For medium scale groundnut oil processing plant like 10-50TPD, we can provide groundnut pretreatment machines and groundnut oil press machine, which includes cleaning, crushing, flaking, cooking, pressing and filtration.
Machines used in medium or large scale groundnut oil processing plant
For input capacities above 30TPD, you can choose to use pressing method or consider to use pre-press and solvent extraction method. Because the residual oil rate of pressing method is about 6-8%. For large capacity groundnut oil processing plant, the oil wastes a lot. But the solvent extraction method uses N-hexane to extract oil from the groundnut cakes, which can make total oil residue lower than 1%.
Machines used in groundnut oil solvent extraction plant
Generally, our engineer will design the suitable process for you based on your requirement and your budget for the groundnut oil processing plant. And our Henan Doing Company can provide you high quality groundnut oil processing machine with reasonal price. If you need, please send your requirement to us!
Crude palm oil, also called red oil in Africa, can be cooked directly,
but there are many impurities, and with deep color, high acid value and
so on. To refine crude palm oil into edible oil, you need palm oil refinery machine and palm oil fractionation machine.
Palm
oil refinery machines are divided into three types: batch type,
semi-continuous type and full-continuous type. They suitbale for the
different capacity and different specifications.
Three types of palm oil refinery machine
Generally, the batch type uses chemical palm oil refining method, semi-continuous type uses physical-chemical combination refining method and full-continuous type uses physical refining method. Whichever method you choose, our engineers can help you design it.
Palm oil refining process flow chart
Palm oil refining process includes four sections of degumming,
deacidification, decolorization, and deodorization. The purpose of palm
oil refining is to remove the gum, deep color, odors, ffa in the oil, to
purify the palm oil to RBD palm oil.
Palm oil fractionation
machine is used to separate the solid palm oil (palm sterin) and liquid
palm oil (palm olein) by heating and cooling of the crystal. The purpose
of palm oil fractionation process
is to separate the palm olein and palm stearin under the different
temperature. Palm olein is the high quality edible oil in the
supermarket, and palm stearin is used for making cake and butter.
If you want to buy the machines for refining crude palm oil into edible oil, Henan Doing Company can provide you design, machines manufacturing, installation guide, worker training, etc services. Welcome you to contact us!
Because the crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage.
Vegetable oil refining process flow diagram
Vegetable oil refining process consists of four steps: degumming, deacidification, decolorization and deodorization. What functions do they have? Let me introduce to you in details.
Degumming: Remove the gums in crude oil by adding hot water or phosphoric acid.
Deacidification: Adding caustic lye for separation of free fatty acids from oil. This is a conventional process that can be applied to all the kinds of edible oil refining process.
Decolorization: Using white clay to absorb the pigment from crude oil.
Deodorization: Using high temperature steam to distill the bad smell out.
Do you want to build a vegetable oil refinery plant? We have 1-600tpd vegetable oil refinery plant supplied for you. Common input capacity is batch type: 1tpd, 2tpd, 3tpd, 5tpd, 10tpd, semi-continuous type: 10tpd, 15tpd, 20tpd, 30tpd, 50tpd, full-continuous type: 30tpd, 50tpd, 100tpd, 200tpd, 300tpd, 500tpd, 600tpd.
