Apparatus and method improving tobacco leaf yield after first time threshing

Abstract

The invention relates to the technical field of tobacco leaf indicator improvement after threshing and air separation and concretely relates to an apparatus and a method improving tobacco leaf yield after first time threshing. The method comprises steps of (1) improving air separation efficiency of an air separator and increasing tobacco leaf amounts separated by each grade of air separator, (2) sieving out super-large tobacco leaves separated by each air separation and collecting the super-large tobacco leaves via a large tobacco leaf collecting belt, (3) threshing and eliminates eliminating stalks of the collected large tobacco leaves collected in the (2) step, and (4) normally air-separating material after threshed and separating the tobacco leaves and tobacco stalks. Air-selected tobacco leaf amount can be increased via improvement of the air separation efficiency of the air separator; and super-large tobacco leaves containing stalks exceeding standards are secondary-threshed and air-separated, so the proportion of tobacco containing the stalks is controlled within a standard range at last.

Description

Technical field [0001] The invention belongs to the technical field of improving blade indexes after beating and air separation, and specifically relates to a device and method for improving the leaf yield rate after one beating. Background technique [0002] The yield rate is the ratio of the amount of leaves separated by air separation after threshing to the total amount of tobacco leaves. The higher the yield rate, the smaller the loss of tobacco leaves in the threshing production line, and the greater the amount of processed tobacco products. It is directly related to the production profit of the re-bake factory, so the film yield is one of the production indicators that manufacturers pay most attention to. The leaf yield rate after one dozen is the ratio of the amount of leaves separated after the first stage of defoliation to the total blade amount. The amount of pieces after one dozen generally accounts for more than 60% of the total amount. The flake output rate aft...

AI Technical Summary

Problems solved by technology

The traditional method of processing technology to increase the rate of sheet production after a dozen is to increase the efficiency of leaf threshing after a dozen and the efficiency of air separation after a dozen. The crushing of large blades will increase the loss of blades. If the overall wind distribution efficiency after a dozen is under the existing technology and meets the requirements of the defoliation index, it will be difficult to have a greater improvement.
