Problems solved by technology

[0003] The extraction process of phytin in corn steep liquor, peanut shell, bran, distiller's grains and rice bran has been reported at home and abroad. The corresponding extraction methods include acid extraction, alkali neutralization, ion exchange, macroporous resin elution, microwave-assisted and ultrasonic acid leaching extraction etc.; the above method has certain applicability, but there are also many problems, which limit the extraction and utilization of phytin. Simple and easy to operate, but 6-7 tons of sewage is required to process 1 ton of raw materials, and the amount of wastewater discharged per ton of Phytin produced is as high as 60-70 tons, and the environmental pollution is relatively serious; ② The ion exchange method (CN 102702250 A) is used Ion exchange column adsorbs phytic acid in corn steep liquor, then washes it with acid, neutralizes it with lime water to pH 4.0-6.0, precipitates, dries, and pulverizes to obtain phytin
This method is simple to operate, but the output is low, and the acid elution will cause great damage to the ion exchange material, and the resin material needs to be replaced at any time, which increases the production cost
Microwave extraction (CN200710170689.2) can shorten production time, reduce energy and solvent consumption, but microwave extraction requires high technological conditions, the extraction process is cumbersome, and cannot be scaled up for pilot testing; ③Ultrasonic extraction can increase the leaching rate, Save energy and avoid the influence of high temperature on the extracted components, but the ultrasonic generator has high manufacturing cost and is easy to be damaged, so it is not suitable for large-scale industrial production

Abstract

The invention discloses an extraction method for co-producing nicotine by extracting inositol hexaphosphate calcium magnesium from tobacco waste. The method takes tobacco roots, leaves, stalks or fireworks, pulverizes them, and extracts nicotine first under slightly acidic conditions. , and under this condition, phytic acid cannot be freed. Continue to adjust the pH to 2.0-3.0 to extract phytic acid and further generate inositol calcium magnesium hexaphosphate. The biggest advantage of this process is that it can be produced simultaneously by continuously adjusting the pH value. Inositol calcium magnesium hexaphosphate and nicotine reduce production costs; this process has high extraction efficiency, can simultaneously obtain phytin and nicotine, greatly reduces sewage discharge, reduces production costs, and is more practical for making full use of tobacco waste resources meaning.

Description

technical field [0001] The invention relates to an extraction process for extracting inositol hexaphosphate calcium magnesium and co-producing nicotine from tobacco waste. Background technique [0002] my country has a large tobacco planting area, and a certain amount of tobacco leaves cannot be used for cigarette production during the harvesting process. At the same time, a lot of waste such as stalks, roots and fireworks are left behind. It is a pity to discard them if they cannot be used. Tobacco waste contains a variety of chemical components, mainly including alkaloids, proteins, amino acids, glycosides, sugars, organic acids and other substances. Among them, nicotine, solanesol, organic acid, tobacco protein, etc. all have high utilization value. The comprehensive utilization of waste tobacco leaves has always been valued by researchers at home and abroad, and many relatively mature extraction processes and methods have been produced. There are mainly the following th...
