Description

Technical Field

[0001] This application belongs to the field of soy sauce production technology, and in particular relates to a legume cooling device for soy sauce production. Background Technology

[0002] Soy sauce is a condiment made by fermenting soybeans, wheat (or other grains), salt and microorganisms (such as Aspergillus oryzae). Soybeans are the main material for soy sauce production. In the pretreatment of raw materials, soybeans must first be steamed at high temperature. After being steamed at high temperature, the soybeans need to be cooled before they can be transported to the koji-making process.

[0003] The current cooling method generally involves letting soybeans cool naturally, but this method is slow and not conducive to improving the efficiency of soy sauce production. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a legume cooling device for soy sauce production, which can effectively improve the cooling speed of soybeans.

[0005] To achieve the above objectives, the present invention employs the following technology:

[0006] The substrate is horizontally positioned, and a horizontally positioned mounting rod is mounted on top of it.

[0007] The support plate is rotatably connected to the mounting rod, and its rotation axis is set parallel to the support plate.

[0008] The cooling tank is mounted parallel to the support plate and rotates around its own axis. One end of the cooling tank is open and contains a pair of parallel ventilation mesh plates facing the axis of the cooling tank. The two sides of the ventilation mesh plates are connected to the inner wall of the cooling tank, and the two ends of the ventilation mesh plates abut against the two end faces of the cooling tank. A feed inlet is opened on the wall of the cooling tank and is located between the two ventilation mesh plates.

[0009] Two ventilation openings are located on the wall of the cooling tank and are positioned opposite each other, with each opening facing the opposite side of the two ventilation mesh panels; each ventilation opening is equipped with an air supply mechanism and an air exhaust mechanism.

[0010] A cover plate is located at one end of the cooling tank and is movable along the axis of the cooling tank. It is used to block the opening of the cooling tank. The cover plate is rotated synchronously with the cooling tank. A sealing plate facing the axis of the cooling tank is provided on the outer edge of the cover plate. It is used to open or close the feed port as the cover plate moves.

[0011] The beneficial effects of this utility model are as follows:

[0012] By rotating the cooling tank and cooperating with the ventilation mesh, the soybeans are constantly turned over. At the same time, the air supply mechanism blows air into the cooling tank. The airflow blows onto the soybeans through the ventilation mesh. The turned soybeans have a large contact area with the airflow, which can effectively remove the heat from the soybeans. The exhaust mechanism can simultaneously discharge the hot airflow generated in the cooling tank, forming an airflow path, thereby achieving rapid cooling of the soybeans.

Detailed Implementation

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] This application provides a legume cooling device for soy sauce production, used to cool cooked soybeans, such as... Figures 1-4 As shown, it includes: substrate 1, support plate 2, cooling tank 3, two vents 4, cover plate 5, etc.

[0021] Among them, such as Figure 1 and Figure 2As shown, the substrate 1 is horizontally arranged, and a pair of columns 12 are vertically arranged on the substrate 1. The upper end of the columns 12 is connected to a horizontally arranged mounting rod 11, and the axes of the two mounting rods 11 coincide and are arranged opposite each other.

[0022] like Figure 1 , Figure 2 , Figure 5 As shown, the two sides of one end of the bearing plate 2 are rotatably connected to the corresponding mounting rod 11, and its rotation axis is set parallel to the bearing plate 2. A support plate 28 is vertically provided on the bearing plate 2, and a mating shaft 29 facing the length direction of the bearing plate 2 is connected to the upper end of the support plate 28.

[0023] like Figures 1-3 As shown, the cooling barrel 3 is cylindrical, with one end open and the other end rotatably connected to the mating shaft 29. Its rotation axis is parallel to the bearing plate 2 and coaxial with the axis of the cooling barrel 3. Inside the cooling barrel 3, there is a pair of ventilation mesh plates 31 that are parallel to each other and face the axis of the cooling barrel 3. The two sides of the ventilation mesh plates 31 are connected to the inner wall of the cooling barrel 3, and the two ends of the ventilation mesh plates 31 abut against the two end faces of the cooling barrel 3. The size of the mesh holes of the ventilation mesh plates 31 is smaller than the size of soybeans. A feed inlet 32 ​​is opened on the barrel wall of the cooling barrel 3, which is located between the two ventilation mesh plates 31.

