Description

Technical Field

[0001] The utility model relates to the field of food brewing, in particular to a disc koji making machine. Background Art

[0002] In the food brewing industry, the main purpose of koji making is to cultivate bacteria, let them grow and reproduce fully on the koji material, secrete a large number of enzymes, and provide the material basis for the decomposition, transformation and synthesis of raw materials in the fermentation process. The growth of bacteria needs to be carried out in a specific environment, such as ensuring a certain temperature, humidity and ventilation.

[0003] In the prior art, the koji material after steaming and sterilization is usually piled on the koji material culture bed in the koji material culture room for culture. During the culture process, as the mycelium grows, the moisture in the material will be consumed. At the same time, the growth of the mycelium will generate heat, which will increase the temperature of the koji material. In order to reduce the temperature of the material, it is necessary to ventilate and cool the material, remove carbon dioxide, and supply fresh oxygen, but ventilation will also take away the moisture in the koji material. In order to maintain the moisture of the koji material, the prior art often uses a humidifying spray device connected to the air inlet to mix water mist into the air so that the air entering the koji material culture room maintains a certain relative humidity.

[0004] However, during the cultivation process, as the mycelium grows, the koji material becomes tight, and the ventilation resistance increases. It is difficult for the humidified air to penetrate into the koji material, and the koji material needs to be turned over. When turning over the koji, the spores fly and are discharged from the air outlet, resulting in spore loss. In addition, since the air humidity after humidification is saturated, it cannot carry more water vapor, which reduces the cooling effect of the air on the inside of the koji material. Utility Model Content

[0005] The utility model aims to provide a disc koji making machine, which does not need to use saturated humidity air for humidification, can evenly humidify the inside of the koji material and reduce the flying of spore powder when turning the material.

[0006] The utility model provides a disc koji making machine comprising a koji material culture chamber, a disc culture bed, a koji turning device and a liquid spraying device.

[0007] The koji material cultivation chamber has an air inlet and an air outlet. The disc cultivation bed is arranged in the koji material cultivation chamber, and the upper surface of the disc cultivation bed is paved with koji material. The koji turning device is arranged above the disc cultivation bed and along the radial direction of the disc cultivation bed, and the lower end of the koji turning device extends into the koji material, and the koji turning device and the disc cultivation bed rotate relatively around the axis of the disc cultivation bed. The liquid spraying device is arranged above the disc cultivation bed and adjacent to the koji turning device.

[0008] According to the technical solution of the utility model, the disc culture bed and the bending device rotate relative to each other, including three situations: the disc culture bed is fixed and the bending device rotates around the axis of the disc culture bed; the disc culture bed rotates around the axis and the bending device is fixed; the disc culture bed rotates around the axis and the bending device rotates around the axis of the disc culture bed at a different rotation speed from that of the disc culture bed. At this time, the bending device can be extended into the curved material to perform bending, and the loose curved material facilitates air circulation to cool the curved material.

[0009] When the turning device turns the disc culture bed, the adjacent liquid spraying device can directly spray liquid onto the koji material during or after turning. The sprayed liquid can quickly penetrate into the loose koji material, and there is no need to supply saturated humidity air to humidify the koji material, so that the air humidity entering the koji material culture room through the air inlet will not be too high, and the heat dissipation effect can be increased by taking away the water vapor on the surface of the koji material.

[0010] In addition, by spraying liquid (water or nutrient solution) to humidify the inside of the koji material and supplement nutrients, the moisture and nutrients required for the growth of fine bacteria can be better met, and the flying of spores when turning the koji can be reduced, and most of the spores can be recovered.

[0011] As a preferred technical solution, the disc koji making machine also includes a lifting device, which is connected to the koji turning device and is used to drive the koji turning device to rise to a first position or descend to a second position. In the first position, the koji turning device is arranged without contact with the koji material. In the second position, the lower end of the koji turning device extends into the koji material.

[0012] According to the preferred technical solution, by controlling the lifting device, the bending device can be maintained in the first position where it does not contact the bent material when bending is not needed, and will not affect the uniform distribution of the bent material on the disc culture bed.

[0013] As a preferred technical solution, the disc koji making machine also includes a central axis and a driving device. The central axis is vertically fixed in the koji material culture chamber and passes through the axis position of the disc culture bed. The driving device is arranged corresponding to the periphery of the disc culture bed to drive the disc culture bed to rotate around the central axis.

