Embodiment 1

[0024] The present embodiment discloses a rice skin powder and a production process thereof, comprising the following steps,

[0025] A. Send the paddy into the hulling machine for shelling;

[0026] B, pass the paddy that has been husked through step A into a gravity paddy separation sieve to obtain brown rice;

[0027] C, the brown rice in the preferred step C is milled for the first time, milled for the second time and milled for the third time respectively, and the powder obtained by the milling for the third time is primary powder;

[0028] D. Sifting the primary powder obtained in step C to obtain rice skin powder.

[0029] In this embodiment, the three milling processes are consistent, that is, the brown rice is successively fed into three emery roller rice mills for three millings. For the first milling, the obtained powder is more yellow, mostly chaff; for the second milling, the powder obtained is slightly yellow, mainly the peel; for the third milling, the powder ...

Embodiment 2

[0037] The main difference from Example 1 is that the number of mesh sieved in step D of this example is 60 mesh. The rice skin powder that described step D obtains is further dried. Reduce the moisture content in the rice peel powder, prevent the rice peel powder from agglomerating during storage and transportation, prevent the rice peel powder from deteriorating and becoming moldy, benefit the obtaining of high-quality rice peel powder, and prolong the storage time of the rice peel powder. The rice skin powder in the step D is passed into a fluidized bed for drying, and the drying temperature is 50-60° C., and the moisture in the rice skin powder is 8% from 13% by mass, and the moisture content in the rice skin powder is strictly controlled to prevent The rice skin powder is agglomerated and moldy. After passing through the fluidized bed, the rice skin powder is loose and uniform, and the seed coat, aleurone layer and endosperm in the rice skin powder are further uniformed t...

Embodiment 3

[0042]The main difference from Example 1 is that the number of mesh sieved in Step D of this example is 80 mesh. In this embodiment, the rice skin powder obtained in step D is subjected to continuous microwave heating, and the process conditions of microwave treatment are: 560W microwave treatment for 45s. After microwave stabilization, the mass percentage of rice skin powder moisture decreased from 14% to 7%. At the same time, it destroyed the lipolytic enzymes present in the transverse cell layer of the seed coat, and also eliminated microorganisms. Microorganisms mainly include bacteria, actinomycetes, and molds. , saccharomyces, phytopathogenic fungi, etc., therefore, the rice skin powder obtained in this embodiment can prevent lipolytic enzymes from contacting the fat in the aleurone layer and the germ, causing the rice skin powder to rot with oleic acid, and eliminating the fat in the rice skin powder Microorganisms can prevent the rice skin powder from agglomerating and...

Abstract

The invention discloses rice skin powder and a production technology thereof. The production technology comprises the following steps that A, rice is conveyed into a rice huller for unshelling; B, therice obtained after unshelling in the step A is led into and passes through a gravity rice rough separation sieve, and brown rice is obtained; C, the brown rice is led into an emery roll rice mill tobe ground at least two times, and powdery objects obtained after last-time grinding are taken to serve as primary powder; and D, the primary powder obtained in the step C is sieved, and the rice skinpowder is obtained. According to the rice skin powder and the production technology thereof, the rice skin powder is obtained in the process that rice is processed into polished rice, usage equipmentis simple, and operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of grain processing, in particular to a rice hull powder and a production process thereof. Background technique [0002] Harvested rice grains usually have a multi-layer structure, from the outside to the inside, there are chaff, bran, aleurone layer, endosperm, germ and germ. After removing the chaff of the rice grains, brown rice with bran is obtained, which is further ground Polished rice is obtained by removing the husk, germ and part of the endosperm on the surface of brown rice. [0003] Rice bran is a by-product of rice processing. It is the surface layer attached to brown rice after husking. It is composed of exocarp, mesocarp, cross-linked layer, seed coat and aleurone layer. 5% to 5.5%. Brown rice is composed of three parts: rice bran layer, germ and endosperm. The polished white rice we eat every day is brown rice with the rice bran layer and germ removed, and the mixture of rice bran layer and...
