Description

  The present invention relates to an improvement of a iron making apparatus for producing a firewood.

An iron making apparatus capable of industrially producing a large amount of soot has been put to practical use (see, for example, Patent Document 1).
Japanese Examined Patent Publication No. 47-43076 (Fig. 2)

Patent document 1 is demonstrated based on the following figure.
FIG. 6 is a diagram for explaining the basic configuration of a conventional ventilated iron making apparatus, in which the soot substrate layer 102 placed on the perforated plate 101 is relatively moved from the left to the right in the figure. During this time, air whose humidity and temperature are adjusted is passed through the soot substrate layers 102 and 107 from the bottom to the top.

  Stirring screws 103, 103 are inserted into the moving soot substrate layer 102 from above, and these screws 103, 103 are rotated by an electric motor 106 through gears 104, 104 and bevel gears 105, 105. Care is appropriately performed by stirring the soot substrate layer 102 with the stirring screws 103 and 103. The purpose of care is as follows. (1) Fresh air is replenished to the sputum substrate 107, thereby assisting the growth of bacilli. (2) Appropriately lower the temperature of the rice cake whose temperature has risen. (3) Discharge carbon dioxide and other unnecessary gases accumulated in the sputum due to the respiratory action of bacilli. (4) Loosen the tightened lump or tank. (5) Disperse moisture. (6) Mix the straw uniformly. By performing such care appropriately, good quality can be obtained.

As the cocoon substrate 107 grows, the mycelium grows and engages and tightens, and the cocoon layers are gradually and integrally joined together. This lump is called “dama” in the field, but it is called “bamboo ball” or “ball” below.
Since it becomes impossible to ventilate the center of the jade ball, if left untreated, the coral substrate in the center of the ball will be altered. The air agitating screws 103 and 103 also have a role of crushing so as not to generate such balls.

FIG. 7 is an enlarged view of part 7 of FIG. 6 and shows the balls 108 present on the upper surface of the cocoon substrate layer 102. It was found that the ball 108 did not have the crushing action of the stirring screw 103 and remained as a lump. The reason is as follows.
The cocoon substrate layer 102 is in a state in which the gonococcal hyphae are engaged with each other and tightened together. However, the balls 109 that are partially generated by the rotation of the stirring screw 103 are the surrounding cocoon substrate in the lower layer portion. No problem arises because it is crushed and crushed uniformly. However, in the upper layer portion (surface layer portion), the balls 109 do not get caught with the surrounding wrinkle substrate, and thus float as they are on the surface layer portion. This floating ball 108 becomes a problem.

  In order to maintain the quality of the cocoon and increase the production yield, it is necessary to effectively crush the cocoon balls, and an apparatus for that purpose is required.

  This invention makes it a subject to provide the technique which can crush efficiently the ball of the cocoon which floats on the upper surface during stirring of the cocoon substrate layer.

In the invention according to claim 1, in the slag making tank, a movable floor that moves horizontally and has air permeability is disposed, and a slag substrate that is a processing target is placed on the movable floor to form a slag substrate layer, Air that regulates humidity and temperature is sent under the moving bed and vented upward to the soot substrate layer, and a vertical stirrer is inserted into the soot substrate layer from above and stirred to produce soot. In the type iron making device,
The iron making apparatus includes an inclined plate that is inclined so that the upper surface of the soot substrate layer is leveled and relatively horizontally moved, and has a height that the soot substrate cannot get over at that time. A feature of the present invention is that the cocoon balls appearing on the upper surface of the cocoon substrate layer can be crushed.

  The invention according to claim 2 is characterized in that the machine frame supporting the vertical stirrer is an elevating frame, and an inclined plate is attached to the elevating frame.

  The invention according to claim 3 is characterized in that the inclined plate is a mesh plate.

  The invention according to claim 4 is characterized in that the mesh plate has a side of the eyes of 2 to 3 cm.

In the invention according to claim 1, the iron making apparatus includes an inclined plate, and the inclined plate floats near the upper surface of the straw substrate layer during the stirring of the straw substrate layer, and is crushed by compressing or colliding. Or level the top surface.
Therefore, according to the first aspect, even if the cocoon ball floats up, it can be crushed by sandwiching it between the inclined plate and the cocoon substrate on the upper surface and pinching it. The soot substrate can be properly treated, improving the quality of the soot and increasing the productivity.

