Rice Bran Oil Refining Machine
1) Firstly, to pump crude rice bran oil into oil refining tank with heat conduction oil, and the temperature will reach about 70°C-80°C in one hour, then add acid or alkali to separate rice bran oil according to the acid value. After one hour’s processing and 4-6 hours deposit, then to convey soap stock to storage tank;
The steps that occur in a typical rice bran oil refining process, along with the by-products generated are given in Fig. 14.1. Generally, the first step in the refining process with crude rice bran oil is dewaxing or winterizing, although for other vegetable oils the dewaxing step can be done at different times in the refining process.

Deacidification is the process of removing free fatty acids from crude rice bran oil. The deacidification methods of rice bran oil include alkali refining, distillation, mixing, re-esterification, and extraction. The alkali refining method has comprehensive effects such as deacidification and decolorization, but the refining loss is much higher.
Degumming. Rice Bran oil contain phosphatides like other oils 1.5% max. This will be removed through the standard degumming process by addition 2% water and 1kg to 1.5Kg of food grade phosphoric acid to the oil at 60°C and allowing to mix for 20 minutes and then by separating through the centrifugal separators.
Effects of Crude Rice Bran Oil Components on Alkali-Refining
The effects of minor components in crude rice bran oil (RBO) including free fatty acids (FFA), rice bran wax (RBW), γ-oryzanol, and long-chain fatty alcohols (LCFA), on alkali refining losses were determined. Refined palm oil (PO), soybean oil (SBO) and sunflower oil (SFO) were used as oil models to which minor component present in RBO were added. Refining losses of all model oils were
Crude rice bran oil (RBO) is rich in valuable minor components such as tocotrienols, phytosterols and γ-oryzanol. These compounds are well preserved during physical refining, but in current industrial practice, RBO is mostly refined chemically because this results in a lighter color. However this process removes most of the γ-oryzanol. The challenge is to develop a refining process which
Processing Technology of Rice Bran Oil
1. Introduction. Rice bran is a byproduct of the rice milling industry obtained from milling of brown rice to produce white rice. It contains 15%–20% of oil. Apart from oil, rice bran is a promising source for proteins, carbohydrates, dietary fiber, vitamins, tocopherol, γ-oryzanol, and phospholipids (Tao, 1989; Houston, 1972; Saunders, 1986).
Although the crude rice bran oil (CRBO) had high contents of both phytochemicals (1362–1376 mg phytosterol per 100 g and 1599–1666 mg γ-oryzanol per 100 g), physical refining process resulted in their reduction to 820–895 mg phytosterol per 100 g and 933–960 mg γ-oryzanol per 100 g in RBO (P < 0.05). Both phytochemicals evaporated

This research investigates the effects of different extraction processes on the oil extractability, oxidative stability, bioactive compounds, and antioxidant activity of crude rice bran oil (CRBO). The experimental extraction processes include hexane extraction (HE), cold press extraction (CE), thermally pretreated cold press extraction (CCE), and ultrasound-pretreated cold press extraction
Therefore, the present study was conducted to evaluate the quality and oryzanol content during the crude RBO refining process. Crude RBO was obtained by the reflux method using n-hexane as a solvent, followed by the dewaxing process by cooling and filtering procedure.
