2results about How to "The method is simple and efficient" patented technology

This invention relates to the field of tobacco processing technology, specifically a method for determining the penetration rate of exogenous additives in tobacco leaves, comprising the following steps: 1) tobacco leaf pretreatment; 2) sample loading of tobacco leaves and exogenous additives: tobacco leaves and exogenous additives are placed in two thin-film mixing tanks, one for experimental groups and one for control groups; 3) application of exogenous additives; 4) heat detection: a calorimeter is used to detect and record the heat changes throughout the entire process, including the application of the exogenous additives to the tobacco leaves, their penetration into the tobacco leaves, and their reaction with reactants in the lower tank after passing through the tobacco leaves; 5) calculation of the penetration rate. The advantages of this invention are: by accurately detecting the heat changes of exogenous additives during the penetration process in tobacco leaves, the penetration rate of tobacco leaves can be characterized in real time and dynamically. It is applicable to the detection of the penetration rate of different types of exogenous additives in tobacco leaves, has a wide range of applications, and is simple and efficient.

This invention discloses a pressure testing device, a tobacco slurry preparation system, and its applications. The pressure testing device includes a loading mechanism, an automatic pressing unit, a control system, and a pressure sensing mechanism. The loading mechanism contains loose tobacco material, which is pressed to form tobacco slurries. The automatic pressing unit is connected to the loading mechanism and is driven by the control system to press the loose tobacco material within the loading mechanism. The pressure sensing mechanism measures the pressure exerted on the loose tobacco material during the pressing process. Before preparing samples of loose tobacco with unknown properties, the pressure testing device is used to investigate the control parameters for the tobacco slurry preparation process. Experimental tobacco slurries are obtained by pressing the loose tobacco material using the pressure testing device to determine the sample preparation control parameters for achieving uniform density distribution of the material. Then, using the obtained sample preparation control parameters, a different preparation device is used to obtain tobacco slurries for measuring thermophysical parameters.
