Description

A Method for Manufacturing Wholly Activated Functional Fine

Soybean Powder

Featuring High Purity, bv Drying Soybean with

Infrared Electromagnetic Waves

Technical Field

This invention relates to a method for manufacturing wholly activated functional fine soybean powder containing ingredients helpful for metabolism, featuring high purity with less than 2% moisture, 96% digestion at 100-900 mesh and good preservation, using the drying with infrared electromagnetic waves.

Background Art

In general, the soybean contains about 40% protein, 20% oil, 20% carbohydrate, ash, fiber and other substance helpful for metabolism. When powdered finely, it is carbonized by the heat of friction from crushing and, therefore, it is difficult to not only powder finely the soybean because its 15-18% moisture, protein and oil are mixed up each other during crushing, and but also produce the activated fine soybean powder due to its physical change and nutritive destruction by heat when the soybean is dried by more than 100 °C hot blast to crush the soybean with less than 2% moisture for the purpose of activating and powdering the soybean. When the hot blast is less than 100 °C, lipoxygenase, oxidized enzyme, is not inactivated so that a variety of problems can be caused, such as resulting in bad digestion, fishy smell of an aldehyde and ketone from oxidized fat, and cancer-causing materials.

For example, another method for manufacturing the wholly activated soybean powder was already patented(No. 182829). The method is designed to heat the soybean with the steam of 65 ^°C ~86°C to reduce its moisture to 9 — 11% suitable for removing hull, to heat again the hull-removed soybean with the steam of 65 °C ~85°C for 15-35 seconds to remove the fishy smell, and to crush the hull-removed soybean at 80 mesh on the first crush process (2,000RPM) after cooled to about 30 °C, when the temperature inside the crushing machine is kept at 55°C ~85^°C . Then, the first crushed soybean particle is again dried by a flow type dryer at the temperature of 55 °C ~9 0°C to have 3-5% moisture, and then crushed again at 150-900 mesh on the second crush process to obtain the wholly activated fine soybean powder with no any nutritive destruction.

If for the above invention the soybean is heated and dried by the steam of about 65^°C ~86°C to have 9-11% moisture, however, the steamed-heating & drying with moisture will last so long that the soybean's own functional substance can be destructed, due to its physical change coming from heat, and eventually that activated fine soybean powder can not be produced. Regarding the above invention, also, it will be impossible to remove the fishy smell of soybean by heating the hull-removed soybean with the steam of 65 °C ~86°C for 15-35 seconds because heating an oxidized enzyme, lipoxygenase, which causes the bad smell, for 1 minute at the temperature of 120 °C, makes the oxidized enzyme lipoxygenase inactivated. When the 80 mesh soybean powder is dried at the temperature of 55°C ~90°C to have 3-5% moisture in the above condition, therefore, the oxidized enzyme can not be activated also. Consequently, the most difficult problem of the above invention is that it is difficult to manufacture the wholly activated functional fine soybean powder with no bad smell even when the soybean is crushed by the first and second low-temperature crushing up to 150-900 mesh and, moreover, to mass-produce the powder to merchandise on the market.

Another example is the domestic patent No. 92-8853 for "Method and Device to Manufacture Soybean Powder." The invention is designed to sort and separate the soybean to put into a breeding machine where the soybean is bred at the temperature of 100^°C ~120°C for 2 minutes to remove the bad smell, for the soybean bred at 100^°C ~120°C to be dried by the hot blast of 70 °C to have 4.5-4.6 moisture, and then for the soybean dried by the above procedures to be crushed by the 1st and 2nd crushing processes to produce the fine soybean powder.

Regarding the above invention, however, the oxidized enzyme, lipoxygenase, can be effectively removed by breeding the soybean at the temperature of 100°C ~120°C for 2 minutes in the process of removing the bad smell as stated above. But the problem is that in so doing the soybean's nutrition is destructed so that the wholly activated functional fine soybean powder can not be produced.

Disclosure of the Invention

The present invention is technically contrived to develop a 3- step & multi-step soybean drying system with infrared electromagnetic waves' radiation, penetration, and resonance absorption, to produce the wholly activated functional fine soybean powder with helpful ingredients for metabolism and high purity, to inactivate lipoxygenase, an oxidized enzyme, to remove the soybean's bad smell and improve its digestive and absorptive function, to prevent its oil from being oxidized to last preservation, and finally to mass-produce the fine soybean powder.

This invention featuring such technical composition and function as stated above makes it possible to mass-produce wholly activated functional fine soybean powder featuring high purity and 96% digestion and good preservation (EVOH film-package available to store for 1 year at the normal temperature) without any bad smell, being very helpful for prevention against chronic diseases (Anti-cancer function, urination, prevention against constipation, diabetes, osteoporosis and heart disease, control of arteriosclerosis, improvement of liver function, and helpful effect for intestinal disorders), recovery diet of patients, women diet, children & aged people's health.

Also, the wholly activated functional fine soybean powder with helpful ingredients for metabolism has so excellent versatility that it can be used in making highly functional foods, including Tubu, fiber soybean milk, enzyme-resolution soy sauce, amino-acid drinks, soybean vinegar.

By making and supplying such highly functional Tubu, this invention will greatly contribute to saving material resources, preventing environment from being polluted, improving productivity, increasing the rural incomes, and enhancing national health. Brief Description of Drawings

As shown in Fig. 1, unlike the traditional hot blast drying, the present invention is devised to allow the soybean with 15-18% moisture contained in an "Infrared Circulating Dryer" to go through an infrared ceramic radiator with the moisture-removed indirect steam hot blast of 55°C ~85°C to generate infrared electromagnetic waves, to remove the hulls from the seed leaves after the dried soybean with 8-10% moisture have been cooled at the temperature of 15°C ~20^°C by infrared electromagnetic waves' radiation, penetration, and resonance absorption, and to first-crush the soybean's 2 or 4-divided seed leaves with 6-8% moisture conveniently by means of the infrared electromagnetic waves' radiation, penetration (40m/m), and resonance absorption of the infrared ceramic radiating dryer without any change from heat, as shown in Fig. 2.

