At present, a tobacco leaf threshing and air separating operation mode is adopted in a redrying plant at the tobacco leaf crushing stage, and tobacco stems are separated through an air separating machine after tobacco leaves are crushed by a threshing machine. In order to reduce the breakage rate, the technological parameters of quick and light beating are generally adopted, so that the size distribution of the smashed tobacco flakes is generally larger, the proportion of the smashed tobacco flakes as fragments with bad sizes is qualified, the proportion of the smashed tobacco flakes as oversized fragments with bad sizes is overproof, the content of medium fragments in qualified products is too low, and the content of large fragments in qualified products is too high. In order to change the situation, secondary threshing is carried out by separating a part of large pieces and oversized pieces from the threshed tobacco leaves. Therefore, under the condition of not greatly improving the fragment rate, the large fragment rate and the ultra-large fragment rate are effectively reduced, and the medium fragment rate is improved.
The main equipment adopted by the redrying industry for separating tobacco flakes according to size is a vibrating sieve which is mainly used for separating tobacco leaf powder.
