Armfield - Miniature-Scale Research & Development Technology - FT25 Scraped Surface Heat Exchanger System

Armfield miniature-scale technology is well established as 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 physio-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 on the membrane technology control panel. The operator can choose the parameters wanted for any particular formulation.

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

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 turnaround for increased productivity. All services required are housed inside the washdown cabinet, which also contains a drawer mounted with the electrical chassis.
