Description

  The present invention relates to a powdered food containing particles obtained by pulverizing fruit bodies and mycelia of moss and a method for producing the same.

Conventionally, moss contains physiologically active substances, dietary fiber, etc. that express antitumor activity, blood glucose regulation activity, antihyperlipidemic activity, antiallergic activity, antihypertensive activity, etc. useful for human body Various functional foods, health foods and the like using this characteristic have been proposed (for example, see Patent Documents 1 to 5).
Japanese Patent Publication No. 6-43335 JP-A-11-1438 Japanese Patent No. 3260329 JP 2001-72601 A JP 2004-123635 A

However, the above conventional techniques have the following problems.
(1) The techniques disclosed in Patent Documents 1 to 4 use powders obtained by pulverizing moss and extract extracts obtained by extracting moss. The moss contains a large amount of physiologically active substances such as polysaccharides such as β-D-glucan having high immunostimulatory ability and dietary fiber, but most of the physiologically active substances are present in the cell walls and inside the cells. Even if the powder obtained by simply pulverizing the moss is taken orally, the proportion of the physiologically active substance absorbed into the body is low due to the relatively hard cell wall, and most of it is not absorbed and discharged outside the body. However, the ingestion efficiency is low and it is difficult to increase physiological activity.
(2) When using an extract of moss, the extraction operation is complicated and lacks productivity, and the dietary fiber is not included in the extract, so that the useful components of moss cannot be used without waste. Had.
(3) In Patent Document 5, in order to facilitate the absorption of physiologically active substances such as β-D-glucan and ergosterol contained in cells, moss fruit bodies and mycelia are reduced to the size of the cell or less. Physiologically active substances pulverized into fine particles are described. By crushing moss into microparticles smaller than the size of the cell, the cell wall is destroyed and the physiologically active substance in the cell is easily absorbed into the body, but such a problem is that such microparticles are likely to aggregate and lack handleability. Had.
(4) In order to obtain effects other than physiological activity possessed by mosses, fine particles that are less than the size of moss cells and drugs or foods containing vitamins, dietary fibers, other physiologically active substances, etc., in a predetermined ratio When they are mixed together, they are likely to agglomerate or be unevenly distributed because their specific gravity and particle size are different, and it is difficult to mix and disperse uniformly at a predetermined ratio, and when each component is agglomerated or unevenly distributed Has a problem that a plurality of physiologically active substances or the like cannot be ingested at a predetermined ratio.

The present invention solves the above-mentioned conventional problems, and remarkably enhances the absorption efficiency of physiologically active substances possessed by moss into the body, antitumor activity, blood glucose control activity, antihyperlipidemic activity, antiallergic activity, antiallergic activity, Physiological activity such as hypertension activity can be remarkably enhanced, useful components of core particles can be absorbed into the body, complex synergistic action can be obtained, and aggregation of fine outer shell material particles can be prevented and handled In addition to being excellent in performance, the core particles and the outer shell particles can be uniformly dispersed at a predetermined ratio to prevent uneven distribution of each component. If a predetermined amount of powdered food is weighed and ingested, it is blended at a predetermined ratio Core particles and outer shell particles can be reliably ingested at a predetermined quantity ratio, and not only physiologically active substances such as β-D-glucan and ergosterol but also useful essential amino acids possessed by moss, abundant Without discarding any dietary fiber And to provide a powdered food which can be ingested Te.
In addition, the present invention can produce powdered foods in a dry manner, can suppress the occurrence of spoilage due to moisture, can improve the storage stability, and can use expensive moss particles without waste. Produces high-pure powdered foods with high product yield and high heat resistance due to friction and impact. An object of the present invention is to provide a method for producing a powdered food product.

In order to solve the above-described conventional problems, the powdered food and the method for producing the same according to the present invention have the following configurations.
The powdered food according to claim 1 of the present invention is an orally ingestible core material particle, and a fruit body and / or mycelium of the moss ground to a particle size smaller than the size of the moss cell. And outer shell particles fixed to the surface of the core particles.
With this configuration, the following effects can be obtained.
(1) Core particles that can be taken orally, and shells and mycelium of moss ground to a particle size smaller than the size of moss cells, and the outer shell immobilized on the surface of the core particles Therefore, when it is ingested orally before meals and reaches the intestine etc., first, a physiologically active substance such as β-D-glucan contained in the cell wall of the outer shell material particles of the moss and in the cells Absorbed. The outer shell particles are pulverized to a particle size smaller than the cell size of the moss cells and the cell wall is destroyed. Therefore, the absorption efficiency of the cell wall and the physiologically active substance in the cell is remarkably increased. Physiological activities such as activity, blood glucose regulating activity, antihyperlipidemic activity, antiallergic activity, and antihypertensive activity can be remarkably enhanced. Further, useful components of the core material particles are absorbed into the body, and an effect corresponding to the type of the core material particles is obtained.
(2) Since the fine outer shell particles are immobilized on the surface of the core particles, the fine outer shell particles are prevented from agglomerating and have excellent handling properties, and the core particles and outer shell particles Can be uniformly dispersed at a predetermined ratio and each component can be prevented from being unevenly distributed. Therefore, if a predetermined amount of powdered food is weighed and ingested, the core particles and outer shell particles mixed at a predetermined ratio are mixed. It can be reliably ingested at a predetermined ratio.
(3) Since the outer shell particles are fruit bodies and mycelium of moss ground to a particle size smaller than the cell size, not only physiologically active substances such as β-D-glucan and ergosterol but also moss All useful essential amino acids and abundant dietary fiber can be consumed without being discarded.

  Here, the core particle is not particularly limited as long as it is an orally ingestible particle. For example, herbal medicines such as plants, animals and minerals, pharmaceuticals, vitamins, plant rhizomes, berries and seeds are pulverized. The powder etc. which manufactured powder, a plant extract, and an animal extract by spray drying etc. can be used.

  The average particle diameter of the core particles is preferably 5 to 100 μm, preferably 8 to 50 μm. As the average particle size becomes smaller than 8 μm, the particle size of the outer shell material particles approaches the particle size of the outer shell material particles, and it becomes difficult to fix the outer shell material particles to the surface of the core material particles at a predetermined ratio, and the product yield of powdered food tends to decrease. As the average particle size becomes larger than 50 μm, the ratio of the volume of the core material particles to the total amount of the volume of the outer shell material particles fixed to one core material particle increases. Since the ratio of the outer shell material particles in the powdered food is relatively small, when the same amount of the powdered food is ingested, the amount of the outer shell material particles containing a large amount of the physiologically active substance tends to be reduced. In particular, when the distance is smaller than 5 μm or larger than 100 μm, these tendencies become remarkable, so that neither is preferable.

