Description

  The present invention provides a vertical drop pulverizer for obtaining a granular mixed seasoning such as a curry leu granule or a stew pulverulent powder, and the granular mixed seasoning using the vertical drop pulverizer. The present invention relates to a manufacturing method for manufacturing.

  Conventionally, when there is a process of making raw materials into granules in order to obtain foods and pharmaceuticals, a pulverizer is often used in the process. In the pulverizer for such use, as shown in Patent Document 1, a plurality of rotary blades attached to a rotary shaft are rotated at high speed inside a cylindrical screen having a large number of small holes, and rotated. A pulverizer is shown in which the pulverized particles by impact with the blade are sized and discharged to the outside of the cylindrical screen as they pass through small holes in the cylindrical screen.

  Moreover, in patent document 2, the flake manufacturing apparatus which makes foodstuffs, such as curry and a stew solidified at normal temperature, flake-like is shown, In this flake manufacturing apparatus, the upper and lower surfaces of the cylinder open | released are shown. A disc-shaped sieve (perforated screen) is arranged inside the housing, and a stirring blade is attached to a shaft member passing through the center of the sieve from below at a position on the upper surface side of the sieve. The pin member protrudes toward the center side of the housing in the space above the stirring blade, and the pin member protruding in the radial direction of the shaft member is also provided on the upper outer periphery of the shaft member.

  And the said flake manufacturing apparatus preliminarily converts the food material (flake raw material) thrown in from the upper part of a housing into a large-sized food raw material by the rotating pin member and the fixed pin member into a suitable-sized lump. The crushing and rotating agitation blades fall and stay on the sieve and break the lump by collision with this agitation blade, push it into the sieve hole, shear it by the opening edge with a sharp section at the upper end of the sieve hole, and flake The flakes were allowed to fall below the sieve.

  By the way, when making curry dishes, solid roux has been used in the past. However, when a large lump of solid roux is put in hot water as it is and melted, there is a tendency to create a portion that does not progress evenly, resulting in lumps. It has been attempted to devise a method for making the luu granular or powdery so that it can be easily dissolved in hot water. In particular, it has been confirmed that the granular solid roux shown below can be dissolved particularly well.

  The granular solid roux described above is prepared by preparing a flake-shaped solid roux that has been cut into a thin plate in advance and a powder raw material that is mixed in advance separately from the cut solid roux. After mixing and pulverizing. The solid roux that has been cut is solid oil and fat, starch raw material, seasoning, and spices that are heated and mixed, and then cooled and solidified, and are cut into approximately 10 mm squares. It was made by mixing spices, seasonings, caramel (powder) and sweeteners, etc., prepared separately from Luo.

  The granular solid roux obtained by mixing and pulverizing the powder raw material has the powder raw material attached to the surface of each particle of the granular solid roux, and the granular solid roux with the powder raw material attached to the surface thereof. And the powder raw material that did not come to adhere to the surface is a mixed powder seasoning, and since the powder raw material is attached to the surface of the granular solid roux, Adhesion is prevented and the grindability and dispersibility are good.

  When obtaining the granular solid roux which is the above-mentioned powdery mixed seasoning, the mixture of the solid roux and powder raw material cut as described above is pulverized, but the pulverizer itself used for the pulverization is, Basically, the solid roux is pulverized by a collision with a rotating blade rotating inside a cylindrical body as shown in Patent Document 1 above.

  Specifically, this pulverizer will be described. A vertical rotating shaft that rotates by receiving a driving force on the upper end side of the shaft, a cylindrical body that is open on the lower surface into which the rotating shaft is inserted, and orthogonal to the axial direction of the rotating shaft A rotary pulverized body provided with wing-like rotary blades extending in the direction of the rotation axis at equal angles around the portion of the rotary shaft located inside the cylindrical body, and also provided in a plurality in the axial direction of the rotary shaft. A vertical drop pulverizer in which a main pulverization unit is configured, which has an electric motor as a drive source and legs for supporting the pulverization unit at a required height position.

