DW-F800 Fiber Analyzer

DW-F800 Fiber Analyzer is with advanced design, easy operation and flexible application. It can be used in the conventional Weende method to analyze crude fiber and Van Soest analysis to wash the fiber. Applies to plant, feed, food and other agricultural products as well as the determination crude fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose and acid detergent lignin (ADL).

Characteristic of DW-F800 Fiber Analyzer

Hidden solution barrel pull structure designed to facilitate dosing operation, and provide the safest fiber analysis.
Corrosive liquid is not in contact with any pump body, to avoid waste discharge pump susceptible to corrosion phenomena.
The crucible recoil function is designed to prevent sample in the crucible can not caking filtration.
With dosing overflow protection function prevents dosing corrosive liquid overflow due to operator error, protect the safety of the operator.
Adjust the crucible heating power in time, enabling customers to control the heating rate easily and low down energy consumption, ECO-friendly.
Having a built-in pre-heating function, greatly reduces the whole experiment time.
Provide five various specifications crucible specifications to meet the needs of different samples for standard configuration.
Can detect crude fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose and acid detergent lignin (ADL).
Optional peripheral accessories: cool extractor. Experiments can go fat, washed with acetone extraction after detection of acid lignin and other steps.

Precise control experiment

Test time can be set free, clockwise and countdown timing functions are available, real-time reminder end of the experiment, the experimenter to facilitate precise control experiment, save test time, and improve efficiency.

Integrated infrared heating technology

Advanced integrated infrared heating, more uniform heating of the crucible fast, more consistent sample extraction, higher extraction recovery, thereby improving the accuracy of test results.

Applications of Fiber Analyzer

Textile Industry

Used to detect the mixing ratio of natural fibers (cotton, linen, wool) and synthetic fibers (polyester, nylon).

Paper Industry

Used to analyze the type and length distribution of fibers in pulp to optimize production processes.

Food Industry

Used to detect the dietary fiber content in food to ensure the accuracy of nutrition labels.

Pharmaceutical Industry

Used for fiber performance testing of drug carrier materials.

FAQ

It mainly adopts Van Soest method, which can sequentially detect neutral detergent fiber (NDF), acid detergent fiber (ADF) and acid detergent lignin (ADL), and calculate crude fiber content. It is widely used in feed, grain, forage and food industries.

Applicable samples include grains, feeds, straw, fruits and vegetables, herbal residues, etc. Liquid samples need to be dried and made into solid powder before testing.

Main reasons: incomplete washing of sample residues, insufficient filtering, residual acid-base liquid in filter bags, incomplete drying, or sample contamination during transfer.

After each test, drain residual acid and alkali solution, clean the heating tank and filter devices. Regularly check pipelines for blockage, replace aging silicone tubes, and keep the heating cavity clean without residue accumulation.

Main consumables: filter bags, crucibles, filter cloth, silicone tubes. Filter bags are disposable for each test; silicone tubes are replaced every 6–12 months; intact crucibles can be reused repeatedly.
