PROCESS FOR IMPROVING TOBACCO MATERIALS AND DEVICE THEREOF

摘要

Disclosed is a process and an apparatus for improving tobacco raw material. The invention aims to solve the problems of complexity, high costs of manufacturing and the safety problems rendered by additive non-tobacco substances which affect traditional tobacco smoke flavor and cause environmental contamination in the conventional improvement technologies. The process mainly comprises performing an extraction from at least one of tobacco leafs, tobacco flakes, tobacco powder, stalks and cut stems by mixed solvents, conducting a solid-liquid separation for the tobacco raw material, applying the extract liquor of tobacco leaves, flakes and cuts for manufacturing tobacco extract and that of stalks and cut stems for manufacturing fertilizer, diluting and mixing a given amount of tobacco aqueous extract and ethanol extract and removing harmful components so as to get feed liquid, backfilling the feed liquid to the tobacco raw material, and drying the tobacco raw material to a certain dryness to obtain the products. The apparatus is a system composed of a plurality of interconnected independent devices such as extractor, solid-liquid separator, a feed liquid backfiller, etc.
