The invention discloses a method for improving the leaf size uniformity after
threshing. Through combination of suspension
winnowing and air suction pneumatic separation, the
winnowing frequency of anair separator is improved, and the amount of leaves for
winnowing is increased, super-large tobacco stems are separated out separately and tobacco stem separation is performed, After separation, leaves are subjected to secondary winnowing
threshing, the tobacco stems are separately moistened and
cut into shreds, generation of non-
smoke substances during
tobacco leaf processing is controlled, therefined requirements of cigarette enterprises for the purity of tobacco laminas, the
processing flow is improved, and the production cost is reduced. The leaves are subjected to classification
threshing, the tobacco breaking rate is reduced, the middle-size leave rate is improved, the uniformity of the tobacco leaves is controlled, and subsequent
processing is facilitated. The provided method forimproving the leaf size uniformity after threshing has a remarkable effect, effectively improves the leaf uniformity and the threshing efficiency, improves the quality of finished cigarette products and is worth popularizing.
