8. determination is complex and has a certain danger in using hot acid and alkali solvent As to resolve the problem our company launches FIA 6 fiber analyzer which is specialized in analyzing the content of crude fiber NDF ADF ADL cellulose semi cellulose in materials and finished products of food grain and feed This instrument based on the crude fiber determination principle adopts high quality anti corrosion materials and can process six samples simultaneously Its precise design optimizes the operations such as acid and alkali hydrolysis cold and hot leaching air pump back blowing automatic emptying and electronic temperature control 1 Crude Fiber Determination Principle The sugar starch pectin and semi cellulose in the sample under the action of dilute sulfuric acid are firstly removed by the hydrolysis and then protein and fatty acid in the sample are removed by the alkali treatment and the left residue is the crude fiber And the impurities which are insoluble in acidic and alkali solutions in the fiber can be removed by ashing In view of the determination principle the crude fiber is not a specific chemical entity but a mixture Its rough ingredients determined under recognized compulsory conditions mostly are cellulose and few are semi cellulose and lignin 2 Operation Procedure FIA 6 User Manual V1 1 1 Heating 2 Filter nein 4 Filter Add alkali Add acid Add ethanol or ether
