An automatic titration device for measuring fatty acid value

Abstract

The invention discloses an automatic titration device. The automatic titration device comprises a stander and a titration component, wherein the stander comprises a first guide rail and a second guide rail which are horizontally arranged in a staggered manner; a first slide block is further arranged on the first guide rail and can move along the direction of the first guide rail, and a third slide block capable of vertically moving up and down is further arranged on the third slide block; a second slide block is further arranged on the second guide rail and can move along the direction of the second guide rail, and a sample container and a detection container are arranged on the top of the slide block; the titration component comprises a light box and a titration pipe, the light box is arranged at the upper part of the second guide rail, the titration pipe is arranged at the top in the light box, the other end of the titration pipe is communicated with the a titration liquid bottle, and a stirring machine for stirring is arranged at the bottom of the light box; and a titration pump is further arranged between the titration pipe and the titration liquid bottle. The automatic titration device has the beneficial effects that tedious manual operation steps are omitted, and the subjectivity for manually determining the color of a titration end point by naked eyes is avoided, so that the food detection efficiency, accuracy and impartiality are improved.

Description

technical field [0001] The invention relates to the field of grain inspection and testing machinery, in particular to an automatic titration device for measuring fatty acid values. Background technique [0002] The issue of food security has always been a topic of concern to countries all over the world. It is related to the security and stability of a country, and food testing is an important link in food storage. [0003] Fatty acid value is an important indicator of grain storage quality. At present, fatty acid value is mainly measured manually. The results of the same sample measured by different people or different laboratories have large fluctuations, low repeatability, and poor comparability. Judgment of grain quality It brings difficulties, and the pre-treatment is also done manually, the steps are cumbersome, the inspection time is long, and the national standard for the accuracy of quantitative pipetting is high. At present, there is no fully automatic fatty acid ...

[0003] Fatty acid value is an important indicator of grain storage quality. At present, fatty acid value is mainly measured manually. The results of the same sample measured by different people or different laboratories have large fluctuations, low repeatability, and poor comparability. Judgment of grain quality It brings difficulties, and the pre-treatment is also done manually, the steps are cumbersome, the inspection time is long, and the national standard requirements for the accuracy of quantitative pipetting are high

At present, there is no fully automatic fatty acid value titration instrument and equipment on the market, especially in the grain testing industry, that can replace manual titration and pre-treatment automation.
