Problems solved by technology

However, the tobacco extract is a buffer solution system in which a variety of acid-base balances and precipitation-dissolution balances coexist. During the process of adjusting the tobacco extract to alkalinity, some precipitation will occur due to the shift of the balance. During the concentration process, it will cause fouling problems in the concentrator
[0004] Potassium and sodium salts of organic acids are good combustion accelerants for tobacco products. They not only have the effect of reducing coke, but also improve the sensory quality of tobacco products. However, it was found during the preparation of the coating liquid that organic acid salts were directly added to the tobacco concentrate It will lead to a large amount of precipitation, which will lead to high viscosity of the coating liquid, which is not conducive to the absorption of the substrate during the coating process, and the dried sheet is prone to problems such as stickiness and agglomeration

preparation example Construction

[0037] The invention provides a method for preparing a coating solution for reconstituted tobacco leaves. The method is suitable for preparing a low-nicotine and low-viscosity coating solution in the process of papermaking reconstituted tobacco leaves.

[0038] The preparation process of the reconstituted tobacco leaf coating liquid in this application comprises the following steps:

[0039] 1) extracting the tobacco raw material with water, and separating the solid and liquid to obtain the tobacco extract.

[0040] Specifically, the tobacco raw materials are tobacco stems, tobacco sheets and tobacco powder, and the three raw materials are mixed according to the mass ratio of (4-8): (1-4): (1-4), and then the total weight of the raw materials is added 4-7 times of water, soak and extract at 40-80°C for 30-60 minutes, and then separate solid-liquid to obtain tobacco insoluble matter and tobacco extract.

[0041] 2) Adding a strong base to the tobacco extract to obtain an alkal...

Embodiment 1

[0050] 1) After the tobacco raw material is extracted with an extractant, solid-liquid separation is obtained to obtain tobacco insoluble matter and tobacco extract. The tobacco raw material is tobacco stem, tobacco sheet and tobacco dust, and the mass ratio of tobacco stem, tobacco sheet and tobacco dust is 5: 3:2, the extraction agent is water, the amount of water is 5 times the total weight of tobacco raw materials, the extraction temperature is 70°C, and the extraction time is 30 minutes;

[0051] 2) adding potassium hydroxide to the tobacco extract obtained in step 1), controlling the weight ratio of potassium hydroxide and tobacco extract to be 0.6:100 to obtain an alkaline extract;

[0052]3) Centrifuge the alkaline extract that step 2) obtains with a centrifuge, the centrifuge speed is 3000r / min, and the centrifugal time is 5min to obtain a refined extract;

[0053] 4) concentrating the refined extract obtained in step 3) under reduced pressure, the concentration tempe...

Embodiment 2

[0056] 1) After the tobacco raw material is extracted with an extractant, solid-liquid separation is obtained to obtain tobacco insoluble matter and tobacco extract. The tobacco raw material is tobacco stem, tobacco sheet and tobacco dust, and the mass ratio of tobacco stem, tobacco sheet and tobacco dust is 5: 3:2, the extraction agent is water, the amount of water is 5 times the total weight of tobacco raw materials, the extraction temperature is 70°C, and the extraction time is 30 minutes;

[0057] 2) adding potassium hydroxide to the tobacco extract obtained in step 1), controlling the weight ratio of potassium hydroxide and tobacco extract to be 0.8:100 to obtain an alkaline extract;

[0058] 3) centrifuge centrifugal purification step 2) to obtain the alkaline extract, the centrifuge speed is 4000r / min, and the centrifugation time is 5min to obtain a refined extract;

[0059] 4) concentrating the refined extract obtained in step 3) under reduced pressure, the concentrati...

Abstract

The invention provides reconstituted tobacco coating liquid and a preparation method of the reconstituted tobacco coating liquid. The preparation method comprises the following steps: extracting a tobacco raw material with water, and carrying out solid-liquid separation to obtain tobacco extracting liquid; adding strong base into the tobacco extracting solution, thus obtaining an alkaline extracting solution; centrifugally purifying the alkaline extracting solution to obtain a refined extracting solution; concentrating the refined extracting solution under reduced pressure to obtain a tobaccoconcentrated solution; and adding tobacco essence and organic acid into the tobacco concentrated solution to obtain the tobacco coating liquid. According to the technical scheme, the operation is simple, the cost is low, and large-scale production can be easily realized.

Description

technical field [0001] The invention relates to the technical field of reconstituted tobacco leaves, in particular to a coating liquid for reconstituted tobacco leaves. Background technique [0002] Reconstituted tobacco leaf, also known as tobacco flakes, is an important form of tobacco waste reuse and has great environmental protection and economic value. Its production technologies mainly include rolling method, thick pulp method, and papermaking method. The typical production process of reconstituted tobacco leaves by papermaking method is to extract tobacco raw materials with water and separate solid and liquid to obtain tobacco extract and tobacco insoluble matter. The tobacco base sheet is made by pulping and papermaking, and then the coating solution and the tobacco base sheet are recombined by dip coating or spraying, and finally dried and cut to obtain the finished product. Due to the absorption of the technical characteristics of pulping, papermaking and paper pr...
