Wheat Flour Japan Wheat Research Society Published January 31, 1976, pp. 274-275

However, in conventional mills, the flour that emerges from the roll machine 890 in buckwheat, wheat, etc. is once lifted upward and sieved with a milling shifter 800 to become a product by the sieved flow path. The milling is performed by repeating these processes, such as passing through the next roll machine 890. With such a structure, there is a problem that a high and huge building for milling such as an eight-story building is required, and the space of the building, particularly the height, is required. Further, in the conventional example, the powder is lifted up to the milling shifter 800 and distributed by the milling shifter 800, and another power is required to lift the powder, and the transportation energy is great. In addition, since the powder freely falls from the milling shifter 800 to the roll machine 890 via the sport pipe 910, the pipe distance is inevitably long, and the burden of the internal cleaning cost is large. Also, the milling shifter 800, the roll machine The inside of the 890 is difficult to clean and maintain, and the vibration-type shifter is labor-intensive to replace the net and clean the inside. In order to prevent contamination in the sport pipe 910, all the sport pipes 910 must be removed. Therefore, the cleaning work and the maintenance are difficult, and the floor has to be moved over a wide area, which requires a lot of labor and time for the cleaning work and management. In addition, there has been an allergy problem in recent years related to the problem of cleaning. For example, when changing varieties such as wheat flour, it is best to grind grains in separate lines, but due to cost problems, it may also serve to grind different kinds of grains in the same line. If the same pulverization line is wheat or buckwheat, powder may be mixed. If the inside of the milling facility is insufficiently cleaned, it is difficult to take measures against human allergies such as buckwheat allergy. In addition, since heat is generated from the milling shifter 800 and the roll machine 890, a chiller (water-cooled cooling device) is required, and the structure is complicated. Furthermore, the shifter 800 for milling and the roll machine 890 have a structure in which the air pressure is released and is not a sealed structure, and sealing performance may be a problem.
Then, this invention makes it a subject to provide the milling equipment which can implement | achieve the ease of cleaning which implement | achieves the size reduction and cost saving of a milling equipment by making a milling equipment planar structure and reducing height.

The present invention can be applied to either whole grain powder or, in particular, milling.

  When a blower, a rotary valve or the like is installed in the upstream line and pressure feeding type pneumatic transportation is used, the inside of the powder body supply side is a positive pressure. Since the rotating disk and the rotating blade member themselves generate wind force (pressure), the inside of the inline mill and the inline shifter has a negative pressure (suction pumping state) and the inside of the outlet has a positive pressure. This negative pressure assists the positive pressure, the air-fuel mixture tends to flow downstream, and the pressure loss becomes very small. In suction-type pneumatic transportation, negative pressure and negative pressure act.

In the invention according to claim 2, the in-line mill and the in-line shifter are connected in a plurality of stages, and the granular material taken out from the outlet outlet without passing through the sheave of the in-line shifter is transferred to the next-stage in-line mill.

Accordingly, the rotating disk can serve as the pulverizing power, the rotating blade member can serve as the sieving power, and the rotating disk and the rotating blade member can also serve as the power for pneumatic transportation of the pulverized powder particles in the milling line. The pneumatic transportation direction of the powder particles is a direction from the inline mill toward the inline shifter.

  It can also be applied when there is no wind power supplied to the first-stage in-line mill, such as small-scale milling equipment. In this case, a wind power amplifying device that amplifies the atmospheric pressure is obtained.

The blades of the rotary blade member are preferably accommodated in the sheave. An extension of the blade from the sheave to the supply chamber is also preferred.
The supply chamber preferably has a smaller volume than the sieving chamber.
When setting to a compact size, it is preferable that the length of the supply chamber in the axial direction of the rotating shaft is shorter than the length of the sieving chamber. For example, the range of 1/3 to 1/5 is preferable.

The diameter of the air-fuel mixture inlet is preferably smaller than the diameter of the air-fuel mixture receiving part. The gas mixture inlet is preferably a tube.

