SUMMARY

The FT141 and FT142 are multifunction batch process systems designed for the hygienic processing of up to either 10 litres or 20 litres of product, depending on the unit and option selected. Each system comprises the jacketed mixing tank, a high-speed mixer, a gentle agitator, a vacuum system, steam heating and water cooling of the jacket, water flush for the shaft seals. Direct steam heating of the vessel can be provided as an option.

The FT141 is capable of processing at 95% vacuum and up to 100°C. The FT142 extends the performance into UHT processing up to 140°C and 3 bar

Each tank is fitted with a large-diameter (51mm) manual outlet valve and a 25mm manual inlet valve complete with inlet funnel. All contact surfaces are 316 stainless steel. The vessels are equipped with a temperature sensor, a safety cut-out switch and a sight glass with a light and wiper. The clamped lid has a powered lift mechanism for easy raising. The heating/ cooling jacket can be pressurised and is fitted with a safety valve.

A high-speed mixing head with variable-speed control is provided in the bottom of the vessel, carefully positioned in relation to the outlet valve to enable easy drainage. The standard mixing wheel has a stator and a single knife on top. The stator rings are available with different hole sizes from 1 to 4mm. Other types of mixing units, such as a double-bladed knife with blind plate or fibre-cut, can be provided on request.

A slow-speed gentle agitator is fitted on the vessel lid. This is a double-arm agitator with a flexible scraper on one arm to prevent burn-on of the product to the side of the vessel. A liquid-ring vacuum pump is used when required to process below atmospheric pressure.

A combined pressure and vacuum gauge is used to display the tank pressure. The FT142 includes as standard an automatic vacuum control. Options are available for a cooler on the connection pipe to the vacuum pump and for a condensation collector with sight glass in the vacuum line. The mechanical seals on the rotating shafts are automatically flushed with water via a solenoid valve, activated together with the motors.

The FT141 has a PLC control system with touchscreen display as standard. The FT142 has a standard electronic panel made of stainless steel, which includes start/stop controls, speed controls for the motors, temperature display, heating and cooling setpoints, plus emergency stop. Once the heating set point has been reached the temperature is maintained using on/off control.
