Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing, in particular to a full-automatic rapid sweetness detector based on spectral technology. Background Art

[0002] In recent years, with the changing demographics of cigarette consumers, cigarettes containing sweetened tipping paper have become increasingly popular and accepted by consumers to enhance flavor and improve taste. Sweeteners are a type of food additive primarily used to impart a sweet taste to food. Tobacco companies flavor tipping paper by spraying sweeteners directly onto the paper, imparting a sweet taste. However, uneven spraying often results in significant sweetness variations between batches of tipping paper, impacting the quality and stability of cigarette products. Furthermore, excessive intake of non-sugar sweeteners can pose health risks and lead to a range of adverse reactions.

[0003] Currently, tobacco companies mostly rely on artificial taste tasting to determine sweetness differences, but this method is subject to significant individual variability and cannot accurately measure sweetness. While accurate, methods like chromatography and mass spectrometry measure the total sweetener content of the entire paper, failing to fully characterize the sweetness of the tipping paper surface. Furthermore, the testing process is time-consuming and costly, making large-scale batch testing on production lines unfeasible. Therefore, a fully automated testing instrument is urgently needed that can rapidly test large numbers of tipping paper samples on the production floor.

[0004] The existing standard method requires large-scale equipment detection, which is time-consuming, expensive, and cannot be used for batch detection. The near-infrared spectroscopy method has complex algorithm model maintenance and requires high professional skills. Therefore, we propose a fully automatic rapid sweetness detector based on spectral technology. Utility Model Content
