Abstract

The invention provides a manufacturing method for a low-phenol paper-process reconstituted tobacco leaf. One portion of reconstituted tobacco leaf raw materials is taken according to parts by weight, 3 to 10 portions of ethanol (50 to 95%) are added, the backflow extraction is carried out for 50 to 70 minutes, and then extracted mixed solution is obtained and separated to obtain a solid phase part an a liquid phase part; the liquid phase part recycles the ethanol through vacuum concentration; the solid phase part is put into 4 to 10 portions of water after being dried till the moisture content is within 8 to 15% and is then extracted for 40 to 50 minutes under the temperature of 50 to 90 DEG C, so as to obtain the extracted mixed solution; vacuum concentration is carried out on the liquid phase part obtained by the separation of the extracted mixed solution till the density is within 1.1 to 1.3g / cm3, and the liquid phase part is adopted as a coating material; the solid phase part is defibered into a fiber sizing agent, the beating degree of the fiber sizing agent is within 20 to 400SR, the fiber sizing agent is diluted by water to obtain a papermaking seizing agent, and a substrate is prepared through papermaking; finally, the coating material is coated on the substrate, so as to obtain the finished reconstituted tobacco leaf through drying and split-cutting; and the reconstituted tobacco is a mixture containing one or two kinds of cabo, tobacco leaf and minced tobacco. The manufacturing method in the invention has obvious effect of reducing the phenol releasing quantity in smoke of the paper-process reconstituted tobacco leaf.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a method for manufacturing reconstituted tobacco leaves by papermaking method with low phenol release. Background technique [0002] The State Tobacco Monopoly Administration clearly put forward the goal of “reducing harm and reducing coke” of cigarette products, and determined the reduction of phenol, carbon monoxide, benzo[α]pyrene, crotonaldehyde, NH 3 , HCN, and NNK seven harmful ingredients to carry out the work of "reducing harm and reducing coke". As a new raw material for cigarettes, paper-making reconstituted tobacco leaves are urgently needed to develop reconstituted tobacco leaves that can reduce harmful components such as phenol, so as to promote the realization of "harm reduction and tar reduction" in cigarettes. However, there is currently no effective method for producing reconstituted tobacco leaves with a lower phenol release. ...
