Problems solved by technology

But many inherent modes cannot be applied to solid-state fermentation of tobacco stems
For example, the water immersion operation of fermented raw materials is generally to soak the raw materials in water to make the raw materials fully absorb water, but this is not suitable for tobacco stem materials, because the water absorption of tobacco stems is very strong, even if the ratio of water to material is 10:1, the raw materials in the raw materials There is also no free water, but such a water content is not conducive to the solid state fermentation of tobacco stems

Abstract

The invention relates to the technical field of tobacco processing, and discloses a new system suitable for solid-state fermentation of tobacco stems and a corresponding solid-state tobacco stem fermentation method. Specifically, the tobacco stems are added in a drum tank, a certain quantity of hot water is added in the drum tank while the drum tank rotates, and the tobacco stems absorb water for 30 minutes; after being cooled down to room temperature, the tobacco stems containing water are added in another drum tank, and a certain quantity of microbial seed liquid is added into the other drum tank to realize microbial inoculation while the other drum tank rotate; and after inoculation, the tobacco stems are fed in cultivating frames, the cultivating frames are stacked on a movable storage cage in a certain mode so as to vibrate and increase feeding rate, the storage cage is placed in a fermentation chamber or a fermentation container to realize solid-state fermentation, ventilation is carried out according to needs, and after fermentation is finished, microbial spore is sucked. The new system suitable for solid-state fermentation of tobacco stems and the corresponding solid-state tobacco stem fermentation method can increase mechanical level and automatic level of a production process of solid-state fermentation of the tobacco stems, increase spatial feeding coefficients of solid-state fermentation materials, and accordingly improve production efficiency of solid-state fermentation of the tobacco stems.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for solid-state fermentation of tobacco stems and a new solid-state fermentation system. Background technique [0002] Tobacco stems are the thick and hard veins of tobacco leaves, accounting for about 25% to 30% of the leaf weight. Leaf stems are gradually separated during tobacco processing. Its shape is long strips of different thickness and length. It is often cut into shredded stems in cigarette production, and used in cigarette processing in a certain proportion with shredded tobacco. But the tobacco stem that also has cannot be fully utilized. The chemical composition of tobacco stem is complex, mainly including cellulose, hemicellulose, pectin and so on. The cellulose content accounts for about 20%. Tobacco stems can be processed into tobacco stem fibers, tobacco stem fermentation extracts, etc. in the cigarette industry through microbial fermenta...
