The imported equipment is not domestically manufactured or the manufacturing level is very different. From the import, we can see that our gap lies.
Food safety issues are of national concern. During the "Eleventh Five-Year Plan" period, we should improve the level of science and technology and equipment in the field of food safety, develop technologies and equipment for quickly and accurately identifying hazard factors in food, and further develop prevention technologies and storage technologies and equipment for the control of pathogenic microorganisms, control of pathogens. .
The food and packaging machinery industry has been in the industry for 20 years, and it is still a new industry compared to the food industry. These 20 years are the fastest period of technological development in the world. New technologies are constantly being applied in the industry. The foundation of the domestic industry is weak, and the strength of technology and scientific research is insufficient. Its development is relatively lagging behind, dragging the food and packaging industry to some extent. The hind legs. Although the overall development is faster, the food and packaging industry is growing faster. It is predicted that the total output value of the food and packaging machinery industry will be about 62 billion yuan at the end of 2005, while the domestic market demand will reach 85 billion yuan. By 2010, the total output value of the domestic industry can reach 130 billion yuan (current price), and market demand may reach 200 billion yuan. The space in this market will be filled with foreign equipment. The goal of the "Eleventh Five-Year Plan" is to narrow this space and catch up with the world's advanced level for the food industry. In order to make the packaging powers move toward the packaging powers, we will provide advanced technology and equipment, so that imported equipment will only be used to fill the gaps in the domestic market. effect. This requires that the annual development rate of domestic food and packaging machinery exceeds 18%, and the output rate of new products reaches 25%.
The development of packaging and food machinery in the world is aimed at the requirements of major customers and drives the development of related machinery. The requirements of major customers are mainly reflected in the following aspects:
First, the higher the requirements for production efficiency, the better. This can reduce the cost of the product and meet the delivery date. The high-speed packaging machine needs to be connected with the previous process. There is no need to carry out the process, including the control connection. The entire production line is arranged in reverse order according to the production and packaging process, and the sequence is stopped. For example, the cold filling production line is automatically brought online from the plastic raw materials to the beverage filling and the large packaging yards are automatically carried out in the closed workshop.
The second is to adapt to the changes in the product. Packaging machinery requires a high degree of flexibility and flexibility, and the production line allows the size of the package to vary within a certain size range. Because the life cycle of the product is much shorter than the service life of the equipment, changing the product and packaging does not replace the expensive packaging production line.
Third, the common faults of the equipment are quickly eliminated. The solution is pre-entered into the computer. When the device has a common fault, it can be diagnosed by itself, and remote diagnosis and troubleshooting can be performed.
Fourth, it is required to have automatic identification. On the one hand, it can automatically identify the thickness, hardness, rebound force, etc. of the packaging material, and feedback to the robot through the computer to adjust the range of motion to ensure no rebound. On the other hand, a variety of different products, such as chocolates or snacks of various shapes, are placed in the same box, and the arrangement is regular. The products delivered by the production line are disordered. The probe can be scanned to determine the position of materials with different shapes, and then fed back to different robots. It will accurately put the items into the tray according to the exact position and direction, fast and accurate. Manual manipulation of vision and finger fatigue.
Fifth, it can minimize environmental pollution. Reducing noise, dust pollution, and minimizing waste is especially important in food processing. In the processing of food raw materials, not only the main products, such as corn processing, in addition to corn starch, corn oil, salad oil, margarine, glucose, corn protein and feed, as well as sewage treatment and other production processes are automated. Without waste, no pollution, the value of other products has greatly exceeded the value of corn starch.
At present, a prominent problem in China's food and packaging machinery is that the new product development cycle is long, the imitation is more, and the innovation is less. This is not only related to the knowledge level of the designers, but also related to the development of related industries.
The internationally advanced method is to use simulation technology to automatically synthesize a three-dimensional model from a computer, and input the fault data of the production line that has happened in the past into the computer to demonstrate the actual working conditions and modify it in front of the user as needed. The computer synthesis speed is fast, and the modification work is quick and convenient. If some requirements of the user are not met, the computer will tell you to exempt the disputes in the future. The simulation technology completed by the computer shortens the design cycle of the packaging machine (production line), and the satisfaction of the customer is greatly improved.
