Main Steps of Edible Oil Refining

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 the 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 affecting oil quality and appearance. so this process is necessary for extremely cold areas.

Edible Oil Refining Equipment

1. Refining tanks: degum and neutralize the cude oil.2. Decoloring tank: bleach pigments from oil.

2. Deodorizing tank: remove the un-favored smell from decolorized oil.

3. Heat conductive oil stove: provide enough heat for the refining sections which need a high temperature of 280℃.

4. Vibrate filter: filter the clay into the bleached oil.

5. Steam generator: generate steam distillation.

The machines mentioned above are mainly made of carbon steel. We also have refining machines made of stainless steel, which is more durable and healthy. The stainless batch type oil refining machine is as follows:

Sterilization of palm fruits

Sterilization or cooking means the use of high-temperature wet-heat treatment of loose fruit. Cooking normally uses hot water; sterilization uses pressurized steam. The cooking action serves several purposes.

Large scale palm fruit sterilizer

· Heat treatment destroys oil-splitting enzymes and arrests hydrolysis and autoxidation.

· For large-scale installations, where bunches are cooked whole, the wet heat weakens the fruit stem and makes it easy to remove the fruit from bunches on shaking or tumbling in the threshing machine.

· Heat helps to solidify proteins in which the oil-bearing cells are microscopically dispersed. The protein solidification (coagulation) allows the oil-bearing cells to come together and flow more easily on application of pressure.

· Fruit cooking weakens the pulp structure, softening it and making it easier to detach the fibrous material and its contents during the digestion process. The high heat is enough to partially disrupt the oil-containing cells in the mesocarp and permits oil to be released more readily.

· The moisture introduced by the steam acts chemically to break down gums and resins. The gums and resins cause the oil to foam during frying. Some of the gums and resins are soluble in water. Others can be made soluble in water, when broken down by wet steam (hydrolysis), so that they can be removed during oil clarification. Starches present in the fruit are hydrolyzed and removed in this way.

· When high-pressure steam is used for sterilization, the heat causes the moisture in the nuts to expand. When the pressure is reduced the contraction of the nut leads to the detachment of the kernel from the shell wall, thus loosening the kernels within their shells. The detachment of the kernel from the shell wall greatly facilitates later nut cracking operations. From the foregoing, it is obvious that sterilization (cooking) is one of the most important operations in oil processing, ensuring the success of several other phases.

Palm oil pressing step

· However, during sterilization it is important to ensure evacuation of air from the sterilizer. Air not only acts as a barrier to heat transfer, but oil oxidation increases considerably at high temperatures; hence oxidation risks are high during sterilization. Over-sterilization can also lead to poor bleach ability of the resultant oil. Sterilization is also the chief factor responsible for the refining of palm oils, leading to poor bleach ability of the extracted oil and reduction of the protein value of the press cake.

Threshing machine

Threshing/Stripping

Palm fruit thresher

Threshing station uses strong vibration to make separation of palm fruit from palm bunches. Raw materials after sterilization are sent to bucket elevator through damp car, and elevated into threshing machine. Palm fruit separates from bunches, sent to next section elevator through screw conveyor. Empty bunches through conveyor and charger, are transported to certain place for further treatment.

Palm fruit threshing station can vibrate palm fruit from palm bunches efficiently. It makes further preparation for next step palm fruit oil press processing.

Threshing Machine

After sterilization, raw materials are sent to bucket elevator through damp car, elevated and emptied into threshing machine. It is a further preparation for next step palm fruit oil press. Threshing station uses strong vibration to make separation of palm fruit from palm bunches efficiently.

Threshing is the process whereby bunch is thrown on the revolving beater shaft, due to the action of beater, entire bunch is thrown up and is allowed to fall again and again on the revolving beaters. Thus palm fruits are separated and fall down through the screen which are collected by the bottom conveyor and is taken out from the outlet. The fruits are separated from bunches in a rotating drum.

Thereafter the loose fruits are conveyed to a digester through screw conveyor. While the empty fruit bunches (EFB) are incinerated and the ash, a rich source of potassium, is returned to the plantation as fertilizer; or used as boiler fuel or further treatment.

Plate filter for edible oil

plate filter structure

Edible oils are most often plant-based oils. They are used in cosmetics products, cooking oils, pharmaceutical drugs, biofuels, pesticides, and much more. While various oils are made for various reasons, the process to refine, purify, and filter oils can be similar.

Typically, oil is extracted from plant material by using a screw press or expeller. This oil is impure and has many free floating particles in it. In order to remove these impurities, the oil is ran through an plate filter. The plate filter will separate the impurities from the oil.

plate filter

While oil impurities can be captured with the filter cloths alone, filter aid is often used as a precoat. The precoat is ran through the plate filter first to help capture smaller impurities out of the oil. The filter aid will also preserve the life of the filter cloths and help create sluge or cake during the process. Depending on the kind of oil, other purification such as dewaxing, bleaching, deorderizing maybe required.

Henan Glory new Plate Filter specifically designed for the oil you need purified. The oil filter press is any easy to operate, safe and inexpensive piece of equipment to help filter impurities out of edible oils. An plate filter can be built to food grade specifications.

Palm fruit threshing machine

The palm fruit receive the palm oil mill as fruit bunch which is embedded with many small individual fruits. In the threshing station of palm oil mill, the individual fruits will be detached from the bunch by use of FFBs thresher/stripper. Rotating drum and fixed drum are the two main threshing machine applied in palm oil milling process. The bunch waste from the palm oil milling process is incinerated and the ash, a rich source of potassium, is returned to the plantation as fertilizer.
