The invention discloses a filter stick for a cigarette. The filter stick comprises an acetate fiber filter stick section, an active carbon filter stick section and a middle section, wherein the acetate fiber filter stick section is connected with the middle section; the middle section is positioned between the acetate fiber filter stick section and the active carbon filter stick section; and the active carbon filter stick section is connected with a cigarette body. Due to the adoption of the filter stick, the using quantity of acetate fiber tows is reduced, the consumption of wood pulp is lowered, and the natural environment is protected. The middle section is introduced, so that the design flexibility of a cigarette product is enhanced. By changing the lengths and pressure drops of three sections of materials, a ternary composite filter stick with different filtering efficiencies can be designed to meet the requirements of different products. Various functional tar reducing and harm relieving additives can be loaded into the middle section of the cigarette, so that a cigarette with low tar content and low harm is produced. Moreover, the active carbon filter stick is compounded in the filter stick, so that the functions of harmful substances in the cigarette can be weakened, and the smoking safety of the cigarette is enhanced.

The invention discloses a novel tobacco humectant and a novel tobacco humectant application method. The novel tobacco humectant is natural propolis extractive or mixing solution of the natural propolis extractive and propylene glycol, glycerol or sorbitol, and the weight proportion of the natural propolis extractive and water, the propylene glycol, the glycerol or the sorbitol is 10-90%:90-10%. The novel tobacco humectant is sprayed evenly on tobacco, and the spraying proportion is 0.1-1.0% of the weight of the tobacco. The moisture content in the tobacco is measured according to the method stipulated by YC / T28.8-1996 Moisture Measurement of Cigarette Physical Properties. The result shows that the effect of the novel tobacco humectant is better than the widely-used traditional humectant such as the propylene glycol, the glycerol or the sorbitol at present.

The invention provides raw materials for cigarettes, a production method of the raw materials for the cigarettes and equipment of the raw materials for the cigarettes. The production method of the raw materials for the cigarettes includes the following steps. Firstly, plant biomass is heated and moistened unit the water content reaches 35 wt% to 40 wt%. Secondly, materials are preheated after being heated and moistened until the water temperature of the materials reaches the boiling point. Thirdly, the preheated materials are expanded with micro waves until the water content reduces to 10 wt% to 20 wt%. Fourthly, water is added to the materials until the water content reaches 30 wt% to 40 wt%. Fifthly, the materials are machined to be fiber shreds. Sixthly, biological enzyme liquid is sprayed onto the fiber shreds, the fiber shreds with the biological enzyme liquid are soaked in water. Seventhly, drying is performed. The raw materials for the cigarettes, the production method of the raw materials for the cigarettes and the equipment of the raw materials for the cigarettes overcome defects in the prior art, have the advantages that water consumption in production is low, crushed raw materials for the cigarettes obtained in production are less, compatibility with tobacco shreds is perfect, woodiness texture is not obvious and can be applied to manufacture of high-grade cigarettes.

The invention discloses a method for reducing crotonaldehyde in mainstream smoke of cigarettes, which includes: packing tobacco / finished cigarettes with paper cartons with a stacking thickness of 26-72cm and a stacking density of 0.20-0.34g / cm<3>; placing the cigarette cartons on a conveying device at the conveying speed of 0.02-0.3m / s, and subjecting the cartons to electronic beam / X-ray irradiation generated by an electronic accelerator, wherein the electronic accelerator is 5-10MeV in energy, 0.3-20mA in beam current, 10-20kW in beam power, 100cm in largest scanning width, 5-15Hz in scanning frequency, 1-10kGy in irradiation dose and 5-35 DEG C in set operating temperature; allowing the cartons to pass a scanning widow of the electronic accelerator twice for irradiation, wherein the distance from the center of each carton to the scanning window of the electronic accelerator is 40-60cm in irradiation; and limiting the ambient humidity to be no larger than 60% in operation.

The invention provides a manufacturing method for a low-phenol paper-process reconstituted tobacco leaf. One portion of reconstituted tobacco leaf raw materials is taken according to parts by weight, 3 to 10 portions of ethanol (50 to 95%) are added, the backflow extraction is carried out for 50 to 70 minutes, and then extracted mixed solution is obtained and separated to obtain a solid phase part an a liquid phase part; the liquid phase part recycles the ethanol through vacuum concentration; the solid phase part is put into 4 to 10 portions of water after being dried till the moisture content is within 8 to 15% and is then extracted for 40 to 50 minutes under the temperature of 50 to 90 DEG C, so as to obtain the extracted mixed solution; vacuum concentration is carried out on the liquid phase part obtained by the separation of the extracted mixed solution till the density is within 1.1 to 1.3g / cm3, and the liquid phase part is adopted as a coating material; the solid phase part is defibered into a fiber sizing agent, the beating degree of the fiber sizing agent is within 20 to 400SR, the fiber sizing agent is diluted by water to obtain a papermaking seizing agent, and a substrate is prepared through papermaking; finally, the coating material is coated on the substrate, so as to obtain the finished reconstituted tobacco leaf through drying and split-cutting; and the reconstituted tobacco is a mixture containing one or two kinds of cabo, tobacco leaf and minced tobacco. The manufacturing method in the invention has obvious effect of reducing the phenol releasing quantity in smoke of the paper-process reconstituted tobacco leaf.