[0014] According to the preferred technical solution, compared with the suspended liquid spraying device and the turning device, the disc culture bed has higher stability in rotating around the axis, and the disc culture bed is driven to rotate around the central axis by the driving device, so the liquid spraying device and the turning device do not need to move for spraying, and the disc culture bed can complete the turning of all the koji materials after one rotation, and the liquid spraying of the liquid spraying device is also more uniform.

[0015] As a preferred technical solution, the liquid spraying device comprises: a fixed rod and a plurality of liquid spraying heads, wherein the fixed rod is arranged along the radial direction of the disc culture bed, and the plurality of liquid spraying heads are arranged uniformly on the bottom surface or side surface of the fixed rod along the length direction of the fixed rod.

[0016] According to the preferred technical solution, multiple spray heads can spray liquid downward, and the liquid sprayed by the spray heads can cover a fan-shaped range. Therefore, by evenly arranging the spray heads on the fixed rods arranged along the radial direction, when the disc culture bed rotates, the liquid sprayed by the spray heads can evenly cover the curved material on the surface of the disc culture bed.

[0017] As a preferred technical solution, the liquid flow rate of the multiple liquid spray heads gradually increases radially outward from the axis of the disc culture bed.

[0018] According to the preferred technical solution, a plurality of spray heads are arranged along the radial direction of the circular culture bed. When the circular culture bed rotates, the linear velocity of the spray head close to the axis of the circular culture bed is smaller than the linear velocity of the spray head on the outside away from the axis of the circular culture bed. Therefore, the liquid flow rate of the plurality of spray heads is gradually increased from the axis of the circular culture bed radially outward, so that the liquid sprayed onto the curved material on the surface of the circular culture bed can be uniform inside and outside.

[0019] As a preferred technical solution, the fixed rod is connected to the lifting device, and the bending device includes a plurality of rotary augers, which are evenly arranged on the bottom surface of the fixed rod along the length direction of the fixed rod.

[0020] According to the preferred technical solution, the material is turned by rotating the auger, so that the taut curved material can be transported upward from the lower layer and stirred.

[0021] As a preferred technical solution, the front side surface of the fixed rod is opposite to the rotation direction of the disc culture bed, and the rear side surface of the fixed rod is opposite to the front side surface. Multiple spray heads are arranged on the rear side surface of the fixed rod. Therefore, when the disc culture bed rotates to the rotary auger, the koji material is sent into the rotary auger for turning over. At the same time, the multiple spray heads of the spray device lag slightly behind the rotary auger to spray fan-shaped liquid onto the koji material that has just been turned over, so that the sprayed liquid can fall into the internal koji material exposed after turning over, avoiding the sprayed liquid from falling directly on the surface of the koji material that has not yet been turned over, thereby evenly humidifying the koji material.

[0022] As a preferred technical solution, the turning device is a rotary turning harrow, and the end of the shaft of the rotary turning harrow is rotatably connected to the lifting device.

[0023] According to the preferred technical solution, when the rotary rake is used for turning the bent material, the rake plates of the rotary rake are buried in the bent material, the shaft rotates and drives the rake plates to rotate, the bent material is continuously fed between the rake plates, and the taut bent material is transported from the upper layer downward and stirred.

[0024] As a preferred technical solution, the disc culture bed divides the koji culture chamber into an upper chamber and a lower chamber, and the air inlet and the air outlet are respectively opened in the upper chamber and the lower chamber.

[0025] According to the preferred technical solution, the air inlet and the air outlet are respectively arranged in the upper chamber and the lower chamber on both sides of the disc culture bed, so that the air enters from one side of the disc culture bed and is blown out from the other side, the contact area with the bent material on the disc culture bed is larger, and the heat dissipation effect is good.

[0026] As a preferred technical solution, the disc culture bed is horizontally arranged in the center of the koji material culture chamber, and the side of the disc culture bed is arranged in contact with the inner wall of the koji material culture chamber.

[0027] According to the preferred technical solution, the disc culture bed is horizontally arranged and the side of the Ajin disc culture bed is in contact with the inner wall of the koji material culture chamber, so that after the air enters from one side of the disc culture bed, it must pass through the disc culture bed and then be blown out from the air outlet, so that it can better contact the inside of the koji material to take away the heat inside the koji material.

Therefore, it cannot be understood as a limitation on the present invention.

