Embodiment 1

[0016] Embodiment 1: cigarette specification A

[0017] In the silk-making process of cigarette specification A, 3 batches of silk-making samples are randomly taken, and according to the target value of amino acid content in pure silk, use the formula Y=0.0003t 2 -0.2149t+40.156 Calculate the temperature t (unit: ℃), which is the cylinder wall temperature to be determined online. The results are shown in Table 1 below:

[0018] Table 1 Target value of amino acid content in pure silk of cigarette specification A and tube wall temperature

[0019]

[0020] 【Note】In the table, the raw material value of amino acid content (mg / g) is the value of shredded tobacco before drum drying. The target value of amino acid content (mg / g) is the set value Y of shredded tobacco after drum drying. The actual value of amino acid (mg / g) is the actual measured value of shredded tobacco after being processed at the drum wall temperature t. The cylinder wall temperature t (°C) is based on the ...

Embodiment 2

[0022] Embodiment 2: cigarette specification B

[0023] In the silk-making process of cigarette specification B, two batches of silk-making samples are randomly taken, and according to the target value of amino acid content in pure silk, use the formula Y=0.0003t 2 -0.2149t+40.156 Calculate the temperature t (unit: ℃), which is the cylinder wall temperature to be determined online. The results are shown in Table 2 below:

[0024] Table 2 Target value of amino acid content in cigarette specification B pure silk and tube wall temperature

[0025]

[0026] It can be seen from Table 2 that after processing, the error between the actual value and the calculated value of the amino acid in shredded tobacco is not more than 7.36%. It can be seen that, with this Y=0.0003t 2 -0.2149t+40.156 The method of determining the processing temperature of the drum wall is simple and reliable. Then the processed shredded tobacco is made into cigarettes, and the industrial sensory evaluation...

Embodiment 3

[0027] Example 3: Cigarette Specification C

[0028] In the silk-making process of cigarette specification C, 4 batches of silk-making samples are randomly taken, and according to the target value of amino acid content in pure silk, use the formula Y=0.0003t 2 -0.2149t+40.156 Calculate the temperature t (unit: ℃), which is the cylinder wall temperature to be determined online. The results are shown in Table 3 below:

[0029] Table 3 Target value of amino acid content in cigarette specification C pure silk and tube wall temperature

[0030]

[0031] It can be seen from Table 3 that after processing, the error between the actual value and the calculated value of the amino acid in shredded tobacco is not more than 4.43%. It can be seen that, with this Y=0.0003t 2 -0.2149t+40.156 determines that the drum wall processing temperature (calculated value) is close to the actual set value. Then the processed shredded tobacco is made into cigarettes, and the industrial sensory eva...

Abstract

The invention discloses an online method for determining the tube wall temperature based on the amino acid content in shredded tobacco, which comprises the following steps: in the drum drying process, according to the target value Y (unit: mg / g) of the amino acid content in pure shredded tobacco, According to the formula Y=0.0003t 2 ‑0.2149t+40.156 Calculate the temperature t (unit: ℃), which is the cylinder wall temperature to be determined online. The method of the invention has the characteristics of simplicity, speed and accuracy.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for quickly determining the tube wall temperature in the drum shred drying process on-line based on the content of amino acids in shredded tobacco in the shredded cigarette process. Background technique [0002] The sensory characteristics of smoke are inseparable from the types and dominant ranges of chemical components in shredded tobacco. Amino acid is not only the main component of tobacco and its products, but also an important substrate for Maillard reaction. Certain amino acids such as phenylalanine can also be decomposed into flavor compounds such as benzyl alcohol and phenylethyl alcohol. The right amount of amino acid helps to improve the strength of the smoke and increase the fullness. If the amino acid content is too high, the smoke will be pungent, bitter and irritating, because the amino acid generates NH during the combustion process. 3 And o...
