Description

Technical Field

[0001] This utility model relates to the field of koji-making technology, and in particular to a pressing device, a koji-making machine, and koji-making equipment. Background Technology

[0002] In solid-state fermentation, especially in alcoholic beverage brewing, yeast starter blocks play a crucial role. They are block-shaped substances made from various grains, such as wheat, barley, and peas, which are crushed, mixed, and processed through a series of specific techniques. This specially structured substance is rich in microorganisms and enzymes essential for the fermentation process, working together as important catalysts to promote the fermentation reaction. Traditionally, yeast starter blocks are made by manual pressing, most commonly by foot. However, this traditional pressing method applies pressure in only one direction, a unidirectional pressing technique. Because pressure is applied in only one direction, this method makes it difficult to ensure a uniform density within the yeast starter block, and also fails to guarantee ideal fermentation results. Furthermore, this method is not only labor-intensive but also relatively inefficient, hindering large-scale production. Therefore, improving production efficiency while ensuring the quality of yeast starter blocks has become a problem that needs to be solved. Utility Model Content

Subsequently, the koji-making material box is conveyed to the second position of the frame, where a pressing and pulp extraction mechanism presses the second side of the koji material, further completing the pulp extraction process to form the final koji block. Furthermore, a position detection mechanism intelligently detects the status of the first and second positions, issuing a signal when a koji-making material box is detected at the corresponding position. The control mechanism then precisely controls the workflow of each component based on these signals. This design ensures that the koji material is subjected to uniform pressure in both directions, guaranteeing consistent density within the koji block and significantly improving the pulp extraction effect. Compared to traditional unidirectional pressing, this method improves the quality of the koji blocks while increasing production efficiency, making large-scale, high-quality koji block production possible. Automated control reduces manual intervention, enhancing production stability and reliability. Attached Figure Description

[0054] In solid-state fermentation, especially in alcoholic beverage brewing, yeast starter blocks play a crucial role. They are block-shaped substances made from various grains, such as wheat, barley, and peas, which are crushed, mixed, and processed through a series of specific techniques. This specially structured substance is rich in microorganisms and enzymes essential for the fermentation process, working together as important catalysts to promote the fermentation reaction. Traditionally, yeast starter blocks are made by manual pressing, most commonly by foot. However, this traditional pressing method applies pressure in only one direction, a unidirectional pressing technique. Because pressure is applied in only one direction, this method makes it difficult to ensure a uniform density within the yeast starter block, and also fails to guarantee ideal fermentation results. Furthermore, this method is not only labor-intensive but also relatively inefficient, hindering large-scale production. Therefore, improving production efficiency while ensuring the quality of yeast starter blocks has become a problem that needs to be solved.

[0055] Therefore, this utility model proposes a pressing device 3, which aims to improve production efficiency while ensuring the quality of the yeast blocks.

[0056] Please see Figures 1 to 3 , Figure 4 and Figure 7 In one embodiment of this utility model, the pressing device 3 is used in a koji-making machine 100, which includes a frame 1 and a koji-making material box 2. The frame 1 has a first position 101 and a second position 102, and the koji-making material box 2 can be conveyed from the first position 101 to the second position 102. The pressing device 3 includes:

[0057] The pressing and flipping mechanism 31 is located at the first position 101 of the frame 1 and is used to press and cover the first side of the yeast material in the yeast material box 2, then flip the yeast material box 2 and output it.

[0058] The pressing and extracting mechanism 32 is located at the second position 102 of the frame 1 and is used to press and extract the second side of the yeast material in the yeast material box 2 to form yeast blocks.

[0059] The position detection mechanism 33 is used to detect the first position 101 and the second position 102, and outputs a first position detection signal when the first position 101 is conveyed with the koji-making material box 2, and outputs a second position detection signal when the second position 102 is conveyed with the koji-making material box 2.

[0060] The control mechanism 34 is electrically connected to the pressing and turning mechanism 31, the pressing and pulping mechanism 32 and the position detection mechanism 33 respectively, and is used to control the pressing and turning mechanism 31 to work according to the first position detection signal, and to control the pressing and pulping mechanism 32 to work according to the second position detection signal.

[0061] It is understandable that the pressing device 3 is used in the koji-making machine 100 to improve the uniformity of material density and the slurry extraction effect during the koji-making process. Specifically, the koji-making machine 100 may include a frame 1, a koji-making material box 2, and the pressing device 3. The frame 1, as the basic structure of the entire koji-making machine 100, is provided with a first position 101 and a second position 102, which are used to place the koji-making material box 2 for different processing steps. This layout helps to realize automated assembly line operation and improve production efficiency. The koji-making material box 2 is a container used to hold the koji material to be processed. It can be conveyed between the first position 101 and the second position 102 of the frame 1 and can effectively cooperate with the koji-pressing and turning mechanism 31 and the koji-pressing and slurry extraction mechanism 32 to achieve bidirectional pressing and slurry extraction of the koji material.

