Millet bran (germ) oil extraction machine

The millet bran oil extracted from millet bran is rich in unsaturated fatty acids, vitamin E, glutenin, phytosterols and other nutrients. However, most of millet bran is directly fed to livestock or poultry as feed after grain processing, making its utilization rate and added value very low, and it is a vegetable oil resource with development potential . The research on the amino acid composition of millet bran finds that the essential amino acid content is richer, the ratio of essential amino acid and non-essential amino acid is more reasonable, and the protein in millet bran is closer to the ideal protein requirement. The cellulose and hemicellulose content in millet bran is rich, and it is an important dietary fiber resource, and the research finds that the dietary fiber in millet bran has the function of reducing blood sugar content and regulating blood lipid. Millet bran oil is rich in linoleic acid, also contains functional components - squalene, research shows that millet bran oil has the effect of inhibiting melanin generation, anti-skin photoaging, lowering blood lipids and antioxidant.

Raw material.

Fine bran is taken from the first and second process of grain peeling (fine bran accounts for about 2.5% of grain weight); polishing powder is taken from the third process of grain peeling (polishing powder accounts for about 5% of grain weight).

The moisture content and crude protein content of polished powder are greater than fine bran, while the crude fat content and ash content are lower than fine bran, especially the cellulose content is significantly lower than fine bran. This is because the fine bran is the first and second process in the processing of millet, inside the peel layer (bran) content more, crude fiber content is high, and polishing powder is the third process of processing millet as fine rice process, mainly which is paste powder layer, millet embryo, broken rice and millet powder, so the crude fiber content is very low, but because it contains more rice ground rice also causes the crude fat content is relatively low.

Because in extracting millet bran oil usually mix the two together as raw material, therefore according to the ratio of both in the grain will be fine bran and polishing powder 2:1 mix, called mixed bran that is whole bran.

Extraction of rice bran oil

Extraction of millet bran gross oil by pressing method: Because the oil content of millet bran is low, and it is the powder with loose texture and irregular fine grain shape, which is not good for oil. Therefore, we have to steam billet treatment for millet bran, take 1,000 g each of fine bran, polishing powder and mixed bran raw material respectively, first adjust the moisture mass fraction to 16%, put it into 105 ℃ oven and bake for 30 min

Put them into hydraulic oil press chamber for pressing, and get the corresponding fine bran pressing oil, polishing powder pressing oil and mixed bran pressing oil.
