when transporting the “last mileâ€, there are often few items that need to be transported by the cold chain, and they are extremely scattered. In this case, the incubator + ice pack is used, the packaging cost is high, and the temperature is difficult to control; when the refrigerated truck is used, the transportation cost is too high and the efficiency is low. Faced with this phenomenon, some enterprises have improved the chiller, removed the evaporator and condenser on the refrigerant, and used the new compressor design, so that the chiller can rotate at any time while reducing the volume, and freely bump. It is suitable to be placed in the back seat of the battery car for transportation.
The chiller equipment suitable for the food industry can be derived from various types according to the type of refrigeration, such as water-cooled chillers, screw chillers, and air-cooled chillers. In addition, the chiller is also closely following the wind energy conservation and environmental protection, mainly reflected in two aspects. First, equipped with a good compressor to improve energy efficiency, it is reported that good compressor equipment can increase energy efficiency by 20% to 30% to achieve energy saving; second, intelligent regulation, and some refrigerators are equipped with intelligent control systems, which can adjust themselves according to load changes. To achieve thrift energy consumption.
As the weather gets hotter, more and more foods have a strong demand for storage and production conditions, and the chiller as the backbone of refrigeration equipment is a good time to show their talents. China's refrigeration equipment-related production enterprises in the R & D and production of refrigeration machines, but also need to grasp the market demand pain points, accurate research and development direction, and strive to produce more reliable refrigeration equipment in the sales process.
