Online control method for tobacco processing process parameters by using computer programs

Abstract

The invention discloses an online control method for tobacco processing process parameters by using computer programs, which comprises the following steps of: acquiring temperature and humidity parameter values of a processed material, namely tobacco leaves or tobacco shreds through a temperature sensor and a moisture meter, acquiring running parameters of the real-time online acquisition processing process and the temperature or the humidity of the tobacco leaves or the tobacco shreds, comparing the running parameters of the real-time online acquisition processing process equipment and the temperature and humidity parameter values of the tobacco leaves or the tobacco shreds with the acquired parameter values of the temperature or the humidity of the tobacco leaves or the tobacco shreds before processing, transmitting modification instructions of control parameter setting provided by a data monitoring system to a programmable logic controller (PLC), and timely adjusting online control parameters and output instruction signals of the equipment to realize online real-time adjustment of the tobacco processing process parameters. Therefore, dynamic control of raw material change in the tobacco online processing process is realized. The method is suitable for controlling tobacco shredding, threshing and re-drying, CO2 expanded tobacco shred lines, rolling and packing.

Description

technical field [0001] The present invention relates to an on-line control method of tobacco processing process parameters by using computer programs in the process of tobacco processing, in particular to a novel tobacco processing control method capable of correcting finished product results in real time according to processing process parameters and adjusting a control system in real time. Background technique [0002] The current traditional cigarette product processing process control is that the equipment control layer takes the moisture and temperature of the tobacco after the processing as the control target, and feeds back the moisture and temperature parameters of the processed output to the PLC control system input through the detection results after processing. Signal, use the PID closed-loop control unit in the PLC programmable controller to adjust the executive devices configured by the processing equipment, such as moisture-discharging doors and steam valves, so...

But this is far from enough for the requirements of the product's inherent quality and stability indicators

These acceptance "standard" parameters are only intermediate monitoring variables for equipment to detect product quality, not the real quality indicators of the product, let alone guarantee the stability of the internal quality of the product

In other words, although the operation of the equipment that meets the single control target, the control of the stability index is the result of the combined action of multiple control parameters; second, although the internal sensory quality of the product that meets this control target is not necessarily qualified, let alone Stable, even if the intermediate control parameters are inappropriate, the processed products may already be waste products, while the test results of traditional methods can still meet these indicators

[0005] 3. Due to the limitations of detection methods, the internal quality parameters of the product, such as color, taste, aftertaste, miscellaneous smell, coordination, aroma quantity, aroma quality, fullness, cannot be sampled, detected and controlled in real time

These indicators cannot be strictly, accurately and stably controlled during the processing process, and it is difficult to achieve the goal of Chinese-style cigarettes