The shells that make up the outer shell particles are: Tamogitake, Hanabiratake, Yamabushitake, White Maitake, Choreimaitake, Tombaitake, etc., Agaricus mushroom, Meshimaritake, Shiitake, Matsutake, Oystertake, Himematsutake, Mannentake , Kawaratake, birch, bamboo jellyfish, bamboo shimeji mushroom, purple mushroom, enokitake mushroom, chaga and the like.
As fruit bodies and mycelium of mosses, fruit bodies that grow naturally in Yamano, etc., fruit bodies obtained by cultivation, dried mycelium contained in a culture solution obtained by artificial culture, etc. are used. .

As a device for crushing fruit bodies and mycelium of moss, a high-speed rotary crusher such as a centrifugal classification mill using a high-speed rotating impact plate, a flow tube type that stirs a medium such as beads or balls in a cylindrical container A medium agitation type pulverizer such as an air flow suction type in which particles are pulverized by being pulverized in a jet current, a nozzle-passing type, a collision type, a composite type, etc., and a milling type such as a stone mortar type can be used.
As a pretreatment for pulverization, it is preferable to dry the fruit bodies and mycelium of moss so that the water content is 0 to 15%. As a result, the fine powder after pulverization can be prevented from agglomerating, and it is difficult to cause spoilage due to moisture, thus allowing long-term storage.
In addition, as the water content becomes higher than 15%, the fine powder after pulverization tends to re-agglomerate and solidify, lacks handling properties, and tends to rot and lack storage stability, which is not preferable. As it approaches 0% dryness, there is a tendency that aggregation and spoilage are less likely to occur, and handling and storage can be improved. In particular, an absolutely dry state with a moisture content of 0% is most preferable.

The average particle diameter of the outer shell material particles is preferably 0.5 to 5 μm, preferably 1 to 3 μm. By setting the average particle size to 1 to 3 μm, almost 100% of the outer shell material particles become fine particles smaller than the cell wall interval (cell size) and the cell wall is destroyed. The absorption efficiency of physiologically active substances such as D-glucan into the body can be increased, and the pulverization efficiency can be increased.
As the average particle size becomes larger than 3 μm, the proportion of particles having a particle size larger than the cell size increases, and the proportion of outer shell material particles that cannot be absorbed by the physiologically active substance increases and increases in the body. The absorption efficiency tends to decrease, and as the average particle size becomes smaller than 1 μm, aggregation tends to occur and it tends to be difficult to uniformly fix to the surface of the core material particles. In particular, when the average particle size is larger than 5 μm or smaller than 0.5 μm, these tendencies become remarkable, so that neither is preferable.

  Means for immobilizing the outer shell material particles on the surface of the core material particles include means for using a stirring and mixing device having a stirring blade, means for using a centrifugal rotating ball mill, and the core material particles and the outer shell material particles by jet flow. Means for squirting and fixing, means for causing core material particles and outer shell material particles to be caught in and collided with each other in a jet stream, and the like can be used.

  As a weight ratio of the outer shell material particles fixed to the core material particles, 10 to 90 parts by weight are preferably used with respect to 10 parts by weight of the core material particles. As the outer shell material particles become less than 10 parts by weight with respect to 10 parts by weight of the core material particles, the content of the physiologically active substances such as moss in the powdered food decreases, and the intake efficiency tends to decrease. As the number of core particles increases, it is difficult to achieve this ratio unless the particle diameter of the core material particles approaches the particle diameter of the outer shell material particles. Therefore, the surface area of one core material particle decreases, and the outer shell material particles are fixed. Since the tendency which becomes difficult and the product yield tends to decline is observed, neither is preferable.

The powdered food of the present invention can be combined with various optional components to make a food composition within a range that does not impair the effects of the present invention according to various uses.
The food composition can be prepared in various forms usually used as health foods, for example, powders, granules, tablets, capsules, and the like using conventionally known techniques. Optional ingredients include one or more generally accepted inorganic or organic vehicles, carriers, excipients, disintegrants, binders, lubricants, preservatives, stabilizers, sweeteners, fragrances, colorings. An agent etc. can be mentioned.
Specifically, together with powdered foods, binders such as corn starch and gelatin, excipients such as calcium carbonate and microcrystalline cellulose, disintegrants such as starch and sodium carboxymethylcellulose, lubricants such as talc, lactose, salt A powder, tablet, granule, tablet, or capsule can be prepared by dispensing a sweetener such as sugar.
In addition, the powdered food of the present invention can be blended into various foods together with optional components usually used in foods. Examples of such food compositions include confectionery such as crackers, cakes, cookies, and jelly, staple foods such as bread, and seasonings.

The invention according to claim 2 of the present invention is the powder food according to claim 1, wherein the core particles are (a) plant flower, bark, stem, rhizome, tuber, root, leaf, fruit. , Pulverized particles obtained by pulverizing any one or more plant materials of seeds, (b) brewed dry particles obtained by drying the brewing liquid brewed with the plant materials, and (c) the vegetable material or animal material as a solvent. It is the structure which is any 1 or more types of the extraction dry particle | grains which extracted and dried the extract.
With this configuration, in addition to the operation obtained in the first aspect, the following operation can be obtained.
(1) Enhancing various physiological activities such as anti-inflammatory, anti-allergic, and anti-stress effects that cannot be obtained from moss using active ingredients such as physiologically active substances possessed by natural plant materials and animal materials. Can do.

Here, the plant material includes flowers such as roses, wild peaches, and tosan flowers; stems of flowers such as cauliflower and broccoli; stems of algae such as mekabu, arame, hondawala, akamoku, hijiki, mozuku, and chlorella; buttons, licorice Roots such as honoki, Salacia reticulata, Salacia prinoides, Salacia oblonga, Kotarahim, etc .; Rhizome such as ginger, shukusha, turmeric; Tubers such as ginseng, sweet potato, potato; Ginkgo biloba, tea, wheat , Guava, olives, aloe, perilla leaves; cereals such as rice, wheat, buckwheat, corn, citrus fruits such as oranges, oranges, daidai, lemon, gardenia, blueberries, raspberries, rose hips, acerola, perilla, pineapple, apples , Prunes, grapes, plums, plums, bitter melons, red beans, soybeans Fruit such as legumes; sesame, sunflower, pumpkin, seeds such as milk thistle (Silybum marianum), is used.
Examples of animal materials include crustacean shells, shark fins, and oils such as cod liver oil, shark liver oil, and squid liver oil collected from the livers of marine animals.