[0062] The conveying of the koji-making material box 2 between the first position 101 and the second position 102 can be achieved by various conveying devices. For example, a transmission belt can be set on the frame 1. The transmission belt can be designed with different widths and lengths as needed and can smoothly convey the koji-making material box 2 from the first position 101 to the second position 102. It has the characteristics of simple structure and convenient maintenance. Alternatively, a roller conveyor can be set on the frame 1. It consists of a series of parallel rollers. When the koji-making material box 2 is placed on it, the material is conveyed by the rotation of the rollers. This conveying method can be easily integrated into the frame 1.

[0063] In this embodiment, the pressing device 3 may include a pressing and flipping mechanism 31, a pressing and slurry extraction mechanism 32, a position detection mechanism 33, and a control mechanism 34. The pressing and flipping mechanism 31 is located at the first position 101 of the frame 1. Its function is to uniformly press the first surface of the yeast material in the yeast material box 2 placed there, and then flip the yeast material box 2 after closing it. This step not only helps to form a uniform density distribution but also prepares for the subsequent slurry extraction process. Through automated control, a more uniform pressure distribution than traditional manual pressing can be achieved, improving production efficiency. The pressing and slurry extraction mechanism 32 is located at the second position 102 of the frame 1. It receives the yeast material box 2 after preliminary processing and performs pressing and slurry extraction operations on the second surface of the yeast material, further ensuring the uniform density of the material and excellent slurry extraction effect, ultimately forming high-quality yeast blocks. The position detection mechanism 33 is responsible for monitoring the status of the first position 101 and the second position 102. When a yeast material box 2 is detected at the corresponding position, a corresponding position detection signal is emitted, such as a first position detection signal or a second position detection signal, providing triggering conditions for subsequent steps. The control mechanism 34 is connected to all the aforementioned mechanisms and intelligently controls the workflow of each mechanism based on signals from the position detection mechanism 33. For example, when it receives the first position detection signal, it will activate the pressing and flipping mechanism 31, and when it receives the second position detection signal, it will activate the pressing and pulping mechanism 32. This method can achieve efficient and precise automated control, greatly improving production efficiency and product quality.

[0064] The technical solution of this utility model addresses the shortcomings of traditional foot-operated pressing methods in terms of density uniformity and pulp extraction effect by setting a pressing device 3 on the koji-making machine 100, while improving production efficiency. First, the pressing and flipping mechanism 31, located at the first position 101 of the frame 1, presses the first side of the koji material placed in the koji-making material box 2, flips the box after it is closed, and outputs the koji material box 2. Subsequently, the koji material box 2 is conveyed to the second position 102 of the frame 1, where the pressing and pulp extraction mechanism 32 presses the second side of the koji material and further completes the pulp extraction process to form the final koji block. Furthermore, the position detection mechanism 33 intelligently detects the status of the first position 101 and the second position 102, issuing a signal when a koji material box 2 is detected at the corresponding position. The control mechanism 34 then precisely controls the workflow of each component based on these signals. This design ensures that the koji material is subjected to uniform pressure in both directions, thereby guaranteeing the consistency of the density inside the koji block and significantly improving the pulp extraction effect. Compared to traditional unidirectional pressing, this method improves the quality of the molded blocks while increasing production efficiency, making large-scale, high-quality molded block production possible. Automated control reduces human intervention, enhancing production stability and reliability.

[0065] Please see Figure 3In one embodiment of this utility model, the koji-making material box 2 includes:

[0066] The box body 21 is provided with a material trough 201 for containing yeast materials, and the box body 21 can be conveyed from the first position 101 to the second position 102.

[0067] The cover plate 22 is detachably disposed at the opening of the material tank 201.

[0068] In this embodiment, the box body 21 is the basic part of the koji-making material box 2, and is designed with one or more material tanks 201 for containing koji materials. The material tanks 201 not only provide storage space, but also ensure the positioning and stability of the koji materials during processing such as pressing, turning, and slurry extraction. The box body 21 is designed to be able to be transported from the first position 101 to the second position 102 of the frame 1 for processing at different workstations. This design allows the material to undergo preliminary pressing and turning at the first position 101, and then be transported to the second position 102 for further pressing and slurry extraction, thereby ensuring that the material can undergo the complete processing flow.

[0069] The cover plate 22 is a detachable part, mainly used in two key steps: First, after the yeast material in the yeast-making box has completed its first pressing, the main function of the cover plate 22 is to cover the material trough 201 of the box body 21. This step is crucial to ensure that the yeast material does not fall or scatter during the entire turning process. By installing the cover plate 22 at the opening of the material trough 201, the yeast material can be effectively protected and its shape and structure can be ensured to be consistent. Second, before the yeast-making material box 2 is conveyed to the second position 102 for the second pressing, the box body 21 needs to be removed to facilitate the processing of the second side of the yeast material. Before the second pressing and extraction, the cover plate 22 is used to receive the turned yeast material, preparing for the next pressing and extraction operation. In other words, the cover plate 22 simplifies the transition steps from the first pressing to the second pressing, allowing the turning and re-pressing of the yeast material to be completed without complicated transfer tools or additional operations, thus improving the overall efficiency of the production line.

[0070] Please see Figure 4 In one embodiment of the present invention, the first position 101 includes a first bending position 1011 and a closing and flipping position 1012 arranged sequentially along the conveying direction of the box body 21.

