상기 헤드(6)는 제2도 및 제3도에서와 같이 중앙일측에 상기 스크류우(4)의 자유단이 내설되게 구멍(9)을 형성하며, 또한, 그 부위의 내주면에 집적 원홈(10)을 형성하고, 타측에 원호상으로 다단식 노즐구멍(11)을 다수개 형성한다.As shown in FIGS. 2 and 3, the head 6 forms a hole 9 so that the free end of the screw 4 is installed at one central side thereof, and the integrated circular groove 10 is formed on the inner circumferential surface of the portion. ), And a plurality of multi-stage nozzle holes 11 are formed on the other side in an arc shape.

또한, 상기 헤드(6)는 원주면에 플랜지(12)를 형성하여 상기 실린더(3)의 제3실린더(3c)에 보울트와 너트로 고정시켜 일체화 한다.In addition, the head 6 is integrally formed by fixing the bolt 12 and the nut to the third cylinder 3c of the cylinder 3 by forming the flange 12 on the circumferential surface.

상기 호퍼(7)는 실린더(3)의 제1실린더(3a)의 상부에 설치하여 상기 스크류우(4)의 회전시 호퍼(7)내에 저장된 곡류가루가 제1실린더(3a)내로 자연공급되게 한다.The hopper 7 is installed on the upper portion of the first cylinder 3a of the cylinder 3 so that the cereal powder stored in the hopper 7 is naturally supplied into the first cylinder 3a when the screw right 4 rotates. do.

한편 상기 습열팽화기 본체(1)의 헤드(6)측과 일정거리가 유지되게 분쇄장치(도면에 미표시)를 설치하여 습열팽화기 본체(1)에서 사출성형된 팽화 곡류를 분쇄하여 팽화 곡류가루를 만든다.Meanwhile, a pulverization apparatus (not shown) is installed to maintain a predetermined distance from the head 6 side of the moist heat expander main body 1 to pulverize the expanded molded grains in the moist heat expander main body 1 to expand the expanded grain powder. Make

이와같이 구성된 본 발명은, 호퍼(7)내에 곡류를 20-50메쉬 통과율이 100%가 되도록 분쇄한 곡류가루를 저장한다.According to the present invention configured as described above, grains obtained by crushing the grains in the hopper 7 so as to have a 20-50 mesh passage rate of 100% are stored.

이때, 상기 곡류가루는 일반적으로 수분이 13% 포함되어 있고 호퍼(7)내에 저장시 곡류가루와 함께 물을 곡류가루량의 약 6-10%정도 혼합시켜 6-10%정도의 물이 곡류가루에 골고루 흡습되도록 한다.At this time, the grains generally contain 13% of moisture, and when stored in the hopper (7), water is mixed with grains of about 6-10% of the amount of grains, 6-10% of the grains Make sure to absorb moisture evenly.

따라서, 모타의 구동에 의하여 스크류우(4)가 회전하게되면 호퍼(7)내의 곡류가루가 스크류우(4)에 의하여 제1실린더(3a)내로 자연공급되어 제2실린더(3b)측으로 이송된다.Therefore, when the screw 4 is rotated by the driving of the motor, the grains in the hopper 7 are naturally supplied into the first cylinder 3a by the screw 4 and transferred to the second cylinder 3b. .

이때, 실린더(3)의 제1,2,3실린더(3a)(3b)(3c)의 내부온도는, 제1실린더(3a)는 90-110℃, 제2실린더(3b)는 170-190℃, 제3실린더(3c)는 230-250℃의 온도를 유지하여 제1실린더(3a)에서는 호정이 이룩되게 하고, 제2실린더(3b)에서는 α-화(익힘)되게 하며, 제3실린더(3c)에서는 곡류가루와 포화증기가 압축되도록 한다.At this time, the internal temperature of the first, second and third cylinders 3a, 3b and 3c of the cylinder 3 is 90-110 ° C. for the first cylinder 3a and 170-190 for the second cylinder 3b. ° C, the third cylinder (3c) is maintained at a temperature of 230-250 ° C to achieve a well formed in the first cylinder (3a), the α- (working) in the second cylinder (3b), the third cylinder In (3c), grain flour and saturated steam are compressed.

