摘要： PROBLEM TO BE SOLVED: To provide a means for rapid drying and reordering of tobacco in large quantities which are processed in a short amount of time and in very little floor space.
SOLUTION: The method for rapid drying, cooling and reordering of the tobacco comprises a process for placing the tobacco on a continuous conveyor belt in fixed thickness, a process for transporting the tobacco on the conveyor through a dryer using a fluidized bed of heated air, a process for transporting the tobacco on the conveyor through a cooler using a fluidized bed of peripheral air, a process for transferring the tobacco to a steam tunnel having a vibration conveyor and a process for reordering the tobacco in the steam tunnel. The process for transporting the tobacco through the dryer has a process for sending air heated to a first fixed temperature to a first heating zone, a process for circulating the air in the first heating zone, a process for sending air heated to a second fixed temperature from the first heating zone to a plurality of downstream heating zones, a process for circulating the air in a plurality of the downstream heating zones, a process for reducing the water content of the tobacco to about 5%, a process for raising the temperature of the tobacco from about 200°F (about 93.3°C) to about 280°F (about 137.8°C).

摘要： A process to improve the smoke quality and mechanical properties of reconstituted tobacco is accomplished by adding tobacco materials to an aqueous solution containing ammonium salts and urea. The resulting first tobacco slurry is then pressurized under steam pressure to at least 60 psi for a period of from 1 to 5 minutes then depressurized rapidly to ambient. The depressurized tobacco is then formed into a second tobacco slurry wherein the soluble components within the tobacco is removed. The resulting tobacco residue is then prepared into a reconstituted tobacco sheet and the extract is then concentrated to a solids level of at least 30 percent by weight of solids which is added back to the reconstituted tobacco sheet for further processing into smoking articles.

摘要： A high humidity drying apparatus for cut tobacco is shown. The apparatus has a furnace which heats circulated air within the apparatus. The air is forced through a first arcuate elbow (14) which has a tobacco air inlet (12) located thereon for inserting the cut tobacco into the airstream. The tobacco is then redirected into a vertically extending drying chamber (20). The air entrained tobacco is then forced through a second arcuate elbow (26) which places the tobacco into a tangential separator (30) for removing the tobacco from the heated air. The separator has dual air exhausts (32, 36), each leading to a high efficiency cyclone (40, 42) for further removal of the tobacco dust from the circulated air. All of the air is then passed back to the furnace for heating and then recirculated through the drying apparatus.

摘要： Invenţia se referă la filtrele pentru ţigări cu caneluri pentru dirijarea fluxului de aer ventilator spre capătul filtrului. Filtrul conţine un miez de filtrare poros 1, care se află într-un înveliş 2 cu canelură 3, o fâşie de hârtie de muştiuc permeabilă la aer 4 şi cu orificii de aeraj 6,7 pentru unirea filtrului cu miezul de tutun 5. O parte din învelişul 2 aflat în caneluri este executată impermeabilă la aer, iar restul lui care se află pe suprafaţa miezului filtrant este executat permeabil la aer. În timpul fumatului aerul ventilator este aspirat simultan prin orificiile 6 în canelurile 3 şi prin orificiile 7 în miezul filtrant 1 prin regiunile permeabile la aer învelişului 2. Aerul, intrând în canelurile 3, trece spre capătul deschis al canelurii şi nimereşte în gura fumătorului. Iar aerul care intră în miezul filtrat se amestecă acolo cu fumul care provine din miezul de tutun

摘要： Invenţia se referă la filtrul pentru ţigări cu noi proprietăţi de aeraj, iar într-o anumită măsură ea se referă la filtrul pentru ţigări cu caneluri pentru circularea curentului de aer spre capătul de ieşire al filtrului în anumite condiţii de fumare, pentru pomparea fluxului de fum de tutun amestecat cu un curent de aer prin filtru către fumător, în alte condiţii specifice de fumare, pentru pomparea cel puţin a unei părţi a aerului ventilator din canelurile indicate în corpul filtrului pentru malaxarea şi diluarea ulterioară a fluxului de fum de tutun care trece prin filtru către fumător. Scopul invenţiei constă în sporirea eficacităţii filtrării fumului. Filtrul include în sine un mies de filtrare poros 1, care se află într-un înveliş impermeabil la aer 2 cu o mulţime de caneluri longitudinale 3, implementate în miezul de filtrare, material de ambalaj 4 pentru cuplarea filtrului cu miezul de tutun 5. În înveliş este executat un rând circular de orificii 7 pentru avansarea aerului în filtru. În zona fiecărei caneluri în înveliş sunt executate orificii suplimentare 8, diametrul cărora este mai mic decât diametrul orificiilor 7.Figuri:3

摘要： A filter for a cigarette includes a porous filter rod circumscribed by a non-porous or air impermeable wrapper, and ventilating air grooves embedded in the wrapped filter rod which extend from one end of the filter rod a preselected distance generally longitudinally of the filter rod. An air permeable tipping material circumscribes the wrapped filter rod which provides a path therethrough for ventilating air flow only into the grooves. The walls of each of the grooves defined by the wrapper, in one form of the invention, is permeable to air over virtually its entire length, and in another form of the invention is permeable to air flow only adjacent the mouth end of the filter. Under certain smoking conditions most, if not all of the ventilating air will flow from the grooves into the smoker's mouth through the open end of the grooves at the mouth end of the filter rod. Under certain other smoking conditions, at least a part of the ventilating air will pass through the air permeable walls, or portions thereof, of the grooves and into the filter rod wherein it co-mingles with and dilutes the smoke flowing therethrough.

摘要： A method of manufacturing tobacco smoke filter of filamentous material with at least one end thereof having a preselected fused area embedded in and over at least a portion of the cross-sectional area thereof having a preselected fused area extending over at least a portion of the cross-sectional area thereof to provide a flow directing baffle to direct smoke through the unfused end portion. The method includes forming a longitudinally extending porous rod of fusible material, cutting the rod into filter unit lengths and conveying the filter units in a longitudinal path normal to the longitudinal axis of the filter units past a fusing station located to one side of the conveying path. The fusing station forms an indented and fused area in one end of each filter unit as the filter units are conveyed there past. The fusing station can be a rotating wheel with conical teeth corresponding to the configuration of the indented area which teeth are embedded into the filter units. As the filter units are conveyed past the wheel the wheel rotates embedding a tooth into a filter unit.
