Dual-fluid nozzle atomizing experiment device adapted to various atomizing media

Abstract

A dual-fluid nozzle atomizing experiment device adapted to various atomizing media comprises a compressed air system, a water vapor system, a mixing system, a material liquid system and a circuit and control system for adjusting all control mechanisms. Ejection medium flow output by a compressed air and water vapor mixing system and material liquid output by the material liquid system are connected into an air channel inlet and a liquid channel inlet of a dual-fluid nozzle through pipes respectively. According to the atomizing experiment device, compressed air and water vapor mixed in any proportion can be selected as ejection media to be adapted to different types of dual-fluid nozzles. Multiple parameters of temperature, pressure and flow of the ejection media and the material liquid are adjusted respectively, the adjustment range is wide, and the spray quality and the material liquid applying proportion can be effectively controlled; the device is adapted to various atomizing media and experiment parameters, an experiment platform is provided for detecting and evaluating the atomizing effect for enterprises, and the purposes that technological parameters of the ejection media and the material liquid are controlled effectively, the spraying performance and stability are improved, and the flavoring and charging technological quality of tobacco is improved are achieved.

Description

technical field [0001] The invention relates to the field of flavoring and adding tobacco materials, in particular to a two-fluid nozzle atomization experimental device suitable for various atomization media. Background technique [0002] The existing typical tobacco feeding and flavoring process arranges nozzles at both ends of the drum, atomizes the material liquid sent in by the metering pump, and coats the tobacco surface in the form of fine mist groups. The performance of the spray device directly affects the uniformity and effectiveness of flavoring and aroma application, and has an important impact on the sensory quality of tobacco products. [0003] The factors that affect the effectiveness of the uniformity of feeding and flavoring are on the one hand the movement state of the material in the cylinder, and on the other hand, the atomization effect is more important. Insufficient atomization and mist droplets have different sizes, which will easily lead to poor unif...

AI Technical Summary

Problems solved by technology

However, at present, there are many types of atomization media used by cigarette companies (compressed air at room temperature, hot compressed air, and steam). Since there is no experimental platform suitable for various atomization media, after changing or adjusting the formula of the material liquid or changing the nozzle, Optimizing the atomization effect can only be done on the equipment. Due to the limitation of the equipment structure, it is difficult to clearly observe the quality of the atomization effect, and it is difficult to maintain the original optimal atomization state to maintain the consistency of production and processing quality
