The invention feeds back the leaf shred moisture and flow of the material to be blended to the blending material control system, combines the moisture of the blending material and the blending material proportion in the formula design, converts the actual control flow of the blending material to achieve that the dry-based blending proportion of the blending material accords with the product formula design, feeds back the leaf shred or the blending material moisture to a PCL controller of the blending material control system through a signal output end of a moisture meter 4, converts the actual control flow of the blending material according to the leaf shred or blending material moisture condition and the blending material proportion in the formula design, outputs a signal to an output end of a metering scale, and controls the flow of the material through a controller carried by the metering scale to finally obtain the blending material.
The concrete practical application is as follows: taking a leaf shred blending ratio of 15% (dry basis design external blending ratio) in a certain product specification and number formula design as an example, assuming that the weight control blending precision in the actual production process is 100%, adding leaf shreds in a first blending row by using a second conveyer belt 2, the time difference between the leaf shreds passing through a first moisture meter 4 and the falling end of the second conveyer belt 2 and the falling end of the first blending row passing through a second moisture meter 4 and the second conveyer belt 2 is 100s, the leaf shred flow is 4000kg/h, the instantaneous display value of the first moisture meter 4 is 13.2%, the instantaneous display value of the second moisture meter 4 of the first blending after 100s is 12.1%, the PLC controller of the material blending control system needs to delay the instant feedback of the first cut tobacco moisture meter 4 for 100s, the material blending is carried out by controlling the flow rate of the first blending material by the instantaneous flow rate of 4000 x (1-0.132) x 0.15/(1-0.121) =592.49 (kg/h).
