Embodiment 1

[0019] Embodiment one is the processing step of the present invention:

[0020] (1) Get 100 kilograms of shredded stem material, enter the extractor for downstream extraction, the ratio of material to solvent is 1:20, the time is 60 minutes, and the solvent temperature is 50°C;

[0021] (2) The extracted shredded stems are separated from solid and liquid by a juicer;

[0022] (3) After separation, the shredded stems are extracted twice with a conversion tank, the ratio of material to solvent is 1:15, the time is 30 minutes, and the solvent temperature is 50°C;

[0023] (4) utilize centrifuge solid-liquid separation;

[0024] (5) Backfilling with the cut stem feed liquid after centrifugation, the concentration of the feed liquid is 40%, and the backfill rate is 60%;

[0025] (6) After backfilling, the cut stem moisture is 55%, and moisture pretreatment is carried out;

[0026] (7) drying and puffing again to obtain the finished cut stem with a moisture content of 12%.

Embodiment 1

[0027] The experimental data of embodiment one are as follows:

[0028] (1) After the centrifuge comes out, take 5 stem samples to test the dryness, the data are as follows:

[0029] sample

[0030] (2) Bake 5 samples uniformly to a moisture content of 12%, and detect the crushing condition, the data are as follows:

[0031] sample

[0032] (3) Take 100 grams of each of the 5 samples, soak them for the second time with 1:20 clean water, extract for 2 hours, and compare the extraction rate with that of the centrifuge. The data are as follows:

[0033] sample

[0034] 3#

[0035] (4) Routine chemical testing of finished cut stems:

[0036] Nicotine (%)

[0037] The test samples were made into sample cigarettes for smoking evaluation, and the smoking evaluation results: slightly better aroma, moderate concentration, light woody smell, slight miscellaneous smell, less irritating, and more comfortable aftertaste.

Abstract

The invention relates to the technical field of consumer tobacco, in particular to a dewatering method in the process of cut tobacco stem reconstitution, which includes: extracting, solid-liquid separation, refilling, cut stem drying and cut stem expanding. The dewatering method is characterized by including the steps: firstly, cutting stems; secondly, sending the cut stem into a continuous extracting device; thirdly, subjecting the extracted cut stem to solid-liquid separation by a press; fourthly, subjecting the separated cut stem to secondary extraction by a conversion canister; fifthly, using a centrifuge for solid-liquid separation; sixthly, subjecting the separated cut stem to liquor refilling by spraying; seventhly, subjecting the cut stem, which contains 60-70% of water and subjected to liquor refilling, to water pretreatment so that the water content drops to 35%; and eighthly, drying and expanding to obtain finished cut stem which contains 13%+ / -1 of water. Compared with theprior art, the method is high in extracting rate, internal quality of the cut stem is improved, harmful ingredients of the cut stem are reduced, dryness of the cut stem subjected to solid-liquid separation by the centrifuge is high, and difficulty and energy consumption in post-drying are decreased.

Description

[technical field] [0001] The invention relates to the technical field of consumer goods tobacco, in particular to a dehydration method in the process of tobacco reconstituted shredded stems. [Background technique] [0002] The traditional dehydration process includes downstream extraction, solid-liquid separation, backfilling, dried stems and puffing until the moisture content of the cut stems is 13%. The specific steps are: (1) cut the stem so that the thickness of the shredded stem is 0.12-0.18mm; (2) enter the continuous extraction device, and extract the material with a solvent ratio of 1:20; (3) extract the shredded stem with a juicer For solid-liquid separation, the frequency is set at 10-15 Hz; (4) After separation, the shredded stems are backfilled with the feed liquid, using a spraying method; The treated moisture is reduced to 35%; (6) drying and puffing, and the moisture content of the finished cut stems is 13%±1. [0003] The traditional cut stem dehydration sy...
