Abstract

The invention relates to a method utilizing the microwave technology to produce pure-tobacco stem reconstituted tobacco leaves. Air-dried tobacco stems are moistened by steam until the moisture content is 30 to 40 percent, meanwhile, the temperature is increased to 80DEG C to 90DEG C, and the tobacco stems are used as raw material; the raw material is then put into microwave equipment with the power of 60KW to 800KW, and is continuously processed under the technological condition of 130DEG C to 150DEG C, and the throughput of the raw material is 1kg/min to 1300kg/h; the microwave-processed raw material is then extracted with water, the solid-to-liquid ratio is controlled at 1:6 to 8 during extraction, the extraction temperature is 65DEG C to 70DEG C, and the extraction time is 20 to 40 minutes; finally, the obtained extract is concentrated and technologically prepared to serve as coating solution, the extracted solid matter is beaten and sheeted, the prepared coating solution is dip-coated on the sheets, and after drying, the pure-tobacco stem reconstituted tobacco leaves are produced. The method can utilize the microwave technology and adopt the cheap pure tobacco stems to produce the reconstituted tobacco leaves with little foreign gases and strong aroma.

Description

A kind of method of utilizing microwave technology to produce pure offal reconstituted tobacco

Technical field

The invention belongs to the papermaking-method reconstituted tobaccos production technical field.

Background technology

Domestic papermaking-method reconstituted tobaccos technology is started late, and realizes that industrialization is less than the time in 10 years, and because of it has wide application prospect to the consumption reduction of cigarette industry and the improvement of cigarette quality, development rapidly.The production method of present domestic papermaking-method reconstituted tobaccos; For using waste tobacco and waste tobacco stalk and other non-baccy fibers as mixed material; Solid content after concentrating through solvent extraction, extract and to do coating fluid, extracting utilize the making beating of papermaking ratio juris, the moulding of manufacturing paper with pulp, coating fluid return and be coated with, dry and production procedure such as cut, acquisition can supply the reconstituted tobacco of cigarette industry use.Quantity is more and waste tobacco stalk that price is relatively low; Because it can produce assorted gas such as xylon gas in combustion process; When causing prepared reconstituted tobacco to be applied in the cigarette, when suction, there are more unfavorable factors such as excitant, thereby influenced its prescription consumption in producing reconstituted tobacco.

Summary of the invention

The object of the invention provides a kind of microwave technology capable of using for the deficiency that solves the prior art existence just, adopts the method for the lower reconstituted tobacco that pure offal production impurity removal gas is little, fragrance is higher of price.

The objective of the invention is to realize through following technical scheme.

A kind of method of utilizing microwave technology to produce pure offal reconstituted tobacco, method step is following:

1. with air-dry offal through the moist steam humidification to moisture content 30%-40%, heat simultaneously to 80 ℃-90 ℃ as raw material;

2. raw material being sent into the microwave equipment that power is 60KW-800KW, is to carry out high temperature under 130 ℃-150 ℃ the process conditions to handle continuously in temperature, and raw material is 1kg/min-1300kg/h through amount;

3. the raw material water after the microwave treatment is once extracted, solid-to-liquid ratio is controlled to be 1 during extraction: 6-8, and extracting temperature is 65 ℃-70 ℃, extraction time 20min-40min;

4. the gained extract concentrates through technology and modulates as coating fluid, and sheet is copied in the solid content making beating after the extraction, and to copying on the sheet, oven dry obtains pure offal reconstituted tobacco with the coating fluid dip-coating of modulating;

According to the invention with extract concentrate and the method for carrying out the technology modulation to be said extracted liquid be concentrated into the 60%-70% of over dry raw material weight through vacuum, again through technology modulation such as food-grade toning and food-grade moist-keeping flavourings.

The present invention utilizes microwave technology, makes full use of the waste tobacco stalk that produces than processes such as waste tobacco obtains easily and price is lower cigarette redrying and production of cigarettes, the pure offal reconstituted tobacco that production can supply cigarette industry to use.

The pure offal reconstituted tobacco that adopts the present invention to make can increase its reconstituted tobacco prescription consumption in production of cigarettes, has promptly effectively utilized discarded originally tobacco stalk raw material, has practiced thrift resource, can reduce the cost of material of cigarette again, also can improve the suction quality of cigarette.

The present invention optimized in the existing papermaking-method reconstituted tobaccos production process feed intake, extract and stream such as send at technological process:

1. reduced the tobacco leaf treatment system in the existing papermaking-method reconstituted tobaccos production process;

2. tobacco leaf and the hybrid system of offal in the existing papermaking-method reconstituted tobaccos production process have been reduced;

3. since offal after microwave treatment, temperature improves, and has saved the energy consumption of extracting the water heating in the existing papermaking-method reconstituted tobaccos production process;

The raising of 4. pure tobacco stalk fibre intensity has reduced the isometric fiber consumption of softwood pulp.

Further set forth content of the present invention below in conjunction with Figure of description.
