Embodiment 1

[0037] A flexible peeling method for wheat bran, comprising the steps of:

[0038] Step I: remove impurities (including but not limited to stones, grass seeds and different grains) in the highland barley by cleaning, and then separate the highland barley with a cylinder classifier to obtain clean highland barley;

[0039] Step II: a flexible peeling, the highland barley is subjected to a flexible peeling with common flexible peeling equipment (corresponding to F1 below), and the temperature of the first flexible peeling is controlled below 40°C;

[0040] Step III: wheat conditioning, the wheat conditioning treatment is carried out on the highland barley after a flexible peeling, the conditioning agent is a concentration of 0.5% potassium bicarbonate solution, the addition amount of the conditioning agent is 15% of the mass of the highland barley, and the conditioning time is 30 minutes ;

[0041]Step IV: Secondary flexible peeling, after the highland barley after moistening i...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that in this embodiment, the blade assembly is not fixed on the rotating shaft, and a distance between the blade assembly and the rotating shaft 7 is provided for adjusting the distance between the blade assembly and the inner wall of the screen cylinder 6 Adjustment assembly, the adjustment assembly includes a connection seat and fastening bolts, the connection seat is an L-shaped structure, one end of the connection seat is welded and fixed on the outer wall of the rotating shaft 7, and the middle part of the other end of the connection seat is provided with a connection groove for inserting the blade connection part , the connecting groove is provided with a mounting hole, and the connecting part of the blade is provided with a bar-shaped connecting hole.

[0052] By setting the adjustment component, the distance between the blade assembly and the inner wall of the screen cylinder can be adjusted. After long-t...

[0055] Experimental example 1, the yield of bran

[0056] 1. Experimental design: Peel barley with the same quality (500kg) and the same batch of same quality. The specific experimental design is as follows. The detailed processing methods of F1-F6 in the process flow are as follows:

[0057] F1: Adopt ordinary flexible peeling, that is: the blade assembly is only equipped with blades, without rubber layer and grinding wheel;

[0058] F2: Peeling with the improved flexible peeling equipment of this scheme, that is: using blades, rubber layers and sand rollers for coordinated peeling;

[0059] F3: Peeling with the improved flexible peeling equipment of this plan, that is: using blades, rubber layers and sand rollers for coordinated peeling;

[0060] F4: Peeling with the improved flexible peeling equipment of this plan, that is: using blades, rubber layers and sand rollers for coordinated peeling

[0061] F5: Peeling with the improved flexible peeling equipment of this plan, t...

Abstract

The invention relates to the technical field of grain husking, and discloses a flexible husking method of wheat bran, which comprises the steps of primary flexible husking, wheat wetting and secondary flexible husking, in the wheat wetting step, a wheat wetting agent is a potassium bicarbonate solution, the concentration of potassium bicarbonate is 0.5-5%, the addition amount of the wheat wetting agent is 10-20% of the mass of net highland barley, and wheat wetting lasts for 30-80 min. The husking process of the highland barley can be relatively soft and relaxed through the operations of wheat wetting and two times of flexible husking, endosperm loss caused by excessive husking is avoided, in the wheat wetting process, the purposes of inactivating enzyme activity and stabilizing phytic acid can be achieved while effective wheat wetting is achieved by optimizing the wheat wetting agent, nutrient substances in the highland barley are reserved as much as possible, and enrichment of bran layers can be achieved.

Description

technical field [0001] The invention relates to the technical field of grain peeling, in particular to a method for flexible peeling of wheat bran. Background technique [0002] Highland barley (scientific name: Hordeum vulgare L.var.nudum Hook.f.) is an annual herbaceous plant belonging to the Poaceae family and the genus Barley. It is mainly distributed in Tibet, Qinghai, Ganzi Prefecture and Aba Prefecture in Sichuan, Gansu and other areas with higher altitudes. . Highland barley is the crop with the highest β-glucan among wheat crops in the world. According to the test, the average content of highland barley β-glucan is 6.57%, and the highland barley of fine varieties can reach 8.6%, which is 50 times the average content of wheat. The total dietary fiber content of highland barley is 16%, of which insoluble dietary fiber is 9.68%, and soluble dietary fiber is 6.37%. The former is 8 times that of wheat, and the latter is 15 times that of wheat. In addition, highland bar...
