Ultrasonic dishwashers are very common commercial dishwashers in commercial kitchens. So what about this commercial dishwasher? What are its advantages and disadvantages? Working principle The working principle of ultrasonic dishwashers is that when the sound emitted by the ultrasonic generator passes through the liquid medium, it compresses the liquid medium to vibrate at an extremely high frequency, causing the liquid molecules to produce positive and negative alternating shock waves. When the sound intensity reaches a certain value, tiny cavitation bubbles grow rapidly in the liquid and close instantly and strongly, producing strong micro-explosions and shock waves, which destroy the dirt on the surface of the object being cleaned and fall off the surface being cleaned. This cleaning method does not have dead corners that cannot be cleaned, and has high cleanliness. It is often used as a dishwashing device or pretreatment equipment in commercial kitchens. It has strong cleaning ability and does not require special detergents. It only needs to be used with traditional detergents. The price is also relatively low, but due to the high noise, it requires secondary cleaning. It has gradually been replaced by lid-type dishwashers or small long dragon dishwashers. Advantages of ultrasonic dishwashers: Efficient cleaning: Ultrasonic dishwashers use the power of high-frequency vibration and micro-jets to penetrate into the tiny gaps and hard-to-reach corners on the surface of tableware, effectively remove stains such as oil stains and food residues, and achieve efficient cleaning. Save water and electricity: Compared with traditional spray-type dishwashers, ultrasonic dishwashers usually do not require a large amount of running water during the washing process, so they can significantly save water resources. At the same time, due to the high energy conversion efficiency of ultrasonic vibrations, its energy consumption is relatively low. No dead corner cleaning: Ultrasonic waves have strong penetrating power, which can ensure that every corner of the tableware is fully cleaned, avoiding the problem of dead corners that may exist in traditional dishwashers. Gentle washing: The washing method of ultrasonic dishwashers is relatively gentle, and will not scratch or damage the surface of tableware, which is conducive to protecting the integrity of tableware and extending its service life. Applicable to traditional detergents: No special dishwasher detergent is required, only traditional detergents are needed to be used. Low price: Ultrasonic dishwashers are simple in structure and low in production cost, so the price is not high. Long service life: Ultrasonic dishwashers have a simple structure and simple functions, so they have a good service life. Disadvantages of ultrasonic dishwashers: Manual cleaning is required: Ultrasonic dishwashers need to be combined with manual scrubbing, and cannot be fully automatic. Secondary cleaning is required: Since ultrasonic dishwashers need to be combined with detergent, manual secondary cleaning with clean water is required after the first cleaning. Disadvantages of dishwashing liquid: The advantages of using traditional dishwashing liquid naturally inherit the disadvantages of dishwashing liquid. In addition to the need for secondary cleaning, the cleaning ability is not as strong as that of special detergents. Loud working noise: Ultrasonic dishwashers work through high-frequency vibration, so they naturally cannot avoid the disadvantage of loud working noise. Large floor space: Commercial kitchens generally wash a large amount of dishes, and ultrasonic dishwashers require a certain amount of soaking, so a larger volume is required to place tableware, which also leads to a larger floor space for dishwashers. It takes a certain amount of cleaning time: It requires manual scrubbing, which also makes it impossible for ultrasonic dishwashers to be quickly cleaned and used quickly. This is not suitable for restaurants with high turnover rates and high frequency of repeated use. The above is the working principle and advantages and disadvantages of ultrasonic dishwashers. Commercial dishwashers have many different types to meet the needs of different customers. Different types of commercial dishwashers can be selected according to their actual business needs.
