Description

Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a retractable sampling container for evaluating the aroma quality of essences. Background Art

[0002] Tobacco flavors play a role in giving tobacco products aroma characteristics, blending tobacco flavors, improving smoking quality, and improving processing performance. They are indispensable additives in the modern cigarette industry. Therefore, it is particularly important to control the quality of tobacco flavors. Among them, general evaluation of the aroma quality of tobacco flavors, judging whether its aroma quality is consistent with the standard sample and whether it has changed, are important quality control indicators for tobacco flavors.

[0003] In the prior art, the general evaluation of aroma quality of tobacco flavors is carried out according to the standard of YC / T 145.6 "General Evaluation Method for Aroma Quality of Tobacco Flavors". The specific operation method is to put equal amounts of test sample and standard sample in the same clean and odorless sample bottles, and then use aroma identification paper to dip about 1-2cm of the test sample and standard sample in the container, and the evaluator will use the sense of smell to judge the aroma quality (including aroma type, aroma concentration, strength, persistence, and impurities) to determine whether the aroma quality of the test sample has changed compared with the standard sample.

[0004] It can be seen that the general evaluation of the aroma quality of tobacco flavors first requires sampling the incoming samples to obtain test samples, and then the test samples need to be dipped into the fragrance paper, and then the natural volatilization of the tobacco flavors on the fragrance paper is used to complete the evaluation through the olfactory discrimination of the evaluator. On the one hand, tobacco flavors are generally liquids and are packaged in 25 kg or larger plastic barrels. In order to ensure the representativeness and uniformity of the sampling, the samplers need to shake the packaging barrels, and then pour the samples from the packaging barrels or take out the samples with sampling containers. The whole sampling process is cumbersome and laborious; on the other hand, after the sample sampling and evaluation is completed, the samples need to be destroyed or other harmless treatments, which will cause waste and pollution to the environment.

[0030] As shown in the figure, the embodiment of the utility model provides a retractable sampling container for flavor aroma quality assessment, comprising:

[0031] A retractable container 1;

[0032] A first valve 2 and a second valve 3 are respectively connected to the container 1.

[0033] The present application provides a retractable sampling container for flavor aroma quality assessment, a retractable container 1; a first valve 2 and a second valve 3 respectively connected to the container 1, which utilize the expansion and contraction of the container 1 to change its internal volume, thereby achieving the inhalation of external gas (such as the aroma to be assessed) or the discharge of internal gas. By using the retractable sampling container provided by the present application, there is no need to sample the liquid of the tobacco flavor, and gas sampling can be performed directly, which is simple to sample, and there is no need to process the liquid sample after the test is completed; after one sampling, repeated evaluations can be performed, and it is easy to clean when it needs to be reused. In addition, the retractable sampling container provided by the present application can be folded to a minimum volume when not in use, and does not take up space.

[0034] Specifically, the method for using the retractable sampling container provided in this application is as follows:

[0035] Compressing container 1 to its minimum volume;

[0036] Open the lid of the tobacco flavor packaging barrel, extend one of the valves of the retractable sampling container into the upper space in the tobacco flavor packaging barrel, but do not touch the tobacco flavor; open the valve, stretch the container 1, and use the negative pressure generated during the stretching process of the container 1 to automatically inhale the gas in the upper space of the tobacco flavor packaging barrel. After the container 1 is partially or completely stretched, remove the retractable sampling container, close the valve opened during the sampling process, and the sampling is completed. When it is necessary to conduct a general assessment of the aroma quality of tobacco flavors, open one of the valves, compress the container 1 to make the gas overflow, and then smell it and judge the aroma quality. The operation is simple.

[0037] The applicant found that after tobacco flavoring is added to the packaging barrel, the tobacco flavoring liquid will not be filled up, and there will be a certain amount of space left in the upper layer. During transportation and storage, the volatile components in the tobacco flavoring will fully evaporate into the upper space in the packaging barrel. The general evaluation of aroma quality in this field adopts YC / T 145.6 "General Evaluation Method for Aroma Quality of Tobacco Flavoring", which also uses fragrance paper to absorb the liquid sample, and the evaluator uses the sense of smell to judge the aroma quality, and also smells the aroma components volatilized from the liquid. Therefore, directly taking the gas in the upper space in the tobacco flavoring packaging barrel can fully represent the aroma of the tobacco flavor, and the same olfactory evaluation is performed, and the results obtained can also accurately evaluate the aroma quality of the tobacco flavor. Therefore, based on a deep understanding of the principle of the general evaluation method for aroma quality of tobacco flavoring, this application provides a retractable sampling container for flavor aroma quality evaluation, which is particularly suitable for the quality evaluation of tobacco flavoring.

