Embodiment 1

[0018] figure 1 Among them, it adopts a segmented helical one-stage co-current and two-stage counter-current extraction method including three-stage extraction and two dehydration processes. The specific process is:

[0019] It adopts three series-connected spiral extractors, and the first-stage spiral extractor is completed by the first-stage spiral extractor. The first-stage spiral extractor receives fresh solvent and fresh tobacco stems, and after extracting chloride ions, the obtained tobacco stems have a weight of 1.4 -1.6 times the primary extract with a chloride ion content of about 5-7g / L, the primary extract is treated with sewage and then discharged;

[0020] The tobacco stems obtained after the first-stage extraction are sent to the second-stage spiral extractor for the second-stage extraction. During the second-stage extraction, the secondary dehydration extract obtained from the second dehydration is used for extraction; The second-stage extracts are all sent to ...

Embodiment 2

[0022] figure 2 Among them, it adopts the one-stage downstream and two-stage countercurrent extraction method of the tank group, and the specific process is as follows:

[0023] The fresh solvent and fresh tobacco stems are sent to the first extraction tank for the first-stage extraction to obtain a primary extract with a weight of 1.4-1.6 times that of the tobacco stems and a chloride ion content of about 5-7g / L. After the sewage is treated and discharged, the first-stage extraction of the first extraction tank is the first-stage downstream;

[0024] The tobacco stems after the first-level extraction are sent to the second extraction tank in turn for the second-level extraction, and the third extraction tank for the third-level extraction; the second-level extraction obtained after the second-level extraction is all sent to the extraction liquid storage tank sent to the concentration section; at the same time, the second extraction tank also receives the extract from the ex...

Abstract

The invention discloses a method for reducing the content of chloride ions in paper-making method sheet tobacco. The method has the advantages of fully utilizing active components in the tobacco obtained after extraction solution is condensed, effectively saving resources, reducing the emission of pollutants, realizing the paper-making method sheet tobacco product to restore the unique property of the tobacco to the maximum extent, solving the problem existing in the production of the prior paper-making method sheet tobacco that the content of chloride ions in the product exceeds the standard, and controlling the content of chloride ions to below 0.8 percent. The method comprises the following steps: in the production of the paper-making method sheet tobacco, utilizing a solvent to complete the multi-stage extraction of the tobacco stalks, and discharging the partial extraction solution obtained by the first-stage extraction after sewage treatment; fully condensing extraction solutionobtained by the second-stage extraction; and after the first dewatering, the third-stage extraction and the second dewatering, or the third-stage extraction and twice dewatering, performing solid-liquid separation, using the extraction solution obtained by the solid-liquid separation for the second-stage extraction of the tobacco stalks, and sending the tobacco stalks into the pulping segment.

Description

technical field [0001] The invention relates to a method for reducing the chloride ion content of reconstituted tobacco leaves by papermaking. Background technique [0002] At present, the tobacco stem extract of reconstituted tobacco leaves produced by the domestic papermaking method is not fully utilized, resulting in waste and environmental pollution; if all the tobacco stem extract is utilized, the chloride ion content of the product will exceed the standard. In the raw materials of reconstituted tobacco leaves by papermaking method, the chloride ion content of tobacco stems is 2-4 times that of tobacco dust. In order to effectively utilize tobacco stem raw materials and reduce the amount of extra fiber in the production of reconstituted tobacco leaves by papermaking method, the reasonable ratio of tobacco stems and tobacco dust is 1:1 or 6:4, if all the extract concentrate of tobacco stems is used, the chloride ion content of the produced reconstituted tobacco leaves is...
