First, the development status of China's food machinery industry China's food packaging machinery started in the late 70s of the last century, the annual output value of only 70 million yuan, only 100 kinds of product varieties. In the past five years, the food and packaging machinery industry has grown at an average annual growth rate of 11% to 12%, which is higher than the national economic growth rate over the same period. The total sales volume has increased from 15 billion yuan in 1994 to 30 billion yuan in 2000. There were 3,700 species from 270 in 1994 to 2000.

The product level has reached a new level and the trend of scale, complete set, and automation has begun to appear. Equipment with complex transmission and high technical content has begun to appear. It can be said that China’s machinery production has met the basic domestic needs and began to export to Southeast Asia and the third world countries. For example, China’s total imports and exports in 2000 were 2.737 billion U.S. dollars, of which export value was 1.29 billion U.S. dollars, which was higher than in 1999. 22.2%. Among the exported machinery, there are many machinery exporters such as food (milk, cake, meat, fruit) processing machines, ovens, packaging, labeling machines, paper-plastic aluminum composite tank production equipment, and food machinery such as sugar, wine, and beverages. , Liquid food filling machines and other equipment have begun exporting complete sets.

Second, the world's food packaging machinery development status is still on the sales of food packaging, the most commonly used, the most basic packaging process methods, there are two major categories, namely, filling and wrapping. Filling method is suitable for almost all materials and various types of packaging containers. Specifically speaking, liquids, powders, and granular bodies that have good fluidity mainly rely on their own gravity, and they must be supplemented with certain mechanical functions to complete the packaging process. For semi-fluid or larger single pieces and assemblies with strong viscosity, corresponding mandatory measures such as extrusion, push-in, pick and place are required. As far as the wrapping method is concerned, it is different from this. It is mainly applicable to single-pieces or assemblies that are regular in appearance, rigid enough to be stiff, and require tight packing, and more flexible plastics and their composite materials (some additional Lightweight pallets, liners), wrapped by mechanical action.

In the past decade or so, the international packaging industry has attached great importance to improving the general capabilities and multi-functional integration capabilities of packaging machinery and the entire packaging system, providing timely and flexible production methods for the market to develop a rapidly changing and diverse range of goods. At the same time, based on the actual needs of rationally simplifying the packaging and superior packaging process methods, it has been continuously explored and has significantly accelerated the pace of its technological innovation. Especially with the synchronous development of modern automatic machine tools, it is gradually clear. In order to establish a new system of diversified, general-purpose, multi-functional and integrated packaging machinery, it is first necessary to focus on solving the major problems of composition and electromechanical integration. Undoubtedly, this is an important development direction in the future.

Third, the gap between China and the world's most powerful countries 1. The product variety and the quantity of complete sets of products are mostly dominated by single production machines in the domestic market, while most of the products are produced in foreign countries and are rarely sold on a stand-alone basis. On the one hand, the variety of domestic equipment can not meet the needs of domestic food and packaging companies. On the other hand, the profits of mechanized plant production and sales on a stand-alone basis are meagre, and the high efficiency of sales of complete sets of equipment cannot be obtained.

2. The low level of technology is mainly reflected in poor product reliability, slow technology update, and low application of new technologies, new processes, and new materials. China's food and packaging machinery have more stand-alone machines, complete sets, fewer general-purpose models, special requirements, and special materials. There are many low-tech products, high-tech value-added products, and low productivity products; intelligent equipment is still in the development stage.

3. Poor product quality The gap in the quality of food and packaging machinery products in China is mainly due to poor stability and reliability, backward modeling, rough appearance, short service life of basic parts and accessories, short failure-free operation time, short overhaul period, and most products. No reliability standards have yet been established.

4. Inadequate development capacity China's food and packaging machinery is still mainly imitation, mapping, a little localization improvements, not to mention development research. Our development tools have lagged behind. Now that the companies that are better have launched a “project rejection project,” there are still few people who actually use CAD. Product development lacks innovation and is difficult to achieve. Most of the production methods are backward, using the old general-purpose equipment. New product development is not only small but also has a long development cycle. In enterprise management, often heavy production and processing, light research and development, and innovation are not enough, and it is impossible to provide products timely in response to market demands.

Fourth, the future demand for food packaging machinery With the acceleration of people's daily work pace, rich nutrition and health food products, and enhanced awareness of environmental protection, the future of food and packaging will inevitably put forward many new requirements. This includes developing new technologies and new products such as vacuum packaging, vacuum inflatable packaging, and aseptic packaging according to local conditions, and organically combining it with quick-freeze packaging. Focusing on the current and future, it can be confirmed that the following three types of packaging machines are excellent models suitable for food sales and packaging, and can be said to have a long history of development and a powerful vitality of the dominant model, namely the vertical bag ( Box) forming filling and sealing machine, horizontal bag (box) forming filling and sealing machine, horizontal seam wrapping machine.

In accordance with the analysis of group technology ideas, the commonality and similarity among the three are more conducive to unified development. In addition, each has its own special differences and must be selected according to local conditions. After comprehensive comparison, the main features are as follows:

Packaging object - matching three models almost all inclusive (usually except air and liquid materials), but the third limitation.

Packaging materials - mainly reel-type composite film, in some occasions can be placed inside the second straw, the third can be placed within the ribs and other accessories.

