Problems solved by technology

However, in the current cut stem expansion technology, in order to ensure the expansion efficiency of the cut stems, the treatment intensity of the cut stems is relatively high. Although this ensures the expansion efficiency of the cut stems, it also causes a decline in the physical properties and sensory quality of the cut stems.

The method and application of the present invention have been described through preferred embodiments, and the relevant personnel can obviously make changes or appropriate changes and combinations to the method and application described herein without departing from the content, spirit and scope of the present invention to realize and Apply the technology of the present invention.

[0043] The reagents used in the present invention are all commercially available and can be purchased in the market.

[0044] The present invention adopts dried ...

Embodiment 1

[0046] The preparation of embodiment 1 cut stems for tobacco

[0047] Take a mixture of 1000kg of tobacco stems, wash the stems with warm water at 65°C, and store the stems in a closed air-conditioned cabinet at 27°C for 1 hour.

[0048] Carry out the first flash stem afterwards, make its moisture content be 32%, temperature is 60 ℃. Then, after the second storage of stems at 31°C for 1 hour in a closed air-conditioned cabinet, the second flash distillation makes the temperature ≥ 65°C.

[0049] Squeeze the stalks after the second flash evaporation, set the gap between the pressing rollers to ≤0.8mm, cut them vertically into shredded stalks with a width of 0.06mm, and store the stalks in the closed air-conditioned cabinet for 1.5h .

[0050] Then, the shredded silk is dried with a thin plate drum, the hot air temperature is 115°C, the cylinder wall temperature is 129°C, the outlet temperature is 52°C, the rotating speed is 36Hz, and the flow rate is 1900kg / h. Dry the shredd...

Embodiment 2

[0051] The preparation of embodiment 2 cut stems for tobacco

[0052] Take 1000kg of tobacco stem mixture, wash the stems with warm water at 60°C, and store the stems in a closed air-conditioned cabinet at 33°C for 65 hours for the first time.

[0053] Carry out first flash stem afterwards, make its moisture content be 31%, temperature is 65 ℃. Then, after the second storage of stems at 28°C for 65 hours in a closed air-conditioning cabinet, the second flash distillation makes the temperature ≥ 65°C.

[0054] Squeeze the stalks after the second flash evaporation, set the gap between the pressing rollers to ≤0.8mm, and cut them vertically into shredded stems with a width of 0.03mm.

[0055] Add CF-7011 produced by Yanbian Changbaishan Tianchi Daily Chemical Co., Ltd. to make its mass account for the mass percentage of crude cut stems and make its moisture content reach 38.5%, and the temperature reaches 48 °C, and store the stems in a closed air-conditioned cabinet for 1.5 hours...

Abstract

The invention relates to the field of a tobacco manufacturing technology, in particular to a cigarette cut stem preparation method and cigarette cut stem prepared by the method. The method comprises the steps of taking baked tobacco stem, washing the tobacco stem, storing the stem for a first time, carrying out flash evaporation on the stem for a first time, storing the stem for a second time, carrying out flash evaporation on the stem for a second time, pressing the stem and vertically cutting the stem to obtain a crude product of cut stem; taking the crude product of cut stem, storing the stem for a third time, drying the cut stem until the mass fraction of water in the cut stem is 13-14%, winnowing and storing the stem for a fourth time to obtain the cigarette cut stem. According to the method, the parameters such as temperature, rotating speed and the like are controlled, so that the fluffy effect of the cut stem can be improved, the surface of the cut stem contacted with the air flow is enlarged, the water is rapidly removed, the formation of condensate water is avoided, the loss of aroma substances in the cut stem can be reduced, and the packability and the sensory quality of the cigarette cut stem are improved. The experimental result proves that compared with the cut stem prepared by the traditional method, the cigarette cut stem prepared by the method provided by the invention has improved gloss, and is more sufficient in fragrance, less in offensive odor and stimulation and more comfortable in aftertaste.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to a method for preparing cut tobacco stems and the prepared cut tobacco stems. Background technique [0002] The tobacco stem is the main vein of the tobacco leaf and is an integral part of the tobacco leaf, accounting for about 25% of the tobacco leaf by weight. Shredded stems are thin filaments of a certain width made of dried tobacco stems after being shredded and expanded. amount released. Since cut stems are directly added to cigarettes, their quality directly affects the quality of cigarettes. Current cigarette companies are no longer solely pursuing their filling performance, but more importantly, the improvement of their quality. [0003] The test results showed that the chemical components of cut stems were quite different from those of cut leaves, and most of these chemical components would affect the smoking quality of cigarettes. For example: the contents ...
