Determination of the optimum frequency for Elaeis guineensis Jacq. detachment

In Elaeis guineensis Jacq (oil palm) industry, fruit detachment and oil extraction of oil palm bunches are always being carried out in palm oil mill in a series of standard procedure. A lot of energy is needed and consumed throughout the procedure, especially during sterilization where a huge amount...
