Evolution Pattern of Paddy Temperature Field in Quasi-low Temperature Storage in Flat Stores
This study investigated the spatiotemporal evolution of the temperature field of paddy in quasi-low-temperature storage in flat stores using experimental research and numerical simulation.he evolution pattern of the paddy temperature field was derived from a 14-month grain temperature experiment in quasi-low-temperature storage.A numerical model of the temperature field in quasi-low-temperature storage was developed and validated against experimental results.Finally,the temperature profile of paddy over 26 months was predicted by the proposed numerical model.The conclusion can be expressed as follows:During the 14-month experimental period,the overall average temperature of paddy remained below 17℃,with a maximum of 15.57℃and a minimum of 11.32℃.The 26-month quasi-low temperature storage period in the storehouse was simulated by using the above model.The simulation results showed that the overall average temperature of paddy gradually increased but remained below 17℃.The monthly average maximum grain temperature occurred in September each year,with values of 14.85℃and 15.34℃in the first and second years,respectively.Similarly,the highest surface grain temperatures,15.3℃and 15.8℃,were also recorded in September.The evolutionary rule of the paddy temperature field,as elucidated in this paper,offers theoretical support for the quasi-low temperature storage of paddy in storehouses.
