Introduction to the working principle of various dishwashers
working principle
Automatic dishwasher
The beautiful dishwasher uses 360° mechanical scouring on the surface of the tableware through high-temperature and high-pressure water flow, as well as the decomposition of oil stains and residues on the surface of the tableware by the detergent, and the soaking and simmering of the food residue by the hot water, so that the oil and residue quickly decompose and fall off, and Achieve the dual effect of cleaning and sterilization. The working method of the beautiful dishwasher is based on the combination of mechanical action and chemical action. The washing mechanism is expressed as follows: 1. Mechanical action 1) Under the driving of the washing pump, the washing liquid is sprayed directly to the surface of the tableware. The direct flushing action of the washing liquid on the surface of the dish is related to the pressure, angle and speed of the jet water ejected from the spray arm. 2) The washing liquid is in the indirect flushing of the surface of the tableware in the spray state. The washing liquid is sprayed back to the tableware and the inner tank, and the washing liquid is sprayed to wash the surface of the tableware. 2. Chemical action 3) By using a water softener containing an ion exchange resin, calcium and magnesium ions which affect the saponification reaction are effectively removed, water quality is improved, and the detergent is fully utilized. 4) The detergent added to the washing process and the grease in the tableware reflect a good alkaline saponification, so that the oil is removed from the tableware. When the water temperature reaches 45 ° C ~ 50 ° C, the active substance can play the most. In view of the unique washing method and washing environment of the dishwasher, the dishwasher has good sterilization and sterilization functions, such as Escherichia coli, Staphylococcus, etc., which can be killed by keeping it at 60 ° C for 20 minutes. Hepatitis B and other viruses that are not easily killed at high temperatures are completely removed by repeated washing and drainage. At the same time, the detergent itself has a good inhibitory effect on various bacteria.
Ultrasonic dishwasher
The ultrasonic dishwasher uses the principle of ultrasonic cleaning: when the ultrasonic wave passes through the liquid medium, it will vibrate the liquid medium at a very high frequency, causing the liquid molecules to generate positive and negative alternating shock waves. When the sound intensity reaches a certain value, tiny cavitation bubbles are rapidly grown in the liquid and are suddenly and strongly closed, and a strong micro-explosion and shock wave are generated to damage the surface of the object to be cleaned and fall off from the surface to be cleaned. Although the effect of each cavitation bubble is not large, there are hundreds of millions of cavitation bubbles per second, which has a good cleaning effect. Since the ultrasonic wave can penetrate the solid substance to vibrate the entire liquid medium and generate cavitation bubbles, the cleaning method does not have a dead angle which cannot be cleaned, and the industry has proved that the ultrasonic cleaning has high cleanliness.
The original dishwasher used a vortex washing principle similar to the current pulsator washing machine, which was troublesome in water, electricity, and washing. Through continuous technological innovation, the dishwasher has achieved a leap from structure, principle to control. The dishwasher technology has reached a perfect level, basically adopting the best washing method: the washing liquid The process is sprayed in a three-dimensional direction onto the surface of the dish to be washed, washed and rinsed, and the entire process of washing, disinfecting and drying is automatically completed.
Jet dishwasher
In the dishwashing process of the dishwasher, the surface of the tableware is washed by the high-temperature and high-pressure jet water flow, the saponification and decomposition of the oil on the surface of the tableware by the detergent, the immersion of the hot water on the residue of the food, and the oil on the surface of the tableware. The residue and food residue quickly decompose and fall off, and the surface of the tableware reproduces clean and bright. Under the dual action of high temperature and high pressure water column scouring and detergent decontamination, the harmful bacteria are effectively eluted to achieve the dual effects of cleaning and sterilization. Mechanical action
1) Under the driving of the washing pump, the washing liquid is sprayed to directly wash the surface of the tableware. The direct flushing action of the washing liquid on the surface of the dish is related to the pressure, angle and speed of the jet water ejected from the spray arm.
2) The washing liquid is in the indirect flushing of the surface of the tableware in the spray state. The washing liquid is sprayed back to the tableware and the inner tank, and the washing liquid is sprayed to wash the surface of the tableware.
Chemical action
1) By using a water softener containing an ion exchange resin, calcium and magnesium ions that affect the saponification reaction are effectively removed, water quality is improved, and the detergent is fully utilized.
2) The detergent added in the washing process and the grease in the tableware have a good alkaline saponification reaction, so that the oil stains are separated from the tableware. When the water temperature reaches 45 ° C ~ 50 ° C, the active substance can play the most.

Hepatitis B and other viruses that are not easily killed at high temperatures are completely removed by repeated washing and drainage. At the same time, the detergent itself has a good inhibitory effect on various bacteria.
Industrial PVC Fast Action Rolling Doors
PVC fast doors can open in a high speed of 2.5m/s. Made from soft PVC curtain, Fast acting rolling doors are used in factory and warehouse, to protect inside clean and improve speed of passing. Fast doors is adopted in most new industrial facility.
