FT25 Modulare Schabewärmetauscher-Systeme

Die Armfield-Technologie im Mini-Massstab ist gut etabliert und ermöglicht Entwicklern, durch Versuche mit kleinen Mengen genügend Informationen für das Scale-up auf grössere Anlagen zu sammeln. Die Rezepturen durchlaufen ähnliche physikalisch-chemische Veränderungen wie in Produktionsanlagen und die Echtzeit-Datenerfassung ermöglicht, dass Ergebnisse aufgezeichnet und reproduziert werden können.

Die FT25-Reihe von Miniatur-Massstab-Schabewärmetauschern verfügt über eine eingebaute Steuerung mit grafischer Darstellung über ein Bedienfeld in Membrantechnologie. Der Bediener kann die Paramater für beliebige Formulierungen wählen.

The FT25 has a number of configurations according to the use required.


• Full control of barrel speeds up to 1000rpm
• Temperature control system incorporated
• Integral membrane control panel enabling simple control and monitoring of all major variables
• Enclosed self-contained, mobile, stainless steel service cabinet for easy cleaning and wash down
• Hard chromed barrels
• Hygienic design
• Made from AISI 316 stainless steel
• In cabinet refrigeration

The FT25 Scraped Surface Heat Exchanger Series utilises the Armfield monocoque stainless steel cabinet with membrane technology control panel. The working platform can accommodate one, or two barrels (B) or a variable speed pinworker (P) alongside a product reservoir and progressive cavity feed pump.

The unit uses a refrigeration system supplied within the cabinet and utilises a chilled, recirculating brine system, which is pumped through the barrel jackets.

An air incorporation system can also be added if required.

Small batch sizes enable rapid product testing and a Clean-In-Place (CIP) facility speeds turnround for increased productivity. All services required are housed inside the wash-down cabinet, which also contains a drawer mounted with the electrical chassis.

Optional Accessories

FT25-DTA-ALITE Data Logging Accessory: 

Windows™ Data Capture Software
A unique benefit of the Armfield miniature-scale food processing range is that the measured data may be captured and stored to disk.

An Armfield FT25-DTA-ALITE data logging accessory transfers results to a computer. Feed pump flow rate, barrel/pinworker speeds, temperatures and pressures can be monitored in realtime. The data can be displayed in graphical and tabular forms and printed.

A computer with a USB port, and running Windows XP or later is required.


Water for refigeration cooling
Cooling water supply with flow rate of 3l/min@3bar and less than or equal to 20°C

(see ordering codes)
