Abstract
A method for evaluating the processing characteristics of tobacco leaves features that the technical parameters for each steps in preparing tobacco shreds procedure to form several processing intensity gradients, which are used to process the raw tobacco leaves for finding out the optimal processing intensity for particular raw tobacco leaf, so improving the quality of cigarettes.
Description
Technical field
The present invention relates to a kind of evaluation method of tobacco leaf processing characteristics.
Technical background
Along with deepening continuously of cigarette process technical research in the last few years, cigarette processing is progressively changed to paying attention to the aesthetic quality by the physical quality of presentation quality that stresses product and processing, technology is outstanding further to the effect of product quality, and the characteristic of cigarette composition and processing technology will become one of the important content of the autonomous core technology of " Chinese style cigarette " undoubtedly.Yet, at present in China's production of cigarettes, although all having had significantly, the physical quality of processing and the oeverall quality of product improve, but after the proposition of Chinese style cigarette, present cigarette technology exists many and the incompatible aspect of the demand for development Chinese style cigarette, mainly show as: 1. the used cigarette raw material of kinds of cigarettes product, process equipment, processing process and target setting are identical, cause the fragrance style and the taste feature of kinds of cigarettes product not obvious, the product homogeneity phenomenon is comparatively general; 2. present, production of cigarettes is the hybrid process of raw material, and on the one hand, the condition of processing and parameter are set the potential quality that can not give full play to the kinds of cigarettes raw material; On the other hand, cause the production of high-grade cigarette to have to depend on excessively the cigarette raw material, production of cigarettes uses high price prescription, high-grade raw material problem more outstanding, and the cost of production of cigarettes is higher; In addition, when cigarette continues to fall Jiao, also be unfavorable for keeping effectively the fragrance matter and the perfume quantity of cigarette, be unfavorable for continuing to satisfy the demand of consumer cigarette flavor.
Summary of the invention
The objective of the invention is to adopt cigarette tobacco leaf formulation whole by cigarette fiber tow production equipment at above-mentioned cigarette enterprise, selected same technology parameter, can not give full play to problems such as cigarette Material Characteristics and use value, and a kind of evaluation method of tobacco leaf processing characteristics is provided.
The objective of the invention is to realize by following scheme:
The evaluation method of tobacco leaf processing characteristics of the present invention is by adjusting each single operation process technology parameter of cigarette throwing, form several different processing intensity gradients, raw tobacco material is handled research, find out the evaluation method that is fit to the suitable processing of kinds of cigarettes raw tobacco material intensity, this evaluation method may further comprise the steps:
(1) selected production process adjustment processing intensity: reselection procedure to the bigger production process of tobacco leaf aesthetic quality influence, this operation ordinary production technical data condition is defined as the 3rd grade, i.e. " intensity 3 "; According to equipment performance, adjust parameters such as steam (or hot blast) temperature and flow, injection flow rate, throttle opening, moisture regain temperature, determine that two grades low processing intensity are intensity 1, intensity 2, with the technical data that two grades of higher processing intensity are intensity 4, intensity 5, form this production process and handle the raw tobacco material technical data of totally five groups of different processing intensity;
(2) sampling method: equipment is in stable duty before the sampling, and pre-determine the front and back sample point of operation, accurately measure the technology time of staying of material, determine raw tobacco material kind, producing region, grade, number of times, quantity and the sampling interval time of sampling by operation;
(3) method for making sample: 1. the leaf sample moisture content is regulated: the moisture content of leaf sample is adjusted to 18%-19%, to satisfy the chopping requirement; Adding tide for moisture content sample less than normal handles; For moisture content sample bigger than normal adopt nature to dry or otherwise processed to the 18%-19% moisture content of suitable chopping, but must not force oven dry; 2. blade chopping: will regulate machine chopping on the leaf sample of moisture content, requiring tobacco cut width is 0.95mm, and evenly; 3. the tobacco sample moisture content is regulated: adjusting the tobacco sample moisture content is 12.5% ± 0.5%, satisfies rolling requirement, must not force oven dry; 4. sample rolls: the satisfactory tobacco sample of moisture content is fully mixed, adopt that machine rolls on the same cigarette material, and control well and roll uniformity and cigarette Zhi Pinzhi;
(4) sensory quality assessment and result judge
Sensory quality assessment is the content that the raw tobacco material processing characteristics is estimated.Its objective is that exploring different raw tobacco materials handles intensity at the optimised process of each operation, inquires into the influence degree of main production process different process technical parameter condition to the raw tobacco material aesthetic quality simultaneously;
1. sensory quality assessment index: the sensory quality assessment index comprises aroma characteristic, flue gas characteristic and mouthfeel characteristic;
2. the demarcation of raw tobacco material before operation is handled: participate in personnel's process of smokeing panel test and consult, aesthetic quality's level of this raw tobacco material sample played the effect of calibrating the bore of smokeing panel test simultaneously before unified operation was handled;
3. the result judges: by the sensory evaluating smoking, relatively after the raw tobacco material process operation different disposal intensity, with the preceding situation of change the aesthetic quality of processing, judge the optimization process intensity of different raw tobacco materials in this operation;
Following table has been listed the content and the explanation of sensory quality assessment:
| Aroma characteristic | Flue gas characteristic | Mouthfeel characteristic | Fragrance style intensity of variation (0,1,2) | Remarks | ||||||||||||||