따라서, 제1실린더(3a)로 공급된 곡류가루는 13%의 자체수분과 6-10% 보충공급된 물에 의하여 익기전의 상태로 되도록 유지하면서 호정이 형성되게 한다.Therefore, the grain powder supplied to the first cylinder 3a allows the lake to be formed while maintaining the state before ripening by 13% of self moisture and 6-10% of supplemented water.

즉, 곡류가루는 수분과 혼합된 상태에서 열을 받아 수분이 기화현상을 일으켜 수증기로 변하므로써 고열의 수증기에 의하여 곡류가루가 고르게 점차적으로 익기 시작하고, 또한 스크류우(4)에 의하여 제1실린더(3a)에서 제2실린더(3b)로 이송하게 된다.That is, the grain powder is heated in the state mixed with water, the moisture is evaporated to change into water vapor, so that the grain powder gradually starts to ripen evenly by the steam of high heat, and also the first cylinder by the screw 4 In (3a) it is transferred to the second cylinder (3b).

제2실린더(3b)로 이송된 곡류가루는 제2히터자켓(5b)에 의하여 내부온도가 170-190℃로 유지되어 있어 고열이 호정상태의 곡류가루를 더욱 가열시키게되고, 그 열작용에 의하여 압축열이 집적되어 곡류가루의 온도가 170-190℃로 되면 전분이 호화상태(GELATINIZATION)로 되어 고체와 액체의 중간물질로 변화하게 된다.The grain powder conveyed to the second cylinder 3b has an internal temperature of 170-190 ° C. by the second heater jacket 5b, so that the high temperature heats the grain powder in a stable state and is compressed by the heat action. When heat accumulates and the grain temperature reaches 170-190 ° C, the starch becomes GELATINIZATION and changes into an intermediate between solid and liquid.

이는 곡류가루가 스크류우(4)에 의하여 점차적으로 이송되는 과정에서 자연스럽게 형성된다.This is naturally formed in the course of the grain powder is gradually transferred by the screw (4).

상기와 같이 고체와 액체의 중간물질로 변화된 호화물은 스크류우(4)의 계속적인 회전에 의하여 제3실린더(3c)로 이송되며, 제3실린더(3c)로 이송되는 과정에서 제3히터자켓(5c)의 230-250℃의 온도에 의하여 점차적으로 호화물이 가열압축하게 된다.As described above, the changed cargo is converted into the intermediate material between the solid and the liquid and is transferred to the third cylinder 3c by the continuous rotation of the screw 4, and the third heater jacket in the process of being transferred to the third cylinder 3c. By the temperature of 230-250 degreeC of (5c), a hobide gradually heat-compresses.

따라서 호화물은 헤드(6)의 집적원홈(10)으로 이동할때까지 가열압축되어 집적원홈(10)에 도달하게되면 집적원홈(10)이 실린더(3)내부보다 공간이 갑자기 확장되므로 호화물은 갑자기 팽창하게 된다.Therefore, when the cargo is heated and compressed until it reaches the integration groove 10 of the head 6 and reaches the integration groove 10, the space is suddenly expanded than the interior of the cylinder 3 so that the cargo is suddenly expanded. Sudden expansion

팽창된 호화물은 헤드(6)의 다단식 노즐구멍(11)을 통해 대기중으로 순간적으로 방출되게 폭발하면서 사출성형되는 것이다.The expanded fodder is injection molded by exploding into the atmosphere instantaneously through the multi-stage nozzle hole 11 of the head 6.

