Provided is a formula threshing and redrying processing technology based on features of tobacco. According to the technology, the classified threshing and redrying are achieved according to the mechanical property of raw materials of the tobacco in a formula module, and the formula threshing and redrying production is achieved by additionally arranging a material flow scale and a sheet tobacco mixing cabinet between the step of sheet tobacco redrying and the step of prepressing and packaging. The technology comprises the following specific steps that 1, the mechanical property of the raw materials of the tobacco in the formula module is measured; 2, the raw materials of the tobacco in the formula module are classified; 3, the classified threshing and redrying of the raw materials of the tobacco in the formula module are achieved; 4, tobacco sheets are mixed; 5, the tobacco is packaged and put in a storage. According to the technology, the raw materials of I-class tobacco and II-class tobacco are adjusted, and the formula threshing and redrying of the tobacco of different producing areas, different grades and different years are achieved under the same threshing and redrying processing condition; meanwhile, the raw materials of the tobacco are classified according to the features of the tobacco, on the basis of ensuring the quality of the finished tobacco sheets, existing single-grade and multi-batch production is changed into two-batch formula threshing and redrying production, and the production efficiency is improved obviously.
