Controllable powder spray food 3D (three-dimensional) printing equipment and method

Abstract

The invention discloses controllable powder spray food 3D (three-dimensional) printing equipment and printing method. A powder feeding device is used for pushing powdery food to an outlet through a horizontally-placed screw rod, and the powder feeding speed at the outlet is controlled by using a vertically placed spiral screw rod. Various powdery foods can be effectively bonded together, and a liquid feeding nozzle can rotate around a powdery food nozzle, so that the liquid feeding nozzle can be always kept behind a powder spout when the powdery food spout moves towards any direction, thereby ensuring the maximum bonding rate of powdery foods. By adopting the printing method, the food printing efficiency and bonding firmness can be increased greatly, the bonding problem of powdery foods in the 3D printing industry is solved effectively, and the application field of 3D printed foods is expanded.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a food processing method and equipment, in particular to a controllable powder spraying food 3D printing equipment and printing method. Background technique [0002] 3D printing technology is a technology that constructs objects by printing layer by layer based on digital model files. It can directly produce parts of any shape from computer graphics data without machining or any mold, thus greatly shortening the product development cycle, improving productivity and reducing production costs. [0003] 3D printing can produce more and more items, from mechanical parts to food, to human organs and so on. With the development of science and technology and social progress, people have higher and higher requirements for food. Consumers not only require food hygiene, but also pay more and more attention to the beautiful appearance of food. However, the development of food graphi...

AI Technical Summary

Problems solved by technology

Consumers not only require food hygiene, but also pay more and more attention to the beautiful appearance of food. However, the development of food graphic appearance processing technology has been relatively slow, and most of the existing food printers are used to print cream, jam, chocolate and other ingredients. The printing of dry powdered food has been slow to develop, and there is little research on the interlayer bonding of different food materials
