Employs highly efficient electromagnetic heating methods –
minimising energy usage
Treating meal with non-contact microwaves and rupturing cells
to maximum oil yield
Microwave allows high internal temperatures but LOW bulk
temperatures
Providing a very flexible and controllable continuous thermal
process – electromagnetic energy is instantly responsive to the
control system – no thermal degradation of oil
Occupies a very small foot print – the central processor is
smaller than a 40 foot container
Low operating cost with less than 3 year capital payback
