A kind of preparation method of reconstituted tobacco leaf

Abstract

The invention provides a method for preparing reconstituted tobacco leaves. The preparation method comprises the following steps: extracting tobacco raw materials to obtain extracts and solid slag, passing the tobacco extract through a decanter centrifuge and a disc separator, and then passing Activated carbon adsorption device A and activated carbon adsorption device B obtain the concentrated liquid of tobacco refining liquid B, and then obtain the finished reconstituted tobacco leaves after concentration, beating, coating, drying and cutting. The present invention utilizes the adsorption of different activated carbons, adopts coal-based columnar activated carbon to absorb part of the protein, pectin and other macromolecular substances in the tobacco extract, and adopts coconut shell granular activated carbon to absorb part of the nicotine and total nitrogen in the tobacco extract. , total sugar and other components, so as to achieve the purpose of regulating the chemical components of reconstituted tobacco leaves and improve the quality of reconstituted tobacco leaves.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, in particular to a preparation method of reconstituted tobacco leaves. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco sheets, homogenized tobacco leaves or reconstituted tobacco leaves, have the characteristics of high filling value, good combustion performance, and low tar release. The use of reconstituted tobacco leaves to replace or partially replace traditional cut tobacco to prepare cigarettes is a way of reducing coke and harm. one of the effective means. [0003] Paper-making reconstituted tobacco leaves are made of tobacco stems, tobacco leaf fragments, tobacco powder, etc. as raw materials, and the paper-making process is used to make reconstituted tobacco leaves with properties close to natural tobacco leaves. An important measure and implementation carrier in technology, reconstituted tobacco leaves can effectively utilize tobacc...

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
