Abstract
The invention provides a recycling method of coating liquid of papermaking reconstituted tobacco. The recycling method of the coating liquid of the papermaking reconstituted tobacco is characterized by comprising the following specific steps of: collecting overflow liquid and leakage liquid obtained after coating of the papermaking reconstituted tobacco, filtering to remove tobacco slag and tobacco fiber, removing protein and other impurities with a membrane treatment system to obtain recycled liquid, and adding sorbitol, potassium citrate and guar gum into the recycled liquid, then, directly adding the recycled liquid into a preparation tank of the coating liquid for future coating use. According to the invention, the loss of polysaccharide macromolecules (main ingredients) and micromolecules (aromatic ingredients) such as alcohols, aldehydes, ketones and the like in the coating liquid can be avoided so that the quality of the recycled coating liquid of the reconstituted tobacco and the smoking taste of the reconstituted tobacco coated with the recycled coating liquid are not influenced.
Description
Technical field
The present invention provides a kind of recycling method of tobacco sheets by paper making method coating fluid, belongs to the tobacco sheets by paper making method preparing technical field.
Background technology
At present, the main method of producing reconstituted tobacoo both at home and abroad has three kinds: roll-in method, thick slurry method and paper process.Compare with roll-in method and thick slurry method, the preparation of tobacco sheets by paper making method has following advantage: can effectively reduce the harmful substance (especially tar content) in the cigarette; Effectively stablize the interior quality of cigarette raw material; Can efficent use of resources; Density is little, and porosity is high, and filling capacity is strong etc.Marlboro, the rate of mixing of reconstituted tobacoo can reach 25% in the internationally renowned brands such as 555, and China is also in the research of being devoted to the tobacco sheets by paper making method technology of preparing in recent years.
In the tobacco sheets by paper making method technology of preparing; Tobacco (like offal, offal etc.) is after extraction is filtered, through Separation of Solid and Liquid; Solid is processed sheets of fibres sheet base; Liquid concentration is processed the reconstituted tobacoo coating fluid, coating fluid is applied on the sheets of fibres sheet base again, and the section of oven dry back prepares reconstituted tobacoo.
During coating reconstituted tobacoo substrate; In order to guarantee the spreading rate of reconstituted tobacoo; Must adjust the roll spacing between two applicator rolls; Let the reconstituted tobacoo substrate fully absorb the reconstituted tobacoo coating fluid, therefore can cause a part of coating fluid from the gap of two rollers, to miss, this part leakage accounts for about 30% of total coating fluid.Method commonly used at present is that the leakage after the coating is centrifugalized; Remove wherein tobacco disintegrating slag and baccy fiber; And then be back to use in the coating fluid blend tank, mix with fresh reconstituted tobacoo coating fluid, but big molecule emplastic such as polysaccharide and little molecule aroma component such as alcohols, aldehydes and ketone can a large amount of losses in the coating fluid of centrifugation; Influence tobacco coating fluid quality, inhale flavor thereby influence reconstituted tobacoo.
Therefore,, can reduce the loss of reconstituted tobacoo coating fluid, improve the utilization rate of reconstituted tobacoo coating fluid not influencing under the reconstituted tobacoo suction flavor condition, significant for the production of tobacco sheets by paper making method.
Summary of the invention
The objective of the invention is to deficiency, a kind of recycling method of tobacco sheets by paper making method coating fluid is provided to prior art.Reconstituted tobacoo is produced coating overflowing liquid and leakage recycle in coating process, reduce the loss of tobacco coating fluid, raising reconstituted tobacoo spreading rate.
In order to achieve the above object; The invention provides a kind of recycling method of tobacco sheets by paper making method coating fluid, it is characterized in that, concrete steps are: overflowing liquid and leakage after the tobacco sheets by paper making method coating are collected; Filter and remove tobacco disintegrating slag and baccy fiber; Utilize film processing system to remove protein and form recovery liquid, in reclaiming liquid, add sorbierite, directly add the coating fluid blend tank behind potassium citrate and the guar gum and be coated with again with other impurity.
Preferably, described filtration step adopts multistage filtering equipment.
More preferably, the employed first order filter screen of described multistage filtering equipment order number is 20 orders, and second level filter screen order number is 60 orders, and third level filter screen order number is 120 orders, and fourth stage filter screen order number is 200 orders.
Preferably, the film that described film processing system adopted is that the aperture is the hollow fiber ultrafiltration membrane of 0.01～0.075 μ m.
Preferably, the difference when reconstituted tobacoo coating fluid and the density that reclaims liquid is 0～0.05g/cm
2The time, the part by weight that reclaims liquid and the sorbierite that is added is 100:0.5～1.5, and the part by weight that reclaims liquid and the potassium citrate that is added is 100:1.0～2.0, and the part by weight that reclaims liquid and the guar gum that is added is 100:0.1～0.5.
Preferably, the difference when reconstituted tobacoo coating fluid and the density that reclaims liquid is 0.05～0.1g/cm
2The time, recovery liquid is 100:1.0～2.0 with the part by weight of the sorbierite that is added, and recovery liquid is 100:1.0～2.0 with the part by weight of the potassium citrate that is added, and recovery liquid and the guar gum ratio that is added are 100:0.5～1.0.
The present invention compares with existing reconstituted tobacoo coating fluid recovery and utilization technology, has the following advantages:
1. the recycling of reconstituted tobacoo coating fluid is technological among the present invention; Can not cause the polysaccharide macromolecular (Main Ingredients and Appearance) that contains in the coating fluid and the loss of little molecules (causing fragrant composition) such as alcohols, aldehydes and ketone, therefore can not influence reconstituted tobacoo coating fluid quality and reconstituted tobacoo and inhale flavor.
2. the present invention utilizes multistage filtering equipment, can carry out high efficiency filter to the coating fluid that reclaims and handle, and removes tobacco disintegrating slag and baccy fiber, can not cause the obstruction of filter screen.
3. the present invention adopts film processing system, and can remove on the one hand influence reconstituted tobacoo and inhale the protein of distinguishing the flavor of, and can remove the aged substance in the recovery liquid on the other hand, like the pigment crystallite of gathering etc., can further purify recovery liquid.
4. the present invention adds sorbierite, potassium citrate and guar gum again in through the recovery liquid behind multistage filtering equipment and the film processing system, can avoid reconstituted tobacoo coating fluid quality to change.
