Falsified food production date? RFH ultraviolet laser will never agree

As 2020 is about to enter, the goal of a comprehensive well-off society is close to being achieved, but there are still many issues that have not yet been resolved, such as food safety issues. Next, let's take a look with the RFH laser.

Spicy strips, a snack that is popular all over the country, sales reached RMB 60 billion in 2018. The market is huge, but the problem is also prominent: from 2015 to 2017, in just three years, a total of 195 batches of spicy noodles of 131 brands across the country were judged as substandard products by the food and drug regulatory authorities. In 2019, the CCTV 3.15 evening party also exposed the sanitary chaos of spicy strips in some areas. Recently, relevant departments issued new regulations, clarifying that spicy strip production companies should use food additives in accordance with relevant regulations, and the name of the food should reflect the true nature of the food. After the introduction of the new regulations, spicy strips will not be harmful to health. However, in addition to relevant regulations and supervision, technology is also needed to maintain food safety.

Falsification of production dates is a major chaos in the food industry. The production date can be tampered with because the marking method is ink-jet coding, which is easy to be erased, and bad merchants can use it to modify and refurbish. The "defects" of the process here have not been repaired for a long time in the past until the emergence of the laser marking process.

The emergence of laser marking machines has made the marked information more anti-counterfeit and traceable. The marked information can no longer be altered, which can better protect the interests of consumers and also protect the brands of enterprises, especially large-brand enterprises. Image, and the laser marking speed is fast, can cooperate with the assembly line, carry on the continuous processing of large quantities, meet the increasing demand of enterprise business. Of course, the premise is a high-quality laser marking machine that can operate stably for a long time.

To achieve the above effects, first of all, we must have a high-quality UV laser. However, there are so many UV laser manufacturers, and the products are mixed. How to choose? You can choose from the following three aspects.

1. Manufacturing experience of UV laser manufacturers

High-quality lasers must come from companies with technical content, and the technical content can be verified by the development history of the company. For example, RFH lasers have been deeply involved in the manufacture of nanosecond lasers for 12 years. We have established a top-level laser R&D team composed of Tsinghua professors and PhDs, and set up an application process R&D department, a laser R&D department, and an electrical R&D department to focus on technology research and development, including independent research and development of laser dedicated power control systems to ensure a complete laser system Stable operation. The team has obtained 10 national patent certificates, 14 computer software copyright certificates, and won the "National High-tech Enterprise", "Shenzhen High-tech Enterprise", "Software Enterprise Certification Certificate" and other certificates, and was innovated by the Guangdong 3D printing industry The Alliance and Guangdong Laser Industry Association were appointed as the governing units.

Second, the quality of UV laser product parts

The core components of RFH pump and Q switch are imported brands, and the parts cooperate with domestic first-line brand suppliers. From the source of the material procurement ecological chain, to ensure the quality of each part is a guarantee for users to use RFH brand lasers.

3. UV laser production management system

In terms of production and assembly processes, RFH is very rigorous: from purchasing and pre-production quality inspection and control, to assembly, finished product testing, warehousing quality inspection, and then to pre-delivery inspection, strict control at all levels to ensure stable quality And equipment parameters are consistent with actual operating parameters. Therefore, there are high-quality laser products, such as the Nanosecond UV laser of the Expert Ⅱ 355 series, with short pulse width (<14ns@30K); perfect spot characteristics (spot ellipticity>90%); superior beam quality (M2< 1.2) Strictly guaranteed in all frequency ranges.

Due to its strength, RFH nanosecond ultraviolet lasers are widely used in the marking and processing of food, medicine and other product packaging dates and logos.