As the pulverized particles, plant material is jetted into a high-speed rotary pulverizer such as a centrifugal classification mill, a medium agitating pulverizer such as a flow tube type, an air current suction type, a nozzle passing type, a collision type, or a composite type. What grind | pulverized using grinders, such as a grinder and a stone mill type, can be used. Steps, irregularities, holes and the like are formed on the surface of the pulverized particles, so that the outer shell material particles can be fitted and fixed to these.
As the brewed dry particles, those obtained by spray-drying mash or vinegar fermented using plant materials such as cereals and fruits as the main raw material can be used.
Extracted and dried particles are made by bringing plant material or animal material into contact with a solvent such as ethanol, water, hexane, supercritical carbon dioxide, etc., transferring soluble components to the solvent, and distilling off the solvent from the resulting solution. The resulting particles are used.
Among these, brewed dried particles and extracted dried particles are preferably used. This is because active ingredients such as physiologically active substances and amino acids are concentrated and easily absorbed by the body, so that the active ingredients can be efficiently ingested. In particular, extracted and dried particles are preferably used. Since the soluble component is concentrated, the particles have some plasticity and the particles are not easily broken. Therefore, the core particles are not easily broken by the impact of the outer shell particles fixed by collision or the like, and the solvent is distilled off. This is because holes, irregularities, and the like are formed on the surface as traces, so that the outer shell material particles can be easily fixed to the irregularities, holes, etc. on the surface, and the product yield of the powdered food can be increased.

The invention according to claim 3 of the present invention is the powdered food according to claim 1 or 2, wherein the moss is a bamboo shoot.
With this configuration, in addition to the operation obtained in the first or second aspect, the following operation can be obtained.
(1) Since Tamogitake has a high content of β-D-glucan, it can enhance the immune activity and enhance the natural healing power.
(2) Since Tamogitake is rich in dietary fiber, it can affect the metabolism of fat and carbohydrates, improve the intestinal environment and enhance the prevention of lifestyle-related diseases.
(3) Since Tamogitake contains abundant essential amino acids, the effect of supplementing amino acids can be obtained, nutritional value can be improved, and metabolism can be increased.

The invention according to claim 4 of the present invention is the powdered food according to any one of claims 1 to 3, wherein the core particle is a saccharide-degrading enzyme activity inhibitor. ing.
According to this configuration, in addition to the action obtained in any one of claims 1 to 3, the following action is obtained.
(1) Since the core particle is an inhibitor of saccharide-degrading enzyme activity, if it is ingested before meals, it inhibits the activity of saccharide-degrading enzymes such as α-glucosidase. It can suppress being decomposed. For this reason, the amount of carbohydrates absorbed from the intestinal wall can be suppressed to prevent excessive accumulation in the body as fat, and the increase in blood glucose level after meals can be suppressed, and it was not absorbed further. Since the saccharide becomes a feed of lactic acid bacteria, bifidobacteria and the like in the intestine and can enhance the intestinal regulating action, the prevention effect and diet effect of lifestyle-related diseases can be enhanced.

Here, as the saccharide-degrading enzyme activity inhibitor, for example, pharmaceuticals such as glucobay (trade name, manufactured by Bayer Yakuhin) can be used.
Also obtained by bringing bark and roots of Salacia reticulata, Salacia prinoides, Salacia oblonga, Kotarahim, etc. of the asteraceae family into contact with solvents such as ethanol, hexane, supercritical carbon dioxide, etc. Particles obtained by distilling off the solvent from the solution can be used. Specifically, Salacia purinoides of the asteraceae family is extracted with alcohol such as hot methanol or hot ethanol, the obtained alcohol extract is distributed with ethyl acetate and water, and then the water transfer part is fractionated by chromatography. A solvent obtained by distilling off the solvent by spray drying or the like can be used (for example, Salacia products manufactured by Takama System). This is obtained by extraction and fractionation from plants belonging to the family Nymphalidae, which have been used as a crude drug, so that it acts gently, has excellent safety, and has some plasticity due to the concentration of active ingredients. Since the particles are hard to break, the core particles are not easily broken by the impact that the outer shell material particles collide with the surface, etc., and the holes are formed on the surface as traces of the solvent being distilled off. The outer shell particles can be easily fixed on the surface or the holes, and the yield of the product of the powdered food can be increased.

The method for producing a powdered food according to claim 5 of the present invention includes a hollow swirl flow forming chamber, and a discharge port that is disposed in the upper part of the central portion of the swirl flow forming chamber and discharges the processed particles. , I supply nozzles arranged on the peripheral wall of the swirl flow forming chamber and introducing particles accompanied by high-pressure gas, and an injection part is disposed on the peripheral wall of the swirl flow formation chamber so as to be inclined toward the peripheral wall. A horizontal swirling flow type jet mill equipped with j jet nozzles (where i <j, i, j are natural numbers), and (a) core particles that can be taken orally; A supply step of supplying outer shell material particles made of moss fruit bodies and / or mycelium pulverized to a particle size smaller than the size of the cells from the supply nozzle into the swirl flow forming chamber; (b) The core material particles and the outer shell material particles collide with each other in the swirl flow forming chamber. The shell material particles has a fixing step of making the powdered food is immobilized, the configuration with the.
With this configuration, the following effects can be obtained.
(1) Powdered foods can be produced dry by colliding core particles and outer shell particles in the swirl flow forming chamber of the jet mill, and it is possible to suppress the occurrence of spoilage due to moisture. Can be increased.
(2) Since it is processed dry using a jet mill, moss particles do not adhere to the manufacturing equipment due to moisture, and expensive moss particles can be used without waste. The rate can be increased.
(3) Since almost no heat is generated due to friction or impact, the active ingredients of moss are not altered, and a high-quality powdered food with high nutritional value can be produced.
(4) Without using an organic binder, the outer shell particles can collide with the core particles and mechanically fix the outer shell particles on the surface of the core particles. A high-purity powdered food with few impurities can be produced.

  Here, in the jet nozzle, an injection part is disposed on the peripheral wall of the swirl flow forming chamber so as to be inclined toward the peripheral wall side, and the central axis of the injection surface of one jet nozzle disposed on the peripheral wall is set as the injection of another jet nozzle. If it is arranged toward the center axis of the surface, it is possible to prevent the eccentricity of the swirling flow, to increase the frequency of collision between particles and to suppress the wear of the swirling flow forming chamber.

