Reefer container (Reefer container) refers to a good insulation, and can maintain a certain low temperature requirements, suitable for all kinds of perishable food transport, storage of special containers, The basic types of refrigerated containers are insulated containers, external refrigerated containers, internal refrigerated containers, liquid nitrogen and dry ice refrigerated containers, and frozen plate refrigerated containers. Speaking of refrigerated containers, we may think of fruits and vegetables and some fresh products will use refrigerated containers.
As everyone knows, refrigerated cabinets are also used in the export of dangerous goods by sea, because many dangerous goods are more sensitive to temperature, and their physical and chemical properties or product quality will be affected by external temperature. Some dangerous goods because of the nature of self-reaction or desensitization, high temperature transport is more dangerous.
For example, some food fungicides, dimethyl dicarbonate, 6.1 dangerous goods, their role is to carry out low temperature sterilization of red wine, get rid of the traditional medium and high temperature sterilization process, thus ensuring the quality and taste of red wine, but more than 30℃ ambient temperature will greatly reduce the effect of fungicides;
There are also commonly used chemical crosslinking agent raw materials divinylbenzene, 9 types of dangerous goods, more than 20℃ ambient temperature will make the product deterioration;
There are also commonly used water treatment agents calcium hypochlorite, 5.1 dangerous goods, greatly affected by the ambient temperature, the ambient temperature rise will make the product internal heat storage will rise sharply, and eventually will burn and explode;
There are also some self-reactive substances of class 5.2, SADT (self-accelerating reaction temperature) will affect its self-reaction speed with the ambient temperature, and it is very dangerous without temperature control. Similar to the above dangerous goods are also very much, so the international trade of such dangerous goods must rely on a complete set of cold chain transport channels to carry out.
At present, the cold chain transport of dangerous goods is becoming more and more perfect, and the transport temperature of goods can be controlled within a certain range from door to door. As a domestic professional dangerous goods freezer and freezer forwarder, Haituo supply chain to introduce the dangerous goods freezer transport process and some points of attention:
1. At present, there is only full-container service for the transport of dangerous goods by sea freezer and freezer. LCL goods are subject to different sources, weight and nature of goods, so there is no LCL service for dangerous goods freezer.
2. Dangerous goods freezer belongs to special container, freight need special application. When applying for freight, you need to provide English MSDS of the goods, requiring refrigeration temperature, temperature control range, humidity requirements, whether the vent is required to be closed or opened. When booking the space, in addition to providing the power of attorney, English MSDS, dangerous bag certificate and other information, it is also necessary to provide the above refrigeration temperature, temperature control range, humidity requirements, vent requirements, etc.
3. The refrigerator comes with a compression refrigerator, which needs to be plugged in to run. Therefore, the warehouse and trailer vehicles are required to have plug-in functions.
4. Before lifting the dangerous goods freezer, it is necessary to apply to the container manager of the shipping company for the lifting plan, confirm whether pre-refrigeration is required, and make the plan to the lifting and storage yard. After receiving the plan, if you need to apply for pre-cooling, the storage manager will adjust the temperature first. Therefore, the dangerous goods freezer can not specify the box number, we must reserve the time for the approval of the booking, and arrange the freezer packing plan before the cut-off and declaration, and get the box number as soon as possible.
5. Dangerous goods freezer, accept the door trailer and into the warehouse loading two forms of operation. The gate trailer needs to be plugged into the whole truck for refrigeration; If it is loaded into the warehouse, the empty box needs to be pre-cooled at least one day in advance, and the cold chain car and freezer transfer goods as seamless as possible, it is best to arrange the transfer and loading of goods in the refrigerated reservoir area.
6. The inner wall of the dangerous goods freezer is basically made of stainless steel, and the surface is smooth without hooks, so if the product can not fill the entire container, the reinforcement is generally adopted in the combination of reinforcement methods such as rod/airbag/strap.
7. Shanghai Port dangerous goods freezer, whether it is several types, the outer port should be entered into the dangerous warehouse, Yangshan should be installed directly. Because the dangerous goods storage area in the port area does not have a plug-in area, it cannot be cooled.
8. Dangerous goods freezer freezer, the control temperature can be displayed on the bill of lading, and the bill of lading box type shows RF (REEFER), which proves that the whole company is indeed operating in accordance with the freezer freezer.
9. Dangerous goods freezers at the port of destination are basically unloaded alongside the ship, that is, before the ship arrives, the pick-up truck will wait for the ship to dock and unload. So before picking up the goods need to let the team grasp the time of picking up the goods.
10. With the progress of science and technology, many dangerous goods freezers now have intelligent systems to record the temperature. Some dangerous goods freezers without intelligent control systems can be purchased online and put into the container for temperature control supervision.
Haitou supply chain can provide dangerous goods freezer booking, lifting, pre-refrigeration, door cold chain trailer, dangerous goods cold storage, customs declaration, dangerous goods declaration, foreign door DDU/DDP services.
