FT90 FT91 Homogenisation Sub-Systems - issue 2
NOW WITH PULSATION DAMPERS AS STANDARD
The FT90 and FT91 are complete in-line homogenisation sub-systems
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, datalogging and all facilities required for operation
and process integration with other Armfield equipment.
FEATURES
> Complete Homogenisation Subsystems
> Configurable for upstream or downstream homogenisation
> Variable throughput
> Two Stage Homogenisation with adjustable pressure
(1000bar FT90, 600 Bar FT91)
> Twin Pistons (FT91) or Single Piston (FT90)
> Pulsation Dampers included
> Comprehensive instrumentation includes product temperature, product line pressure,
homogenisation pressure and pump speed.
> All these parameters are displayed on the control console and
available for datalogging via the integral USB datalogger
> Datalogging software seamlessly integrates the data with
the data from the
FT74
or similar.
> Adjustable divert facility for easy integration into continuous flow processes.
> Complete with interconnection hoses
> Can be sterilised and used in an Aseptic system
Benefits
> In-line homogenisation for trial quantities and miniature-scale processing
> Simple integration with existing Armfield plant
> Uses scale-down valve technology which ensures the results are representative
of production scale processing
Description
These units have been specifically developed to provide a simple and complete solution for in-line homogenisation in conjunction with the Armfield FT74 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 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 allows this data to be fully integrated with that from an FT74 datalogger, with a single display screen, single data table, and options to graphically display any or all of the data from either system.
The FT90 and FT91 are supplied with all necessary equipment, interconnecting
hoses, homogeniser tools etc. for trouble free integration and operation.

requirements
Electricity:
Mains Electricity (see order codes)
Water or Steam for lubrication (FT90 only)
Steam (sterile operation only)
Required Accessories
A PC running Windows 98 or later with an unused USB interface is
required for datalogging. (If being used with FT74-44 or equivalent, two USBs
are required).
For use with FT74-30MkIII, a homogeniser interconnection plate must be used. FT74-31 is used for upstream homogenisation (homogenisation during heating) and FT74-32 is used for downstream homogenisation (homogenisation during cooling).
