Rice bran is the main by-product of rice processing, accounting for about 6% of the weight of rice. The oil content of rice bran is 12%~23%, and the oil content is low, but the unsaturated fatty acids in the extracted rice bran oil are as high as 80%, which is a very potential vegetable oil. In addition, it is rich in nutrients such as oryzanol, phytosterols, squalene, vitamin E, etc., which are beneficial to human health.
Currently, there are two commonly used rice bran oil processing processes: pressing and extraction. The pressing process is not very ideal for rice bran, which has a low oil content and high powder content. Most manufacturers will choose the extraction process to process rice bran oil. Rice bran has the disadvantages of easy rancidity, poor oxidative stability, and difficulty in centralized collection. Fresh rice bran is very easy to rancid after rice milling, which affects the subsequent oil extraction and oil quality. Therefore, the stabilization treatment of rice bran is the key to producing high-quality rice bran oil and its deep processing and utilization.
Extrusion is widely used in oil processing enterprises, and is often used to stabilize rice bran and inhibit lipase activity. Extrusion can extend the shelf life of rice bran and lay a good foundation for subsequent processing of rice bran. The extrusion-extraction process is also a common process for producing rice bran oil in industry. The extrusion-extraction process is to extrude and puff the cleaned rice bran raw materials first, and puff the raw materials with high powder content into granular materials with good permeability, and then send them to the rice bran oil extraction machine to use solvents to extract the oil. The extrusion-extraction method for producing rice oil has the characteristics of easy large-scale production and can significantly improve the oil yield.
For investing in a rice bran oil extraction production line, the quality of the extraction equipment and the extraction process have a great impact on production efficiency and finished product oil yield. The manufacturer’s technical strength and project experience are also the key to ensuring safe production in the rice bran oil plant.
