RBD Palm Oil Process

RBD palm oil process means Refined Bleached Deodorised Palm Oil (RBD Palm Oil) process.
palm oil process
In the past three decades the chemical refining process scheme has gradually been superceded by the more cost-effective and more environmentally-friendly Physical refining processing scheme. In physical refining the process of caustic refining is eliminated, and the vacuum deodorization has been replaced by a higher temperature Steam stripping and deodorization processes that enables the Free Fatty Acids and other impurities to be removed without the use of caustic soda. The term in the Physical Refining indicates that chemicals have not be used to remove the fatty acids. Although caustic soda is no longer utilized in Physical refining, the term RBD is still in use to describe the fully-refined palm oil.

The refining process consists of 3 major steps :

Degumming : To condition gums (phosphatides) and oxidative trace metals ( such as copper and iron ) with food grade phosphoric acid, citric acid, EDTA etc, for later removal with the spent earth after the bleaching stage
Bleeching : To remove pigments, oxidation products, residual trace metals and phosphatides, and soaps
Steam refining/deodorization : To remove fatty acids, pigments (e.g. carotenoids)

In order to increase the oxidative stability and improve the nutritional properties of crude palm oil it is necessary to treat the oil by a series of processes, that are collectively known as refining. The first stage of the processing is primarily to remove the gums and pro-oxidative trace metals, and is called the degumming stage. Historically, the next stage of the process involved neutralization of the Free Fatty Acids by caustic soda, to remove them in the form of soaps. This process was known as Caustic Refining (and represents the “R” in “RBD”). The next stage utilized bleaching earth to remove pigments, oxidation products, soaps and traces of gums and heavy metals. This is called the Bleaching stage, and is represented by the “B” in “RBD”.

The final stage being a high-temperature vacuum deodorization mainly to remove residual pigments, and oxidation products etc, which would otherwise adversely affect the flavour, odour and rate at which the oil would turn rancid. T he Deodorization stage represents the “D” in “RBD”. The fully refined oil was then termed Refined, Bleached and Deodorized Oil, or more commonly as RBD palm oil.

Our KMEC oil mill plant is suitable for crushing all sorts of oil seeds such Groundnut, Rapeseed, Cottonseed, Castor seed,  Mustard seed, Soyabean, Sesame seed, Sunflower seed, Copra, Linseed, Palm kernel etc.

Oil mill plants make use of oil pressing technology for the extraction of oil. Oil expellers play a key role to obtain premium quality oil. The oil seed pressing is done in various ways such as pre-pressing, full pressing, hot pressing and hot pressing.

Full Pressing- Oil Mill Plant
The full or single pressing technology is used for the small and medium capacity oil mill plants in which the oil seeds are pressed in one single step. Here the mills work on the principle of mechanical extraction to separate oil from seeds. A maximum yield is obtained from high oil content seeds. The discharged cake has the least oil left behind. The oil residue in the cake is around 4-6% only. Full pressing technology is used for all different oil seeds. In Tinytech full pressing oil mill plant the yield of oil is much higher and of a much better quality.

Pre Pressing- Oil Mill Plant
In pre-pressing technology, the oil seeds are lightly pressed without the application of full pressure. The residual oil content in the pre-pressed cake is about 13%-17%. The pre-pressed cake is then sent to the solvent extraction plant.  We offer pre-pressing machines for the oil mill plant that are fabricated in accordance with global standards. These machines have ease of operation, easy maintenance and low investment.

How can one Make use of Palm Oil Mill Effluent (POME)?

palmPalm Oil Mill Effluent (POME) means highly polluting waste-water which is usually discarded in disposal ponds, leading to the leaching of contaminants that pollute the groundwater and soil, and in the discharge of methane gas into the atmosphere, is from Palm Oil processing. POME is an oily wastewater generated by palm oil processing mills and contains various suspended components. This liquid waste mixed with the wastes from steriliser condensate and cooling water is called palm oil mill effluent (POME). On average, a standard palm oil mill generate about 1 tonne of liquid waste with biochemical oxygen demand (BOD) 27 kg, chemical oxygen demand (COD) 62 kg, suspended solids (SS) 35 kg and oil and grease 6 kg for each and every ton of FFB (fresh fruit bunches) processed.

You can find very high Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD), which is 100 times over the municipal sewage in POME. As no chemical is added during the oil extraction process POME is a non-toxic waste, but because of organic and nutrient contents, it will pose environmental issues due to large oxygen depleting capability in aquatic system. The high organic matter is due to the presence of different sugars for example arabinose, xylose, glucose, galactose and manose. The oil-bearing cellulosic materials from the fruits are the main suspended solids in the POME. Since the POME is non-toxic as no chemical is added in the oil extraction process, it is a good source of nutrients for microorganisms.
palm oil plant
At this point, it is a new approach in managing POME to recover the renewable organic-based product. The technology is aimed to recover by-products for example volatile fatty acid, biogas and poly-hydroxyalkanoates to promote sustainability of the palm oil industry. Furthermore, it is envisaged that POME could be sustainably reused as a fermentation substrate in production of numerous metabolites through biotechnological advances. In addition, POME involves high organic acids and is suitable to be used as a carbon source.