As the number i of the supply nozzles and the number j of the jet nozzles arranged in the swirl flow forming chamber, 1 ≦ i ≦ 5, 5 ≦ j ≦ 15, preferably 1 ≦ i ≦ 4, 5 ≦ j ≦ 13. Is preferred. As the number j of jet nozzles is less than 5, it tends to be difficult to form a concentric swirl flow in the swirl flow forming chamber. There is a tendency for the controllability to decrease, and in particular, when the number is greater than 15, this tendency becomes remarkable and the structure becomes complicated, which is not preferable. When the number i of the supply nozzles exceeds 4, the structure tends to be complicated. In particular, when the number i exceeds 5, the tendency becomes remarkable, which is not preferable.
The supply nozzle and the jet nozzle are arranged at equal intervals on the peripheral wall of the swirl flow forming chamber. When two supply nozzles are disposed, they are disposed at positions facing the peripheral wall of the swirl flow forming chamber, and when more than two supply nozzles are disposed, they are disposed at equal intervals on the peripheral wall of the swirl flow forming chamber. The

  As the shape of the swirl flow forming chamber, various shapes such as a hollow substantially disk shape, a substantially spherical shape, a substantially conical shape, and a substantially hemispherical shape can be used according to the shape of the jet portion of the jet nozzle.

  A center pole formed in a substantially conical shape at the center of the lower surface of the swirl flow forming chamber, and an outlet disposed at an upper portion of the central portion of the swirl flow forming chamber, the apex of the center pole and the lower end surface of the outlet Is placed on the center plane in the height direction of the swirl flow forming chamber, a swirl flow is formed each time a certain amount of powdered food with the outer shell material particles immobilized on the surface of the core material particles is produced. Since it is discharged from the outlet of the chamber to the outlet, it is possible to prevent particles from staying in the swirl flow forming chamber.

  As a jet nozzle, the injection part has a slit-shaped injection port formed in a slit shape and one or more circular injection ports formed so that the center is located on a central axis passing through the central axis of the slit-shaped injection port And a slit-shaped high-pressure gas flow path communicating with the slit-shaped injection port and the circular injection port are used. Thereby, since the flow rate of the gas flow injected from the circular injection port is larger than the flow rate of the gas flow injected from the slit injection port and the energy is larger, the flat gas flow injected from the slit injection port is circular. Even if the distance from the injection section is separated by the gas flow injected from the injection port, the flat gas flow is difficult to vortex and the gas flow speed is difficult to decrease. Since an ideal swirl flow is formed, the frequency of collision between the core material particles supplied to the swirl flow forming chamber and the outer shell material particles is increased, and the outer shell material particles are brought into contact with the surface of the core material particles in a short time. It can be fixed.

As the slit-shaped injection port, those formed in a substantially rectangular shape, a substantially oval shape, a substantially bowl shape, etc., or those formed by combining them into a cross shape or a radial shape are used.
The ratio of the short side length W to the long side length L (W: L, referred to as aspect ratio) of the slit-shaped injection port is 1: 2 to 1:30, preferably 1: 5 to 1. : 22 is preferably used. As the aspect ratio becomes smaller than 1: 5, the entrainment vortex increases, the velocity distribution of the gas injected from the injection section tends to spread and the energy tends to diffuse, and as the aspect ratio becomes larger than 1:22, the energy efficiency tends to decrease. Since it is seen, it is not preferable. In particular, when the ratio is smaller than 1: 2 or larger than 1:30, these tendencies become remarkable, so that neither is preferable.

As the circular injection port, one formed in a circular shape, an elliptical shape or the like is used.
As the inner diameter of the circular injection port, 1.1 to 3 times the length W of the short side of the slit injection port is preferably used. As the inner diameter becomes smaller than 1.1 times the length W of the short side of the slit-shaped injection port, it is difficult to obtain the effect of forming the circular injection port, and the edge-shaped gas flow easily vortexes at a short distance from the injection unit. There is a tendency that the gas flow velocity tends to decrease, and as it becomes larger than 3 times, the gas flow injected from the circular injection port becomes entangled in the gas flow, the gas flow velocity decreases, and the energy loss increases. Therefore, neither is preferable. In addition, the internal diameter of the circular shaped injection port formed in elliptical shape shall mean a long diameter.
Note that the high pressure gas flow is rectified by the slit-like high pressure gas flow path, and the flux is hardly disturbed by the inertial force, so that high energy can be maintained.

  In addition, the jet nozzle may be replaced with a circular injection port, and may be provided with grooves formed at predetermined intervals in at least a plurality of locations on the long side of the slit-shaped injection port. As a result, the gas flow ejected from the slit-shaped injection port is unlikely to be disturbed and the gas flow speed is difficult to decrease, so that the eccentricity of the swirl flow is less likely to occur, and a concentric ideal swirl flow is formed. The frequency with which the core material particles supplied to the flow forming chamber collide with the outer shell material particles increases, and the outer shell material particles can be immobilized on the surface of the core material particles in a short time.

Here, as the groove portion, one formed at least at a plurality of locations on the long side is used. This is because the edge-like gas flow injected from the slit-like injection port is easily disturbed on the long side, and can be prevented. In addition, it can also form in multiple places of a short side as needed. Moreover, as a groove part, what was formed over the full length of a slit-shaped high pressure gas flow path is used suitably. This is because the rectifying effect can be enhanced.
As the width W1 of the groove, one formed to be 50 to 100 μm is preferably used. As the width becomes narrower than 50 μm, there is a tendency that it is difficult to obtain the effect of preventing the turbulence in the injected gas flow, and as the width becomes wider than 100 μm, the gas flow tends to become turbulent. Therefore, neither is preferable.
As the depth d1 of the groove part (distance from the slit-shaped injection port to the bottom part of the groove part), one formed to be 50 to 100 μm is preferably used. As the depth becomes shallower than 50 μm, there is a tendency that it becomes difficult to obtain the effect of preventing the turbulence in the injected gas flow, and as the depth becomes deeper than 100 μm, the gas flow tends to be turbulent. Since both are seen, neither is preferable.
As the interval W2 between the groove portions, those formed to be not less than the width W1 of the groove portions and not more than 5 times the width W1 of the groove portions are preferably used. As the gap between the grooves becomes narrower than the width W1 of the groove, there is a tendency that it is difficult to obtain the effect of preventing the turbulence in the injected gas flow, and as the gap becomes wider than 5 times the width W1, the gas flow is reversed. Since there is a tendency that disturbance is likely to occur, neither is preferable.

The grooves are preferably formed in parallel to each other. This is because it is rectified and can maintain high energy.
In addition to forming the groove portion in the slit-shaped injection port, the above-described circular injection port can also be formed.

