Because the ingredients and substances contained in edible oils and fats are different, their smoke points are also different. There are differences in different types of cooking fumes, the same degree of oil refining is different, smoke points will also be different, the same kind of fat Different methods and time of storage, smoke points are also different, so through the determination of fat smoke points can guide the processing and storage of oil, and the method of measuring the fat smoke point is mainly the oil smoke point instrument and visual method.
Dichloromethane (DCM or Methylene Chloride) is an organochloride compound with the formula CH2Cl2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is polar, and miscible with many organic solvents.
Methylene Chloride Dichloromethane's volatility and ability to dissolve a wide range of organic compounds makes it a useful Solvent Raw Material for many chemical processes.In the food industry, Metal Cleaning Methylene Chloride is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings.Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams.
The chemical compound's low boiling point allows the Pvc Resin chemical to function in a heat engine that can extract mechanical energy from small temperature Ethylene-Vinyl Acetate differences. An example of a Methylene Chloride 99% heat engine is the drinking bird. The toy works at room temperature.It is also used as the fluid in Christmas bubble lights Methylene Chloride Chemical that have a colored bubbling tube above a lamp as a source of heat and a small amount of rock salt to provide thermal mass and a nucleation site for the phase changing solvent.

The visual method is an earlier method of determination, that is, the temperature of the first indigo smoke is observed during the heating of the oil by the viewer's naked eye. Since the visual method is performed artificially, it is likely to be relatively large. Subjective biases, such as different detectors may have different understandings and sensitivities to the first indigo blue smoke, and after reading the blue smoke, reading the temperature of the thermometer again, there will be problems such as reading lags, so in fact, The result of visually measuring fat smoke point is often an error, and sometimes the error is still very large. Therefore, in order to accurately reflect the quality of the oil, a more accurate fat smoke point measurement method is needed. The emergence of the instrument just compensates for the lack of manual observation.
There are two very significant advantages of using a smoke detector with a cigarette smoke point meter. The first is that it uses machine vision to measure, which can overcome the defects in the process of visual inspection, so that the measured data is closer to the truth. The value can meet the requirements of precise measurement. The second is that the use of the grease smoke point instrument can improve the efficiency of the determination of the smoke point, and can effectively save the time for the detection of the oil quality. At the same time, it also expands the range of detection of the smoke point; Third, the structure of the oil smoke detector is simple, easy to use, the result display is also more intuitive, the price is relatively cheap, and the applicability is very wide, so in the quality supervision, import and export inspection, oil processing, oil storage and transportation, food processing, scientific research, The department of agricultural breeding, school, etc. that needs to determine the smoke point of vegetable fat can use the oil smoke point instrument to carry out the fast and accurate measurement of the fat smoke point.
