THE FLOWCHART IN PROCESSING
OF PALM OIL
Is the station for weighing , acceptance and
shelter while TBS is sent from the garden so it is
ready to be processed further .
Consists of :
* Weighbridge
* Loading ramp

FFB boiling process using heat from the
high-pressure steam , conduction and
convection .
 Convection : steam infusion process to
eliminate the air in the room sterilizer to
fruitlet .
 Conduction : process steam to remove
the air intake on the sidelines ( fruitlet )
to kernel .


The purpose of sterilization are :
• Deactivate the enzyme
• Facilitate the release of the bunch
featherless
• Lowering water levels
• Solving emulsion
• Removing fiber and seed
• Assist in the release of the core of the
shell

STATION THRESHER
STATION THRESHER
Main operational Threshing Station
1 . Feed to the Threshing Drum
2 . Fruitlet separation of FFb
3 . Material handling has been
separated
16
Which must be considered in operational Thresher :
 Avoid Feeding
Over Oil Losses in EB , Motor
Over Load , pulp damage due to the recycle of
the Conveyor Fruit .
 The height of kickback ( for a good stew = 1.2
meters )
 Number of kickback for every ffb = 6 times
 feed capacity is reached ( not overfeeding )
PURPOSE
 Conditioning Fruitlate in Digester
 Extraction of Crude Oil in the press
machine
 leads to the Press Cake and Nut Cake
Braker Conveyor
 Keeping achievement capacity / hour
1 . Releasing oil from the
pericarp cells ( bacon
pieces)
2 . Separating pericarp
and Nut
3 .homogen
4 . Maintaining a
temperature of 90oC 95 ° C

Function for extracting crude oil from the
flesh of the fruit that has been wracked with
loss minimal and Nut cracked Minimum .
Station which is the process of achieving
the maximum efficiency of the recovery
kernel with optimal quality production
and minimal losses .
The main stages of the operation :

Phase Nut Conditioning

Solving Nut Stage

The separation between Kernel and Shell

cracked/ kernel releases from around the nut ,
so it will increase the effectiveness of the split
nut kernels and avoid losses due to broken
kernels , broken nut and nut intact .
carried in :
o Stew
o Digester
o Drying and Cooling Process on Nut Silo
Purpose : split nut with maximum efficiency by
minimizing broken kernels , broken nut and nut
intact
Purification process of crude oil
produced from the Press which
still contains some moisture ,
sludge and mud .

The processing of FFB into the Palm Oil consists of :
a. Main station
 Fruit reception
 Stew ( Sterilizer )
 Threshing
 Enumeration ( digester ) and compression ( Presser )
 Purification ( Clarifier )
 Separation of shell and kernels
b. Station support
 Generating power ( Power )
 Laboratory
 Water Treatment
 Storage
 Workshop
In the palm oil mill existing station is very
important , if there is one station that
serves the plant can not be run due to
the processing of palm oil mill steps
sustainable and rely on other major
stations.
