The development of food packaging machinery in Chi

  • Detail

The development of China's food packaging machinery is not commensurate with the needs of the industry

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 technology 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. 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 food and packaging machinery products in China is mainly manifested in poor stability and reliability, backward shape, rough appearance, short service life of basic parts and supporting parts, short trouble free operation time, short overhaul cycle, and the vast majority of products have not yet issued and formulated reliability standards. At present, only 5% of China's food and packaging machinery have reached the level of foreign countries in the 1990s, 20% have reached the level of the 1980s, and 60% have reached the level of foreign countries in the 1970s. Compared with industrialized countries, China has 30 to 40% fewer varieties of food and packaging machinery products, and its technical level is 20 to 30 years behind

serious repeated construction

low level duplication in the food and packaging machinery industry refers to the phenomenon of repeatedly producing mechanical products with low cost, relatively backward process level and easy to manufacture regardless of the development requirements of the industry. 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 many enterprises producing simple process coding machines. The production of hot coding machines has been cancelled by the state, but some enterprises still go their own way; 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; Primary products such as filling and capping machinery are still in production; The production of relatively primary dough pressing machines is also continuing. The main reasons for low-level repeated production are as follows: the product requires 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. This low-level repeated coherent technical index requires a comprehensive and more targeted phenomenon. If it is not controlled, 5) device test pieces will cause a large number of such products to flood the market and cause a great waste of resources; At the same time, it will cause chaos in the machinery market, make intellectual property rights not effectively protected, hinder the continuous upgrading and innovation of industrial products, and eventually hinder the social and economic development

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 Convention, the technical investment can account for 3% of the sales revenue, but most enterprises cannot do so. The development means are backward. Now better enterprises have carried out the "plate rejection project", but few really use CAD. Most enterprise technicians account for less than 10% of the total number of employees

weak awareness of intellectual property rights

China's food and packaging machinery industry lacks awareness of intellectual property rights, and has not applied for patent protection in time for new products developed by itself. Often, an enterprise's open formula modification can actively calculate the force, stress, displacement, deformation and other data results at any specified point in the experimental process. A new product has just been put on the market, and other enterprises soon copied it. Thousands of enterprises have launched the same equipment product at the same time in a short time, and in the end, they can't even find the developer of the equipment product at all; Or even if developers want to pursue other imitation manufacturers, they have to end up without applying for intellectual property protection

development trend of food packaging machinery

at present, the competition of international packaging machinery is increasingly fierce. In the future, the production of food packaging machinery will be automated, and efforts will be made in the following four directions:

1. The market is increasingly monopolized

experts believe that by 2005, the production concentration of the top 50 enterprises can reach 50%-60%, and continue to develop towards large-scale and collectivization in order to pursue economies of scale. However, small and medium-sized enterprises should not blindly introduce production lines under the condition 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 companies (groups) in the international packaging market. As foreign enterprises enter the Chinese market, some uncompetitive domestic packaging machinery enterprises will be acquired, merged or bankrupt, 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 universal ability of food packaging machinery processing and the whole packaging system, so the specialization of food packaging machinery parts production is an inevitable trend. 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. Develop towards intelligence

the technology of intelligent packaging has been widely used in the United States, France and other countries. Food technology researchers estimate that 20% to 40% of food packaging machinery 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 it in the package. Then how to solve these problems is the key. Put an iron powder bag, and use the oxidation process of iron to consume the oxygen in the package. However, some customers don't feel quite right when they see a small package printed with the word "don't eat" 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 brightness and temperature, and the chemical components will polymerize when the temperature rises, and the color of the label will change light and dark with the temperature, so that customers can know what temperature the food is stored at, 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. 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. Strive for excellence and expertise

in the future, the development direction of China's food packaging machinery industry is to strive for excellence and expertise. 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 technical content, refine, specialize and strengthen our products, and rely on technological progress to promote the development of the industry. 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, sound 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, China's packaging machinery manufacturing enterprises should not seek perfection, but refinement and expertise
