Description
Technical field
The present invention relates to a kind of fiber digestion apparatus, this fiber digestion apparatus can be used for measuring robust fibre in mass energy plant, herbage and the feed, neutral detergent fiber (NDF) and acid detergent fiber (ADF) content.
Background technology
Cellulose and hemicellulose all are profuse natural organic high-molecular compounds in the world, are the principal ingredients that consists of plant cell wall, and they are not only plantage, also are the abundantest born of the same parents' external structure polysaccharide of all biomolecule (plant or animal).Cellulose and hemicellulose are not only in the future important clean energy resource, the especially important source material of paper industry, textile industry and fiber chemical industry.Therefore, measuring accurately and rapidly of cellulose and hemicellulose level is an important job.
The Accurate Determining of cellulose and hemicellulose level is to finish by the Accurate Determining of NDF and ADF.Neutral detergent fiber (NDF) comprises cellulose, hemicellulose, lignin, silicate and the protein of seldom measuring, and acid detergent fiber (ADF) comprises cellulose, lignin and silicate.Studies show that, neutral detergent fiber (NDF) and acid detergent fiber (ADF) are the important indicators of estimating herbage and roughage nutritive value, also are one of important indicators of estimating the biomass energy pretreating effect.Traditional NDF and ADF assay method are more, and such as near-infrared diffuse reflectance spectrometry (NIRS), Van Soset analytic approach, FOSS fibre analysis method, CAU filter bag method and ANKOM filter bag method, every kind of method all exists relative merits separately.Near-infrared diffuse reflectance spectrometry (NIRS) can be quick, measure in batches fiber substance, but its uniformity coefficient to sample is had relatively high expectations, need high, normal, basic different content sample all to have to guarantee the accuracy and stability of model during modeling, if and will keep the accuracy of model, stability, maintenance to model is a long-term and lasting job, if the model prediction ability descends in the process of practical application, also need add new representational sample and carry out the modeling rectification, NIRS also is subject to the impact of several factors as a kind of indirect analysis technology, for example collect the uniformity coefficient of spectrum chamber sample, the chemical analysis precision of sample, the representativeness of sample and environmental change etc. are so be difficult to obtain wide popularization and application.Traditional Fan Shi (Van Soset) analytic approach and FOSS fibre analysis method all adopt glass pot as the hot water nutsch filter, although FOSS fibre analysis instrument is automanual device, but exist common drawback with the Fan Shi method, owing to containing more resin in the sample, protein, the materials such as polysaccharide, these tiny particles easily form tight zone on glass core filter plate surface in the process that suction filtration separates, perhaps directly block the filter plate pore, hinder filter process, obviously prolong filtration time, even be difficult to filter, cause measuring unsuccessfully, and the cost of FOSS fibre analysis instrument is higher, Fan Shi method experimental procedure is trifling, be difficult to be promoted in the laboratory, the two also has a common shortcoming namely to be difficult to finish the quick of a large amount of samples, measure accurately, the treatable sample number of the each institute of above two kinds of methods is few, mensuration for a large amount of sample fiber content is difficult to possible, can process NDF or the ADF sample number is 6 such as every batch in Fan Shi analytic approach and FOSS fibre analysis instrument, but whole process, immersion from crucible, constant weight is to the constant weight process of sample and crucible, need 1 time-of-week, if 600 sample METHOD FOR CONTINUOUS DETERMINATION are arranged also with consuming time more than 2 years, so this is that a workload is very big, extremely long work consuming time.Therefore, obviously unworkable with above-mentioned two kinds of methods for the mensuration of the NDF of a large amount of samples and ADF.By the CAU fiber filter bag of China Agricultural University's beef cattle research centre development and ANKOM F57 filter bag and the support equipment of U.S. ANKOM company, possess measurement result accurately, the determination efficiency high, the parent who is subject to numerous laboratories and researcher comes, but support equipment price required in the mensuration process of these two kinds of methods is high, is difficult to popularize in the general laboratory of condition.
Therefore provide that one easy, easy to operate, the laboratory room small-sized fiber digestion apparatus becomes current urgent task cheaply.
