Pneumatic technology in the development of food packaging machinery

Pneumatic technology to achieve automation and mechanization of the production process is one effective means, with high speed and efficiency, clean and safe, low cost and easy maintenance, it is widely used in the field of light machinery, in Food Packaging And the production process is also playing an increasingly important role.

In the food zone and splash zone applications, a typical pneumatic products Figure 1 in the food zone and splash zone applications, a typical pneumatic products: stainless steel cylinder, cylinder-type cleaner, easy to clean valve island, such as stainless steel filter and regulator

Food packaging machinery in China after nearly 20 years of development, has formed a certain scale, as Machinery Industry Important part. Now most of the domestic food processing packaging, especially the more basic or complex manual packaging process, which most likely caused by contamination of the packaged products, this state of extreme need of change. At present, the state has increased efforts to implement food quality and safety market access system, food packaging equipment are also being gradually incorporated into food quality and safety access system, which is food packaging machinery industry to achieve a good opportunity for upgrading. Modern food packaging machinery is a collection of various disciplines of advanced technology, high efficiency, high accuracy, high automation and high flexibility of features, and intelligent and integrated forward direction, which is one of basic aerodynamic technology elements .

Pneumatic automation and production process technology is an effective means of mechanization, with fast and efficient, clean and safe, low cost and easy maintenance, it is widely used in light industry machine in the field, in food packaging and the production process also is playing an increasingly important role. In various Packaging Machinery In the large number of applications, can reduce the processing overhead time, reduce the labor intensity, high-performance full play equipment.

However, food packaging machinery to meet Food Machinery Safety-related requirements and regulations, and general working environment of the scene is relatively complicated harsh, if you use an inappropriate pneumatic components, often unusual phenomenon. The modern food packaging machinery, usually set the machinery, Electric , Hydraulic and pneumatic technology, and between the various parts and is inextricably linked to, any part of the equipment failure will affect the normal work. Thus, in food packaging machinery design and application of pneumatic parts, we must use reliable products that meet the actual needs.

British Norgren easy to clean the VM series valve islands In food production, different production areas of the health requirements are different. Europe EN1672-2 standard will Food Processing Machinery The environment is defined as the three work areas, namely food zone, splash zone and non-food areas. According to different areas of health requirements, required the use of pneumatic technology and products are not the same.

Food zone and splash zone safety and health requirements In the food zone and splash area, pneumatic technology is mainly used for distribution, bottling, forming, filling, dispensing and sealing devices, pneumatic components as needed, directly or indirectly with the main production Raw material Contact, in order to avoid pollution of the final product, the materials should be non-toxic, non-absorbent and corrosion resistant stainless steel original. If you use the aluminum material, should have some corrosion resistance, non-toxic, non-absorbent. Components used within such as seals and other rubber products should comply with relevant health requirements, should have the heat, acid and oil and other characteristics, acceptable normal cleaning and disinfection, does not dissolve, non-toxic and non-absorbent, may not affect the product odor. Work shall be guaranteed against the air filter dust by more than 5 m, structure and surface should be smooth, durable, and easy to clean and wash to achieve a good result. Although the splash zone design needs and food areas were similar, but the material requirements can be reduced, where appropriate, and must ensure that the design was no negative impact on food products.

Applications in both environments typical of pneumatic products, stainless steel cylinder, cylinder-type cleaner, easy to clean valve island, stainless steel filter and regulator, etc. (Figure 1), of which the most representative is the clean-type cylinder, such as the UK Norgren's PVA series clean type cylinder. This cylinder clean design eliminates food particles may adhere to the cavity, crevice and sharp corners, with self-drainage, so the liquid can drain off. The material of anodized aluminum cylinder, hard contact plated stainless steel rod, the use of seals for the polyurethane material, the cylinder as a whole meet the requirements of IP67, only corrosion-resistant, but also to repeated washing. In addition, the cylinder is in line with ISO6431 standard products, with the substitution is even install the parts are also used standard parts, installation and maintenance are very convenient.

Norgren pneumatic triple the company's intelligent documents Non-food area the size of components increasingly demanding In non-food areas, pneumatic technology is mainly used for sealing bags, packaging, labeling, testing and stamping and other devices, even though the region does not need access to raw materials pneumatic component, but usually still need to have standardized, easy to clean intelligent environmental protection and compact structure. As the current food packaging equipment requirements in the limited space, more functionality, so the size of pneumatic components for the increasingly stringent requirements. Figure 2 shows the typical products include the British Norgren easy to clean VM series valve islands, the width of only 10mm the body can provide 430L/min flow, can be 2 to 20 integrated, and in accordance with IP65 and food packaging in the complex control trend. In addition, the advanced food packaging equipment commonly used by the filter, regulator and non-oil lubricating the valve and cylinder composed of a lubrication-free pneumatic system, which components need lubrication Department in pre-sealed grease, no oil fog, which can be long working hours without added grease, reduces fuel consumption and cost, improve the environment, easy maintenance and stable performance.

Intelligent pneumatic device With increasing food processing technology, food packaging automation level is rising, the current research and development of food packaging machinery is moving in high speed, multi-functional intelligent direction and control, industrial robotics, microelectronics, computers, intelligent and image sensor technology will be more widely used, and used in food packaging machinery, pneumatic technology and network intelligence will become inevitable.

Intelligent cylinder is a master of intelligent cylinder to Norgren's intelligent cylinder, for example, that the cylinder valve and built-in speed