  In the in-line shifter, it is preferable that all or a part of the plurality of blades extend from an inner region of the sheave to the supply chamber of the air-fuel mixture receiving unit. For example, when a rotary valve and a blower are installed in the upstream line, since the air-fuel mixture supplied from the air-fuel mixture inlet pulsates at the beginning of pneumatic transportation, the supply into the sheave may become unstable. The pulsation phenomenon of the air-fuel mixture is alleviated by the extended rotating blade member, and the air-fuel mixture can be stably supplied into the sheave.

Milling targets are wheat, buckwheat, soybeans, red beans, coffee beans, corn, dried noodles, rice crackers, noodle mills, and the like.

  First, when the in-line mill 1 of the specific example 1 applied to the milling equipment 200 to 800 of the present embodiment is installed in the milling line as shown in FIGS. It is installed at the first stage of the milling line, has a raw material inlet 2 at the top, and a belt conveyor 3 is installed under the raw material inlet 2 for safety. The raw material charged from the mouth 2 is conveyed by the belt conveyor 3 to the cutter unit 4 positioned below the belt conveyor 3, and the raw material cut and crushed to a certain size by the cutter unit 4 is discharged to the hopper 5. And is supplied to the screw feeder 6. An air intake device 7 also serving as a silencer is provided at the outlet of the screw feeder 6. A crushing chamber 11 is formed in a main body casing 10 having a supply port 8 and a discharge port 9. An opening / closing door 12 used for opening / closing the grinding chamber 11 is connected to the main casing 10. The supply port 8 is formed in the central portion of the open / close door 12. The air intake device 7 prevents noise from the crushing chamber 11. The main body casing 10 has a rectangular shape and is thinner than the height and width.

  As shown in FIGS. 2 and 3, the crushing chamber 11 is provided with a rotating disk 13 in the wall direction, and a chopper having a shape in which three cross-shaped rotating blades are stacked on a rotating shaft 14 at the center of the rotating disk 13. 15 is attached. The rotating shaft 14 is disposed at the center in the thickness direction of the main body casing 10, the distal end protrudes into the crushing chamber 11, and the proximal end is disposed rearward. A chopper 15 attached to the rotating shaft 14 is structured to rotate at high speed coaxially with the rotating disk 13 by a drive motor 19 (see FIG. 1) connected to the rotating shaft 14 by a belt 14a. Then, the pulverized raw material cut by the cutter unit 4 is quantitatively supplied to the coarse pulverization unit 16 which is the region of the central portion of the pulverization chamber 11 by the screw feeder 6 and coarsely pulverized. An inner portion surrounded by a dotted line in FIG. Depending on the type of object to be crushed, the coarse pulverization unit 16 may be omitted.

  For example, a raw material that is a lump of a certain size, such as soybeans, dry noodles, bread or the like, is sheared into granules by the chopper 15 and crushed. The chopper 15 is particularly suitable for shearing a raw material that is strong in impact and crushing, which is rich in flexibility and elasticity, and for crushing a solidified powder lump. The crushing chamber 11 in the line generates a suction air volume by a rotating disk 13 that is rotated at high speed by a drive motor 19 and functions in the same manner as a blower. To the coarse pulverization unit 16. That is, the turntable 13, the coarse crushing unit 16, and the fine crushing unit 17 function as a crushing device and a wind power amplifying device.

  The cutter part 4 cuts the raw material input from the raw material input port 2 to a certain size. For example, dry noodles, dry seaweed, bread, noodle scraps, solidified food powder lump, etc. are cut with a sharp blade to have a certain size. Depending on the type of object to be crushed, such as soybeans or crackers, the cutter unit 4 does not necessarily need to be cut, so the cutter unit 4 can be omitted.

