With the prosperity of China's commodity economy and the improvement of people's living standards, the prospects of food packaging machinery packaging technology are very optimistic. In recent years, the state has increased its supervision of the quality and safety of food and medicine, and has put forward new requirements for the production, processing and packaging technology of food. A group of food production enterprises have invested in the technological transformation of packaging equipment and innovation of production technology, which has improved the level and market competitiveness of China's food industry to a certain extent. Although the level of China's food packaging machinery packaging technology has improved, China's food packaging machinery packaging technology is still significantly weak compared with developed countries. About 30% of enterprises in China's packaging machinery industry have low-level redundant construction. This situation not only wastes limited resources such as capital and manpower, but also causes disorderly chaos in the packaging machinery market, hinders the healthy development of the industry, and restricts the upgrading of packaging machinery and the innovation of packaging technology in China's small and medium-sized food enterprises.
China's food packaging machinery is mostly based on single machine, with low technology content and low degree of automation. It is less applied in new technologies, new processes and new materials, and cannot meet the requirements of China's current food enterprise development. In order to carry out technological transformation, some food enterprises have to spend a lot of money to introduce some complete sets of food packaging production lines with advanced technology, high production efficiency and high packaging precision, resulting in a large part of the domestic market share being occupied by foreign brands. The development space of food packaging machinery in China is still broad, and the level of food packaging machinery packaging technology needs to be improved.
Looking for gaps between domestic machinery and international technology
The production efficiency is low, the energy consumption is high, the stability and reliability are poor, the product shape is backward, the appearance is rough, the basic parts and the accessory parts have low life, and the domestic pneumatic parts and electrical components are of poor quality. For example, Henan Xinghuo Packaging Machinery Co., Ltd. is carrying out transformation and innovation on the basis of foreign advanced packaging machinery technology. The pneumatic parts of the Xinghuo brand filling machine adopt the pneumatic components of German FESTO and Taiwan AirTac.
Control technology is used less. Such as remote control technology, stepper motor technology, information processing technology. Experts pointed out that the world's packaging machinery level in Germany, Italy, the United States and Japan is in a leading position. Among them, the technology of forming, filling and sealing three kinds of mechanical equipment in the United States is very fast. For example, the liquid filling machine produced by American Liquid Filling Equipment Company (EJF) can realize gravity filling, pressure filling and positive pressure moving pump filling. That is to say, any viscosity liquid can be realized by changing the filling method by microcomputer control. In recent years, this technology has appeared in China, such as Jiangsu Qunjie Packaging Machinery Factory and Guangzhou Aote Packaging Machine Company.
Learning from the advanced methods of foreign packaging machinery
German packaging machinery is world-class in terms of metering, manufacturing and technical performance. The beer and beverage filling equipment produced in the country is fast in production, high in automation and reliable. Mainly reflected in: automation of the process, high production efficiency, meeting the short delivery time and reducing the cost of the process; the equipment has higher flexibility and flexibility. Mainly reflected in the flexibility of production, the flexibility of construction and the flexibility of supply to meet the needs of product upgrading;; using computer and simulation technology to provide complete sets of equipment, low failure rate, can be used for remote diagnosis services; Less environmental pollution, mainly including noise, dust and waste pollution.
40% of the packaging machinery produced in Italy is food packaging machinery, such as candy packaging machines, tea packaging machines, filling machines, etc. The product is characterized by exquisite appearance, excellent performance and low price. The biggest advantage of the Italian packaging machinery industry is that it can be designed and produced according to the requirements of users, and can ensure the design, production and testing are well completed, and supervision, inspection, assembly, adjustment and user demand analysis are realized.
Japan's food packaging machinery, although mainly small and medium-sized single machine, but the equipment is small in size, high precision, easy to install, easy to operate, and high degree of automation.
With the development of science and technology in the world, developed countries have integrated nuclear energy technology, microelectronics technology, laser technology, biotechnology and systems engineering into traditional mechanical manufacturing technology. New materials such as new alloy materials, polymer materials, composite materials and inorganic non-metallic materials have also been promoted and applied. The integration, intelligence, networking and flexibility of food packaging machinery will become the mainstream of future development.
