1, frozen and refrigerated containers before booking must implement the specific name, the refrigerated degree, ventilation degree, three refrigerated, frozen main container booking.

2, refrigerated containers by as pay attention to itself, refrigerated cargo temperature control more difficult, and the temperature fluctuations of the goods, general refrigerated cargo has ventilation requirements, general agricultural and sideline products and fruit selection of reefer containers, general ventilation degrees will remain In 10CBM/HOUR-15CBM/HOUR, the decay in order to prevent goods.

3, General refrigerated containers generally control the temperature is less demanding, temperatures in the minus 15'C-22'C between, such cargo is generally aquatic and processing of vegetables and strawberries, taro, generally deep frozen cargo of container reflect the cooling effect is not obvious, as long as the desired temperature, generally deep-frozen goods within 24 hours will not be thawed and variable temperature, shipping companies are generally more acceptable deep-frozen goods.

4, Booking after the general shipping companies or their agents will be booking commissioned on the degree of refrigeration, ventilation and degree of notice the yard and the station freezer container pre-screening (PTI test), that is, the temperature in the state of empty containers master plate adjusted to a predetermined temperature, the plug-in refrigeration, until the empty box to the desired temperature can be. After completing the PTI inspection before suitcase loaded.

5, frozen and chilled container land the way is particularly important to note that refrigerated containers due to low temperature, the temperature change is slow. Refrigerated containers, due to temperature control in the upper and lower 0'C reflect on the outside temperature sensitive, so under normal circumstances (especially in summer) in the land process, refrigerated containers need to add a generator for the entire cooling in order to avoid large temperature difference, resulting in cargo damage . Refrigerated containers, in principle, to add a generator, the cargo is loaded at the factory Ravenna to the yard refrigeration can. (Long-haul also need to add a)

Frozen, chilled container of knowledge:

Insulated Container (Keep Constant, Temperature the Container) they are goods for transport need to be refrigerated or insulation. All walls of the box is a container made of low thermal conductivity materials, insulation and can be divided into the following three:

① refrigerated container (Reefer Container) which is based on the transport of refrigerated food products, insulated containers to maintain the set temperature. It is designed for transportation, such as fish, meat, fresh fruit, vegetables and other foods specially designed. Refrigerated containers used in international basically two types: one is called mechanical refrigerated containers with freezer container; another box there is no freezer and only insulation structure, that is located in the container side walls air intakes and vents, boxes installed in the cabin, air-conditioning supply from the ship's refrigeration equipment, this is called a clutch refrigerated containers (also known as external or folder hoop refrigerated containers).

② insulated container it is adequately insulated container structure in order to maintain the freshness of the goods for the carriage of fruit, vegetables and other goods, to prevent the temperature rise is too large. Typically used ice as refrigerant, the holding time of 72 hours.

③ ventilated container (Ventilated-Container) for the shipment of fruits, vegetables, etc. does not require freezing and respiration of the goods, with ventilation holes in the end wall and sidewall of the container, such as the vents shut down, the same as a grocery container to use.

Many shippers in the export of chilled (frozen) packing of goods, like container pre-cooling to the set temperature, this approach is unscientific, may have a negative impact on cargo and container have thus does not guarantee high-quality container refrigerated (frozen) transportation. The reason is that, before the loading of pre-cooling container, then open the door ready to load, outside temperature, high humidity air will enter the cabinet and low humidity, low temperature air convergence, which would make a large number of drops of water condensation in the container on the inner wall, these drops of water not only will drip onto the packaging of goods in order to affect the outer appearance, but will affect the operation of the container refrigeration system, which may adversely affect the quality of the goods. These condensing out of the water by the container refrigeration system evaporator to get rid of these condensing out of the water after the evaporator coil will freeze, which will make the cooling system for a short defrosting process.

On the other hand, the evaporator must also remove the following three parts heat:

Loading through the door directly into the cabinet of the heat;

2 through the cabinet wall and in through a drawer of heat;

(3) fresh produce, live goods metabolism and produce heat. Imagine, if refrigerated containers need to remove the extra heat and humidity more then the main application to cooling of the goods themselves cooling capacity will be less.

Therefore, the export of chilled (frozen) the cargo is best not to pre-cooling container, tropical and subtropical regions and summer high temperature season packing more attention to scientific refrigerated (frozen) packing of goods should be pre-cooling of goods to the set temperature, then the insulation between the goods through the cold storage and refrigerated containers channel quickly into the container. Of course, pre-cooling container temperature and cold storage at the same temperature and in cold storage and container, an insulated channel is pre-cooling before loading the container.