  In addition, the jet nozzle includes a slit-shaped injection port formed in a slit shape and a slit-shaped high-pressure gas channel communicating with the slit-shaped injection port. A thing provided with the central axis of a jet nozzle and predetermined twist angle alpha can also be used. Thereby, in addition to the horizontal swirl flow formed in the swirl flow forming chamber, the gas flow itself ejected from the injection unit can form a swirl flow, so the core particles supplied to the swirl flow forming chamber and The frequency of collision with the outer shell material particles increases, and the outer shell material particles can be immobilized on the surface of the core material particles in a short time.

  Here, the torsion angle α is an angle formed by the edge of the slit-shaped high-pressure gas flow path and a straight line parallel to the central axis of the slit-shaped injection port passing through one point on the slit-shaped high-pressure gas flow path. As the twist angle α, a twist angle of 5 to 22.5 ° is preferably used. As the twist angle becomes smaller than 5 °, the gas flow injected from the injection section tends to be unable to form a swirling flow, and as the twist angle becomes larger than 22.5 °, the velocity of the gas flow injected from the injection portion decreases. Neither is preferred because of the tendency to

In addition, as a slit-shaped injection port, what was formed in the above-mentioned substantially rectangular shape, substantially oval shape, substantially bowl shape, etc., and what formed them in the cross shape, radial form, etc. can be used. Among them, those formed in a substantially oval shape, a substantially bowl shape, etc. in which both ends of the long side of the slit-shaped injection port are rounded, or those formed by combining them into a cross shape or a radial shape are suitable. Used. This is to prevent the occurrence of entrainment vortices at both ends of the long side of the slit-shaped injection port and to prevent the gas flow speed from being lowered. As the radius of curvature R of the end of the long side of the slit-shaped injection port formed in a substantially oval shape, a substantially bowl shape, etc., if the length of the short side in the central axis of the slit-type injection port is W, W / 2 to 5 W is preferably used. As the radius of curvature R becomes smaller than W / 2, the shape of the injection portion approaches a substantially circular shape, and the vortex increases, and the velocity of the injected gas flow tends to decrease. Since the shape approaches a substantially circular shape and the gas flow speed decreases and the swirl flow tends to be less likely to be formed, neither is preferable.
In addition, the above-mentioned circular injection port and a groove part can also be formed in a slit-shaped injection port.

  Further, the jet nozzle has a jet groove provided with a spiral groove jet port, and the spiral groove of the spiral groove jet port is formed on the inner wall surface of the gas flow path having a substantially circular cross section at regular intervals. It can also be used. Thereby, in addition to the horizontal swirl flow formed in the swirl flow forming chamber, the gas flow itself injected from the injection section can form a swirl flow, so that the core supplied to the swirl flow forming chamber can be formed. The frequency of collision between the material particles and the outer shell material particles increases, and the outer shell material particles can be immobilized on the surface of the core material particles in a short time.

Here, as the gas flow path, a gas flow path having a substantially circular shape such as a circular shape or an elliptical shape is used.
As the spiral groove, 3 to 20, preferably 3 to 17, are formed on the inner wall surface of the gas flow path. This is not preferable because the number of spiral grooves tends to be less likely to form as the number of spiral grooves decreases. When the number of swirling grooves exceeds 17 lines, the injected gas flow tends to approach turbulent flow. In particular, when the number of swirling grooves exceeds 20 lines, this tendency becomes remarkable, which is not preferable.

As the shape of the cross section of the spiral groove, those formed in a substantially rectangular shape, a substantially trapezoidal shape, a substantially semicircular shape, a substantially semicircular oval shape, a rounded substantially triangular shape, or the like are used. Among them, those having a rounded bottom such as a substantially semicircular shape, a substantially semicircular oval shape, and a rounded substantially triangular shape are preferably used. This is to prevent the generation of entrained vortices and the reduction of the gas flow speed.
The depth d2 of the spiral groove (distance from the gas flow path to the bottom of the spiral groove) is preferably r / 5 to r / 2, where r is the inner diameter of the gas flow path. As the depth d2 of the spiral groove becomes shallower than r / 5, there is a tendency that a swirl flow is less likely to be formed. As the depth becomes deeper than r / 2, a vortex is likely to occur, and the gas flow velocity tends to decrease. Therefore, neither is preferable.
The width w3 of the spiral groove is preferably πr / (3n) to πr / n using the inner diameter r of the gas flow path, where n is the number of spiral grooves. As the width w3 of the spiral groove becomes narrower than πr / (3n), there is a tendency that a swirl flow is less likely to be formed, and as it becomes wider than πr / n, a swirl tends to occur and the gas flow speed tends to decrease. In view of this, neither is preferable.

  The torsion angle γ between the spiral groove and the central axis of the gas flow path means an angle formed by the edge of the spiral groove and a straight line parallel to the central axis of the gas flow path passing through one point on the spiral groove. As the twist angle γ, 5 to 22.5 ° is preferably used. As the twist angle γ becomes smaller than 5 °, a swirl flow tends to be less likely to be formed, and as the twist angle γ becomes larger than 22.5 °, the velocity of the injected gas flow tends to decrease. .

Next, the manufacturing method of the powdered food in Embodiment 1 of this invention comprised as mentioned above is demonstrated.
First, arbitrarily selected core material particles and outer shell material particles are prepared. The outer shell material particles are obtained by pulverizing the fruit bodies and mycelium of the moss to a particle size smaller than the size of the cells of the moss. Prior to pulverization, the fruit body can be roughly cut into a size of 1 to 20 mm in a rough cutting step, if necessary. Rough cutting is performed by various conventional mills such as a cutter mill, a hammer mill, and a pin mill, and a crusher such as a high-speed mixer.
Next, if necessary, the roughly cut potatoes are dried until the water content becomes 0 to 15%. This is to prevent the fine powder after pulverization from aggregating. In addition, you may perform drying before a rough cutting process.
Next, in the fine pulverization step, the fruit bodies and mycelia are finely pulverized until the average particle size becomes 0.5 to 5 μm, more preferably 1 to 3 μm. When a jet mill, which will be described later, is used in the description of the process for producing a powdered food, it is desirable that it can be pulverized to a particle size smaller than the cell size in a short time.

Next, using a jet mill, core material particles and outer shell material particles are collided in a swirling flow, and the outer shell material particles are fixed to the surface of the core material particles to produce a powdered food.

