Embodiment 1

[0037] The tobacco stem processing method of this embodiment includes the following steps:

[0038] 1) Prepare an aqueous solution of ammonium carbonate with a mass percentage of 10%, and spray the aqueous solution of ammonium carbonate evenly on the stems according to the ratio of the mass ratio of the aqueous ammonium carbonate to the tobacco stems of 15:100, and mix them to obtain a mixture;

[0039] 2) Heat the resulting mixture at 40°C for 3 hours, and then use a twin-screw extruder for extrusion and expansion, and quickly cool the extruded material from the twin-screw extruder to room temperature to obtain an expanded material; During the treatment, the screw speed of the twin-screw expansion agent was 2r / s, and the extrusion treatment temperature was 150°C.

[0040] The puffed tobacco stems obtained by the method for treating tobacco stems of this embodiment are refluxed for 3 hours with a 50% (volume) ethanol aqueous solution, and the solvent is evaporated after solid-liquid ...

Embodiment 2

[0042] The tobacco stem processing method of this embodiment includes the following steps:

[0043] 1) Prepare a mixed aqueous solution of ammonium acetate and ammonium sulfate with a mass percentage of 20%; the mass ratio of ammonium acetate to ammonium sulfate in the mixed aqueous solution is 1:3, and the mass ratio of the mixed aqueous solution to the tobacco stem is 20:100. The mixed aqueous solution is evenly sprayed on the tobacco stems and mixed to obtain a mixture;

[0044] 2) Heat the resulting mixture at 50°C for 1 hour, and then use a twin-screw extruder for extrusion processing, and quickly cool the extruded material from the twin-screw extruder to room temperature to obtain an expanded material; During the treatment, the screw speed of the twin-screw expansion agent was 8r / s, and the extrusion treatment temperature was 100°C.

Abstract

The invention relates to a treatment method for tobacco stems and a preparing method for a tobacco stem extract, and belongs to the technical field of tobacco. The treatment method for the tobacco stems comprises the following steps of uniformly spraying an aqueous ammonium salt solution to the tobacco stems to obtain a mixed material; then squeezing and extruding the mixed material. The treatmentmethod for the tobacco stems is suitable for pretreatment of the tobacco stems before preparation of the tobacco stem extract. According to the treatment method and the preparing method, the treatment process is simple, the equipment cost is low, amplification and continuous production are facilitated, the efficiency of extracting the tobacco stems can be obviously improved, the content of macromolecule matter of the tobacco stem extract is lowered, and the fragrance of the tobacco stem extract is improved.

Description

Technical field [0001] The invention relates to a method for processing tobacco stems and a method for preparing tobacco stem extracts, and belongs to the technical field of tobacco. Background technique [0002] Tobacco stems are the thick, hard veins of tobacco leaves, accounting for about 25-30% of the total weight of tobacco leaves. Millions of tons of tobacco stems are produced nationwide each year, which are mainly used to prepare tobacco flakes and expanded stems. Tobacco flakes and shreds made from tobacco stems have a weak aroma, heavy odor and woody air, and high irritation when they are smoked. The amount in cigarettes is very limited, and the utilization rate of tobacco stems is still relatively low. The stem was abandoned, causing environmental pollution and waste of resources. Tobacco stems have similar chemical components to tobacco leaves, and the preparation of tobacco extracts from tobacco stems is an important way to utilize waste tobacco stems. [0003] Compa...
