Cold chain logistics
Refrigerators for Cold Chain Logistics
Cold chain transport is the temperature-controlled movement of climate-sensitive goods from one place to another. A complete cold chain is a series of uninterrupted cold storage production, storage and distribution activities, together with related equipment and logistics, to maintain product quality by maintaining a certain low temperature range. It is used for the preservation of fresh agricultural products, seafood, frozen food, photographic film, chemicals and medicines to extend and ensure the shelf life of the products. Such products are sometimes referred to as cold chain goods during transportation and temporary storage.
However, due to the special requirements of cold chain logistics, the core of cold chain logistics is not only about “cold”, but “keeping the temperature at a constant level”-different products require different storage temperatures: such as quick-frozen food, frozen meat, ice cream, etc., require frozen transportation (-30℃～-18℃). Fruits, vegetables, beverages, fresh milk products, etc. need to be transported under refrigeration (freezing point ~ 10°C).
Its capacity for precise temperature control and monitoring, alert systems, and secure insulation must be considered.
Cold chain transpotation
The cold chain involves the transportation of temperature-sensitive products along a supply chain through thermal and refrigerated packaging methods and the logistical planning to protect the integrity of these shipments. There are several means in which cold chain products can be transported, including refrigerated trucks and railcars, refrigerated cargo ships, reefers, and air cargo.
Cold room storage
The cold storage facility is the most commonly used in cold chain logistics. It can range from a single temperature-controlled room servicing a single user and function to a large dedicated distribution center servicing multiple users and functions. There are also punctual examples, such as converting mines into cold storage facilities.
Regional storage facility
An unbroken cold chain is an uninterrupted sequence of refrigerated production, storage and distribution activities, along with associated equipment and logistics, which maintain a desired low-temperature interval to keep the safety and quality of perishable or sensitive products, such as foods and medicines. In other words.
The cold chain is thus a science, a technology, and a process. It is a science since it requires an understanding of the chemical and biological processes linked with perishability. It is a technology since it relies on physical means to ensure appropriate temperature conditions along the supply chain. It is a process since a series of tasks must be performed to prepare, store, transport, and monitor temperature-sensitive products. The main elements of a cold chain involve: Cold systems, Cold storage, Cold transport, Cold processing and distribution.
