Extractors for Raw Fibre Determination

Extractors for Raw Fibre Determination

The analysis of raw fibre in food and feed is important and interesting for several reasons, but some of the technical issues about reliability, reproducibility, ease of use, were, up to now, only partially solved, whichever method is used (Weende, Van Soest).

Velp Extractor Model FIWE 3 and FIWE6

Considering the profusion of problems related to nutrition in general terms, Velp introduced the FIWE 3 and FIWE 6 units for raw fibre determination, intended for small and medium sample throughput, which is an appropriate answer to those issues.

Features:

• Suitable for AOAC and AACC methods
• Applications:
• Raw fibre (Weende, Wiljkstrom)
• Acid and neutral detergent fibre (Van
• Soest)
• Lignin
• Cellulose
• Hemicellulose
• Sample size: 0.5 - 3.0 g.
• Reproducibility: about +/- 1%
• 3 samples (FIWE 3) or 6 samples (FIWE 6) processed simultaneously
• Epoxy painted stainless steel structure with excellent resistance to the attack of
• chemical and mechanical agents and to corrosion in general
• Cold and hot extractions
• Air pump for sample removal
• Peristaltic pump for reagent discharge
• Timer with acoustic alarm
• Electronic variable temperature setting
• All the extraction phases operated by rotating valves
• Separated outlets for reagents and cooling water
• Signals absence of or insufficient cooling water
• Samples can be individually processed
• Dimensions:
• FIWE 3 - 530W x 390D x 620H mm.
• FIWE 6 - 750W x 390D x 620H mm.
• Power:
• FIWE 3 - 800 W
• FIWE 6 - 1200 W
• Weight:
• FIWE 3 - 35 Kg.
• FIWE 6 - 46 Kg.

F30520204: Velp Cold Extractor Model COEX, 6 places

Supplied with 6 glass crucibles.

Samples to be submitted to raw fibre determination should have a fat content lower than 1%. If the fat content is higher than 1% then a preliminary extraction of ground material using acetone, hexane or petroleum ether is performed. The COEX equipment allows a rapid defatting of samples in the same glass crucibles used with the FIWE 3 and FIWE 6 for subsequent crude fibre determination.

Features:

• Suitable for AOAC and AACC methods.
• Applications:
• Raw fibre (Weende, Wiljkstrom)
• Acid and neutral detergent
• fibre (Van Soest)
• Lignin
• Cellulose
• Hemicellulose
• Sample size: 0.5 - 3.0 g.
• Reproducibility: about +/- 1%.
• 6 samples processed simultaneously.
• Epoxy painted stainless steel structure with excellent resistance to the attack
• of chemical and mechanical agents and to corrosion in general.
• Dimensions: 750W x 380D x 280H mm.
• Equipped with very efficient rotating valves and peristaltic pump for the discharge of the reagents.
