Product Description
Mini soya oil refinery plant/china soyabean oil refinery machine
Crude cooking oils obtained by pressing or extraction are sometimes used directly for food and feed purposes. In most cases, however, the crude oils are refined. Crude oil refining entails the removal of gums or crude lecithins and that of free fatty acids (FFA) from the oil to get a neutral taste of the edible oil while maintaining the nutritional value and ensuring the quality and stability of the product.

Degumming: chemical and physical refining
Degumming is the first step of refining and involves the removal of the gums/crude lecithins from the oil.
Neutralisation: chemical refining
FFAs are responsible for oil acidity. Chemical refining is the traditional method of oil refining and involves a neutralisation step of these FFA’s in the crude oil. During neutralisation, the oil is treated with a food grade alkali solution (caustic soda) that reacts with the FFA to form soap stock.
Bleaching: chemical and physical refining
The purpose of bleaching (or decolorising) is to reduce the levels of pigments such as carotenoids and chlorophyll, but this treatment also further removes residues of phosphatides, soaps, traces of metals, oxidation products, andproteins. These trace components interfere with further processing. They reduce the quality of the final product and are removed by adsorption with activated clay or silica.
Winterisation: optionally both chemical and physical refining
During winterisation waxes are crystallised and removed in a filtering process to avoid clouding of the liquid fraction at cooler temperatures. Winterisation processes using temperature to control crystallisation are carried out on sunflower and maize oil. This process is also referred to as dewaxing.
Deodorisation: chemical refining
Deodorisation is a Mini soya oil refinery plant/china soyabean oil refinery machine steam distillation process that removes the relatively volatile components that give rise to undesirable flavours, colours and odours infats and oils.
The purpose of deodorisationis to remove odours, off-flavours and other Volatile components such as pesticides and light polycyclic aromatic hydrocarbons by stripping Careful execution of this process will also improve the stability and the colour of the oil, whilst preserving the nutritional value.
Distillation: physical refining
Physical refining removes the FFAs by distillation; the boiling point of the FFA is lower than that of the triglyceride oil. FFA from physical refining are referred to as fatty acid distillates. Stand-alone refineries, i.e those that source crude oils and hence don’t crush oilseeds often apply physical refining to tropical oils such as palm oil, palm kernel oil and coconut oil. Integrated crushing and refining plants may also apply physical refining to seed oils such as rape seed, sunflower seed and soybean oil. Physical refining does not involve a neutralisation step of the crude oil and hence no soap stock production.
Fractionation
Fractionation entails controlled crystallization. Solids are removed by means of solvents or winterization or pressing. Pressing happens with hydraulic pressure or Mini soya oil refinery plant/china soyabean oil refinery machine filtration.
Fractionation is used to produce specialty fats from palm and palm kernel oil.
