This paper aims to analyze the constitution of the heating load of bulk curing barn and the heat and mass transfer process for the whole bulk curing barn and set up the energy consumption model to explore the load distribution of bulk curing barn. The hourly load is calculated in the process of tobacco curing of Yunyan 97 as an illustration. The results show that the load distribution is mainly affected by the dehydration rate of tobacco, which is similar to the distribution of humidity load; the largest heat load appears in the later period of the color fixing stage; the envelope heating load increases with the growth of time, whose amount is 15% of the amount of the heating load of bulk curing barn.