As shown in FIGS. 4 and 5, a plurality of impact pins 22 are fixed to the surface portion 13 a of the turntable 13 around the coarse pulverization unit 16, and the inside (opening side of the pulverization chamber) of the opening / closing door 12 of the pulverization chamber 11. A plurality of comb-shaped impact pieces 23 formed so as to be able to rotate the gap between the impact pins 22 are arranged in an annular shape on the fixed platen 18 fixed to the side surface. The impact piece 23 is formed by concentrically fixing three annular teeth 23a to 23c. In this specific example, the ring-shaped teeth of the impact piece 23 are arranged in three rows, but an appropriate number of rows can be arranged depending on the application.
When the coarsely pulverized raw material coarsely pulverized by the chopper 15 of the coarse pulverization unit 16 is pulverized to a size enough to pass through the gap 20 of the innermost ring-shaped teeth 23a, the coarse pulverization unit is caused by the centrifugal force of the rotating disk 13. 16 is diffused to the surrounding finely pulverized portion 17.

  As shown in FIG. 6, the coarsely pulverized raw material diffused in the fine pulverization unit 17 is impacted by a plurality of impact pins 22 fixed to the rotating disk 13 and a plurality of impact pieces 23 fixed to the stationary disk 18. In addition, pulverization caused by the collision between the coarsely pulverized products, and further circulating from the fine pulverization unit 17 to the coarse pulverization unit 16, is again subjected to the shearing action of the chopper 15 and finely pulverized in a short time. It is. In this way, the pulverized raw material supplied to the central portion of the pulverization chamber 11 is diffused from the coarse pulverization unit 16 to the fine pulverization unit 17 together with the air flow, and is finely crushed by receiving the impact of the impact pin 22 and the impact piece 23. Then, it passes through the gap 20 between the outermost ring-shaped teeth 23c, passes through a cylindrical screen 21 attached to the outer peripheral surface of the crushing chamber 11, is sized to a desired particle size, and is discharged as fine powder (product). 9 is discharged.

  In addition, a lock device 25 that opens and closes the open / close door 12, a hanging portion 26 for hooking and lifting the hook, and a hinge portion 27 that rotates the open / close door 12 are provided.

  According to the in-line mill 1 of the specific example 1 described above, the crushing chamber 11 generates a suction air volume by the rotating disk 13 that rotates at a high speed, and functions like a blower. Since secondary air is smoothly taken in from the apparatus 7, it is not necessary to separately provide a blower, which contributes to downsizing of the milling equipment line.

  Next, the in-line mill 101 installed in-line on the powder production line of the specific example 2 will be described with reference to FIGS. This in-line mill 101 is mainly used for milling wheat, buckwheat and the like, and removes the raw material input port 2, the belt conveyor 3, the cutter unit 4, the hopper 5 and the air intake device 7 from the in-line mill 1, The position of the discharge port 109 is changed, the motor 119 is directly connected, the structure is further simplified, and the base 130 for fixing the main body casing 110 to the upper part is provided. Since the inside of the specific examples 1 and 2 has a common structure, the corresponding part number is added with the number 100, and the description is used.

  According to the inline mill 101 of the specific example 2 described above, the air-fuel mixture is received and the granule is milled, and the air-fuel mixture is discharged to the downstream inline shifter 201, so that it is not necessary to separately provide a blower. This contributes to downsizing of the milling equipment line.

  Next, the in-line mill 151 installed in-line on the powder production line of the specific example 3 will be described with reference to FIG. This in-line mill 151 is mainly used for milling wheat, buckwheat, etc., and the coarsely pulverized portion 16 is removed from the in-line mill 101 of Example 2 and the structure in which the impact pins 22 are densely formed is changed. The position of the discharge port 9 is changed. Since the other parts have the same structure as that of the first and second examples, the corresponding part number is assumed to be in the 150s, and the description is incorporated. The explanation and illustration of the internal structure are also incorporated with the in-line mills 1 and 101 of the first and second examples.

A cylindrical sheave 207 is coaxially provided in the sieving chamber 251 so that the rotation shaft 206 passes through the center thereof. An inner region 253 of the sheave 207 communicates with the supply processing chamber 231. As a result, the sieving chamber 251 has a substantially double cylindrical structure divided into an inner region 253 and an outer region 254 by the sheave 207. An outlet pipe 210 is attached to the lower end of the through outlet 252.
The rotary shaft 206 has a single-bearing structure, and its free end protrudes to the vicinity of the right end of the sheave 207 inside the sieving chamber 251.

