Description
Technical field
The present invention relates to a kind of forming drying equipment, especially a kind of reconstituted tobacoo shapes drying equipment, further relates to tobacco
Thin slice shapes drying means, belongs to tobacco equipment field.
Background technique
In tobacco leaf production enterprise, the forming of thin slice in existing reconstituted tobacco sheets production line and dry method and set
It is standby, generally using paper process, roll-in method, thick slurry method or dry method etc..
It is general agglomerating after the materials such as tobacco powder, natural fiber, adhesive, water and ingredient mix (kneading) in roll-in method
Shape, moisture content are rolled into bandcast tobacco thin slice by pressure roller, carry out shaping and dry generally 30% or so.Since mixing (is pinched
Close) after material need to have by roll-in roll flakiness condition, and by mesh belt tunnel dry.Material under this state
Generally at bulk, without mobility, therefore in mixing (kneading) process, tobacco powder, natural fiber, adhesive, water and ingredient etc.
Material mixing uniformity is poor, it is difficult to accomplish to be uniformly mixed consistent, various substances on the reconstituted tobacoo for causing roll-in rolling to become band
The consistency that is evenly distributed it is poor, multiform influences reconstituted tobacoo quality of finished at white dirt, and intensity is poor, simultaneously because by
The limitation of (kneading) technical process is mixed, the additional proportion of natural fiber, adhesive and ingredient etc. is limited, also leads to tobacco
Thin slice product intensity is poor, and resist processing is poor, frangibility, easily makes broken, limits the application range of roll-in method thin slice finished product.
In thick slurry method, the materials such as tobacco powder, natural fiber, adhesive, water and ingredient are mixed into paste by slurry device
Thick slurry, various material mixing uniformity is preferable, and material under this state generally at paste thick slurry shape, has certain fluidity, contains
Water rate is generally 80% or so.Since mixed material water ratio is high, there is certain mobility, it need to be dry using steel band when dry
Dry, cigarette slurry is coated on formation bandcast tobacco thin slice on steel band, enters drying alley with steel band (cyclic annular sheet metal), passes through pancake
Mode is shaped and is dried.The cigarette of this method is starched and forms bandcast tobacco thin slice on steel band by way of coating, random larger,
Leading to finished product low density, sheet thickness uniformity is poor, simultaneously because cigarette slurry moisture content is high, it, can shape when steel band shows that temperature is high
At bubble, bubbles burst just forms hole on thin slice, influences final product quality.In addition steel band drying mode is lower than in material moisture
It is unfavorable for the evaporation of material moisture in the state of 40%, drying efficiency is low, and production capacity is limited, and steam consumption quantity is big.
In paper process, enter paper machine after first using extracted tobacco raw material, insoluble substance or addition natural fiber that slurry is made,
Gauze is preliminarily formed, is added in gauze together after water-soluble extract is concentrated with additive, is finished product after dry.Processing system
When making, certain tobacco components can be extracted or removed from water-soluble substances, and the modulation of homogeneous tobacco leaf is mostly used this method.The method is produced
Thin slice, physical strength is high, and wet strength is good, and non-breakable, bulk density is light, and burning velocity is fast, and it is low to generate tar content.However
Its production technology is complicated, and cost of investment and energy consumption are high, and product yield is low, and purification by liquid extraction object dip-coating or spray to is copied
Paper is made in sheets of fibres chip base, and globality is slightly worse, will appear fiber in following process process and is detached from, it is existing hair and powder dropping occur
As.
Thus, it is badly in need of a kind of device and method for promoting tobacco sheet quality while reducing energy consumption and cost at present.