이때, 노즐구멍(11)은 다단식으로 형성되어 있어 집적원홈(10)에서 팽창되어 있던 호화물이 노즐구멍(11)의 다단식 형상에 의하여 체적이 점차적으로 감소하게 되므로, 점차적으로 감소되어 압축된 호화물은 대기중으로 방출할때 빠른속도로 방출됨과 동시에 폭발하여 분상질로 성형이 되는 것이다.At this time, the nozzle hole 11 is formed in a multi-stage type, so that the expanded cargo in the integrated circle groove 10 gradually decreases in volume due to the multi-stage shape of the nozzle hole 11, so that the arc is gradually reduced and compressed. When a cargo is released into the atmosphere, it is released at a high speed and explodes to form a powder.

상술한 분상질은 스크류우(4)가 계속적으로 회전하기 때문에 연속적으로 폭발성형되므로 곡류의 분상질이 가래떡과 같이 길게 연속적으로 성형되는 것이다.Since the above-described powdery powder is continuously exploded because the screw 4 is continuously rotated, powdery powdery powder is continuously formed like a rice cake.

또한, 헤드(6)에서 방출되기 전에는 곡류가루가 호화물인 상태에서 방출된 후에는 분상질인 고체상태로 변하고, 노즐구멍(11)을 통해 함께 동시에 방출된 고압의 수증기는 대기중으로 방출됨과 동시에 순간적으로 사라지게 된다.In addition, before being discharged from the head 6, after the grain powder is discharged in the form of a hobide, it is changed into a powdery solid state, and the high pressure water vapor simultaneously released through the nozzle hole 11 is released into the atmosphere. It disappears momentarily.

따라서, 헨드(6)에서 계속적으로 방출성형되는 곡류의 분상질을 분쇄장치로 유도시켜 분쇄하므로써 팽화곡류가루를 만드는 것이다.Therefore, the pulverized grain powder is made by pulverizing the pulverized granules of the grains continuously discharged from the hand 6 by pulverization.

본 발명의 팽화 곡류가루는 일반 곡류가루에 비하여 월등히 개선된 분상질 가루로써 호화도가 높아 물을 넣으면 쉽게 점착하여 품질좋은 각종 가공식품을 개발할 수 있는 것이다.Puffed grain flour of the present invention is a powdery powder that is significantly improved as compared to general grain flour, and it is easy to develop various processed foods with high quality by easily adding water with high degree of luxury.

본 발명의 팽화 곡물가루는 다음과 같은 특성이 있다.Puffed grain powder of the present invention has the following characteristics.

첫째, 팽화 곡류가루는 호화분(湖化粉)이어서 점착성이 강해 면대를 쉽게 성형할 수 있으므로 국수, 송편, 만두등의 껍질을 만들 수 있다.First, the expanded grain powder is a luxury powder (호화 化 粉), which is strong in adhesiveness, and can easily form a cotton pad, thereby making shells for noodles, songpyeon, and dumplings.

둘째, 팽화 곡류가루는 분상질이므로 각종 가공식품의 재료로 하면 제조된 가공식품의 촉감을 부드럽게한다.Secondly, the expanded grain flour is powdery, so when used as a material for various processed foods, the processed food is softened.

셋째, 팽화 곡류가루는 다공질(多孔質)이므로 흡습성이 양호하다.Third, the expanded grain powder is porous, so the hygroscopicity is good.

넷째, 팽화 곡류가루는 제조할때 영양보강성분(예, 분유, 유지 또는 대두 단백질등)을 첨가하여도 제조할 수 있어 영양성을 강화할 수 있으므로 영양강화 곡류 가공식품을 제조할수 있다.Fourth, puffed grain powder can be prepared by adding nutritional supplements (eg, powdered milk, milk fat, soybean protein, etc.) at the time of manufacture, thus enhancing nutritional properties, thereby preparing processed foods.

이하 본 발명의 실시예를 설명한다.Hereinafter, embodiments of the present invention will be described.

실시예 1Example 1

곡류가루의 원료를 쌀가루로 채택하여 팽화 쌀가루를 만드는 방법은 다음과 같다.Here's how to make puffed rice flour by adopting raw grains as rice flour.

