Embodiment Construction

[0026] As shown in Figure 1, the winnowing method of the present invention is, first the tobacco material is sent into the primary wind sub-chamber wind 2 with the higher wind speed of winnowing through conveying equipment 4, separates out the sundry with bigger density, this sundry Discharge from the primary miscellaneous outlet 21; then, the tobacco material after the primary air separation enters the secondary air sub-chamber 3 with a lower wind speed for winnowing, and the air separates the secondary heavy impurities, which are discharged from the secondary miscellaneous outlet 35. The tobacco material after two air separations is output from the discharge port 31 under the action of wind force.

[0027] In the actual operation process, according to the different tobacco materials to be processed, or the different conditions of the same material, the matching primary and secondary wind speeds should be properly selected and adjusted to obtain sufficient sorting accuracy. F...

Abstract

The invention provides a tobacco material winnowing method and an equipment thereof. The tobacco material enters through a transportation equipment into a primary winnowing room to choose sundry goods of larger density by the primary winnowing room having higher wind speed; the tobacco material which is wind separated by the primary winnowing enters into a secondary winnowing room having lower wind speed to choose sundry goods with less larger density; the tobacco material which is wind separated by the two winnowing processes is output via a discharge opening. The equipment implementing the method comprises two winnowing rooms connecting with each other in parallel, supplementation wind gap of each winnowing room is provided with a damper to obtain proper air quantity and air speed for winnowing. The equipment is capable of achieving winnowing the tobacco material for two times with enhanced winnowing efficiency, simple structure and convenient maintenance.

Description

technical field [0001] The invention relates to a method and equipment for sorting tobacco materials, in particular to a method and equipment for sorting tobacco materials by means of winnowing. Background technique [0002] During the production of tobacco products, tobacco materials are usually mixed with various foreign matters, which will affect the quality of finished cigarettes. Tobacco companies usually use winnowing to remove foreign matter in tobacco materials. The basic principle of winnowing is to separate the tobacco material with a relatively small suspension speed from the foreign matter with a relatively high suspension speed according to the difference in the suspension speed of the material and foreign matter. However, when the difference in the suspension speed of the material and the foreign matter is not large, the separation efficiency will decrease. In order to improve the accuracy of winnowing, multiple winnowing equipment can be connected in series ...
