Method for reducing loss of fragrant substances of reconstructed tobaccos in concentration process

Abstract

The invention relates to a method for reducing the loss of fragrant substances of reconstructed tobaccos in the concentration process. The method comprises the following steps of: concentrating a tobacco water extracting solution obtained by an extraction working section in the process of producing the reconstructed tobaccos by a papermaking method; mixing polyhydric alcohol and the tobacco water extracting solution in a weight ratio of 1:10-1:100 uniformly in a concentration working section, and adding the mixture into concentration equipment; and concentrating at concentration temperature of between 45 and 100 DEG C under the concentration condition that the vacuum degree is 0.04 to 0.08 MPa until tobacco paste of which the density is 1.220+ / -0.005 is obtained. By the method, the quality of coating liquid can be improved effectively, so that the quality of the reconstructed tobaccos is improved, and tobacco discarded raw materials can be utilized fully and reasonably.

Description

technical field [0001] The invention relates to the technical field of manufacturing reconstituted tobacco leaves in the tobacco industry. Background technique [0002] Paper-making method reconstituted tobacco is made from waste tobacco raw materials of cigarette products through extraction, pulping, base paper making, coating, drying, cutting and other processes. In the tide of tobacco control in today's society, the production of low-tar and low-hazard cigarette products has become the consensus of cigarette manufacturers. Paper-making reconstituted tobacco has received extensive attention because of its high filling degree and tar-reducing function. It is widely used in cigarette formulations. However, the processing technology of reconstituted tobacco leaves will cause the loss of aroma substances, which has a negative impact on the quality of reconstituted tobacco leaf products and cigarette products. Therefore, the aroma compensation technology at the same time as r...

AI Technical Summary

Problems solved by technology

Generally speaking, in the extraction process of reconstituted tobacco leaves, these aroma substances will more or less enter the tobacco water extract. Among these components, alkaloids, alcohols, aldehydes, ketones and some heterocyclic compounds belong to low boiling point Substances will cause a lot of loss in the process of decompression and concentration. According to the different production equipment and processes of various enterprises, this loss is about 30% to 50%, and these aroma substances are an important source of tobacco aroma. The loss seriously restricts the quality improvement of papermaking reconstituted tobacco products

Although various companies try their best to make up for it by adding flavors and spices in the follow-up process, they cannot solve the problem from the root.
