Abstract

One of the tools used in the pressing system is screw press, which is useful for separating oil from fruit flesh. In this process the fruit enters and is ground by a threaded shaft or worm screw press which carries and suppresses the fruit mass that is put into the press cage. On the other hand there is a hydraulic system in the form of cone-shaped rods at the ends which serve to narrow the entry and exit of fruit masses. This results in the fruit being pressed and pressed so that the oil comes out of the fruit flesh. Due to the large amount of palm oil losses that occur in the pressing process, it can therefore reduce the yield of Crude Palm Oil (CPO) produced. From this explanation it can be concluded that the hydraulic pressure on the screw press unit is very important to note so that the loss of palm oil can be reduced as small as possible where the hydraulic pressure set is equal to 50-60 Bar. As for the maintenance of the equipment, it is necessary to know the amount of pressure that occurs in the press cage, which is caused by the fruit pulp style and the force that occurs in the worm screw press so that a comparison between the hydraulic pressure and the pressure that occurs in the screw press is obtained.

Abstract

Bleaching Earth (BE) adalah salah satu komponen penolong dalam proses pemucatan minyak kelapa sawit (CPO). Minyak kelapa sawit (CPO) terdiri 2 komponen utama yaitu senyawa trigliserida dan senyawa non trigliserida, senyawa trigliserida terdiri dari ester dan gliserol sedangkan nontrigliserida terdiri dari beberapa komponen antara lain karotena asam lemak bebas tokoferolsterol fosfatida tembaga besi kotoran dan lain-lain. Kompenen karotena mengandung betakaroten yaitu sekitar 500 – 700 ppm dengan perincian 36 % α betakaroten dan 54 % β betakaroten. Dengan menambahkan Bleaching Earth (BE) yang mana prosesnya berlangsung di tanki bleacher(D202) maka pigmen merah akan mengurangi warna dan memucatkan betakaroten yang terkandung dalam minyak yang mana warna awal CPO = 20/20 menjadi 17/20. Pengaturan Bleaching Earth (BE) sangat berpengaruh terhadap stability dan quality minyak DBPO dengan dosing antara 0,6 % - 1,4 % dan dipengaruhi juga oleh quality minyak dengan spesifikasi analisa dobi. Penelitian dilakukan dengan menganalisa warna DBPO setelah melakukan trial dosing BE 0,6 % - 1,4 % dengan flowrate 83300 Kg/Jam. Dengan demikian didapatkan dosing BE yang sesuai dengan standar pabrik dari hasil perhitungan dengan menggunakan analisa regresi sederhana = 1,0 %.
