The object of the present invention is to provide a novel online drying method for heated cigarette cut tobacco, which comprises the following two steps: step 1) increasing the moisture content of natural tobacco leaves to 18.5-20.5% through the leaf making section, cutting into shreds, and shredding the width of the shredded tobacco. Controlling to 0.9 to 1.1 mm; Step 2) Drying the cut tobacco with high-temperature air flow to reduce the moisture content of the cut tobacco to 9.5-10.5%; Step 3) Carrying out a warming and moistening treatment for the cut tobacco, increasing the temperature of the cut tobacco to 86°C±3, and controlling The content of the humectant in the cut tobacco is 2-6%; step 4) the cut tobacco is subjected to drum drying treatment to reduce the moisture content to below 3%.

The invention discloses a process parameter optimization method for multi-process industrial production process, comprising the following steps: Step S101: analyzing the production process, identifying the final quality index of the industrial production process, the quality index of each process and the process parameters in the process ; Step S102: Based on the batch number, associate the final quality index with the quality index of each process and the process parameters in the process to form a batch record, collect multiple batch records, and form a modeling data set; step S103: Screen out the final quality index and the quality index data of each process from the modeling data set to form a final quality index prediction data set; the present invention obtains the optimal quality index of each process through the optimal final quality index model, and obtains the best quality index through each process The optimal process parameters of each process can be obtained through the quantity index, that is, in the production process, by controlling the process parameters to be the optimal process parameters, a higher final quality index can be obtained, and the industrial production efficiency can be improved.

The invention belongs to a low-temperature CO2 expansion process for shredded tobacco, comprising the following steps: ① immerse shredded tobacco with a moisture content of 18% to 20% in liquid CO2 for 60 to 100 seconds to obtain shredded tobacco with dry ice; ② immerse shredded tobacco with dry ice obtained in step ① After the shredded tobacco is loose, it enters the HT steam expansion device through quantitative feeding for pre-expansion; ③The pre-expanded shredded tobacco is sent to the air dryer for expansion and drying, and the flow rate of the hot air entering the air dryer is 21m / s~23m / s , The temperature is 200 ℃ ~ 230 ℃. Adopting the process of the present invention reduces the treatment intensity of the carbon dioxide process, reduces the fragmentation during the expansion process, improves the whole cut rate of the expanded cut tobacco, and the whole cut rate is 74% to 78%, reduces the broken shred rate, and the broken shred rate is 1.4% to 2.1%, Improve the change rate of the whole yarn rate, and the change rate of the whole yarn rate is 73% to 77%.

The invention relates to a tobacco leaf puffing treatment device for preparing tobaccos in a tobacco factory, in particular to an improved novel tobacco shred expansion device. By the expansion device, expansion treatment is carried out on tobacco shreds which are soaked by carbon dioxide liquid and form dry ice by high-temperature airflow. The improved novel tobacco shred expansion device is in a Z-shaped tubular structure with an inlet and an outlet which are horizontally arranged, the inlet is connected with a hot air conveying device, the outlet is connected with a tangential separator, the position of the inlet is also communicated with a feeding mechanism, and the whole range of the tubular structure adopts an oblong section, wherein the area of the oblong section of an upright tubesection is gradually increased from an inlet end to an outlet end, the length of the longitudinal long axis of the oblong section is gradually increased, the length of the transverse short axis is unchanged, and hot air conveyed by the hot air conveying device is parallel to the direction of the transverse short axis in the direction of the inlet. The expansion device enhances the heat exchange effect of tobacco shreds in the expansion device greatly, also prevents the collision between the tobacco shreds and enhances the shred straightening rate.

The invention discloses a process for pre-pressing and boxing filamentary tobacco materials, through material temporary storage-cigarette box flipping and docking-feeding lifting-thinning metering-reciprocating material spreading-material pre-pressing-material boxing-cigarette box The production process of temporary storage and distribution adopts the traditional vertical box packing process, which can not only improve the packing uniformity and packing density of tobacco materials in the box, reduce transportation costs, but also have low requirements on the site and reduce process equipment The floor area and factory design requirements can indirectly reduce the equipment cost, and can effectively reduce the shred rate. It is suitable for packing and distribution of tobacco materials such as shredded tobacco, expanded shredded tobacco, thin slices, and shredded stems. It has a wide range of applications.

The invention discloses a method for enabling carbon dioxide expanded tobacco to highlight the sweet aroma style. The method is characterized by comprising the steps that before tobacco leaf expansion, primary feed liquid is added into tobacco leaves, then carbon dioxide expansion is performed after tobacco leaves are shredded, and finally secondary feed liquid is added into the expanded tobacco shreds, wherein the primary feed liquid is water solutions of monosaccharide, disaccharide and polysaccharide, and the secondary feed liquid is prepared from heterocyclic oxygen spice, heterocyclic nitrogen spice, sweet aroma style tobacco essence molecule distillation light component, a sweet aroma style Maillard reaction product, tobacco source low molecular weight monomer spice and a fruit extract. The method can improve the physical structure of expanded tobacco and reduce technological residues, and can specifically compensate for aroma substance losses caused by expansion, add high-quality aroma in expanded tobacco, cover offensive odor, reduce irritation and reduce dryness sensation.

The invention provides a flash evaporation puffing and roller drying treatment process for stalk shreds. According to the treatment process, jet type stalk shred heating and humidifying equipment and steam-heated drum-type shred baking equipment are adopted, the filling value of the stalk shreds is increased from 5.6 cm<3> / g to 6.0 cm<3> / g, namely increased by 7.1%, the processing resistance of the stalk shreds is markedly increased, the stalk shred output rate is increased by 0.6%, the integral stalk shred rate is increased by 1.4%, the outlet water content of the dried stalk shreds is uniform, the water content fluctuation is controlled within a range of + / -0.4%, the woody gas influence caused by stalk shreds in the cigarette product is effectively avoided, and at the same time, the dried stalk shreds are better in water content uniformity and lower in water content fluctuation.
