Embodiment 1

[0037] Take 2kg of wheat bran and place it in a 20-mesh rotary vibrating sieve (product of Xinxiang Gaofu Screening Machinery Co., Ltd., model: S49-400) for vibratory sieving for 20 minutes to remove residues on the inner surface. Starch, take the sieve; use a blade mill (product of Shanghai Bingdu Electric Co., Ltd., model: Q-500B3) to crush the above-mentioned sieve obtained after impurity removal to a particle size of 400 μm, pass through a 20-mesh standard sieve, and take the sieve Undercuts; the pre-crushed undersizes were dried in an oven at 40°C for 30 minutes until their moisture content was 9%; turbine pulverizers (products of Jiangyin Longchang Machinery Manufacturing Co., Ltd., model: DWFJ-5) were used to The dried wheat bran is crushed at low temperature, the gas intake temperature of the crushing chamber of the turbo mill is set to -15°C, the temperature at the material outlet is 10°C, and the working frequency of the millstone is set to 40Hz; the particle size aft...

Embodiment 2

[0039] Take 2kg of wheat bran, place it in a 20-mesh rotary vibrating sieve (same as above) and carry out vibratory screening for 25 minutes to remove the residual starch on the inner surface, and take the sieved material; use a blade grinder (same as above) Crush the above-mentioned oversize obtained after impurity removal to a particle size of 600 μm, pass through a 20-mesh standard sieve, and take the undersize; seal the above-mentioned pre-crushed oversize and place it in a -18°C environment for pre-cooling for 30 minutes; use a turbine The type pulverizer (same as above) crushes the frozen wheat bran at a low temperature. The air inlet temperature of the pulverization chamber of the turbo pulverizer is set at -15°C, the temperature at the material outlet is set at 10°C, and the working frequency of the grinding disc is set at 45Hz; Repeat the above low-temperature grinding operation for wheat bran particles with a particle size greater than 250 μm after low-temperature gri...

Embodiment 3

[0041] Take 2kg of wheat bran, place it in a 20-mesh rotary vibrating sieve (same as above) for vibration sieving, and sieve for 30 minutes to remove the residual starch on the inner surface, and take the sieved material; use a blade grinder (same as above) Crush the above-mentioned oversize after removing impurities to a particle size of 800 μm, pass through a 20-mesh standard sieve, and take the oversize; place the above-mentioned pre-crushed oversize in an oven at 40°C for 30 minutes to dry until its moisture content is 10% ; The frozen wheat bran is crushed at low temperature using a turbine pulverizer (same as above). The gas intake temperature of the pulverization chamber of the turbo pulverizer is set at -15°C, and the temperature at the material outlet is set at 10°C. The frequency is set to 50Hz; the wheat bran particles with a particle size greater than 250 μm after low-temperature grinding are repeatedly subjected to the above-mentioned low-temperature grinding opera...

Abstract

The invention provides a preparation method of wheat bran aleurone which is prepared by taking wheat bran as raw material. The preparation method comprises the following steps of: removing impurities, precrushing, predrying/prefreezing, crushing at low temperature, enriching, carrying out air classification and grading or high-voltage electrostatic separation, sterilizing and packaging to obtain an aleurone finished product, wherein the operations of removing impurities and enriching are carried out in a spin-vibration screen, the operation of crushing at low temperature is carried out through a turbo type crusher at the crushing temperature ranging from 15 DEG C below zero to 10 DEG C, and the operation of high-voltage electrostatic separation is carried out in a high-voltage direct-current electrostatic field. As a dry method for machining and treating, the method provided by the invention can be used for remaining the nutritional ingredients of the aleurone to the maximum extent and is good in separation effect for an aleurone layer, high in purity of the prepared aleurone finished product, simple in process flow and low in production cost.

Description

technical field [0001] The invention belongs to the field of agricultural by-product processing, and in particular relates to a method for preparing aleurone by using wheat bran, a by-product of wheat processing, as a raw material. Background technique [0002] Wheat bran is a by-product of wheat flour processing. It is the outer edge tissue of wheat grains. It can be roughly divided into three structural layers: the outer cortex, the middle layer and the aleurone layer. Among them, the main component of the outer cortex is cellulose, and the middle layer includes the endocarp. , transverse cells, seed coat and transparent layer, the main component of which is hemicellulose, the aleurone layer is composed of a single layer of large cells, accounting for 6-9% of the weight of wheat grains, 40-50% of the weight of wheat bran, mainly composed of The composition is composed of the cell wall of dextran and the contents of loose fat particles and protein particles, and is combined...