  In the invention which concerns on Claim 2, the machine frame which supports a vertical stirrer was made into the raising / lowering frame, and the inclination board was attached to this raising / lowering frame. The inclined plate may be fixed to the upper part of the iron making tank, but the bracket for mounting becomes large-scale. In this regard, in claim 2, attention is paid to the machine frame that supports the vertical stirrer, and an elevating plate is attached to the machine frame. As a result, the mounting bracket can be omitted or downsized.

  In the invention according to claim 3, the inclined plate is a mesh plate. The slanted net is easy to catch the balls of the reeds, and exerts the effect of very easily and finely crushing with the wire constituting the net. In addition, a part of the cocoon substrate passes through the mesh. At this time, if the size of the mesh opening is adjusted, the cocoon balls can be finely broken into a more preferable size.

In the invention according to claim 4, the mesh plate has a side of the eyes of 2 to 3 cm. If the mesh is less than 1 cm, particularly in the case of soy sauce cake, the straw substrate may adhere to the mesh or become clogged, and the function as the mesh plate may be lost. Alternatively, frequent cleaning is required. Moreover, when the mesh exceeds 5 cm, the function as a mesh plate is reduced, and there is a risk of alteration in the cocoon substrate at the center of the cocoon balls passing through the mesh.
In order to exhibit the original function of the mesh board and to maintain the quality of the soot substrate, it is effective to set one side of the mesh plate to a range of 1 to 5 cm, more preferably a range of 2 to 3 cm.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. In addition, although various forms, such as a cylindrical type, a square cylinder type, and a rectangular shape, are practically used for the iron making tank, in this example, a cylindrical iron making apparatus will be described below as an example.

  FIG. 1 is a cross-sectional view of the iron making apparatus according to the present invention. The iron making apparatus 10 is a cylindrical iron making tank 13 having an air inlet 11 and an air outlet 12 and is rotated around the center of the iron making tank 13. A freely-rotating rotary column 14, bevel gears 15, 16 that rotate the rotary column 14 at a low speed, a speed reducer 17, a rotating electric motor 18, and the rotary column at a certain distance above the bottom plate 19 of the iron making tank 13. 14, a breathable moving floor 21 fixed to 14, a peripheral wall 22 fixed to the iron making tank 13 with a slight gap from the outer edge of the moving floor 21, and a space filled with the space formed by the peripheral wall 22 and the moving floor 21 In order to stir the substrate 23, a plurality of vertical stirring blades 25 (... are shown, the same applies hereinafter) inserted from above the substrate layer 24, and these stirring blades 25 ... are rotated. Elevating frame 26 that supports freely, stirring blade 25 A speed reducer 27 and a stirrer motor 28 provided on the elevating frame 26 to rotate the elevating frame 26 in a predetermined direction, and elevating jacks 31, 31 provided on the ceiling 29 of the iron making tank 13 to elevate the elevating frame 26 A connecting pipe 34 that connects the speed reducer 32 and the lifting motor 33 for operating the lifting jacks 31, 31, the air outlet 11 provided at a position above the peripheral wall 22, and the air inlet 12 provided at a position below the moving floor 21. And an air conditioner 36 for adjusting the humidity and temperature of the air and a blower 35 interposed in the communication pipe 34. An inclined plate 42 is attached to the lifting frame 26.

It is desirable to add the following elements to the above basic components.
Reference numeral 37 denotes a guide cylinder that supports the upper portion of the rotary column 14, and 38 and 38 denote guide rails that guide the elevating frame 26 up and down.
The breathable moving floor 21 is preferably a perforated plate, a lattice plate, or a net plate having numerous holes in a flat plate.

The basic operation of the iron making apparatus 10 having the above configuration will be described.
The soot substrate 23 is filled on the breathable moving bed 21 to form a soot substrate layer 24 having a height of about 50 cm. And the air which adjusted humidity and temperature to the predetermined value with the air conditioner 36 is sent, and this soot substrate layer 24 is ventilated through the countless hole of the movable floor 21 from the bottom to the top. If the koji substrate 23 is soy sauce koji, it is treated for 3 days.

During the treatment, the stirring blade 25 may remain inserted in the soot substrate layer 24, but in this example, the stirring blade 25 is moved up and down. That is, the stirring blade 25 is made to wait upward so that the elevating frame 26 is in the position of the imaginary line during most of the time during the iron making.
Then, for example, the next stirring process is performed once every 15 hours, 30 hours, and 40 hours after the start of ironmaking.

