The advantages and the application of ultrasonic cutting knife for cutting food
The development of ultrasonic technology has also made it possible to use ultrasonic to cut products. Ultrasonic cutting technology has been continuously developed and improved, and has been used to cut industrial products such as food, rubber, and fabrics. The ultrasonic cutting machine can vibrate its blade 20,000-40,000 times per second (20-40 kHz). Due to this high frequency vibration, the ultrasonic cutting machine can cut food easily. The application of ultrasonic cutting food is currently widely used in the processing of bread, cakes, cheese and other foods.
Cutting principle
Ultrasonic cutting is the use of high-frequency vibration of ultrasonic waves for food cutting, which to a certain extent is called a vibrating blade rather than a static blade in the traditional sense. High-frequency ultrasonic vibration can provide a frictionless cutting surface, which can not only maintain the cleanliness of the blade, but also reduce the number of production shutdowns and improve the efficiency of food processing. At the same time, ultrasonic high-frequency vibration can also locally heat the cutting part of the food, which can largely avoid uneven edges and loose food tissue.
Insufficient traditional cutting
Although the traditional mechanical cutting method is relatively cheap, there are many limitations in cutting food. For example, using traditional knives to cut cakes, due to the softness of the cakes, during the cutting process, problems such as deformation and breakage of the cakes are prone to occur, which damages the appearance of the cakes and causes waste. Although the appearance of cake cutters has greatly improved the efficiency of cake cutting, the problem of uneven cutting edges and easy breakage still exists. Moreover, the automatic cake cutting only uses stainless steel cutting blades, and some butter cakes themselves are relatively sticky, so the blades often stick together, which will also affect the overall work efficiency. For example, foods such as bread and cheese similar to cakes have similar problems.
Advantages of ultrasonic cutting
Efficient cutting
Ultrasonic cutting technology is quite different from general cutting. On the basis of ensuring precise cutting, it will not cause damage to the cut product and retain the integrity of the cut to the greatest extent. The ultrasonic cutting knife is carried out by a four-axis drive system with precise and fast servo drives. The entire system can speed up the cutting progress while making the ultrasonic cutting machine consume less energy. Integrating the use of ultrasonic cutting machines into industrial processes can save time, increase productivity, and increase productivity to the greatest extent.
Low environmental impact
Ultrasonic cutting knife will only produce a small noise during the cutting process, no other equipment is needed for anti-noise treatment, and it will not cause harm to the human body. Ultrasonic cutting machines will not have a negative impact on the ecosystem. It is recognized that its use is not dangerous in an industrial environment. Cutting and ultrasonic welding is a reliable technology that respects the environment.
Clean and hygienic
For food cutting, food hygiene is essential. The process of implementing ultrasonic food cutting must comply with strict sanitary conditions to reduce the risk of food contamination. At the same time, because the ultrasonic cutting knife has the characteristics of low friction, there is little adhesion when cutting food, and the cleaning cost is reduced while keeping the blade clean.
Keep the edges flat
Ultrasonic cutting will locally heat the cutting surface of the food during the cutting process, and the cutting part has a fusion effect. Therefore, the cutting surface of the food can be perfectly sealed, and the internal structure of the food is not loosened while maintaining the beauty.
Accurate cutting at any angle
Compared with traditional knife cutting, the cutting quality that can be obtained by using an ultrasonic cutting machine is much better. Ultrasonic cutting machines have extremely high accuracy and can better meet various cutting restrictions in industrial environments. Ultrasonic cutters are small in size, convenient and flexible, and can be used in conjunction with robotic arms and automated equipment. Through the combination with robotic arms or automated equipment, the purpose of cutting food at any angle can be realized, and the ideal food shape can be obtained to the greatest extent.
Scope of application
Ultrasonic cutters can easily achieve precise cutting of foods such as bread, cakes, cheese, and frozen foods. In addition, the ultrasonic food cutting knife can also cut items containing vegetables, meat, nuts, or food containing ingredients such as fat, sugar, cream, and chocolate, and the internal products will not be deformed or shifted. Ultrasonic cutting technology can easily pass through the interior of multi-level food without causing food deformation, thereby improving cutting quality and consistency.
Although the ultrasonic food cutter can cut foods including cakes, breads, frozen foods, cheese, etc., it has the advantages of high efficiency, energy saving, and self-cleaning, but it is not a panacea. It also has a range of cutting food, once it exceeds the applicable range of ultrasonic food cutting, it may cause damage to the knife. Therefore, before buying and using a food cutter, you must understand its scope and characteristics.
