MY184348A - System for digestion and pressing of oil palm fruit - Google Patents

Abstract

The present invention relates to a system for the digestion and pressing of oil palm fruit in a palm oil milling process. The system includes a digester (10) having an inlet, an outlet, and a perforated base plate (14) provided at bottom of the digester for discharging crude palm oil removed from the oil palm fruit, an automated level detecting means (12) for detecting level of contents in the digester (10) and controllably feeding a pretreated oil palm fruit into the digester, a water tank (16), a pipe (18) in fluid communication with the water tank (16) at one end and in fluid communication with the digester (10) at another end, for delivering water from the water tank (16) to the digester (10), an automated controller system (20) for controllably injecting the water from the water tank at a temperature of 80?C to 100 ?C into and at bottom side of the digester (10), a live steam injection having a valve for delivering steam to the digester (10), a bottom plate (32) proximate the perforated base plate (14) for collecting crude palm oil discharged from the digester (10) through the perforated base plate (14), a funnel (34) proximate the perforated base plate (14) for channeling the crude palm oil discharged from the digester (10) through the perforated base plate (14) to an oil gutter, a digester chute (22) proximate the bottom side of the digester for discharging the digested oil palm fruit from the digester (10) and a pressing means (24) for pressing the digested oil palm fruit discharged from the digester chute (22), wherein the perforated base plate (14) having through holes with a diameter in a range of 4 mm to 6 mm, the through holes are evenly spaced apart and arranged in a random manner.