[0024] like Figures 1-3 As shown, two vents 4 are opened on the wall of the cooling tank 3 and are arranged opposite each other. The two vents 4 are respectively arranged facing the two ventilation mesh plates 31 with their backs to each other. The two vents 4 are respectively provided with an air supply mechanism 41 and an air exhaust mechanism 42. The air supply mechanism 41 is used to supply air into the cooling tank 3, and the air exhaust mechanism 42 is used to exhaust the hot air flow in the cooling tank 3.

[0025] like Figure 1 and Figure 2 As shown, the cover plate 5 is circular and is located at one end of the cooling tank 3. It is movable along the axis of the cooling tank 3 to block the opening of the cooling tank 3. The cover plate 5 rotates synchronously with the cooling tank 3. The outer edge of the cover plate 5 is provided with a sealing plate 51 facing the axis of the cooling tank 3. When the cover plate 5 abuts against the opening end face of the cooling tank 3, the sealing plate 51 closes the feed inlet 32. When the cover plate 5 abuts against the opening end face of the cooling tank 3, the sealing plate 51 opens the feed inlet 32.

[0026] When applying, such as Figures 1-3As shown, the cooling device is located below the soybean cooking tank. After cooking, the support plate 2 is rotated towards the cooking tank so that the opening end of the cooling tank 3 faces upward at an angle, and the cover plate 5 is separated from the opening end face of the cooling tank 3 by a predetermined distance. At this time, the feed port 32 is fully open and located below the discharge port of the cooking tank. The cooking tank discharges soybeans into the cooling tank 3 through the discharge port. Since the cover plate 5 is separated from the opening end face of the cooling tank 3 at this time, the inclined cooling tank 3 can guide the soybeans to the other end of the cooling tank 3, which can effectively avoid the problem of soybeans accumulating and rolling out from the opening end of the cooling tank 3.

[0027] like Figures 1-3 As shown, after the cooking tank is discharged, the cover plate 5 is moved to abut against the open end face of the cooling tank 3. At the same time, the sealing plate 51 closes the feed inlet 32 ​​as the cover plate 5 moves. At this time, the bearing plate 2 rotates downwards until the open end of the cooling tank 3 faces diagonally downwards, so that the soybeans piled at the other end of the cooling tank 3 move along the inner wall of the cooling tank 3 towards the open end, thereby making the soybeans evenly distributed and improving the uniformity of subsequent soybean turning.

[0028] like Figures 1-3 As shown, after the soybeans are evenly distributed, the supporting plate 2 rotates to a horizontal position, and the cover plate 5 rotates synchronously with the cooling tank 3. Simultaneously, the air supply mechanism 41 blows air into the cooling tank 3, and the exhaust mechanism 42 discharges the hot airflow from the cooling tank 3. With the rotation of the cooling tank 3 and in conjunction with the ventilation mesh 31, the soybeans continuously tumble. The air blown in by the air supply mechanism 41 passes through the ventilation mesh 31 and is directed towards the soybeans. During tumbling, the soybeans have a large contact area with the airflow, effectively carrying away their heat. Simultaneously, the exhaust mechanism 42 discharges the hot airflow generated within the cooling tank 3, forming an airflow path that continuously carries away the heat from the soybeans, thus achieving a rapid cooling effect. During the tumbling process, if the soybeans are unevenly distributed, the tilt angle of the supporting plate 2 can be adjusted in real time to ensure even tumbling.

[0029] like Figures 1-3 As shown, after the soybeans are cooled to a predetermined temperature, the support plate 2 rotates downwards, causing the opening of the cooling tank 3 to face diagonally downwards. The cover plate 5 separates from the opening of the cooling tank 3, and the soybeans are poured out of the opening onto the conveyor belt and transported to the koji-making process. The above operation is repeated to cool the next batch of soybeans.

[0030] like Figure 1 and Figure 2 As shown, the integrated design of the sealing plate 51 and the cover plate 5, along with the rotation of the bearing plate 2, not only enables stable feeding of soybeans, but also allows the opening and closing of the feed inlet 32 ​​while the cover plate 5 opens and closes one end of the cooling tank 3. This eliminates the need for a separate drive structure to drive the sealing plate 51, resulting in lower production costs for the cooling equipment.

