Problems solved by technology

my country's Henan, Hunan, Guangdong, Fujian, Yunnan, Guizhou and other provinces have a large area of ​​tobacco fields, and many cigarette factories and re-cured tobacco leaf factories have a large amount of waste tobacco leaves, soot, and tobacco rods every year. If they are not well utilized, they are burned by a fire. This treatment not only wastes resources, but also causes environmental pollution. How to make reasonable and comprehensive utilization of these tobacco wastes is an urgent issue in front of people.

Embodiment 1

[0044] Example 1 Preparation of Ultrasonic Pretreatment Solution

[0045] Method 1: Grind 100g of dried tobacco material into a particle size of 20 meshes, add an aqueous medium equivalent to 10 times the volume of the tobacco material, adjust the pH value to 11, and perform ultrasonic pretreatment. The ultrasonic power is 20kHz. The time is 20 minutes, and the ultrasonic pretreatment solution 1 is obtained.

[0046] Method 2: crush 100g of dried tobacco material into a particle size of 40 meshes, add an aqueous medium equivalent to 30 times the volume of the tobacco material, adjust the pH value to 13, and perform ultrasonic pretreatment, the ultrasonic power is not less than 40kHz, The pretreatment time is 40 minutes, and the ultrasonic pretreatment solution 2 is obtained.

[0047] Method 3: crush 100g of dried tobacco material into a particle size of 40 mesh, add an aqueous medium equivalent to 30 times the volume of the tobacco material, adjust the pH value to 9, and per...

Embodiment 2

[0048] Example 2 Preparation of Nicotine

[0049] The preparation of nicotine is divided into six groups. The first group uses the ultrasonic pretreatment liquid 1 prepared in Example 1 as a raw material to extract nicotine; the second group uses the ultrasonic pretreatment liquid 2 prepared in Example 2 as a raw material to extract nicotine. Alkaline extraction; the third group uses the ultrasonic pretreatment solution 3 prepared in Example 3 as the raw material to extract nicotine; the fourth group of raw materials is compared with the second group, the difference is that the pretreatment obtained after no ultrasonic pretreatment Liquid 4; the raw material of the fifth group is compared with the second group, the difference is that the ultrasonic pretreatment liquid 5 obtained at a pH value of 8.5 is the raw material for the extraction of nicotine; the raw material of the sixth group is compared with the second group, the difference is that The ultrasonic pretreatment solu...

Embodiment 3

[0053] Example 3 Preparation of hemicellulose

[0054] The preparation of hemicellulose is divided into three groups. The first group uses the ultrasonic pretreatment solution 1 prepared in Example 1 as a raw material to extract hemicellulose; the second group uses the ultrasonic pretreatment solution 2 prepared in Example 2 as a raw material. Carry out the extraction of hemicellulose; the raw material of the third group is compared with the second group, the difference lies in the pretreatment liquid obtained after not carrying out ultrasonic pretreatment.

[0055] The method for extracting hemicellulose in this example is as follows: filter the ultrasonic pretreatment solution or pretreatment solution to obtain a filtrate, adjust the pH value of the filtrate to 3.0, and perform liquid-solid separation after the solid precipitation is completely produced. The solid precipitated as hemicellulose.

[0056] Among them, the first group of hemicellulose is 10.6g, the yield is 8...

Abstract

The invention relates to the technical field of crop deep processing, in particular to a novel method for continuously extracting nicotine, hemicellulose, lignin and cellulose from tobacco by utilizing ultrasonic alkalization pretreatment. The continuous extracting method comprises the following steps of: grinding the tobacco into powder with particle size of not less than 20 meshes; adding a water medium of which the volume is equivalent to 10 to 30 times of the volume of the tobacco; regulating a pH value to the range of 9 to 13; carrying out ultrasonic pretreatment to obtain ultrasonic pretreatment solution, wherein the ultrasonic power is not lower than 20kHz and the ultrasonic pretreatment time is not shorter than 20 minutes; and then further extracting nicotine, hemicellulose, lignin and cellulose. By the continuous extracting method, useful substances in the tobacco can be furthest utilized; not only is the aim of waste utilization fulfilled, but also a novel path is developed for a tobacco production process; and the reference is provided for comprehensive utilization of the tobacco.

Description

Technical field [0001] The present invention involves the field of crop deep processing technology, and specially involves a new method of continuously extraction of nicotin, semi -cellulose, lignin, and cellulose from tobacco. Background technique [0002] my country is a large country of tobacco production. It not only produces a large amount of tobacco waste, tobacco, pollution, or mildew tobacco leaves during the storage and transportation and cigarette production of tobacco leaves and cigarette production. The number is also considerable.Tobacco leaf contains a variety of chemical composition with valuable value. If it is comprehensively utilized, it will not only improve the pollution of waste to the environment, but also create wealth for the country.However, due to the backward process conditions and high product costs, the market competitiveness is not high and the comprehensive utilization efficiency is the situation of Tobacco.Mao, produced in South America L'L. It is ...
