Description

Technical Field

[0001] The utility model relates to the technical field of tobacco nicotine extraction, in particular to a tobacco nicotine extraction device. Background Technique

[0002] Nicotine is an organic compound with the chemical formula C10H14N2 and is highly toxic. It exists in solanaceous plants (Solanum) and is a representative of N-cholinergic receptor agonists. It has a paralyzing effect on both N1 and N2 receptors and the central nervous system and has no clinical application value. Nicotine has a relatively high content in tobacco plants and is one of the main alkaloids in tobacco. When smoking or using tobacco products, nicotine quickly enters the bloodstream through the lungs and then reaches the brain, which is one of the main reasons for smoking addiction. Nicotine can produce a series of physiological and psychological effects by stimulating the central nervous system, including refreshing, improving attention, enhancing mood, etc. However, due to its addiction, long-term use of tobacco products may lead to physical and mental health problems.

[0003] Extraction, also known as solvent extraction or liquid-liquid extraction, also called leaching, is a unit operation for separating mixtures by using the different solubilities of components in a solvent system. It is a method of transferring solute substances from one solvent to another by using the differences in solubility or partition coefficient of substances in two immiscible (or slightly miscible) solvents. It is widely used in industries such as chemistry, metallurgy, and food, and is commonly used in the petroleum refining industry. In addition, the operation of separating the two immiscible liquids after extraction is called liquid separation.
