The invention relates to a threshing redrying flavoring and perfuming technology. The threshing redrying flavoring and perfuming technology comprises the steps that 1, threshed strips are fed into a roller feeding machine, the roller feeding machine is started, flavored feed liquid is evenly sprayed to the rolling strips in the roller feeding machine, and the strips coated with the flavored feed liquid are stored in a storage cabinet; 2, after the strips absorb the flavored feed liquid completely, the strips are redried; 3, the redried strips are fed into the roller feeding machine, the roller feeding machine is started, perfumed feed liquid is evenly sprayed to the rolling strips in the roller feeding machine, and then the strips coated with the feed liquid are pre-pressed and packaged. According to the threshing redrying flavoring and perfuming technology, as for tobacco leaves, after stems and the leaves are separated, even flavoring is conducted before redrying, even perfuming is conducted after redrying and before pre-pressing and packaging, the technology requirement for flavoring and perfuming of the tobacco leaves is met under the condition that fewest devices are arranged, the technological process is the shortest, and feed liquid consumption is the lowest, and an efficient path is provided for reducing production cost of enterprises, improving production efficiency of the enterprises and improving internal quality of the tobacco leaves.