호퍼내에 쌀가루가 30메쉬에서 통과율이 100%가 되도록 분쇄한것을 저장하고, 그 쌀가루(자체수분 13%)에 물을 쌀가루량의 약 8%정도 혼합시켜 쌀가루에 수분이 골고루 흡습되도록 하였다.In the hopper, the rice powder was pulverized so that the passage rate was 100% at 30 mesh, and water was mixed with the rice powder (13% of its own moisture) by about 8% of the amount of rice powder to absorb moisture evenly in the rice powder.

이때, 제1,2,3실린더 내의 온도를 제1실린더에서는 100℃, 제2실린더에서는 180℃, 제3실린더에서는 240℃의 온도가 되도록 제1,2,3히터자켓을 작동시킨다.At this time, the first, second, and third heater jackets are operated such that the temperature in the first, second, and third cylinders is a temperature of 100 ° C. in the first cylinder, 180 ° C. in the second cylinder, and 240 ° C. in the third cylinder.

그러므로, 스크류우의 회전에 의하여 쌀가루가 제1실린더내로 자연공급되어 제2실린더로 이송되게하고, 이때 제1실린더에서 10O℃의 온도를 유지하므로써 쌀가루와 수분이 가열되어 쉽게 호정(익는 상태)이 되게 하였으며, 그후 제2실린더로 이송시켜 180℃로 가열하여 α-화(호화 : 죽상태)되게 하였다.Therefore, rice powder is naturally supplied into the first cylinder by the rotation of the screw and is transferred to the second cylinder. At this time, the rice powder and water are heated to maintain a temperature of 10 ° C. in the first cylinder, so that the rice cake is easily fixed. Then, it was transferred to a second cylinder and heated to 180 ° C. to be α-enriched.

그후 제3실린더로 계속 이송시켜 240℃의 온도로 가열하여 쌀가루와 포화증기가 압축되어 헤드를 통해 자연적으로 가압방출하므로써 쌀분상질을 사출성형하였다.After that, it was continuously transferred to a third cylinder, heated to a temperature of 240 ° C., and rice flour and saturated steam were compressed to naturally pressurize and discharge the rice powder to injection molding the powder.

이때 쌀분상질을 가래떡과 같이 연속적으로 사출성형되므로 이를 분쇄장치로 유도시켜 분쇄하여 팽화 쌀가루를 만들었다.At this time, since the rice powder is continuously injection-molded like sputum rice cake, it is pulverized by inducing it to a pulverizing device to make expanded rice flour.

시험예 1Test Example 1

이와같이 제조된 팽화 쌀가루를 농업진흥청 농업기술연구소에서 밀가루, 보통쌀가루와 비교한 결과 표 1과 같은 시험결과가 나왔다.Compared with the flour and ordinary rice flour in the puffed rice flour prepared in this way at the Agricultural Technology Research Institute of Agriculture Promotion Agency, the test results are shown in Table 1.

[표 1]TABLE 1

Figure kpo00002
Figure kpo00002

상술한 시험결과, 예컨데 보통 쌀가루는 12메쉬통과분이 7-10%밖에 되지 않고, 밀가루는 40%이나 본발명의 팽화 쌀가루는 35%로 되어 밀가루와 거의 비슷한 메쉬를 가진 가루로 만들수가 있음을 입증되었고, 또한 100-200메쉬 사이에서는 팽화 쌀가루가 보통 쌀가루보다는 월등히 우수한 품질로 인정받았다.As a result of the above test, for example, the average rice flour is only 7-10% of 12 mesh, and the flour is 40%, but the expanded rice flour of the present invention is 35%, which can be made into flour with a mesh almost similar to the flour. Also, between 100 and 200 mesh, expanded rice flour was recognized as being of superior quality than ordinary rice flour.

