Description
Technical field
The invention belongs to technical field of tobacco processing, be specifically related to a kind of fluidized bed type tobacco shred blending perfuming device and mix join perfuming method.
Background technology
The difference of various brands cigarette is mainly pipe tobacco formula, and tobacco shred blending and perfuming are the important steps in production of cigarettes.Tobacco shred blending is the feature of comprehensive different pipe tobacco, form compound fragrant, perfuming is the deficiency in order to make up raw tobacco material suction sensation, pipe tobacco mixture homogeneity directly affect tobacco light after natural taste, whether the perfuming uniformity decides cigarette fragrance and stablizes, therefore, tobacco shred blending and perfuming uniformity play an important role to cigarette quality.It is adopt cabinet type feeding machine to carry out mixing to mix and join that tradition tobacco shred joins perfuming process, utilizes in drum-type Perfuming machine and carries out perfuming.The problem such as poly-to fall, the long and feeding capacity fluctuation of putty, feeding is larger because cabinet type feeding machine exists feeding flow, be difficult to the uniformity ensureing tobacco shred blending; Then there is perfuming lack of homogeneity in drum-type Perfuming machine, makes the problems such as the broken serious and fragrant liquid proportion of goods damageds are high.How to improve tobacco shred blending perfuming uniformity, promote finished cut tobacco quality, thus promote cigarette product quality, become the research emphasis in cigarette primary processing technical process processing quality control direction.Chinese patent CN101116535 A discloses a kind of process for allocating and mixing tobacco shred, before perfuming operation, increase a mixed wire process, makes major ingredient pipe tobacco and mixes tobacco blending silk and enter in mixed silk cabinet and carry out stirring, mixing.The method improves the uniformity of tobacco shred blending to a certain extent, but can not ensure major ingredient pipe tobacco and mix tobacco blending silk and mix completely, and mixed silk cabinet is owing to existing mechanical agitation, increases energy consumption and pipe tobacco broken rate.Patent CN1830336 A discloses pipe tobacco vacuum perfuming method and equipment, principle of negative pressure is adopted to separate out the intracellular air of pipe tobacco and portion of water, add atomization spice liquid by spray and increase measuring containing fragrant of pipe tobacco, and by the negative pressure in pipe tobacco, liquefaction spice liquid in pipe tobacco surface is sucked in cell, make inside and outside pipe tobacco, to obtain even spice liquid.The method better solves tobacco perfuming uniformity and absorbefacient problem, but owing to adopting vacuum equipment, can only intermittently operated, affect production capacity, and owing to needing the environment of negative pressure, increase energy consumption and make broken.Therefore, developing a kind of tobacco shred blending perfuming device that can work continuously is very favorable for modern production of cigarettes.
Summary of the invention
Being of first improving eyesight of the present invention provides a kind of fluidized bed type tobacco shred blending perfuming device that can work continuously, and the second object is to provide application said apparatus to carry out the method for tobacco shred blending and perfuming.
The first object of the present invention realizes like this, comprise feed arrangement, mix equipped to put, perfuming device, described feed arrangement comprises mixes tobacco blending silk feed arrangement and main pipe tobacco feed arrangement, mix the equipped fluidized bed type that is set to and mix equipped putting, comprise the pore gas distributor upward of mixing bunker and the setting of mixing bunker bottom, perfuming device comprises pneumatic conveying bed and perfume burner; The described mixing bunker mixed tobacco blending silk feed arrangement and main pipe tobacco feed arrangement and pass into from top, the blanking section bottom mixing bunker is communicated with pneumatic conveying bed; Pneumatic conveying bed end arranges surge bunker, arranges discharge nozzle bottom surge bunker; Mixing bunker and surge bunker top arrange rising airway, and gas distributor is communicated with source of the gas with pneumatic conveying bed.
The second object of the present invention is achieved in that and comprises the following steps:
A, fluid bed are formed: the gas in source of the gas is sent into mixing bunker and pneumatic conveying bed, and in mixing bunker, gas forms dispersion ascending air through gas distributor, and in pneumatic conveying bed, gas is formed towards the delivery air of surge bunker;
B, pipe tobacco mix: mix tobacco blending silk and main pipe tobacco respectively through mixing tobacco blending silk feed arrangement and main pipe tobacco feed arrangement falls into from the top of mixing bunker, run into dispersion ascending air, pipe tobacco fully mixes; Pipe blend enters pneumatic conveying bed through blanking section;
C, spices mix: pipe blend, along pneumatic conveying bed motion, mixes with atomization spices when flowing through perfume burner;
D, degassed discharge: the pipe blend after perfuming is delivered to surge bunker by gas, gas is discharged through rising airway, and finished cut tobacco falls into discharge nozzle and discharges.
The key problem in technology of tobacco shred blending and perfuming is mixing of materials.In tobacco shred blending link, the ingenious principle that make use of fluid bed of the present invention, mixing bunker and gas distributor constitute bubble type fluid bed.Material falls into above mixing bunker, and the ascending air that gas distributor produces makes pipe tobacco material seethe up and down (fluidization of solid), not having the abundant mixing achieving material in churned mechanically situation, not only improving mixed effect, and reducing percentage of damage.In tobacco perfuming link, the present invention still by means of fluidized bed principle, with the pneumatic conveying bed feeding tobacco-thread of tubular structure, the air-flow promoting pipe tobacco makes pipe tobacco fluidization, the i.e. abundant loose condition (of surface) of pipe tobacco, the pipe tobacco of this state more easily fully mixes with atomization spices, and need not by mechanical agitation.Apparatus of the present invention structure is simple, requisite space is few, continuous operation is strong, can realize large-scale production, easy and simple to handle, quick, practical.
