Reconstituted tobacco preparation method

Abstract

The invention provides a reconstituted tobacco preparation method. The preparation method includes steps: extracting tobacco raw materials to obtain extraction liquid and solid residues; allowing thetobacco extraction liquid to pass through a horizontal screw centrifuge and a disc separator sequentially and then pass through an activated carbon adsorption device A and an activated carbon adsorption device B to obtain tobacco refined solution B concentrated liquid, and performing concentrating, beating, coating, drying and slitting to obtain a finished product of reconstituted tobacco. Due todifferent activated carbon adsorption effects, macromolecular substances including part of proteins, pectin and the like in the tobacco extraction liquid are adsorbed by coal columnar activated carbonwhile components including nicotine, total nitrogen, total sugar and the like in the tobacco extraction liquid are adsorbed by coconut shell granular activated carbon, and accordingly regulation of chemical components of the reconstituted tobacco is realized, and quality of the reconstituted tobacco is improved.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a preparation method of reconstituted tobacco leaves. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco flakes, homogeneous tobacco leaves or reconstituted tobacco leaves, have the characteristics of high filling value, good combustion performance, and low tar release. Using reconstituted tobacco leaves to replace or partially replace traditional shredded tobacco to prepare cigarettes is the best way to reduce tar and harm in cigarettes. one of the effective means. [0003] Paper-making reconstituted tobacco leaves use tobacco stems, tobacco leaf fragments, and tobacco dust as raw materials, and uses papermaking technology to make reconstituted tobacco leaves that are close to natural tobacco leaves. In recent years, paper-making reconstituted tobacco leaves are gradually becoming the key core of "improving quality ...

Problems solved by technology

The biodegradation method realizes the selective degradation of chemical substances through the screened strains or enzyme preparations, and achieves the purpose of regulation, but the reaction time is often long and it is not suitable for large-scale; the electrodialysis method is mainly used to reduce the content of chloride ions or nitrates , but the investment is large and the capacity is low; the membrane separation method can separate substances outside certain size ranges through the selective action of the membrane pore size, and the selective separation of chemical components can be achieved through the selection and combination of membranes with different pore sizes, but the same There are problems of large investment and limited processing capacity