A center pole having an upper portion formed in a substantially conical shape, 19 is an outlet formed coaxially with the center pole 18 and detachably attached to the top liner 16, and 20 is continuously provided at the upper center of the swirl flow forming chamber 11. The discharge port through which the particles pulverized in the swirl flow forming chamber 11 are discharged, 21 is a high-pressure gas header to which high-pressure gas such as dry high-pressure air or inert gas is supplied, and 21a is a jet nozzle from the high-pressure gas header 21 12 is a high-pressure gas pipe for supplying high-pressure gas to 12, and 21 b is a high-pressure gas pipe for supplying high-pressure gas from the high-pressure gas header 21 to the supply nozzle 13. 22 pressure regulating valve, 22a for adjusting the pressure of the high pressure gas header 21 is the flow rate adjusting valve for adjusting the flow rate of the high-pressure gas flowing through the high-pressure gas pipe 21b.

3, 4 (a), and 4 (b), 12 is a jet nozzle, 12 a is an ejection surface of the jet nozzle 12, and 12 b is formed in a substantially cylindrical shape on the base side of the jet nozzle 12, from the high-pressure gas header 21. A high-pressure gas passage through which the high-pressure gas to be supplied passes, 12b ′ is a slit-like high-pressure gas passage formed in a substantially slit shape connected to the high-pressure gas passage 12b, and 12c is opened at the injection surface 12a and is a high-pressure gas The injection part 12d in which the gas flow which passed the flow path 12b and the slit-shaped high pressure gas flow path 12b 'injects, and the ratio (aspect ratio) of the length W of the short side to the length L of the long side is W: L = 1 to 2 to 1:30, the slit-shaped injection port of the injection portion 12c formed in a substantially rectangular shape, 12e is the central axis of the slit-shaped injection port 12d, and 12f is the long side passing through the central axis 12e of the slit-shaped injection port 12d. A central axis parallel to the direction, 12g is a circular injection port formed so that the center is located on the central axis 12f.
As shown in FIG. 3, the jet nozzle 12 includes a jet nozzle 12 or a supply nozzle 13 in which the central axis 12e of one jet nozzle 12 is separated by two in the rotational direction of the swirl flow (counterclockwise in this embodiment). The swirl flow forming chamber 11 is disposed so as to face the central axis.
Here, in Embodiment 1, the inner diameter of the circular injection port 12g is formed to be 1.1 to 3 times the length W of the short side of the slit-shaped injection port 12d.

The manufacturing method of the powdered food using the jet mill comprised as mentioned above is demonstrated.
When the flow rate adjustment valve 22a is fully opened and the pressure adjustment valve 22 is opened, the high pressure gas is supplied from the high pressure gas pipes 21a and 21b to the push nozzle 13c of the jet nozzle 12 and the supply nozzle 13 at the same pressure. When the outer shell material particles 3 and the core material particles 2 dried so as to have a moisture content of 0 to 15% are mixed at an arbitrary ratio and supplied from the particle introduction port 13d, a high-pressure jet flow injected from the pushing nozzle 13c It is mixed with air in the solid-gas mixing chamber 13b and supplied from the venturi nozzle 13a to the swirl flow forming chamber 11 (the supply step).
A swirling flow is generated in the swirling flow forming chamber 11 by the high-pressure gas flow ejected from the jet nozzle 12, and a particle collision zone is formed on the ring liner 15 side of the swirling flow forming chamber 11 (the swirling flow forming step). In the particle collision zone, the edge-shaped high-pressure gas flow ejected by the jet nozzle 12 is blown into the swirl flow while maintaining a high speed, and the core particles 2 and the outer shell material particles 3 that circulate in the swirl flow are disturbed to collide with each other. Occurs frequently and the outer shell material particles 3 are collided and fixed to the core material particles 2, and at least a part of the surface of the core material particles 2 is coated and composited with the outer shell material particles 3, whereby the powder food 1 is produced. (The immobilization process).
When a certain amount of the powdered food 1 is produced, the powdered food 1 is discharged from the outlet 19 arranged in the swirl flow forming chamber 11 through the discharge port 20 (the discharge step).
After the swirl flow is formed in the swirl flow forming step, the flow rate of the high pressure jet flow ejected from the pushing nozzle 13c of the supply nozzle 13 by reducing the opening of the flow rate adjusting valve 22a is ejected from the jet nozzle 12. The flow rate can be reduced to about 1/10 to 1/4. In the swirling flow forming chamber 11, a concentric swirling flow is formed while the high-pressure gas flow is maintained at high speed, and the particles collide efficiently in the swirling flow to produce a powdered food 1, and the functional powdered powder 1 is discharged from the outlet. Therefore, even if the flow rate of the high-pressure gas ejected from the jet nozzle 12 is small, the particles are sucked into the swirl flow forming chamber 11 from the supply nozzle 13 (the flow rate adjusting step).

Next, a modified example of the jet nozzle will be described with reference to the drawings. FIG. 5 is a front view of a jet nozzle showing a modification of the slit-shaped injection port and the circular injection port of the jet nozzle, and FIG. 6 is a front view of the jet nozzle showing a modification of the slit-shaped injection port of the jet nozzle. .
FIG. 5A shows an example in which two circular injection ports 12g are formed at both ends of the long side of the slit-shaped injection port 12d, and FIG. 5B shows a circular injection port 12g having a slit-shaped injection port 12d. FIG. 5C shows an example in which two circular injection ports 12g are formed at locations excluding both ends of the long side of the slit-shaped injection port 12d. is there.
As described above, the circular injection port 12g can be formed at a plurality of locations as long as the center is formed on the central axis 12f, and the size and number of the inner diameters of the circular injection ports are formed. By changing the location, the aspect ratio of the slit-shaped injection port, etc., a high-pressure gas flow suitable for combining various core material particles 2 and outer shell material particles 3 can be injected. For this reason, a swirl flow with less eccentricity can be formed, the collision frequency between the core material particles 2 and the outer shell material particles 3 can be increased, and the fixed composite can be performed in a short time.

In FIG. 6, 30 is a jet nozzle in which a slit-shaped injection port 12d is formed, and 31 is a slit-shaped injection substantially orthogonal to the slit-shaped injection port 12c over the entire length of the slit-shaped high-pressure gas flow path 12b 'of the jet nozzle 30. It is a groove portion formed substantially in parallel with a predetermined interval W2 on both sides of the long side of the mouth 12d.
Here, the width W1 of the groove portion 31 is formed to be 50 to 100 μm, the depth d1 is formed to 50 to 100 μm, and the interval W2 is formed to be five times W1 to W1. Thereby, it is possible to prevent the jetted gas flow from being disturbed and to prevent the gas flow speed from being lowered. For this reason, a swirl flow with less eccentricity can be formed, the collision frequency between the core material particles 2 and the outer shell material particles 3 can be increased, and the fixed composite can be performed in a short time.

