The influence of science and technology on cognitive change has a long history, which lead to forming philosophy of science and philosophy of technology respectively. The development of grain storage technology in China has gone through three stages: the initial exploration before the reform and opening up, the construction of intellingence in the past 10 years modern granaries in 30 years after the reform and opening up, and the creation of digital. The scientific and technological progress of grain storage in China has been witnessed by all, including building a modern granary with "four in one" new grain storage technology, to forming the world's largest grain and food networking with information technology, original multi-field coupling and bio-field theory, and realizing the dynamic supervision of grain reserves with grain cloud image scanning technology. In the new era, the political and economic situations have not changed significantly in the past century, and the new requirements of China's second centenary goal for food security and the impact of the fourth industrial revolution have made the trend of food science and technology becoming more and more intelligent. Based on the accumulation of scientific and technological achievements in grain storage practice for more than 40 years in China, combined with the team's research on multi-field coupling and bio-field theory of grain storage, dynamic supervision of cloud image of grain reserves, 5T information management of natural block chain for grain storage, and intelligent EAT window measurement and control methods for grain drying, this paper attempted to take the basic idea of "one divides into two, two divides into three, and three generates changes" on the basis of deconstructing the micro and macro ternary microstructure of grain storage system. Taking the joint driving of mechanism and data as the intelligent strategy, the granary philosophy is introduced to improve the recognition of existing scientific and technological achievements. The granary philosophy also guided the exploration of grain storage technology in the new era, and provided support for building a high-quality intelligent food system. The granary philosophy is a deep reflection on the practical situation of grain storage, and has certain universality, which originates from grain storage practice, but is not limited to grain storage practice