  While rotating the stirring blade 25 at a predetermined speed, the lifting frame 26 indicated by an imaginary line is lowered to the position shown in FIG. At the same time, or before or after that, the rotating motor 18 is energized, and the rotating column 14 is rotated via the speed reducer 17 and the bevel gears 16 and 15. By this action, the moving bed 21 is rotated once over about 50 minutes.

  FIG. 2 is a cross-sectional view taken along the line 2-2 of FIG. 1, and the soot substrate layer 24 is stirred by the stirring blade 25 while moving as indicated by a white arrow. When the sputum substrate 23 becomes a ball 39 in a state of being partially tightened by the engagement of the sputum hyphae, the spider ball 39 is crushed by stirring. Therefore, the agitation exhibits two important functions of agitating the straw substrate layer 24 to improve the air permeability and crushing the straw balls 39.

The cocoon substrate layer 24 is in a state in which the cocoon mycelia are engaged with each other and are integrally tightened, and by the rotation of the stirring blade 25, the surrounding cocoon substrate is pushed up and most of it is crushed. . However, a part of the straw substrate becomes a ball without being crushed.
This ball is mixed with the surrounding soot substrate in the lower layer portion of the soot substrate layer and uniformly crushed, but the balls generated in the upper layer portion (surface layer portion) are mixed with the stirring blade 25 and the surrounding soot substrate. Since it is rarely (or not) rubbed, it floats as it is on the surface.
If the balls that have floated on the surface layer are left without being ventilated, good quality cannot be obtained. In the past, this ball was crushed manually.

Therefore, in the present invention, an inclined plate 42 is attached to the elevating frame 26 (or a machine frame fixed to the side of the iron making tub), and the upper surface of the cocoon substrate layer 24 is leveled by the inclined plate 42, so 41 was crushed and crushed. Further, the balls generated in the upper layer part were eliminated by sandwiching them between the inclined plate 42, the stirring blade 25 and the surrounding soot substrate.
As a result, the balls 41 on the upper surface of the straw substrate layer 24 are not generated, and even if they are generated, the balls 41 can be finely crushed.

The angle θ of the inclined plate 42 with respect to the horizontal plane 43 will be described.
The cocoon balls 39 generated inside the cocoon substrate layer 24 are sandwiched between the surrounding cocoon substrate 23 and the stirring blades 25 and crushed. Therefore, the candy balls 41 existing on the upper surface of the candy substrate layer 24 are similarly crushed by being sandwiched between the surrounding candy substrate and the inclined plate 42.
If θ exceeds 60 °, the inclined plate 42 rises too much and the spear balls 41 are rather dammed up, and the crushing efficiency decreases. On the other hand, if [theta] is less than 20 [deg.], The inclined plate 42 is laid too much, and the height of the inclined plate 42 is reduced, and there is a possibility that the ball 41 will get over the inclined plate 42. It is necessary to make 42 larger.
In order to satisfy the two conditions of making the inclined plate 42 compact and improving the crushing efficiency, θ is set in the range of 20 ° to 60 °, preferably in the range of 30 ° to 45 °.

The inclined plate 42 is preferably a flat plate made of stainless steel. However, further results were obtained when the inclined plate 42 was changed to a mesh plate.
FIG. 3 is a perspective view showing an example in which an inclined plate is formed of a mesh plate, and shows that a horizontally long mesh plate 44 is attached to the lifting frame 26. The mesh plate 44 has an angle θ with respect to the horizontal plane 43 of 20 to 60 °, preferably 30 to 45 °, and one side W of the mesh is 1 to 5 cm, preferably 2 to 3 cm. The reason is as follows.

  The inclined mesh plate 44 is easy to catch the balls of the cocoons, and exerts an effect that it is very easily and finely crushed by the wire constituting the mesh. In addition, a part of the cocoon substrate passes through the mesh. At this time, if the size of the mesh opening is adjusted, the cocoon balls can be finely broken into a more preferable size.

If the mesh is less than 1 cm, particularly in the case of soy sauce cake, the straw substrate may adhere to the mesh or become clogged, and the function as the mesh plate may be lost. Alternatively, frequent cleaning is required. Moreover, when the mesh exceeds 5 cm, the function as a mesh plate is reduced, and it is difficult to obtain good quality from the soot substrate that has passed through the mesh.
In order to exhibit the original function of the mesh board and to maintain the quality of the soot substrate, it is effective to set the side of the mesh board in the range of 1 to 5 cm, preferably in the range of 2 to 3 cm.

