Pretreatment method of tobacco stalk raw material

Abstract

The invention discloses a pretreatment method of tobacco stalk raw material, comprising the following steps: firstly, dissolving 0.1-30 parts of ammonium salt into 10-100 parts of water according to weight parts, mixing and dissolving the ammonium salt to prepare ammonium salt solution for stand-by application; then, smashing quicklime and screening the smashed quicklime through a 40 mesh screen, and then, preparing the quicklime powder whose diameter is smaller than 40 mesh for stand-by application; spraying the ammonium salt solution to the tobacco stalk of 100-1000 parts and mixing them to lead the tobacco stalk to be fully absorbed; lastly, evenly mixing the 0.1-10 parts of quicklime powder and the tobacco stalk which is processed through ammonium salt solution, and stacking and storing the tobacco stalk for 20-40 days. The invention can complete the pretreatment of the tobacco stalk during the storing course of the tobacco stalk, can not affect the re-using of the production process time for the tobacco stalk; meanwhile, the pretreatment of large quantities of raw materials can be simultaneously conducted, therefore, the invention not only can improve the physical and chemical structure of the tobacco stalk, but also can effectively increase the internal quality of the tobacco stalk.

Description

technical field [0001] The invention belongs to the field of tobacco raw material processing, in particular to a chemical pretreatment method for tobacco stems during storage. Background technique [0002] Tobacco stem belongs to the product of raw tobacco in the process of threshing and redrying, and its content in raw tobacco is about 25-30%. Its utilization rate in cigarette industry raw materials directly affects the reduction of cigarette formula cost. In view of the characteristics of tobacco stem itself-the main chemical components are quite different from tobacco leaves in content, mainly for the low content of total nitrogen and nicotine, slightly low reducing sugar, so the sugar-base ratio is high; cellulose, hemicellulose , pectin and lignin content are significantly higher than tobacco content, and these structural characteristics such as weak aroma affect its use value in cigarette industry raw materials. In response to this situation, the current chemical pret...

Problems solved by technology

In response to this situation, most of the current chemical pretreatment methods for tobacco stems are completed during the production process of tobacco stems that meet the raw material conditions of the tobacco industry. Ammonium salts and alkaline substances are used to improve the quality of tobacco stems, but one of the limitations of this method is limited treatment capacity, high treatment temperature, and high energy consumption; the second limitation is that the treatment process occurs during the production process On the one hand, it will lengthen the production process time of the product, on the other hand, it will also cause the quality fluctuation range of different batches of raw materials processed at different times and other responsible factors; and the pretreatment method in the storage period of tobacco stems is currently mostly artificial fermentation Or enzyme treatment, the limitation of this treatment method is: in order to ensure the biological activity of the enzyme, the environmental temperature and humidity must be controlled within a certain range, and the treatment conditions are relatively harsh, resulting in high treatment costs or difficult control of treatment results.
