What are the objects of cold chain transport monitoring?

Nowadays, cold chain transportation monitoring vehicles can often be seen on the road, but do you know what is in the vehicle? What do you know about cold chain transport monitoring? The following follows a long series of Xiaotong to introduce to you:



Cold chain logistics objects mainly include the following types:



(1) Primary agricultural products: vegetables, fruits, meat, poultry, eggs, aquatic products, and flower products.



(2) Processed foods: frozen foods; cooked foods such as poultry, meat, and aquatic products; ice cream and dairy products; chocolate;



(3) Other products: pharmaceuticals, biological products, etc.



Different target commodities have different requirements for cold chain logistics depending on their own quality, level of placing on the market, and circulation areas. For example, in terms of quality requirements, the international market or high-end market is generally more stringent than the domestic market or the low-end market requirements; the remote market has high requirements due to the long distance, transportation, temperature and other factors that make the product quality susceptible to the impact of home. Delayed consumer products should be kept fresh, processed, and refrigerated so that these products can be supplied to the consumer market or raw material processing market in a timely manner.



The temperature required for different target commodities varies, and the temperature required for frozen livestock and poultry meat, general aquatic products, frozen food, and ice cream is below 18°C; the temperature required for individual products (for example, fatty fish) is one. 30'C or less. Most of the rhizomes and leafy vegetables are suitable for storage at temperatures close to the freezing point. The storage temperature of most vegetable fruits native to temperate and cold regions is around 0°C, for example, apples, pears, peaches, cauliflower, celery, etc.; Most fruits and vegetables grown in tropical and subtropical regions require higher temperatures than OC.



For example, Xiangyan is 13C, mango is 101c, cucumber is 12C-13C, green pepper is 9C-12C, etc. Even the same variety has different temperature due to different maturity. For example, the transport temperature required for green tomatoes is 13C - 21C. Red tomatoes The required transport temperature is VC-101C. Various flowers have different storage temperatures. In general, the suitable temperature for flowers originating in temperate zones is OC-1C, and the suitable refrigeration temperatures for tropical and subtropical flowers are 70-15°C and 4C-7C, respectively. The required temperature for pharmaceuticals is OC-10C.



Cold chain transport monitoring is an important part of cold chain logistics. The cost of cold chain transportation is high, and it also contains more complex technologies for mobile refrigeration and incubator manufacturing. Special attention must be paid to continuous refrigeration in the transportation process because of microbial activity. Both the respiration and the respiration increase with the increase of temperature. If the links in the transportation can not guarantee the continuous refrigerating conditions, then the goods may begin to rot in this link. When transporting, the transportation method should be determined according to the type of cargo, the season of transportation, the distance of transportation, and the place of delivery. In the process of transportation, try to organize direct transportation from door to door, increase the speed of transportation, and the temperature must comply with regulations. In order to maintain the refrigerated temperature of frozen goods, they can be stacked compactly. Fruits, vegetables and other goods that require ventilation and heat dissipation must maintain a certain gap between the shipments to ensure that the goods are in good condition.
