    Can ultrasonic cleaning machines be used for cleaning in the food processing industry?

    As an efficient, safe and reliable cleaning tool, ultrasonic cleaning machine plays an important role in the food processing industry, helping the food processing industry to achieve high standards and requirements for hygienic cleaning. The principle of ultrasonic cleaning technology is that the high-frequency vibration emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation through the transducer, and is transmitted to the liquid in the cleaning tank. The ultrasonic waves radiate forward in alternating density in the liquid, causing the liquid to flow. And generate tens of thousands of tiny bubbles. These bubbles exist in the liquid and vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly and suddenly close. The shock wave generated when the bubbles close can be completely eliminated. Dirt, bacteria and residue on surfaces of food processing equipment and utensils. The following is the relevant content of ultrasonic cleaning machines in the food processing industry.

    First of all, the food processing industry has very strict hygiene requirements for equipment and utensils. Food processing equipment and utensils are often affected by food residues, grease, bacteria and contaminants. If they are not thoroughly cleaned and disinfected, food safety and quality will be affected. Threat, the ultrasonic cleaning machine can use its high-frequency vibration and impact force to completely separate dirt and residues from the surface of food processing equipment to ensure the cleanliness and hygienic condition of the equipment. Not only that, it can also penetrate into tiny gaps and difficult-to-reach areas. Once in the area, remove hidden contaminants and ensure equipment is thoroughly clean.

    Secondly, ultrasonic cleaning machines are also of great significance in cleaning containers and packaging materials in the food processing industry. Food containers and packaging materials need to be thoroughly cleaned and disinfected to ensure food hygiene and safety. Ultrasonic cleaning machines can effectively remove the surface of containers. It can remove dirt, grease and residues, and also remove microorganisms inside the container to ensure the hygiene and cleanliness of the container, which plays an important role in protecting the quality of food and extending the shelf life of food.

    In addition, ultrasonic cleaning machines also play an important role in cleaning tools and accessories during food processing. Tools and accessories such as knives, cutting boards, and conveyor belts used in food processing are often contaminated by food residues, grease, and bacteria. , these contaminants will not only affect food quality, but may also cause cross-contamination and food safety issues. The ultrasonic cleaning machine can quickly remove dirt and bacteria from the surfaces of these tools and accessories through its powerful cleaning ability, ensuring their cleanliness and hygienic condition, and ensuring the safety and hygiene of the food processing process.

    Finally, ultrasonic cleaning machines also have the advantage of energy saving and environmental protection in the food processing industry. Traditional cleaning methods often require a large amount of cleaning agents and water resources, while ultrasonic cleaning machines reduce the use of cleaning agents and water during the cleaning process, reducing the cost of cleaning. The impact on the environment and cleaning costs are reduced. The ultrasonic cleaning machine can also choose vacuum cleaning to prevent the spillage of pollutants and ensure the safety and environmental protection of the cleaning process.

    In summary, ultrasonic cleaning machines can ensure the hygiene and cleanliness of equipment, containers, tools and accessories in the food processing industry, improve the safety and quality of food processing, and provide more efficient, reliable and environmentally friendly cleaning solutions for the food processing industry .

    What are the common cleaning processes for ultrasonic cleaning?

    Everyone should know that ultrasonic cleaning machines are now the preferred cleaning equipment in various industries. However, for all kinds of products in industry, simple ultrasonic cleaning can no longer satisfy people's pursuit of "efficient and clean" cleaning. As a result, various The icing on the cake is the ultrasonic cleaning supporting technology that emerged at the historic moment. Different processes combined with ultrasonic cleaning achieve better results in cleaning different product shapes and dirt. Not only can cleaning be completed faster and more efficiently, but also the workpiece can be cleaned more thoroughly. So what are our common cleaning processes? Woolen cloth?

    01. Ultrasonic cleaning

    Ultrasonic cleaning uses the cavitation effect of ultrasonic waves in liquids to have a direct or indirect effect on liquids and dirt, so that the dirt layer is dispersed, emulsified, and peeled off to achieve the purpose of cleaning.

    Our common hardware parts and auto parts can be easily cleaned by ultrasonic cleaning to remove light oil stains and rust. This is also the cleaning process we use most.

    02. High pressure spray

    High-pressure spray cleaning is a cleaning method that uses high-pressure water flow to impact the surface of an object. Specifically, a high-pressure water pump is used to spray liquid from a fan-shaped spray nozzle at high speed, and the stains that have been softened but not completely peeled off the surface of the workpiece are completely peeled off, comprehensively. Thoroughly clean stains from workpieces.

    For some workpieces with deep holes and many fine holes, after ultrasonic cleaning, there may be some residual dirt that has not come out of the pores. At this time, using a high-pressure spray to perform a rinse can quickly remove the remaining dirt. Some dirt is completely removed, greatly improving cleaning efficiency.

    03. Soak cleaning

    Some workpieces with stubborn stains or complex geometric shapes such as blind holes and grooves are generally cleaned by soaking, that is, the entire workpiece is immersed in the cleaning fluid, and the chemical action of the cleaning fluid is used to soften, separate, and Dissolve difficult-to-treat contaminants on workpiece surfaces.

    Therefore, when we generally clean workpieces that are heavily stained with oil, dirt or glue, soaking them for a period of time and then cleaning them is an indispensable step. After soaking, ultrasonic cleaning can achieve twice the result with half the effort.

    04. Electrolytic cleaning

    By applying electric current, the metal sample acts as an electrode, and an electrochemical reaction occurs between the electrode and the electrolyte. In this process, a redox reaction occurs on the electrode surface, decomposing oxides and dirty substances into soluble substances. Electrolytic cleaning is generally used to remove dirt, oil, rust, sulfide, plastic carbon deposits, gas and other residues on the surface of injection molds, mold cores and accessories.

    05. Vacuum cleaning

    Cleaning in a vacuum state can eliminate the cleaning fluid and the air in the pores of the workpiece, which not only reduces the weakening of ultrasonic waves, but also enables the cleaning fluid to fully contact all surfaces of the workpiece, achieving an all-round cleaning effect without dead ends. Therefore, this cleaning method is generally used for cleaning workpieces that require relatively high cleaning environment, such as some precision hardware or workpieces with more pores.

    06. Steam bath

    Steam bath washing uses saturated steam under high temperature and high pressure to dissolve the oil particles on the surface being cleaned and vaporize them, making the surface cleaned by saturated steam reach a super clean state. At the same time, supersaturated steam can effectively Cut into any tiny holes and cracks to peel and remove stains and residue.

    The above is an introduction to our common ultrasonic cleaning processes. I think everyone should have a little understanding of them. If you don’t know which process is most suitable for the product you want to clean, you can consult us directly.
