Abstract: A multi-frequency ultrasound coupled multi-nozzle food additive manufacturing device and method are provided. A multi-frequency ultrasound coupling printing system is set up on a multi-nozzle additive manufacturing device, which improves the rheological properties of high-viscosity and large-particle food ink by generating a cavitation effect through the high-frequency vibration of ultrasound and improves the printability of food ink while retaining the nutrients and texture of the food ink. The application of the multi-frequency ultrasound coupled multi-nozzle device to food additive manufacturing enables it to achieve a smaller nozzle diameter and higher printing speed than conventional additive manufacturing systems, which improves the printability of the food ink while realizing large-scale production.
