Description

Technical Field

[0001] The utility model relates to the technical field of emulsion detection equipment, in particular to an emulsion stability detection device. Background Art

[0002] Emulsion products are widely used in food, cosmetics, agrochemicals, medicine, petroleum and other fields. The stability of emulsion products is a key factor affecting their product performance and service life. Therefore, emulsion products generally need to undergo stability testing before leaving the factory. Currently, there are various emulsion stability testing instruments circulating on the market. However, the detection accuracy of most emulsion stability testing instruments is poor and they cannot fully characterize the physical and chemical mechanisms of stability changes in emulsion products.

[0003] A Chinese patent discloses an emulsion stability detection device (authorization publication number CN212301333U). In this patented technology, a Raman light generator transmits laser light to an optical probe. The laser light is emitted into the emulsion in a light-transmitting container through the optical probe to form scattered light. The scattered light is then transmitted by the optical probe to the Raman light generator to form a Raman spectrum. This completes the stability detection of the emulsion at that position in the light-transmitting container. Subsequently, the controller continues to control the operation of the driving mechanism, which drives the optical probe to move to another height position of the light-transmitting container. The above detection operation is repeated to achieve stability detection of different positions of the emulsion in the light-transmitting container. The optical probe of the Raman detection mechanism is driven by the driving mechanism to make reciprocating motion up and down, so that the optical probe can detect different positions of the emulsion in the light-transmitting container, thereby obtaining multiple Raman spectra. By analyzing the above Raman spectra, the tester can obtain physical mechanism information of the emulsion, such as the floating rate of the light phase and the sedimentation rate of the heavy phase, and can also perform qualitative and quantitative analysis of the chemical composition of different positions of the emulsion, thereby accurately and comprehensively evaluating the stability of the emulsion.

[0004] However, it has certain disadvantages: emulsion stability testing usually has high requirements on environmental conditions, especially the cleanliness of the light-transmitting container and the testing area. When opening the light shield and placing the light-transmitting container, external dust and impurities can easily enter the interior of the shell, and before the light-transmitting container is placed in the shell, dust is likely to have accumulated on its surface. These dust and impurities will scatter or absorb part of the light, resulting in inaccurate light signals received by the optical probe, thereby affecting the accuracy of the emulsion stability test results.
