Extract liquor purification treatment method for paper-making reconstituted tobacco

Abstract

The invention discloses an extract liquor purification treatment method for paper-making reconstituted tobacco. The method comprises following steps: 1, putting tobacco materials containing tobacco stems, fragments and tobacco waste into an extraction tank employing water as an extraction solvent, performing solid-liquid separation after the extraction so as to obtain the solid and the extract liquor, wherein the solid is used for pulping and paper-making so as to form the paper base; 2, putting functional fibers into a hydro-pulper for pulping, and performing beating after the pulping; 3, sandwiching the beaten functional fibers between two filter screen layers to form a filter cake layer, and enabling the extract liquor to penetrate the filter cake layer; or directly adding the pulped functional fibers into the extract liquor, allowing the extract liquor to stand after the extract liquor is fully stirred, and adding guar gum into the extract liquor so as to make the functional fibers to fully and rapidly flocculate; and 4, purifying the extract liquor sequentially through a mesh screen and a horizontal screw decanter centrifuge, enabling the purified extract liquor to penetrate a condensation device for condensation, dip-coating the concentrated solution on the paper base, and drying and cutting the paper base so as to obtain the tobacco. According to the invention, the clarity degree of the extract liquor is improved by 35.23%, the color is bright, and the taste is improved.

Description

technical field [0001] The invention relates to a method for purifying an extract of reconstituted tobacco leaves by a papermaking method, and belongs to the technical field of tobacco preparation. Background technique [0002] The production process of paper-making reconstituted tobacco leaves is to extract the tobacco raw materials such as tobacco stems and fragments, and then separate the solid and liquid. As a homogenized carrier in the production process, the paper base only plays the role of bearing and adsorption. The quality of the tobacco extract directly determines the physical and chemical properties and sensory quality of the final product. In addition to the main tobacco aroma components in the extract In addition, it also contains solid particles such as sediment and fibers on the surface of the raw material, and macromolecular suspensions such as starch, protein, wax, and lipid. Weak, resulting in low coating rate of finished products, large fluctuations in b...

Problems solved by technology

As a homogeneous carrier in the production process, the paper base only plays the role of bearing and adsorption. The quality of the tobacco extract directly determines the physical and chemical properties and sensory quality of the final product. In addition to the main tobacco aroma components contained in the extract In addition, it also contains solid phase particles such as sediment and fiber on the surface of raw materials and macromolecular suspended matter such as starch, protein, wax, and lipid. On the one hand, these substances will cause the solid content and viscosity of the extract to be large, and the permeability Weak, resulting in low coating rate of finished products, large fluctuations in batch product quality, affecting the sensory quality of products; on the other hand, it will also cause equipment blockage during production, affecting the continuous operation of production

[0003] The papermaking reconstituted tobacco industry basically adopts physical impurity removal methods such as filtration and centrifugation, but simple physical methods can only remove part of the larger solid particles, and the effect on tiny solid particles and macromolecular solid suspended matter is very insignificant For this reason, many research units have conducted a lot of research on the treatment methods of the extract, and proposed a large number of treatment methods such as flocculant treatment, adsorbent adsorption, biological enzymatic hydrolysis, and improvement of separation equipment, while using functional fibers to purify the extraction Liquid research has not been reported