  In the vertical drop pulverizer, the rotary blade of the rotating pulverized body is rotated by being charged into the cylindrical body from the upper side of the cylindrical body in a state where the cut solid roux and the powder raw material are mixed. The flake-shaped solid roux etc. are made granular by the collision, and the granular solid roux with the powder raw material adhering to the surface and the powder raw material not adhering to it fall down below the cylindrical body. In addition, if a small hole exists in the cylindrical body as in the cylindrical screen in Patent Document 1, the powder raw material passes through the small hole and is discharged alone. There are no small holes.

  However, when the mixture of the cut solid roux and the powder raw material is put into the vertical drop pulverizer, the mixture of the solid roux and the powder raw material has an outer periphery and a cylindrical body of the rotary pulverizer. It is easy to fall through the gap between the inner surface of the inner surface of the inner wall of the mixture, so that the degree of collision between the solid luws in the mixture and the rotary blade is reduced, and a granular solid roux larger than a desired size is formed in the mixture. There was a problem that the rate of inclusion was high.

  In the technique described in the above-mentioned Patent Document 2, a lump falling and staying on the sieve is forcibly pressed against the sieve with a stirring blade and pushed into the sieve hole, and the size of flakes falling from the sieve is determined. It will be adjusted below the size which passes the hole of a sieve. Therefore, it is considered advantageous to employ the technique shown in Patent Document 2 in pulverizing the mixture of the cut solid roux and the powder raw material to obtain a powdery mixture. .

  On the other hand, it is desirable that the granular solid roux that is desired to be obtained by pulverizing the mixture of the cut solid roux and the powder raw material has a size that does not reach 2 mm. The granular solid lure having a diameter of 2 mm or less and the powder raw material not adhering are uniformly mixed with hot water and easily dissolved. However, when the use of the technique in Patent Document 2 is assumed, if the size of the hole in the sieve is about 2 mm square, there is a problem that the sieve is likely to be clogged. In addition, there is a problem that the solid roux that has been cut is heated by friction with the stirring blade that is pushed into the hole of the sieve while rotating, the solid fat is softened, and the solid roux that has been cut is likely to stick to each other.

  In view of the above circumstances, the present invention is directed to the center of the rotary pulverized body in the course of passing through the cylindrical body, with the above mixture easily positioned between the outer periphery of the rotary pulverized body and the cylindrical body in the vertical drop pulverizer. To increase the degree of collision of the solid roux in the mixture with the rotary blade, and to reduce the degree of mixing of granular solid roux larger than the desired particle size when producing the powdered mixed seasoning With the goal.

Moreover, it is possible to mix | blend and use liquid fats and oils.

(Starch raw material)
The starch raw material is a dry raw material mainly composed of starch. Examples thereof include dry cereal powder raw materials such as wheat flour and rice flour, potato starch derived from potato, corn, cassava, corn starch, tapioca starch and the like. Furthermore, the processed starch which processed these starch raw materials is also included.

(Powder material)
The powder raw material is obtained by uniformly stirring and mixing spices, seasonings, colorants, sweeteners, and the like, which are powdered food raw materials, using, for example, a high-speed stirrer. As described above, the powder raw material used in obtaining the curry roux or stew which is easy to dissolve in hot water is not mixed in the process of producing the small solid roux, but the small solid roux and the powder raw material. In addition to partly adhering to the surface of the solid roux in the process of obtaining a mixture of the above, when the small loaf of solid roul is pulverized by the vertical drop pulverizer 1 into a granular solid roux, the granular solid It is made to adhere to the surface of the roux, and also to exist in the non-adhering state in the vicinity of the solid roux where the powder raw material adheres to the surface.

  As the above-mentioned spice in the powder raw material, a spice having a low lipase activity can be used. In addition, spices are also used to obtain the above-mentioned small lump solid roux, but when using a spice with high lipase activity as a raw material for obtaining this small lump solid roux, it is added at the time of heating and mixing. Try to deactivate.

  The above-mentioned seasoning in the powder raw material is solid at room temperature and can be mixed with small lump roux, and when cooking with hot water, if dissolved it can be used without any problem with oil solubility and water solubility, but it is not oil soluble Preferably, it contains a raw material that does not dissolve easily even when heated or does not generate viscosity. For example, salt, sugar, various extract powders and the like can be used as the seasoning.

