Problems solved by technology

[0006] At present, cut stems are used in a certain proportion in low-end cigarette products, but are used in a very small amount in high-end cigarette products. On the one hand, it is not conducive to the reduction of the cost of high-end product leaf group formulations; Many high-end products have to adopt measures such as high-transparency disc paper and lengthened filter rods to reduce the amount of tar, which invisibly increases a lot of costs

Embodiment 1

[0023] The incoming tobacco stems (moisture content 12.5%) are quickly washed by the stem washing machine for 2 seconds to wash away the dust and silt on the surface of the tobacco stems. After the moisture content of the tobacco stems increases to 22%, enter the spiral ultrasonic stem washing machine for Deep stem washing, water temperature 20°C, solid-to-liquid ratio 1:20, washing time 1min, chloride ions, nitrates and some water-soluble substances in the tobacco stems are washed out, increasing the moisture content of the tobacco stems to 42%; The material centrifuge removes the moisture on the surface of the tobacco stems. While dehydrating, the moisture accelerates to penetrate into the interior of the tobacco stems and accelerates the softening of the tobacco stems; the dehydrated tobacco stems enter the vibrating fluidized bed and are dried to reduce the moisture to 28%. Then enter the shredded stem machine; cut the stems through the shredded stem machine; after the shre...

Embodiment 2

[0025] The incoming tobacco stems (moisture content 12.5%) are quickly washed by the stem washing machine for 8 seconds to wash away the dust and sediment on the surface of the tobacco stems, and after the moisture content of the tobacco stems increases to 26%, enter the spiral ultrasonic stem washing Machine for deep stem washing, water temperature 80°C, solid-to-liquid ratio 1:4, washing time 5min, chloride ions, nitrates and some water-soluble substances in the tobacco stems are washed out, so that the moisture content of the tobacco stems increases to 50%; The continuous discharge centrifuge removes the moisture on the surface of the tobacco stems. While dehydrating, the moisture accelerates to penetrate into the interior of the tobacco stems and accelerates the softening of the tobacco stems; the dehydrated tobacco stems enter the vibrating fluidized bed for drying to reduce the moisture to After 34%, it enters the stem cutting machine; the stems are cut by the stem cuttin...

Embodiment 3

[0027]The incoming tobacco stems (moisture content 12.5%) are quickly washed by the stem washing machine for 6 seconds to wash away the dust and sediment on the surface of the tobacco stems and increase the moisture content of the tobacco stems to 24%, then enter the spiral ultrasonic stem washing Machine for deep stem washing, water temperature 60°C, solid-to-liquid ratio 1:10, washing time 2min, chloride ions, nitrates and some water-soluble substances in the tobacco stems are washed out, so that the moisture content of the tobacco stems increases to 45%; Squeeze and extrude the tobacco stems with screw to remove moisture from the surface of the tobacco stems. While dehydrating, the moisture accelerates to permeate into the interior of the tobacco stems and accelerates the softening of the tobacco stems; the dehydrated tobacco stems enter the vibrating fluidized bed and are dried to make After the moisture drops to 30%, it enters the stem cutting machine; through the stem cut...

Abstract

The invention discloses a process for biochemically treating cut stems, which comprises working flows of stem washing, deep stem washing, surface dehydration of tobacco stems, stem baking, stem cutting, enzyme treatment, large-scale feeding and the like. The process, through deep stem washing, reduces the content of chloride ions and nitrate of the tobacco stems, improves the mouthfeel, and improves the safety; the process, through compound enzyme treatment, makes components which are not favorable for the taste in the tobacco stems reduced and components which are favorable for the taste increased so as to finally improve the inherent quality of the cut stems; and the process takes the processed cut stems as a carrier to add a natural tobacco extract to supplement the natural tobacco aroma, thereby improving the taste quality of the tobacco stems, and finally widening the using range of the cut stems.

Description

technical field [0001] The invention belongs to the technical field of shredded cigarettes, in particular to a technology for biochemical treatment of shredded stems. Background technique [0002] Cut stems are one of the important components in cigarette formula. Well-processed cut stems can not only increase the filling value of shredded tobacco, reduce the unit consumption of cigarettes, improve the combustibility of cigarettes and the permeability of smoke, but also reduce the Increase the amount of tar, improve the color and flavor of cigarettes. [0003] However, the quality of smoke produced by burning tobacco stems is obviously not as good as that of leaves, mainly manifested as insufficient aroma, bland smoke taste, less energy and greater irritation. According to the existing research results, the lack of aroma of shredded stems is due to the low content of some important components that affect the flavor of cigarettes, such as β-phenylethyl alcohol, β-domascenone...