[0071] The bending and flipping mechanism 31 includes a first bending module 311 and a flipping module 312 sequentially arranged at the first bending position 1011 and the cover flipping position 1012;

[0072] The first pressing module 311 is used to press the four sides of the first surface of the yeast material in the material tank 201 when the box 21 is conveyed to the first pressing position 1011.

[0073] The cover-and-flip module 312 is used to cover the opening of the material trough 201 with the cover plate 22 when the box body 21 is conveyed to the cover-and-flip position 1012, and to flip the koji-making material box 2 and output it.

[0074] In this embodiment, the first position 101 includes two key work stations: the first pressing position 1011 and the lid-closing and flipping position 1012. These two positions are arranged sequentially along the conveying direction of the box 21 to ensure that the yeast material can be processed in the order of the process flow, making the entire yeast-making process smooth and forming an efficient and continuous operation chain from raw material input to finished product output, thereby improving the overall efficiency of the production line.

[0075] The pressing and turning mechanism 31 consists of two parts: a first pressing module 311 located at the first pressing position 1011 and a cover-turning module 312 located at the cover-turning position 1012. The first pressing module 311 presses the four sides of the first surface of the yeast material in the material tank 201 when the box 21 is conveyed to the first pressing position 1011. This design ensures that the yeast material receives uniform pressure in one direction, helping to form a preliminary shape and preparing for subsequent turning and secondary pressing. By precisely controlling the pressure, an ideal density distribution can be achieved without damaging the material. The cover-turning module 312, when the box 21 reaches the cover-turning position 1012, first installs the removable cover 22 onto the opening of the material tank 201 to close it, then turns the entire yeast material box 2 over and outputs it to the pressing and extracting mechanism 32. This step plays a crucial role in protecting the yeast material and preventing it from scattering during the turning process, while also preparing for further processing at the second position 102. Using automation to complete the installation of the cover plate 22 and the flipping of the koji-making material box 2 can not only improve work efficiency, but also reduce the errors that may be caused by manual operation.

[0076] Please see Figure 4 In one embodiment of this utility model, the cover-flipping module 312 includes:

[0077] The cover assembly 3121 is disposed on one side of the first pressing module 311 and is used to transport the cover plate 22 to the top of the box body 21 and cover the opening of the material tank 201.

[0078] The flipping component 3122 is located on the side of the covering component 3121 away from the first pressing module 311, and is used to flip the covered koji-making material box 2 and output it to the pressing and pulping mechanism 32.

[0079] In this embodiment, the lid-closing assembly 3121 is disposed on one side of the first compression module 311. Its main function is to accurately transport the lid 22 to the top of the box body 21 and close it onto the opening of the material trough 201. The lid-closing assembly 3121 can be implemented in many ways. For example, it can include a horizontal motion module and a vertical motion module. The horizontal motion module is responsible for moving the lid 22 from the storage position or the preparatory position to directly above the box body 21. The horizontal motion module can be driven by a transmission mechanism such as a linear guide rail, ball screw, or synchronous belt, with a servo motor or stepper motor providing the power source to ensure positioning accuracy. For example, when the position detection mechanism 33 detects that the box body 21 has reached the lid-closing flip position 1012, the horizontal motion module is activated, driving the gripping device (such as a suction cup or clamp at the end of a robotic arm) mounted on it to move along the X-axis or Y-axis until it is directly above the box body 21. The vertical motion module controls the vertical movement of the cover plate 22 to ensure accurate placement of the cover plate 22 onto the opening of the material trough 201. The vertical motion module is integrated with the horizontal motion module and is implemented using a cylinder, electric actuator, or a similar ball screw-based lifting platform. Continuing the example above, after the horizontal motion module moves the gripping device to the correct position, the vertical motion module lowers the gripping device to the appropriate height and then releases the cover plate 22, allowing it to land accurately on the opening of the material trough 201. The cover assembly 3121 ensures that the yeast starter material will not scatter or become contaminated during subsequent turning.

[0080] The flipping component 3122 is located on the side of the covering component 3121 away from the first pressing module 311, and is responsible for handling the koji-making material box 2 that has completed the covering step. Its key action is to flip the covered koji-making material box 2 and output it to the second position 102 where the pressing and pulping mechanism 32 is located. The flipping component 3122 can be implemented in many ways; for example, it can include a flipping module and a conveying module. The flipping module is responsible for performing the actual flipping action, flipping the covered koji-making material box 2 from a horizontal position to a vertical position or other required angle. The flipping module can use a rotary cylinder, a servo motor with a reducer, and a special clamp. For example, the flipping module can drive a rotating platform with a clamp that can firmly fix the koji-making material box 2 via a servo motor. When the koji-making material box 2 is fed into the working area of ​​the flipping module, the clamp automatically clamps the material box, and then the servo motor drives the rotating platform to rotate according to the preset angle requirements, thereby completing the flipping operation. The conveying module is used to safely and accurately transport the koji-making material box 2 before and after the flipping process, ensuring that it can smoothly enter the flipping module and exit from the flipping module to the next process position. The conveying module may include a chain conveyor, a roller conveyor, or a synchronous belt conveyor system. For example, before the koji-making material box 2 enters the flipping assembly 3122, it is first placed on a chain conveyor, which precisely brings it to the working area of ​​the flipping module. After the flipping is completed, a conveyor belt or robotic arm in another direction takes over and continues to transport the koji-making material box 2 to the second position 102 where the koji pressing and pulping mechanism 32 is located.