As shown in FIG. 2, the pulverizing unit 2 of the vertical drop pulverizer 1 has a vertical rotating shaft 5 that rotates when the driving force from the driving source 3 is transmitted to the upper end side of the shaft, and the rotating shaft 5. Is inserted into the cylindrical body 6 having an open bottom surface, and a rotary pulverized body 7 that is provided in a portion of the rotary shaft 5 located inside the cylindrical body 6 and rotates by the rotation of the rotary shaft 5.

(Rotating pulverized body)
In the pulverizing unit 2, the rotary pulverized body 7 is provided in two stages, upper and lower, through a space 8 having only the rotary shaft 5 in the axial direction of the rotary shaft 5. Each of the lower rotary pulverized bodies 7 is formed by arranging a plurality of rotary blades 9 that project in a direction perpendicular to the axial direction of the rotary shaft 5 and each have a wing shape. The rotary blades 9 are provided around the rotary shaft 5 at equal angles and at equal intervals in the axial direction of the rotary shaft.

  In the illustrated embodiment, the upper and lower rotary pulverized bodies 7 are each provided with eight rotary blades 9 arranged at equal angles around the rotary shaft 5 and also in the axial direction of the rotary shaft 5. The rotary blades 9 are provided, and the positions of the eight rotary blades 9 in the axial direction are close to each other. Further, as shown in FIG. 4, in the rotary blades 9 adjacent to each other in the axial direction, the position around the axis of the upper rotary blade 9 and the position around the axis of the lower rotary blade 9 are shifted. Are arranged.

  Each of the rotary blades 9 in this embodiment is not individually attached to the rotary shaft 5, but as shown in FIG. 3, a wing-like rotation extending in all directions with the center as an attachment portion to the rotary shaft 5. One rotating pulverized body 7 is formed by superposing eight stages of star-shaped metal plates integrally having blades 9 with a gap in the axial direction.

(Cylinder)
The center of the cylindrical body 6 and the rotational center of the rotary pulverizing body 7 arranged inside the cylindrical body 6 are the same, and is a diagram schematically representing the inside of the pulverizing unit 2 as viewed from above. 3, the tip of the rotary blade 9 of the rotary pulverizing body 7 and the inner surface of the cylindrical body 6 are opposed to each other through a narrow space so that they do not come into contact with each other. When the rotary blade 9 is rotated at any angular position, the distance between the tip of the rotary blade 9 and the inner surface of the cylindrical body 6 is the same.

  Since the tip of the rotary blade 9 and the inner surface of the cylindrical body 6 face each other through a narrow space as described above, the outer peripheral position 12 of the rotating region 11 of the rotating pulverized rotating body 7 and the inner surface position of the cylindrical body 6 A gap space 14 is formed between the pulverization unit 2 and the above-described mixture charged from the hopper 15 attached to the lid that covers the upper surface of the cylindrical body 6 when the pulverization unit 2 is operated. The solid roux in the mixture is crushed while colliding with the rotary blade 9 of the pulverized body 7 and the mixture is stirred as a whole, and the mixture that has been stirred by the upper rotary pulverized body 7 is the lower rotary crushed body 7. Falls to the side.

  Similarly, the mixture reaching the lower rotary pulverized body 7 is also stirred as a whole while the solid roux in the mixture is pulverized by the collision with the rotary blade 9 of the lower rotary pulverized body 7. The As a result, below the rotary pulverized body 7 in the lower stage, the granular mixing in a state in which the granular solid roux with the powder raw material adhering to the surface and the powder raw material not adhering to the granular solid roux are mixed Seasoning is discharged.

  The distance between the tip of the rotary blade 9 and the inner surface of the cylindrical body 6, that is, the size of the gap space 14, is obtained when the particle size of the granular solid roux in the powdery mixed seasoning to be obtained is 2 mm. Is about 3 to 6 mm. In addition, the size of the gap space 14 is 3 to 8 mm when the particle size of the desired granular solid roux is 2 mm or less, and if the particle size of the desired granular solid roux is 4 mm or less, 6-16 mm is good. In addition, it has been confirmed that clogging is likely to occur when the particle size is the same as the particle size of the desired granular solid roux, and if it is too wide, it is difficult to obtain the granular solid roux having the desired particle size.

