Comparison between the time of fat smoke detector and visual inspection
To measure the quality of fats and oils, smoke point is one of the important indicators, so major oil companies and testing organizations will be equipped with oil smoke point instrument to carry out the detection of grease smoke points. The reason why companies or related testing organizations choose oil smoke point meter to measure rather than select the visual method to measure fat smoke point is not only because of the new standard of GB/T 20795-2006 "Determination of Smoke Point of Vegetable Oil" in 2007. The instrument method was used to locate the first method, and the visual method was used to locate the second method. The use of a cigarette smoke point instrument was more in line with the relevant standards and requirements. More importantly, compared with the visual method, a grease smoke point meter was used to measure fat and oil smoke. The point is not only more accurate, but also requires less time, solving the problems that have long puzzled oil companies and quality inspection agencies.
In the actual measurement process, through the comparison of the time measured by the oil smoke point instrument and the visual method, we can find that the time taken to determine the smoke point index using the oil smoke point instrument method is far less than the visual method, such as In the measurement process, although the actual time required for visual measurement is less than 40 minutes, the operator needs to test the gap of each sample to ensure that the data is true and reliable. It took only 2 hours to measure the sample on the top and 2 hours for the use of the grease smoke point meter, but it took nearly 4 hours to use the visual rule to complete the entire measurement process, which was almost twice as long as the instrument method.
It can be seen that there are many requirements for manual measurement of oil smoke point instrument compared with the visual inspection method, not only the time used in the measurement process is shorter, it can save time for the development of other test items, and can It is no longer subject to the factors interfered by the test operator and can continuously test a number of samples over a long period of time. Therefore, from these points of view, the oil smoke point instrument is obviously due to the visual method, and it is worthy of promotion in the detection of oil quality. application.
