Fully Automatic Fatty Acid Analyzer for Grain Storage

Fatty acid value is a key indicator for evaluating the quality and freshness of grain storage. This article is based on the principle of potentiometric titration, and deeply analyzes the technical characteristics, performance advantages, and application value of the fully automatic fatty acid value analyzer in grain quality and safety control, providing professional technical reference for grain storage and processing enterprises.

The importance of fully automatic fatty acid value analyzer

Fatty acid value is an important parameter for determining the quality deterioration of grains such as rice and corn during storage. The traditional chemical titration method is cumbersome to operate, subjective in endpoint judgment, and has poor repeatability of results. The fully automatic fatty acid value analyzer automatically determines the endpoint through potential jump, achieving standardization and automation of the detection process, significantly improving the objectivity and accuracy of the detection results.

This fully automatic fatty acid value tester strictly follows national standards such as GB/T 20569 and GB/T 20570, and is specifically designed for detecting the fatty acid value of grains, providing a reliable technical means for controlling grain quality and safety.
