Description
Technical field
The invention belongs to vegetable oil production to extract applied technical field, and in particular to a kind of preparation process of rice bran oil.
Background technology
Rice bran (existing national standards rice bran) is mainly to be processed into by pericarp, kind skin, perisperm, aleurone and embryo,
Therefore a small amount of rice husk and a certain amount of dust and microorganism can be infiltrated in process, be rice so being only used for feed
The principal by product of paddy processing, result of study and data both domestic and external show, various nutrients and physiological activity are rich in rice bran
Material.The developed countries such as the present U.S. have had edible rice bran to come out, and China also has similar products to be invented, i.e. the modern food of application
Product processing precisely grinds technology processed and seeks the not beneficial food matter (rice husk, pericarp, kind skin, dust, microorganism etc.) in rice bran with benefit food
Support material (outer layer such as embryo, aleurone endosperm) and carry out separation of precisely milling in clean workshop, this isolation technics can be by
Rice bran is classified as feed grade rice bran and food-grade rice bran two parts, and wherein food-grade rice bran accounts for the 80% of rice bran gross weight, battalion
Foster more than 90%, is that rice is ground although because food-grade rice bran only accounts for the 6% of paddy weight and accounts for about the 60% of paddy nutrition
Thing under stone roller during white, so it is also known as " meter Zhen " or " the rice dregs of rice ".
By the byproduct rice bran obtained during paddy processing, a kind of Rice oil produced with squeezing method or lixiviation process.When
Before be by NY/T 122-1989 (the existing country) standard《Rice bran》(oil-containing about 18%, by rice husk, dust, microorganism and secretion
Thing, pericarp, kind skin, perisperm, aleurone, embryo etc. are formed) standards of GB 19112-2003 produced can be used for eating《Rice bran
Oil》.Because the standard rice bran oil be rarely used in it is edible, be chiefly used in manufacture feed, soap, fixed oil, glycerine, stearic acid, oleic acid, oil
The raw materials of industry such as coating resins.
Currently, existing production prepare rice bran oil technique it is complex, and production cost is higher, and production efficiency is than relatively low
Under, and the rice bran oil produced is of poor quality, this be at present it is urgently to be resolved hurrily.

Row immersion, wherein, soaking time is -150 minutes 120 minutes, and the concentration of n-hexane or cyclohexane is 70%-80%, 15%-
25%.Step 6, step 5 is soaked after rice bran particle be put into industrial steam boiler carry out steam treatment, the rice bran after immersion
Particle becomes gas, wherein, steam copper in-furnace temperature is 200 degrees Celsius -210 degrees Celsius.Step 7, the steam importing by step 6
Condensing tower and progressively cool down, when temperature drops to 115 degrees Celsius -123 degrees Celsius, obtain rice bran oil liquid and collect；Work as condensation
When tower temperature degree drops to 58 degrees Celsius -63 degrees Celsius, obtain n-hexane or cyclohexane liquid and collect；When condensing tower temperature drops to 18
At degrees Celsius -22 degrees Celsius, obtain rice bran paving bits and collect.Step 8, the rice bran oil liquid detecting that step 7 is obtained, mistake
Filter, sterilize, then is detected by metal detector, packaging and storage, and n-hexane or cyclohexane cross metal detector and detect and be put in storage storage
Hide, rice bran paving bits drying is stored or made compost.
The technical program, the vapor (steam) temperature in the step 2 is 200 degrees Celsius, and the tablet drying temperature in step 4 is
85 degrees Celsius, water content is 7-7.5 water.
The technical program, soaking time is 120 minutes in the step 5, and steam boiler temperature is taken the photograph for 200 in step 6
Family name's degree.
The technical program, it is described when temperature drops to 120 degrees Celsius, obtain rice bran oil liquid and collect；Work as condensing tower
When temperature drops to 60 degrees Celsius, obtain n-hexane or cyclohexane liquid and collect；When condensing tower temperature drops to 20 degrees Celsius, obtain
Bits are spread to rice bran and are collected.
Compared with prior art, the beneficial effect of the preparation process of rice bran oil of the invention a kind of is：Its production technology