그리고, 호화도에서 팽화 쌀가루는 98%의 미세한 분상질로 나타났음이 입증되었고, 보통 쌀가루는 본 발명의 팽화 쌀가루보다 현저히 낮은 수치로 나타났다.And, it was proved that the expanded rice flour was 98% fine powder in gelatinization degree, and the normal rice flour was significantly lower than the expanded rice flour of the present invention.

즉 사진(1)은 생쌀가루의 입자구조이며, 사진(2)는 팽화 쌀가루이 입자구조로써 전자 주사 현미경으로 3,000배 확대한 것이다.That is, the photograph (1) is a grain structure of raw rice flour, and the photograph (2) is a expanded rice flour grain structure, which is enlarged 3,000 times by an electron scanning microscope.

다음은 보통 쌀가루와 팽화 쌀가루로 빵을 만들었을때의 차이점을 나타낸 설명이다.The following is a description of the difference between making bread from ordinary rice flour and expanded rice flour.

종래의 쌀빵은 로라제분기 또는 디스크제분기등으로 제조된 쌀가루를 20-30% 첨가하였으나 빵의 품질이 다음과 같이 좋지 못해 상품화 되지 못하였다.Conventional rice bread was added 20-30% of the rice flour prepared by Laura flour mill or disc mill, but the quality of bread was not as good as the commercial was not.

첫째, 쌀가루가 거칠어 20%만 첨가하여도 빵이 부드럽지 못하고 씹히는 맛이 까칠하여 불쾌감을 주었다.First, even when only 20% of the rice flour is added, the bread is not soft and the taste is chewy and gives unpleasant feelings.

둘째, 쌀가루를 20%만 섞어도 제조된 빵이 쉽게 굳어(노화현상)2일만 보관하여도 오래된 빵처럼 보여 상품성이 낮았다.Second, even if only 20% of the rice flour was mixed, the prepared bread was easily hardened (aging).

셋째, 쌀가루에 점착성이 적어 빵이 신연성이 낮았다.(제4도의 (c)참조)Third, the bread was less stretchy due to less stickiness to rice flour (see (c) in Figure 4).

이에 비해 본 발명의 팽화 쌀가루의 장점은 다음과 같다.In contrast, the advantages of the expanded rice flour of the present invention are as follows.

첫째, 팽화 쌀가루는 입도가 미세하고 분상질이어서 흡습성이 양호하여 빵의 질감을 균일케 한다.First, the expanded rice flour is fine and powdery, so the hygroscopicity is good, so that the bread texture is uniform.

둘째, 팽화 쌀가루는 익은 가루여서 점착성이 있어 제빵중 가포보유능이 개선될뿐만 아니라 빵이 익은후에도 빵에 끈기를 부여하고 신연성을 증대시킨다.Secondly, the expanded rice flour is sticky because it is a ripe powder, which not only improves the capturing ability during baking, but also gives stickiness to the bread even after the bread is ripe and increases its flexibility.

셋째, 팽화 쌀가루는 전분입자가 분상화되어 있으므로 이러한 팽화 쌀가루는 50% 이상 첨가하여도 제4도의(b)와 같이 신연성이 양호할뿐 아니라 부드럽고 빵의 굳는 속도가 늦어져 빵의 상품가치가 높으며, 실제 쌀빵을 제조하여 물성을 조사한 결과 시험예 2 및 시험예 3과 같다.Third, because the expanded rice flour is powdered starch particles, such expanded rice flour is not only good stretchability as shown in (b) of FIG. , The actual rice bread was produced and examined as a result of Test Example 2 and Test Example 3.

일반 쌀가루, 팽화 백이분 및 팽화 현미분을 각각 30%씩 첨가하되 표준 배합비에 따라 스트레이트법으로 식빵을 제조하여 농업진흥청 농업기술연구소에서 평점을 받은결과 표 2와 같이 나타났다.General rice flour, puffed white powder and puffed brown rice powder were added 30% each, but bread was prepared by the straight method according to the standard blending ratio.

