FT25 Scraped Surface Heat Exchanger Series
Armfield miniature-scale technology is well established at offering developers the opportunity to run small trials, which provide enough information to enable scale-up to larger plant with confidence. The formulations go through similar physico-chemical changes as they would in production plant and real time data logging permits results to be recorded and repeated. The FT25 range of miniature-scale scraped surface heat exchangers has built-in control and flexibility with a graphic representation of the process on the touch screen control panel. The operator can choose the parameters wanted for any particular formulation. The FT25 has a number of configurations according to the required use.
The FT25 Scraped Surface Heat Exchanger Series utilises the Armfield monocoque stainless steel cabinet with HIMI touch screen.
The working platform can accommodate one or two barrels (B) and a variable speed pinworker (P) alongside a progressive cavity feed pump (C). The unit housed in a Stainless Steel (304) uses a refrigeration system supplied within the cabinet and utilises a chilled, food grade refrigerant, which is pumped through the barrel jackets. An air incorporation system can also be added if required.
Small batch sizes enable rapid product testing.
Enhanced CIP facility available.

The splashproof, full colour touch sensitive screen with diagrammatic representation of the process. It shows variables such as product feed pump rate, barrel and pinworker speed, temperature and pressure, which are all under operator control. Process data is displayed in real time and can be logged to a PC running the Windows™ operating system. Note: For Scraped surface heat exchanger applications involving product heating, UHT, or combined heating and cooling, please enquire about our FT174X – Modular Miniature HTST/UHT Process System.

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.