[0081] Overall, the effective combination of the closing assembly 3121 and the flipping assembly 3122 makes the entire pressing device 3's workflow smoother, enhances the integration and coordination of the koji-making machine 100, and facilitates the fulfillment of more complex production process requirements. Furthermore, the highly automated flipping assembly 3122 makes the process from closing to flipping to output fast and efficient, significantly shortening the processing time of a single koji-making material box 2 and increasing the overall production line's capacity.

[0082] Please see Figure 5 In one embodiment of the present invention, the first pressing module 311 includes a first pressing head assembly 3111 and a first driving assembly 3112. The first driving assembly 3112 is drivenly connected to the first pressing head assembly 3111 and is used to drive the first pressing head assembly 3111 to press the yeast material in the material tank 201.

[0083] In this embodiment, the first pressing head assembly 3111 is used to directly press the first surface of the yeast material in the material tank 201. The first drive assembly 3112 is driven by the first pressing head assembly 3111, providing power to drive the first pressing head assembly 3111 to complete the pressing operation. The drive assembly can be a hydraulic, pneumatic, or electric system, among which a servo motor is often chosen due to its high-precision control capability. When the box 21 reaches the first pressing position 1011, the first drive assembly 3112 is activated, pushing the first pressing head assembly 3111 downward to press the yeast material in the material tank 201. By precisely controlling the force and stroke of the first drive assembly 3112, it can be ensured that the yeast material obtains the ideal density without being damaged.

[0084] Please see Figure 6 In one embodiment of the present invention, the first pressure head assembly 3111 includes:

[0085] First pressure head slide 31111;

[0086] Multiple first fixed shafts 31112 are spaced apart on the edge of the first pressure head slide 31111. Each first fixed shaft 31112 is fitted with a first elastic element 31113. A first locking element 31114 is provided at the end of each first fixed shaft 31112 away from the first pressure head slide 31111.

[0087] The first fixture connecting plate 31115 is sleeved on a plurality of first fixed shafts 31112 and is located between the first pressure head slide 31111 and a plurality of first locking members 31114. The first fixture connecting plate 31115 is drivenly connected to the first drive assembly 3112.

[0088] The first flattening tool 31116 is disposed on the side of the first tool connecting plate 31115 near the first pressure head slide 31111 and facing the first bending position 1011. The first pressure head slide 31111 is provided with a first bending opening 301 for the first flattening tool 31116 to pass through.

[0089] In this embodiment, the first pressure head slide 31111 serves as the main support structure of the entire first pressure head assembly 3111. It does not directly participate in the pressing process of the yeast material, but provides a basis for the installation and movement of other components.

[0090] Multiple first fixed shafts 31112 are spaced apart on the edge of the first pressure head slide 31111. Each first fixed shaft 31112 is fitted with a first elastic element 31113 (e.g., a spring), and a first locking element 31114 (e.g., a nut) is provided at the end away from the first pressure head slide 31111. The first fixed shafts 31112 provide structural support, while the first elastic elements 31113 enable flexible adjustment, allowing the first flattening jig 31116 to be finely adjusted according to the different shapes and hardness of the material to achieve the best pressing effect.

[0091] The first fixture connecting plate 31115 is sleeved on multiple first fixed shafts 31112 and located between the first pressure head slide 31111 and multiple first locking elements 31114. It is directly connected to the first drive assembly 3112 and is responsible for receiving and transmitting power to the first flattening fixture 31116. Since the first fixture connecting plate 31115 can move freely on the first fixed shafts 31112 and is influenced by the first elastic element 31113, this helps to ensure uniform pressure distribution throughout the pressing process.

[0092] The first flattening tool 31116 is located on the side of the first tool connecting plate 31115 near the first pressure head slide 31111 and facing the first pressing position 1011. It is the part that actually performs the pressing work on the yeast material. The first pressure head slide 31111 is provided with a first pressing port 301 for the first flattening tool 31116 to pass through, so that the first flattening tool 31116 can accurately act on the yeast material in the material tank 201 and ensure that the material is uniformly compacted.

[0093] The working principle of the first pressure head assembly 3111 involves the coordinated action of multiple components, from receiving power to precisely pressing the yeast material. The following is a detailed description of the entire workflow of the first pressure head assembly 3111:

[0094] The entire movement of the first pressing head assembly 3111 begins with the first drive assembly 3112 providing power, driving the first jig connecting plate 31115 forward along multiple first fixed shafts 31112. The first jig connecting plate 31115 drives the first flattening jig 31116 connected to it to move towards the first pressing head slide 31111, and performs a pressing operation by aligning the first pressing port 301 on the first pressing head slide 31111 with the yeast material in the material tank 201. During this process, the first elastic element 31113 sleeved on each first fixed shaft 31112 can flexibly adjust the pressure distribution according to the actual resistance of the material, ensuring that the pressure applied to the yeast material is uniform and appropriate. After pressing is completed, the first drive assembly 3112 drives the first jig connecting plate 31115 in the reverse direction, causing it to retract along the first fixed shaft 31112 to the initial position, ready for the next working cycle. During this process, the first pressure head slide 31111 acts as the supporting body to maintain the stability and positioning accuracy of the entire component, while the first elastic element 31113 ensures flexibility and adaptability during the pressing process. In this way, through a series of precisely designed mechanical actions, efficient and uniform pressing of the yeast material is achieved.

