求一篇120字的大学英语作文，关于食品安全

As the saying goes, food is the most important thing for people. Food safety is very important for people.Nowadays, there are more and more food safety problems. Many people use bad substitutes for low-cost production. It scares us.We are all very worried about buying bad things, and businesses ignore our food safety for their own interests.

翻译:俗话说的好，民以食为来天，食品源的安全对于人们来说是很重知要的。现在的食品安全问题越来越多。很多人为了低价生产而用不好的代替品。这令我们感到很害道怕。我们都很担心买到不好的东西，商家为了自己的利益而不顾我们的食品安全。
Nowadays, a lot of museums open to the public for free, However, it also brought some unexpected problems.First, museums open to the public the crowds in the museums may also cause security problems.

The only Asia's most advanced German technology, high-end alternative to Food metal detectors.
Quality assurance: Where to buy factory products have enjoyed a March year replacement and warranty and other services.
1 Food metal detectors metal detectors food biscuit cake food metal detector field of application:
1 Meat, bread, sausages, dairy metallic foreign body detection
2 food industry, plastics industry, the timber industry, packaging industry, other industries plate chain design for frozen products and seafood as well as special industry products.
(2) Food Food metal detectors metal detectors biscuit cake food metal detector features:
Metal detectors principle: the use of alternating current through the coil, resulting in a rapidly changing magnetic field. The magnetic field inside the metal object can be an eddy current can be induced. Eddy current will produce a magnetic field, the magnetic field affect the original upside down, causing the detector beeps. Accuracy and reliability depends on the stability of the metal detector frequency electromagnetic launchers, general use from 80 to 800 kHz operating frequency. The lower the frequency, the better the detection performance of iron; the higher the frequency, the better the performance of the detection of high carbon steel. Food metal detector sensitivity of the detector increases with the decrease of the detection range, the sensor signal depends on the metal particle size and conductive properties.
Good mechanical manufacturing process: stainless steel probe and rack, a variety of protection class choices for customers, adapt to a variety of production environments conveyor anti-deviation design: the use of special anti-deviation conveyor design, effectively prevent rich belt deviation The peripheral interface (optional): You can configure the RS-485 data communication, PLC programming node, printer output, can provide real-time data for the production management system for remote control, analysis and monitoring, provide valuable retrospective information
