Abstract

PROBLEM TO BE SOLVED: To make it possible to recover a wheat-gluten bread usable as food by each of segments varying in components by executing recovery of skin parts after removal of the surface layer parts of the skin parts with an apparatus for dividing the skin parts successively removed from the surface parts of raw material barley by barley milling to plural segments and recoverying. SOLUTION: Raw material barley supplied to a supply port 28 is successively fed by a spiral rotor 11 into a grinding and milling chamber 13 and while the barley rolls and flows down under revolution, the skin parts of raw material barley are gradually ground off from the outermost layer side by a grinding rotor 7 and the bran leaks into a bran removing chamber 15A. The bran is recovered into a bag filter via a duct 17A. The bran removed gradually from the outer layer side of the skin parts is successively leaks from the outer side of the skin parts into bran removing chambers 15B to 15D from which the bran is recovered through the ducts 17B to 17D. The barley brains subjected to the polishing in the grinding and milling chamber 13 is supplied from a discharge port 18 through a communicating passage 21 to a friction milling section 10 where the bran is supplied to a friction milling chamber 26 by a spiral rotor 24 from a supply port 27.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recovering wheat bran by recovering the bark, which is sequentially removed from wheat grains by a crushed barley, into a plurality of sections.

[0002]

2. Description of the Related Art As shown in FIG. 2, wheat endosperm as a product powder is composed of an outer skin (approximately 0.5% by weight of wheat grain), an intermediate tissue,
It is covered with a rind composed of a pericarp formed by horizontal cells and duct cells, a seed coat, and an aleurone layer formed by aleurone layer cells. The skin has a high ash content, and if the skin is mixed into the product powder obtained by grinding, the quality of the product powder will be reduced, so that the endosperm is collected in powder form so that the skin is less mixed. Efforts are being made to increase flour collection rates.

[0003] In order to reduce the mixing of the bark into the product flour, so-called crushed barley milling, in which the bark of the raw material barley is removed in advance before grinding, is performed.

[0004] The bark removed from the raw wheat is mainly used for feed as "Fu" (bran), but "Fu" is rich in dietary fiber, vitamins, minerals, proteins and the like. It is attracting attention as a health food.

Japanese Unexamined Patent Publication (Kokai) No. 2-184347 discloses a method of rectifying raw barley in a stepwise manner using a plurality of mulling machines and recovering the skin from each mulling machine. In this method, the raw wheat, from which debris and dirt attached to the surface have been removed, is subjected to a friction treatment with a friction-type mulling device, and then a grinding treatment with a grinding-type mulling device to produce refined wheat (wheat grains from which the skin is removed). In addition, it is described that, in addition to recovering fiber rich in dietary fiber or protein, etc., from each cereal apparatus, the recovered fiber is added to flour, for example, to increase the amount of fiber in flour.

[0006]

It is important that the san is sanitary when the collected san is treated as food. In the above-mentioned barley method, although the dirt attached to the surface of the raw wheat is removed in advance to remove the dirt and then the wheat is recovered to recover the wheat, the bacteria and mold that have entered the surface layer of the raw wheat are sprayed for controlling pests. No consideration is given to pesticides and the like that have infiltrated into the surface layer of the raw wheat, and for this reason, there is a high possibility that these harmful substances will be mixed in the collected fish. Can not.

[0007] It is a technical object of the present invention to provide a method for recovering wheat bran, which can recover fu, which can be used as food, for each of the different categories of components.

[0008]

Means for Solving the Problems In order to solve the above-mentioned problems, a method for recovering wheat bran according to the present invention is a method for recovering wheat bran by recovering the bark, which is sequentially removed from the surface portion of the raw material wheat by a crushed wheat into a plurality of sections. In the recovery method, a technical measure was taken in which the skin was collected after the surface layer of the skin was removed.

[0009] The bark is collected by using 0.5 to
Performed after 1.0% rye.

[0022]

EXAMPLES As raw wheat, C.I. W. R. Using S (Canadian Western Red Spring Wheat), the above-mentioned wheat mulching apparatus 1 was used to refine the wheat and analyze the bran component of each section. The yield of the raw wheat when passing through each of the partition plates 16A to 16D, 29A, and 29B was 9% for the partition plate 16A.
9.5%, partition plate 16B 98.0%, partition plate 16C 96.4%, partition plate 16D 95.0%, partition plate 29A
Was 93.4%, the partition plate 29B was 91.9%, and the yield of the wheat grains discharged from the discharge gutter 35 was 90.6%.

[0023]

[Table 1] This table shows that each duct 17B (yield 99.5 to 98.
0%), 17C (yield 98.0-96.4%), 1
7D (yield 96.4 to 95.0%), 31A (yield 95.0 to 93.4%), 31B (yield 93.0 to 93.4%).
4-91.9%), 31C (yield 91.9-90.
6%), and the amounts of the specific components of the bran recovered from the rice bran are shown in FIGS. 3 and 4.

The protein content increases with decreasing yield, the dietary fiber and pentosan content decrease with decreasing yield, and the mineral content increases with a yield of 95.
When the yield is 96.4 to 95.0%, the most is present when the yield is from 96.4 to 95.0%. As described above, the content of bran is different for each yield. For example, when bread is produced by adding 99.5% to 98.0% of bran to wheat flour, dietary fiber and pentosan And bread with a rich crumb color. Pentosan can suppress aging of bread without adding an emulsifier or the like due to its high water retention capacity. When bread is manufactured by adding bran having a high protein content and a yield of 93.4 to 90.6% to flour, the bread becomes large and plump due to the action of gluten. Also,
Bran with a yield of 99.5 to 98.0% and a yield of 96.4
When bread is manufactured by mixing 糠 95.0% bran and adding this mixed bran to flour, it is possible to manufacture bread rich in dietary fiber and vitamins.

[0025] The amount of bran added to the flour, the section or the mixing ratio of each section is appropriately adjusted depending on the desired bread component.

[0026]

As described above, in the method for collecting wheat bran in which bark is sequentially removed from the surface of the raw material barley by means of refined barley and collected in a plurality of sections, the bark is recovered by removing the surface layer of the bark. Bran can be collected after removing bacteria, mold, pesticides, and the like that have entered or penetrated into the surface layer of the pericarp by performing it later, and since the collected bran is sanitary, the addition of bran to foods Is possible.

[0027] The raw material barley may be collected from 0.5 to
By performing the processing after 1.0% pearling, the outer skin that forms the outermost layer of the wheat grain can be reliably removed from the wheat grain, thereby preventing bacteria, mold, pesticides and the like from being mixed into the bran. Because the collected bran is hygienic,
Bran can be added to food.
