Embodiment 1

[0024] A method for reducing the viscosity of reconstituted tobacco leaf coating solution, the steps are as follows:

[0025] 1) Add 850Kg of water to the chelating agent dissolving tank, set the heating temperature to 35°C, the stirrer speed to 300r / min, and turn on the stirrer;

[0026] 2) Slowly and evenly add 150Kg sodium hexametaphosphate to the chelating agent dissolving tank, and stir for 15 minutes after adding;

[0027] 3) Pour the coating solution into the coating solution tank in batches, and then add the flavors and fragrances required by the formula and heat to 50°C; because in the different formulas of each reconstituted tobacco leaf, the flavors and fragrances used are different in amount and type. are not the same, so just add as needed.

[0028] 4) Add sodium hexametaphosphate accounting for 0.1% of the weight of the coating solution under the conditions of step 3);

[0029] 5) Put the coating liquid in step 4) into the coating liquid supply tank after being...

[0035] A method for reducing the viscosity of reconstituted tobacco leaf coating solution, the steps are as follows:

[0036] 1) Add 800Kg of water to the chelating agent dissolving tank, set the heating temperature to 40°C, the stirrer speed to 600r / min, and turn on the stirrer;

[0037] 2) Slowly and evenly add 200Kg sodium hexametaphosphate to the chelating agent dissolving tank, and stir for 20 minutes after adding;

[0038] 3) Pour the coating liquid into the coating liquid tank in batches, and then add the flavors and fragrances required by the formula and heat to 50°C; because in the different formulas of each reconstituted tobacco leaf, the flavors and fragrances used are different in amount and type. are not the same, so just add as needed.

[0039] 4) Add sodium hexametaphosphate accounting for 0.5% of the weight of the coating solution under the conditions of step 3);

[0046] A method for reducing the viscosity of reconstituted tobacco leaf coating solution, the steps are as follows:

[0047] 1) Add 900Kg of water to the chelating agent dissolving tank, set the heating temperature to 35°C, the stirrer speed to 350r / min, and turn on the stirrer;

[0048] 2) Slowly and evenly add 100Kg sodium hexametaphosphate to the chelating agent dissolving tank, and stir for 15 minutes after adding;

[0049] 3) Pour the coating liquid into the coating liquid tank in batches, and then add the flavors and fragrances required by the formula and heat to 50°C; because in the different formulas of each reconstituted tobacco leaf, the flavors and fragrances used are different in amount and type. are not the same, so just add as needed.

[0050] 4) Add sodium hexametaphosphate accounting for 0.2% of the weight of the coating solution under the conditions of step 3);

Abstract

The invention relates to a method for reducing the viscosity of a reconstituted tobacco coating solution. By adding a calcium and magnesium ion chelating agent into the coating solution, the reactionof calcium and magnesium ions with ions such as malic acid radicals and citric acid radicals is blocked; the generation of sparingly soluble and insoluble calcium magnesium salt particles is reduced;through a high pressure homogenizer, the particle diameter of suspended particles becomes small, so that the content of suspended matters in the coating solution is reduced; the viscosity of the coating solution is reduced; and the permeability of the coating solution is effectively improved. Through detection, after the treatment through chelating agent addition in the technical scheme, the content of the suspended matters in the coating solution is reduced from 2.0 to 4.0 percent of the existing process to a value below 1.5 percent; the content of suspended matters in a backflow solution canbe reduced from a value higher than 4.0 to 6.0 percent to a value below 2.5 percent; the viscosity of the coating solution is reduced by 40 percent or higher; the viscosity of the backflow solution is reduced by 50 percent or higher; the permeability of the coating solution is effectively improved; the physical performance of produced tobacco sheets is improved; and the occurrence of phenomena ofwhite cores and sheet sticking of products is reduced.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves by a papermaking method, and in particular relates to a method for reducing the viscosity of a coating liquid for reconstituted tobacco leaves. Background technique [0002] The papermaking method of reconstituted tobacco leaves, commonly known as tobacco flakes, is to use tobacco waste such as tobacco stems, tobacco powder and chips as the main raw materials, impregnate the tobacco raw materials with water, and then separate the water-soluble and insoluble substances in the tobacco from solid-liquid. Equipment and technology, insoluble matter such as tobacco fiber is dispersed in water and then passed through a paper machine to form a fiber sheet. At the same time, the water-soluble matter is concentrated and coated back on the sheet. After drying, it is reconstituted tobacco leaves by papermaking. [0003] The coating solution contains a large amount of macromolecular substa...