[0038] Preferably, the container 1 has two opposite end surfaces 11 and a telescopic side wall 12 located between the two end surfaces 11;

[0039] The first valve 2 and the second valve 3 are arranged on the end surface 11 .

[0040] The container 1 preferably includes two end surfaces 11 disposed opposite to each other, and a telescopic side wall 12 located between the two end surfaces 11. Both ends of the telescopic side wall 12 are respectively sealed and connected to the outer peripheral edges of the end surface 11, and together form a container 1 having a cavity inside. In addition, the first valve 2 and the second valve 3 that connect the internal space of the container 1 to the outside atmosphere are arranged on the end surface 11, so that the opening and closing of the valves and the contraction and expansion of the telescopic side wall 12 will not interfere with each other.

[0041] The shape of the end face 11 can be circular, and the telescopic side wall 12 and the two end faces 11 form a cylindrical shape; the shape of the end face 11 can also be any shape such as square, irregular shape, etc.

[0042] Preferably, the telescopic side wall 12 is corrugated.

[0043] Preferably, the telescopic side wall 12 is in a corrugated shape, and the internal volume of the container 1 is changed by the corrugations moving closer to or farther away from each other. The volume change is large, and the container can be used repeatedly.

[0044] Preferably, the first valve 2 is located on one end surface 11 , and the second valve 3 is located on the other end surface 11 .

[0045] The first valve 2 and the second valve 3 can be arranged on the same end surface 11 or on different end surfaces 11. For the convenience of cleaning and other operations, it is preferred that the first valve 2 is arranged on one end surface 11 and the second valve 3 is arranged on the other end surface 11.

[0046] Preferably, the container 1 is connected to the external atmosphere through the first pipeline 4 and the second pipeline 5.

[0047] The first valve 2 is disposed on the first pipeline 4 , and the second valve 3 is disposed on the second pipeline 5 .

[0048] Preferably, the container 1 is connected to the external atmosphere through the first pipeline 4 and the second pipeline 5, the first valve 2 is arranged on the first pipeline 4, and the second valve 3 is arranged on the second pipeline 5. The arrangement of the pipeline makes it easier to reach into the essence barrel for sampling.

[0049] The first pipeline 4 and the second pipeline 5 can be arranged at any position of the container 1. By arranging a hard support ring at the position where the pipeline contacts the container 1, it can be ensured that the pipeline is unobstructed when the container 1 is compressed and expanded. When the container 1 has a structure of an end surface 11 and a telescopic side wall 12, the first pipeline 4 and the second pipeline 5 are preferably arranged on the end surface 11.

[0050] Preferably, the second pipeline 5 is also provided with a retractable corrugated section.

[0051] It is more preferred to set the second pipeline 5 to be longer, and use the longer second pipeline 5 to extend into the barrel to avoid moving the heavy flavor barrel. It is also possible to sample the flavor with less or no moving of the retractable sampling container.

[0052] More preferably, the second pipeline 5 is also provided with a retractable corrugated section, which is more convenient for inserting into the essence barrel for sampling. The second valve 3 is arranged at a distance from the corrugated section to avoid the setting of the valve affecting the retraction of the corrugated section.

[0053] Preferably, the volume of the container 1 is 100-1000 ml.

[0054] Preferably, the volume of the container 1 is 500-800 ml.

[0055] The maximum volume of the container 1 is preferably 100-1000 ml, more preferably 500-800 ml, which can meet the requirements of sampling for one or more evaluations and is convenient for operators to carry, sample and perform other operations.

[0056] In the present application, the volume change of container 1 during one sampling can be determined based on the gas volume required for the assessment and the number of repetitions. Container 1 can be partially compressed, in which case the volume of gas inhaled is smaller than the capacity of container 1 ; or container 1 can be fully compressed, in which case the volume of gas inhaled is close to the capacity of container 1 .

