Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Millet oil bran oil extraction process is characterized in that: comprising the following steps;

[0025] (1) Peel the millet with a husker and become millet after peeling;

[0026] (2) The millet is sent to the first polishing machine through the hoist, and the rough fiber of the outer layer of the millet is peeled off by the polishing machine to obtain the millet grain exposing the millet germ, and the outer thick fiber polished for the first time is discarded . During the first polishing process of millet in the polishing machine, the millet grains fall under the action of gravity, and the polished crude fiber is introduced into the first collector connected with the working room of the polishing machine by the negative pressure fan. There is no grease in it, so it is discarded;

[0027] (3) The millet grains exposing the...

Abstract

The invention provides a process for extracting oil from millet bran absolute, which is improvement for an oil expression process by using millet bran absolute. The process comprises the following steps: (1) hulling grains with a hulling mill to obtain millet; (2) feeding the millet into a first polishing machine by virtue of an elevator, and peeling crude fibers on the outer layer of the millet through the polishing machine; (3) enabling the millet kernels with exposed millet embryos after outer coarse fibers are removed to flow into a second polishing machine, mixing the millet embryos and peeled surface fine flour to form millet bran absolute (polishing flour); (4) coating the millet bran absolute (polishing flour) with a filter cloth to form a raw material package, and putting into an oil pressing frame of a cold press; and (5) starting a presser, slowly pressurizing, extracting oil from materials when the pressure is between 30-50MPa, and enabling grease to flow from the lowermost gap of the presser to obtain crude oil.

Description

technical field [0001] The invention is an improvement of the oil extraction process using millet oil bran. Background technique [0002] Millet has another name called millet, Poaceae, is a kind of annual herbaceous plant, and it likes warmth in nature, and adaptability is strong. Originated in the Yellow River Basin of my country, it has a long history of cultivation in my country, and is now mainly distributed in North China, Northwest and Northeast China. Millet is rich in protein, fat, carbohydrates, vitamins and minerals, and also rich in trace elements, so it is often used as a high-quality food for nourishing yin and calming the nerves. However, there are not many studies on its processing by-product, millet bran. Millet bran has been sold to major feed factories for animal feed, which greatly wastes precious resources. In fact, due to the existence of embryos in millet bran, it contains oil, which is a source of high-quality oil. Further processing it is beneficia...
