Problems solved by technology

[0005] But so far, the existing technology mainly adopts supercritical fluid to directly extract tobacco raw materials. Due to the large volume of tobacco and small bulk density, the processing capacity of each extraction is very small, and the yield is correspondingly low. Equipment investment larger
In addition, due to the use of pure supercritical fluid, no carrier is involved, so that the range of objects extracted by supercritical fluid is relatively small, mainly limited to high volatility and low polarity compounds, but it can also flavor many cigarettes contained in tobacco The low-volatility aromatic substances that play a key role cannot be extracted

Embodiment 1

[0025] Take oriental tobacco extract and glass ball filler and mix evenly, the weight ratio of tobacco extract and glass ball is 1:6, then put it into the extraction tank, feed carbon dioxide gas, pressurize the high-pressure pump to 10 MPa, and the temperature is 35 °C , the separation pressure is 4 MPa, the separation temperature is 40° C., the extraction is carried out for 30 minutes, and the degreasing is carried out. Then the composition of the supercritical fluid is changed, and the ethanol with a volume ratio of 2% is injected by the entrainer pump as the entrainer. The entrainer ethanol must first be added to the mixing tank and mixed with carbon dioxide, and then preheated at 50 ° C through the preheating tank. Enter the extraction tank for circular extraction, the extraction pressure is 38 MPa, and the temperature is 50°C. After 90 minutes, the tobacco absolute was drained from the separator. The product is clear in appearance and has the characteristic aroma of ori...

Embodiment 2

[0027] Except that the chemical filler is a Raschig ring, and the weight ratio of the tobacco extract and the Raschig ring is 1:9, other processes are the same as in Example 1.

Embodiment 3

[0029] Except that the chemical filler is a saddle ring, and the weight ratio of the tobacco extract and the saddle ring is 1:6, other processes are the same as in Example 1.

Abstract

A process for preparing pure tobacco oil includes mixing tobacco extract with magnetic chemical filler, mixing one of alcohol, acetone and water, preheating, extracting lipids substance from tobacco extract with supercritical fluid, cyclically, and separating pure tobacco oil.

Description

technical field [0001] The present invention relates to a preparation method of tobacco absolute, more specifically, the present invention relates to a method for extracting tobacco absolute from tobacco extract by means of supercritical fluid extraction technology. Background technique [0002] Tobacco flavoring and additives have become an indispensable and increasingly important technology in contemporary cigarette production. In cigarette production, flavoring and additives are used to enrich the aroma substances and sweeteners in products to improve the aroma of smoke. , Improve the physical shape and taste of shredded tobacco, so that the smoking quality of cigarette products will be more perfect and perfect. At present, with the development of the anti-smoking campaign, the development of low-tar cigarettes has become the direction of the survival and development of the tobacco industry. In order to compensate for the smell of smoke, in additio...
