Description

The deodorising process vessel has a batch size of 25 litres and is mounted in a floor-standing stainless steel framework, which also houses the high vacuum equipment, control console, discharge pump and polishing filter.

A 3.0kW electrical heating element is incorporated in the vessel to heattheoiltotemperaturesofupto250°C.Thevesselalsocontains a special steam distribution tube, which enables the thorough steam/oil mixingrequired.

An immersed cooling water coil provides a means of reducing the oil temperature on completion of the process.

A multi-stage vacuum system incorporates a steam ejector, condenser and liquid ring vacuum pump to achieve vacuum levels less than 5mm Hg (ABS), 6.5 mbar in the process vessel. Accurate indication of the vessel pressure is achieved using an electronicpressuretransmitter,whichindicatesthevacuumlevel downtooneTorronadigitaldisplayinthecontrolpanel.
