Cold chain distribution system and method for distributing or selling products and low-temperature milk by using cold chain distribution system

Abstract

The invention discloses a cold chain distribution system and a method for distributing or selling products and low-temperature milk by using the cold chain distribution system. The cold chain distribution system comprises a discharging refrigerated storage, a transport vehicle with a refrigerated carriage, a plurality of storage boxes, a self-service refrigerated cabinet and a cloud server. A temperature sensing positioner is arranged in each storage box; the temperature sensing positioner is connected with the cloud server through the communication module; the self-service refrigerated cabinet is installed on a distribution terminal. The self-service refrigerated cabinet comprises a box body, a plurality of unit grids arranged in the box body, a refrigeration module connected with each unit grid, a control circuit board and an Internet of Things module, wherein the Internet of Things module is connected with the control circuit board and the cloud server, each unit grid is provided with a unit lock connected with the control circuit board, and an identity recognition module is arranged on a box door of the box body. The refrigeration temperature can be monitored in real time, it is ensured that a product is always in a specified low-temperature environment, product deterioration is avoided, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of product preservation, in particular to a cold chain distribution system and a method for distributing or selling products and low-temperature milk using the cold chain system. Background technique [0002] There are two main types of milk on the market: one is pure milk (also known as "normal temperature milk"), which is used for long-term storage and long-distance transportation, at the expense of nutrition, and is treated with ultra-high temperature. The shelf life is more than half a year. , can be restored with milk powder. [0003] The other is pasteurized fresh milk. In order to preserve the natural nutrition of milk, the pasteurized fresh milk processed by low-temperature sterilization process has the characteristics of "pure natural, original flavor and maintaining activity". Pasteurized fresh milk uses pasteurization to heat the milk to 70-85°C, keep it for 1-15 minutes, and then cool it rapidly...

AI Technical Summary

Problems solved by technology

[0005] At present, an important reason hindering the development of pasteurized fresh milk is in the distribution stage of pasteurized fresh milk. The shelf life of pasteurized products is short, and a cold chain system is required during transportation.

However, there are still many imperfections in the current cold chain system in our country, so that for consumers, pasteurized milk also has shortcomings such as not being able to drink anytime and anywhere and not being easy to store.

Especially in the final delivery link, the traditional method is that the delivery personnel put the pasteurized fresh milk into the ordinary milk box set up downstairs by the subscribers. Since the delivery personnel target more subscribers and the delivery time is longer, the pasteurized fresh milk will It may have exceeded 6°C or even higher before the milk box, and the milk box does not have a refrigeration function. When the subscriber takes the pre-pasteurized fresh milk from the milk box, it has been placed at room temperature for 4 to 5 hours or even longer, especially in summer. It increases the possibility of outbreaks of product safety issues, and at the same time reduces subscribers' confidence in pasteurized fresh milk; at the same time, this traditional delivery method also has the following problems, the delivery staff is inefficient and the delivery time is relatively early, generally The delivery starts in the early hours of the morning. Subscribers must pick up the pasteurized fresh milk on time and on time and cannot cancel the delivery for today or a certain period of time due to temporary reasons. There is a lack of timely communication between delivery personnel and subscribers, and subscribers in the same community or area are scattered. Personnel need to deliver milk from door to door, the workload is heavy and time-consuming

In short, the existing delivery work at this stage is very inflexible, which not only reduces the subscriber experience, but also increases delivery costs and risks