The mesh of the sheave 207 is set to be finer (for example, 0.5 mm) than the conventional one. The sheave 207 is detachably fixed to the sieve casing 250 by a sheave fixing tool 255.

  As shown in FIGS. 15 and 16, a rotary blade member 208 is provided in the inner region 253 of the sheave 207 on the outer diameter portion of the rotary shaft 206. The rotary blade member 208 includes a plurality of (here, two) radial shape bodies 281 (see FIG. 16A) disposed at both ends of the region of the rotary shaft 206 inside the sheave 207, and these radial shapes.

A plate-shaped scraper 283 that is attached to the blade 282 of the portion and protrudes slightly outward in the radial direction from the blade 282, and a tip end surface of which forms a gap with respect to the inner diameter surface of the sheave 207 and scrapes the powder out of the sheave 207 (FIG. 16). (See (b)), and has a pie-shaped structure in front view and a cross-shaped structure in side view. The scraper 283 includes a groove 283 a for accommodating the radial shape body 281 and a fixing hole 283 b for attachment to the blade 282.

  The radial shape body 281 has a cross shape in which the protruding portions radially protrude in the side view. A circular hole 281a for inserting and fixing the rotary shaft 206 is provided at the center of the radial shape body 281. Each protrusion 281b includes a notch 281c at the tip. Further, the base end side (passage 237 side) of the blade 282 has a cutter shape (for example, a triangular shape). As shown in FIG. 16A, the positions of the two radial shaped bodies 281 are arranged at a predetermined rotation angle so that the rotation positions are shifted in a side view. The radial shape body 281 is set to a number corresponding to the number of blades 282 and a shape corresponding to the shape of the blades 282.

The blades 282 are configured such that a predetermined number (four in this case) forms a predetermined angle (here, 90 degrees). The blade 282 is slightly bent at both ends, but may be linear. The blade 282 has a long plate shape when viewed from the front. Although not shown, the longitudinal section of the blade 282 is a shape that is chamfered in a square with respect to a direction orthogonal to the axial direction of the rotating shaft 206.

In addition, inspection ports 218 and 219 are respectively provided in the center portion of the inspection door 209 and the front portion of the sieve casing 250 so that the state inside the sieve casing 250 can be visually confirmed. Further, an oversized outlet 222 is formed on the inspection door 209 for discharging the oversized powder (powder that could not pass through the sheave) inside the sheave 207 to the outside.

  Next, the operation of the inline shifter 201 will be described with reference to FIGS. The in-line shifter 201 of this specific example is a so-called in-line type sieving machine, which is operated in the middle of the milling line L. Accordingly, the mixture of the powder and air supplied from the upstream milling line L1 of the inline shifter 201 is subjected to a sieving process, and the powder is supplied to the downstream milling line L2 after removing the lumps, crushing or removing foreign matter. It is supposed to be sent. Hereinafter, the powder separation process inside the inline shifter 201 will be specifically described.

  First, the upstream line L 1 is connected to the powder inlet 204, and the downstream line L 2 is connected to the through outlet 252. When the motor 211 rotates, the rotary shaft 206 and the rotary blade member 208 rotate integrally, and when a mixture of powder and air is continuously supplied from the powder inlet 204 to the supply processing chamber 231 in the tangential direction. Then, the gas is forced to flow into the sieving chamber 251 and reaches the inner region 253 of the sheave 207.

  Inside the sheave 207, the rotating blade member 208 is rotated at a high speed by the rotation of the rotating shaft 206, so that the blade 282 and the radial shape body 281 of the rotating blade member 208 agitate the air-fuel mixture. When the rotating blade member 208 starts stirring, the powder is removed and broken by the stirring of the air-fuel mixture performed by the blade 282. Further, powder lumps stuck to the mesh of the sheave 207 are removed by the blades 282. In this way, the air-fuel mixture containing finer powder than the mesh of the sheave 207 is sent to the outer region 254, the air-fuel mixture reaches the through outlet 252 and is discharged to the downstream line L2, and the powder or foreign matter larger than the mesh of the sheave 207 is removed. It remains in the inner region 253.

