The role of temperature and humidity sensor in cold chain transportation

What is cold chain logistics?

Cold chain logistics refers to the fact that temperature-sensitive products are always in a prescribed low temperature environment in the process of storage, transportation and sales. Ensure food quality and reduce food losses. It was established with the progress of science and technology and the development of refrigeration technology. It is a low temperature logistics process by means of refrigeration technology and refrigeration technology. For temperature monitoring, we can use temperature and humidity sensors.

The composition of cold chain logistics

Cold storage: One of the core components of cold chain logistics is the “cold storage”, which includes the constant temperature and humidity cold storage with precise requirements on the humidity and temperature of the stored items and the “air-conditioned cold storage”. It has the effect of air conditioning preservation.

Cold chain transport: at a certain temperature, the sorting, picking and packaging of fresh agricultural products can be achieved by using the required transport machinery and appliances.

Cold chain loading and unloading: This is a very important and difficult step. When refrigerating or freezing goods, the unloading vehicle and unloading warehouse should be sealed to ensure that the temperature rise of goods during unloading is controlled within the permissible range. When the unloading operation is interrupted, the doors of the transport equipment should be closed immediately to maintain the normal operation of the cooling system.

Cold chain transport: This is an important link of cold chain logistics. The cost of cold chain transportation is relatively high, which includes more complex refrigeration technology and monitoring technology, such as temperature and humidity sensors, refrigerators, temperature recorders, etc. Cold chain transportation management contains more risks and uncertainties.

Products suitable for cold chain logistics

Primary agricultural products
Vegetables, fruits, meat, eggs, aquatic products, flower products.

Processed foods,
Frozen food, poultry meat, meat, aquatic products and other packaged deli, ice cream and dairy products, chocolate, fast food raw materials.

Medicine, therefore, is higher than the general room temperature logistics system requirements, more complex, construction investment is also much larger, is a huge system engineering.

Temperature and humidity recorder

The working method of temperature and humidity recorder is very simple. The collected temperature and humidity are periodically written into the recorder’s memory. After transportation, all point-to-point supply chain temperature data are read at one time to generate a static temperature change map. To monitor the temperature change of the supply chain. Take the drugs that need temperature management in hospital medicine cabinet supervision as an example. The temperature and humidity recorder can be placed in the medicine cabinet, and the data can be downloaded regularly to check the temperature change. When the temperature exceeds the set temperature, the alarm is timely to form the early warning function.

For example, in the cold chain supply chain, the consignee will give the temperature recorder to the shipper in advance, and the consignor will put the temperature recorder into the package when delivering the goods. When the goods arrive, the consignee reads the data through computer software, which automatically generates static maps of temperature changes throughout the supply chain. If THE temperature exceeds the preset specified temperature, the temperature recorder will make the corresponding record, and read by the software, can be queried by time. The temperature static graph has time on the horizontal axis and temperature on the vertical axis, so that you can know exactly when the temperature has changed, which is convenient for information tracing.

Temperature and humidity sensor

The temperature and humidity sensor adopts a high degree of protection enclosure, and the degree of protection is IP65. It can be used in outdoor or high dust occasions. High sensitivity, accurate measurement, no fear of condensation, strong anti-interference, stable performance.Temperature and humidity sensors can be used for temperature and humidity detection in harsh environments such as industrial plants, traffic tunnels, energy, and electricity, as well as temperature and humidity detection in computer rooms and laboratories such as fruit trees, gardens, agricultural pastures, agricultural greenhouses, and flower breeding.JXCT is an equipment manufacturer with many years of experience, direct sales, reliable quality assurance.