As described above, according to the method for producing a powdered food according to Embodiment 1 of the present invention, the following operation is obtained.
(1) In the swirl flow forming chamber 11 of the jet mill 10, the core material particles 2 and the outer shell material particles 3 can collide with each other to produce the powdered food 1 in a dry manner, and the occurrence of spoilage due to moisture is suppressed. Can improve the storage stability.
(2) Since dry processing is performed using the jet mill 10, moss particles and the like are not attached to the manufacturing apparatus due to moisture, and expensive moss particles can be used without waste. The yield can be increased.
(3) Since almost no heat is generated due to friction or impact, the active ingredients of the moss are not altered, and a high-quality powdered food 1 with high nutritional value can be produced.
(4) Without using an organic binder or the like, the outer shell material particles 3 can collide with the core material particles 2 to mechanically fix the outer shell material particles 3 on the surface of the core material particles 2 to be combined. Therefore, the powder food 1 with high purity with few impurities such as a binder can be produced.
(5) Since the injection part 12c of the jet nozzle 12 of the jet mill 10 includes the circular injection port 12g, the flow rate of the gas flow injected from the circular injection port 12g is large and the energy is large. The edge-like gas flow injected from 12d is dragged by the gas flow injected from the circular injection port 12g, and the edge-like gas flow hardly vortexes even when the distance from the injection portion 12c is increased. Therefore, the eccentricity of the swirling flow is less likely to occur, and an ideal concentric circular swirling flow can be formed in the swirling flow forming chamber 11, and the collision frequency between the core material particles 2 and the outer shell material particles 3 can be reduced. The outer shell material particles 3 can be immobilized on the surface of the core material particles 2 in a short time.
(6) Since the high-pressure gas passage 12b formed in a substantially cylindrical shape is formed on the base side of the jet nozzle 12, the high-pressure gas supplied from the high-pressure gas header 21 has a large cross-sectional area of the high-pressure gas passage 12b. It can be injected from the injection part 12c with a small pressure loss, is excellent in energy efficiency, and can produce the powdered food 1 in a short time.
(7) Since the slit injection port 12d has an aspect ratio of 1: 2 to 1:30, a gas flow with little entrainment vortex and a sharp velocity distribution and high energy efficiency can be injected from the injection unit 12c. The powdered food 1 can be manufactured efficiently.
(8) Since the slit-shaped high-pressure gas flow path 12b 'is provided, the high-pressure gas flow is rectified, the flux is not easily disturbed by the inertial force, high energy can be maintained, and stable production of the powdered food 1 is continuously performed. Can do.
(9) The jet section 12c is provided with the jet nozzle 12 provided with the circular injection port 12g in the swirl flow forming chamber 11, so that the swirl flow formed in the swirl flow formation chamber 11 is less likely to be eccentric and is concentric. Therefore, it is possible to fix the outer shell material particles 3 to the surface of the core material particles 2, which has been difficult until now, and to combine them in a short time. The amount of processing per unit time can be dramatically increased.
(10) Since a swirl flow is formed in the swirl flow forming step, a flow rate adjustment step is provided in which the flow rate of the high pressure gas injected from the supply nozzle 13 is made smaller than the flow rate of the high pressure gas injected from the jet nozzle 12. The flow rate of the gas injected from the supply nozzle 13 can be reduced, and the running cost can be reduced. (11) Since the flow rate of the gas flow supplied from the supply nozzle 13 is small, it is difficult for particles to blow back. However, it is difficult to cause pressure wear or uneven wear on the peripheral wall, and stable continuous operation can be performed.
(12) By providing the groove portions 31 formed at approximately a plurality of locations on the long side of the slit-shaped injection port 12d at a predetermined interval and in parallel, the gas flow injected from the slit-shaped injection port 12d is unlikely to be disturbed. Since the velocity of the gas flow is difficult to decrease, the eccentricity of the swirl flow is unlikely to occur and an ideal concentric swirl flow is formed. In addition to being able to perform immobilization, it can be combined in a short time, and the amount of processing per unit time can be dramatically increased.
(13) Since the outer shell material particles 3 are dried to a moisture content of 0 to 15%, the outer shell material particles 3 can be prevented from agglomerating, and the lump solidified by aggregation is dried and pulverized again. It is possible to obtain a powdered food 1 that can save labor and that does not easily spoil due to moisture and can be stored for a long period of time.

Moreover, since the powdered food in Embodiment 1 of this invention is comprised as mentioned above, the following effects | actions are acquired.
(1) Core material particles 2 that can be taken orally, and fruit bodies and mycelia of moss ground to a particle size smaller than the size of moss cells, and immobilized on the surface of the core material particles 2 The outer shell material particles 3 are provided so that when they are taken orally before reaching the intestine etc. before eating, the cell walls of the outer shell material particles of the moss and the physiological such as β-D-glucan contained in the cells first. The active substance is absorbed. The outer shell particles are pulverized to a particle size smaller than the cell size of the moss cells and the cell wall is destroyed. Therefore, the absorption efficiency of the cell wall and the physiologically active substance in the cell is remarkably increased. Physiological activities such as activity, blood glucose regulating activity, antihyperlipidemic activity, antiallergic activity, and antihypertensive activity can be remarkably enhanced. Further, useful components of the core material particles are absorbed into the body, and an effect corresponding to the type of the core material particles is obtained.
(2) Since the fine outer shell material particles 3 are immobilized on the surface of the core particle 2, the fine outer shell material particles 3 are prevented from agglomerating and excellent in handleability. Since it is possible to uniformly disperse the outer shell material particles 3 at a ratio of 10 to 90 parts by weight with respect to 10 parts by weight and prevent each component from being unevenly distributed, if a predetermined amount of the powdered food 1 is measured and taken, a predetermined ratio is obtained. The core material particles 2 and the outer shell material particles 3 blended in the above can be reliably ingested at a predetermined quantitative ratio.
(3) Since the outer shell particles 3 are moss fruit bodies and mycelium pulverized to a particle size smaller than the cell size, not only physiologically active substances such as β-D-glucan and ergosterol but also moss Can be consumed without discarding useful essential amino acids and abundant dietary fiber.
(4) Since the average particle diameter of the core material particles 2 is 5 to 100 μm, preferably 8 to 50 μm, the outer shell material particles 3 are likely to be immobilized on the surface of the core material particles 2, thereby increasing the product yield of the powdered food 1. In addition, the ratio of the outer shell material particles 3 in one powdered food 1 can be relatively increased, and the intake of the outer shell material particles 3 containing a large amount of physiologically active substance can be increased.
(5) The outer shell material particles 3 pulverized to an average particle size of 0.5 to 5 μm, preferably 1 to 3 μm, are almost 100% smaller than the cell wall interval (cell size), and the cell wall is destroyed. Therefore, the absorption efficiency into the body of physiologically active substances such as β-D-glucan contained in the cells can be increased, and the grinding efficiency can be increased.

