Three-dimensional Printer coupled with Microwave and Printing Method applied for Food design

摘要

The disclosure discloses a three-dimensional printer coupled with microwave and printing method applied for food design, and belongs to the technical field of food. A microwave heating probe embedded in the inner wall of a barrel releases microwaves at the front end, and in combination with the setting of a vertical distance between the front end of the microwave heating probe and an extrusion nozzle, that is, the setting of the size of a non-absorbing material, the effect of instant curing of an extruded material is realized; through the design of a bell mouth and a choke groove of an anti-leakage unit, and in combination with the design of an absorbing material of a printing platform, the heating efficiency of a product is effectively improved, and microwave leakage and diffusion are prevented; a cooling device is disposed so as to ensure that a material to be printed in the barrel is not cured by microwave heating before the material to be printed enters the extrusion nozzle; a microwave solid-state oscillator generates microwaves, and a transmission line transmits the microwaves, so that the microwave output is stable, the power and frequency can be adjusted according to printing needs, and the microwave solid-state oscillator is small in volume and convenient to integrate; and a mode of printing while heating and curing is adopted, so that a printed product structure has high mechanical strength, the manufacture of a hollow unsupported three-dimensional structure can be realized, and the shape of the product is not easy to collapse.
