TECHNICAL FIELD
[0001] The utility model relates to food processing equipment field, concretely is a kind of add koji device. BACKGROUND
[0002] In the brewing of food flavoring and wine, such as soy sauce and vinegar, koji culture is a very important process. During the feed culture stage of bran koji, koji is added to the cooked material after steaming and cooking to start and promote the growth and reproduction of Aspergillus.
[0003] However, koji itself has a certain amount of moisture, and when the moisture is too high, it can cause the koji to stick together and form a bridge structure, which can appear in the hopper and cannot be normally added to the cooked material. Therefore, during the koji adding process, workers often need to closely monitor the koji adding situation to ensure the continuous koji adding of the koji adding device.
[0004] At the same time, when the koji forms a bridge, it is difficult to ensure the amount of koji added to the cooked material by the koji adding device, which can cause uneven fermentation and affect product quality and yield. INVENTION CONTENTS
[0005] To solve the above problems, the utility model provides a koji adding device, which reduces the possibility of koji bridging in the hopper and affecting the koji adding process, and ensures that the koji adding device can stably and continuously add koji to the cooked material.
[0006] The present application provides a koji adding device, comprising: a rack; a driving part fixed in the rack; a hopper supported by the rack; a transmission structure connected to one end of the driving part and extending into the hopper through the bottom of the hopper; a stirring mechanism arranged in the hopper, the stirring mechanism being connected to the transmission structure, and the driving part driving the stirring mechanism to rotate through the transmission structure.
[0007] According to the technical scheme, when the koji adding device is running, the koji is stored in the hopper, and the stirring mechanism arranged in the hopper is driven to rotate by the driving part, so that the state of the koji in the hopper is stirred from a static state to a flowing state. Avoiding the koji from being in a static state for a long time, the koji between the koji is bonded together to form a bridge structure, which appears in the hopper and cannot be normally added to the cooked material. At the same time, the koji in the hopper is avoided from forming a bridge by driving the stirring mechanism to rotate by the driving part, which replaces manual monitoring of the koji adding device and ensures normal operation of the koji adding process.
[0008] In an optional technical solution, the hopper is in the shape of a cylinder.
[0009] According to the technical scheme, the whole hopper is cylindrically arranged, when the driving part drives the stirring mechanism to rotate, more koji in the hopper can be stirred into a flowing state, avoiding the occurrence of dead angles in the hopper which cannot be stirred, and the koji in the dead angles needs manual intervention or is stored in the dead angles of the hopper for a long time and cannot be automatically added to the clinker, causing the enzyme activity of the microorganisms in the koji to decrease and affecting the fermentation efficiency.
[0010] In an optional technical scheme, the stirring mechanism further comprises a rotating part connected with the transmission structure; a plurality of blades are fixedly connected at one end to the top of the rotating part and extended and bent to the bottom of the hopper at the other end.
[0011] According to the technical scheme, the stirring mechanism is composed of a rotating part and a plurality of blades fixedly connected to the top of the rotating part, the driving part drives the rotating part to rotate through the transmission structure, the rotating part drives the blades fixedly connected thereto to rotate, and the plurality of blades extended and bent to the bottom of the hopper increase the stirring range when the stirring mechanism rotates, so that more koji in the hopper can be stirred from a static state to a flowing state, avoiding the problem that the stirring mechanism is too small to make all the koji near the bottom of the hopper enter a flowing state, thus causing dead angles, and avoiding the problem that the stirring mechanism occupies a large space, thus causing the need to frequently add koji to the hopper.
[0012] In an optional technical scheme, the stirring mechanism further comprises a plurality of stirring blocks fixedly arranged in a one-to-one correspondence at one end of the plurality of blades near the bottom of the hopper.
[0013] According to the technical scheme, when the driving part drives the stirring mechanism to rotate, the rotating part drives the blades and the stirring blocks to rotate, and the stirring blocks arranged at one end of the blades near the bottom of the hopper can make the koji near the edge of the bottom of the hopper be stirred into a flowing state, avoiding the generation of dead angles, and at the same time, the stirring blocks arranged near the bottom of the hopper further push the koji in contact with the bottom of the hopper to flow during the stirring process, avoiding the generation of dead angles at the bottom of the hopper.
[0014] In an optional technical scheme, the koji adding device further comprises a discharge port arranged at the bottom of the hopper; and a koji adding pipeline connected with the hopper through the discharge port.
[0015] According to the technical scheme, the koji in the hopper is pushed to the discharge port arranged at the bottom of the hopper by gravity during the stirring process, enters the koji adding pipeline connected with the hopper through the discharge port, and is then added to the clinker through the koji adding pipeline. The stirring mechanism ensures that the koji is continuously stirred and pushed to the discharge port, realizing continuous and stable koji addition of the koji adding device.