  Further, since the rotary blade member 208 sucks the air-fuel mixture from the powder receiving part 203 and discharges it from the through outlet 252, the main role is the same as the fan. The wind force itself generated by the mechanical rotation of the rotary blade member 208 becomes an intermediate auxiliary energy amplifying device of the milling line, which sends out the air-fuel mixture and performs a turbo action. That is, there are a rotary valve and a blower in the upstream line L1, and when powder is supplied from here, the inside thereof is at a positive pressure, but the rotating blade member 208 itself produces wind force (pressure). Therefore, the supply casing 230 has a negative pressure, and the through outlet 252 has a positive pressure. This negative pressure assists the positive pressure, making it easier for the air-fuel mixture to flow downstream and reducing pressure loss very much.

  On the other hand, the sieving operation of the inline shifter 201 is repeated and the powder is discharged from the outlet 222 through the inner region 253. Further, the internal state is visually confirmed from the inspection ports 218 and 219, and when the removal is necessary, the operation is stopped, the mounting knob 215 of the inspection door 209 is loosened, and the inspection door 209 is opened with the handle 216. . Since the inside of the sieving chamber 251 is exposed, the inside of the sheave 207 returns to a clean state by removing the powder and foreign matters remaining inside. To replace the sheave 207, the sheave 207 is taken out from the sieving chamber 251 and a new sheave is inserted. To clean the sheave 207, the sheave 207 is taken out from the sieving chamber 251 and cleaned, and then returned to the original position.

According to inline shifter 201 described above, mixed by mechanical rotation force of the rotating blade member 208, the suction airflow generated, since a similar role as the blower, smoothly from the in-line mill 1,101,1 51 Therefore, it becomes unnecessary to provide a separate blower, which contributes to downsizing of the milling equipment line.

  The milling equipment 200, 300, 400, 500, 600, 700, 800 according to various embodiments of the present invention will be described with reference to FIGS. These milling facilities solve various problems of the conventional large-scale milling facilities shown in FIGS. Examples of processing targets for milling include wheat, buckwheat, soybeans, red beans, maize, corn, and coffee beans.

  The milling equipment 200 of FIG. 17 is incorporated in the milling line L as a multistage structure in which the inline mill 101 and the inline shifter 201 are combined and connected in series, and are arranged in a plane on the same floor. The number of stages can be set as appropriate. First, the inline mill 101 and the inline shifter 201 are connected. The supply port 108 of the inline mill 101 is connected to the upstream side, and the raw material is mixed with powder and gas by aerodynamic transportation or with a screw feeder or the like. While accepting a granular material, the discharge port 109 of the in-line mill 101 is connected to the inlet 204 of the in-line shifter 201 by piping. Further, the outlet 222 of the inline shifter 201 and the rotary valve 220 are connected, the rotary valve 220 and the pressure feeding adapter 221 are connected, and the rotary valve 220 and the supply port 108 of the next-stage inline mill 101 are connected by piping. In this way, the inline shifter 201 and the inline mill 101 are alternately connected one after another and arranged in a plane. The rotary valve 220 is operated in synchronism with the operation of the inline shifter 201, and includes an air lock means, and performs quantitative discharge of the granular material while performing air lock (gas shut-off). The granular material pulverized by the in-line mill 101 is supplied to the in-line shifter 201 and applied to the sheave 207, and the powder (through portion) as a product that has passed through the sheave 207 is taken out from the through portion outlet 252. . On the other hand, the powder that has failed to pass through the sheave 207 of the inline shifter 201 (powder and granular material having a diameter larger than the mesh diameter of the sieve) is transferred to the next inline mill 101 by the rotary valve 220 via the oversized outlet 222. Then, it is further pulverized. Although the rotary valve 220 is provided in the outlet outlet 222, the rotary valve 220 having an air lock function may be provided in the outlet outlet 252 instead. The reason why the rotary valve 220 provided with the air lock means is provided is to allow the gas to pass through the outlet outlet 222 and the outlet outlet 252 in a balanced manner. That is, the gas entered from one place is discharged from one place. The boost effect of the in-line mill 101 and the in-line shifter 201 can eliminate the power source, greatly reduce the conventional large-scale milling equipment, simplify cleaning, and prevent contamination due to insufficient cleaning. There is. In addition, about piping, it shows with a dotted line in a figure and abbreviate | omits the number and description. The gas may be air or inert gas.

