Problems solved by technology

[0004] The conventional coating process has the following problems in the production of heat-not-burn reconstituted tobacco leaves: it is difficult for the coating liquid to penetrate into the inside of the substrate, and a shell will be formed outside the substrate. Once the moisture absorbs the reconstituted tobacco leaves will stick together and affect the subsequent processing Phenomena such as paper breakage and coating rate not up to standard in the final product occur from time to time

Abstract

The embodiment of the invention provides a coating method and device for heating non-combustion reconstituted tobacco, and relates to the field of tobacco production processes. The coating method comprises the following steps: backfilling a substrate with a coating liquid to obtain a tobacco semi-finished product; heating the tobacco semi-finished product by using steam at a preset temperature; and extruding the heated tobacco semi-finished product to adjust the thickness of the tobacco semi-finished product. According to the invention, the steam wet heating operation process and the step of extruding the wet tobacco semi-finished product are added, the permeability of the coating liquid to the substrate can be improved, the phenomena such as adhesion and caking which are not beneficial to follow-up processing are avoided, meanwhile, the thickness of the product can be effectively adjusted, the physical performance of the product is improved, and the use feeling of the cigarette is increased. Besides, according to the coating device, mechanisms in different process stages are arranged so that the substrates can be subjected to assembly line work on the coating device, and finally obtained tobacco leaves are good in physical performance and use feeling.

Description

technical field [0001] The invention relates to the field of tobacco leaf production technology, in particular to a coating method and device for heat-not-burn reconstituted tobacco leaves. Background technique [0002] The production process of heat-not-burn reconstituted tobacco leaves is a separation-recombination process of tobacco substances. During the production process, the tobacco raw materials are divided into two parts: solvent-soluble and insoluble by extraction and separation technology. The intermediate product of the reconstituted tobacco leaf is formed by other process links - the substrate, and the soluble matter is purified, concentrated, and blended to form another intermediate product - the coating liquid. Burning reconstituted tobacco leaves. [0003] The conventional coating process is to send the configured coating liquid to the coating machine through the coating feeding system, backfill the coating liquid into the substrate through the coating rolle...