[0095] Please see Figure 6 In one embodiment of this utility model, the first flattening fixture 31116 includes:

[0096] A pressure plate 31116a is disposed toward the first bending position 1011, and the cross-sectional shape of the pressure plate 31116a is adapted to the groove shape of the material trough 201.

[0097] The first fixing block 31116b and the second fixing block 31116c are spaced apart and opposite to each other on the first fixture connecting plate 31115, and the first fixing block 31116b and the second fixing block 31116c connect the pressure plate 31116a.

[0098] In this embodiment, the pressure plate 31116a is the part that directly contacts the yeast material and is positioned facing the first pressing position 1011. To ensure that the pressure applied to the material is uniform and effective, the cross-sectional shape of the pressure plate 31116a is designed to fit the opening shape of the material tank 201. This design ensures that during the pressing process, the pressure plate 31116a can apply uniformly distributed pressure to the material and can completely cover the opening of the material tank 201, preventing the material from overflowing from the edges or being subjected to uneven pressure, thereby improving the quality and consistency of the final product.

[0099] The first fixing block 31116b and the second fixing block 31116c are spaced apart and opposite to each other on the first jig connecting plate 31115. These two fixing blocks not only enhance the structural strength of the entire first flattening jig 31116, but also firmly connect the pressure plate 31116a to the first jig connecting plate 31115, so that the pressure plate 31116a can remain stable under high pressure and is not prone to displacement or deformation, thereby ensuring long-term reliability. Through this design, it is ensured that the pressure plate 31116a remains stable during the pressing operation and can effectively transmit the power from the first drive assembly 3112.

[0100] Please see Figures 3 to 6 In one embodiment of this utility model, multiple material troughs 201 are provided, and the multiple material troughs 201 are spaced apart along the length direction of the box body 21; multiple first pressing head assemblies 3111 and multiple first driving assemblies 3112 are respectively provided, and the multiple first pressing head assemblies 3111 and the multiple first driving assemblies 3112 are electrically connected one-to-one. When the box body 21 is conveyed to the first pressing position 1011, the positions of the multiple first pressing head assemblies 3111 correspond one-to-one with the positions of the multiple material troughs 201.

[0101] In this embodiment, the box body 21 is provided with multiple material slots 201, which are spaced apart along the length of the box body 21. This design allows for the processing of more yeast material at once, thereby improving production efficiency. To correspond to each material slot 201, multiple first pressing head assemblies 3111 are also provided, and their number matches the number of material slots 201. When the box body 21 is conveyed to the first pressing position 1011, the positions of the multiple first pressing head assemblies 3111 correspond one-to-one with the positions of the multiple material slots 201, ensuring that the yeast material in each material slot 201 can be accurately pressed. Each first pressing head assembly 3111 is equipped with an independent first drive assembly 3112, and the two are electrically connected one-to-one. This allows for independent control of each first pressing head assembly 3111, ensuring that the yeast material in each material slot 201 can obtain the appropriate pressing force as needed.

[0102] Please see Figure 7 In one embodiment of the present invention, the second position 102 includes a pick-up and put-out position 1021, a second pressing position 1022 and a pulp lifting position 1023 arranged sequentially along the conveying direction of the box body 21.

[0103] The pressing and lifting mechanism 32 includes a picking and placing module 321, a second pressing module 322, and a lifting module 323, which are sequentially arranged at the picking and placing position 1021, the second pressing position 1022, and the lifting position 1023.

[0104] The pick-and-place module 321 is used to remove the box 21 when the koji material box 2 is conveyed to the pick-and-place position 1021, so as to expose the koji material on the cover plate 22.

[0105] The second pressing module 322 is used to press the four sides of the second side of the yeast material on the cover plate 22 when the cover plate 22 is conveyed to the second pressing position 1022;

[0106] The extraction module 323 is used to extract moisture from the yeast material on the cover plate 22 when the cover plate 22 is conveyed to the extraction position 1023 to form yeast blocks before output.

[0107] In this embodiment, the second position 102 includes three key work stations arranged sequentially along the conveying direction of the box body 21: the pick-and-place position 1021, the first pressing position 1011, and the pulp extraction position 1023. These three positions ensure that the yeast material can be processed in the order of the process flow, making the entire yeast-making process smoother and forming an efficient and continuous operation chain from raw material input to finished product output, thereby improving the overall efficiency of the production line.

