Current situation and trend analysis of the hottes

The current situation and trend analysis of food and beverage packaging automation

in the first three years of the tenth five year plan, China's food industry developed rapidly, with a growth rate of% and the dairy industry, fruit juice and beverage industry reached a growth rate of 30% in 2003

in 2003, the sales volume of Enterprises above the limit (more than 5million yuan) in the food industry reached 1233 billion yuan, and the sales volume of enterprises below the limit was more than 10000 billion yuan. The sales of food and packaging machinery is only 46billion yuan, which is far from meeting the domestic demand in the next three years. The total import is 2.294 billion dollars, and the total domestic market demand is 65billion yuan

in recent years, the imported equipment can not be manufactured domestically or the manufacturing level is far from it. The import really represents our gap

food safety has been concerned by the whole country. If left unchecked, it will affect people's health, reduce people's living standards, and bring serious negative effects on social stability, food industry and even the whole economic development. Therefore, 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 rapid and accurate identification of hazard factors in food, and further develop preventive technologies and storage technologies and equipment such as resistance and control of pathogenic microorganisms

as the food and packaging machinery industry has been formed for only 20 years, it is a new industry relative to the food industry. The past 20 years have witnessed the fastest technological development in the world. New technologies have been continuously applied in this industry. However, the foundation of this industry in China is weak, and the technical and scientific research forces are insufficient. Its development is relatively lagging behind, dragging down the food and packaging industry to some extent. Although the overall development is fast, the development of food and packaging industry is faster. For example, in 2003, the growth rate of food industry was 21%, while the growth rate of food and packaging machinery industry was only 16.75%, and the gap widened. If the annual growth rate is 16%, it is predicted that by the end of 2005, the total output value of the food and packaging machinery industry will be about 62billion yuan, and the domestic market demand will reach 85billion yuan. By 2010, the total output value of the domestic industry will reach 130billion yuan (current price), and the market demand may reach 200billion yuan. The hole in this market will be filled by foreign equipment. The goal of the "Eleventh Five Year Plan" is to narrow this hole, to catch up with the world's advanced level for the food industry, to make the big packaging country move forward to the powerful packaging country, and to provide advanced technical equipment, so that the imported equipment can only play a role of picking up the leftovers and filling the gaps in the domestic market. This requires the development speed of domestic food and packaging machinery to exceed 18% per year, and the output value rate of new products to reach 25% (12.97% in 2003)

the development of packaging and food machinery in the world is aimed at the requirements of large customers, so as to drive the development of related machinery. The requirements of large customers are mainly reflected in the following aspects

first, the higher the requirements for production efficiency, the better. This can reduce the cost of a single product, meet the delivery time and reduce the process circulation cost. At the same time, the high-speed packaging machine requires relevant connection with the previous process. The speed is measured with a stopwatch without handling links, including control connection. The whole production line should be started in reverse order and stopped in sequence according to the production and packaging process. For example, the cold filling production line automatically goes online from plastic raw materials to beverage filling and large package stacking in the closed workshop

second, in order to adapt to the renewal and change of products, the packaging machinery should have high flexibility and flexibility, and the size of the packaged goods can be changed within a certain size range in the production line. Because the life cycle of products is much shorter than the service life of equipment, changing products and packaging will not replace expensive packaging production lines

third, input the common faults and solutions of the equipment into the computer in advance. When the equipment has common faults, it can diagnose by itself, and can also implement remote diagnosis and troubleshooting

fourth, automatic recognition function. On the one hand, it can automatically identify the thickness, hardness, rebound force, etc. of packaging materials, and feed back to the manipulator through the computer, so that the manipulator can adjust the action range to ensure no rebound. On the other hand, all kinds of different products, such as chocolates or snacks with different shapes, are packed into the same box, and their arrangement is regular, while the products delivered by the production line are disordered. You can scan them with a probe to determine the position of materials with different shapes, and then feed them back to different robots. It will accurately put the items into the tray according to the exact position and direction, which is fast and accurate, Unlike artificial vision and finger fatigue. Fifth, minimize environmental pollution, including noise and dust pollution, and minimize waste in the production and packaging process, which is particularly important in the food processing process. During the processing of food raw materials, not only the main products are harvested, such as corn processing. In addition to corn starch, the whole production process of corn oil, salad oil, margarine, glucose, corn protein, feed and sewage treatment is automated. Without waste and pollution, the value of other products has greatly exceeded the value of corn starch

at present, a prominent problem of China's food and packaging machinery is the long development cycle of new products, more imitation and less new creativity, which is related not only to the knowledge level of designers, but also to the development of related industries

the internationally advanced method is to store various machine elements into the computer in the form of database, then input the digitized drawings into the computer, and the computer automatically synthesizes the three-dimensional model. Then input the production line faults that have occurred in the past into the computer, and complete various experiments. The computer can demonstrate the actual working conditions and modify them in front of the user according to needs. The computer synthesis speed is fast, and the modification work is fast and convenient. If some requirements of users cannot be met, the computer will also tell you to avoid future disputes. This computer simulation technology greatly shortens the design cycle of packaging machinery (production line) and greatly improves customer satisfaction

of course, the application of this simulation technology also reminds that the manufacturing of packaging machinery should first be modularized according to the functions of components. Each component has a unified interface, and each module can be freely combined. In this way, the single piece small batch production of packaging machinery can be changed into the batch production of various modules, so as to reduce the production cost

even if it is not a production line but a single machine, the modular combination can shorten the design and manufacturing cycle and reduce the production cost. Modularization can make non-standard parts standardized, make it convenient for users to troubleshoot, and reduce users' operating costs
