Disclosed is a device and method for reducing combustion cone fallout propensity and stabilizing loss of tobacco from ends. Firstly, the right installation positioning hole is moved rightwards to extend the distance of the separation zone. Meanwhile, the vibration mechanism is redesigned so that it is enabled to move toward the lower right of the material groove body. Therefore, there is enough space to install the separation screen in the separation zone. Finally, the separation screen is installed. The tobacco scraps are separated out when they pass through the separation screen, thus reducing cone dropping when the cigarette burns, stabilizing the amount of dropping tobacco at the end, and improving the smoking experience and recognition of customers with regard to cigarette products.

The application discloses a method for testing the maximum ash column deviation of a cigarette. The cigarette is simulated to be smoked by a cigarette smoking device. The cigarette smoking device has three image collecting devices, and the interval angle between two adjacent image collecting devices is 120 degrees. At a smoking time t, the cigarette ash column picture is collected by the three image collecting devices, and then the maximum ash column deviation is calculated by using the collected cigarette ash column picture. According to the pixel color difference in the image, the cigarette positioning is obtained. The angle measurement method is used to measure the cigarette burning deviation observation angle and the cigarette ash column height of the three image collecting devices. The maximum cigarette ash column deviation is calculated by the height and the observation angle.

This invention provides a cigarette containing jasmine flower essential oil, belonging to the field of tobacco product technology. The cigarette filter includes a flavor capsule containing jasmine flower essential oil and a hollow slow-release device that encapsulates the flavor capsule. The hollow slow-release device has several through-holes on its outer periphery to release the aroma substances from the flavor capsule. The jasmine flower essential oil is prepared as follows: 1) Jasmine flower powder is soaked and stirred, then enzymatically hydrolyzed and filtered to obtain filtrate A and jasmine flower residue; 2) Filtrate A is obtained by microwave-assisted steam distillation to obtain a fraction; 3) The jasmine flower residue is extracted with an organic solvent and filtered to obtain filtrate B; 4) The fraction and filtrate B are combined, concentrated, and inactivated to obtain jasmine flower essential oil. The enzyme preparation is at least one of glucose isomerase, the non-specific enzyme streptavidin E, and bromelain. The enzyme preparation provided by this invention not only improves the essential oil extraction rate but also enhances the aroma; the slow-release device further prevents the essential oil from evaporating too quickly, ensuring a supply until the cigarette burns out.
