Embodiment Construction

[0013] according to figure 1 figure 2 , After the tobacco leaves undergo a series of processing such as vacuum rehydration, primary leaf moistening, sand screening, and secondary moistening, the tobacco leaf materials come to the wind flotation equipment. The tobacco leaves first pass through the flat feeding belt 1a, then reach the lifting belt 2a, and then reach the feeding conveyor belt 4a. Through the action of the uniform roller 3a, the tobacco leaves are evenly distributed on the feeding conveyor belt 4a raised to a certain height. The throwing roller 5a at the end of the conveyor belt 4a throws the tobacco leaves evenly into the winnowing bin 7a. During the free fall process of the tobacco leaves, the wind outlet 6a blows out suitable wind to make the sessile tobacco sheets in the tobacco leaves float and blow into the sessile tobacco leaves. The tobacco sheet discharge port 10a is collected by the feeder 11a and sent to the multi-layer vibrating sieve. The multi-laye...

Abstract

The invention discloses a threshing and redrying processing method and relates to threshing and redrying processing, and belongs to the technical field of tobacco leaf threshing and redrying processing in tobacco industry. The method includes the following steps: after conducting secondary leaf moistening, performing gravity winnowing on all the mixed materials, such that tobacco leaves that contain stalks fall to the bottom part and continue to undergo threshing and wind separation; blowing tobacco leaves without stalks and smashed tobacco leaves to an outlet in the upper part for performing screening, the tobacco leaves without stalks obtained after the screening directly entering the step of redrying tobacco leaves, while the smashed tobacco leaves entering a smashed tobacco leaves production line. According to the invention, the method can greatly reduce smashing rate of tobacco leaves after undergoing threshing and redrying, and increases total weight of the tobacco.

Description

technical field [0001] The invention relates to a threshing and redrying process, which belongs to the technical field of tobacco leaf threshing and redrying processing in the tobacco industry. Background technique [0002] Threshing and redrying is a technology for processing raw tobacco, and it is a processing process for transforming tobacco leaves, an agricultural product, into industrial raw materials. Through the processing of threshing and redrying, the damage rate of tobacco leaves is reduced, so as to provide standardized raw materials to tobacco factories to ensure the quality of shredded tobacco. Before threshing and re-baking, the tobacco leaves should be pretreated firstly, that is, the bundled tobacco leaves should be untied and spread out, and humidified and humidified to meet the requirements of the threshing process. However, in this process, a part of the stalkless tobacco sheet is often produced, and theoretically, this part of the tobacco sheet does not ...
