Summary of the development of China's food and packaging machinery industry (Part 2)

problems in China's food packaging machinery

1 There is a big gap with foreign products

China's food and packaging machinery industry has made remarkable achievements in recent years, but there is still a 20-year technical gap compared with foreign products. The technical content of some packaging machinery products in China is not high, but many advanced technologies have been applied to packaging machinery abroad, such as remote control technology (including monitoring), stepping motor technology, automatic flexible compensation technology, laser cutting technology, information processing technology, etc. Domestic production is mostly single machine, while foreign production is mostly supporting, and few single machine sales. The reliability of products is poor, the speed of technology updating is slow, and the application of new technologies, new processes and new materials is few. China's food and packaging machinery has more single machines, less complete sets, more general-purpose models, less equipment that meets special requirements and special materials. There are many products with low technology content and few products with high technology added value and high productivity; Intelligent equipment is still in the development stage. The quality gap of China's food and packaging machinery products is mainly manifested in poor stability and reliability, backward modeling, rough appearance, short service life of basic parts and accessories, short trouble free operation time, short overhaul cycle, and the vast majority of products have not formulated reliability standards. At present, only 5% of China's food and packaging machinery has reached the level of foreign countries in the 1990s, 20% has reached the level of the 1980s, and 60% has reached the level of foreign countries in the 1970s. Compared with industrialized countries, China has 30-40% fewer varieties of food and packaging machinery products, and its technical level is 20-30 years behind

2. Repeated construction is serious

food and packaging, in which a is the size of the machinery industry composed of mold parts. Low level repetition refers to the phenomenon of repeatedly producing machinery products with low cost, relatively backward process level and easy to manufacture, regardless of the requirements of industry development. At present, China's food and packaging machinery market is full of machinery products with low cost, relatively backward process level and easy to manufacture. If such a market environment cannot be improved for a long time, it will not be conducive to the upgrading of products in the whole industry. Specific and accurate data have not been counted yet. At present, about 1/4 enterprises in the industry have low-level repeated production, and about 1000 enterprises are producing at low-level repeated production

there are more than 100 automatic sealing machines with relatively elementary technology in Wenzhou alone; There are still enterprises producing the code printer with simple process, and the production of hot code printer has been cancelled by the state at present; The electric baking machine has been very primitive, but there are still many manufacturers; Despite the problems of oil filtration and oil change, there are still manufacturers producing fried dough sticks because there are markets in rural areas and small towns; Filling and capping machinery and some primary products are still produced; The production of relatively primary dough pressing machines is also continuing. The main reasons for low-level repeated production are as follows: low-level products have low scientific and technological content, simple manufacturing process, and require less investment; The scientific research and innovation ability of enterprises is seriously insufficient, and the updating speed is too slow; Enterprises have not applied for patent protection for new products developed by themselves in time

if this low-level repetition is not controlled, low-level and low-grade products will be produced continuously, causing a great waste of resources; At the same time, a large number of such products flooded the market, resulting in the chaos of the machinery market, so that legitimate intellectual property rights can not be effectively protected, hindering the continuous upgrading and innovation of industrial products, and ultimately hindering the social and economic development

3. Insufficient development capacity

China's food and packaging machinery is mainly imitation and mapping, with a little localization improvement, there is no development and research. At present, the domestic investment in scientific research and development is relatively small. According to the regulations, the technical investment can account for 3% of the sales revenue, but most enterprises cannot do so. Our development means are backward. Now better enterprises have carried out the "plate rejection project", but few really use CAD. Lack of innovation in product development makes it difficult to improve. The production means are backward, and most of them are processed with obsolete general equipment. New product development is not only a small number, but also a long development cycle. In terms of enterprise management, it often pays attention to production and processing, ignores research and development, and innovation is not enough, so it can not provide products in time to keep up with market demand. Most enterprise technicians account for less than 10% of the total number of employees. Only a few enterprises can achieve an annual output value of more than 50million yuan

4. Weak awareness of intellectual property rights

China's food and packaging machinery industry is lack of awareness of intellectual property rights, and has not applied for patent rights for new products developed by itself in time to protect them. Often, a product of an enterprise has just been developed and put on the market, and other enterprises soon copied it. Thousands of enterprises have put the same device product on the market at the same time in a short time, and in the end, there is no developer of the device product at all; Or even if developers want to pursue other imitation manufacturers, they have to end up without applying for intellectual property protection. In China, the updating speed of load sensor force measurement, microcomputer display experimental force and experimental curve mechanical products of food and packaging machines is too slow to catch up with the speed of repeated production at low waiping. Many enterprises are busy expanding the market for their existing products Busy copying and plagiarizing other people's equipment products, without considering how to upgrade mechanical products and how to realize technological innovation

development trend of food packaging machinery

at present, the competition of international packaging machinery is becoming increasingly fierce. In the future, food packaging machinery should cooperate with the trend of industrial automation and work in the following four directions:

