coarse fiber tester

coarsefiber testeris an instrument that digs the sample according to the commonly used acid-base digesting method and measures the weight to obtain the crude fiber content of the sample.

The use of accurate concentrations of acids and alkalis, under specific conditions to digest the sample, and thenEthanolRemove soluble substances, after high temperature burning after deducting the amount of minerals, the content is called.crude fiber. It is not an exact chemical entity, but a general composition measured under the conditions of recognized mandatory regulations, in which cellulose is the main component, and a small amount of hemicellulose and lignin.

It is suitable for the determination of crude fiber content of various grains and feeds, and the test results are in line with the national standard GB/T5515 and GB/T6434.

measurement object: all kinds of grain,feed, cereals, food and other agricultural and sideline products

The system is mainly used to extract crude fiber, acidic and neutral detergent fiber, cellulose, hemicellulose, lignin, etc. in cereals, food, feed, etc., and to detect total, soluble and insoluble dietary fiber in food. Its specific characteristics are: the number of samples tested by the crude fiber analyzer is 3/time, the sample volume is 0.5-3.0g, and the reproducibility is <+/-1. the air pump back blowing technology is adopted to accelerate the experimental process. all extraction processes can be operated by automatic valve placement. each sample can be operated separately, and the experimental results meet the standards of AOAC, AACC, EPA, DIN, ISO, APHA, etc. The number of samples tested by the dietary fiber analyzer is 6 times, the sample volume is 0.5-3.0g, each sample can be processed separately, with built-in peristaltic pump, vacuum filtration, adjustable vacuum degree, gas backflushing, accelerated washing, circulating constant temperature water bath, high precision temperature control, 6-bit magnetic stirring device, electronic timing alarm. Note: The equipment is now equipped with 30 imported crucibles. During crude fiber extraction, the pretreatment of samples with fat content greater than 1% shall be additionally selected (COEX cold leaching device is not yet available).

use

crude fiber tester is based on the commonly used acid-base digestion method to digest the sample and measure the weight to obtain the crude fiber content of the sample. Crude fiber tester using accurate concentration of acid and alkali, under specific conditions, digestion and boiling samples, and then ethanol to remove soluble substances, after high temperature burning after deducting the amount of minerals, the content of crude fiber. The crude fiber analyzer is not an exact chemical entity, but only a rough composition measured under the conditions of recognized mandatory regulations, with cellulose as the main component and a small amount of hemicellulose and lignin.
