Description
Technical field
The invention belongs to tobacco manufacturing technology field, be specifically related to a kind of tobacco extract method for concentration.
Background technology
Domestic papermaking-method reconstituted tobaccos normally adopts two-step method to produce, first adopt solvent that tobacco effective ingredient is fully soaked out, after again tobacco extract is concentrated, be backfilling on tobacco substrate the processes such as its production critical process comprises extraction, concentrates, manufactures paper with pulp, coating.In tobacco extract, conventionally contain the macromolecular substances such as a certain amount of protein, pectic substance, cellulose, hemicellulose, these compositions are generally present in extract admittedly to hang the form of thing, only separate these admittedly outstanding thing guarantee product qualities.In Chinese patent ZL200910063930.0 " comprehensive impurity new technology and the impurity removed system of tobacco sheet material extract ", adopt flocculation-supercentrifugal process to process tobacco extraction liquid, effectively improved papermaking-method reconstituted tobaccos product quality.At present in papermaking-method reconstituted tobaccos industry, concentrator is normally used for reference the multiple-effect vacuum concentration systems of pharmacy and food service industry use, complexity due to tobacco composition, concentration process exists that efficiency is low, heating tank inwall is easily tied the problems such as trowel used for plastering, as too low in thickening temperature, concentration time can be oversize, affects thickening efficiency; If but excess Temperature, the lower boiling aroma component of part can volatilize, and concentrate can form incrustation and affect heat transfer efficiency on heating surface.The method that solves at present concentrator scale problems has the methods such as the scale removal of the high-pressure water jet of employing, mechanical descaling, and these methods not only scale removal are not thorough, and waste time and energy.
Summary of the invention
The object of the invention is for above-mentioned defect, provide a kind of thickening efficiency high, and the tobacco extract method for concentration of the thorough scale removal of energy.
Above-mentioned purpose is achieved through the following technical solutions:
A method for concentration, comprises the following steps:
1) to the S-2 type absorptive clarificant that adds by weight 0.3～0.5% in tobacco extract, react 10～30 minutes separated by butterfly seperator, collect tobacco extract;
2) tobacco extract after separation is preheating to 40～60 ℃;
3) tobacco extract after preheating is pumped in the heating tank that outer wall arranges ultrasonic transmitter, carry out Vacuum Concentration.
Preferably: described S-2 type absorptive clarificant is 0.4% of tobacco extract weight.
Preferably: the ultrasonic frequency of described ultrasonic transmitter is 20～100KHz.
The better technical scheme of the present invention is that it adopts continuous concentration device to carry out Vacuum Concentration, described continuous concentration device comprises disk centrifuge, preheating can, pump, heating tank and vacuum chamber, the discharging opening of described disk centrifuge is connected with the import of preheating can, the discharging opening of preheating can is connected with the charging aperture of pump, the discharging opening of pump is connected with the charging aperture of heating tank, described heating tank and vacuum chamber are connected, it also comprises ultrasonic transmitter, and described ultrasonic transmitter is arranged on heating tank outer wall.
The ultrasonic frequency of described ultrasonic transmitter is 20～100KHz.
First the present invention adds S-2 type absorptive clarificant to carry out effectively separated removal to macromolecular substances such as the pectic substance in tobacco extract, protein, cellulose, hemicelluloses, avoids causing extract be heated excessively sex change, caking, coking because of it; Then before concentrated, extract is carried out to the pre-heat treatment, dwindle extract and the temperature difference that heats tank skin, can further prevent that on the one hand extract is at heating tubulation inwall knot trowel used for plastering, can prevent from the other hand that lower boiling material from acutely seething with excitement to form unsettled foam and taken away by steam, reduce product loss; Finally at heating tank outer wall, ultrasonic transmitter is set again, utilizes hyperacoustic vibration and the microjet effect, cavitation and the mechanism that form, can not only suppress the growth of dirty particle; reduce and shut down the scale removal time; and can improve heat transfer efficiency, and reduce thickening temperature, improve thickening efficiency.
The present invention can not only improve the concentrated quality of tobacco extract and efficiency, can also suppress and remove the growth of dirty particle, thereby reduces labor intensity in extension device service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of tobacco extract enrichment facility of the present invention.
In figure: 1-disk centrifuge, 2-preheating can, 3-pump, 4-heating tank, 5-vacuum chamber, 6-ultrasonic transmitter.