[0038] First embodiment

[0039] Figure 1 This is a schematic diagram of the overall structure of a disc koji making machine provided by the first embodiment of the utility model. Figure 1 As shown, the disc koji making machine includes a koji material cultivation chamber 1, a disc cultivation bed 2, a koji turning device 3 and a liquid spraying device 4.

[0040] The koji material culture chamber 1 may be a heat preservation chamber with an air inlet 11 and an air outlet 12, which is used to culture the fine bacteria in the koji material 100 at a constant temperature. The positions of the air inlet 11 and the air outlet 12 are not limited, and are preferably arranged on opposite sides of the koji material culture chamber 1, so that the interior of the koji material culture chamber 1 can be better ventilated.

[0041] The disc culture bed 2 is arranged in the koji material culture chamber 1. The upper surface of the disc culture bed 2 is paved with koji material 100. The fine bacteria can grow in the koji material 100 laid on the surface of the disc culture bed 2. The disc culture bed 2 can be composed of a mesh plate, which has a good ventilation effect and allows air to directly pass through the disc culture bed 2 to ventilate and dissipate the koji material 100 laid on the disc culture bed 2. The disc culture bed 2 can be arranged in the koji material culture chamber 1 at any angle.

[0042] Generally speaking, the disc culture bed 2 is preferably arranged in the koji material culture chamber 1 in a horizontal or slightly inclined manner, so that the space inside the koji material culture chamber 1 is divided by the disc culture bed 2 to form an upper chamber 13 and a lower chamber 14, and the air inlet 11 and the air outlet 12 are respectively opened in the upper chamber 13 and the lower chamber 14, so that the air enters from one side of the disc culture bed 2 and is blown out from the other side, and the contact area with the koji material 100 on the disc culture bed 2 is larger, and the heat dissipation effect is good. Preferably, the air inlet 11 is arranged in the lower chamber 14, and the air outlet 12 is arranged in the upper chamber 13, so that after the cold air enters from the lower side of the disc culture bed 2, the hot air after absorbing heat passes through the disc culture bed 2 and rises, and then blows out from the air outlet 12, which can better take away the heat generated by the fine bacteria in the koji material 100 during the growth process.

[0043] Further preferably, the disc culture bed 2 is horizontally arranged in the koji material culture chamber 1, and the side of the disc culture bed 2 is arranged in close contact with the inner wall of the koji material culture chamber 1. The disc culture bed 2 is arranged horizontally and the side of the disc culture bed 2 is in close contact with the inner wall of the koji material culture chamber 1, so that after the air enters from one side of the disc culture bed 2, it must pass through the disc culture bed 2 and then be blown out from the air outlet 12, so that it can better contact with the inside of the koji material 100 to take away the heat inside the koji material 100.

[0044] The bending device 3 is disposed above the disc culture bed 2 and along the radial direction of the disc culture bed 2 . The type of the bending device 3 is not limited. Figure 2 FIG. 3 shows a case where the bending device 3 is formed into a plurality of rotating augers 31. Figure 1 and Figure 2 The multiple rotary augers 31 shown are used as an example for explanation. The multiple rotary augers 31 are evenly arranged on the bottom surface of the fixed rod 42 along the length direction of the fixed rod 42. When the bent material 100 is turned over, the rotary augers 31 are buried in the bent material 100. By driving the rotary augers 31 to rotate, the taut bent material 100 can be transported and stirred from the lower layer upward, so that the bent material 100 on the surface of the disc culture bed 2 can be turned over evenly up and down.

[0045] In particular, in this embodiment, the disc culture bed 2 and the bending device 3 can rotate relative to each other, so that the bending device 3 can extend into the bent material 100 on the surface of the disc culture bed 2 to perform bending, which can loosen all the bent material 100 on the surface of the disc culture bed 2 and facilitate air circulation to cool the bent material 100.

