The FT25XA 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 required for any particular formulation, these include margarine, shortening and ice cream processes. The FT25XA has a number of configurations according to the required use. 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 FT25XA is a lab-scale crystalliser with scraped surface heat exchangers mounted on a stainless-steel frame supplied with a large 15.4 inch HD touchscreen and ArmBUS control system. The working platform can accommodate one or two barrels (B) and a variable speed pinworker (P) alongside the hopper and connection ports.
The unit is housed in a Stainless Steel (304) cabinet with removable sides for easy access. It uses a refrigeration system, supplied within the cabinet with a chilled, food-grade refrigerant, which is pumped through the barrel jackets. An air incorporation system with pump and control can also be added if required. Enhanced CIP system is also available.
Small batch sizes enable rapid product testing saving time, ingredients and utility costs.
Small batch sizes enable rapid product testing. Enhanced CIP facility available (FT52).
Note: For Scraped surface heat exchanger applications involving product heating, UHT, or combined heating and cooling, please enquire about our FT174XA – Modular Miniature HTST/UHT Process System.
Available:
Windows™ Data Capture Software
The FT25XA can data log all operational parameters when activated by the operator. The data will be stored in discreet data files which can be downloaded to a USB stick to allow for offline analysis using spreadsheets.
Supplied as standard, the FT25XA can data log.
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.
