Problems solved by technology

The research on the consistency of processing strength of tobacco in the drying process, along with the research and development of detection technology related to the temperature and atmospheric humidity of the tobacco in the drying drum, is titled "About a method for regulating the consistency of multi-point processing intensity of tobacco drum drying in-process products". Method" patent (authorized announcement number CN106690391B) uses the definite integral of the shredded temperature to the drying path ratio and the definite integral empirical equation analysis of the shredded temperature to the drying time to determine the consistency of the processing intensity, but does not involve the material in the drying kinetics Moisture content is an important parameter, and there is no systematic analysis of the heating process of drum-dried shredded leaves

Embodiment 1

[0030] In Example 1, a certain brand of shredded tobacco with modular formula was used for production. Under the condition of constant drum equipment and processing conditions, 27 batches of drum-dried inner shredded tobacco surface temperature data were continuously measured. To evaluate the consistency of the processing strength index of different batches of drum-dried leaf shreds. The drum processing conditions are as follows: Process flow rate G: 5140.00kg absolute dry material / h, cylinder wall temperature in zone one: 155.00℃, cylinder wall temperature in zone two: 145.00℃, hot air temperature 120.00℃.

[0031] (Remarks: The shredded leaf drying equipment in the cigarette manufacturing industry is mainly tube-plate drum drying equipment. With the continuous upgrading of drying equipment and more perfect functions, the processing mode of drum wall temperature zone control of drum drying equipment has appeared in the cigarette manufacturing industry. That is to say, the ori...

Embodiment 2

[0051] This embodiment 2 selects a representative multi-point processing module formula of a certain brand, and measures the surface temperature data of the leaf silk in the drying drums of A factory, B factory, and C factory under different drum drying equipment and different processing conditions, and evaluates the multi-point processing of a certain brand. Consistency of the processing strength index of the point-processed roller-dried leaf shreds, in which each roller was tested three times.

Abstract

The invention discloses a method for evaluating the consistency of processing strength of shredded leaves in a drum drying process based on the heating process of shredded shreds. B. Obtain the inlet temperature of the shredded blades and the outlet temperature of the shredded blades according to the temperature distribution curve; measure the moisture content of the shredded blades at the outlet of the corresponding drum; C, calculate the processing intensity of the shredded blades in the drying process of the batch according to the above parameters and formula; D. Judging the consistency of shredded shreds processing strength based on the absolute value of the difference between the processing strength of shredded blades in the drying process of the target drum or batch and the processing strength of shredded blades in the drying process of the drum or batch to be tested. The invention realizes the transformation of the processing intensity index of drum-dried shredded leaves from qualitative analysis to quantitative analysis, effectively evaluates the processing effect of different process parameter groups of the same drum, the drum processing effect of different production lines, etc., and has strong guiding significance for the actual production process .

Description

technical field [0001] The invention belongs to the technical field of drying, and in particular relates to a method for evaluating the consistency of processing strength of shredded blades in a drum drying process based on the heating process of shredded blades. Background technique [0002] Cut leaf drying is a key process in cigarette shred production. The purpose is to reduce the moisture content of cut leaf and improve the sensory quality of cut leaf. The setting of drying process parameters directly affects the physical and sensory quality of cut leaf after drying, and affects the aroma characteristics of cigarettes. The sensory quality of leaf silk is more obvious than other silk making processes. The setting of the key parameters of the drying process, the surface is the change of the temperature and moisture content of the material during the drying process, in essence, the physical quality, chemical composition, aroma components of the tobacco leaves, and the senso...