(rectifier)
As shown in FIG. 3, a rectifying plate 16 along the inner circumferential direction of the cylindrical body 6 is attached to a portion of the cylindrical body 6 corresponding to the space 8 between the rotary pulverized bodies 7. In consideration of the workability when the cylindrical body 6 is set to the front end, it is discontinuously provided so as not to be buffered with the tip of the rotary blade 9 when the position is stopped. In addition, when it is set as the structure which can divide the cylindrical body 6 into two, you may make it continue along the inner periphery of this cylindrical body 6. FIG.

  And the baffle plate 16 located in the inner surface of the cylindrical body 6 exceeds the outer peripheral position 12 of the rotational area 11 of the rotary pulverized body 7 in the radial direction of the cylindrical body 6 when viewed from above. It overhangs within the range corresponding to. Further, each of the current plate 16 is inclined downward toward the lower center of the cylindrical body 6.

  In the portion where the upper rotary pulverized body 7 is rotating, the upper rotary pulverized body 7 is pulverized and repelled by the upper rotary pulverized body 7 including the airflow generated toward the inner surface side of the cylindrical body 6 by the rotation of the upper rotary pulverized body 7. There is a flow of the mixture in which the mixture of the granular solid roux and the powder raw material moves downward while moving toward the inner surface of the cylindrical body 6. As described above, the rectifying plate 16 is inclined downward toward the center of the cylindrical body 6, and the upper portion of the rectifying plate 16 winds up while keeping the flow of the mixture along the inner surface of the cylindrical body 6. The upper rotating pulverized body 7 is provided as guide means 17 as a circulating flow A fed toward the center of the rotating region 11 so that the mixture is properly stirred.

  As described above, the mixture is moved up and down in the inner space of the cylindrical body 6 including the space in which the upper rotating pulverized body 7 rotates and the space above the portion where the upper rotating pulverized body 7 is located on the inner periphery of the cylindrical body 6. Since the guiding means 17 for circulation is provided, the solid roux in the mixture is easily pulverized, for example, by being bounced back toward the center of the upper rotating pulverized body 7, and the desired mixture in the granular mixed seasoning There is an effect that it is possible to surely reduce the ratio of the remaining solid roux that is larger than the size.

(Modification-Rotating shaft)
Since the driving force is transmitted to the rotary shaft 5 in the pulverizing unit 2 of the vertical drop pulverizer 1 according to the above-described embodiment, the powdered mixed seasoning after passing through the pulverizing unit can be easily recovered. However, the present invention is not limited to the point that the driving force is transmitted to the upper end side of the rotary shaft 5. For example, if the driving force is transmitted to the lower end side of the rotating shaft, there is a merit that the stability as the device is improved.

(Modification-Rotating pulverized product)
The rotary pulverized body 7 has been described on the assumption that the upper rotary blade 9 and the lower rotary blade 9 in the axial direction (vertical direction) of the rotary shaft 5 are misaligned around the axis. It is not limited. For example, as shown in FIG. 5, in each of the upper and lower rotary pulverized bodies 7, the positions of the upper rotary blade 9 and the lower rotary blade 9 around the axis may be aligned in the axial direction. is there.

(Modification-Rectifier plate shape)
The rectifying plate 5 includes a form in which the current plate 5 is discontinuously arranged at equal intervals along the inner periphery of the cylindrical body 6, a form in which the rectifying plate 5 is continuous with a uniform overhang width along the inner periphery of the cylindrical body 6, and FIG. It is also possible to provide a plurality of recesses 16a to avoid the tip of the rotary blade when inserting the rotating pulverized body in a cut shape on the current plate 16 as shown in FIG.

(Modification-Position of rectifying plate)
In the above-described embodiment, the rectifying plate 16 positioned corresponding to the vacant space 8 with the vacant space 8 as one stage is a portion that is a height position in one place in the vertical direction of the cylindrical body 6. The present invention is not limited to this, and the cavities 8 are provided in a plurality of stages in the crushing section 2, and a current plate is provided at each height position corresponding to the cavities 8. Is possible. In this case, the space corresponding to the current plate may be set at any position between the uppermost position and the lowermost position where the rotary blades are arranged in the rotation axis direction.

