Description

Technical Field

[0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for determining a cigarette processing technology based on a large-scale technology concept. Background Art

[0002] The processing technology of cigarette manufacturing, starting from leaf threshing and redrying, involves the following process flows: leaf threshing and redrying process flow → tobacco sheet aging → tobacco shredding process flow → tobacco shredding process flow. Among them, the leaf threshing and redrying process flow mainly includes: material preparation → vacuum rehydration → sorting and selection → hot air moistening → leaf threshing and air separation → redrying → packaging process; the tobacco shredding process flow mainly includes: material preparation → vacuum rehydration → loose rehydration → leaf material addition → tobacco sheet storage → shredding → shredding → flavoring → tobacco shredding storage process.

[0003] In order to meet the specific requirements of production, tobacco materials have to go through many heat and moisture treatment processes in various links such as leaf threshing and re-baking, and silk making (such as tobacco strip re-baking, leaf loosening and moisture recovery, leaf silk drum drying and airflow drying, etc.). This heat and moisture treatment process has a significant impact on the physical and chemical aspects of cigarette raw materials. Because these processes use media such as steam, hot air and atomized water, which directly act on tobacco leaves or form a high temperature and high humidity environment, the tobacco leaves are heated and humidified or dehydrated in a relatively short period of time, and the heat and moisture treatment type of tobacco thermal transformation research occurs, which stimulates the chemical reaction of the aroma components in the tobacco leaves, and the volatile components are lost, which directly affects the sensory quality of the tobacco leaves. Summary of the invention

[0004] The purpose of the present invention is to provide a method for determining cigarette processing technology based on the concept of large-scale technology, so as to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

Y总For the silk making process;

[0010] S4. Carry out processing strength test on each heat treatment process to finally determine the processing strength of each heat treatment process.

[0011] Furthermore, the N heat treatment processes in step S1 include the vacuum moisture regain process, hot air leaf moistening process and re-roasting process in the leaf beating and re-roasting process, and the vacuum moisture regain process, loose moisture regain process and silk drying process in the silk making process.

[0012] Furthermore, the overall processing intensity in step S2 is to regard the tobacco material in different heat treatment processes as a whole, consider the heat and moisture processing parameters and processing intensity as a whole, and set an overall processing intensity that meets the requirements of the tobacco formula.

[0013] Furthermore, the overall processing intensity is determined based on the processing resistance of the incoming tobacco leaves and the processing targets determined by sensory evaluation.

[0014] Furthermore, the overall processing intensity decomposition in step S3 is set to be distributed in each heat treatment process by a high-first-low-later, low-first-high-later or uniform distribution idea.

[0015] Furthermore, Q X总 =Q X1 + Q X2 + Q X3 , where Q X1 Q is the processing strength of vacuum rehumidification process, X2 The processing strength of the hot air leaf moistening process, Q X3 It is the processing intensity of the redrying process;

[0016] Q Y总 =Q Y1 + Q Y2 + Q Y3 , where Q Y1 It is a vacuum rehumidification process, Q Y2 For the loosening and regaining process, Q Y3 It is the silk drying process.

[0017] Furthermore, when each heat treatment process in step S4 is subjected to a processing strength process test, the calculation method of the processing strength Q of each heat treatment process is characterized by calculating the change process of moisture and temperature, and the calculation formula is: Q=0.5W+0.5Z, where,

[0018] W = F ×∣M1 - M2∣ / (1 - M2)*h;

[0019] Z = F ×∣Z1 - Z2∣ / (1 - Z2)*h;

[0020] In the formula: W is the moisture change rate, % / h; F is the flow rate of tobacco or tobacco sheets, kg / h; M1 is the moisture content of inlet tobacco or tobacco sheets, %; M2 is the moisture content of outlet tobacco or tobacco sheets, %, h is the material passing time; Z is the temperature change rate, ℃ / h; Z1 is the inlet temperature of tobacco or tobacco sheets, ℃; M2 is the outlet temperature of tobacco or tobacco sheets, ℃.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This technical solution is based on the concept of large-scale process. According to the correlation between the previous and next processes, the process of tobacco materials in different heat conversion stages is regarded as a whole. When setting the parameters and intensity of the hot and wet processing process, it should be considered as a whole and set an overall processing intensity. Then the intensity is decomposed into these six key processes. Through a variety of decomposition ideas such as high at the beginning and low at the end, low at the beginning and high at the end, or evenly distributed, process tests are carried out to finally determine the appropriate processing intensity for each process and improve the sensory quality of the final finished cigarette.

Based on the concept of large-scale technology and the correlation between the previous and next processes, the tobacco material in different heat conversion stages is regarded as a whole. When setting the parameters and strength of the hot and wet processing technology, it should be considered as a whole and set an overall processing strength.
