Abstract

The invention discloses a food microwave three-dimensional printing method and a printer, which belong to the technical field of food. Through the microwave heating probe embedded in the inner wall of the barrel, the microwave is released at the front end, combined with the size setting of the non-absorbing material, the effect of instant curing of the extruded material is realized; through the design of the bell mouth and choke groove of the anti-leakage unit, combined with the printing platform The microwave-absorbing material design can effectively improve the heating efficiency of the product and prevent microwave leakage and diffusion; the microwave solid-state source is generated and the transmission line conducts the microwave, so that the microwave output is stable, and the power and frequency can be adjusted according to the printing requirements. The microwave solid-state source is small and easy to integrate ;By heating and curing while printing, the printed product structure has high mechanical strength, which can realize the production of hollow unsupported three-dimensional structure, and the product shape is not easy to collapse.

Description

technical field [0001] The invention relates to a food microwave three-dimensional printing method, a printer and an application thereof, belonging to the technical field of food. Background technique [0002] 3D printing is a new type of manufacturing method. It performs layer-by-layer printing and layer-by-layer printing to manufacture parts according to the instructions of the control system. Compared with traditional manufacturing methods, it has the characteristics of fast speed, wide application range and high precision. At present, 3D printing is mainly used in the food field to print temperature-sensitive materials such as chocolate and self-mixed paste, and most of them use Fused Deposition Modeling (Fused Deposition Modeling, FDM) technology. FDM technology is to extrude the molten or slurry food fluid from the nozzle and accumulate it on the platform. Due to the low melting point of chocolate, the molten chocolate is extruded from the barrel, and it will be fixed...
