Abstract: 90% of China's soybeans are imported. Imported soybeans are transported by sea, and since the transportation season is hot and rainy, beans are stocked in a humid environment for a long time. In addition, due to the transfer of moisture and heat, moisture migration, and condensation caused by the alternation of seasons during the storage, local moisture and temperature rise. In order to deal with the heat in time and reduce the economic loss of imported soybean during storage, soybeans with 20% moisture content and different qualities were embedded in soybeans with safe water content stored in a simulated warehouse with the arrangement of 9 cables. The temperature change was recorded every day to simulate the heating phenomenon caused by high moisture content in the transportation and storage of soybean, as well as the heating and heat transfer law of soybean. With the data analysis and application of Origin, the heating trend and heating range of soybean were obtained. The results showed that:even if the mass was small, high moisture content would cause heat in the soybeans, so it is very important to control the warehousing of soybeans with high moisture content. The middle layer of high moisture soybeans was heated first, then the heat will quickly move upward, causing the temperature of the upper layer of the grain pile to continue to rise and exceed the middle and lower layer. The higher the weight of high moisture soybeans, the faster the heating of upper and lower layers, the shorter the time it takes for the hot spot to appear, and the wider the area of heating diffusion. Grain heaps with high moisture content of 120 kg, 60 kg, 30 kg and 15 kg began to heat after 1 d, 1 d, 2 d and 3 d, respectively. The upper layer of high moisture soybeans (c3) increased at the speed of 2.26℃/d, 1.57℃/d, 1.47℃/d and 0.49℃/d, respectively. The highest temperatures could reach at 52.1℃, 43.2℃, 41.4℃ and 29.1℃, respectively. After the center of the grain pile heated, the heat gradually spread to the surrounding area, and the speed of spreading to the upper layer was faster than that around the grain pile, and the affected area of the upper layer was larger than that around the wet grain. The temperature cable should be set in the warehouse. It is suggested to increase the temperature measuring points in the vertical direction. The distance between the temperature measuring points should be small, and the temperature of soybeans should be monitored in real time. In case of heating, it should be handled in time.