[0057] Preferably, the container 1 is made of silicone.

[0058] The material of the container 1 is preferably silica gel, which is durable, low-cost, and will not have a negative impact on the aroma.

[0059] Example 1

[0060] A retractable sampling container for evaluating the aroma quality of an essence, comprising:

[0061] A retractable container 1; the container 1 has two opposite end surfaces 11, and a retractable side wall 12 located between the two end surfaces 11, and the retractable side wall 12 is corrugated;

[0062] The container 1 is connected to the external atmosphere through a first pipeline 4 and a second pipeline 5. The first pipeline 4 is located at one end surface 11, and the second pipeline 5 is located at another end surface 11. The first valve 2 is provided on the first pipeline 4, and the second valve 3 is provided on the second pipeline 5.

[0063] The container 1 has a capacity of 1000 ml and is made of silica gel.

[0064] The above-mentioned retractable sampling container was used to perform sampling and evaluation on the aroma quality of tobacco flavoring essence A. This essence is a brown transparent liquid. At 20 degrees Celsius, its relative density is 0.8168, and its refractive index is 1.3646. It has a spicy and fruity aroma. It is packaged in a 25L blue plastic barrel.

[0065] The assessment steps are as follows:

[0066] Open the first valve 2 and / or the second valve 3 to compress the container 1 to a minimum volume;

[0067] Open the lid of the tobacco flavor packaging barrel, extend the second pipeline 5 of the retractable sampling container into the upper space in the tobacco flavor packaging barrel, but do not touch the tobacco flavor; keep the second valve 3 open, close the first valve 2, stretch the container 1, and use the negative pressure generated during the stretching of the container 1 to automatically inhale the gas in the upper space in the tobacco flavor packaging barrel. After the container 1 is fully stretched, remove the above-mentioned retractable sampling container, close the second valve 3, and the sampling is completed.

[0068] After the 12 evaluators are ready for evaluation, they open the first valve 2 and / or the second valve 3 to compress the container 1 to allow gas to overflow. The evaluators judge the aroma quality of the overflowing gas by smell.

[0069] The standard samples were sampled in the same way, and the aroma quality of the escaped gas was judged by the evaluators using their sense of smell in the same way.

[0070] Example 2

[0071] Taking the general evaluation of the aroma quality of tobacco flavoring B as an example, this flavor is a brown viscous liquid. At 20 degrees Celsius, its relative density is 0.9349, and its refractive index is 1.5436. It has a sweet and roasted aroma. It is packaged in a 25L blue plastic barrel.

[0072] The above tobacco flavoring B and standard samples were evaluated using the same retractable sampling container and method as in Example 1, except that the second pipeline 5 of the retractable sampling container was provided with a retractable corrugated section.

[0073] The container and method of Example 1 were used to verify the rigid sampling container and the method of use for flavor aroma quality assessment of the present application, as follows:

[0074] The evaluation team is composed of 12 evaluators who are qualified to evaluate aroma quality. 12 groups of samples are prepared, each group of samples consists of 3 coded samples, of which two samples are the same and one sample is different: Code 1 is the incoming sample of flavoring essence A, and Code 2 is the standard sample of flavoring essence A. The codes of the 12 groups of samples are as follows: 211, 122, 112, 221, 121, 212, 211, 122, 112, 221, 121, 212. The three-point inspection method is used to assess whether the aroma quality (including fragrance type, aroma concentration, strength, persistence, and impurities) of the sample is consistent with that of the standard sample. The YC / T 145.6 scent paper dipping method and the container and method of Example 1 are used respectively, and each evaluator points out the single zero sample. The results of correctly pointing out the single zero sample are as follows:

[0075]

[0076] Check the significance table of binomial distribution in the appendix of YC / T 145.6 standard (α=5%). When there are 12 evaluators for the three-point test method, its critical value is 8. Both methods correctly point out that the number of single zero samples is 6, which is less than the critical value of 8. Therefore, at the 5% significance level, there is no significant difference between the incoming sample and the standard sample of flavoring essence A.

[0077] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
