The invention relates to a method for drying black sesame seeds. Through a lot of research, the drying heating process provided by the invention is divided into two steps, and an optimal drying process is obtained. The method on the one hand ensures the nutrition of black sesame, and on the other hand can greatly reduce the energy consumption during the drying process. The experimental results show that the power consumption for baking 500g of black sesame seeds is reduced by 5%-15% as compared to the original drying process. The black sesame seeds prepared by the drying method of the invention are especially suitable for the preparation of donkey-hide gelatin cake.
