A kind of offal is processed into the method for expanded cut stem
Technical field
The invention belongs to tobacco processing throwing technical field, be specifically related to a kind of method that tobacco stalk raw material is processed into expanded cut stem with good cigarette performance.
Background technology
Cigar mill to the processing of offal mainly be with the offal behind the beating and double roasting after washing, moisture regain, chopping, series of processes such as reinforced, by stem expansion and the dry expansion effect of handling back acquisition stem, improve its filling rate, form finished cut tobacco with the leaf silk blending of making again.Traditional offal is processed into the mode that stem generally adopts cutting, along axially cutting into slices by certain width perpendicular to offal, form stem, the stem that this chopping mode forms mostly is sheet greatly, widely different with the leaf filament shape, easily form nominal phenomenon when rolling, and tobacco stalk fibre is damaged, influence expansion effect.For this reason, the inventor is at the deficiencies in the prior art, researched and developed a kind of can be under the situation of not destroying tobacco stalk fibre, obtain identical with mechanical system with the pipe tobacco shape, the offal that improves offal utilization rate and expansion drying effect is processed into the method for expanded cut stem, evidence, effect is good.
The specific embodiment
1, the purpose of innovation and creation
The object of the present invention is to provide a kind of operation easy, process stabilizing is processed into offal the method for expanded cut stem reliably.
2, technical scheme
The object of the present invention is achieved like this, comprises following operation:
A, with the offal behind the beating and double roasting, under 140-150 ℃ of temperature, heating moisture regain and handle improving the moisture content of offal to 18-20%;
B, offal is beaten weak point, the offal length that forms technological requirement is to 20-40mm;
Stalk skin and dust are removed in C, offal washing;
D, storage make offal fully absorb moisture more than 2 hours;
E, raising temperature are carried out the moisture regain second time to 140-150 ℃ and are handled (secondary steams stalk), make offal fully absorb moisture to moisture content 35-42%;
F, offal is pushed, make fiber loose, rub the stalk machine with the hands by machinery again and make offal be separated into stem along machine direction;
G, evenly spray spices liquid by technology;
H, the offal silk after rubbing with the hands is carried out expansion process under 130-150 ℃ of temperature, and be dried to moisture content 12.5% typing, improve its filling capacity.
The length of offal should be worked as suitable length with the offal intercepting in advance according to the specific requirement of cigarette process in the B operation, is generally 20-40mm.
Extruding is extremely important in the F operation, generally with tobacco stem flattener offal pushed, and can make offal loose effectively, is convenient to offal and enters and rub the stalk machine with the hands and make offal be separated into the ribbon silk-shaped tobacco stalks.The mode of rubbing stalk with the hands can adopt mechanical screw type to rub the stalk machine with the hands, as double-screw type, and three screws, four screws or five screws.Screw rod can adopt the equal diameter screw rod or become the diameter Conic thread rod.The pitch of screw rod can be divided into equidistant pitch and displacement pitch.
3, beneficial effect
The inventive method can be preserved the fibre machinery characteristic of offal effectively, improves the expansion character of offal silk, improves the cigarette performance of offal silk, has improved the height filling value cigarette quality of offal.This method technology is easy, and is reliable and stable.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment, but the present invention is not imposed any restrictions.
Accompanying drawing is a process chart of the present invention.
The specific embodiment
As shown in the figure, the inventive method comprises regaining moisture of cabo, beats stalk, washes stalk, Terrier Storage, offal secondary (steaming stalk) humidification, presses stalk, rubs operations such as stalk and stem expansion drying with the hands.
Embodiment one
Offal behind the beating and double roasting, after tunnel type regaining moisture of cabo machine heated the moisture regain processing for the first time, satisfied beating obstructed requirement in 150 ℃ of following humidifications to 18-20%.The offal of length 〉=20mm is beaten be as short as 20-40mm with making the stalk machine.Stalk skin and dust are removed in washing, humidification is sent into the storage cabinet storage more than 2 hours to 30%-35% simultaneously, offal is sent into the processing (secondary steam stalk) that gets damp again for the second time of warming and humidifying machine afterwards, to 35%-42%, further improves the flexibility and the anti-processability of offal at 150 ℃ of humidifications.Spray spices liquid by technological requirement, after tobacco stem flattener is pressed stalk to offal, make tobacco stalk fibre loose again, enter stranding stalk machine and make offal be separated into the thread stem of ribbon, diameter phi 0.1-0.5, length is 20-40mm.The stem of rubbing with the hands after obstructing carries out the higher filling capacity of stem expansion drying processing acquisition under 130 ℃, reach 12.5% stem moisture content, and is used for mixing formation finished product expanded cut stem with the leaf silk.
Embodiment two
Offal behind the beating and double roasting, after tunnel type regaining moisture of cabo machine heated the moisture regain processing for the first time, satisfied beating obstructed requirement in 140 ℃ of following humidifications to 18-20%.The offal of length 〉=20mm is beaten be as short as 20-40mm with making the stalk machine.Stalk skin and dust are removed in washing, humidification is sent into the storage cabinet storage more than 2 hours to 30%-35% simultaneously, offal is sent into the processing (secondary steam stalk) that gets damp again for the second time of warming and humidifying machine afterwards, to 35%-42%, further improves the flexibility and the anti-processability of offal at 140 ℃ of humidifications.By with implement an identical technology and carry out subsequent treatment, will rub stem behind the stalk afterwards and under 150 ℃, carry out the stem expansion drying and handle and obtain higher filling capacity, reach 12.5% stem moisture content, and be used for mixing formation finished product expanded cut stem with the leaf silk.
Embodiment three
Offal behind the beating and double roasting, after tunnel type regaining moisture of cabo machine heated the moisture regain processing for the first time, satisfied beating obstructed requirement in 145 ℃ of following humidifications to 18-20%.The offal of length 〉=20mm is beaten be as short as 20-40mm with making the stalk machine.Stalk skin and dust are removed in washing, humidification is sent into the storage cabinet storage more than 2 hours to 30%-35% simultaneously, offal is sent into the processing (secondary steam stalk) that gets damp again for the second time of warming and humidifying machine afterwards, to 35%-42%, further improves the flexibility and the anti-processability of offal at 140 ℃ of humidifications.By with implement an identical technology and carry out subsequent treatment, will rub stem behind the stalk afterwards and under 140 ℃, carry out the stem expansion drying and handle and obtain higher filling capacity, reach 12.5% stem moisture content, and be used for mixing formation finished product expanded cut stem with the leaf silk.
The moisture scope of the offal behind the beating and double roasting is generally 9-11% less than 11%.
Of the present invention have a simple process, reliable and stable, overcome existing offal throwing method destructible The fibre structure of offal and the drawback of mechanical performance have improved the expansion character of offal silk, improve offal The cigarette performance of silk, the quality of raising cigarette products.