[0016] In an optional technical scheme, the koji adding device further comprises a quantitative koji adding machine connected with the koji adding pipeline, and a narrow port section is formed at the connection.
[0017] According to this technical solution, by setting up a quantitative koji-adding machine, the amount of koji added by the koji-adding device can be further controlled, which makes it easier to adjust the amount of koji added according to the amount of cooked material, control the uniformity of koji addition, and thus improve the quality of the koji material cultivated.
[0018] In the optional technical solution, the top of the hopper is provided with a first cover and a second cover, one end of the first cover and one end of the second cover are fixedly connected, and the other end of the first cover and / or the other end of the second cover can be opened in the form of a flip cover.
[0019] According to the technical solution, by setting a first cover and a second cover, when it is necessary to add koji to the hopper, the first cover or the second cover can be opened in the form of a flip cover. This avoids the problem that the top cover of the hopper is too large and difficult to open, and also avoids the problem that the top cover of the hopper may be contaminated with bacteria when it is opened and placed, which may affect the koji cultivation.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Figure 1 This is a schematic diagram of the overall structure of the bending device 100 in the embodiments of this application, as shown below. Figure 1 As shown, the tumbling device 100 provided in this embodiment includes: a frame 101, a drive unit 102 fixed in the frame 101, and a hopper 103 supported by the frame 101. The hopper 103 and the drive unit 102 are connected by a transmission structure 104. One end of the transmission structure 104 is connected to the drive unit 102, and the other end extends into the hopper 103 through the bottom of the hopper 103 and is connected to a stirring mechanism 105 disposed inside the hopper 103. The drive unit 102 drives the stirring mechanism 105 to rotate inside the hopper 103 via the transmission structure 104.
[0024] The starter adding device 100 in the above embodiment of the present application stores a certain amount of starter in the hopper 103. When the starter adding device 100 is used, the driving part 102 drives the stirring mechanism 105 to continuously rotate in the hopper 103 via the transmission structure 104, so that the starter stored in the hopper 103 is stirred from the static state and kept in the flowing state. This avoids the phenomenon that the starter in the hopper 103 is in the static state for a long time due to higher moisture content and other reasons, which affects the normal work of the starter adding device 100 and causes the process of adding starter to clinker to be unable to proceed normally. The starter in the hopper 103 is always kept in the flowing state by the stirring mechanism 105, which ensures continuous and stable starter adding and guarantees the uniformity of the starter added to clinker, thereby improving the quality of the starter cultured. At the same time, the prior art cannot avoid the phenomenon that the starter in the hopper 103 appears bridging and cannot be discharged. When the starter adding device 100 is running, the staff often need to pay attention to the starter adding situation. The starter is kept in the flowing state by the rotation of the stirring mechanism 105 to ensure the normal operation of the starter adding process, which also avoids the waste of human resources.
[0025] Although Figure 1 The rack 101 is shown in the form of a rod structure jointed together, but the present application is not limited thereto. Other settings that can fix the driving part 102 in the rack 101 and support the hopper 103, such as a box body, etc., should be included in the protection scope of the present application.
[0026] As a preferred embodiment of the present application, the hopper 103 is in the overall cylindrical shape. The stirring mechanism 105 in the hopper 103 further includes a rotating part 1051 and a plurality of blades 1052 fixedly connected to the top of the rotating part 1051. The other end of the blade 1052 extends and bends to the bottom of the hopper 103. Preferably, the rotating part 1051 is arranged at the center position of the hopper 103, and the horizontal distance of the blade 1052 extending and bending is slightly smaller than the radius of the cylinder.
[0027] By arranging the plurality of blades 1052 fixedly connected to the top of the rotating part 1051 and extending and bending the other end of the blade 1052 to the bottom of the hopper 103, the contact area of the stirring mechanism 105 with the starter in the hopper 103 is reduced without affecting the stirring range of the stirring mechanism 105. This avoids the problem that the contact area with the starter is too large, which increases the rotating resistance of the stirring mechanism 105 and thus increases the energy consumption of the driving part 102. At the same time, the overall volume of the stirring mechanism 105 is also reduced, which avoids the problem that the stirring mechanism 105 occupies a large space in the hopper 103, resulting in that less starter can be stored in the hopper 103 and the starter needs to be frequently added to the hopper 103.
[0028] When the drive unit 102 drives the stirring mechanism 105 to rotate, multiple blades 1052 rotate around the rotating unit 1051 simultaneously. The rotation path of the blades 1052 is cylindrical and matches the shape of the hopper 103. At the same time, the radius of the cylindrical area formed by the rotation of the blades 1052 is slightly smaller than the radius of the hopper 103, which increases the stirring range when the stirring mechanism 105 rotates. This allows the seed culture stored in different positions in the hopper 103 to be in a flowing state under the push of the stirring mechanism 105, avoiding the problem that the stirring mechanism 105 is too small to allow all the seed culture near the bottom of the hopper 103 to enter a flowing state or that it cannot match the hopper 103, thus creating dead zones.
