Information
Pneumatic technology is one of the effective means to automate and mechanize the production process. It is widely used in the field of light industry machinery, and plays an increasingly important role in the vacuum packaging of food (including vacuum packaging of seafood and meat) and the production process. With the continuous progress of food processing technology, the level of food packaging automation is also constantly improved. The application of pneumatic technology in vacuum packaging machines for food such as seafood and meat will become an inevitable intelligent and networked.
After nearly two decades of rapid development, food packaging machinery (including food vacuum packaging machines for seafood and meat) has formed a certain industrial scale and has become an important part of China's machinery industry. At present, most of the packaging work in domestic food processing is manual operation, especially the packaging process is more complicated, which is likely to cause pollution to packaging products such as seafood, beef, salmon and other seafood. This situation needs to be changed. At present, the state has strengthened the implementation of the food quality and safety market access system, and food vacuum skin packaging equipment has gradually been incorporated into the food quality and safety access system, providing a good opportunity for the food packaging machinery industry to achieve industrial upgrading. Modern food packaging machinery is a collection of advanced multi-disciplinary technologies. It has the characteristics of high efficiency, high precision, high automation, and high flexibility. It is developing in the direction of intelligence and integration. Among them, pneumatic technology is the most basic component. one.
Pneumatic technology is one of the effective means to automate and mechanize the production process. It has the advantages of fast speed, high efficiency, safety and reliability, low cost, and easy maintenance. It is widely used in the field of light industrial machinery. It also plays an increasingly important role in food vacuum skin packaging and production processes. It is widely used in various packaging machinery, which can shorten the auxiliary processing time, reduce the labor intensity of workers, and give full play to the efficient performance of the equipment.
However, as food vacuum packaging machinery must comply with relevant food safety requirements and regulations, and requires that the on-site environment is generally relatively complex, abnormalities often occur if improper pneumatic components are used. Modern food packaging machinery is usually a combination of mechanical, electrical, hydraulic and pneumatic technologies. The close relationship between various parts, any part that fails will affect the normal operation of the equipment. Therefore, in the design and application of food packaging machinery, pneumatic parts, we must choose reliable practical needs.
In the production of food vacuum fittings, different places have different sanitary requirements. The European EN 1672-2 standard defines the environment of food processing machinery as three working areas, namely food area, splash area and non-food area. Pneumatic technology and the products used vary according to the hygiene requirements in different regions.
Food and splash areas require safety and hygiene
In the field of food and splashing, pneumatic technology is mainly used for distribution, bottling, forming, filling, dispensing and sealing equipment to avoid contamination of the final product due to the need for pneumatic components to directly or indirectly contact the main raw materials. The material should be original non-toxic, absorbable, and corrosion-resistant stainless steel. If aluminum alloy material is used, it should have certain corrosion resistance, non-toxic and non-absorption. Rubber products used in parts, such as seals, should comply with the corresponding The hygienic requirements have the characteristics of high temperature resistance, acid and alkali resistance, oil resistance, etc., and should be cleaned and disinfected normally, insoluble, non-toxic, absorbable, and no odor affecting the product. The working air filtering device should ensure that the dust is not allowed to exceed 5 μm, the structure and surface should be smooth, durable, easy to clean, and can achieve good cleaning results. Although the design requirements for the splash zone are similar to those for the food zone, the material requirements can be reduced as appropriate, while ensuring that the design does not adversely affect the food.
Typical products in these two ambient air pressure are stainless steel cylinders, clean cylinders, easy to clean, valve terminals, stainless steel filters and pressure reducing valves, the most representative of which are clean cylinders, such as clean cylinders. UK Nuoguan PVA The clean design of the series RS cylinder eliminates the cavity, gaps and sharp edges, food particles are attached, with automatic drainage function, and the liquid can flow directly. The cylinder is made of anodized aluminum, the piston rod is plated with hard stainless steel, and the seal is made of polyurethane. The cylinder as a whole meets the requirements of IP67. In addition, the cylinder and ISO6431 standardized products meet interchangeability. Even the installation of standard parts can be used. Installation and maintenance are very convenient.
Increasing sizing requirements for components in non-food areas
In the non-food field, pneumatic technology is mainly used for packaging, labeling, testing and capping equipment. Although pneumatic components in this field do not need to touch raw materials in production, they still need to be standardized, easy to clean, intelligent and environmentally friendly, and compact. As the current food packaging equipment needs to achieve more functions in a limited space, the size requirements for pneumatic components are becoming stricter. Typical products include the British Norgren easy-to-clean valve island VM series, which is only 10 mm wide, the valve body can provide 430 L / min flow rate, and can be integrated in 20 positions, in line with the trend of IP 65 and complex control of food packaging. In addition, advanced food packaging equipment generally consists of filters, pressure reducing valves, non-oil lubrication valves and cylinders. The utility model does not add grease, can work for a long time, reduces fuel consumption and cost, improves the environment, facilitates maintenance, and has stable performance.
Intelligentization of pneumatic devices
With the continuous progress of food vacuum processing technology, the level of automation of food vacuum skin packaging is also continuously improved. At present, the research and development of food vacuum skin packaging machinery are moving towards high speed, multi-function, and intelligence. Industrial robots, microelectronics, computers, intelligence, and image sensing technologies will be used more and more widely. The application of technology in food vacuum skin packaging machinery will become more intelligent and networked.
The intelligent cylinder is an integrated intelligent cylinder. Take NORGREN intelligent cylinder as an example. The cylinder has a built-in solenoid valve and a speed control valve. The cylinder provides FIELDBUS and ASI interfaces, which can realize remote centralized control of the bus. With IP66 protection level, easy to clean. It also complies with ISO / VDMA standards and is interchangeable with common standard cylinders. This type of cylinder can replace the traditional full pneumatic circuit.
The intelligent pneumatic triptych enables self-diagnosis of the air handling system. Most of the pneumatic system failures are due to the air conditioning system. The intelligent triple trip effectively solves this problem. It can continuously monitor the pneumatic system and display related data through the fieldbus and ASI connection at any time. When the filter or lubricant needs to be replaced, the stress state is normal, and the time is recorded to achieve the lowest failure rate and reduce maintenance costs. Improve uptime and productivity.
The development and application of intelligent and networked pneumatic technology will further realize the intelligence of food vacuum skin packaging machinery, realize self-diagnosis of equipment, and improve the automation level of food packaging machinery in China.
