Abstract: This paper introduces the current situation of automatic decocting and aseptic packaging of traditional Chinese medicine at home and abroad. By analyzing the decocting mechanism of traditional Chinese medicine and combining modern mechanical and electrical manufacturing technology, an integrated machine for automatic decocting and aseptic packaging of traditional Chinese medicine is designed, and the process flow, working principle and structure of each component of the machine are analyzed in detail, It has laid a good foundation for further application and popularization

1. Overview

Chinese traditional medicine has a long history and has made great contributions to human health for thousands of years. With the deepening of the research on traditional Chinese medicine, he attracts more and more people to see traditional Chinese medicine with his unique charm. In China, almost every hospital has a TCM clinic. People usually turn to TCM for help for difficult and miscellaneous diseases. The patient takes the prescription home and decocts it after dispensing it according to the prescription of the traditional Chinese medicine doctor in the traditional Chinese medicine pharmacy. The traditional decocting method of traditional Chinese medicine is very particular, and has a great impact on the curative effect of traditional Chinese medicine. However, it is difficult to grasp the boiling process and heat. From the appliance to the heat, it is fried first and then taken. It takes time to boil, and it is very inconvenient to take and carry, which is extremely unfavorable to the development and promotion of traditional Chinese medicine. How to realize the modernization of traditional Chinese medicine when the convenient, healthy and efficient lifestyle has become the goal of people? How to realize the long cherished wish of Chinese people to let traditional Chinese medicine rush out of the country to the world? This is an urgent task before us. The development of traditional Chinese medicine decocting and aseptic packaging machine meets the needs of people's fast-paced life, is a good way to solve this problem, and has important practical significance

the research on traditional Chinese medicine and its automation equipment is mainly concentrated in the surrounding countries and regions of China. Japan is a country with the longest history, the widest range, the highest level and the largest number of practitioners of traditional Chinese medicine

the research on the basis of traditional Chinese medicine and its equipment in Korea is also very active. Its focus is to improve the modernization level of the developed traditional Chinese medicine through the basic research work of traditional Chinese medicine, so as to obtain economic profits. Especially in the research of traditional Chinese medicine decocting method, (3) some achievements have been made in the pen and paper with automatic plotter. After learning from the Chinese traditional Chinese medicine decocting and formula making methods, South Korea took the lead in developing traditional Chinese medicine decocting equipment and sterile packaging machine in the world. In recent years, a small amount has been exported to China, which has been immediately welcomed by many large and medium-sized city hospitals, and has benefited 4 The utility model can effectively avoid the slipping of the jaw when the clamped sample is stretched, and the utilization rate is high, and the market prospect is promising

therefore, Chinese medical equipment manufacturers began to research and copy this equipment. Through investigation and research, we found that there are many problems in the current domestic equipment: blindly copying foreign equipment, the decoction process of traditional Chinese medicine often has an impact on the drug properties, the automation control is not ideal, and the aseptic packaging performance is unstable

looking at the current research situation at home and abroad, we believe that it is necessary to conduct in-depth research on the boiling mechanism of traditional Chinese medicine in theory, integrate theory with practice, learn from foreign advanced technology, and learn from the experience and lessons of domestic enterprises, so as to design an integrated, miniaturized and automated traditional Chinese medicine boiling equipment and its sterile packaging machine to meet the needs of the domestic market. See Fig. 1 for the process diagram of the tank machine integrated traditional Chinese medicine and sterile packaging machine

1 - safety valve; 2 - electric extrusion rod; 3 - pressure transmission display alarm; 4 - filter barrel; 5 - boiling pot; 6 - temperature transmission display alarm; 7 - solenoid valve; 8 - electric heater; 9 - horizontal cutting; 10 - horizontal seal; 11 - longitudinal sealing and traction; 12 - left and right packaging film rollers; 13 - flow regulating valve; 14 - liquid level transmission alarm; 15 - cleaning solenoid valve of packaging machine; 16 - liquid medicine container; 17 - exhaust port; 18 - tank cleaning solenoid valve; 19 - pressure relief solenoid valve

2. Process description

before start-up, sterilize the entire equipment piping system with steam for 30min; The equipment cavity is sprayed with H2O2 water mist for sterilization for 25min; The second is soaking. Before decocting the medicine, soak the medicine in clear water for 30min to soften it, and then heat it for decocting. It is not allowed to directly use the axle split control multi-functional experimental machine. It is a material testing equipment with domestic new technology. Otherwise, the protein in the medicine will soon solidify, affecting the decocting of the effective components in the traditional Chinese medicine

open the head of the decocting pot and add Chinese medicine and water into the decocting pot 5; Before switching on the power supply, set the temperature controller and liquid discharge timer on the PLC (usually at 120 ~ 125 ℃, the time is set as 1H; when switching on the power supply, keep the temperature at 120 ~ 125 ℃, and the pressure at about 1.5 ~ 1.7bar (Note: in fact, there may be errors of ± 10 ℃ and ± 0.5bar, due to the influence of different medicinal materials, different decocting capacities and the thickness of the manually made internal heating plate); When discharging the chemical solution, the solenoid valve 7 automatically opens to release 0.5bar of steam. (in order to better discharge 2. Classification of natural bio based high molecular materials and introduction of liquid medicine). In order to prevent overheating, the safety valve 1 on the head will automatically vent when the pressure exceeds 2bar; After the above process, the solenoid valve 7 opens automatically, and the liquid medicine flows through the pipeline to the liquid medicine container 16 under its own pressure. At the same time, the electric extrusion rod 2 rotates until it stops and slowly locks to ensure that all the liquid medicine flows out; Then, the liquid level transmission alarm 14 starts the automatic bag packing of the packaging machine; The sterile packaging area is filled with sterile hot air and irradiated by ultraviolet lamp to ensure that the filling and sealing of the liquid medicine are carried out in a sterile state.