[0108] The pressing and extraction mechanism 32 consists of three parts: a picking and placing module 321 located at the picking and placing position 1021, a second pressing module 322 located at the second pressing position 1022, and an extraction module 323 located at the extraction position 1023. The picking and placing module 321 removes the koji material box 21 when it is conveyed to the picking and placing position 1021, that is, the box 21 separates from the cover plate 22, thus exposing the koji material on the cover plate 22. This step prepares for subsequent processing of the second side of the koji material. Precise control ensures that it will not be damaged or deformed during this process. The second pressing module 322 is responsible for pressing the four sides of the second side of the koji material on the cover plate 22 when the cover plate 22 (along with the koji material on it) is conveyed to the second pressing position 1022. This step is crucial for forming koji blocks of uniform density and ensuring that the final product has good structural strength and fermentation performance. Precise pressure control allows for an ideal density distribution without damaging the material. The extraction module 323 is used to extract moisture from the yeast material when the cover plate 22 (along with the yeast material on it) is conveyed to the extraction position 1023, forming yeast blocks and outputting the finished product. This process not only helps to adjust the humidity of the yeast material to achieve optimal fermentation, but also promotes the activity of microorganisms and enzymes, improving the quality of the final product. By pressing the yeast material on both sides separately and performing extraction in the final stage, the consistency of key parameters such as density and humidity of each batch of product can be improved. Automating the unloading, secondary pressing, and extraction processes not only improves work efficiency but also reduces errors that may be caused by manual operation, thereby improving overall production efficiency.

[0109] Please see Figure 8 In one embodiment of this utility model, the extraction module 323 may include a first extraction module 3231 and a second extraction module 3232. Correspondingly, the extraction position 1023 may include a first extraction position 10231 and a second extraction position 10232 arranged sequentially. The first extraction module 3231 is positioned towards the first extraction position 10231. After the secondary pressing is completed, the cover plate 22 is placed on this surface, and the first extraction module 3231 performs the initial extraction operation on the pressed yeast material to promote the activity of microorganisms and enzymes required for fermentation. The second extraction module 3232 is positioned towards the second extraction position 10232, and the cover plate 22 and yeast material after the initial extraction can be placed on this surface for a second extraction process. Through staged extraction processing, the effective components in the yeast material can be extracted more effectively, improving the quality and efficiency of the fermentation process.

[0110] Please see Figure 8In one embodiment of the present invention, the second pressing module 322 includes a second pressing head assembly 3221 and a second driving assembly 3222. The second driving assembly 3222 is drivenly connected to the second pressing head assembly 3221 and is used to drive the second pressing head assembly 3221 to press the yeast material on the cover plate 22.

[0111] In this embodiment, the second pressing head assembly 3221 is used to press the second side of the yeast material on the cover plate 22. The second drive assembly 3222 is driven by the second pressing head assembly 3221, providing the necessary power to drive the second pressing head assembly 3221 to complete the pressing operation. Similar to the first drive assembly 3112, different drive methods such as hydraulic, pneumatic, or electric (e.g., servo motor) can be selected. When the cover plate 22 (along with the yeast material on it) reaches the second pressing position 1022, the second drive assembly 3222 is activated, driving the second pressing head assembly 3221 to press the second side of the yeast material. This process ensures that both sides of the yeast material are fully pressed, which helps to form high-quality yeast blocks.

[0112] Please see Figure 9 In one embodiment of the present invention, the second pressure head assembly 3221 includes:

[0113] Second pressure head slide 32211;

[0114] Multiple second fixed shafts 32212 are spaced apart on the edge of the second pressure head slide 32211. Each second fixed shaft 32212 is fitted with a second elastic element 32213. A second locking element 32214 is provided at the end of each second fixed shaft 32212 away from the second pressure head slide 32211.

[0115] The second fixture connecting plate 32215 is sleeved on a plurality of second fixed shafts 32212 and located between the second pressure head slide 32211 and a plurality of second locking members 32214. The second fixture connecting plate 32215 is drivenly connected to the second drive assembly 3222.

[0116] The second flattening tool 32216 is disposed on the side of the second tool connecting plate 32215 near the second pressure head slide 32211 and facing the second pressing position 1022. The second pressure head slide 32211 is provided with a second pressing opening 302 for the first flattening tool 31116 to pass through.

[0117] In this embodiment, the second pressure head slide 32211 serves as the main support structure of the entire second pressure head assembly 3221. It does not directly participate in the pressing process of the yeast material, but provides a basis for the installation and movement of other components.

[0118] Multiple second fixed shafts 32212 are spaced apart on the edge of the second pressure head slide 32211. Each second fixed shaft 32212 is fitted with a second elastic element 32213 (e.g., a spring), and a second locking element 32214 (e.g., a nut) is provided at the end away from the second pressure head slide 32211. The second fixed shafts 32212 provide structural support, while the second elastic elements 32213 enable flexible adjustment, allowing the second flattening jig 32216 to be finely adjusted according to the different shapes and hardness of the material to achieve the best pressing effect.

[0119] The second fixture connecting plate 32215 is sleeved on multiple second fixed shafts 32212 and located between the second pressure head slide 32211 and multiple second locking elements 32214. It is directly connected to the second drive assembly 3222 and is responsible for receiving and transmitting power to the second flattening fixture 32216. Since the second fixture connecting plate 32215 can move freely on the second fixed shafts 32212 and is influenced by the second elastic element 32213, this helps to ensure uniform pressure distribution throughout the pressing process.

[0120] The second flattening tool 32216 is located on the side of the second tool connecting plate 32215 near the second pressure head slide 32211 and facing the second pressing position 1022. It is the part that actually performs the pressing work on the yeast material. The second pressure head slide 32211 is provided with a second pressing port 302 for the second flattening tool 32216 to pass through, so that the second flattening tool 32216 can accurately act on the yeast material in the material tank 201 and ensure that the material is uniformly compacted.

