Description
Technical field
The invention belongs to technical field of tobacco processing, be specifically related to the package conditioning and loosening technology and equipment of pretreatment section in a kind of production of cigarettes.
Background technology
Along with the development of cigarette technology, Lamina bale also exists greater advantage in packaging, transport, storage etc.Therefore, in production of cigarettes, the raw material of tobacco leaf mostly are the 200kg tobacco bale being of a size of 1115 × 690 × 725 or 1136 × 720 × 725 packagings.Tobacco bale needs after entering the production line of cigarette enterprise first to carry out loosening and gaining moisture process, just can carry out follow-up processing.Current process treatment process has Three models: one is tobacco bale section+cylinder loosening and gaining moisture, and two is section+vacuum conditioning+cylinder loosening and gaining moistures; Three be microwave ease back+machinery loose+cylinder loosening and gaining moisture.
Research application shows, the existing above-mentioned three kinds of tupes of Cigarette Industrial Enterprise exist certain inadaptability when producing high-grade raw tobacco material, are mainly reflected in following several respects.
1, the processing technology of tobacco bale section+cylinder loosening and gaining moisture be with cutting machine 200kg cutting cigarette packet become 40 or 50kg cigarette block after send in damping machine and carry out loosening and gaining moisture.Due to the temperature of cigarette block and moisture all lower, make making of tobacco leaf broken very large in the rolling of the inducer cigarette block of damping machine.According to the introduction of Chinese patent CN101697837, Percentage of large and middle size strips reduces by 6% ~ 8%, and fragment rate increases by 0.4% ~ 0.5%.On the other hand for making smoked sheet reach better loose effect, existing device for loosening and gaining moisture return air temperature mostly is about 65 DEG C, and with this understanding, the aroma quality of high-grade raw tobacco material and perfume quantity are lost larger.Research shows, high-grade raw tobacco material needs in lower return air temperature (50 DEG C) treatment conditions, more effectively could play potential quality and the use value of tobacco leaf.But adopt the processing technology of tobacco bale section+cylinder loosening and gaining moisture with this understanding, loose effect is poor, and tobacco flake loosening rate is many between 90% ~ 95%, can not complete the task of loosening and gaining moisture well.On the other hand, in loosening and gaining moisture process, smoked sheet is heated uneven.One is that raw tobacco material is pressed into block vanning accumulating after beating and double roasting, and lump material enters loosening and gaining moisture cylinder, and material center has sub-fraction tobacco leaf and can not effectively scatter, and this part tobacco leaf cannot thermally equivalent in loosening and gaining moisture process.Two to be that the change of steam flow makes the smoked sheet after scattering be heated uneven.
The processing technology of 2, section+vacuum conditioning+cylinder loosening and gaining moisture enters in vacuum conditioner after tobacco bale is loaded an iron case to carry out moisture regain process, and the tobacco bale after process enters cylinder and carries out loosening and gaining moisture after hog shred is loose.Such processing procedure, tobacco leaf makes broken reduction in cylinder, and the loosening ratio of discharge blade is high, but due to the drop temperature of vacuum conditioning be 50 ~ 60 DEG C, the processing time is 10 ~ 15 minutes, causes this perfume of tobacco leaf to lose larger.
3, microwave ease back+machinery is loose+processing technology of cylinder loosening and gaining moisture first tobacco bale is sent in microwave equipment to carry out the process that eases back, it is loose then to carry out machinery, finally carries out cylinder loosening and gaining moisture.The material entering cylinder is loose blade, is conducive to the moisture regain process of tobacco leaf.But because the tobacco bale moisture after microwave treatment is very low, therefore make broken very large in mechanical relaxing process, meanwhile, it is larger that microwave treatment also can cause this perfume of tobacco leaf to lose.
This perfume of maintenance tobacco existed when producing high-grade raw tobacco material in view of existing device for loosening and gaining moisture with complete loose task this to contradiction, Cigarette Industrial Enterprise is in the urgent need to researching and developing a kind of tobacco bale low intensity loosing conditioning technology and equipment.So-called " low intensity loosing conditioning " refers to that tobacco bale is in loosening and gaining moisture processing procedure, adopt lower treatment temperature (temperature of tobacco leaf is no more than 50 DEG C in processing procedure), more low intensive mechanism, reduce the impact on material interior quality to greatest extent, ensure that sheet cigarette is loose, minimizing is made broken.
Summary of the invention
