Cold chain

Stacked storage. There are several means in which cold chain products can be transported, including refrigerated trucks and railcars, refrigerated cargo ships, reefers as well as by air cargo. It is a technology since it relies on physical means to ensure appropriate temperature conditions along the supply chain.

Cold chain pharmaceutical products

Generic name for a temperature controlled transport unit, which can be a van, small truck, a semi trailer or a standard ISO container. The refrigeration unit of a reefer requires an electric power source during transportation and at a container yard. The cold chain is also a public health issue since the proper transport of food products will reduce the likeliness of bacterial, microbial and fungal contamination of the shipment. This process was also seen in the late s for the movement of food from rural areas to urban consumption markets, namely dairy products. Cold-chain: the last child, the last mile Ensuring vaccines reach every child, wherever they live, is a complex process. This tend to be associated with lower operating expenses, but consumes more space. They can also be used in delivery vehicles to keep temperature constant for short periods of time, a process that can be suitable for deliveries in noise sensitive areas or for night deliveries. The greater the physical separation, the more likely freight can be damaged in one of the complex transport operations involved. This convey the advantage of manufacturing reefers next to major export areas of refrigerated cargoes fruits such as oranges and grapes. It takes time and coordination to efficiently move a shipment and every delay can have negative consequences, notably if this cargo is perishable. For instance, a refrigerated container must be steam cleaned to remove the risk of bacterial contamination and brought to the specified conditions of the shipper, namely temperature and humidity. Providing facilities for the transformation and processing of goods as well as ensuring sanitary conditions. Cold air coming out of the refrigeration unit flows through the bottom part of the reefer and as it warms up it climbs towards the ceiling to flow back to the refrigeration unit, usually 0. Consolidating and deconsolidating loads crates, boxes, pallets for distribution. Some domestic or transnational supply chains may only require one transportation mode, but many times ground shipments are only one link in a combination of transport modes.

Using yard equipment such as reachstackers to stack reefers up to three in height. The structure of global maritime shipping is thus adapting to service the reefer trade implying a shift away from specialized ports, or specialized terminals within ports, to standard container terminals.

These help ensure that a food, pharmaceutical, or vaccine is safe and effective when reaching its intended consumer. Of the non-functional units, are over 10 years of age, thus making them uneconomical to repair.

The container makes loading and unloading periods shorter and less susceptible to damage both on the container and its cargo.

It is important to underline that the refrigeration units are designed to maintain the temperature within a prefixed range, not to cool it down.

types of cold chain

Any anomaly is thus considered to be a Non Conformance and should be assigned as a trackable event. Under specific circumstances, reefers can even be used as refrigerated storage units.

Cold chain equipment

Any anomaly that occurs once a process is in a state of control may result in the process being invalidated and not in control and could potentially result in product withdraw from the market to ensure patient safety. This implies that a reefer has less volume than a regular container of the same size. Using yard equipment such as reachstackers to stack reefers up to three in height. The difficulty of this task differs depending on the nation or economic bloc and the gateway since there are variations in procedures and delays. A conventional method where reefers are placed on chassis which are moved to a parking area where each parking slot has a electric reefer plug. Specialization of agricultural functions permitting the transport of temperature sensitive food products to distant markets. Short distances can be handled with a van or a truck, while a longer trip may require an airplane or a container ship.

This training is expected to further enhance the capacity of the regions to independently run effective maintenance of their cold chain equipment. During regulatory inspections of quality systems, inspectors will frequently ask to review a list of all "open" Non Conformances" so that they can quickly assess how an organization is processing these events and ensuring they are dealt with in a timely manner.