  The buckwheat flour milling equipment 300 in FIG. 18 is incorporated in the milling line L as a multi-stage structure that is connected in series in combination with the inline mill 101 and the inline shifter 201, and arranged in a plane on the same floor. is there. First, since the connection form of the in-line mill 101 and the in-line shifter 201 is substantially the same as that of the milling equipment 200 of FIG. 17, the description will be used, but in this FIG. 18, the sheave 207, the over outlet 222, and the sieving chamber 251. In addition, an air intake port (also referred to as a pneumatic shoe) 240 is disposed at the supply port 108 of the first in-line mill 101 and downstream of each rotary valve 220. The powder is pneumatically transported by the air taken in from the air intake port 240, and is crushed and sieved. The powder (through part) that has passed through the sheave 207 of the inline shifter 201 is taken out from the through part outlet 252, and the powder that could not pass through the sieve of the inline shifter 201 (over part) is taken out from the over part outlet 222. The powder from the excess outlet 222 is pulverized by the in-line mill 101 through the rotary valve 220 and supplied to the next in-line shifter 201. An air intake port 240 is installed under the rotary valve 220. The lines other than the air intake port 240 are closed lines. Note that the screen 21 is not provided in the three preceding stages of the inline mill 101, and the screen 21 is provided in the two subsequent inline mills 101. This is because when the screen 21 is inserted, the powder stays inside due to the resistance of the screen 21 and the raw material is excessively crushed. The screen 21 is necessary for pulverization at a later stage where quality is not high, or for whole-grain pulverization in FIGS. 21 and 22. Pollen from the through outlet 252 of the first inline shifter 201, 1st powder from the through outlet 252 of the second inline shifter 201 (1F), 2nd powder from the through outlet 252 of the third inline shifter 201 (2F) The third equivalent powder (3F) is extracted from the through outlet 252 of the fourth in-line shifter 201, and the cuticle powder is extracted from the fifth in-line mill 109. That is, it is taken out from the fine powder in order from the upstream side. This produces the same effect as the milling equipment 200. The black skin powder is processed in a separate in-line mill. In addition, about piping, it shows with a continuous line in a figure and a number and description are abbreviate | omitted.

  The buckwheat flour milling equipment 400 of FIG. 19 is incorporated in the milling line L as a multistage structure that is connected in series in combination with the inline mill 101 and the inline shifter 201 and is planar on the same floor (for example, the first floor or the second floor). It is another form arrange | positioned in. First, since the connection form of the in-line mill 101 and the in-line shifter 201 is substantially the same as that of the milling equipment 300 in FIG. 18, the description will be used, but in FIG. 19, the rotary valve 220 and the air intake (pneumatic) in FIG. (Also referred to as a shoe) 240 is removed from the excess outlet 222, but the excess outlet 222 is directly connected to the supply port 108 of the in-line mill 101 to form a sealed structure. A rotary valve 420 is installed at the outlet of the through outlet 252. An air intake port 440 and a receiver filter 560 with a blower are installed in the milling line L. This produces the same effect as the milling equipment 200. In addition, about piping, it shows with a continuous line in a figure and a number and description are abbreviate | omitted.