  In addition, as in the above embodiment, when the space is only one stage, the center position where the number of rotary blades in the upper and lower stages is the same, and the position lower than the center position (in the upper stage rotary grinding body) It is preferable that the number of the rotary blades is larger than the number of the rotary blades in the lower rotary pulverized body), because the residence time of the mixture in the rotational space of the upper rotary pulverized body becomes longer. It becomes.

(With or without current plate)
Next, whether or not there is a change in the efficiency of pulverization by providing a rectifying plate, when producing the above-mentioned powdered mixed seasoning, a pulverizer that does not have a rectifying plate in the cylindrical body and a rectifying plate are provided. The particle size ratio with a particle diameter of 2 mm or more was examined and examined in the production with a pulverizer.

  In the vertical drop pulverizer used for comparison, eight rotary blades are arranged at equal angles around the rotary shaft inside the cylindrical body with an inner diameter of 300 mm, and the outer diameter is 291.7 mm. Also, a rotating pulverized body with eight rotating blades was arranged. And this rotary crushing body was provided in the upper and lower pairs through the void as mentioned above. As shown in FIG. 4, the upper rotary blade and the lower rotary blade that are close to each other in the vertical direction in the axial direction do not overlap each other around the axis of the rotary shaft, and are alternately arranged in the axial direction.

  As shown in FIG. 3, the current plates are discontinuously positioned in the inner circumferential direction of the cylindrical body, and each is inclined at 45 degrees toward the lower center of the cylindrical body. By this inclination, the mixture is placed in the lower rotation region. The guiding means for guiding is formed.

  Then, the mixture of the powder raw material composed of the small solid roux and the food raw material is added to each of the pulverizer not provided with the rectifying plate and the pulverizer provided with the rectifying plate, and pulverized. The powdery mixed seasoning obtained in the above is collected at the bottom of the cylindrical body, this is pulverized once, and the collected powdered mixed seasoning is re-introduced to reduce the number of times of grinding. The particle ratio (%) having particles having a particle diameter of 2 mm or more was investigated each time, increasing the number of times, three times, four times, five times, and six times. The results are shown below.

Particle ratio with particles of 2 mm or more when there is no current plate Double grinding: 17.4%
Three times grinding: 16.4%
Four times grinding: 14.2%
Five times grinding: 12.4%
Six times grinding: 9.4%

Particle ratio with particles of 2 mm or more when current plate is present Double grinding: 15.8%
Three times grinding: 10.6%
Four times grinding: 5.8%
Five times grinding: 3.2%
Six times grinding: 2.4%

  From the above comparison, the current plate prevents the mixture from directly entering between the lower rotating pulverized body and the cylindrical body, and the flow of the mixture fed toward the cylindrical body by the upper rotating pulverized body. Is reliably guided so that it circulates toward the center of the rotating region of the upper rotating crushed body, and the degree of remaining granular solid roux that becomes particles larger than the desired particle diameter is suppressed to improve the pulverization efficiency I found out that Therefore, the powder which is a mixture of the granular solid roux with the powder raw material attached to the surface and the non-adhered powder raw material by producing the powdered granular seasoning using this vertical drop pulverized product The degree to which granular solid roux larger than the desired particle size remains in the granular mixed seasoning decreases, and a granular mixed seasoning that is easily dissolved in hot water can be obtained.

(Number of rotating blades)
Next, the examination of the number of rotary blades on the plane perpendicular to the rotation axis of the rotary pulverized body will be described. As described above, when the four rotary blades around the rotation axis of the rotary pulverized body in the vertical drop pulverizer described above are arranged at regular intervals around the axis, the particle diameter is 2 mm or more as described above. The particle ratio (%) in which the particles are present is investigated, and the results are shown below.

Particle ratio with particles of 2 mm or more when there are four rotary blades Double grinding: 15.8%
Three times grinding: 10.6%
Four times grinding: 5.8%
Five times grinding: 3.2%
Six times grinding: 2.4%

Particle ratio with particles of 2 mm or more when there are 8 rotary blades Double grinding: 15.8%
Three times grinding: 7.2%

  From the above results, it has been found that arranging the rotary blades so that there are many around the axis of the rotation axis is effective in reducing the particle ratio with particles having a particle diameter of 2 mm or more. Therefore, it is effective to increase the number of rotary blades in order to further reduce the particle ratio in the vertical drop pulverized body provided with the current plate.
