At present, there is no systematic research data on the rheological properties of edible vegetable oils at home and abroad. For liquid agricultural materials, the most important parameter is the viscosity of the liquid. The measurement of the rheological behavior of liquid agricultural materials is mainly the measurement of viscosity, and there are many instruments for measuring the rheological behavior of liquid agricultural materials. Different instruments each have a specific measurement range. When measuring the actual material, select the appropriate instrument. Therefore, it is necessary to discuss the measurement method of edible vegetable oil.

The viscometer can control the temperature through the auxiliary heating device, and the calibration is also more convenient. It only needs to measure the time of 20()nIL flowing out of the distilled water at 20C. It can be adjusted according to whether it meets the requirements of the instrument. The convenience can be measured by the capillary viscometer. The absolute viscosity of the sample. However, the relative measurement method is generally used because it is limited to the level of the manufacturing process and the convenience of operation. In this way, some errors can cancel each other to achieve the purpose of improving accuracy. When used for relative measurements, the amount of test liquid and control liquid must be the same. Can be used with a constant temperature water bath to measure the viscosity at different temperatures. In operation, the verticality must be guaranteed. Currently, it can only be measured visually. This is not very convenient for operators. Due to the small diameter of the capillary tube, cleaning is not easy and the drying time is longer. When measuring a viscosity of a few thousand cSt, the measured value can be accurate to 18,000. It is generally used for accurate analysis of low viscosity samples, but is not suitable for measuring the viscosity of highly viscous and moderately viscous liquids.
When the viscometer measures the viscosity of edible vegetable oils, the correlation between the readings is better. In industrial applications, the Engler Viscometer can easily measure the viscosity of liquids. The ball-type viscometer is suitable for measuring medium viscosity liquids. In product testing, column-type viscometer is recommended. The experimental analysis of edible vegetable oil must ensure the measurement accuracy, capillary capillary viscometer is preferred.
