The FT90 and FT91 are complete inline homogenisation subsystems for use with Armfield miniature-scale food-processing equipment. The FT90 is based on an APV 1000 homogeniser and the FT91 is based on a Niro Twin Panda. Both homogenisers have been specifically optimised for this application. The units include controls, comprehensive instrumentation, valves, pipework, pulsation dampers, data logging and all facilities required for operation and process integration with other Armfield equipment.
These units have been specifically developed to provide a simple and complete solution for inline homogenisation in conjunction with the Armfield FT74X/FT74XTS range of miniature-scale processing equipment. They contain the homogeniser, pulsation dampers, a stainless steel control cabinet plus the required control valves, pipework and instrumentation all mounted within a stainless steel frame.
Hand-wheel adjustment is provided for both stages of homogenisation pressure. The homogenisation pump speed is electronically controlled from the control console, and a manually adjustable divert valve is used to compensate for any inequalities between the flow rate from the FT74X/FT74XTS and the homogeniser, or any fluctuations in these flows.
The homogenising valves, and the seats and balls of the pump valves, are manufactured from a hard wearing ceramic material, stellite. The pulsation dampers are located upstream and downstream of the homogeniser to provide smooth flow on both sides. The pulsation dampers are non-pressurised and can be easily dismantled for cleaning.
The stainless steel control console includes displays for the homogenisation pressure (both stages on FT90), for product temperature and for product process pressure. The outputs from all the sensors, together with the pump speed, are also made available on an integral USB interface. The software provided with the FT90 and FT91 enables this data to be fully integrated with that from an FT74X/FT74XTS datalogger, with a single display screen, single data table, and options to graphically display any or all of the data from either system.