[0121] The working principle of the second pressure head assembly 3221 involves the coordinated action of multiple components, from receiving power to precisely pressing the yeast material. The following is a detailed description of the entire workflow of the second pressure head assembly 3221:

[0122] The entire movement of the second pressing head assembly 3221 begins with the second drive assembly 3222 providing power, driving the second jig connecting plate 32215 forward along multiple second fixed shafts 32212. The second jig connecting plate 32215 drives the connected second flattening jig 32216 towards the second pressing head slide 32211, aligning the second pressing port 302 on the second pressing head slide 32211 with the yeast material in the material tank 201 for pressing. During this process, the second elastic element 32213, sleeved on each second fixed shaft 32212, can flexibly adjust the pressure distribution according to the actual resistance of the material, ensuring that the pressure applied to the yeast material is uniform and appropriate. After pressing is completed, the second drive assembly 3222 reverses the direction of the second jig connecting plate 32215, causing it to retract along the second fixed shaft 32212 to its initial position, ready for the next work cycle. During this process, the second pressure head slide 32211 acts as a support to maintain the stability and positioning accuracy of the entire assembly, while the second elastic element 32213 ensures flexibility and adaptability during the pressing process. In this way, through a series of precisely designed mechanical actions, efficient and uniform pressing of the yeast material is achieved.

[0123] Please see Figure 10 In one embodiment of the present invention, the second flattening tool 32216 is provided with a pressing groove 303. The end of the pressing groove 303 facing the second bending position 1022 is an open end, and the end of the pressing groove 303 away from the second bending position 1022 is a closed end. The pressing groove 303 is gradually widened from the closed end to the open end.

[0124] In this embodiment, since the pressing groove 303 is gradually widened from the closed end to the open end, that is, the pressing groove 303 is turtle-back shaped, it can more effectively adapt to the natural shape of the material during the secondary pressing process, so that the pressure can be more evenly distributed on the surface of the material, thereby improving the quality of the final product.

[0125] Please see Figure 3 and Figure 8 In one embodiment of this utility model, multiple material troughs 201 are provided, and the multiple material troughs 201 are spaced apart along the length direction of the box body 21; multiple second pressing head assemblies 3221 and multiple second driving assemblies 3222 are respectively provided, and the multiple second pressing head assemblies 3221 are electrically connected to the multiple second driving assemblies 3222 one-to-one. When the box body 21 is conveyed to the second pressing position 1022, the positions of the multiple second pressing head assemblies 3221 correspond one-to-one with the positions of the multiple material troughs 201.

[0126] In this embodiment, the box body 21 is provided with multiple material slots 201, which are spaced apart along the length of the box body 21. This design allows for the processing of more yeast material at once, thereby improving production efficiency. Similar to the first pressing head assembly 3111, multiple second pressing head assemblies 3221 are also provided, and their number matches the number of material slots 201. When the cover plate 22 (along with the yeast material on it) is conveyed to the second pressing position 1022, the positions of the multiple second pressing head assemblies 3221 correspond one-to-one with the positions of the multiple material slots 201, ensuring that the second side of the yeast material in each material slot 201 can be accurately pressed. Each second pressing head assembly 3221 has a corresponding second drive assembly 3222, and the two are also electrically connected one-to-one. This design allows each second pressing head assembly 3221 to operate independently according to specific needs, ensuring that the yeast material in each material slot 201 is properly processed during the secondary pressing process.

[0127] Please see Figure 1 In one embodiment of this utility model, the pressing device 3 further includes:

[0128] The pressure detection mechanism 35 is electrically connected to the control mechanism 34. The pressure detection mechanism 35 is used to detect the pressure applied to the yeast material by the yeast pressing and turning mechanism 31 and / or the yeast pressing and pulping mechanism 32. The control mechanism 34 is used to control the yeast pressing and turning mechanism 31 and / or the yeast pressing and pulping mechanism 32 to adjust the pressure output to the yeast material according to the pressure detected by the pressure detection mechanism 35.

[0129] In this embodiment, the pressure detection mechanism 35 is electrically connected to the control mechanism 34, and is mainly used to monitor in real time the actual pressure applied to the yeast material by the pressing and turning mechanism 31 and / or the pressing and extracting mechanism 32. Pressure sensors can be installed at key parts of the pressing and turning mechanism 31 and / or the pressing and extracting mechanism 32 to ensure accurate capture of the pressure applied to the yeast material. The control mechanism 34 receives pressure data from the pressure detection mechanism 35 and dynamically adjusts the output pressure of the pressing and turning mechanism 31 and / or the pressing and extracting mechanism 32 based on this data. This feedback control system ensures that each pressing step is carried out under optimal pressure conditions, avoiding product quality problems caused by insufficient or excessive pressure. The real-time pressure monitoring and automatic adjustment mechanism helps prevent product defects caused by improper pressure, such as uneven density and loose structure, thereby improving the quality of the final fermented product.

