Embodiment 1

[0031] Tobacco stems and tobacco dust used in the experiment were randomly selected from the raw materials produced by Guangdong China Tobacco Industry Co., Ltd., and were commercially available tobacco stems and tobacco dust. Refrigerate the tobacco stems and tobacco powder at 4°C, and pack them into bags to balance the moisture for later use.

[0032] The maceration extraction and refining treatment of tobacco stems and tobacco dust refer to existing routines.

[0033] The pulp after refining is copied by Austrian PTI fast sheet copying machine, and the quantitative is 70g / m 2 For the thin paper base for cigarettes, for the convenience of description, the mass ratio of tobacco stem pulp to tobacco dust pulp used in this embodiment is 7:3. A KRK-2570 square press (Japan KRK Company) was used to press and then dry with different pressing pressures. The drying temperature used in this embodiment was 105°C. The paper sheets were treated under ISO standard constant temperature ...

Embodiment 2

[0061] Example 2 Comprehensive Research on the Preparation Technology of Sheets for Tobacco

[0062] Tobacco stems and tobacco dust used in the experiment were randomly selected from the raw materials produced by Guangdong China Tobacco Industry Co., Ltd., and were commercially available tobacco stems and tobacco dust. Refrigerate the tobacco stems and tobacco powder at 4°C, and pack them into bags to balance the moisture for later use.

[0063] (1) Dipping extraction

[0064] In this example, the single-stage immersion extraction experiment of tobacco stems and tobacco powder was carried out in an electric cooking pot (ordinary type) ZT1-00 / 15L (produced by Xingping Zhongtong Experimental Equipment Co., Ltd.).

[0065] Tobacco stem extraction: The amount of tobacco stems in the pot is 1500g. First add about 10000mL of water into the cooking pot according to the liquid ratio of 1:7 (mass ratio), preheat to 60°C, add the tobacco stems, cover the pot and carry out rotary cooki...

Embodiment 3

[0101] The preparation of embodiment 3 reconstituted tobacco leaves

[0102] Tobacco stems and tobacco dust used in the experiment were randomly selected from the raw materials produced by Guangdong China Tobacco Industry Co., Ltd., and were commercially available tobacco stems and tobacco dust. Refrigerate the tobacco stems and tobacco powder at 4°C, and pack them into bags to balance the moisture for later use.

[0103] (1) extracting tobacco stems and tobacco powder

[0104] Tobacco stems and tobacco dust are extracted by a three-stage countercurrent extraction process, and the schematic diagram of the process flow is shown in the appendix Figure 4shown. Tobacco stems and tobacco powder enter the refining section after the first stage extraction, the second stage extraction and the third stage extraction respectively. The third-stage extraction uses clean water to extract the third-stage extract liquid that enters the second stage countercurrently for immersion extracti...

Abstract

The invention discloses a method for preparing reconstituted tobacco leaves from tobacco stem tobacco powder. The reconstituted tobacco leaf is prepared by a papermaking method, soaking and extracting tobacco stems and tobacco dust, filtering the extract, and soaking processed tobacco stem residues and tobacco residues; the tobacco stem residues and tobacco residues are refined, sliced, Squeeze and dry to obtain a thin paper base; use the extract as a coating solution to backcoat on the thin paper base for cigarettes. The present invention systematically studies the pressing process, provides definite pressing process conditions, and effectively improves the physical properties, chemical composition, tensile index, tear index, bulk, tightness, air permeability, and Filling value, wettability and permeability, comprehensively improve the surface properties and internal structure of the sheet paper base, and improve the running performance and effectiveness of the tobacco sheet production line.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for preparing reconstituted tobacco leaves from tobacco stem tobacco. Background technique [0002] During the rebaking of tobacco leaves and the production of cigarettes, tobacco waste such as tobacco stems and tobacco powders, which account for about 1 / 3 of the total amount of raw tobacco materials, will be produced. In my country, hundreds of thousands of tons of tobacco stem resources are discarded every year, resulting in waste of resources and environmental pollution. [0003] Reconstituted tobacco leaves are reconstituted tobacco leaves produced through certain processing techniques using tobacco waste such as tobacco stems and tobacco dust produced during tobacco processing. The reconstituted tobacco produced by the papermaking method has the advantages of low density, large filling value, good mechanical properties, and low tar content,...
