The present invention relates to a processing method of the granules that can be mixed with rice uniformly.

The barley is lighter than rice, so when it is cooked together, it is punched in a part. As the seed ball located in the center of the particle is easily decayed, it has a poor shelf life and emits a distinctive odor. Fermentation, filling and release of gas in the intestine, softening (軟化) is slow, because the simultaneous cooking with rice is difficult, taste is unpleasant, starch (함유) containing is mainly in β state, there was a problem of low digestibility.

In order to improve the drawbacks of the barley described above, various improvements have been made in the prior art. For example, in Japanese Patent Application Nos. 34-468, 35-3810, and 45-27376, barley particles are easily removed. After cutting (so-called venous vein) and milling, the starch of the barley in β-state is made to be easily decomposed α starch (so-called α) and dried, squeezed or expanded (Iii) a processing method was introduced.

However, in such a conventional method, the coating is mainly performed in a state in which a relatively weak starch layer is exposed, so that the yield of the product is very low and a large amount of moisture is added. Since the α-starch, which has high viscosity, is entangled with each other and the phenomenon of the product is not homogenized, and excessive drying is performed to improve the preservation of the product, the specific gravity is smaller than that of raw barley, making it difficult to mix with rice As the starch returned to the β state again, many small cracks were generated on the surface of the particles (so-called aging), resulting in various problems with poor taste, appearance, or digestibility.

Accordingly, the object of the present invention is to solve the above-mentioned problems, the appearance and specific gravity is similar to the rice can be uniformly mixed, the water absorption rate and softening rate is also similar to the simultaneous cooking with rice is possible, high digestibility, smooth It is to provide a processing method that can produce a tachycardia that is tasteless and has a smooth and waxy taste.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, the barley particles (1) are put into the sorting machine to remove impurities such as soil, dust, stones and sand, and unsorted and small grains to sort out only the grains.

Next, the skin is removed by friction coating, and the coating is performed up to 80-85% by grinding, etc. (primary coating process).

Subsequently, the barley particles are cut along the seed mouth 4 by a cutter to form a split vein 6, and the uncut cut vein is sorted out. At this time, in order to prevent the particles from being crushed during the cutting process, it is preferable to adjust the moisture appropriately with a continuous water feeder before cutting.

The grinding operation is then performed to remove part of the steel layer 3 and the seed ball 4, thereby killing the angle of the cut surface 7. (Secondary milling process)

(For example, in the prior art such as JP 45-27376, the second milling process has completed the milling up to l00%, but the relatively strong steel layer 3 and the weak starch layer 5 are exposed simultaneously. Since the milling is carried out in the prepared state, the starch layer 5 is more easily ground than the steel layer 3, and the yield of the product is very low after the milling is completed. And partial drawing of a degree of killing a part of the steel layer 3 and the angle of the cutting surface 7).

Next, cold water is washed for 5 minutes with an immersion tank or a continuous water supplyer to absorb water to obtain a water content of about 25-35%, and then preheat the vein 6 with a saturated steam at about 105 ° C. And the primary steaming to partially α the starch of the vein. (First steaming process)

At this time, condensate is generated on the surface of the clave due to excessive water supply, and the starch layer 5 exposed by cutting is hydrolyzed to form a colloidal solution of starch having a very high viscosity in the condensate. In order to prevent tangling with adjacent clavary particles, in the present invention, after the first steaming step by saturated steam, the secondary steam is performed by the superheated (dry) steam of 130 ° C. to 140 ° C. to partially dry and Α conversion is performed simultaneously (secondary incremental process).

(In the prior art such as Japanese Patent Application No. 45-27376, the coating process is completed up to 100% in the secondary coating process to completely α-starch in excessive water supply to form a colloidal solution of very high starch. Tangling with cleavage particles, which makes the final product uneven and difficult to follow up)

The granules are partially dried to the extent that the granules are not entangled with each other, and the starch is completed by forming a starch roller, which is pressed by a forming roller and pressed flat to form a granule similar to rice. The process differs from the conventional compacting process in that the compacting of the conventional process is performed for drying the particles and adjusting the specific gravity, but the process of the present invention adds the purpose of forming into a rice grain shape.

After the molding is completed, the granules are sent to a blower, or the like, and firstly dried in a rotary dryer (first low tide process), and then rapidly dried at a high temperature with hot air at 120 ° C. to 140 ° C. to adjust the water content to about 16%. Drying process)

In this way, aging is prevented by rapid drying at high temperature, so that the bran has stable alpha particles of translucent color, and the starch tissue is densified to adjust the specific gravity similarly to rice. Residual steel layers and species with small shrinkage) coefficients are exposed to the surface of the particles and are induced to be easily removed.

The remaining steel layer (3 ') and the remaining seed ball (4') exposed to the surface by the secondary drying process are removed by grinding, etc. to complete the whitening (third milling) process friction milling, etc. After polishing to make the surface gloss, sort out circular veins and crushed particles.

At this time, the solution is infiltrated by heating and spraying an aqueous solution of vitamin (for example, vitamin B1 Thiamin Di-Benzoil or thiamine nitrate (aqueous solution of Thiamin Nitrate, etc.) or seasoning or nutrient) between the third milling process and the polishing process. Drying may be added to enhance the nutrition process.

According to the processing method of the present invention as described above, the appearance, specific gravity, cooking and softening rate is similar to rice, which is possible to simultaneously cook, but also good taste and high digestibility, the appearance of the particles can be produced with a beautiful translucent gloss, By improving the preference for barley, the ripple effect is very great, such as the reduction of rice consumption by replacing the grains.
