Using a crude fiber analyzer, the crude fiber analyzer is an instrument that uses the commonly used acid-base digestion method to digest samples and perform weight measurements to obtain the crude fiber content of the samples.

Using accurately concentrated acids and bases, the sample is digested under specific conditions, and then ethanol is used to remove soluble substances. After high-temperature burning, the amount of minerals is deducted, and the content is called crude fiber. It is not an exact chemical entity, but a rough composition measured under the conditions of recognized mandatory provisions, mainly cellulose, with a small amount of hemicellulose and lignin.

Suitable for measuring the crude fiber content of various grains, feed, etc., and the test results comply with the provisions of national standards GB/T5515 and GB/T6434.

Crude fiber analyzer is widely used in grain, feed, and other agricultural and sideline products.
