Abstract
With the continuous development of modern industry, modern manufacturing technology become more and more developed, and manufacturing methods have become more diversified. As a new molding technology, 3D printer technology has been widespread concerned. 3D printing technology is a rapid molding technology, which is integrated of mechanical, electrical, computer and information. And this technology is rapidly developing, it has been applied to the automotive, aerospace, medical, food industry, construction industry and civil engineering and other industries. In this paper, we focus on the 3D printing of chocolate in the food industry, and study the 3D forming method and the 3D molding technology of chocolate. We mainly design a continuous feeding device for chocolate 3D printing and make it out, we also have carried out relevant experiments and analyzed the work. The main research work is as follows: [资料来源:https://www.doc163.com]
(1) According to 3D printing technology, I have understood the relevant history of 3D printing, and understood a variety of molding technology which used for 3D printing.
(2) For the diversities of chocolate materials, I select the appropriate type of chocolate which is able to be squeezed out, and select molding method which can be used for chocolate 3D printing. After doing these jobs, I can make it easy to design a continuous feeding device for chocolate 3D printing.
(3)I design the structure of the continuous feeding device which used for chocolate 3D printing. And I design the structure of the feed funnel, feed sleeve, screw, nozzle and fixed support. According all of these structures, I mainly design the parameters of the screw and check the intensity of the screw. Then I analyze the nozzle by temperature field and flow field.
(4)I make the whole structure, and carry out the relevant experiments and analysis.
What I do provides a continuous feeding device for chocolate 3D printers and provides a new idea for new chocolate printers.
Key words: 3D printing, Chocolate continuous feeding, Screw, The materials of chocolate.
