Continuous Palm Oil Extraction Plant
Hydraulic presses and the older centrifuges have been deemed almost redundant today as palm oil extraction plants these days use specifically designed screw-presses much like the ones used for other kinds of oil seeds. These are made of a rod-shaped punctured enclosure and a narrowly fitting screw running through it. The seeds are unceasingly carried through the enclosure and taken to an opening that is restricted by a conduit.This generates the pressure that is needed to eject the oil via the
perforations in the enclosure.
Oil cells that are not broken in the machine normally stay unopened when a centrifugal or hydraulic system is used. Due to the commotion and massage action that is applied on the seeds in the enclosure, screw presses are the most effective in breaking open the oil cells that remain unopened and hence extract more oil These presses can be viewed as an extra digester. They are ideal for the extraction of oil.
Batch Palm Oil Extraction PlantIn batch palm oil processing plant, the palm oil material is put in a very heavy metal enclosure and then a metal nozzle is used to apply force the material. The key dissimilarities in the various batch press designs that exist are listed below:
- The technique that is used to move the metal nozzle and apply pressure to the palm oil material
- The extent of pressure that is applied to the palm oil material in the press
- The volume and mass of the enclosure the palm oil is placed in prior to pressing
Batch and Semi-continuous Palm Oil Extraction Plant
The nozzle may be moved by hand or mechanically (using a motor). The mechanical technique is quicker but it costs more money to utilize.Diverse designs use different methods; a screw press uses a screw thread, and a hydraulic press uses a lift system to move the nozzle about. Higher forces may be achieved by using a hydraulic press. However, care ought to be taken to guarantee that the toxic hydraulic fluid does not get into contact with the raw material or with the oil. The hydraulic fluid may take in vapor from the air and lose its efficiency and the nozzles may then wear out and requisite recurrent replacement.
The screw press threads (of the screws) are made of hardened steel and are held together by less hard steel nuts to ensure the nuts tire out quicker than the screw itself. This is because nuts are less expensive and stressful to replace than screws. The mass of the confine ranges from 5 kg to 30 kg.On averages, the enclosures mass is about 15 kg. Pressure that is applied on the raw material ought to be gradually increased so as to allow the oil time to escape. Where the profundity of material is too big, the oil will be stuck in the center. To avert this inconvenience, weighty layer plates may be introduced to the raw material to be processed. The rate of production in thebatch press greatly depends on the mass of the enclosure and the time that it takes to fill up, press, and then empty each lot.
