Moisture content control method and system of inlet cut tobaccos of cut-tobacco drier

Abstract

The invention discloses a moisture content control method and a moisture content control system of inlet cut tobaccos of a cut-tobacco drier and relates to the technical field of cigarette cutting. The method comprises the following steps: according to set inlet moisture content of the cut-tobacco drier and a first environment parameter set, obtaining a first predication value of loosening and re-moisturizing outlet moisture content; according to a water adding ratio value, and temperature and humidity of a loosening and re-moisturizing phase, obtaining a second predication value of the loosening and re-moisturizing outlet moisture content; judging whether the difference between the first predication value and the second predication value is in a first pre-set range or not; if not, changing the water adding ratio value; and if so, carrying out loosening and re-moisturizing treatment according to the current water adding ratio value. According to the moisture content control method and system, by accurately adjusting the water adding ratio in the loosening and re-moisturizing phase, the moisture content of the inlet cut tobaccos of the cut-tobacco drier is stabilized nearby a process set value, and the effect of stabilizing the moisture content after cut tobacco drying is realized.

Description

technical field [0001] The invention relates to the field of cigarette shred making technology, in particular to a method and system for controlling the moisture content of shredded shreds at the inlet of a shred dryer. Background technique [0002] In the silk production process, the moisture content of the silk at the entrance of the drying silk is an important factor affecting the drying effect. When the moisture content of the incoming material fluctuates greatly before drying, it is easy to cause the stability of the moisture content of the leaf silk to decrease after drying. Therefore, a stable moisture content of the incoming material is conducive to the adjustment of the parameters of the drying process, which can ensure the stability of the moisture content after drying, thereby improving the quality of the cut tobacco. [0003] At present, the main process from the loosening stage of domestic silk thread to the stage of drying silk is as follows: figure 1 As show...

Problems solved by technology

However, in the prior art, the setting of the water addition ratio of the loose moisture regainer is mainly determined by relevant technicians based on personal experience, and the calculation method relied on is a proportional model, that is, the change in the moisture content of the shreds at the inlet of the drying machine is the change in the water addition ratio of the loose moisture regainer A fixed multiple of , regardless of other factors

This method is too simple, and it is easy to cause large deviations in the moisture content of the inlet shreds of the actual shred dryer due to changes in environmental temperature and humidity, which will eventually affect the stability of the moisture content of the shredded shreds at the outlet of the shredded shreds.
