Embodiment 1

[0050] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in 40°C hot water and 30°C for 1.5 hours respectively, and extracted to obtain tobacco stem extract and tobacco leaf fragment extract; the tobacco stem extract was discarded, and the tobacco leaf fragment extract was subjected to centrifugal filtration and reverse osmosis The membrane is concentrated, and then concentrated under vacuum and reduced pressure. The final concentrated solution is dip-coated on the formed substrate, dried, punched, and formed.

[0051] The thin slice better maintains the original fragrance of tobacco, can feel obvious tobacco smell, and has good smoking quality. The internal quality comparison is shown in the table below. The test sample is a new process sample, and the control is a sample that does not use the membrane concentration process.

Embodiment 2

[0055] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in 70°C hot water for 1 hour and 60°C for 0.5 hour, respectively, and extracted to obtain tobacco stem extracts and tobacco leaf fragments extracts. The extract of mixed tobacco stems and tobacco leaf fragments is centrifugally filtered, concentrated by reverse osmosis membrane, and then concentrated by vacuuming and decompression. The final concentrated solution is dip-coated on the formed sheet substrate, dried, sliced, and formed.

[0056] The thin slice better maintains the original aroma of tobacco, can feel obvious tobacco smell, and has better smoking quality. The internal quality comparison is shown in the table below. The test sample is a new process sample, and the control is a sample that does not use the membrane concentration process.

Embodiment 3

[0059] 700kg of tobacco stems and 700kg of tobacco leaf fragments were soaked in 70°C hot water for 1 hour and 60°C for 0.5 hour, respectively, and extracted to obtain tobacco stem extracts and tobacco leaf fragments extracts. The extract of tobacco leaf fragments is centrifugally filtered and concentrated by a reverse osmosis membrane; the extract of tobacco stems is centrifugally filtered and then filtered by an ultrafiltration membrane to obtain a permeate, which is then concentrated by a reverse osmosis membrane. Combining the concentrated solution of tobacco stems and fragments and then concentrating under vacuum and reduced pressure; the final concentrated solution is dip-coated on the shaped substrate, dried, punched, and shaped.

Abstract

The invention discloses a method for concentrating a tobacco extraction liquid in the production of a tobacco sheet by a papermaking process, which comprises the following steps of: a, extracting tobacco stems and tobacco fragments by water or ethanol solution respectively, and then performing solid-liquid separation; b, obtaining an tobacco fragment extraction liquid, a tobacco stem extraction liquid or one of the tobacco fragment extraction liquid and the tobacco stem extraction liquid for centrifugal filtration, and then concentrating a filtrate through a reverse osmosis membrane; and c, then performing vacuum decompression concentration or spray drying concentration on concentrated solution. The method solves the problems that the tobacco sheet by the papermaking process has poorer inherent smoking quality and plain tobacco fragrance and how to furthest utilize waste tobacco during the processing of cigarettes, reasonably utilizes the resource, and improves the inherent quality of the cigarettes. The tobacco sheet prepared by the method has better taste and full and natural tobacco fragrance.

Description

technical field [0001] The invention belongs to the field of tobacco sheet production, and in particular relates to a method for concentrating water or ethanol solution extracts of tobacco waste materials such as tobacco stems and tobacco leaf fragments in the production of tobacco sheet by papermaking method. Background technique [0002] Tobacco flakes are reconstituted tobacco leaves that are recombined and processed from tobacco waste materials such as tobacco dust, tobacco stems, tobacco leaf fragments and some low-grade tobacco leaves during the cigarette processing process. On the one hand, the raw materials of tobacco leaves can be utilized to the greatest extent, and the cost of cigarettes can be saved; on the other hand, tobacco sheets play an important role in reducing the release of cigarette tar and reducing the harm of cigarettes. With the public's attention to smoking and health, the country's control over the tar of cigarette products is increasingly strength...
