Problems solved by technology

[0009] In order to solve the problems of poor tobacco stem expansion effect, low yield and poor quality of cut stems in the existing production of microwave-expanded cut stems, the present invention provides a method for improving the expansion effect of microwave-expanded cut tobacco stems. Add ammonium carbonate or ammonium bicarbonate to the medium, control the storage conditions to make it penetrate into the core of the tobacco stem, and expand the tobacco stem by 3-5 times under low power. There is no carbonization and ignition during the expansion process, and the obtained microwave Expanded cut stems have good draw quality

Embodiment 1

[0024] A method for improving the expansion effect of microwave-expanded tobacco stems is as follows:

[0025] (1) Screening of tobacco stems: 300 kg of upper stems of Honghe K326 are screened through a vibrating screen (the aperture of the screen is 5 mm×25 mm, and the mesh is a waist-shaped hole), and 212 kg of tobacco stems are screened.

[0026] (2) Stem soaking: put the tobacco stems screened in step (1) into water added with ammonium carbonate or ammonium bicarbonate and soak for 1 min, wherein the water temperature is 20°C, and the concentration of ammonium carbonate or ammonium bicarbonate aqueous solution is 1wt.%.

[0027] (3) Stem storage: store the tobacco stem impregnated in step (2) at 20°C for 1 hour, the penetration rate of the tobacco stem is 98.4%, and the moisture content of the tobacco stem is 22.4%;

[0028] (4) Air-drying: the tobacco stems stored in step (3) were air-dried at 30°C for 4 hours, and the moisture content of the tobacco stems was 11.2%.

Abstract

The invention relates to a method for improving the expansion effect of microwave expansion tobacco stems, and belongs to the technical field of tobacco stem processing. The process method includes the steps of tobacco stem screening, stem soaking, stem storing, air drying and microwave expansion. In the tobacco stem pre-processing process, ammonium carbonate or ammonium bicarbonate is added; the ammonium carbonate or the ammonium bicarbonate is soaked into cores of the tobacco stems by controlling the stem storing condition; at the lower power, the tobacco stems are expanded by 3-5 times; in this way, the acute degree of changes of chemical contents and aroma components of the tobacco stems is reduced; losses of natural tobacco incense of tobaccos are reduced; carbonization and fire striking are avoided; the quality of microwave expansion stem strips is improved; and meanwhile energy resources are saved.

Description

Technical field: [0001] The invention relates to a method for improving the expansion effect of microwave-expanded tobacco stems, and belongs to the technical field of tobacco stem processing. Background technique: [0002] Tobacco stems account for about 20% to 30% of the total weight of tobacco leaves, have a similar chemical composition to tobacco leaves, and can improve the structure of cigarettes, reduce costs and reduce tar. They have always been an important part of cigarette leaves. However, because tobacco stems contain more cell wall substances such as cellulose, hemicellulose, lignin, and pectin than tobacco leaves, it is easy to produce green miscellaneous gas, woody gas, and burning sensation when burning, which have a negative impact on smoking quality. Factors that affect the use range and addition ratio of tobacco stems in the cigarette leaf group. [0003] The microwave expansion and filamentary forming technology of tobacco stems is an emerging new technol...
