Description

Analytical method for failure strength of flavor capsules for cigarette filters

technical field

The invention relates to a method for analyzing the breaking strength of essence capsule materials for cigarette filters, and belongs to the field of material testing methods.

Background technique

The development of cigarette products with low tar and low harm is the general trend. However, when the tar is reduced in cigarettes, the smoke taste will also be weak and the smoke flavor will be insufficient. Therefore, it is bound to put forward higher requirements for cigarette flavoring. There are many ways to add aroma, such as directly adding to shredded tobacco, or adding to the filter, which plays different roles in smoking, and adding aroma to the filter has the following advantages: ①The temperature in the filter is lower , the essence is not easy to volatilize, and the ingredients will not change, which can ensure the pure flavor of cigarettes; ② Add essence to the filter tip, which is closer to the mouth, and the filtering effect is small, which can make full use of the essence. Among them, the essence capsule filter can not only prevent the volatilization and loss of fragrance before smoking, but also prevent the perishable and highly sensitive fragrance from being affected by external factors after capsules are encapsulated. , improved storage stability. Therefore, many brands of cigarettes at home and abroad have applied flavor capsule filters and obtained market approval.

Destruction strength is one of the most important characteristic indicators of flavor capsule materials, and its characteristic indicators directly affect the filter rod molding and consumer consumption experience. If the destructive strength is too small, the capsule will be easily damaged during the filter rod forming process, which will pollute the forming equipment and affect the effective operation rate of the filter rod forming. Moreover, the consumer groups facing cigarettes include people of different genders and ages. If the damage is too strong, it will be difficult for consumer groups such as women and the elderly to squeeze the capsules and smoke cigarettes, which will directly affect consumers' consumption experience. . Flavor capsule filters have not been used in domestic brand cigarettes for a long time. At present, there is no standard analysis method for capsule failure strength in the tobacco industry. This invention establishes a more scientific and reasonable analysis of the failure strength of flavor capsule materials through the research of detection methods, the introduction of analysis device components and technological transformation. method.

There is a groove for placing essence capsules on the placing table, and the diameter of the groove is 0.5-1mm;

Destruction strength detection probe moving speed: 0.3-0.8mm/s;

The qualified detection limit of the test software on the computer is set at 0-30 N;

2. Specific method steps for measuring the failure strength of tobacco flavor capsule materials

(1) The balance between the sample to be tested and the testing instrument

A. Each batch of flavor capsule material samples to be inspected must be balanced by constant temperature and humidity in the testing laboratory for 24 hours. (Temperature 22°C±2°C; Humidity: 60.0%RH±5%RH)

B. The storage and operating environment of the testing instrument must be controlled by constant temperature and humidity. (Temperature: 22°C±2°C; Humidity: 60.0%RH±5%RH) If you are not in the test environment, you should stop the test. (except for drying oven and some measuring instruments)

(2) Power-on preheating and measurement

A. After a long shutdown and restart of the testing instruments, the electronic components need to be preheated to obtain accurate measurement results. Generally, it is required to connect to the AC power supply for at least 30 minutes, or after a long period of power loss.

B. Install the test software (TextExpert test software) to avoid reducing the performance of the instrument due to software problems.

C. First check the push-pull tester and the computer to ensure normal connection; then turn on the power of the push-pull tester and turn it on, and then turn on the computer; warm up for at least 30 minutes after turning on the machine, and start testing after the instrument reaches stability;

D. Double-click the test software on the computer to start the measurement, control the detection probe to move down until the detection pressure head touches the essence capsule to be tested, and continue to press down until the essence capsule is squeezed. At this time, the downward pressure reaches the peak value; after that, in the software The crushing strength value of the essence capsule to be tested is automatically obtained on the interface;

(3) Turn off the power of the instrument and clean the workbench.

(4) Maintenance

A. Prohibit the use of metal, sharp objects, or brutal operation of detection equipment.

B. After each use of the testing instrument, it is necessary to use special cleaning items to maintain and clean the testing instrument.

C. Professional maintenance is required every week.

In the present embodiment, the above test parameters and test steps are adopted, and 4 batches of essence capsules (20 in each batch, spherical, 2-5 mm in diameter) from different origins are subjected to the breaking strength test, and the results are shown in Table 1:

Table 1 Destruction strength test data of flavor capsules

It can be seen from the above test data that there are obvious differences in the test data of the damage strength of flavor capsules from different origins. If the damage strength is too small, it will cause a large number of flavor capsules to break due to production contact friction during the production process, resulting in environmental pollution and environmental pollution. Unqualified filter rod products will affect the effective operation rate of filter rod forming. However, if the destruction intensity is too large, it is difficult for consumer groups such as women and the elderly to pinch the capsules to smoke cigarettes, which directly affects consumers' consumption experience.

In addition, the SD values of the failure strength of flavor capsules from different origins are also significantly different, indicating that there are obvious differences in the stability of the failure strength of flavor capsules from different origins, which is also an important basis for analyzing and understanding the quality stability of flavor capsule materials.

Since the essence capsule filter rod is an emerging special filter rod product at home and abroad, due to the importance of the essence capsule damage strength index, a detection method for the essence capsule damage strength is studied to promote the production quality and batch production efficiency of the capsule filter rod.