[0046] Specifically, the relative rotation of the disc culture bed 2 and the bending device 3 may include three situations: the disc culture bed 2 is fixed, and the bending device 3 rotates around the axis of the disc culture bed 2; the disc culture bed 2 rotates around the axis, and the bending device 3 is fixed; the disc culture bed 2 rotates around the axis, and the bending device 3 rotates around the axis of the disc culture bed 2 at a different rotation speed than the disc culture bed 2. In the above three situations, Figure 1 and Figure 3 From the perspective of the preferred embodiment, a central axis 5 is provided at the axial position of the disc culture bed 2, and the disc culture bed 2 is sleeved on the central axis 5, and a driving device 7 is provided corresponding to the outer circumference of the disc culture bed. The driving device 7 may include a driving wheel, and the rotating surface of the driving wheel is provided in contact with the disc culture bed 2, so that the driving device 7 drives the driving wheel to rotate, and the disc culture bed 2 can be driven to rotate stably around the central axis 5. Since the disc culture bed 2 rotates, the turning device 3 can turn over all the bent materials 100 on the surface of the disc culture bed 2 while remaining stationary, thereby ensuring that the relative rotational motion between the turning device 3 and the disc culture bed 2 is stable, and the material can be continuously fed into the turning device 3.

[0047] The liquid spraying device 4 may include a liquid spraying head 43 and a liquid supply mechanism 41 which are connected. The liquid supply mechanism 41 may store water or nutrient solution, and the liquid spraying head 43 is disposed above the disc culture bed 2 and adjacent to the bending device 3, and can spray water or nutrient solution onto the surface of the koji material 100 during or after bending by the bending device 3, so that the sprayed liquid can quickly penetrate into the koji material. In particular, in the case of spraying water, a sterilizing and filtering mechanism 44 may be disposed between the liquid spraying head 43 and the liquid supply mechanism 41 to remove impurities and bacteria in the water and avoid contamination of fine bacteria in the koji material 100.

[0048] In some preferred embodiments, the liquid spraying device 4 may further include a fixed rod 42 arranged along the radial direction of the disc culture bed 2, and a plurality of liquid spraying heads 43 are evenly arranged on the bottom or side of the fixed rod 42, and spray liquid downwardly, and the liquid sprayed by the liquid spraying head 43 can cover a fan-shaped range, so that by evenly arranging the liquid spraying heads 43 on the fixed rod 42 arranged along the radial direction, when the disc culture bed 2 and the bending device 3 rotate relative to each other, the liquid sprayed by the liquid spraying head 43 can evenly cover the bent material 100 on the surface of the disc culture bed 2.

[0049] Furthermore, the liquid flow rate of the multiple liquid spray heads 43 can be gradually increased from the axis of the disc culture bed 2 along the radial direction outward. The multiple liquid spray heads 43 are arranged along the radial direction of the disc culture bed 2. When the disc culture bed 2 and the bending device 3 rotate relative to each other, the linear velocity of the liquid spray heads 43 close to the axis of the disc culture bed 2 is less than the linear velocity of the liquid spray heads 43 far from the axis of the disc culture bed 2. Therefore, the liquid flow rate of the multiple liquid spray heads 43 is gradually increased from the axis of the disc culture bed 2 along the radial direction outward, so that the liquid sprayed onto the bending material 100 on the surface of the disc culture bed 2 can be uniform inside and outside.

[0050] In this embodiment, when the turning device 3 turns the disc culture bed 2, the adjacent liquid spraying device 4 can directly spray liquid to the koji material 100 during or after turning, and the sprayed liquid can quickly penetrate into the loose koji material 100, and there is no need to supply saturated air for humidification, so that the humidity of the air entering the koji material culture chamber 1 through the air inlet 11 will not be too high, and the heat dissipation effect can be increased by taking away the water vapor on the surface of the koji material 100. In addition, by spraying liquid (water or nutrient solution) to humidify the inside of the koji material 100 and supplement nutrients, the water and nutrition required for the growth of fine bacteria can be better met, and the flying of spore powder during turning can be reduced, and most of the spore powder can be recovered.

[0051] In other optional embodiments, the disc koji making machine may further include a lifting device 6, and the turning device 3 may be connected to the lifting device 6 and rise or fall under the drive of the lifting device 6. Specifically, in this embodiment, both ends of the fixed rod 42 may be installed on the lifting device 6, and the lifting device 6 may drive the fixed rod 42 to drive the rotating auger 31 to rise to a first position or fall to a second position. In the first position, the rotating auger 31 is arranged without contact with the koji material 100, and in the second position, the rotating auger 31 is buried in the koji material 100. By controlling the lifting device 6, when turning the koji material is not required, the rotating auger 31 can be maintained in the first position without contact with the koji material 100, which will not affect the uniform distribution of the koji material 100 on the disc culture bed 2.

