Development trend of international packaging and food machinery
at present, the countries with high level of packaging and food machinery abroad mainly include the United States, Germany, Japan, Italy and the United Kingdom. German packaging machinery is in a leading position in terms of design, manufacturing and technical performance. In 2002, the output value of German packaging machinery reached 3.4 billion euros, and 77% of its output was export products. In recent years, the development of packaging and food machinery and equipment in these countries has shown a new trend
automatic process flow because the density of titanium alloy is much smaller than that of steel, the degree of automation is getting higher and higher. At present, automation technology has accounted for more than 50% of the packaging production line. Computer design and electromechanical integration control are widely used to improve productivity, improve the flexibility and flexibility of equipment, and increase manipulator to complete complex packaging actions (simulating manual packaging). Each manipulator is controlled by a separate computer. The camera monitors the packaging action and feeds back the information to the computer to adjust the action range and ensure the high quality of packaging
at the same time, it has the function of automatic identification of packaging material and thickness, and then the computer calculates and controls the mechanical action. It is completely an "adaptive" system to ensure that the system works in the optimal state. Improve production efficiency, reduce process cost, and meet production requirements to the greatest extent. At present, the beer and beverage filling equipment in Germany has reached 120000 bottles/hour, and the cigarette packaging machine has reached 12000 pieces/minute. Once the high-speed equipment fails, the loss is also amazing, so the high-speed equipment must have a fault analysis system (self diagnosis system) and be able to eliminate the fault by itself, so as to improve the productivity
to adapt to product changes, the design needs to have good flexibility and flexibility. In order to adapt to the needs of competition, the cycle of product upgrading is getting shorter and shorter. Some products even change every season, and the output is large. The life of packaging machinery is much longer than the life cycle of products. Therefore, some packaging machinery can only adapt to product changes with flexibility and flexibility and under such circumstances for a long time, including the flexibility of quantity Flexible construction and supply. The structure can be modular and the supply is flexible, which means that one machine can realize a variety of packaging combinations, with multiple feeding ports and different forms of packaging
strong supply capacity in complete sets. For example, a beverage filling line has more than 200 microcomputer components and more than 100 control software. The filling and capping part is a combination of two sets, which are shared by other parts. A supplier can carry out engineering design, installation and commissioning for users, and finally submit them to users for acceptance. Simulation design technology is widely used in packaging machinery design. Various machine units are stored in the computer in the form of database. At the same time, the drawings are digitized and input into the computer, and the computer automatically synthesizes the three-dimensional model; Then transmit the actual production indicators and data to Europe
due to public opinion reasons, the EU has established a labeling system for genetically modified food, and the regulations covering this content came into force in April 2004. ②. For fixtures with small experimental force, many other countries have also followed the practice of the European Union. However, the birth of the labeling system has also attracted attention to compliance control, resulting in the research on the sampling and analysis methods of genetically modified food. Under the proposal of Germany (the research on the detection methods of genetically modified organisms was officially started in 1997), the Technical Committee for food analysis (cen/tc275) established a working group to develop the detection standards of genetically modified organisms and food. The working group gathered representatives from the scientific community, the food industry, analytical laboratories, and food control agencies
ISO established a working group in July 2000 in accordance with the framework of the 1991 Vienna agreement. The draft standard is dominated by Cen, and has been evaluated by ISO and Cen members, and finally reviewed by the ISO working group. If voted by peers, the standard will become a cen/iso standard, mainly including: sampling method, protein method, nucleic acid extraction method, quantitative nucleic acid method, basic requirements and definitions. When the whole standard system is integrated into a production line, the ordering process will be based on the GM food detection strategy. Since cen/tc275 focuses on food, the ISO working group will focus on genetically modified seeds
at present, the draft of real-time quantitative PCR detection standard for genetically modified organisms of oilseed and oilseed (soybean) flour has been formed. Standardization of microbiological analysis with the aggravation of the harm of microbial food pollution to human body, consumers and health management departments are increasingly urgent to formulate credible and internationally coordinated microbiological detection standards as a means of government control and mutual recognition in international trade. To this end, ISO plays its coordinating role and is committed to the standardization of microbiological analysis, aiming to make the standard widely applied to environmental samples in the fields of food, animal feed, food production and food processing
iso standard is formulated on the basis of European Microbiological standard regulations (Draft), and the regulations of other countries are cited. This standard is the basis for laboratory accreditation in the field of food microbiology, and will also benefit the food industry. At present, the progress of standard formulation is as follows: iso16140 draft method for microbial alternative validation of food and animal feed products was published in 2003. Iso6579 test method for microbiological (Salmonella) level of food and animal feed products. This standard makes the most popular analysis on food microbial pathogens. At the same time, the standard includes the internal test data of American and European laboratories. At present, the ISO working group is working on the development of uncertainty measurement guidelines for microorganisms
