Refrigerated containers - refrigerated containers refrigerated containers is a good thermal insulation, air tightness, and can maintain a certain low temperature requirements applicable to all types of perishable food products transportation, storage and special containers. Designed to maintain a certain temperature required for the transport of frozen goods or goods designed cryogenic containers. It is divided into concealed mechanical refrigerated containers with freezer and freezer no external mechanical refrigerated containers. Applicable load of meat, fruit and other goods. Refrigerated containers higher cost, higher operating costs, use should pay attention to the required technical condition and the temperature inside the cargo refrigeration system. Refrigerated containers - basic types of insulated containers refrigerated containers concealed external refrigerated containers refrigerated containers of liquid nitrogen and dry ice freezing plate refrigerated containers atmosphere refrigerated containers refrigerated containers - basic properties refrigerated containers reefer containers made of galvanized steel, container wall, floor, roof and doors made of metal composite panels, aluminum, stainless steel or polyester international container size and performance are standardized temperature range of -30 ℃ ~ 12 ℃, more versatile range is -30 ~ 20 ℃ Features: refrigerated containers having flexible handling, cargo transport temperature stability, cargo pollution, low loss, for use in a variety of vehicles, loading and unloading fast transit time is short, low transportation costs. According to transport refrigerated containers can be divided into two kinds of sea and land. Refrigerated Containers - Refrigerated Container Refrigerated Container characteristics can be used to transport a variety of means of transport from origin to point of sale, and "country to country" direct transport under certain conditions, can be used as cold storage activities can use use lifting FCL , efficient loading and unloading, transport costs are relatively low. Load capacity utilization high, flexible scheduling operations, the use of economic and strong. The new refrigerated container structure is more reasonable and advanced technical performance, have broad applicability. Refrigerated containers - General requirements for the use of refrigerated container Reefer ⒈ should be checked after loading the original quality of refrigerated or frozen goods, and are described in the manifest. ⒉ the packing process, should be strictly loading stacking principle, to avoid a short circuit caused by cold air cooling imbalances, reduce the cooling efficiency of the refrigeration apparatus. When ⒊ frozen goods long-distance transport, inside the set temperature and the actual temperature difference should not exceed 3 ℃. If delivery of cooling goods, its temperature error should be less than 0.5 ℃, preferably not more than 0.25 ℃. ⒋ container transport fresh fruit, vegetables, etc., should be to open a new outlet, for ventilation. But transporting frozen goods, the new outlet should be closed. ⒌ when transporting cartons of cooling goods, should be based on the outdoor temperature and humidity conditions, timely ventilation, keep the air inside the drying, the outer surface of the box to prevent condensation. Refrigerated containers - cool thermal performance refrigerated containers normally used for transporting frozen goods temperature should not be higher than -18 ℃. Typically foot refrigerated containers, with an average cooling rate of 31.3 ℃ / h (empty); but after loading, cargo due to the large heat capacity, will greatly slow down the cooling rate, and sometimes reaches the set temperature requirements needed 15-16h. If you purchase the temperature is high, the temperature required to achieve the set 2-3d. Refrigerated container box temperature rise, lower speed and load cargo box, and when after reaching the set temperature range -18 ℃ ± 3 ℃, should maintain its stable inside temperature. However, when calculating the freezer is not cooling when inside temperature, can be used as a standard value the following empirical formula to calculate 1) cooled cargo (without ventilation) 0.0054 * (tw-tn) ℃ / h 2) frozen goods 0.0067 * (tw -tn) ℃ / h where tw and tn respectively, outside temperature and inside temperature ℃.
