Armfield - Model FT25X - Scraped Surface Heat Exchanger
The FT25X 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/icecream/crystalisation processes. The FT25X 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 FT25X Scraped Surface Heat Exchanger Series based on the the Armfield Food rated stainless steel frame with improved HMI touch screen. 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 and CIP kit can also be added if required.
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 FT174X – Modular Miniature HTST/UHT Process System.
