Embodiment 1

[0031] The process for separating solanesol, tobacco extract and raffinate from waste tobacco leaves, the process steps are:

[0032] 1. Use waste tobacco leaves as raw materials, the moisture content of which is about 18%, and the tobacco stem content is about 33%; the stem leaves are separated by manual methods, the long stems are used as cigarette raw materials, and the short stems are used as paper-making tobacco sheets For the production of raw materials, the leaves are mechanically crushed into tobacco leaf fragments with a maximum size of 0.5-3mm; the tobacco leaf fragments are then dedusted, dried and dehydrated by vibrating airflow drying equipment, so that the moisture content of the tobacco leaf fragments reaches a mass ratio of less than Equal to 5%. At this time, the content of solanesol in the raw material is about 0.7%.

[0033]2. Using an aqueous methanol solution with a concentration greater than or equal to 70% as a solvent, place the tobacco leaf fragments ...

Embodiment 2

[0042] The technology for separating solanesol, tobacco extract and raffinate from waste tobacco leaves is based on Example 1. In the column adsorption process of its process step 7, different adsorbents are used to adsorb and separate tobacco. Components such as tobacco sugar alcohol, nicotine, nitrate and chloride in the aqueous extract solution make the tobacco extract obtained in the process step 8 a low-harm adjustable product. The so-called low-harm adjustable refers to the separation of certain components in waste tobacco leaves that are harmful to the human body or unfavorable to production when they exceed the standard. When the production process of cigarettes or paper-making tobacco sheets requires certain separated components Only added back as required. Tobacco extract can improve its product function and applicability by becoming a low-harm adjustable product.

Embodiment 3

[0044] The technology for separating solanesol, tobacco extract and raffinate from waste tobacco leaves is based on embodiment one or two, after it completes process step 9, use the raffinate obtained by process step 9, The short stem obtained in process step 1 and the tobacco extract obtained in process step 8 are directly made into paper-making tobacco sheets, and the process steps are:

[0045] 10. Using water as a solvent, put the raffinate and short stems in water according to the solid-liquid mass ratio of 1:15, and divide them into three extractions. The extraction temperature is about 90°C, and the total extraction time is about 1.5 hours; the extraction process is carried out by means of Mechanical agitation and liquid reflux circulation are used to increase the extraction rate, and the liquid reflux is controlled at 2000 kg / hour.

[0046] 11. Collect the raffinate and the extract of the short stem, and then send it to the vacuum distillation equipment to concentrate ...

Abstract

The invention relates to a process of separating solanesol, tobacco extract and extract leavings from waste tobacco leaf. The invention is to solve problems of wasting large part of material, low extracting rate of solanesol anf product quality, high production cost and environmental pollution. The process comprises following steps: separating stalk and leaf; disintegrating leaves; removing impurities and drying; extracting dissolvent; getting extract and leaving; condensing the extract and getting a part of solanesol; separating the extract with column again and getting another part of solanesol and tobacco extract. The process is characterized in that the dissolvent is methanol solution with its concentration being equal to or larger than 70%. The tobacco stalk, scent-emitting material and tobacco fiber can be directly used to prepare tobacco slice.

Description

technical field [0001] The invention belongs to a tobacco product preparation process, in particular a process for extracting and separating solanesol, tobacco extract and raffinate from waste tobacco leaves that cannot be used for cigarette products. Background technique [0002] As we all know, in the process of tobacco planting and purchasing for cigarettes, about 200,000 tons of waste tobacco leaves are produced nationwide every year (about 1.7 million tons of tobacco leaves are planted in the country every year, and waste tobacco leaves account for about 13%) as waste treatment and cannot be produced by cigarettes. use. The waste tobacco leaves generally come from four aspects: one is the tobacco leaves that normally grow on the top and bottom of the tobacco plant; the other is the tobacco leaf fragments with the largest size less than 5 mm produced during the processing of the cigarette redrying factory; the third is the tobacco leaves that occur during storage and tra...
