In feed production, the crude fiber content is an important indicator for evaluating the quality of feed. It mainly refers to those parts of animal feed that are difficult to digest, such as dilute acid and dilute alkali, which are not easily digested by livestock (especially ruminants). The main ingredients are cellulose and lignin. Most people think that crude fiber will affect the animal's digestion and nutrient absorption, so it is necessary to strictly control the crude fiber content in the feed, but in fact, a certain amount of crude fiber in the feed has a certain positive effect on animal growth, and is different. The crude fiber of performance and source has different effects on animals. Therefore, from the perspective of producing high-quality feed, in order to better detect and control the crude fiber content in the feed, more and more enterprises are beginning to use fiber analyzers to determine the crude fiber content in raw materials or feed.
The fiber analyzer is also called the crude fiber analyzer. It is a professional instrument for detecting the crude fiber content in raw grain and feed. It adopts the principle of acid-base digestion, that is, sugar, starch and pectin in the sample under the action of sulfuric acid. After the hydrolysis and removal of the hemicellulose and the hemicellulose are carried out with alkali, the protein and the fatty acid are removed, and the remaining residue is a crude fiber containing impurities which are insoluble in acid and alkali, and can be removed by ashing. This is the detailed measurement principle of the fiber analyzer to determine the crude fiber content of the sample.
The traditional measurement method may require the operator to be exposed to the acid and alkali, and the corresponding operation step by step step by step is not only cumbersome, but also requires high requirements for the operator, and now the operation process is simplified by means of the fiber analyzer. The requirements for inspection are also significantly reduced, and the use of instruments to determine, the safety is higher, more in line with the requirements and objectives of safety testing. Therefore, with the improvement of the quality requirements of feed and other products, the application of professional testing instruments such as fiber measuring instruments has become more and more extensive, and has become an important force to promote the prosperity and development of the industry.
