Tobacco leaf brittleness detection method

Abstract

The invention discloses a tobacco leaf brittleness detection method which comprises the following steps: A: clipping and cutting to-be-detected tobacco leaves; B: performing moisture equilibrium treatment on the clipped tobacco leaves; C: using the drying oven method to measure moisture in the tobacco leaves and tobacco shred after the moisture equilibrium treatment performed in step B, and recording; D: utilizing a texture analyzer and the TPA test to measure the texture properties of the tobacco leaves on the condition and reading the brittleness value A1; E: repeating step D for N-1 times, recording the brittleness value An every time, averaging the brittleness values of N times through the texture analyzer, so as to obtain the final brittleness value. According to the invention, the TA-XT2 texture analyzer is utilized, and the TPA classic evaluation method is adopted to evaluate the brittleness of tobacco leaves (shred), and the tobacco leaf brittleness detection method is established. The method is a beneficial supplementation for tobacco leaf physical property in the tobacco industry. With addition of the detection method, the external force received by the tobacco leaves during the processing process is known in a more comprehensive manner, so that the processing quality and the processing level can be improved easily.

Description

technical field [0001] The invention relates to the field of tobacco brittleness detection, in particular to a detection method for tobacco leaf brittleness. Background technique [0002] Tobacco is a fragile material, and it is inevitable that it will be shredded during processing. Excessive crushing will not only lead to a large amount of waste of tobacco raw materials and increase the cost of cigarette processing, but also directly affect the processing quality of tobacco leaves and cigarettes. The dust formed by tobacco crushing is also an important factor affecting the production environment. Tobacco will be subject to various mechanical forces during the processing process, such as "tearing and beating" in the process of leaf threshing and air separation, boxing of tobacco sheets after rebaking, slicing, shredding, and rolling in the process of silk making. The compression deformation during the manufacturing process, as well as the vibration and friction with the pip...

Problems solved by technology

At present, the tobacco industry mainly evaluates the toughness of tobacco leaves by testing tensile strength, elongation and other indicators, and then indirectly evaluates the processing resistance of tobacco. The longitudinal extension force, this detection method, to a certain extent, limits the research on the mechanical properties of tobacco and its application in actual production

However, no matter in the process of threshing and redrying or in the process of cigarette production, the tobacco leaves are subjected to various forces in the process of processing. Now the tobacco industry only studies the force of longitudinal extension, which is somewhat one-sided
