What is the working principle of the ultrasonic cleaner? The following is a brief introduction to the main steps and steps of the work, how the ultrasonic cleaning machine works and the knowledge. The principle of the ultrasonic cleaning machine is mainly to convert the sound energy of the power ultrasonic frequency source into a transducer, and to convert it into mechanical vibration, and to clean the groove to make the cleaning liquid in the groove radiate to the ultrasonic wave. Due to the ultrasonic waves being radiated, the microbubbles in the liquid in the tank can be kept vibrating under the action of sound waves.
When the sound pressure or sound intensity is subjected to a certain degree of pressure, the bubble expands rapidly and then suddenly closes. During this process, the shock wave is generated at the moment when the bubble is closed, so that the pressure around the bubble is 1012-1013pa and the local temperature is adjusted. The huge pressure generated by the ultrasonic cavitation can destroy the insoluble dirt and cause them to differentiate into the solution. The direct repeated impact of steam-type cavitation on dirt.
On the one hand, it destroys the adsorption of dirt and the surface of the cleaning member, on the other hand, it can cause the fatigue damage of the dirt layer to be rejected, the vibration of the gas-type bubble scrubs the solid surface, and once the seam is drilled, the bubble immediately “ Drilling into the vibration causes the soil layer to fall off. Due to cavitation, the two liquids are rapidly dispersed and emulsified at the interface. When the solid particles are wrapped by the oil and adhere to the surface of the cleaning member, the oil is emulsified and the solid particles fall off by themselves. When propagating in the cleaning solution, it will produce positive and negative alternating sound pressure, forming a jet, impacting the cleaning member, and at the same time, due to nonlinear effects, sound and micro-acoustic flow will be generated, and ultrasonic cavitation will produce high speed at the solid and liquid interface. Micro-jet, all these effects, can destroy dirt, remove or weaken the boundary layer, increase the stirring and diffusion, accelerate the dissolution of soluble dirt, and strengthen the cleaning effect of chemical cleaning agent. It can be seen that all liquids can be immersed in the place where the sound field exists, and the characteristics are suitable for the cleaning of parts with very complicated surface shapes. In particular, the use of this technology can reduce the amount of chemical solvents, thereby greatly reducing environmental pollution.

With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.
