The whole process is - 22 ℃! Zhong Xuegao cold chain logistics originally used it

Recently, Zhong Xue, an online red ice cream, frequently appeared on the microblog hot search list. Zhong Xue Gao, who came out of the circle with high price and high appearance value, attracted young people. At the beginning of its establishment, he focused on online sales and made a lot of money in the e-commerce network market. But in recent years, the brand has gradually put down its stature and entered the offline husband and wife grocery store. Zhong Xuegao's "coming down to earth" may be related to the neck of cold chain logistics in the last kilometer of the sinking market.

"Last kilometer" is a phrase that the traditional transportation industry likes to emphasize, and in the field of cold chain logistics, every kilometer is particularly important. Compared with ordinary transportation logistics, the cold chain mainly engaged in fresh products needs to continuously ensure the freshness of goods. When ice cream is transported, the difficulty and cost rise to another level - ice cream is extremely sensitive to temperature, and the consequences of thawing are quite obvious.
The key of cold chain logistics lies in the word "cold". Refrigeration is the most important step in the whole transportation link. In order to ensure that the ice cream will not be melted during transportation, it is necessary to ensure that the temperature and humidity in the cargo compartment are appropriate. The temperature setting in the specific transportation process should also be determined according to the specific conditions of transportation, and the refrigeration operation should be carried out in strict accordance with the requirements to ensure the quality of goods, To prevent unnecessary losses.

Zhong Xuegao claimed that the whole process is - 22 ° cold chain, and each cold chain car is additionally equipped with temperature sensing instruments to ensure that the temperature can be mastered at any time no matter how far the transportation distance is.

With the development of science and technology, it is more and more common to assemble wireless temperature and humidity sensors in cold chain vehicles and combined with temperature and humidity monitoring system to monitor the temperature and humidity during transportation. Compared with the traditional temperature and humidity measuring instrument, the intelligent digital temperature and humidity sensor does not need manual operation. It can preset the temperature and humidity range, automatically trigger the refrigerator and ventilation system, and can perfectly control the temperature and humidity within the required range.

At present, there are few domestic enterprises that can produce high-quality temperature and humidity sensors, and the product quality can be comparable to the international front line is rare. The aht21 digital output temperature and humidity sensor developed and manufactured by Guangzhou Aosong Electronics Co., Ltd., a domestic first-class sensor supplier, adopts brand-new chip design and new humidity sensing materials, which can maintain good stability even in the extremely harsh environment of high temperature and humidity or low temperature and low humidity for a long time, Ideal for OEM applications that require reliable and accurate measurements.

Aht21 temperature and humidity sensor adopts double row flat pinless SMD package suitable for reflow soldering. The size is only 3 x 3 x0.8mm. It outputs calibrated digital signal in standard I2C format. The temperature sensing element of the sensor can effectively measure gas, liquid or solid. It has the advantages of high precision, fast response, strong anti-interference ability and high cost performance. It can design and customize modular products for traffic applications, which can not only meet the specific application needs of different customers, but also be easily compatible with most existing applications.
But the above is the B2B cold chain logistics transportation mode. If it is for B2C which needs independent refrigerated packaging, it can only adopt the remote delivery method of dense foam box + dry ice, and the distribution cost is very high. This may be one of the fundamental reasons for Zhong Xue to sink into the physical market.
