Evaluation method for flexible in-situ winnowing effect of cut tobacco

The invention discloses a method for evaluating the flexible in-situ winnowing effect of cut tobacco, which comprises the following steps of: determining evaluation indexes for evaluating the flexible in-situ winnowing effect of the cut tobacco, including a moisture loss rate, a reduction amount of a whole cut tobacco rate, a cut tobacco content rate of rejected stem slivers and a stem sliver rejecting rate; determining an evaluation standard of each evaluation index; calculating each evaluation index; and according to the calculation result of each evaluation index, the local winnowing effect is evaluated, if the calculation result of each evaluation index falls into the corresponding evaluation standard range, the evaluation result is qualified, and if the calculation result of at least one evaluation index does not fall into the corresponding evaluation standard range, the evaluation result is unqualified. According to the evaluation method for the tobacco shred flexible in-situ winnowing effect, a scienti
