Embodiment 1

[0024] The tobacco stems and tobacco dust used in the experiment were provided by Guangdong China Tobacco Industry Co., Ltd., which were conventional commercially purchased tobacco stems and tobacco dust. The tobacco stems and tobacco dust were refrigerated at 4°C and packed into bags to balance the moisture for later use.

[0025] Single-stage immersion extraction: the experiment of single-stage immersion extraction of tobacco stems and tobacco dust was carried out in a digital constant temperature water bath (Jinyi HHS water bath was used in this example). First put the tobacco stems and tobacco powder into a polyethylene sealed bag, add a certain volume of distilled water, and put them into water baths that have been raised to different temperatures to keep warm. During the immersion extraction, rub it every 10 minutes to make the reaction even. After the single-stage immersion extraction is completed, it is squeezed and dehydrated in a 120-mesh polyester net, and the extra...

Embodiment 2

[0085] Example 2 Effect of the Proportion of Tobacco Stem and Tobacco Powder on the Properties of Tobacco Sheet Paper Base

[0086] The tobacco stems and tobacco powder used in the experiment were provided by Guangdong China Tobacco Industry Co., Ltd., which were commercially available tobacco stems and tobacco powder. Refrigerate the tobacco stems and tobacco powder at 4°C, and pack them into bags to balance the moisture for later use.

[0087] (1) Dipping extraction

[0088] 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.). 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 cooking, keep ...

Embodiment 3

[0123] The preparation technology optimization experiment of embodiment 3 steeping extract

[0124] Tobacco stems and tobacco powder materials are the same as in Example 2 and Example 3.

[0125] (1) Single-stage immersion extraction method: The single-stage immersion extraction experiment of tobacco stems and tobacco dust was carried out in a digital display constant temperature water bath (Jinyi HHS type). First put the tobacco stems and tobacco powder into polyethylene sealed bags respectively, add a certain volume of distilled water according to the experimental conditions, put them in a water bath that has been raised to the required temperature, and keep warm for a specified time. During the immersion extraction, rub it every 10 minutes to make the reaction even. After the single-stage immersion extraction is completed, it is squeezed and dehydrated in a 120-mesh polyester net, and the extract is collected for corresponding chemical analysis.

Abstract

A tobacco sheet is prepared by papermaking method. The method comprises soaking to extract tobacco stem and tobacco powder, and filtering to obtain extractive solution and residue; subjecting the residue to pulping, sheet-making, squeezing and drying to obtain sheet base; and coating the extractive solution on the sheet base. The invention studies influence of different stem/powder pulp ratios on tobacco sheet quality, comprehensively analyzes single action and mutual complex influence relationship of these factors, precisely determines suitable stem/powder pulp ratio, effectively improves physical properties, chemical composition, tensile index, tearing index, bulkiness, density, air permeability, filling value, wettability and permeability of tobacco sheet base, and provides powerful technical support for further improving and stabilizing tobacco sheet quality.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet production, and in particular relates to a preparation method of tobacco sheet. 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] The use of tobacco stems and tobacco dust to prepare tobacco sheets is a current research hotspot. Tobacco flakes can be produced by using tobacco waste such as tobacco stems and tobacco powder through certain processing techniques, and one of the production methods is papermaking. The tobacco sheet produced by the papermaking method has the advantages of low density, large filling value, good mechani...
