Abstract
A process for extracting palm oil includes an ultrasonic horn press and a megasonic clarifier. The ultrasonic horn press uses ultrasonic vibrations to rupture the palm fruit. After pressing and filtering the palm oil from the ultrasonic horn press, the megasonic clarifier applies megasonic vibrations to clarify the palm oil. The ultrasonic horn press and megasonic clarifier significantly reduce the use of water and minimizes pollution as compared to conventional processes.
Claims12
A process for extracting palm oil, comprising:
- providing palm fruit to an ultrasonic horn press, wherein the ultrasonic horn press includes an ultrasonic horn;
- in the ultrasonic horn press, vibrating and pressing the ultrasonic horn in contact with the palm fruit to rupture the palm fruit;
- pressing and filtering the palm fruit processed in the ultrasonic horn press to provide pressed and filtered palm oil;
- and
- supplying the pressed and filtered palm oil to a megasonic clarifier and applying megasonic vibrations to the palm oil to produce a clarified crude palm oil.
A process for extracting palm oil, comprising:
- heating palm fruit in water at a temperature in the range of 70° C. to 85° C.;
- providing heated palm fruit to an ultrasonic horn press, wherein the ultrasonic horn press includes an ultrasonic horn;
- in the ultrasonic horn press, vibrating and pressing the ultrasonic horn in contact with the palm fruit to rupture the palm fruit;
- pressing and filtering the palm fruit processed in the ultrasonic horn press to provide pressed and filtered palm oil;
- heating the pressed and filtered palm oil to a temperature in the range of 65° C. to 75° C.;
- supplying the heated pressed and filtered palm oil to a first tank and using megasonic transducers to apply megasonic vibrations to partially clarify the palm oil in the first tank, and then supplying the partially clarified palm oil to a second tank and using megasonic transducers to apply megasonic vibrations to further clarify the palm oil in the second tank.