Packing form - more than the second pattern, such as the three sides sealed bags, four sides sealed bags, double bags, stand bags, brick boxes, roof boxes, etc.; the first place second, the third less, usually Mainly pillow-shaped bags, some can be made into cylindrical bags, four sides sealed bags. Packing size - the first bag width is a minimum of 10mm, the bag length can be adjusted steplessly within the limit range; the latter two kinds of bag width and bag length can be adjusted steplessly within the limited range, of which the third one The bag can reach more than half a meter.

Sealing type - a lot of the second type of new issued, such as the upper end of the set of tear or tear line flat seal, combined with an embedded box seal, screw caps placed on different parts, etc.; the other two The models are monotonous.

Transfer movements - Both continuous and step-by-step movements can be achieved. Structural combination - fully reflects the modular structure, especially the second horizontal layout makes it easier to configure functional modules (such as vacuum pumping and nitrogen filling), plus a high degree of mechatronics to enable diversity, versatility, and multi-function integration Sexuality has been greatly enhanced to form a series of products.

Fifth, China's food and packaging machinery industry development strategy 1. The production capacity of large-scale, group-focused enterprises continues to grow towards scale and collectivization in order to pursue economies of scale. Under the current situation of insufficient funds and technical strength, small and medium-sized enterprises should not blindly introduce production lines. Instead, they can adopt the model of large-scale machinery enterprises to provide spare parts production.

2. Developing a New Situation in Product Exports China's food and packaging machinery technology is moderately priced and affordable, and it is very suitable for the economic conditions of developing countries and regions. In the future, the export prospects to these countries and regions are broad, and some of the equipment can also be exported to developed countries.

3. It is impossible to go long for improving the technological content of products without good technology as the backing for the development of the company. To achieve mechanical and electrical integration and intelligence, to the development of product information, the introduction of new technologies, and accelerate the progress of enterprise ISO9000 certification. Further improve the technical level, stability and reliability of the equipment. Courage to face the reality, actively change this state, improve product development capabilities, and form their own innovative capabilities, in order to catch up.

4. Strengthen the development of new product innovation China's food packaging machinery is mostly developed on the basis of imported equipment. For products with large gaps or gaps with foreign countries, we should actively introduce technology, digestion and absorption, and gradually grasp it until it is fully grasped. We must learn from the products that have a certain foundation but have a certain gap with similar foreign products, strengthen the research on related key technologies and core technologies, and encourage development and innovation.

5. Development of food packaging machinery with a strong demand for development With the expansion of domestic demand for packaged foods and the increase in export demand, there are currently several kinds of food packaging machinery that are in demand on the market and need to be developed.

(1) Beer and beverage filling equipment The experts believe that the complete equipment for beer filling machinery should focus on the development of medium-sized equipment with an annual output of 50,000 tons and the development of large-scale equipment with an annual output of 100,000 tons or more. The prospect of high-speed, low-loss, accurate measurement, automatic detection, and other versatile, fully automated equipment is promising. The beverage machinery should adapt to the development direction of “focusing on the production of the main agent and disperse the filled beverages” and develop technology and equipment for the deployment of beer and beverage on the spot.

(2) Convenience Food Production Packaging Complete sets of equipment The convenience food processing complete sets of equipment such as instant noodle, instant porridge, dumplings, steamed buns and other production machines are represented by a growing demand. According to the domestic market survey, the direction of people's demand for convenience foods is: there is nutritional value, the product is high-grade and delicious. The traditional food processing and market prospects for elderly and baby food processing equipment are equally promising, and related companies should focus on development.

(3) slaughtering and meat processing and packaging machinery Poultry and livestock slaughter machinery, meat processing machinery, refined meat deep processing machinery and sub-packaging machinery is the development direction. In particular, cheap shopping malls in large and medium-sized cities need to package and sell these products, and urgently need packaging machinery to be commercially available. In recent years, cities and rural areas have vigorously developed breeding and slaughtering aquaculture, and urgently need to improve the slaughtering, processing and packaging equipment for small and medium-sized poultry and livestock, purchase large-scale slaughter equipment, and develop separate processing technology equipment, packaging equipment and hams. Meat sausage and other refined processing and packaging machinery, the market prospects are quite broad.

(4) Food and edible oil deep processing and packaging market The small and medium-sized food packaging is more popular and has a large demand. The development of a series of packaging equipment suitable for different state materials and different package weights has broad prospects.

(5) Fruit and vegetable processing and preservation technology and equipment Expected future market demand for such products include: vegetable and fruit grading technology and equipment, high efficiency juice extraction technology equipment, energy-saving enrichment technology equipment, washed and selected bags of fresh fruits and vegetables and frozen The technical equipment for vegetables and dehydrated vegetables greatly reduces the processing machinery for the loss of raw materials such as fruits and vegetables, grain, meat, fish, eggs, etc., and adopts technical equipment such as gas-conditioning, Co60 radiation, and fluidized beds, as well as new practical storage and preservation technologies. Equipment, fresh fruit and vegetable processing and transportation chain equipment, such as air-conditioned fresh-keeping equipment, refrigeration and refrigerated trucks, refrigerators, kitchen refrigerators and other equipment.

The future development of China's food machinery is still in the hands of numerous companies. With the support of the government's favorable policies, enterprises can only stick to the above directions and take a long-term development path. I believe that in the near future, we can see China. New highlights of food machinery!
