Problems solved by technology

[0006] The moisture meter calibration system disclosed in the above documents has hysteresis, does not have the functions of material moisture prediction and early warning, and cannot check the accuracy of the moisture meter online and in real time, and detect abnormalities of the moisture meter in time
Since the online tobacco moisture meter is an infrared detection device, its key components, light source and filter, are fragile parts. If the abnormal condition of the moisture meter cannot be found in time, the equipment instability will lead to tobacco quality accidents

Abstract

The invention discloses an online moisture meter calibration system and method for a cut tobacco preparation link. The system comprises: an information management system and a moisture meter setting module in communication connection with the information management system, wherein moisture meters are arranged at the front ends of all procedures of a cut tobacco preparation production line, and themoisture meters are defined in a segmented manner; a modeling module which is used for establishing a moisture meter calibration model in sections according to a definition result; a moisture prediction module which is used for carrying out real-time segmented prediction on the material moisture by combining historical batch parameters according to the moisture meter calibration model; and an early warning module which is used for carrying out comparative analysis on the predicted value and the measured value, and carrying out early warning and display on the moisture meters of which the predicted value exceeds the material moisture deviation requirement. The invention aims to provide an online and real-time verification means for the moisture meters on the cut tobacco preparation production line so as to prevent cut tobacco quality accidents caused by unstable equipment.

Description

technical field [0001] The invention relates to the tobacco industry, in particular to the field of online moisture meter calibration in the cigarette shred making process, and in particular to an online moisture meter calibration system and method in the tobacco shred making process. Background technique [0002] In the tobacco production process, the silk production process is a very important link. It is a process in which tobacco leaves are made into qualified shredded tobacco through various processing procedures step by step according to certain procedures according to the physical and chemical properties of tobacco leaf raw materials. In the cigarette production process, the silk-making process is the longest, with the most complicated procedures and the most types of equipment. The existing silk workshop is an assembly-line production operation, which includes key equipment such as vacuum moisture conditioning machine, loose moisture conditioning machine, temporary s...