In addition, in this Embodiment, although the jet mill used when making the core particle 2 and the outer shell material particle 3 collide and fix | immobilize among the manufacturing methods of the powder food 1 was demonstrated, In the pulverization step in which the outer shell material particles 3 are manufactured by pulverizing the substance and mycelium, the jet mill described in the present embodiment can also be used. In this case, the outer shell material particles 3 having a sharp particle size distribution can be produced in a short time.
Further, in the present embodiment, the case where the powdered food 1 is manufactured by using the jet mill 10 provided with the jet nozzle 12 and fixing the outer shell material particles 3 to the core material particles 2 has been described. The material is not limited to the mill 10 and any material that can collide the core material particles 2 and the outer shell material particles 3 in a jet stream can be used.

According to the method for producing a powdered food product in Embodiment 2 of the present invention, the following action is obtained.
(1) When the slit-shaped high-pressure gas flow channel 54 is provided with the central axis 53 of the slit-shaped injection nozzle 52 and the jet nozzle 50 having a twist angle α of 5 to 22.5 ° in the swirl flow forming chamber 11. Since the injected gas flow itself can form a swirl flow, the swirl flow of the gas flow itself injected from the jet nozzle 50 or the like collides with the swirl flow formed in the horizontal direction in the swirl flow forming chamber 11. By doing so, the particles can be collided three-dimensionally to increase the collision frequency, and the outer shell material particles 3 can be fixed to the core material particles 2 to produce the powdered food 1 in a short time. This is because the particles on the swirling flow injected from the jet nozzle have less forward rotation or reverse rotation in the traveling direction, and when the particles collide with each other in the swirling flow, the outer shell does not slip. It is presumed that the material particles 3 are easy to fit on the surface of the core particle 2.
(2) Since the radius of curvature R of the end portion of the long side of the slit-like injection port 52 is W / 2 to 5 W, where W is the length of the short side of the central axis 53 of the slit-like injection port 52. In addition, at both ends of the long side of the slit-like injection port 52, it is possible to prevent the generation of entrainment vortices and to prevent the gas flow velocity from being lowered, thereby forming a high-speed swirling flow and increasing the collision frequency between particles. It is possible to manufacture the powdered food 1 in a short time by fixing the outer shell material particles 3 to the core material particles 2.
(3) A jet nozzle 50 in which the slit-like high-pressure gas flow channel 54 is formed at a predetermined twist angle α with the central axis 53 of the slit-like injection port 52 is disposed in the swirl flow forming chamber 11, so that the swirl flow is 3 Since it can be formed dimensionally, the thickness of the swirl flow forming chamber 11 can be increased to substantially the same as the inner diameter of the peripheral wall of the swirl flow forming chamber 11. As a result, the volume can be dramatically increased without changing the inner diameter of the swirl flow forming chamber 11, so that the particles from the supply nozzle 41 can be reduced without reducing the speed of the gas flow injected from the jet nozzle 50 or the like. The supply amount can be increased according to the volume, the processing amount per hour can be increased, and the running cost can be greatly reduced.
(4) Since the jet nozzles 50 or the like or the supply nozzles 41 are arranged at 360 ° / (i + j) in turn in the direction of rotation of the swirl flow, the gas flows from the respective nozzles are combined and horizontally Since the swirling flow in the direction and the swirling vortex in the vertical direction are formed, the speed of the swirling flow swirling in the vicinity of the peripheral wall of the swirling flow forming chamber 11 can be suppressed, and the peripheral wall of the swirling flow forming chamber 11 and the ejection surface of each nozzle Thus, it is possible to reduce wear and the like, and to realize a stable continuous operation with less contamination.
(5) Since a plurality of supply nozzles 41 are arranged in the swirl flow forming chamber 11, it is also possible to supply powders of different types from each supply nozzle 41 to produce a powdered food.
(6) Since the supply nozzle 41 has the inner wall spiral grooves 44a and 46, a gas flow that turns itself can be injected also from the supply nozzle 41, and the collision frequency of particles can be increased and the processing efficiency can be improved. Can be increased.

Next, a modified example of the jet nozzle will be described with reference to the drawings. FIG. 11 is a schematic view showing a modified example of the slit-shaped injection port of the jet nozzle.
11A and 11B, reference numeral 55 denotes a slit portion formed in a substantially oval shape or the like.
FIG. 11A is an example in which three slit portions 55 are formed radially from the central axis 53 and the depression angle β of the slit portion 55 is formed to be 30 ° × 4 = 120 ° to form the slit-shaped injection port 52. 11B, four slit portions 55 are formed radially from the central axis 53, and the depression angle β of the slit portions 55 is formed to be 45 ° × 2 = 90 °, so that the slit-like injection port 52 is configured. It is an example. In addition, depending on the kind of particle | grain etc., the depression angle (beta) of the slit part 55 can also be formed in 75 degrees xp (p = 1, 2) etc.
As described above, since various shapes of the injection section can be obtained, an optimal swirling flow can be formed by selecting an optimal injection section according to the specific gravity of the particles.

Further, the twist angle γ is 5 to 22.5 °.

As described above, since the jet nozzle of the jet mill used in the method for producing a powdered food according to Embodiment 3 is configured, the following effects can be obtained.
(1) Since the jet nozzle 60 includes the spiral groove 64, the gas flow itself injected from the gas flow path 62 and the spiral groove injection port 64a can form a swirl flow with little pressure loss, and the swirl flow forming chamber. 11, the swirl flow of the gas flow injected from the jet nozzle 60 collides with the swirl flow formed in the horizontal direction in the cylinder 11, so that the particles can collide with each other three-dimensionally and the collision frequency can be increased. The powdered food 1 can be produced with high efficiency by fixing the outer shell particles 3 to the core particles 2 over time.
(2) Since the depth d2 of the spiral groove 64 is r / 5 to r / 2, the width w3 is πr / (3n) to πr / n, and the twist angle γ is 5 to 22.5 °, high speed The powder food 1 can be produced with high efficiency by increasing the collision frequency and immobilizing the outer shell material particles 3 on the core material particles 2 in a short time.

Seven jet nozzles having a twist angle α = 15 ° (that is, a combination of the jet nozzle described in the modification of the first embodiment and the jet nozzle described in the second embodiment) are arranged. The jet nozzle had a long side length L = 6 mm and a short side length W = 1 mm of the slit-shaped pulverized portion, and the inner diameter of the push nozzle of the supply nozzle was 2 mm.
