Hot air heating type food 3D printing spray head and application

Abstract

The invention discloses a hot air heating type food 3D printing spray head. The hot air heating type food 3D printing spray head comprises a connecting pipe, a spray head body and a pair of hot air supply mechanisms, the connecting pipe is connected to the end of the spray head body, a pair of hot air supply mechanisms facing the spray head position of the spray head body are arranged on the two sides of the spray head body, and a pair of symmetrical angle adjusting connecting assemblies are arranged on the two sides of the spray head body and connected with the pair of hot air supply mechanisms. The hot air heating type food 3D printing spray head has the beneficial effects that the hot air heating type food 3D printing spray head is simple in structure and convenient to use, and the formula of plant meat is improved in order to solve the problems that existing plant meat is poor in protein extrudability, poor in fracture performance and low in printing forming plasticity; and meanwhile, the problem that an existing 3D printing equipment spray head cannot perform accurate texture design is solved, the problem that the bottom layer is prone to drying up is solved, an external air supply heating mode is adopted, materials sprayed out of the spray head are rapidly heated, the materials rapidly fall onto a station, and therefore accurate and rapid 3D printing of real objects is completed.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a hot air heating food 3D printing nozzle and its application. Background technique [0002] 3D printing constructs objects through layer-by-layer printing and digital control, and is used in many fields such as aerospace, medicine, clothing, and art. In recent years, people have tried to apply 3D printing technology to the food field, using 3D printers in chocolate, biscuits and other foods to meet the individual needs of the people. The molding methods currently used in food 3D printing include extrusion molding, powder sintering, binder jetting, and inkjet printing. Among them, extrusion printing is the most commonly used printing molding method, which is suitable for paste and can be printed A variety of ingredients. The 3D printing nozzle is the core item of the extrusion 3D printer, which largely determines the printing quality. The smoothness of the extruded filamen...

Problems solved by technology

[0007] 1. In terms of extrusion slurry, the raw material of plant protein meat on the market generally uses a mixture of soybean protein isolate-gluten powder, which has certain defects when it is applied to food 3D printing plant protein meat, such as poor extrusion, poor fracture, and printing plasticity Inadequate printing accuracy of raw material pulp, etc., cannot realize accurate texture construction technology

[0008] 2. In terms of the performance of the 3D printer nozzle, most of the desktop 3D printers with heating function, the heating part is the entire deposition environment or the barrel. The denaturation of the protein in the cylinder will greatly reduce the extrusion characteristics of the material, so that the precise texture design of the food cannot be achieved, and the smoothness and self-supporting performance of the silk cannot be guaranteed. In view of this, in-depth research on the above problems has led to this case produce