[0029] As a preferred embodiment of this application, each blade 1052 is also fixedly provided with a plurality of stirring blocks 1053 at one end near the bottom of the hopper 103, and preferably the bottom of each stirring block 1053 is in contact with the bottom of the hopper 103, and the radius of the stirring block 1053 is equal to the difference between the horizontal length of the blade 1052 and the radius of the hopper 103.
[0030] When the drive unit 102 drives the stirring mechanism 105 to rotate, multiple stirring blocks 1053 rotate together with the blades 1052. The stirring blocks 1053 push the starter culture near the bottom of the hopper 103 and the starter culture between the wall of the hopper 103 and the blades 1052 to be stirred into a flowing state. This avoids the formation of dead corners at the bottom or edge of the hopper 103 that cannot be stirred, which would cause some starter culture to be stored in the dead corners of the hopper 103 for a long time and not be automatically added to the cooked food. This would result in a decrease in the enzyme activity produced by the microorganisms in the starter culture and affect the fermentation efficiency.
[0031] It should be noted that this application does not limit the extension length of each blade 1052. The arrangement of multiple blades 1052 with the same extension length at different angles to simultaneously agitate the seed culture in the hopper 103, or the arrangement of multiple blades 1052 with different extension lengths at the same or different angles to agitate the seed culture in different areas of the hopper 103, should all be included within the scope of protection of this application.
[0032] Preferably, the koji-adding device 100 is further provided with a discharge port 1031 opening at the bottom of the hopper 103, and the koji-adding pipeline 106 is connected to the hopper 103 through the discharge port 1031.
[0033] When the koji-adding device 100 is running, the koji inside the hopper 103 is constantly in a flowing state due to the stirring mechanism 105. When the koji at the bottom of the hopper 103 is pushed to the discharge port 1031 by the stirring block 1053, it enters the koji-adding pipeline 106 under the action of gravity and is added to the clinker through the koji-adding pipeline 106. The stirring mechanism 105 ensures that the koji is continuously and stably pushed to the discharge port 1031, ensuring the uniformity of the koji added to the clinker. At the same time, the rotation of the stirring mechanism 105 and the action of gravity provide a driving force for the koji-adding process, improving the efficiency and stability of the koji-adding device 100.
[0034] Preferably, the koji-adding device 100 is further provided with a quantitative koji-adding machine 107 connected to the koji-adding pipeline 106, and a narrow section is formed at the connection between the quantitative koji-adding machine 107 and the koji-adding pipeline 106.
[0035] Through the above implementation method, after the starter culture enters the starter culture addition pipeline 106 under the pushing and gravity of the stirring mechanism 105, the quantitative starter culture addition machine 107 controls the amount of starter culture added to the clinker through the starter culture addition pipeline 106 according to the required proportion based on the clinker feed rate. When the clinker feed rate is large, the quantitative starter culture addition machine 107 is adjusted to allow more starter culture to be added to the clinker through the starter culture addition pipeline 106. When the clinker feed rate is small, the quantitative starter culture addition machine 107 is adjusted so that the starter culture entering the starter culture addition pipeline 106 from the discharge port 1031 is restricted by the narrow section and the quantitative starter culture addition machine 107, thereby reducing the amount of starter culture added to the clinker through the starter culture addition pipeline 106. This solves the problem that the amount of starter culture added cannot be adjusted according to the clinker feed rate due to relying solely on the pushing and gravity of the stirring mechanism 105 for starter culture addition.
[0036] As a preferred embodiment of this application, the top of the hopper 103 is also provided with a first cover 108 and a second cover 109, wherein one end of the first cover 108 is fixedly connected to one end of the second cover 109, and the other end of the first cover 108 and / or the other end of the second cover 109 can be opened in the form of a flip cover.
[0037] Through the above implementation method, when the amount of seed koji in the hopper 103 decreases and it is necessary to add seed koji to the hopper 103, the first cover 108 or the second cover 109 can be opened in the form of a flip cover. This avoids the problem that the top cover of the hopper 103 is too large and difficult to open. It also reduces the problem that the top cover of the hopper 103 may become contaminated with bacteria when adding seed koji to the hopper 103 when the top cover of the hopper 103 is a whole, which may affect the cultivation of the koji.
[0038] It should be noted that this application does not limit the specific connection method between the first cover 108 and / or the second cover 109 and the hopper 103. The first cover 108 (or the second cover 109) is fixedly connected to the hopper 103, the second cover 109 (or the first cover 108) can be opened in the form of a flip cover, or both the first cover 108 and the second cover 109 can be opened independently. All of these settings should be included within the protection scope of this application.
[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