  The milling facility 500 in FIG. 20 is common to the above-described facility in that the milling line L includes an inline mill 101 and an inline shifter 201 that are alternately connected in series in a plurality of stages. A powder storage container 590 is installed in a through outlet 252 of 201. In addition, an oxygen concentration meter 591, a blower 592, an after cooler 593, a nitrogen gas control valve 595 for controlling the supply of the nitrogen gas supply source 594, a dumping server 596 for supplying powder, and a damping are sequentially provided upstream of the first inline mill 101. A rotary valve 597 for connecting the server 596 to the milling line L is provided. In addition, the outlet 222 for the end of the rearmost inline shifter 201 is connected to the tank 598 so that air is returned to the upstream side by the blower 599. Further, a rotary valve may be installed in place of the storage container 590, and a classifier 585 may be connected thereto, so that the storage container 590 can classify the powder with a tank 586 installed on the discharge side (in the figure). (Refer to the part surrounded by the chain line.) The aftercooler 593 includes a chiller, a pump, a water supply device, and the like. The first powder (1F) is discharged to the first storage container 590, the second powder (2F) is discharged to the next storage container 590, and the third powder (3F) is discharged to the last storage container 590. The fourth equal powder (4F) is stored in the tank 598. That is, it is discharged from the fine powder in order from the upstream side. This produces the same effect as the milling equipment 200 to 400, but the rotary valve 220 is unnecessary, so that a smaller milling equipment can be obtained. In addition, about piping, it shows with a continuous line in a figure and a number and description are abbreviate | omitted.

The milling facility 600 of FIG. 21 is basically the same as the milling facility 300 of FIG. 18, and therefore, explanations and illustrations of common parts will be made using the part numbers as 600 series, and different parts will be explained. The different part is that the nitrogen gas is circulated through the milling line L, the in-line mill 101 and the in-line shifter 201 are alternately connected in multiple stages (here, three stages), and the dotted line part is the nitrogen gas flow path 642. The nitrogen concentration meter 643 and the nitrogen supply unit 644 are installed, and the first grade powder (1F) and the second grade powder (2F) discharged from the in-line shifter 201 are protected by the nitrogen gas, and the third grade powder. Is treated with air. The first and second powders discharged from the through outlet 252 of the inline shifter 101 are respectively stored in a silo facility 645 having a silo unit 645a and a silo unit 645b each having a receiver filter 660. . The two receiver filters 660 separate nitrogen and powder and recycle the separated nitrogen gas to the milling line L. The first in-line mill 101 of the milling line L has a nitrogen gas line 642 connected to the front stage thereof, and a receiver filter 660-1 and a rotary valve 620-1 installed downstream thereof, from which the seeds that are raw materials are supplied. It has become so. The nitrogen gas line 642 has a sealed structure. In addition, a rotary valve 620 is connected to each of the outlets 222 of the last stage and the preceding inline shifter 201, and an air intake port 640 is installed there. Reference numerals 678 and 679 are valves. This produces the same effect as the milling equipment 300, but further, the powder is transported by nitrogen gas, and pulverization and sieving are performed in a nitrogen gas atmosphere. It is possible to contain the aroma and flavor of granules. In addition, it can be applied to coffee beans. In addition, about piping, it shows with a continuous line and a dotted line in a figure, and a number and description are abbreviate | omitted. Solid lines indicate air piping, and dotted lines indicate nitrogen gas piping.

Although the above-described milling equipment 200 to 600 is a fractional milling system, the milling equipment 700 in FIG. 22 is a nitrogen gas type whole grain milling system. The in-line mill 101 and the in-line shifter 201 are set and repeatedly connected in series. A rotary valve 720 is installed in each through outlet 252 of the plurality of in-line shifters 201. The discharged powder is joined together with the powder discharged from the in-line mill 101 connected to the in-line shifter 201 at the final stage. Further, the raw material is supplied to the milling line L from the first receiver filter 760-1 via the rotary valve 720-1. Further, the powder and nitrogen gas are separated by the second receiver filter 760-2, and the powder that is milled in the whole product is stored in the product silo via the rotary valve 720-2. On the other hand, the nitrogen gas separated by the receiver filter 760-2 is connected so as to return to the first in-line mill via the valves 778 and 779, the nitrogen supply unit 744, the nitrogen concentration meter 743, and the first receiver filter 760-1. The milling line L constitutes a nitrogen gas closing system. Thus, whole grain milling is performed in a nitrogen gas atmosphere. Although the nitrogen gas effect similar to that of the milling facility 600 is produced, since the milling process can be performed in a deoxygenated state by the whole grain milling, it is possible to contain the aroma and flavor of all the processed powders. In addition, it can be applied to coffee beans. The medium is nitrogen gas, but it may be changed to air. In addition, about piping, it shows with a dotted line in a figure and abbreviate | omits the number and description.

