The invention discloses a re-drying method for improving quality of re-dried tobacco laminas. Different drying curves and processing parameters are set to re-dry tobacco materials respectively according to characteristics of the tobacco materials on the upper portion, the middle portion and the lower portion and the moisture and the temperature of tobacco laminas entering a drying machine. According to the re-drying method, change trends of the drying curves are smooth, temperatures of zones of a drying section are lower than those of traditional machining, the mesh belt speed is low, and 'low-temperature slow-drying' can be achieved. Compared with a traditional machining method, the re-drying method has the advantages that the temperatures of zones of the drying section are low, and the mesh belt speed is low, so that leaves of re-dried tobacco laminas are bright and uniform in color and luster, elastic and loose in tissue structure; sensory quality indexes such as the aroma amount, dedicate degree, dopant g
