Development trend of food filling machinery technology in China

At present, most of China's food packaging enterprises are small in scale. “Small and complete” is one of its main characteristics. At the same time, regardless of the development requirements of the industry, there are repeated production of mechanical products with low cost, relatively low level of technology and easy to manufacture. About a quarter of the companies in the industry currently have low levels of repetitive production. This is a great waste of resources, causing confusion in the packaging machinery market and hindering the development of the industry.

The annual output value of most enterprises is between several million yuan and 10 million yuan, and the number of enterprises below 1 million yuan is still quite a lot. Nearly 15% of enterprises change or close down each year, but 15% of them join the industry, which is extremely unstable, which hinders the stability of the industry.

With the continuous development of science and technology, the emergence of various food and aquatic products has put forward new requirements for food packaging technology and equipment. At present, the competition for food packaging machinery is becoming increasingly fierce. The future food filling machinery will cooperate with industrial automation, promote the overall level of packaging equipment, and develop multi-functional, high-efficiency, low-consumption food packaging equipment.

Realizing mechanical and electrical integration of food filling machinery

Conventional filling machines mostly use mechanical control, such as cam distribution shaft type, and later control forms such as photoelectric control and pneumatic control. However, with the increasing improvement of food processing technology, the requirements for packaging parameters are increasing, the original control system has been difficult to meet the needs of development, and new technologies should be used to change the appearance of food packaging machinery. Today's food filling machinery is a mechanical and electronic equipment integrating machine, electricity, gas, light and magnetism. When designing, we should focus on improving the automation degree of packaging machinery, combining the research and development of packaging machinery with computer to realize electromechanical integration. Control.

The essence of mechatronics is to use the principle of process control from the system point of view to organically combine mechanical, electronic and information, testing and other related technologies to achieve overall optimization.

Generally speaking, it introduces microcomputer technology into packaging machinery, applies electromechanical integration technology, develops intelligent packaging technology, combines into automatic packaging system for production according to product automatic packaging process requirements, detection and control of production process, diagnosis of faults and Elimination will achieve full automation, achieving high speed, high quality, low consumption and safe production. It can be used for precise metering of aquatic products, high-speed filling and automatic control of packaging process, which will greatly simplify the packaging machinery structure and improve the quality of packaging products. For example, the most common plastic bag sealing machine, its sealing quality is related to packaging materials, heat sealing temperature and running speed. If the material (material, thickness) changes, the temperature and speed will change accordingly, but it is difficult to grasp the change. If the microcomputer control is used, the optimal parameters of the sealing temperature and speed of various packaging materials are matched into the microcomputer memory, and then the necessary sensors are combined to form an automatic tracking system, so that no matter which process parameter is changed, the best is guaranteed. Sealing quality.

Adopting new technology to establish a new packaging machinery system with automation, diversification and multi-functional integration

The technical development trend of food filling machinery is mainly reflected in high productivity, automation, single machine multi-function, multi-functional production line and new technology. Such as: multi-station bag vacuum packaging machine, its bag making, weighing, filling, vacuuming, sealing and other functions can be completed on a single machine; several machines with different functions and matching efficiency can be combined into functions. A more complete production line, such as the fresh fish vacuum packaging production line developed by France CRACECRYOYA and ISTM. With the relevant new technology, a large number of inflatable packaging is used to replace the vacuum packaging in the packaging method, and the research on the three aspects of the inflatable component, packaging material and the air-packing machine is closely combined; in the control technology, more application of computer technology and microelectronic technology .
