Hot selling cooking oil refining machine/crude edible oil refinery machine

After oil pressing process or oil extraction process, we get crude oil. But the crude oil can’t flow to supermarket. The crude oil must need processing with cooking oil refining machine, especially soybean, cottonseed, rapeseed, palm kernel, etc. Then how much do you know about Cooking Oil Refining Plant? Do you have learned about refining process?

Cooking oil refining machine/cooking oil refinery plant

Refining is an essential process for a complete oil pressing line because there are still some impurities such as phospholipids, FFA, pigment, odor,etc. in the crude oil.
Cooking oil refining machine
Cooking Oil Refining machine equipment:
1. Decoloring tank: bleach pigments from oil.
2. Deodorizing tank: remove the un-favored smell from decolorized oil.
3. Oil furnace: provide enough heat for the refining sections which need high temperature of 280℃.
4. Vacuum pump: provide high pressure for bleaching, deodorization which can reach 755mmHg or more.
5. Air compressor: dry the bleached clay after bleaching.
6. Filter press: filter the clay into the bleached oil.
7. Steam generator: generate steam distillation.


Five Main Steps of Cooking Oil Refining Process:
1. Crude Oil Degumming: In this step gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization: In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization: Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
5. Dewaxing (necessary for cold areas)
Some kinds of oil like sunflower, maize germ or corn oil have waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.
As a prominent edible oil mill machinery manufacturer who is devoted to processing pure edible oil for worldwide customers, we can provide professional technical support and manufacture first rate oil machines for your edible oil refining. We can provide turnkey oil refining solution with capacities from 1-20T/D. Our cooking oil refining machine is used to process various kinds of oilseeds such as peanuts, sunflower, soybean, rapeseed, etc. And our cooking oil refining plant capacity can be customized. The complete oil refining machine can work independently or together with whole oil production line.

Soybean oil extraction machine/5tph cooking oil extraction project

Henan Doing soybean oil extraction machine adopts the most scientific oil extracting method to extract crude soybean oil from soybean meal. The advanced designed production of soybean oil extraction technology provides the high capacity soybean edible oil extraction with low solvent addition.

Soybean oil extraction project

General Introduction of soybean oil extraction plant:

New type soybean oil extraction technology utilizes solvent to extract oil out of soybean embryos through effects of wet penetration, diffusion and convert diffusion. The solvent capable of dissolving the fat separates soybean oil from the mixture of oil and solvent, and obtains crude soybean oil after solvent recycled. The solvent among soybean meal is also recycled so as to obtain extracted soybean meal.

Featured characteristics of soybean oil extraction technology:

● Scientific soybean oil extraction design with lowest solvent addition.Henan Doing adopts vacuum evaporation, and solvent soaking or spaying method to extract soybean crude oil from soybean with high oil yield and low residual oil in soybean meal.

● Environmental protective exhausted gas absorption system. There are complete sets of exhausted gas absorption system equipped with all process flow of oil extraction. This soybean oil extraction project is featured by low pollution, low energy consumption, low failure rate and stable operation.

● Rice experience with turnkey soybean oil extraction.Henan Doing owns rice experience of design, manufacturing and installation of soybean oil extraction plant with guaranteed high efficiency, high profit and reliable extraction process.

Rapeseed oil press mahcine /rapeseed oil extraction machine

Rapeseed oil press machine

Rapeseed oil is also named canola oil. Rapeseed Oil is a totally natural product. We extract the oil using a mechanical Oil Press Machine without the using of chemicals to ensure the natural goodness of the oil is preserved. As rapeseed oil has half the saturated FAT and 10 times the Omega 3 level of Olive Oil, many top cardiologists now recommend Rapeseed Oil as part of a low cholesterol diet. In addition it is suitable for high temperature cooking as it has a much higher smoke point than extra virgin olive oil.

How does the rapeseed oil press machine(canola oil press) work?
Step 1: Roll the seeds with a sheller to rupture cells and make the seeds easier to be extracted.
Step 2: Heat the rapessed slightly and feed them to the oil press machine for the first process which removes some of the oil and compresses the seeds into canola meal.
Step 3: Canola meal undergoes further processing to remove the remaining oil content. The oil content in the rapeseed ranges from 37.5% to 46.3%. So this step can’t be neglected.
Step 4: Combine the oil extracted during each step , and then subject them to processing according to the end product requirements. Different treatments are used to process salad oils, margarines, and shortenings.

Features of the Rapeseed Oil Press Machine designed by our factory:
★ Easier to operate, easier to install and commissioning.
★ Need small investment, fewer land space, but with the complete function of the production.
★ Need fewer labor than the single machines, only 2~3 persons can run the whole line
★ The semi-continuous can avoid the unstable material feeding caused by manual and can make the worker safety more under the higher temperature working situation.

Edible oil refining machine/crude edible oil refinery process

Edible oil refining machine

What is Edible Oil Refining? And why crude oil should be refined with Oil Refining Equipment?
Crude oil Extracted from oil pressing machine or solvent extraction plant inevitably contains impurities. To make the standard edible oil, the impurities must be taken out; such a process is called “Refining” Oil refinery refers to a series of refining processes that can remove FFA, gums, waxes, phospholipids and free fatty acid (F. F.A.), pigment, off-flavor and other impurities in the oil. Edible oil refinery is necessary for vegetable oils & fats or animal oils & fats so they can be used for cooking and frying foods.

What's Edible Oil Refining Process?
Edible Oil Refining Process
★ Degumming: Remove gums in the crude oil to improve oil edibility, storage and do well to downstream neutralizing section.
★ Neutralizing: Remove Free-Fatty Acids (FFAs) with caustic soda (NaOH). Soap stock is generate in this process.
★ Decolorizing /Bleaching: Remove color pigments contained in oils.
★ Deodorizing: Remove disagreeable flavor and odors that are naturally present or created during processing under high temperature.
★ Dewaxing (Optional): Oils like sunflower oil or maize germ oil (corn oil) have waxes present in them. At low temperatures these waxes give a hazy appearance to the oil. So in extremely cold areas, dewaxing should take into accout when processing these oil seeds.


Edible Oil Refining Equipment designed by our factory has the follow features:
★ Wide application for oil bearing seeds.
★ Less investment but with full refining function.
★ Change different oils easily.
★ Easy to install and operate.
★ Light weight and movable.

Main Machines in Small Oil Refinery Line
Heat Conduction Furnace: 1 set Offer enough thermo for the refining sections.
Steam Generator: 1 set Produce steam for the workshop
Refining Pot: 2 sets Remove the gum, phosphoric acid etc,
Decolorizing Pot: 1 set Remove the color from neutralized oil
Deodorizing Pot: 1 set Remove the solvent, smell, water from decolorized oil
Other Auxiliary Equipments: Hot water Tank, Bleaching earth Tank, Air compressor, pumps, filters, Valves, Electricity Control Cabinet, etc.
