Intelligent ventilation technology for grain storage can realize intelligent analysis and judgment of storage conditions, it can achieve full automatic monitoring in ventilation operation as well as has many advantages such as high efficiency, energy saving and labor saving. The application of intelligent ventilation technology in grain safe storage was reviewed, including in ventilation for decreasing temperature, decreasing humidity and removing accumulated heat and other aspects. The prospect of constructing the digital grain depot was also expected, which would provide references for the broader application of intelligent ventilation technology in the construction of digital granaries.
