Embodiment 1

[0030] Add cationic guar gum with a molecular weight of 500,000 slowly into water under stirring conditions, dilute to 1% by mass, stir thoroughly for 30 minutes, then heat the solution to 40°C, keep stirring for 90 minutes and then stir for later use.

[0031] Dilute the dissolved cationic guar gum to 0.1% (mass percentage), stir well, and then add it to the tobacco powder extract to be filtered, the addition amount is 0.4% (relative to the dry mass ratio of tobacco powder), at 500 rpm / min speed stirring for 3 minutes, and then sent to the filter for dehydration.

[0032] Compared with the control group without cationic guar gum, the unit filtration time was shortened by 40%, and the filtration efficiency was significantly improved. The average number of equipment unpacking and washing in the control group without adding cationic guar gum was 21 times / month. After filtering with cationic guar gum in this example, the average number of equipment dismantling and washing was 1...

Embodiment 2

[0034] First add cationic guar gum with a molecular weight of 500,000 to water slowly under stirring conditions, dilute to 1% by mass, stir thoroughly for 30 minutes, then heat the solution to 40°C, keep stirring for 90 minutes and then stir for later use .

[0035] The dissolved cationic guar gum is diluted to 0.1% (mass percentage), and fully stirred, and the diluted cationic guar gum is added from the pipeline through a metering pump in an amount of 0.3% relative to the absolute dry mass ratio of the tobacco powder. The pipe is the pipe located after the slurry pump of the smoke extraction equipment and before entering the filter.

[0036] Compared with the control group without the addition of cationic guar gum, the filtration efficiency was improved, because the equipment dismantling and cleaning time caused by the clogging of the filter screen was reduced by 41%.

Embodiment 3

[0038] First, add cationic guar gum with a molecular weight of 350,000 to water slowly under stirring conditions, dilute to 1% by mass, stir thoroughly for 20 minutes, then heat the solution to 30°C, keep stirring for 60 minutes, and then stir for later use .

[0039] Dilute the dissolved cationic guar gum to 0.1% (mass percentage), stir well, and then add it to the tobacco powder extract to be filtered, the addition amount is 0.5% (relative to the absolute dry mass ratio of the tobacco powder), at 600 rpm / min speed stirring for 2 minutes, and then sent to the filter for dehydration.

[0040] Compared with the control group without the addition of cationic guar gum, the filtration efficiency was improved, because the equipment disassembly and cleaning time due to filter blockage was reduced by 31%.

Abstract

The invention discloses a method for improving the filtering efficiency of a tobacco powder extracting solution during production of tobacco sheets through a paper-making process. The method comprises the steps of firstly, preparing a proper cationic guar gum solution, then diluting into a solution with the mass concentration of 0.1-0.3%, and adding into the tobacco powder soaking and extracting solution to be filtered for filtering according to the proportion of 0.2%-0.6% of the absolute dry mass of tobacco powder. The method is simple and easy to implement, appropriate and practical cationic guar gum is found out through a large amount of experiments, by the aid of the method, the draining efficiency of the tobacco powder can be improved, device blockage times can be reduced by 20%-40%, the production efficiency can be improved, the working amount of operators can be reduced, and the method has great values in industrial production of tobacco sheets.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for improving the filtration efficiency of tobacco powder extract liquid in the production process of paper-making tobacco sheets. Background technique [0002] The process of producing tobacco sheets by papermaking method is as follows: (1) After leaching the tobacco stems and tobacco dust and other wastes in the tobacco production process, they are filtered and separated to obtain the extract and filter residue; (2) Concentrate the extract, Appropriately adding additives such as flavors and spices to prepare a coating solution; (3) The filter residue is prepared into tobacco stem pulp and tobacco powder pulp by mechanical pulping, and the pulp is prepared, and the paper machine is used to make a sheet paper base; (4) The coating solution is back-coated on the sheet paper base through a surface sizing coating method to prepare a paper-making tob...
