Due to the application of the thin pressing and thin cutting process, the degree of unevenness of the cut stem is increased. The stem shreds with too small thickness are expanded and dried to become light and thin sheet-shaped stem shreds, and the dried light and thin sheet-shaped stem shreds are mostly white in color, transparent and transparent, and have small density and many sheet-shaped. In the subsequent processing process, the light and thin flaky cut stems are characterized by easy breakage, low processing resistance and the like, and particularly in the blending link with cut leaves, the blending uniformity of the cut stems is reduced.
