or clear water + wash shrimp powder
Soak for 5 minutes
Step 2: Shell Brushing
Toothbrush or high pressure water gun rubbing back and forth
Step 3: Lower oil pan
OneMake sure you have enough time to get crayfish thoroughly cooked to sterilize
The above process can be summarized as a holographic spa spa plus 360° horse killing chicken massage. It is called the crayfish world luxury VIP package. The cleaning workload of single digit crayfish is acceptable, but this is a pound. Weighing, pressing, and eating a lot of species…
After 9021, although it is impossible to use artificial intelligence everywhere, it should not be artificially powered from time to time!
Hearing, I started a new ultrasonic cleaning machine next door, and the startup evaluation is very good.

What is the working mechanism?
The tiny bubble core in the liquid vibrates under the action of ultrasonic waves. When the sound pressure reaches a certain value, the bubble will expand rapidly, then suddenly close, and the shock wave will be generated when the bubble is closed. This expansion, closure, oscillation, etc. The kinetic process is the ultrasonic cavitation effect. The cavitation transient can locally generate more than 5000K hotspots (close to the sun surface temperature ), while the pressure is up to thousands of atmospheres (equivalent to 1 ton of weight on a person’s thumb), on the one hand, destroying the adsorption of dirt and the surface of the cleaning member, on the other hand, the dirt layer is removed Clean the surface of the part and disperse it into the cleaning solution [4].
So powerful, why did the crayfish in the video not wash clean enough?
Ultrasonic cleaning is omnipotent, but it is impossible to pay attention to the specific operation. It will be affected by many factors as follows: [5]:
Ultrasonic intensity: the ultrasonic power per unit area. The greater the ultrasonic intensity, the more obvious the cavitation effect, and the better the cleaning effect;
Ultrasonic frequency: low frequency is suitable for initial washing of workpieces, high frequency is strong for ultrasonic direction, suitable for fine object cleaning;
Cleaning solution: The choice of cleaning agent should be considered from two aspects. On the one hand, it should choose the cleaning agent with good chemical effect from the nature of the dirt; on the other hand, choose the cleaning with suitable surface tension, vapor pressure and viscosity. Agent, these characteristics are related to the strength of cavitation;
Cleaning temperature: When the temperature rises, it is conducive to the generation of cavitation, but if the temperature is too high, the vapor pressure in the bubble will increase to reduce the cavitation intensity; each liquid has a cavitation active temperature, and the water is suitable. The temperature is around 60 °C, at which time the cavitation is most active.Target=”_blank” rel=”nofollow” style=”text-decoration: none;”>Chinese Academy of Sciences Institute of Acoustics (ID: cas-ioa)< span class = "text-remarks">, author: He Qi
