Problems solved by technology

[0004] In the production process of reconstituted tobacco leaves, the treatment of tobacco stems is generally regardless of the origin, grade, and physical form (stem diameter and length) of the tobacco stems. Various tobacco stems are mixed together and put into the production line until the finished product is produced; Stem raw materials come from various sources, mixed grades and varieties, low degree of homogenization, unstable batch quality, and great difficulty in control. This relatively extensive processing method does not classify and process the differences in tobacco stem quality, which affects The stability between batches of finished reconstituted tobacco leaves cannot give full play to the utilization value of tobacco stems

Embodiment 1

[0024] The screening and grouping method of the tobacco stem raw material of the present embodiment is carried out as follows:

[0025] The same batch of K326 middle stems from a certain place of origin, the stems with a length > 30 mm were removed and collected as part of the stems; the tobacco stems with the removed stems were grouped according to the following conditions:

[0026] (1) Stem part: the part of the tobacco stem length × diameter ≤ 30 mm × 1.5 mm is used as the part of the stem;

[0027] (2) Thin stem part: the part of 30mm×1.5mm<tobacco stem length×diameter≤30mm×3mm is regarded as the thin stem part;

[0028] (3) The first thick stem part: the part of 30mm×3mm<tobacco stem length×diameter<30mm×4.5mm is taken as the first thick stem part;

[0029] (4) The second thick stalk part: the part whose tobacco stem length×diameter>30mm×4.5mm is regarded as the second thick stalk part.

[0030] The stem part, the thin stem part, the first thick stem part, the second th...

Embodiment 2

[0049] The method for screening and grouping the tobacco stem raw materials in this embodiment is the same as that in Embodiment 1.

[0050] Compound the stalk paste, the thin stalk, the first thick stalk, and the second thick stalk at a mass ratio of 2:4:3:1, and the rest are the same as in Example 1, and the sensory quality evaluation results correspond to No. 7#, as shown in Table 3:

[0051] Table 3 Comparative analysis of sensory quality of different proportions of compound stem ointment

[0052]

[0053] The results show that: 0# control, the aroma quality is still good, the amount of aroma is still sufficient, the richness is slightly lacking, the clarity is slightly lacking, it is irritating, slightly woody, and slightly astringent and hot in the mouth.

[0054] 7# has better aroma quality and aroma clarity, more aroma, more smoke concentration, better richness, and the mouth is more comfortable and clean than 0#.

[0055] The above results show that after groupin...

Embodiment 3

[0057] The method for screening and grouping the tobacco stem raw materials in this embodiment is the same as that in Embodiment 1.

[0058] Mix the stem part, the thin stem part, the first thick stem part and the second thick stem part selected by grouping according to the mass ratio of 2:3:4:1 to obtain a mixed tobacco stem, and mix the mixed tobacco stem with the existing The fragments, tobacco powder, and ash sticks are mixed at a mass ratio of 1:3, and then extracted according to the following process:

[0059] The solid-liquid mass ratio is 1:6, the temperature is 60°C, and the time is 50 minutes; the concentration conditions are: temperature 70°C, vacuum degree 120mbar, rotation speed 80rad / min; extraction twice, the two extracts are combined and then concentrated in vacuum to a density of 1.2g / cm 3 ; Extract twice, and combine the two extracts to obtain the coating solution.

[0060] Apply the coating solution to the base of C1 reconstituted tobacco leaves according ...

Abstract

The invention relates to a screening and grouping method of tobacco stem raw materials and application thereof to reconstituted tobacco. The method comprises the following steps of after the materialfeeding of tobacco stems in the same batch, removing bent stems with the length being greater than 30mm; collecting the bent stems as a stem bending part; dividing the tobacco stems subjected to bentstem removal into four parts including stem slivers, fine stems, first thick stems and second thick stems; after the proportional compounding by orienting the reconstituted tobacco product demands, adding the materials into coating liquid of the reconstituted tobacco; and applying the product to the reconstituted tobacco. The classified processing is performed by aiming at the difference of the tobacco stems; the stem paste quality can be effectively regulated and controlled; the quality and the stability of the reconstituted tobacco between different batches can be improved; meanwhile, the processing process of the tobacco stems is optimized; and the utilization value of the tobacco stem raw materials is improved.

Description

technical field [0001] The invention relates to a screening and grouping method, in particular to a screening and grouping method for tobacco stem raw materials, and also relates to its application in reconstituted tobacco leaves, belonging to the field of reconstituted tobacco leaf processing. Background technique [0002] Compared with tobacco leaves, tobacco stems have heavier woody gas and low utilization value, but tobacco stems account for 20%-30% of the total tobacco leaves, and are the main by-products of the tobacco industry. The types of components are basically the same as those of tobacco leaves. slightly different. [0003] As one of the most important raw materials of reconstituted tobacco leaves, tobacco stem is not only one of the main sources of endogenous tobacco fiber, but also its extract is an important part of the reconstituted tobacco leaf coating liquid, so the quality of tobacco stems has a great influence on the quality of reconstituted tobacco leaf...
