| The mechanization of rice wine production in Guizhou Province is still at a low level,and it is still the traditional production mode.Some rice wine brewing enterprises have introduced brewing devices,but the automation and intelligence of these brewing devices are not high,and the whole system has not been built into an automated production line;Home workshop brewing devices are mainly simple devices with single cooking and distillation functions,and there are few automatic production devices.Therefore,the use of modern fermentation engineering technology to improve the traditional food production process has become an inevitable trend of the development of the times.By analyzing the key control indicators and control nodes that affect the brewing process and product quality,a standardized rice wine and koji production process has been established,and an intelligent rice wine production line has been established by using digital design and manufacturing technology,combined with perceptual IOT and intelligent control technology,To realize the fine operation and quantitative control of rice wine production and ensure the stability of rice wine quality.It is of great significance to carry out the research topic of automatic rice wine brewing device,break the brewing method of family workshops,and improve the brewing industrial technology of small and medium-sized rice wine brewing enterprises;in addition,the automatic rice wine brewing device can also be used as field equipment to provide data for the terminal to promote the development of Guizhou rice wine industry.The research content and process of this paper are as follows:(1)The brewing process of Guizhou rice wine was analyzed,an automatic rice wine brewing device was designed in combination with the brewing process,the overall design of the device was completed,the drawings of the automatic rice wine brewing device were drawn,and the device was processed.(2)Simulation analysis of the heating temperature field of the conical fermenter,to study the effect of heating the fermentation liquid from the lower part on the heating temperature distribution of the fermentation liquid,and to compare and analyze the experimental data.The simulation results are basically consistent with the experimental results.The heating process temperature There is a problem of uneven temperature distribution in the vertical direction inside the fermentation tank,and the fermentation temperature cannot be effectively controlled.Therefore,an improved scheme was proposed for the original fermentation scheme,and the simulation analysis was carried out,and it was concluded that the heating scheme from the wall surface was more reasonable,and it was easy to achieve uniform temperature distribution in the tank,and the optimal design of the fermentation tank was completed.(3)The control strategy and dynamic simulation of the temperature control system of the flowing wine are completed.A mathematical model of the temperature control system of the flowing wine system is established.Compared the dynamic simulation effect of PID and fuzzy PID control methods,the fuzzy PID control effect is better,and it is considered that the fuzzy PID is more suitable for the temperature control system designed in this paper.(4)The on-site automatic control system and touch screen HMI configuration of the rice wine automatic brewing device are designed,and the design of on-site control and human-computer interaction interface is completed.A remote monitoring system,mobile phone APP and web master station browsing are designed to provide enterprise system operation monitoring and data storage means.(5)After completing the installation and debugging of the device,several production tests were carried out.The indicators of the rice wine produced are all qualified,and the device is considered to have a certain advanced nature.The comparison between the brewing using the automatic rice wine brewing device and the traditional process is analyzed.The automatic rice wine brewing device has many advantages,which can help the brewing industry to upgrade and update the equipment and improve the stability of product quality. |
