On-line spreading rate and uniformity detecting device and method for reconstituted tobacco

Abstract

The invention discloses an on-line spreading rate and uniformity detecting device and an on-line spreading rate and uniformity detecting method for reconstituted tobacco. The detecting device comprises a near-infrared moister meter detecting module, a mechanical movement scanning and examining device, reconstituted tobacco flake conveying devices, a main control center and a signal receiving-transmitting receive. A near-infrared spectroscopic detection principle is adopted; a data processing and analysis algorithm is combined; the on-line quick detection of the spreading rate and the uniformity of the reconstituted tobacco is realized. By using the on-line spreading rate and uniformity detecting device and the on-line spreading rate and uniformity detecting method for the reconstituted tobacco, which are provided by the invention, the real-time on-line detection is carried out on the spreading rate and the uniformity of the reconstituted tobacco in a production process; information can be fed back when a detection result does not accord with a production requirement on the uniformity, so as to be convenient for timely adjustment and control; the detection speed is quick; the precision is high; the stability is good; the repeated calibration is not needed.

Description

technical field [0001] The invention relates to the technical field of detection of reconstituted tobacco leaves by a papermaking method, in particular to an on-line detection device and detection method for the coating rate and uniformity of reconstituted tobacco leaves using near-infrared spectral analysis technology. Background technique [0002] Reconstituted tobacco leaves are sheet or silk regenerated tobacco products (also called tobacco flakes) made by technically processing and recombining tobacco residues such as tobacco powder, shredded stems, and chips during cigarette processing. For the process quality control of reconstituted tobacco leaf products, the current production line has online control equipment for moisture, temperature, slurry concentration and density indicators, and other quality control is blank. Most of them are offline detection, and the results are lagging behind. Strong, such as online detection and feedback of product quantification, coating...

Problems solved by technology

However, the problem with this device is that the selected samples need to be dried, cooled, soaked, etc., which is an off-line detection method, and the detection time is as long as 2.5 hours, which cannot meet the production needs of rapid and on-line detection.

However, the problem with this device is that it is necessary to detect the solid content of the coating liquid after coating on the film base, and the operation is complicated.

However, the problem with this method is that the sampling needs to be placed in a constant temperature box to balance for 48 hours, soaked in distilled water and extracted, and other methods such as drying and weighing are required. This method is also an offline method and cannot meet the production needs of online detection.
