Research On Vehicle Food 3D Printing Technology

With the improvement of living standard,people's demand for the quality,taste and diversity of daily consumer food is increasing.The food industry is undergoing a major change,and the demands are gradually turning to customization.And 3D printing technology is the key to achieve personalized food customization.Compared with other food processing technologies,food 3D printing technology is exquisitely processed,and the process is more interesting and intelligent.At the same time,food can be customized according to everyone's physical conditions and preferences,and is loved by people.3D printing technology is a material-increasing manufacturing,in raw materials to consider more eco-saving.This article will be food 3D beat A new type of food 3D printer,the on-board food 3D printer,is put forward,which is the key technology of the research and optimization,which creates the possibility for realizing the mobile private custom food,can realize the personalized customization of the mobile food,and fills the gap in this field.The specific research work is as follows: This paper expounds the research background and significance of food 3D printing technology,introduces the advantages and disadvantages of different kinds of 3D printing technology,and analyzes the advantages and disadvantages of FDM printing technology.The development of food 3D printing technology at home and abroad and the development trend of food 3D printing in the future are analyzed.A new type of food 3D printer,vehicle food 3D printer,is proposed,which can realize the personalized customization of movable food and fill in the blank in this field.1.The design improves a set of internal system structure of food 3D printing suitable for vehicle.The mechanical motion device of 3D printer at home and abroad is analyzed and improved,and the three-axis motion device of sprinkler is designed,as well as the Z-axis ball screw drive and XY two-axis synchronous belt drive.A 3D printing method is designed based on the special material of food and the special conditions that need to besatisfied with the vehicle.A sprinkler extrusion device,piston extrusion,is selected to meet the requirements of food 3D printing and on-board device.Referring to the idea of automatic tool changing device of NC machine tool,the device of automatic conversion sprinkler is designed,which can make 3D printing of different materials mixed with different materials and make it more precise.A model of beauty.The internal basic structure of food 3D printer is optimized to make printing more convenient and rapid.2.The forming conditions of chocolate were analyzed.It was determined that the melting point temperature of chocolate was 31 ? and the heating temperature was 35 ?.At the same time,considering the frosting temperature of chocolate,the optimum molding temperature of chocolate was determined at 8 ?-16 ?.The temperature field of sprinkler part and 3D printer molding chamber is simulated by Solidworks,Ansys Fluent software.Based on semiconductor refrigeration technology,the optimum forming conditions of chocolate 3D printing are constructed.finally,the effective heating power of 5W heating ring and 12 W effective refrigeration power of two semiconductor refrigerators are obtained.Utilization.The deformation and stress of printer forming chamber model are calculated by Workbench software,which provides a theoretical basis for the research and development of food 3D printer.3.The characteristics of food materials and the theoretical model of silk production were analyzed,and the chocolate 3D printing experiment was carried out.according to the experiment,the effects of the moving speed of the nozzle,the diameter of the nozzle and the temperature of the nozzle on the printing model were analyzed,and the optimum parameters suitable for 3D printing of chocolate materials were determined: v ? 20 mm / s;The temperature of sprinkler has little effect on 1.5 mm.Combined with the experimental analysis of the hanging flow problem of food materials,according to the image of the proposed synthesis,it is found that when the piston suction distance is about 0.6mm,the chocolate ingredients will not hang up.According to the simulation results,the experimental verification is carried out,and the printed model can verify the model.The correctness of the scheme.The recipe modulation and 3D printing of cookies were carried out,and the accuracy analysis of the printing results was carried out: the side length error rate was 5.64%;the height error rate was 3.33%;and the angle error rate was 5.33%.Finally,3D prints a mixed-food model,Mahjong Red Zhong,which verifies that the printer can do mixed printing of food materials.4.Finally,the conceptual design and summary of solar new energy mobile dining car,which is the carrier of food 3D printer,are carried out.On the basis of ensuring the normal operation of the dining car,the design concept of the dining car is to ensure that the food3 D printer and other cooking utensils in the car can work normally.Based on the analysis of the working principle of the dining car,based on several different working states of the dining car and referring to the favorite food types,the food production functions,including the food 3D printing area and other production areas,are worked out.The expansion state of photovoltaic board is designed as sunshade,and the distributed off-grid power generation system is selected for the power generation system.Finally,the whole vehicle control system of new energy dining car is given.Design and analysis are carried out.It provides ideas for the research of vehicle electrical appliances in the future.