[0052] Figure 3 1 is a top view of the disc koji making machine in this embodiment. Figure 2 and Figure 3From the perspective of the disc koji making machine, when the disc koji making machine rotates counterclockwise, the front side 421 of the fixed rod 42 is opposite to the rotation direction of the disc culture bed 2. At this time, since the bending device 3 is arranged at the bottom of the fixed rod 42, the front side 421 will overlap with the material that has not been bent, and the rear side 422 will follow the bending device 3. In this embodiment, a plurality of liquid spray heads 43 can be arranged on the front side 421 and the rear side 422 of the fixed rod 42, or, as a preference, a plurality of liquid spray heads 43 can be arranged on the rear side 422 of the fixed rod 42, so as to spray fan-shaped liquid to the koji material 100 that has just been turned, so as to make the sprayed liquid fall into the internal koji material 100 exposed after bending, so as to avoid the sprayed liquid directly falling on the surface of the koji material 100 that has not been bent, and to humidify the koji material 100 more deeply and evenly.

[0053] In this embodiment, a disc culture bed 2 is provided in the koji material culture chamber 1, and the disc culture bed 2 rotates around the central axis 5. The koji material culture chamber 1 is divided into an upper chamber 13 and a lower chamber 14 by the disc culture bed 2. The air entering the lower chamber 14 through the air inlet 11 passes through the koji 100 on the disc culture bed 2 and flows into the upper chamber 13, and is then blown out through the air outlet 12. The air can dissipate heat and ventilate the interior of the koji material 100 to cultivate fine bacteria.

[0054] When turning the koji, the lifting device 6 is controlled to drive the fixed rod 42 downward, so that the rotating auger 31 at the bottom of the fixed rod 42 is buried in the koji material 100, and at the same time, the central shaft 5 is driven to drive the disc culture bed 2 to rotate. In this way, the koji material 100 is continuously fed into the rotating auger 31, and the taut koji material 100 is transported and stirred from the lower layer upward. At the same time, the liquid spray head 43 of the liquid spray device 4 sprays fan-shaped liquid, and the disc culture bed 2 rotates one circle, and the turning and humidification of all the koji materials 100 on the surface of the disc culture bed 2 can be completed.

[0055] Second embodiment

[0056] Figure 4 It is a schematic diagram of the overall structure of another disc koji making machine provided by the second embodiment of the utility model. Figure 5 1 is a schematic diagram of the structure of the turning device 3 of the disc koji making machine provided in the second embodiment of the utility model. Compared with the first embodiment, the second embodiment of the utility model provides a disc koji making machine with a rotating turning rake 32 as the turning device 3, and the same structure as the disc koji making machine provided in the first embodiment is not repeated here.

[0057] Combination Figure 4 and Figure 5In this embodiment, the turning device 3 is a rotary turning rake 32, and the rotary turning rake 32 includes a shaft 321 and a rake plate 322 fixed to the surface of the shaft 321. Different from the turning device 3 in the disc koji making machine in the first embodiment, the turning device 3 and the liquid spraying device 4 in this embodiment are separately arranged, the rotary turning rake 32 is arranged below the fixed rod 42 of the liquid spraying device 4, and the end of the shaft 321 is rotatably connected to the lifting device 6.

[0058] In this embodiment, a disc culture bed 2 is provided in the koji material culture chamber 1, and the disc culture bed 2 rotates around the central axis 5. The koji material culture chamber 1 is divided into an upper chamber 13 and a lower chamber 14 by the disc culture bed 2. The air entering the lower chamber 14 through the air inlet 11 passes through the koji 100 on the disc culture bed 2 and flows into the upper chamber 13, and is then blown out through the air outlet 12. The air can dissipate heat and ventilate the interior of the koji material 100 to cultivate fine bacteria.

[0059] When turning the koji, the lifting device 6 is controlled to drive the fixed rod 42 and the rotary turning rake 32 to descend, so that the rake plate 322 of the rotary turning rake 32 is buried in the koji material 100, and the shaft 321 is driven to drive the rake plate 322 to rotate, and at the same time, the central shaft 5 is driven to drive the disc culture bed 2 to rotate. Thus, the koji material 100 is continuously fed between the rake plates 322, and the taut koji material 100 is transported downward from the upper layer and stirred. At the same time, the spray head 43 of the spray device 4 sprays fan-shaped liquid, and the disc culture bed 2 rotates one circle, and the turning and humidification of all the koji materials 100 on the surface of the disc culture bed 2 can be completed.