이와 같이 식빵의 제조시 일반쌀가루 또는 현미분을 30% 넣고 만들면 빵이 거칠고 쉽게 굳으며 푸슬푸슬하고 향미 및 외관이 불량하게 측정되었으며, 본 발명의 팽화 백미분 또는 현미분을 첨가한 경우에는 빵의 질이 고우며 쉽게 굳지않고 끝기가 있고 향미 및 외관이 우수하계 측정되었다.Thus, when the bread is made by adding 30% of normal rice flour or brown rice powder, the bread is rough, easily hardened, fluffy, and has a bad flavor and appearance. The swelling white powder or brown rice powder of the present invention is added. The quality is fine, not easily hardened, there is a finish, and the flavor and appearance are excellent.

실험예 3Experimental Example 3

빵의 단단함과 끈기를 측정하는 것으로 기계적으로도 구할수 있다.It can also be obtained mechanically by measuring the hardness and tenacity of bread.

즉, 봉상침공기(針孔器)로 눌러 빵에 구멍을 뚫을때 침공기에 오는 응력을 조사하면 되는 것으로 제4도의(c)와 같이 단단한 빵(예, 일반 쌀가루빵)은 침공기를 약간만 눌러도 단단하므로 큰 응력이 감지되나 제4도의(b)와 같이 부드러운 빵(예, 팽화 쌀가루빵)은 이런 초기 응력이 매우 작다.In other words, it is necessary to examine the stresses coming to the invader when punching the bread by pressing it with a rod invader. As shown in (c) of FIG. 4, hard bread (for example, rice flour bread) is hard to press the invader slightly. Therefore, a large stress is sensed, but soft bread (eg, expanded rice flour bread) as shown in FIG. 4 (b) has a very small initial stress.

한편, 끈기나 신연성이 적은 빵(예, 보통 분빵)은 침공기로 뚫을때 쉽게 부스러지므로 이 응력이 누적되지 못하여 최대 응력이 매우 적으나 끈기있는 빵(예, 백미빵)은 쉽게 부서지지 않으므로 이 응력이 누적되어 최대 응력이 매우크다.On the other hand, bread with less stickiness or stretch (e.g., ordinary bread) is easily broken when it is drilled through invaders, so this stress cannot accumulate, so the maximum stress is very small, but sticky bread (e.g. white rice bread) is not easily broken. Is accumulated and the maximum stress is very large.

제4도는 쌀가루 30%첨가빵의 변형응력 조사결과로써 팽화미 첨가빵은 그 질이 제4도의(a)와 같이 밀빵과 거의 같음을 알수 있다.4 shows the strain stress of the 30% rice flour added bread, and the quality of the bulge rice added bread is almost the same as that of wheat bread as in FIG.

또한 종래의 일반 쌀가루는 점착성이 전혀 없어 면대를 만들수 없으나 일반 쌀가루에 본 발명의 팽화 쌀가루를 15-26% 첨가하면 쌀가루의 점착성이 매우 커지므로 쉽게 면대를 만들수가 있다.In addition, the conventional general rice flour can not make a cotton pad because there is no adhesive at all, but when the expanded rice flour of the present invention is added to the general rice flour 15-26%, the stickiness of the rice powder is very large, it is easy to make a cotton stand.

이러한 면대는 국수모양으로 자르면 국수가 되고 송편이나 만두피 모양으로 자르면 쌀만두 및 송편을 만들기가 매우 쉽다.These noodles are noodle-shaped when cut into noodles, and when cut into songpyeon or dumpling skins, it is very easy to make rice dumplings and songpyeon.

그리고 본 발명의 팽화 쌀가루는 분상질이므로 제조된 가공식품의 식감을 개선한다.And because the expanded rice flour of the present invention is a powdery quality improves the texture of the prepared food.

