FT74XA HTST/UHT Unit

The FT74XA is compact, mobile and easy to install. It has an integral pressurized hot water generator and requires only electricity and cooling water to operate making it ideal for confined spaces with limited services. 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 pasteurization temperatures flow rates of up to 60 L/h are achievable. Cleaning is in place (CIP) using the feed pump in high flow rate mode and there is a centrifugal pump CIP option which generates very high cleaning velocities to deal with products that are particularly difficult to clean. Sterilization (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 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 data stick for further analysis. The FT74XA service unit provides heating and cooling services, controls and instrumentation to run the Armfield miniature-scale heat exchangers as described below. The heat exchangers fit on top of the service unit and can be interchanged easily in just a few minutes. The service unit comprises a feed tank, a product pump, instrumentation for the heat exchangers and an electrically powered hot water boiler (4kw standard with 6 kW with a controllable pre-heat option) with a recirculation pump. It is controlled by an integral PC with a 15” HD Touch Screen.