[0031] Specifically, such as Figures 1-4As shown, a portal frame 21 is mounted on the support plate 2 and located at one end of the cooling tank 3. The portal frame 21 is movable along the axis of the cooling tank 3. A first motor 22 is fixedly mounted on the top of the portal frame 21, and its driving end is coaxial with the cooling tank 3 and connected to one side of the cover plate 5. A pair of sliding rods 23 facing the axis of the cooling tank 3 are mounted on the support plate 2. The two sides of the portal frame 21 slide through the corresponding sliding rods 23. The lower ends of the two sides of the portal frame 21 are connected to racks 24 facing the axis of the cooling tank 3. Correspondingly, two sets of rack frames 241 are also provided on the support plate 2. The two racks 24 slide and engage with the corresponding rack frames 241 along the length of the support plate 2. A rotating rod 25 is mounted parallel to the support plate 2. A rotating seat 6 is fixed on one side of the support plate 2, and a second motor 27 is fixed on the other side. One end of the rotating rod 25 is rotatably connected to the rotating seat 6, and the other end is coaxially connected to the driving end of the second motor 27. Two gears 26 are coaxially mounted on the rotating rod 25, which are used to mesh with the corresponding racks 24. The use of a gear and rack structure in conjunction with a second motor 27 can effectively realize the movement of the cover plate 5. At the same time, the gear and rack structure has high transmission efficiency and stability, which can effectively ensure the stability of the movement of the cover plate 5.

[0032] When the cooling tank 3 rotates around its own axis, the cover plate 5 needs to keep one end of the cooling tank 3 closed at all times. That is, the structure that drives the cover plate 5 to move must have a self-locking requirement. Accordingly, the second motor 27 should be selected with a self-locking function, such as a motor with an electromagnetic brake.

[0033] Correspondingly, such as Figure 1 and Figure 2 As shown, the support plate 2 below the opening end of the cooling tank 3 has a hollow area, the gantry frame 21 is mounted above the hollow area, and the rack 24 is located on both sides of the hollow area. When the cooling tank 3 is unloading, its opening end is located above the hollow area, and soybeans can be directly poured into the conveyor belt through the hollow area. This can effectively avoid the problem of the unloading being affected by the unreasonable setting of the drive structure of the cover plate 5.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, two guide rods 52 are vertically arranged on one side of the cover plate 5. The guide rods 52 slide along the axis of the cooling barrel 3 and pass through its opening end face. The two guide rods 52 are arranged in a circular array along the opening end, and the plane formed by the axes of the two guide rods 52 is perpendicular to the ventilation mesh plate 31. When pouring, the first motor 22 drives the two ventilation mesh plates 31 to a vertical state, and the soybeans accumulate on the inner wall of the cooling barrel 3. The two guide rods 52 are located on opposite sides of the two ventilation mesh plates 31. When the soybeans slide out from the opening end, the guide rods 52 will not block the soybeans, which can effectively improve the pouring efficiency.

[0035] Specifically, such as Figure 3As shown, each ventilation opening 4 is provided with a support frame 43. The air supply mechanism 41 includes an air supply fan 44 provided on the support frame 43 in the corresponding ventilation opening 4. The exhaust mechanism 42 includes an exhaust fan 45 provided on the support frame 43 in the corresponding ventilation opening 4. Each of the two support frames 43 is provided with a third motor 46 for driving the air supply fan 44 and the exhaust fan 45 to rotate.

[0036] Correspondingly, a slip ring structure can be used to power the third motor 45. Specifically, the slip ring can be coaxially mounted on the mating shaft 29, the motor connection line is led out from the slip ring rotor and connected to the third motor 45, and the power connection line is led out from the slip ring stator and connected to the power supply. With the above structural setup, the problem of the connection line getting tangled due to the rotation of the cooling tank 3 can be effectively avoided.

[0037] Preferably, a corresponding support structure can be set on the bearing plate 2 to further support the cooling tank 3 and ensure its rotational stability.

[0038] Preferred, such as Figure 1 As shown, a linear mechanism 7 can be fixedly installed at one end of the base plate 1, with its movable end facing the length direction of the support plate 2 and rotatably connected to one end of a connecting plate 71. The other end of the connecting plate 71 is rotatably connected to the bottom of the support plate 2. The rotation axes corresponding to both ends of the connecting plate 71 are both oriented towards the width direction of the support plate 2. The tilt angle of the support plate 2 can be adjusted by the telescopic cooperation of the linear mechanism 7 with the connecting plate 71. The linear mechanism 7 can be in the form of a linear cylinder, hydraulic cylinder, etc.

[0039] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