이러한 특성을 이용하여 종래의 백설기의 까칠까칠한 식감때문에 상품성이 낮았던 단점을 개선할 수 있는데 이 팽화 쌀가루를 이용하여 백설기를 만들면 표 3와 같이 오래 저장하여도 씹는 맛이 부드러운 백설기를 얻을 수가 잇다.By using these characteristics, it is possible to improve the shortcomings of low commerciality due to the rough texture of the conventional snow white. When making snow white using this expanded rice flour, it is possible to obtain a soft snow white taste even if stored for a long time as shown in Table 3.

한편 풀빵제조에는 가루에 비하여 물을 1.5배 이상 넣는데 종래의 쌀가루는 경질이며 입도가 굵어 이렇게 반죽을 하면 쌀가루가 가라앉아 풀빵을 제조할수 없으나 본 발명의 팽화 쌀가루는 호화분이므로 물에 잘풀리고 점도를 높혀 졸 안정제(Sol Stabilizer)로도 활용할 수 있어 쌀을 이용한 풀빵을 제조할 수 있다.Meanwhile, in the manufacture of full bread, water is added 1.5 times or more as compared to powder, but conventional rice flour is hard and the grain size is thick, so when the dough is soaked, the rice powder sinks, but the full bread cannot be prepared, but the expanded rice powder of the present invention is fine powder, so it loosens well and the viscosity It can also be used as a sol stabilizer (Sol Stabilizer) to make a full bread using rice.

즉, 보통 쌀가루에 팽화 쌀가루를 20-30%섞는 것인데 이러한 팽화-일반 쌀가루는 물을 2배 이상 첨가하여 반죽하여도 가라앉지 않아 풀빵류를 쉽게 만들수 있다.In other words, 20-30% of inflated rice flour is mixed with rice flour. This inflated-normal rice flour does not sink even when kneaded by adding more than two times of water, making full bread easily.

그리고, 실시예로 본 발명의 팽화 쌀가루는 다공질 호화분이어서 수프(Soup)제조에도 이용될 수 있다.In addition, as an example, the expanded rice flour of the present invention may be used in the preparation of soup because it is a porous gelatinous powder.

즉, 기존 쌀수프(미수가루)는 쌀을 찌거나 볶은후 가루로 제분한 것인데 이 가루는 다공질이 아니어서 친수성(親水性)이 매우 나빠 물에 탈때 쉽게 풀리지 않고 둥둥떠다니어 오래 저어야만 하는 단점이 있었는데 팽화 쌀가루를 20-30메쉬되게 분쇄하여 수프로 만들면 물을 부을때 거친 가루사이로 물이 들어가고 다시마 공질 가루입자에도 쉽게 확산되므로 물만 타면 젖지 않아도 풀리는 미수가루를 만들수 있다.In other words, conventional rice soup (misu-ru) is milled into powder after steaming or roasting rice. This powder is not porous, so its hydrophilicity is very bad. If you make swelled rice powder into 20-30 mesh and make it into soup, water enters between the coarse powder when you pour water, and it is easily spread to the coarse powder particles.

실시예 2Example 2

곡류가루의 원료를 보리가루로 채택하여 상술한 실시예 1공정과 동일한 방법으로 팽화 보리가루를 만들었다.Pulverized barley flour was prepared in the same manner as in Example 1 above by adopting the raw material of cereal flour as barley flour.

상기 팽화 보리가루도 팽화 쌀가루와 동일한 시험을 거친 결과 팽화 쌀가루와 같은 결과를 얻었다.The expanded barley flour was also subjected to the same test as the expanded rice flour, and the same result as the expanded rice flour was obtained.

따라서, 이에 대한 설명은 생략한다.Therefore, description thereof is omitted.

이와같이 본 발명은 팽화 곡류가루를 이용하여 기호에 알맞는 장, 죽, 인스탄트 식품등에 적용시켜 제조할 수 있는 잇점이 있다.In this way, the present invention has the advantage that it can be produced by applying to the intestines, porridge, instant food, etc. suitable for the taste using expanded grains.