  Since the milling equipment 800 of FIG. 23 is a whole grain milling system similarly to the milling equipment 700, description of common elements is incorporated. The difference between the milling equipment 800 and the milling equipment 700 is that the equipment is simpler. That is, a plurality of (in this case, two) inline mills 101 are connected in series, and one inline shifter 201 is connected thereto. The rotary valve 820 is connected to the outlet 222 for the excess. The excess granular material discharged from the rotary valve 820 is recirculated to the first receiver filter 860-1 together with the air from the blower 870, where it is combined with the raw material, and the first in-line is supplied from the rotary valve 820-1. The raw material is supplied to the mill 101 together with nitrogen gas. The powder discharged from the through outlet 252 is transported to the second receiver filter 860-2, where the powder and nitrogen gas are separated, the powder is stored in a milling silo, and the nitrogen gas is fed with the milling equipment 700. Similarly, it is designed to be recycled. In addition, about piping, it shows with a dotted line and a continuous line in a figure, and a number and description are abbreviate | omitted. Solid lines indicate air piping, and dotted lines indicate nitrogen gas piping.

  According to the milling equipment 200 to 800 to which the inline mill 101 and the inline shifter 201 of this specific example are applied, the milling equipment is arranged in a plane by combining the inline mill 101 and the inline shifter 102 and repeatedly connecting them in multiple stages. There is an advantage that can be. As a result, the height of the building (usually 4 stories to 8 stories) can be greatly reduced to 1, 2 stories, etc., so construction costs and equipment costs have been drastically reduced to approximately 1/3 to 1/5. As a result, running costs and management costs can be greatly reduced and energy can be saved. Further, since the rotation itself of the rotating blade member 208 having the rotating plate 13 functioning as a wind power amplifying device of the in-line mill 101 and the blade 282 of the in-line shifter 201 serves as a power source, the pulverization power, sieving power, and power of pneumatic transportation are provided. The power for lifting the powder from the roll machine 890 to the milling shifter 800 becomes unnecessary. Further, the inline shifter 201 can easily replace the network, and management costs can be greatly reduced. The inline mill 101 and the inline shifter 201 are easy to clean and easy to clean in the line. Furthermore, the piping distance of the line can be shortened. You can easily change the variety of grains. When the in-line mills 1, 101, 151 and the in-line shifter 201 have a sealed structure, they are hygienic in-line and there is no room for foreign matter to enter. Even when an air intake device (also used as a silencer) is provided in the in-line mill 101, there is no problem if a filter is provided. In the case of a sealed type, there is an advantage that an inert gas such as nitrogen gas can be used. In the case of the sealed type, since the wind always flows, the equipment and powder are naturally air-cooled, the chiller is unnecessary, and the powder does not heat, so the quality of the powder does not deteriorate. Furthermore, since the sport piping can be eliminated, it is possible to reduce the labor of removing and cleaning the sport piping and cleaning, and to prevent contamination (contamination) including human allergies, thus contributing to the realization of a sanitary environment. Can do.

  The present invention is not limited to the above-described embodiments, and modifications and the like can be made without departing from the technical idea of the present invention. Etc. are also included in the technical scope of the present invention. For example, in each of the facilities 200 to 800, the inline mill 1 or 151 may be installed instead of the inline mill 101. Depending on the purpose of use, the rotary valve 620 in FIG. 21 may be moved to the through outlet 252.
