Problems solved by technology

However, the reconstituted tobacco leaves produced by the existing dry-process papermaking technology are finally attached to the surface of the substrate as a dried product composed of tobacco powder and adhesive. When the slices are cut into shreds, the edge end face is very easy to lose powder, resulting in a high powder loss rate and severe dust, which affects product quality and production environment.
Due to the use of a large amount of adhesives to fix the tobacco powder, the smoking quality and quality of the reconstituted tobacco leaves will also be affected to a certain extent due to the excessive use of adhesives

Embodiment 1

[0029] The plant fibers are defibrated into single fibers and sent to the first shaper (1) by air, and under the protection of the negative pressure box (6), a fiber layer (7) of 10g / m2 is formed, and the tobacco chips are passed through the spreader ( 3) Measuring and spreading on the first former (1), and laying a layer of tobacco fragments on the formed fiber thin layer, the quantity of tobacco fragments is 10g / m2. Then on the fiber layer covered with tobacco chips, under the negative pressure protection of the negative pressure box (6) by the second shaper (2), a layer of fiber is laid on it, and the amount of fiber laying is 10g / m2, like this Just formed a combined composite fiber layer (8) that is sandwiched with tobacco fragments in the middle of the upper and lower fiber layers. After the pre-pressing by the pre-pressing hot roller (5), the substrate prototype is formed. At this time, the substrate has not been sprayed with adhesive, and its strength is low. On the fo...

Embodiment 2

[0031] After the plant fiber is defibrated, it is sent to the first former (1) by air, and under the protection of the negative pressure of the negative pressure box (6), a fiber layer (7) with a weight of 10g / m2 is formed, and then formed by the second Under the negative pressure protection of the negative pressure box (6), the device (2) lays another layer of fiber layer on the fiber layer (7), the weight of the newly laid fiber layer is 8g / m2, thus forming a fiber layer of 18g / m2 (8), pre-pressed by the pre-pressing hot roller (5) to form a substrate prototype composed of fiber layers. At this time, the formed substrate has no strength. On the formed substrate, a certain amount of adhesive is sprayed on the upper and lower sides , under the protection of the negative pressure of the negative pressure box (11) and the negative pressure box (17), the adhesive is attached to the substrate, and has a certain penetration, and is dried by the drying box (14, 15, 18, 19) Then ther...

Embodiment 3

[0033] The plant fibers are defibrated into single fibers and sent to the first shaper (1) by air. Under the protection of the negative pressure of the negative pressure box (6), a fiber layer (7) of 10g / m2 is formed. The spreader (3) measures and spreads on the fiber layer (7) formed by the first former (1), spreads a layer of tobacco chips, the tobacco chips are quantitatively 10g / m2, and then spreads on the fiber layer covered with tobacco chips , under the protection of the negative pressure of the negative pressure box (6) by the second shaper (2), a layer of fiber is laid on it, and the amount of fiber laying is 10g / m2, thus forming a sandwich between the upper and lower fiber layers The combined fiber layer (8) with tobacco fragments has just formed the base sheet prototype after pre-pressing with the pre-pressing hot roller (5). At this time, the substrate is not sprayed with adhesive, and its strength is low. On the formed substrate, the upper and lower sides are spr...

Abstract

The present invention provides a method for regenerating tobacco leaves by loaded tobacco fragments manufactured by a dry papermaking technology, and belongs to the field of a tobacco product machining method. The method comprises the following two steps: step 1, sorting the tobacco fragments and adding the tobacco fragments in a substrate forming process, conveying fibers into a first forming device (1) after plant fibers are deliberated into single fiber shapes, and forming a fiber layer (7) by using an airflow net forming method; and step 2, spraying paste prepared from the tobacco fragments, tobacco powder and an adhesive on the formed substrate, i.e. spraying the paste made of the tobacco fragments, the tobacco powder and the adhesive on one surface of the substrate, drying, then spraying the paste made of the tobacco fragments, the tobacco powder and the adhesive on the other surface of the substrate and drying to obtain the tobacco leaves regenerated by the loaded tobacco fragments manufactured by the dry papermaking technology. By virtue of the method, not only can procedures be reduced, but also powder-falling and dust-raising phenomena caused by excessive tobacco powder are reduced, the use amount of the adhesive is also reduced and the smoking quality is improved.

Description

technical field [0001] The invention belongs to the field of tobacco product processing methods, and in particular relates to a new process of reconstituted tobacco loaded with tobacco fragments manufactured by dry-laid papermaking technology. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco flakes, reconstituted tobacco leaves or homogeneous tobacco leaves, are mainly composed of tobacco chips, shreds, tobacco stems or low-grade tobacco leaves, plus some plant fibers, adhesives, flavors and fragrances and other additives. As a raw material of cigarette products, reconstituted tobacco leaves have been widely used in cigarette products because of their low cost and good filling properties. After adding, they can reduce the tar content and some harmful substances in cigarettes. [0003] The reconstituted tobacco leaf began in the 1950s. At the beginning, the thick pulp method and the rolling method were mainly used. Due to the backward technolo...
