Preparation method for peripherally heated non-burning cigarette shreds

Abstract

The invention discloses a preparation method for peripherally heated non-burning cigarette shreds. The method comprises the following steps that 1, the moisture content of reconstituted tobacco is increased; 2, spices and a smoke generating agent are added into the reconstituted tobacco, and the moisture content of the reconstituted tobacco is increased, wherein the spices and the smoke generatingagent account for 5-30% of the weight of the tobacco; 3, the reconstituted tobacco in step 2 is cut into tobacco shreds; 4, the moisture content of the tobacco shreds is decreased at the low temperature; 5, the temperature of the tobacco shreds is lowered to the room temperature with low-humidity and dried air, and the moisture content is decreased to 9-14 wt%; 6, the spices and the smoke generating agent are added into the tobacco shreds for uniform mixing to obtain the heated non-burning cigarette shreds, wherein the addition quantity of the spices and smoke generating agent accounts for 0.5-7% of the weight of the tobacco shreds, and step 4 can be omitted. According to the method, the original flavor in the tobacco is not destroyed, the spices and the smoke generating agent which are added into the tobacco shreds are maintained to the maximum limit, the taste of smoke is improved, and the smoke amount is increased.

Description

technical field [0001] The invention belongs to the technical field of shredded tobacco, in particular to the technical field of using reconstituted tobacco leaves to manufacture shredded tobacco of peripheral heat-not-burn cigarettes. Background technique [0002] Heat-not-burn cigarettes are a new type of cigarettes in which smoking substances are baked at low temperatures to generate smoke for smokers to inhale. Because of its low temperature and non-combustible shredded tobacco, it can greatly reduce the production of harmful substances. Since heat-not-burn cigarettes can better adapt to the ban on smoking in public places and satisfy the preferences of tobacco consumers to a certain extent, the market demand for heat-not-burn cigarettes is growing rapidly.

Problems solved by technology

[0003] Chinese patent CN 104770852 discloses a separate silk-making process suitable for paper-making reconstituted tobacco leaf production plants, including the following steps: storage, shredding, feeding, temporary storage, temperature increase and humidification, drying silk, purification, blending and other steps, Aiming at the processing characteristics of reconstituted tobacco leaves by the papermaking method, the separate shreds are realized; the feeding step of this preparation method is after shredding. The materials added in the steps of wet, shred drying, and purification are lost, and the obtained shredded tobacco needs to be directly blended with other shredded tobacco, and the shredded tobacco alone is not suitable for peripheral heat-not-burn cigarettes

[0004] Chinese patent CN 102178337 B discloses a separate silk-making process and equipment based on the processing characteristics of reconstituted tobacco leaves by the papermaking method. The process includes the following process steps: unpacking, shoveling, loosening, regaining moisture, shredding, drying, and blending processes; In the preparation method, there is no fuming agent and tobacco fusion step in the preparation process, and the amount of smoke used in heat-not-burn cigarettes is insufficient, and the taste of smoking is monotonous; at the same time, the shredded tobacco obtained by the preparation method needs to be directly blended with other shredded tobacco before use, even Such blended shredded tobacco is still unsuitable for peripheral heat-not-burn cigarettes

Existing central heat-not-burn cigarettes generally cannot be used in peripheral heating smoking appliances
