Description
Technical field
The invention belongs to papermaking-method reconstituted tobaccos technical field is and in particular to a kind of carry out cabo extraction and discongest simultaneously
Method and device.
Background technology
At present papermaking-method reconstituted tobaccos field cabo extracts, carding process method mainly has two kinds, one kind be first discongest after
Extract, one kind is first to extract to discongest afterwards.
The method of cabo extraction process commonly used container+hot water+stirring+auxiliary at present, main flow equipment has leaching to filter tank, many
Function extraction pot, dynamic extraction pot and the process equipment such as hot reflux extracting-concentration machine group, ultrasonic enhanced extraction, microwave extraction.
Ultrasonic enhanced extraction, microwave extraction are extraction processes newly developed in recent years.Ultrasonic enhanced extraction can be shaken using ultrasound wave
Dynamic energy enhanced dispersion process, makes solvent easily immerse solid solute, solid solute is easily diffused into solid-liquid from solid interior
Interface, thus accelerate extraction process.Shortcoming is to be limited by ultrasonic power, and the economy of large-scale production is bad.Microwave carries
Take using microwave to the effect heated solvent of polar molecule and medical material, make cell wall rupture, reach the purpose accelerating extraction.Microwave
Extract and occurred power to be limited by microwave, there are some engineering problems when amplifying production scale.Carried using intensified by ultrasonic wave
Take and be provided to improve extraction efficiency and extraction ratio with microwave extraction.
Cabo before or after extracting mainly is extruded, makes tobacco stalk fibre loose, by machinery by cabo carding process
The mode rubbed makes cabo be separated into ribbon silk-shaped tobacco stalks along machine direction.Produce in papermaking-method reconstituted tobaccos both at home and abroad at present
In technique, it is substantially first cleaning cabo, then the cabo after cleaning is sent directly into extraction process section and is extracted, by solid
Liquid separates and carries out solution fibre after extracting.Solve fine after extraction, repulping after solution fibre, process because cabo first passes through rubbing, prepared slurry
Material ratio is more uniform, and the increase fiber with making beating revolution is sufficiently separated, and wire-dividing broom purification degree is higher, and therefore beating degree increase is very
Hurry up, the intensity of chip base is good, and quality is also very homogeneous.
But extract after solution fibre also have its corresponding shortcoming, because cabo is not broken, contact with solution area little,
Extraction efficiency can therefore suffer from affecting；In addition during some cabo defibrinations, stress is larger, and fibrous fracture is a lot, the fiber of some cabos
During defibrination, stress is less is separated, and therefore piece rheobase and quality all can be affected.
If cabo carries out solving fine process to cabo before sending into extraction process section after cleaning, it will significantly improve follow-up
Extraction efficiency and extraction ratio.Cabo after solution fibre becomes card shape, increases with the contact area of extracting solution, extracting solution easily enters cigarette
In stalk, save extraction time hence it is evident that improve extraction efficiency.But cabo moisture content is low, in discongesting processing procedure before extracting
Cabo bundle suffers considerable damage, and pulp quality is poor, is unfavorable for the manufacture of product.
So by studying suitable extraction defibering method, while extracting and discongest completing, reaching extraction and discongest effect
Rate is high, quality is good, low energy consumption purpose, is the trend of current industry development.
Research papers:
Enterprise's technology development the 4th phase of volume 32 " extract and the impact to papermaking-method reconstituted tobaccos quality for the thread rolling technique and its
Improve "
Summary: with the continuous progress of China's cigarette producing process, paper process is applied increasingly in reconstituted tobacco production
Extensively.The quality how improving papermaking-method reconstituted tobaccos further is the emphasis of Modern cigarette industry manufacturing enterprise research.Article passes through
Labor to papermaking-method reconstituted tobaccos technique, draws the impact to papermaking-method reconstituted tobaccos quality for the technology controlling and process, and proposes
It is correspondingly improved scheme.
" Nicotiana tabacum L. science and technology " the 07th phase " improvement of papermaking-method reconstituted tobaccos production technology " in 2009
Summary: for solving produced problem in papermaking-method reconstituted tobaccos production process, add one section in original production process
Thread rolling is processed, and have studied thread rolling machine rotating speed, washing temperature, the impact to thread rolling effect for the cabo moisture content.Analyze addition thread rolling
Process on effect of extracting, making beating efficiency, the rheobasic impact of piece.Result shows: optimum process condition is: the rotating speed of thread rolling machine is
200r/min, before thread rolling, washing temperature is 40 DEG C, and during thread rolling, the moisture content of cabo is 30%～35%.Meeting production requirement
In the case of, add thread rolling to process and can improve extraction efficiency 15% about, save beating time and energy consumption more than 30%.
Paper and phase in the end of the year 2014 of papermaking 10 " the direct shredding process of cabo twin screw pulper and its application "
Summary: for studying the impact to twin screw thread rolling machine filamentation effect for the cabo pretreatment condition, investigate steaming time,
Cabo moisture after decatize, the impact to cabo shredding yield for the cabo thread rolling hop count.Test result indicate that: adjust the initial moisture of cabo
Carry out individual composition for 40%～50%, with the prolongation of steaming time, cabo moisture increases sharply, and moisture is increased by initial value
The moisture change of cabo to after 58.14%, 10min tends towards stability, it is thus determined that 10min is cabo preferably steaming time；
40%～50%, after individual composition, moisture reaches 55%～60% to the initial moisture Control of cabo, should under the conditions of cabo thread rolling effect
Really best；Cabo single hop thread rolling after decatize, stem qualification rate is 48.63%, and through 3,4 sections of thread rolling, meticulous stem causes
Stem is wound around, and qualified stem sieves difficulty, and qualification rate declines, and creates much components in small, broken bits.Therefore, cabo decatize filamentation
Optimal treatment condition be: moisture 40%～50% after regaining moisture of cabo, optimal steaming time 10min, after decatize, moisture reaches
55%～60%, two sections of thread rollings, with this understanding, qualified stem yield is 68.91%.
Heilungkiang papermaking the 2nd phase in 2010 " application in producing tobacco flake in method similar to papermaking of thread rolling technology " makes a summary: Nicotiana tabacum L.
Thin slice is a kind of using offal, cabo, fragment etc. as raw material, the reproduction being reconfigured by the special course of processing
Product.The physical property of reconstituted tobacoo is similar to Nicotiana tabacum L., can be used for tobacco blend as a kind of effective flavoring agent, can be new for exploitation
Product provides effective process meanses, can mitigate the harm to smoker again.Have studied thread rolling herein and process the optimal of raw material
Process conditions and the impact to chip base, process the tensile index obtaining the chip base that slurry is obtained significantly better than at non-thread rolling through thread rolling
The chip base tensile index that reason raw material obtains.In addition the chip base filling capacity that the slurry that the cabo processing through thread rolling obtains is obtained is bright
The aobvious raw material being better than non-thread rolling process.