(Experimental example)
Experimental examples according to the present invention will be described below. Note that the present invention is not limited to experimental examples.
FIG. 4 is a schematic view of the experimental apparatus. In the experimental apparatus, the vertical stirring blade 25 is a spiral blade having an outer diameter E = 20 cm and a length F = 62 cm, and the space between adjacent spiral blades is 2 cm. 32 are attached to the elevating frame 26 so as to be rotatable in a straight line in the direction of the front and back of the drawing, and slanted in the vicinity of the vertical stirring blade 25 (distance C = 7 cm between the outer periphery of the rotating shaft and the plate support rod). A plate 42 (width G = 26 cm) is provided with an inclination (inclination angle θ = 30 °), and the inclined plate 42 is in contact with the bottom surface of the soot substrate or is buried under the surface of the soot substrate (with respect to the bottom surface of the lifting frame 26). At the same time, the upper end of the distance B = 21 cm holds a height at which the soot substrate cannot get over (distance A with the lifting frame 26 = 8 cm).

  The inclined plate 42 was a flat plate without holes in Example 1, and a mesh plate having a mesh size of 2 cm in Example 2. In the comparative example, the inclined plate 42 was not used.

  Ingredients mixed with inoculated with soy sauce brewing seed gonococcus (mixed soy substrate) after mixing the mixed wheat with fried cracked wheat in the above-described experimental equipment and cooking the soy sauce raw material Was filled (filled) to a thickness of 50 cm, and the temperature-controlled and humidity-controlled air was continuously forced from the lower chamber of the breathable moving floor.

  At the 15th hour after the start of operation, the screw type stirrer was lowered, the screw was buried in the soot substrate and rotated, and the soot was stirred and maintained. For the maintenance, the position of the screw stirrer was not moved, and only the moving bed was slowly rotated once for about 50 minutes.

FIG. 5 is an explanatory diagram of the evaluation procedure of the experiment.
In (a), the soot substrate 23 is scooped up with a bucket 46 having a capacity of 20 liters from the soot substrate layer 24 (about 30 cm from the surface) immediately after the maintenance. The “total weight of the sample” is measured by subtracting the weight of the bucket 46 from the total weight.
In (b), the straw substrate 23 is placed on the sheet 47 from the bucket 46. This work was performed with care so that the ball 41 did not collapse.
As shown to (c), it isolate | separates into the candy ball 41 and the healthy candy substrate 23. FIG. Then, the weight of the ball 41 is measured.

  The above results are summarized in Table 1.

  In the comparative example, an experiment was performed using an experimental apparatus that does not include an inclined plate. The total amount of the sample was 9.02 kg, and the weight of the jade ball was 2.03 kg. The ball ratio (100 × ball weight ÷ total sample weight) is 23%.

  In Example 1, an experiment was performed using an experimental apparatus provided with a flat plate without holes as an inclined plate. The total amount of the sample was 6.95 kg, and the weight of the jade ball was 0.32 kg. The ratio of balls is 5%.

  In Example 2, an experiment was performed using an experimental apparatus including a 2 cm mesh screen as an inclined plate. The total amount of the sample was 6.83 kg, and the weight of the jade ball was 0.07 kg. The ratio of balls is 1%.

  The smaller the ball ratio, the better. Therefore, Example 2 can be evaluated as 、, Example 1 as ◯, and Comparative Example as ×.

  In the present invention, the koji substrate is a soy sauce koji substrate, but any type of koji substrate may be used as long as it is used for food, cosmetics, medical use, etc., such as a bran koji substrate, a rice koji substrate, or a wheat koji substrate.

  Moreover, although the specific example of the vertical stirrer has been described with the stirring blades, it may be a swirl stirrer manufactured by twisting a pin-type stirring shaft or a band plate in which a pin is planted on a rotating shaft, and its shape and structure Is optional.

  If the vertical stirrer is lowered only when necessary as in this embodiment to stir the soot substrate layer, the stirrer motor need only be supplied with power during agitation, thus saving electricity costs.

  Further, the inclined plate can move horizontally relative to the moving floor, that is, the moving plate may be moved (rotated) without moving the inclined plate as in the present embodiment. As a fixed air-permeable floor, the vertical stirrer and the inclined plate may be moved horizontally.

  The present invention is suitable for a koji making apparatus for soy sauce koji.
