Problems solved by technology

Although it can effectively peel and keep the oat grains intact, the peeling time is short in the whole peeling process, resulting in the process of oat peeling to retain the germ, the oat bran as a by-product cannot be completely peeled off, and the outer surface of the oat grains is still attached. Has a lot of oat bran

Embodiment 1

[0050] One set of peeling equipment is used, the peeling machine spindle speed of the peeling equipment is set to 550rpm, the power of the peeling equipment is controlled at 10kW, and the peeling time is extended by 10min. The structure of the peeling equipment is as follows figure 1 Shown, wherein, the diameter of emery roller is 2500mm.

[0051] Oat peeling and extracting oat bran operation: put the oat material to be peeled into the feeding assembly of the peeling equipment, and the propeller in the feeding assembly is driven by the power device to transport the oat material to the peeling chamber between the sand roller assembly and the sand board In the process, the oat material moves downward in a spiral motion driven by the sand roller assembly in the peeling chamber. During the spiral movement, the oat material passes through the action of the sand roller assembly and the sand plate to peel off the oat skin and extract oat bran.

Embodiment 2

[0053] Adopt 8 peeling equipments in series, the peeling mechanical spindle speed of each peeling equipment is set to 350rpm, the power of each peeling equipment is controlled at 15kW, and the peeling time is extended by 20min. The structure of the peeling equipment is as follows figure 1 Shown, wherein, the diameter of emery roller is 500mm.

[0054] Oat peeling and extracting oat bran operation: put the oat material to be peeled into the feeding assembly of the peeling equipment, and the propeller in the feeding assembly is driven by the power device to transport the oat material to the peeling chamber between the sand roller assembly and the sand board In the process, the oat material moves downward in a spiral motion driven by the sand roller assembly in the peeling chamber. During the spiral movement, the oat material passes through the action of the sand roller assembly and the sand plate to peel off the oat skin and extract oat bran.

Embodiment 3

[0056] Using 12 peeling equipment in series, the peeling machine spindle speed of each peeling equipment is set to 250rpm, the power of each peeling equipment is controlled at 18kW, and the peeling time is extended by 30min. The structure of the peeling equipment is as follows figure 1 Shown, wherein, the diameter of emery roller is 4000mm.

[0057] Oat peeling and extracting oat bran operation: put the oat material to be peeled into the feeding assembly of the peeling equipment, and the propeller in the feeding assembly is driven by the power device to transport the oat material to the peeling chamber between the sand roller assembly and the sand board In the process, the oat material moves downward in a spiral motion driven by the sand roller assembly in the peeling chamber. During the spiral movement, the oat material passes through the action of the sand roller assembly and the sand plate to peel off the oat skin and extract oat bran.

Abstract

The invention discloses an oat bran extracting process, which is used for extracting oat bran to the utmost extent on the premise of guaranteeing complete grains of oat by reducing oat husking speed by 30-60% and prolonging the husking time by 10-30 minutes. Nutrient in oat bran cannot be damaged when the oat bran extracting process is used for husking oat and extracting oat bran. The protein content of the extracted oat bran is increased by 50-100%, the beta-glucan content is increased by 30-50%, and contents of other effective components such as linoleic acid, vitamin are increased by 15-25%.

Description

technical field [0001] The invention relates to a method for processing oats, and further, the invention relates to a method for extracting oat bran. Background technique [0002] Oatmeal is rich in protein, amino acid, small molecular active peptide, dietary fiber, β-glucan, unsaturated fatty acid, calcium, phosphorus, iron and other trace elements, and has great economic value. The content of main nutrients per 100g of oats is shown in the table below: [0003] [0004] Oat bran is a by-product of oat processing. Oat bran contains the most abundant β-glucan in grains. Noble Dietary Fiber". [0005] More than 95% of the water-soluble fiber in oats is distributed in the oat bran after removing the endosperm. [0006] Water-soluble dietary fiber: Among natural grains, only oats and barley contain water-soluble dietary fiber, especially oat water-soluble dietary fiber β-glucan. Water-soluble dietary fiber (soluble dietary fiber) can absorb a large amount of cholesterol ...
