Filling production line for defoaming by using ultrasonic wave

Abstract

The invention relates to a filling production line for defoaming by using ultrasonic wave. The filling production line comprises an ultrasonic generation device and a conveyor belt device, wherein the ultrasonic generation device comprises a tool head which is sequentially connected with an amplitude-change pole, an ultrasonic transducer and an ultrasonic drive power supply; the conveyor belt device comprises a conveyor belt; the conveyor belt is positioned below the ultrasonic generation device; a central axis of the tool head is vertical to the central axis of the conveyor belt; the lower end face of the tool head is parallel to the surface of the conveyor belt; a pot mouth liquid level of a pot body on the conveyor belt is not contacted with the lower end face of the tool head. The invention provides a convenient and efficient defoaming technology specially used for the filling production line. In the entire defoaming process, a defoamer is not used, a manner of in-container vacuumizing limited by container is not adopted, and the automation technology of defoaming the pot mouth liquid level by the filling production line is realized through pushing effect of the automated conveyor belt and the wave focusing effect of the tool head.

Description

technical field [0001] The invention relates to the fields of food, beverage and chemical industry, and mainly solves the foam generated by filling or stirring reaction and liquid level instability, and in particular relates to a filling production line using ultrasonic defoaming. Background technique [0002] Foam is composed of raw material liquid and gas. The loss of foam will cause the loss of raw material liquid and the loss of production output; and the existence of bubbles will affect the properties of the solution. [0003] At present, the main defoaming techniques are chemical defoaming method and physical defoaming method. [0004] Chemical defoaming method: mainly adding a defoamer to eliminate bubbles after foaming. The main mechanism is: the defoamer reacts with the foaming agent or directly changes the physical properties of the liquid film, thereby changing the state of the liquid film and reducing Foam stability, to achieve the purpose of breaking the foam. ...

AI Technical Summary

Problems solved by technology

However, the current physical defoaming device has low efficiency and a small amount of foam treatment, and further research and improvement are needed

[0006] For the filling production line, the foam generated due to the stirring reaction and the unstable liquid level will not only cause serious mist entrainment, but also cause serious waste of resources in the production process; more importantly, the foam caused by the difficulty of controlling the foam Escaping can endanger the environment
