Problems solved by technology

The mixture of shredded tobacco and stem sticks removed from the cigarette rolling machine has undergone multiple winnowing during the whole process of shredded tobacco. This method does not change the physical state of the mixture of shredded tobacco and stem sticks after cooling the cut tobacco. It is difficult to achieve the separation of cut tobacco and stem sticks. Separation, the two combing rollers of the combing equipment rotate inward at the same time, which will not only cause the shredded tobacco to be broken, but also squeeze the shredded tobacco to form new shredded tobacco agglomerates, and finally it is difficult to separate the shredded tobacco stem sticks. The actual use effect also proves that got this

Embodiment 1

[0034] Such as figure 1 , 2 As shown, the shredded tobacco winnowing equipment provided by the present invention comprises a feed air lock 1, a feed pipe 2, an air inlet pipe 3, a winnowing chamber 4, and a tangential feeder 8; the feed pipe 2 and the feed air lock 1 connection; the air selection chamber is connected with the feed pipe 2 and the air inlet pipe 3 respectively; the bottom end of the air selection chamber 4 is connected with the stem-out air lock 7, and the top of the air selection chamber is connected with the tangential feeder 8; The chamber 4 is provided with material equalizing rollers 5 and air equalizing plates 6. The air equalizing plates are vertically arranged and evenly distributed in the winnowing room. The general distance is about 50-100 mm. The lower end of the air equalizing plates faces the air outlet of the air inlet pipe. Tilting, facing the direction of the wind, the mouth of the air equalizing plate is vertically upward, the main function of ...

Embodiment 2

[0041] The structure of this embodiment is arranged as image 3 As shown, the first-level winnowing equipment I and the second-level winnowing equipment II all adopt the shredded tobacco winnowing equipment in Embodiment 1, and the first-level winnowing equipment I and the second-level winnowing equipment II are connected by connecting pipe III, that is , the discharge port of the tangential feeder of the primary wind separation equipment I is connected to the feed air lock of the secondary wind separation equipment II through the connecting pipe III. In this scheme, the wind speed selected for the winnowing wind in the winnowing room of the first-level winnowing equipment I is higher than the average level, about 3-4.5m / s, so as to ensure the removal of stems in the process of winnowing. The silk content is small, and the purity of cut tobacco after the first winnowing is about 60-80%. After the second winnowing equipment II winnows again, the object of the second winnowing i...

Embodiment 3

[0043] The structure of this embodiment is arranged as Figure 4 As shown, the primary winnowing equipment I adopts the shredded tobacco winnowing equipment in Embodiment 1, IV is an improved secondary winnowing machine, and the connecting pipe V is used to connect between I and IV, that is, the primary winnowing equipment I The stem-out air lock is connected to the feed port of the secondary winnowing machine IV through the connecting pipe V. The outlet of the secondary winnowing machine sends the shredded tobacco to the belt conveyor Ⅵ through the tangential feeder, and merges with the shredded tobacco picked out by the first winnowing equipment Ⅰ. In this scheme, the wind speed selected for the air selection in the air selection room of the first-level air selection equipment I is lower than the average level, about 2-3.5m / s, so that the shredded tobacco selected by air can be guaranteed in the process of air selection. The purity rate is greater than 90%, and the shredded...

Abstract

The invention provides a method and device for efficiently winnowing tobacco shreds. Tobacco materials are fed into a winnowing chamber through conveying air, and the tobacco materials are loosened by a material equalization roll in the winnowing chamber and evenly distributed in the winnowing chamber; winnowing air is fed into the winnowing chamber, suspension winnowing is carried out on the tobacco materials in the winnowing chamber, and sundries are separated out; and meanwhile, the caked tobacco materials are suspended on air equalization plates in the winnowing chamber and are repeatedly jolted to be loosened under the action of upward blown winnowing air and gravity. A multilevel winnowing scheme is further designed, the amount of the materials subjected to secondary winnowing is greatly reduced, and therefore the purity of the tobacco shreds is improved, and energy consumption for winnowing is effectively reduced. According to the method and device, the winnowing efficiency is high, the purity of the tobacco shreds is high, and crushing is greatly reduced.

Description

technical field [0001] The invention relates to a high-efficiency shredded tobacco winnowing method and shredded tobacco winnowing equipment. Background technique [0002] The stems in the shredded tobacco need to be removed during the processing of the shredded tobacco, so as to improve the efficiency and the quality of the cigarettes in the shredded tobacco rolling process. The shredded thread is generally air-selected to remove the stems after the shredded tobacco is dried, and the shredded tobacco-containing stems removed during the crimping and wrapping process are also extracted for reuse. Existing technology of removing stems from shredded tobacco mainly contains the following types. [0003] Tobacco shredded stems removed during crimping and wrapping are extracted and reused. HT is generally used to increase temperature and humidify the mixture of shredded tobacco stems to loosen the shredded tobacco and increase the density difference of shredded tobacco stems. Af...
