Rice bran oil summaryRice bran oil is the oil extracted from rice bran, which is the by-product of milling brown rice into white rice.The oil content of rice bran varies with the quality of rice bran, and the oil yield is generally 10%~12%, and higher than 15%.
Main Oil making Process Crude rice bran -cleaning -softening -expansion -drying -to extraction plantExtrusion machine Oil material after extrusion, puffing material grain density increase, oil material cells are completely destroyed, have more space inside, outside surface have more free oil, grain size and mechanical strength increase, at the time of extruding, solvent permeability is dramatically improved to material layer, extruding rate improve, short extruding time, thus can make the yield increase of extruder. After extracting, the solvent content of wet meal is lower than oil material extracting directly. Due to the improvement of the permeability of the material layer by solvent during the oil leaching.At the same time, the output of the wet meal dissolving equipment is increased and the energy consumption of the wet meal dissolving equipment is greatly reduced.
Rotocel extractorThe oil yield of oil extracted by extracting method is higher than that by press method, and the residual oil of oil meal extracted by extracting method is less than 1%, which is of practical significance for rational utilization of oil resources. Secondly, after oil extraction, the protein content of oil meal was relatively high and the quality was good, which could be used as raw material for video and feed production. Thirdly, the production scale has low processing cost. Fourth, high degree of automation control, leaching of the combination of French chemical units, it is easy to achieve automatic control of temperature, pressure, liquid level, vacuum, flow, material level. Fifth, the production environment is good, because it is closed production, no leakage, no dust, and low temperature, the production environment is better than the pressing method.
Advantages of Rotocel extractor
1. Simple in structure2. Reliable operation3. Low power consumption4. Small footprint5. The mixture is highly concentrated6. The mixed oil contains few impurities7. The leaching effect is good
Toast-desolventizing sectionWet meal discharged from bottom of extractor is sent to pre-desolventing layer of DTC desolventizer-toaster by wet meal scraper conveyor, heating with indirectly steam and make part of the solvent evaporating, temperature of meal rising; After pre-desolventizing, the wet meal is sent to pre-toast-desolventizing layer, pre-toast-desolventizing solvent in meal by secondary steam at toast-desolventizing layer, and then the meal fall into toast-desolventizing layer, filling in directly steam and the steam spraying into meal from bottom hole, steam distillation for solvent in meal to remove the solvent, part of the steam condensation in the meal, play an active role in destroying enzyme activity of meal; desolventized meal fall into lower drying layer from discharge valve, and drying the meal to make the moisture in it achieve the requirements of bagging and storage.
Evaporating section Miscella temporary storage and further clarified in miscella tank, sediment at the bottom of miscella tank is pumped back to extractor by residue pump; clarified misclla go into the first evaporator, steamed solvent vapour come into first evaporation condenser from the top of vapour-liquid separation chamber of the first evaporator, miscella go into the second evaporator, steamed solvent vapour come into the second evaporation condenser together with solvent vapor from the first evaporator, further concentrated miscella flow out from flash tank of the second evaporator, go into stripper from top of the disk stripping colum, filling direct steam from bottom of stripper, removing the residual in miscella, the mixed vapour go into stripping condenser, crude oil go into the crude oil tank and is sent to tank yard or refining workshop by a pump.Process introduction of refining plantCrude oil-Dephosphorization, degumming, drying and decolorization-Deacidification and deodorization- Dewaxing- Finished oil- Filling
