Problems solved by technology

However, this invention patent is only aimed at the anticorrosion of white water produced by papermaking reconstituted tobacco leaves. Bacteria agent for auxiliary antisepsis, improper selection of bacteriostatic agent type or dosage will have a certain impact on the sensory quality of reconstituted tobacco leaves

Embodiment 1

[0027] A method for maintaining the freshness of materials in a papermaking reconstituted tobacco leaf production system, such as figure 1 shown, including the following steps:

[0028] (1) The tobacco stem raw materials used for the production of reconstituted tobacco leaves by the papermaking method enter the stem washing process after the raw material pretreatment section, and are treated in hot water at 50°C for 5 minutes, and the solid and liquid are separated. The powder is mixed in a high-consistency hydraulic pulper to complete the primary water extraction; the primary water extraction concentration is 15% (that is, the solid content is 15wt%, the same below), the temperature is 70 ° C, and the time is 20min; At the same time of extraction, the primary extract was sterilized online under the condition of 700W by microwave sterilizer for 5 minutes in the high-concentration hydraulic pulper;

[0029] (2) The material after the first-level extraction that step (1) obtains ...

Embodiment 2

[0038] A method for maintaining the freshness of materials in a papermaking reconstituted tobacco leaf production system, such as figure 1 shown, including the following steps:

[0039] (1) The tobacco stem raw materials used in the production of reconstituted tobacco leaves by the papermaking method enter the stem washing process after the raw material pretreatment section, and are treated in hot water at 60°C for 3 minutes, and the solid and liquid are separated. The powder is mixed in a high-concentration hydraulic pulper to complete the primary water extraction; the primary water extraction concentration is 15% (that is, the solid content is 15wt%, the same below), the temperature is 70 ° C, and the time is 25min; At the same time of extraction, in the high-concentration hydraulic pulper, the primary extract was sterilized online for 5 minutes with a microwave sterilizer 700W;

[0040] (2) The material after the primary extraction obtained in step (1) is subjected to soli...

Embodiment 3

[0050] Take 1000g of the material in the high-consistency hydraulic pulper of the reconstituted tobacco production line of the papermaking method (that is, the primary extraction material, which is a mixture of reconstituted tobacco stems and tobacco powder) and divide it into 4 groups, each group 250g, put it in four 500ml extinguished Bacteria beakers, marked as A control, A experiment, B control, B experiment. Detect the initial total number of colonies in the A control sample, place the A experiment in a laboratory microwave sterilizer at a power of 700W, take it out after 5 minutes of treatment, detect the initial total number of colonies in the A test sample after the treatment, and compare the A control with the microwave The A test samples treated by the sterilizer were uniformly stirred at 30-40°C at room temperature (the stirring rotor was sterilized at high temperature); the B control and B experiments were heated to 70°C in a constant temperature water bath, and the...

Abstract

The invention provides a method for maintaining freshness of materials of a system for producing reconstituted tobaccos by a paper-making process. With the aid of the combination of one or two of means such as microwave, ultrasonic wave, ultraviolet and high temperature, the method mainly comprises the steps of carrying out online physical sterilization treatment on an extracting solution and an extracted material, finished slurry, slurry washing liquid, foul condensate and clear water; and setting a high-concentration aquapulper, a slurry forming pond, a diluting water tank and a clear watercollecting tank as treatment points. After being subjected to online physical sterilization treatment, the extracting solution and the extracted material, the finished slurry, the foul condensate, theslurry washing liquid and the clear water can separately retained for 24 h, 26 h, 192 h and 240 h or above, products and corresponding fresh samples of the reconstituted tobaccos do not have odors bysensory contrast, and the total number of colonies is smaller than the corresponding critical value of the total number of colonies and the total number of colonies of smelly samples which are not subjected to online physical sterilization. Chemical additives are not introduced in the process, the method is simple and convenient to operate and high in safety, and the quality of reconstituted tobacco products and the stability of production and running are ensured.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco production, in particular to a method for maintaining the freshness of materials in a papermaking reconstituted tobacco production system. technical background [0002] The reconstituted tobacco leaf of the papermaking method is to use tobacco stems, tobacco powder and other raw materials to make sheets with properties close to or even better than natural tobacco leaves. The tobacco raw materials are first extracted with water, and the dry materials are made into slurry after extraction to form a sheet base; the extract is purified. , Concentrated and flavored to form a coating liquid and back-coated on the film base to form a finished reconstituted tobacco leaf. [0003] Paper-making reconstituted tobacco leaves are rich in glucose, fructose, proline, protein and other carbon sources and nitrogen sources required for the growth and reproduction of microorganisms. Therefore, spoilage...
