即熟型3D食品打印机的设计

针对现有3D食品打印机打印后无法直接烤熟食用的不足,设计了一种恒温加热、恒压匀速出料、快速烤熟的即熟型3D食品打印机.采用虚拟制造技术,通过SolidWorks软件设计3D食品打印机的机械系统,并基于PC机设计了3D食品打印机的测控系统.采用气压传感器实时检测物料瓶内气压,并实现匀速出料控制;采用PT100温度传感器检测烤盘表面温度,实现恒温加热控制;通过有限元分析及实验研究,给出烤盘合适的加热温度和打印轨迹.实验表明,所设计的即熟型3D食品打印机可以高效、高品质地实现食品的3D打印和烤熟,具有较好的实用价值.

Design of Timely Cooked 3D Food Printer

In order to overcome the shortcoming of the existing 3D food printer that cannot be directly cooked after printing,a timely cooked 3D food printer is designed,which can heat with constant temperature,discharge at the uniform speed and constant pressure,and baking quickly.Through virtual manufacturing technology,the mechanical system was designed based on SolidWorks software,and the measurement and control system was designed based on PC platform.The pressure in the material bottle was monitored in real time by using air pressure sensor,and the uniform discharging control was realized.PT100 temperature sensor was used to monitor the surface temperature of the baking pan to realize constant temperature heating control.Through the finite element analysis and experimental study,the appropriate print track and heating temperature of the baking pan were given.Experiments show that the designed timely-cooked 3D food printer can achieve 3D printing and baking of foods with high efficiency and high quality,and has good practical value.