1 Experts believe that by 2005, the production concentration of the top 50 enterprises can reach 50% - 60%, and continue to develop towards scale and collectivization in order to pursue economies of scale. However, small and medium-sized enterprises should not blindly introduce production lines under the current situation of insufficient capital and technical strength, but can adopt the mode of providing spare parts production for large machinery enterprises. At present, in addition to the certain scale and advantages of corrugated box packaging machinery and some small packaging machines, other packaging machinery in China is almost out of system and scale, especially some complete packaging production lines with large demand in the market, such as liquid filling production line, beverage packaging container equipment, sterile packaging production line, cigarette packaging production line, etc., are monopolized by several large packaging machinery enterprises (groups) in the world packaging market. As foreign enterprises enter the Chinese market, some uncompetitive domestic packaging machinery enterprises will be acquired, merged or bankrupt by domestic and foreign enterprises, and some packaging products will be monopolized by several large enterprises, and the scope of monopoly will gradually expand from cigarette and beverage packaging machinery products to other packaging machinery products

2. Specialization of parts production

the international packaging industry attaches great importance to improving the general ability of food packaging machinery processing and the whole packaging system, so the specialization of food packaging machinery parts production is the inevitable trend of development. After the uproar, many parts are no longer produced by packaging machinery factories, but by some general standard parts factories, and some special parts are produced by highly specialized manufacturers. This is because many control components or structural components of packaging machinery are the same as general equipment and can be borrowed. At present, the pattern of "small and complete" and "large and complete" in China's packaging industry should be adjusted as soon as possible

3. The technology of intelligent packaging has been put into use in the United States, France and other places. Food technology researchers estimate that 20% to 40% of food packaging will apply intelligent packaging technology in the future. Intellectualization can more effectively protect the quality of food, or directly display whether the food is fresh, so that consumers do not have to wait until after unpacking to find out whether the food has gone bad. For example, in order to delay the deterioration of food due to oxidation, the current common practice is to put an iron powder packet in the package, and use the iron oxidation process to consume the oxygen in the package. But some customers don't work hard when they see a small package with the word "don't eat" printed in the food, and the new package is to add a layer of "oxygen absorbing" material to the packaging paper, which can make them feel much more comfortable. Some fresh-keeping foods need to be preserved at low temperature, otherwise the bacteria in them will become active, leading to food deterioration. Put a new label on the package that can indicate the time and temperature, and the chemical components will polymerize when the temperature rises, and the color of the label will change accordingly. From this, customers can know the temperature at which the food is stored, how long it has been stored, and how fresh it is

at present, some companies in the United States are developing fresh-keeping instruction packaging for frozen food. The new packaging can monitor the gas released by meat, fish or vegetables due to improper freezing and decay. Different fruits and vegetables require different concentrations of oxygen and carbon dioxide, and packaging technology for this feature is also being developed. A company in California is developing a packaging film, which can change its permeability with temperature to meet the different needs of different fruits and vegetables for oxygen and carbon dioxide. In New Zealand, researchers are developing a kind of fruit packaging, which can indicate when fruits like peaches that are afraid of being squeezed and pressed are ripe

4. Develop towards refinement and specialization

in the future, the development direction of China's food packaging machinery industry is refinement and specialization. Relying on simple repetition, expanding the production quantity, and extending to the upstream and downstream is not feasible. China's packaging machinery industry must take the road of professional production. We should develop medium and high-end equipment, strive to improve the content of wear and scratches on the surface of some parts caused by technological inequality, refine, refine, specialize and strengthen products, and promote the development of the industry by technological progress. At present, countries all over the world attach great importance to the development of packaging machinery, and high-tech products integrating machinery, electricity, gas, light, biology and magnetism continue to emerge. High efficiency of production, high utilization of resources, energy conservation of products, practicality of high-tech and commercialization of scientific research achievements have become the development trend of packaging machinery all over the world, which is also the development direction of China's packaging machinery industry. Therefore, experts believe that China's packaging machinery manufacturing enterprises should not seek perfection, but refinement and expertise
