Embodiment 1

[0019] A process for purifying reconstituted tobacco leaf extract, the method steps are as follows:

[0020] (1) After the wood pulp board is measured and weighed, use a hydraulic pulper to obtain the clear water slurry after the wood pulp board is disentangled and processed with clear water, and send it into the first slurry storage tank to adjust the clear water slurry mass concentration to 0.3%-2%;

[0021] (2) After the wood pulp board is weighed, use a hydraulic pulper to decompose the wood pulp board with the tobacco raw material extract to obtain the extract slurry, and send it into the second pulp storage tank to adjust the extract slurry Material mass concentration to 0.3%-2%;

[0022] (3) The clear water slurry prepared in step (1) is delivered to the plate-type airtight blade filter with a slurry pump, and a filter cushion layer is formed on the surface of the filter screen of the filter, and the filtrate is sent back to the clear water tank. After the filter cush...

Embodiment 2

[0026] A process for purifying reconstituted tobacco leaf extract, the method steps are as follows:

[0027] (1) After measuring and weighing the wood pulp board, use a hydraulic pulper to decompose the wood pulp board with clean water to obtain a clean water slurry and send it into the first slurry storage tank, adjust the mass concentration of the clean water slurry to 0.3 %-2%;

[0028] (2) The clear water slurry prepared in step (1) is transported to the plate-type airtight blade filter with a slurry pump, and a filter cushion layer is formed on the surface of the filter screen of the filter, and the filtrate is sent back to the clear water tank. After the filter cushion layer has a thickness required by the process and meets the filtration accuracy requirements, stop the slurry supply and drain the remaining slurry in the filter and send it back to the first slurry storage tank;

[0029] (3) Transport the extract with a slurry pump to the plate-type airtight leaf filter ...

Embodiment 3

[0032] A process for purifying reconstituted tobacco leaf extract, the method steps are as follows:

[0033] (1) After weighing the wood pulp board, use a hydraulic pulper to decompose the wood pulp board with the tobacco raw material extraction liquid to obtain the extract liquid slurry, send it into the second pulp storage tank and adjust the extract liquid slurry Mass concentration to 0.3%-2%;

[0034] (2) The extract liquid slurry prepared in step (1) is delivered to the plate-type airtight blade filter with a slurry pump, and a filter cushion layer is formed on the surface of the filter screen of the filter, and the filtrate is returned to the extract liquid storage tank. After forming a filter cushion with a thickness required by the process on the net and meeting the requirements of filtration accuracy, stop the slurry supply and drain the remaining slurry in the filter and send it back to the second slurry storage tank;

[0035] (3) continue to carry out the filter pu...

Abstract

The invention relates to a purifying process for extraction liquor of reconstituted tobacco. The purifying process comprises steps as follows: clear water or / and the tobacco raw material extraction liquor is / are used for pulping, clear water slurry or / and extraction liquor slurry is / are prepared and conveyed into a plate type sealed leaf filter by a slurry pump, and a filter bed layer is formed on the surface of a filter screen of the filter; then the extraction liquor slurry is conveyed into the plate type sealed leaf filter with the formed filter bed layer by the slurry pump for filtration and purification, the purified extraction liquor is collected into a clear liquor storage tank for subsequent concentration application, and the purified extraction liquor is finally conveyed to a concentration section of a production process of the reconstituted tobacco for concentration production. The purifying process has a good purifying effect on the extraction liquor of the reconstituted tobacco without waste slag, thereby being clean and environment-friendly; process equipment is simple and easy to maintain, so that the system operation cost is low.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaf production by papermaking method. Background technique [0002] At present, the domestic production method of reconstituted tobacco leaves by papermaking method is to use tobacco leaf fragments, tobacco stems and other non-tobacco fibers produced during cigarette processing as raw materials, after solvent extraction, concentration of the extract to make coating liquid, and use of the extracted solids to make paper The process principle of the method is to obtain reconstituted tobacco leaves that can be used by the cigarette industry through the production processes of beating, copying, molding, backcoating of coating liquid, drying and slitting. The extract after solvent extraction is purified. The existing purification treatment methods for the extract mainly use a combination of a vibrating screen and a centrifuge for treatment, or add a chemical flocculant followed by sedime...
