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 the oriental tobacco extract and the glass ball filler and mix it evenly. The weight ratio of the tobacco extract to the glass ball is 1:6, and then put it into the extraction tank, introduce carbon dioxide gas, and pressurize the high pressure pump to 10 MPa, the temperature is 35 ℃ , Separation pressure 4 MPa, separation temperature 40 ℃, extraction for 30 minutes, degreasing. Then change the composition of the supercritical fluid, and use the entrainer pump to pump in ethanol with a volume ratio of 2% as the entrainer. The entrainer ethanol must be added to the mixing tank and mixed with carbon dioxide first, and then preheated at 50°C in the preheating tank. Enter the extraction tank for cyclic extraction, the extraction pressure is 38 MPa, and the temperature is 50°C. After 90 minutes, the absolute tobacco oil was discharged from the separator. The product has a clear appearance, has the characteristic aroma of oriental tobacco, and has good solubility in common s...

Embodiment 2

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

Embodiment 3

[0029] Except that the chemical filler is a rectangular saddle ring, and the weight ratio of the tobacco extract to the rectangular saddle ring is 1:6, the 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 method for preparing tobacco absolute oil, more specifically, the present invention relates to a method for extracting tobacco absolute oil from tobacco extract using supercritical fluid extraction technology. Background technique [0002] Tobacco flavoring additives have become an indispensable technology in contemporary cigarette production, and it is increasingly showing its importance. In cigarette production, flavoring additives are used to enrich the aroma substances and sweeteners in the products to improve the flavor of smoke. , Improve the physical shape and smoking taste of shredded tobacco, thereby making the smoking quality of cigarette products 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 survival and development of the tobacco industry. In order to compensate for the smell of s...
