The FT74XA is compact, mobile and easy to install. It has an integral pressurised hot water generator and requires only electricity and cooling water to operate making it ideal for confined spaces with limited services available in some laboratories.
Operation with either plate or tubular heat exchangers means a wide range of product viscosities can be handled. A progressive cavity feed pump ensures that flow rates are independent of viscosity/backpressure changes and allow a maximum operating pressure of 10 bar.
Typical processing flow rates are 10-20 L/h with holding temperatures up to 150°C. At pasteurisation temperatures flow rates of up to 60 L/h are achievable.
Cleaning is in place (CIP) utilises the feed pump in high flow rate mode and there is a centrifugal pump CIP option (FT74XA-52) which generates very high cleaning velocities to deal with products that
are particularly difficult to clean.
Sterilisation (SIP) of the system is controlled from the touchscreen. System sterilization time and temperature are defined and key temperature sensors are monitored to ensure the entire system satisfactorily completes the SIP cycle.
Automatic pre-heat control (FT74XA-46) offers an independent hot water circuit and the product pre-heat temperature is set via the touchscreen.
The system is well instrumented for both process and services with all sensors displayed on the touchscreen and recorded values can be seen graphically and saved to USB datastick for further analysis.
