Embodiment 1

[0036] Embodiment 1. In this embodiment, a certain cigarette specification A is taken as an example to measure the blending uniformity of shredded tobacco. The specific operation includes the following steps:

[0037] (1) Sampling and pretreatment of cut tobacco blending samples

[0038] In the production time of a batch, take a sample at the cross-section of the vibrating groove at the flavoring outlet of blended shredded tobacco, take a sample every 1 hour, take a total of 5 samples, each sampling 20g, each time as a sample; The samples were respectively placed in a constant temperature and humidity environment at (22±1)°C and a relative humidity of (60±2)% to equilibrate for 48 hours before use.

[0039] (2), thermogravimetric analysis test of blended shredded tobacco sample

[0040] Grind the balanced blended cut tobacco sample through a 40-mesh sieve, weigh (10±1) mg of the sample, and place it in an alumina crucible of a thermogravimetric analyzer for thermal analysis t...

Embodiment 2

[0052] Embodiment 2. In this embodiment, a certain cigarette specification B is taken as an example to measure the blending uniformity of shredded tobacco. The specific operation includes the following steps:

[0053] (1) Sampling and pretreatment of cut tobacco blending samples

[0054] In the production time of a batch, take a sample at the cross-section of the vibrating groove at the flavoring outlet of blended shredded tobacco, take a sample every 1 hour, take a total of 5 samples, each sampling 20g, each time as a sample; The samples were placed in a constant temperature and humidity environment at (22±1)°C and a relative humidity of (60±2)% to equilibrate for 48 hours for later use.

[0055] (2), thermogravimetric analysis test of blended shredded tobacco sample

[0056] Grind the balanced blended cut tobacco sample through a 40-mesh sieve, weigh (10±1) mg of the sample, and place it in an alumina crucible of a thermogravimetric analyzer for thermal analysis testing. O...

Abstract

The invention discloses a method for measuring the blending uniformity of cigarette cut tobacco. The method is characterized by comprising the following steps: within the production time of one batch,taking flavored blended cut tobacco to carry out thermal weight loss testing five times at same intervals, calculating the similarity between every two obtained sample thermal weight loss TG curves and the variable coefficient between the similarities, and thus measuring the blending uniformity of cigarette cut tobacco. A thermal gravimetric analyzer is creatively used for the measurement of theblending uniformity of cigarette cut tobacco, the used equipment and operation treatment are simple, and neither tracer nor chemical reagent is needed; the quantity of the required sample in small; the method is quantitatively described and objective and accurate in experimental result; according to method principle, the method is applicable for any blending system.

Description

technical field [0001] The invention relates to a method for measuring blending uniformity of shredded tobacco in cigarettes, belonging to the technical field of tobacco processing. Background technique [0002] In the cigarette production process, blending and flavoring of shredded tobacco is an important process in the cigarette shredding process. The shredded leaves, expanded shreds and shredded stems are evenly blended in a certain proportion, and then delivered to the cigarette rolling link after passing through the flavoring drum. The uniformity of shredded tobacco blending directly affects the stability of physical indicators, smoke characteristics and sensory quality of cigarette products. Therefore, establishing a method that can objectively and accurately measure the blending uniformity of shredded tobacco is of great significance for maintaining and improving the quality of cigarette products. [0003] At present, the method of determining the blending ratio of v...
