This article mainly introduces crude palm oil processing, hoping to answer your questions about crude palm oil processing.
Palm oil is derived from palm fruit pressing. Because of the stable yearly output of the palm plantation and high oil content of palm fruit, palm oil is one of world’s top vegetable oil with largest production, biggest sales volume and highest trade volume. Now, palm plantation is promoted heavily in Africa, which means, crude palm oil processing would have a big market.
From fresh fruit bunches to crude palm oil, following is a brief introduction of crude palm oil processing by Henan Doing Mechanical Equipment Co., Ltd . Doing supply all kinds of palm oil machines.
Crude palm oil processing
1. Raw materials reception and storage
Workers pick fresh fruit bunches (FFB) , transport them to factory with cars, get the weight by Loadometer and discharge them to material platform which is specially designed for crude palm oil processing, laying up for latter process. Open the gate of discharging platform, FFB would fall down to the conveyor automatically and be sent to sterilizing section.
2. Sterilizing section
The function of sterilizing, known as stewing in high temperature, is to avoid the deterioration of fruit. This section can avoid the increase of palm oil AV by stewing the fruit about 60min with 300kPa steam in a specialized sterilizer.
3. Threshing section
The palm fruit proportion is about 60% of the FFB. In this section, we always use rotating drum thresher to separate palm fruit from the bunches.
The purpose of crushing is to destroy palm skin, separate the palm pulp and nuts, pound palm pulp and to damage the cell structure of palm pulp by heating at the same time, which avail the latter pressing section.
In crude palm oil processing, screw oil press is common equipment we use, the outcome of which is mixture of water, oil &residue and presscake (fiber cake).
6. Crude palm oil
Separate the fiber from the mixture derived from pressing by subsidence and filtration, after continuous subsidence we can separate oil and precipitate. With another filtration and vacuum drying, the oil is just crude palm oil as we say.
