Recently some friends have asked me, ultrasonic cleaning is now so popular, cleaning effect so good. So, can the ultrasonic cleaner clean the dishes? The answer, of course, is yes. Now there are ultrasonic dishwashers appear on the market, which means that the ultrasonic washing machine for tableware cleaning effect is recognized by the community.
Ultrasonic wave is a sound wave with a frequency higher than 20000 Hz. It has good directivity, strong penetrating ability, easy to obtain more concentrated sound energy, and can travel long distance in water, can be used for ranging, speed measurement, cleaning, welding, gravel, sterilization and other disinfection. It has many applications in medicine, military affairs, industry and agriculture. Ultrasound is so named because the lower limit of its frequency is approximately equal to the upper limit of human hearing. The principle of ultrasonic cleaning machine is to convert the sound energy of power ultrasonic frequency source into mechanical vibration through transducer, and to radiate the ultrasonic wave to the cleaning liquid in the tank by cleaning the tank wall. Because of the ultrasonic radiation, the micro-bubbles in the liquid in the tank can keep the vibration under the action of the sound wave.
When the pressure or intensity of sound decreases to a certain degree, the bubble expands rapidly and then suddenly closes again. During this process, a shock wave is generated at the moment the bubble closes, causing a pressure of 1012-1013 pa around the bubble and local temperature regulation, this ultrasonic cavitation generated by the enormous pressure can destroy the insoluble dirt and make them differentiated in the solution, steam cavitation on the dirt of direct repeated impact. Therefore, its cleaning effect is very prominent, and without any toxic side effects.
The advantages of ultrasonic washing machine:
1, power saving, water saving, low noise because the ultrasonic washing machine does not need a motor, cleaning does not need the traditional dishwasher arm rotation mechanism, impeller mechanism, do not need pump, motor, circulating water system, all only rely on the vibration of water molecules to produce cleaning, low noise machine, water and electricity saving.
2. The Dishwasher has a simple structure and long service life because it uses the vibration of water molecules generated by ultrasonic waves to wash dishes, and does not need a spray arm rotating mechanism, a water mixing impeller mechanism, a water pump, a motor, a circulating water system, etc. , so the structure is simpler, the failure rate is much lower, and the maintenance and The Adjuster are simpler. Traditional dishwashers rely mainly on the chemical cleaning action of special detergents, while ultrasonic dishwashers do not require detergents in principle. The addition of detergent only plays an auxiliary role, there is no special requirements for detergents.
4, high cleanliness, no dead angle ultrasonic cleaning machine using high frequency vibration water cleaning, high cleanliness, there is no dead angle can not be cleaned. Especially suitable for the cleaning of Chinese tableware. At the same time, the conventional ultrasonic cleaning machine can wash about 1500-2000 dishes per hour, compared to the traditional manual cleaning is very efficient, very convenient and simple to operate. General use of stainless steel equipment, more safe, cleaner, not easy to rust, not easy to deformation, durable.