By means that moisture-removed air is supplied to the above 2 or 4-divided soybean with 6-8% moisture, the activated functional fine soybean powder with 60-90 mesh is produced by the low-temperature impulsive type crushing machine(2,500ROM) keeping its inner temperature at 5^°C ~10^°C .

As shown in Fig. 3, the activated soybean powder with 60-90 mesh has been produced by the "stainless steel-made infrared radiating dryer." Then, the heat energy of 85 °C ~95°C is changed to infrared electromagnetic waves, when the molecule- activated energy of the 60-90 mesh activated soybean powder is increased in quantity by the outstanding penetration and resonance absorption and both powder catabolism and energy radiation are enhanced. As a result, it is possible to not only dry the activated soybean powder in the condition of 60-90 mesh and less than 2% moisture without any change from heat, but also remove the soybean's bad smell while inactivating the oxidized enzyme lipoxygenase and enhancing preservation.

In the process of several steps(Early, middle and end steps), the most effective drying of this invention devised to activate the soybean's nutrition and function with 15-18% moisture and dry the soybean by reducing the moisture has been achieved by means of the infrared electromagnetic waves' radiation, penetration (40m/m) and resonance absorption, in addition to inactivation of both the oxidized enzyme lipoxygenase and anti-trypsin inhibitor. By drying with less than 2% moisture, the crushing condition also is best-suited to removing the bad smell, bettering preservation and producing a high quality of fine soybean powder with less than the quality very In such conditions.

The detailed description of individual processes in connection with embodiments is summarized as follows.

1st Process (For a magnetic sorting machine to sort out) This is to put soybean with 15-18% moisture into a magnetic sorting machine to sort out every foreign matter from soybean.

2nd Process (To infrared-circulate and dry)

It is to put the foreign matter-removed soybean with 15-18% moisture into the grain storage tank(2) of the infrared circulating dryer shown in Fig. 1, to allow the blower(7) to blow the hot blast of 55°C ~85°C, and to, therefore, dry the soybean to have 8-10% moisture without any physical change from heat, through the hot blast-based resonance action within soybean, resulting from infrared electromagnetic waves' penetration, resonance, and absorption of the heat exchanger(7)'s infrared ceramic radiator (4).

3rd Process(To remove soybean's hulls from seed leaves)

This process is to divide the dried soybean with 8-10% moisture into

2-4 parts by means of a cutter and remove hulls from seed leaves divided into 2-4 parts.

4th Process (To dry with the infrared ceramic radiator) As shown in Fig. 2, electric energy with the temperature of 55^°C ~85^°C is supplied to the infrared radiator's ceramic plate(6) inside the infrared ceramic radiating dryer(5) to produce electromagnetic waves, when the soybean's seed leaves divided into 2-4 parts are fed to the grain tank(3) from the feeding hopper(l) through the basket elevator(2). Then, the soybean's divided seed leaves are allowed by the constant feeding valve (4) to go through the infrared radiator's ceramic plate(6) constantly so that the seed leaves divided into 2-4 parts are dried by infrared electromagnetic waves' radiation, penetration, and resonance absorption to have 6-8% moisture without any physical change from heat. And then, the soybean's seed leaves are dried to have 6-8% moisture while lipoxygenase, oxidized enzyme, is inactivated by electromagnetic waves' radiation and resonance action, and they are stored in the storage tank. 5th Process (To cool the soybean)

It is to cool the soybean's 2 or 4-divided seed leaves with 6-8% moisture up to 5^°C ~10°C to make the 1st crushing easy.

6th Process (To first-crush)

This process is designed for the low temperature- sensing type crusher exposed to 5^°C ~ 10^°C to crush the soybean cooled to 5°C ~ 10°C and with 6-8% moisture to 60-90 mesh at the speed of 2,500RPM and, so, the activated fine soybean powder can be produced.

7th Process (To dry with stainless steel-made infrared ceramic radiator) In this process, the activated soybean powder with 60-90 mesh is put into the stainless steel-made infrared radiating dryer(5) through the cyclone(4) to the lower stainless steel flow plate(2). Then, the heat energy of 85°C ~95°C is changed to infrared electromagnetic waves, when the molecule- activated energy of the 60-90 mesh soybean powder is activated by the remarkable penetration and resonance absorption and both powder catabolism and energy radiation are enhanced. As a result, it is possible to not only dry the activated soybean powder in the condition of 60-90 mesh and less than 2% moisture without any change from heat, but also inactivate the oxidized enzyme lipoxygenase and anti-trypsin inhibiter by means of the infrared electromagnetic wave energy's resonance and absorption action. Then, they are conveyed to the lower screw conveyor(l).

8th Process(To second-crush with the low temperature- sensing crusher) This process is to crush the above activated soybean powder with 60-90 mesh and less than 2% moisture at the temperature of 5°C ~10°C by means of the low temperature sensing crusher with the speed of 2.500RPM.

9th Process(To sort the mesh of soybean powder)

It is to adjust the sorting unit's speed to be suitable for sorting the fine soybean powder wholly activated to 100-900 mesh and to feed back the powder with unsuited mesh to the 2nd low-temperature-sensing crusher for the purpose of re- crushing.
