Problems solved by technology
At present, sulfuric acid is commonly used to neutralize the secondary extraction of nicotine. Add sulfuric acid and extract to an ordinary container for manual or machine stirring to complete the extraction. When the organic solvent comes into contact with sulfuric acid, impurities, bubbles and serious The turbulent flow is prone to emulsification, resulting in high scrap rate and continuous production
At present, there is no good equipment for efficient extraction of nicotine extract in China

The invention relates to the technical field of preparation of nicotine, in particular to a centrifugal extracting device for nicotine. The centrifugal extracting device for nicotine comprises a box, wherein a partition is mounted in the box; a rotating barrel is mounted in the partition; a weir section is mounted on the top of the inside of the rotating barrel; a light-phase weir is arranged at the bottom of the weir section; a heavy-phase weir is arranged on one side of the weir section; the light-phase weir is connected with a light-phase outlet through a light-phase channel; the heavy-phase weir is connected with a heavy-phase outlet through a heavy-phase channel; a motor is mounted on the top of the box; an output end of the bottom of the motor is connected with a rotating shaft; a plurality of supports are mounted at the bottom of the inside of the box body; a connecting plate is arranged between the supports; a hydraulic cylinder is mounted on the connecting plate; the top of a piston of the hydraulic cylinder penetrates through the box body and is connected with a connecting rod through a bearing; and stirring blades are mounted in the middle of the connecting rod. The invention further provides a centrifugal extracting method for nicotine. According to the device, the nicotine is extracted by a low-concentration alkaline solution, corrosion to the device is prevented, meanwhile, extracting is implemented by a centrifugal manner, the extracting efficiency is high, and the capacity is improved favorably.
Description
technical field [0001] The invention relates to the technical field of nicotine production, in particular to a nicotine centrifugal extraction device and method. Background technique [0002] Tobacco contains a variety of alkaloids, among which more than 40 have been identified, among which nicotine has the most content, accounting for about 95% of tobacco alkaloids, and nicotine accounts for 0.5-6% of tobacco dry weight. Nicotine is widely used in the field of medicine and chemical industry. Pharmacological studies have shown that nicotine can combine with nicotinic choline in the peripheral and central nervous systems, have multiple effects on the brain, activate various neurochemical channels, and the effects on the central nervous system can lead to improved wakefulness, attention and response Sexuality, reducing anxiety and stress reactions. At present, sulfuric acid is commonly used to neutralize the secondary extraction of nicotine. Add sulfuric acid and extract to ...
