Description

Technical Field

[0001] The present invention relates to the technical field of tobacco equipment accessories, in particular to a dual-medium nozzle atomization effect verification device and a verification method thereof. Background Art

[0002] In the tobacco shred production process, flavoring is a key process step. The tobacco shreds are evenly loosened by the rotating drum. Flavoring is then atomized by compressed air through a dual-media nozzle and evenly sprayed onto the tobacco surface, completing the flavoring process. However, current flavoring processes face numerous challenges in controlling the atomization efficiency of the dual-media nozzles. The air pressure and nozzle gap directly affect the atomization efficiency, which in turn affects the uniformity of flavoring. If the atomization pressure is too low, the feed liquid is incompletely atomized, hindering the absorption of the feed liquid by the tobacco shreds and resulting in yellow spots and wet clumps. If the atomization pressure is too high, the sprayed feed liquid spray column disperses the feed material and directly impacts the inner wall of the drum, causing a large amount of tobacco to adhere to the wall. Furthermore, excessive atomization pressure results in a small droplet size, and drifting droplets are easily discharged under the negative pressure of the dehumidification fan, resulting in waste of feed liquid. In addition, during the production process, the nozzle's spray distance, atomization radius, atomization effect, and whether the nozzle is leaking cannot be observed. Currently, the only way to test the nozzle's atomization effect is to use water during maintenance and observation outside the drum. This process requires the cooperation of multiple people and poses certain safety hazards. Moreover, due to the closed environment of drum-type equipment, the observation window period is very short, and the atomization effect cannot be clearly viewed. Once the atomization effect is poor during the production process, it directly affects the product process quality, causing serious quality risks and hidden dangers. The existing technology lacks a device that can effectively simulate actual working conditions, accurately test the atomization effect of dual-media nozzles, and adjust the nozzle angle, control pressure and flow. It is difficult to meet the needs of tobacco silk making and flavoring processes for precise control and detection of the atomization effect of dual-media nozzles. Summary of the Invention
