Into the supermarket, various kinds of food on the shelves are colorful and dazzling. In terms of how to buy food, I believe everyone has their own unique standards and insights. However, if we look closely, we will find that more and more people will habitually look at the packaging information such as the production date and the best food date when purchasing food, especially for some short-term preservation periods. food. It seems that the date identification on food packaging is already a key element that people must pay attention to.
The identification information on food packaging can be divided into two categories according to the printing method: one is the direct contact method, such as code printing, code compression, and code printing. The characteristic is that the device and the object are in direct contact, and the object needs to bear certain pressure. For objects such as eggs and cakes that cannot withstand pressure and have irregular shapes, they cannot be used; the second is indirect contact, which is mainly reflected in the coding technology. Its characteristic is that the equipment does not need to touch objects, and the information is printed. On the surface of the object, the risk of the contents being damaged by pressure is avoided, and the requirements for printing of various shaped objects can also be met. At the same time, the coding technology has the characteristics of high speed, which is very suitable for the needs of modern high-speed production in the food industry.
For the application of coding technology in the food industry, and taking into account the diversity of food packaging, Beijing Saiteng provided two solutions.
Solution one: Saiteng introduced the Microdot series of small character inkjet printers to produce food packaging on the production date, batch number and other logos, the aircraft in the domestic similar products in a technologically advanced position, and took the lead through the CE certification. The Microdot series machine adopts a fully-enclosed casing design, no heat dissipation holes, and low power consumption, which can adapt to the humid, hot and dusty production environment. In addition, in order to match the high-speed operation of the product line, the maximum speed of Microdot is up to 95 meters per minute in double lines, which fully meets the needs of high-speed production lines. In order to ensure the continuity of food production and minimise the interruption of production due to the replacement of ink, Microdot does not need to stop and can instantly replace the ink bottle, which is fast and clean.
Option 2: In order to facilitate storage and circulation, most of the finished food products are packed in cardboard boxes. Therefore, marking information on the surface of carton packaging is also a problem that inkjet printer manufacturers need to solve. Beijing Saiteng introduced the United States Matthews large character inkjet printer. This machine adopts advanced electromagnetic valve technology and can print various texts and designs on the surface of the outer box. In the process of product circulation, DOD large character printers are used to print different regional codes on the outsourcing to prevent the phenomenon of stock picking. The effect is significant and easy to use. In addition, with the large character invisible anti-counterfeiting ink, you can also achieve product anti-counterfeiting capabilities. In view of the fact that some large external packaging boxes are not suitable for assembly lines, Beijing Saiteng developed a compact handheld ink jet printer based on large-sized printers. The entire machine was placed on a small cart and needed to push small ones. The trolley can be made to be "mobile" and is very convenient to use.
In recent years, people have paid more and more attention to the state of food hygiene. The government has also issued some corresponding laws and regulations to regulate the food market. With the improvement of people’s awareness of environmental protection and health awareness, not only the food itself, but also food packaging has become the focus of attention. Inkjet printers generally use common ketone-based inks. Such inks can generate gases harmful to the human body when they are volatilized. This is unfavorable for health. If the ink is printed on the surface of food, it may infiltrate directly into the interior and cause pollution. In contrast, the use of alcohol-based inks can avoid this phenomenon. The alcohol-based ink volatile substance is ethanol (ie, alcohol) which is not toxic to the human body. At present, 100% alcohol-based inks developed by Beijing Saiteng have been put on the market, and all parties have shown a good response. This shows that such inks should have broad prospects in the future food production industry.
In addition, the coding industry is also facing issues such as how to improve product stability and reduce product costs. Because the printer is a high-maintenance product, improving stability is a serious issue facing manufacturers, and it needs to be resolved through continuous technical breakthroughs. At this stage, the printer manufacturers in order to ensure the interests of customers, increase the intensity of strengthening after-sales service, establish a professional team of after-sales engineers, regular visits to the product, maintenance, in the event of a machine failure, guaranteed to arrive in the shortest possible time Maintenance will minimize customer losses.