[0130] This utility model also proposes a koji-making machine 100, please refer to [link / reference]. Figure 1 and Figure 2The koji-making machine 100 includes a frame 1, a koji-making material box 2, and a pressing device 3. The specific structure of the pressing device 3 is as described in the above embodiments. Since the koji-making machine 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0131] The frame 1 is the basic structure of the entire equipment, and it is equipped with a first position 101 and a second position 102. These two positions are used to support the conveying process of the koji-making material box 2 within it, ensuring that each processing step can be performed in the correct position.

[0132] The koji-making material box 2 is a container specifically designed to hold the koji material to be processed. It can move from a first position 101 to a second position 102 on the frame 1 to receive appropriate processing at different stages. As previously described, the koji-making material box 2 includes a box body 21 with a material trough 201 and a removable cover 22. The material trough 201 is used to hold the koji material, while the cover 22 is used to protect the material and assist in the tilting operation when necessary.

[0133] The pressing device 3 is the core component of the entire koji-making machine 100. It completes the pressing and shaping of the koji material through the coordinated operation of the koji-pressing and turning mechanism 31, the koji-pressing and pulp-extracting mechanism 32, the position detection mechanism 33, and the control mechanism 34. The following is a detailed description of its overall working process:

[0134] In the initial state, the box 21 is loaded with the yeast material to be processed and is located at the first pressing position 1011 of the frame 1, and the cover plate 22 has not yet been installed on the material tank 201.

[0135] In the first stage, the position detection mechanism 33 detects that the koji-making material box 2 has reached the first position 101 and sends a first position detection signal to the control mechanism 34. After receiving the signal, the control mechanism 34 starts the first pressing module 311. The first drive assembly 3112 drives the first pressing head assembly 3111 to perform preliminary four-sided pressing of the koji material in the material tank 201 to ensure that the material has a preliminary shape and density. After the preliminary pressing is completed, the capping assembly 3121 moves the cover plate 22 above the box body 21 and accurately covers the opening of the material tank 201. The flipping assembly 3122 then flips the entire koji-making material box 2 so that the cover plate 22 faces down and outputs it to the next process preparation area.

[0136] In the second stage, the position detection mechanism 33 detects that the koji-making material box 2 has been successfully flipped and is ready to be conveyed to the second position 102. The control mechanism 34 coordinates the conveying module to convey the koji-making material box 2 from the first position 101 to different workstations in the second position 102: pick-up and place position 1021, second koji-pressing position 1022, and slurry-lifting position 1023. The pick-up and place module 321 first operates at the pick-up and place position 1021, removing the box 21 from the material tank 201 to expose the koji material on the cover plate 22. The position detection mechanism 33 confirms that the koji-making material box 2 has reached the second koji-pressing position 1022 and notifies the control mechanism 34. The control mechanism 34 activates the second koji-pressing module 322. The second drive assembly 3222 drives the second press head assembly 3221 to perform a second four-sided pressing of the koji material on the cover plate 22, further ensuring the uniformity of the material and the structural strength. After the secondary pressing is completed, the control mechanism 34 directs the conveying module to move the koji material box 2 to the extraction position 1023. At the extraction position 1023, the extraction module 323 begins operation, extracting excess moisture from the koji material to form the final koji block. During the extraction process, mechanical pressure or vacuum technology may be used to remove excess moisture, ensuring that the koji block reaches the ideal moisture level. After the position detection mechanism 33 confirms that the extraction operation is complete, the control mechanism 34 can direct the conveying system to output the finished koji block. After the entire process is completed, the koji material box 2 can be reloaded with new koji material, ready for a new pressing cycle.

[0137] Please see Figure 1 and Figure 2In one embodiment of this utility model, the koji-making machine 100 may also include a feeding device 4, a discharging device 5, and a flipping and pressing device 6. The feeding device 4 is responsible for supplying koji material to the koji-making material box 2 and automatically conveying the koji-making material box 2 containing the koji material to the pressing and flipping mechanism 31. It consists of a feeding module and a conveying module. The feeding module can accurately measure and distribute the koji material into each koji-making material box 2, ensuring the consistency of each batch of material. The conveying module utilizes a conveyor belt, robotic arm, or other automated handling equipment to ensure that the koji-making material box 2 can smoothly move from the feeding position to the first position 101, achieving an efficient and error-free operation process. After all processing steps are completed, the discharging device 5 is used to separate the cover plate 22 of the koji-making material box 2 from the final formed koji block. This device is designed with a special mechanism to remove the cover plate 22 and output it, and also has tools for safely removing and transferring the formed koji block, avoiding any possible damage. The flipping and pressing device 6 is specifically designed to handle the box 21 before secondary pressing and the cover plate 22 after secondary slurry extraction. It first precisely integrates and flips the two, then presses them together, and finally sends the integrated koji-making material box 2 back to the pressing and flipping mechanism 31, ready for the next stage of processing or direct output. This device ensures accurate alignment and flipping of the box 21 before secondary pressing and the cover plate 22 after secondary slurry extraction, greatly improving the precision and stability of the entire production process. By integrating the feeding device 4, the discharging device 5, and the flipping and pressing device 6, the koji-making machine 100 can achieve fully automated operation from raw material input to finished product output, greatly reducing the need for manual intervention and significantly improving production efficiency. This design not only optimizes the process flow but also ensures product consistency and high quality, meeting the demands of the modern brewing industry for efficient and intelligent production equipment.
