Rice bran oil, a healthy edible oil with high nutritional value, continues to see growing market demand. However, efficient and safe processing of rice bran oil is a key concern for oil mills when investing in production lines. Below, we'll provide a detailed introduction to the machinery required for a rice bran oil production line.
Rice bran oil is processed primarily using two processes: pressing and solvent extraction. Because rice bran has a low oil content (15%-23%) and is prone to rancidity, solvent extraction has become the mainstream method in the industry due to its high oil yield (residual oil rate <1%) and stable production efficiency. The following is a list of core equipment for the extraction process:
Rice bran pretreatment is a critical step in rice bran oil production, directly impacting subsequent extraction efficiency and oil quality. Fresh rice bran is prone to rancidity and deterioration, so it requires processing through a series of pretreatment equipment to control the rapid increase in acidity and prevent oil loss.
Cleaning equipment : magnetic separators, vibrating screens, etc., to remove impurities and metal particles and protect subsequent equipment.
Conditioning tank : adjusts the temperature and moisture of rice bran to make it reach a good state before expansion, preparing for subsequent puffing process.
Puffing machine : The rice bran is puffed into porous particles through high temperature and high pressure, which improves the solvent penetration efficiency, deactivates enzyme activity and improves the leaching efficiency.
Counter-current dryer : Dry the processed rice bran to reduce the moisture content for easy storage and transportation.
The solvent extraction equipment in the rice bran oil pressing equipment is an important equipment for extracting rice bran oil from rice bran cake by solvent extraction. The oil in the cake is extracted by spraying and soaking with solvent to obtain mixed oil and wet rice bran meal.
Extractor : Use a horizontal rotary extractor or loop type extractor. The rice bran cake enters the extractor and the oil in the cake is extracted through solvent spraying and soaking to obtain mixed oil and wet rice bran meal.
Evaporation tower : The wet meal enters the evaporation tower for desolventizing and drying to obtain a dry cake that meets the solvent residue standards.
Mixed oil evaporation system : The mixed oil enters the mixed oil evaporation system, where the crude oil and the solvent are separated by evaporation and stripping.
Mixed oil condensation recovery system : The solvent is recovered after cooling so that the solvent can be recycled, and the obtained rice bran crude oil enters the refining workshop.
Crude rice bran oil contains impurities, free fatty acids, waxes, etc., and needs to be refined to obtain finished oil that meets national standards.
Degumming equipment : phosphoric acid reaction tank, to remove phospholipids and other colloid components in crude oil.
Deacidification equipment : neutralizes free fatty acids and reduces acid value.
Decolorization equipment : Use activated carbon or bleaching earth to absorb pigments to make the oil color clearer.
Deodorization equipment : Physical deodorization process retains nutrients and improves taste.
Dewaxing equipment : Aiming at the waxy problem unique to rice bran oil, the specially designed dewaxing process can significantly improve the transparency of the oil.
Turnkey project: From pretreatment to refining, we provide full-process solution design, installation and commissioning.
Patented technologies: such as expanded leaching process and negative pressure evaporation system, leading the industry in residual oil rate.
Global Cases: The equipment has been exported to Nicaragua, Pakistan, Bangladesh and other regions to adapt to diverse raw materials.
