Health and environmental protection is the wish of the modern people. More attention is paid to the safety of food products. During the processing of grain into powdered food, impurities such as magnetic metals are mixed into the food because of unclean raw materials or mechanical wear. If these tiny metal impurities are ingested by humans, it will cause harm and affect the health of the human body. The national standard has strict restrictions on this (the allowable amount is less than 0.003g/kg); the level of magnetic metal content is also one of the important indicators for evaluating powder production and processing technology. The magnetic metal detector is currently the most used instrument. The advantages of the instrument are very obvious.
Because there is a certain problem in the method of determining powder magnetic metal materials, carbon tetrachloride as a rinse solution poisons the human body and pollutes the environment, and the test process takes a long time, labor intensity, and high cost; some magnetic metal detectors The result is not stable; the result of horseshoe magnet detection is low and the error is large; the unit of measurement in the method and the national quality standard mean that the unit is not uniform. The application of magnetic metal detector can be a good way to avoid this kind of problem.
The use of magnetic metal detector is accurate and reliable, and the operation is simple and fast. It not only saves time, but also reduces inspection cost and labor intensity. In particular, the toxic effects of carbon tetrachloride on the human body and the pollution to the environment are avoided. Therefore, we propose to amend the method standard to use magnetic metal material analyzer separation plate separation method instead of carbon tetrachloride rinsing method to meet human health and green environmental protection desire. The method of indicating the results of determination of magnetic metals in powdered foodstuffs. It is recommended that the number of milligrams (mg/kg) of magnetic metal contained in each kilogram of powdered grain as stipulated in the current standard be revised to the number of grams (g/kg) of magnetic metal per kilogram of powdered grain.

Oil contaminated Waste processing Plant is one of the most effecient project to process with all kinds of wastes without any second-pollution problems: we could get energy from it if there are oils or Hydrocarbon included; or there are some recycling gas as fuel for this system if there are still gases after cooled down; the rest will be mostly carbon blacks which could be sold to be further refined into N330 or N660 etc.
