Abstract

The invention relates to a full-automatic fatty acid value detection system and a detection method and belongs to the technical field of fatty acid value detection for cereals, such as corn, wheat, rice and the like, and products thereof. The system includes: a titration pretreatment unit, which is used for stirring a sample; a quantitative liquid adding unit, which is disposed on one end of a work bench, a titration analytic unit which is arranged on the other end of the work bench, and a transfer device which moves the sample from the quantitative liquid adding unit to the titration analyticunit. The titration pretreatment unit is connected to the quantitative liquid adding unit through a transfer pump and a pipeline. By means of the system, the sample is subjected to steps of reagent extraction, vibrating extraction, filtration, quantitative transfer, indicator addition, and diluent addition; then the sample is fed into the titration analytic unit and is analyzed in order to finally obtain a detection result. The detection system can achieve non-manual intervention in the detection process and can complete the whole treatment process on a plurality of samples in one time. The system is high in treatment speed, allows simultaneous treatment on a plurality of samples and allows continuous sample injection and titration analysis, and has good repeatability. The system and method achieve full-automation on fatty acid value detection.

Description

technical field

[0001] The invention relates to a fully automatic fatty acid value detection system and detection method, and belongs to the technical field of fatty acid value detection of corn, wheat, rice and other grains and products Background technique

[0002] The detection of fatty acid value in grain is an important indicator to test the quality change in the process of grain storage. The current national standard detection method uses traditional manual pretreatment and human eye titration to obtain the results, especially in the titration process, due to human eyes The difference in color judgment and the judgment of the end point will have obvious errors, which will easily cause misjudgment and unnecessary disputes. At the same time, in the process of sample pretreatment and titration, the operation level of experimental analysts is very high, and it is difficult to complete this test with weak test points.

[0003] The current automatic fatty acid value titrati...
