DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figures 1 to 9 As shown, the automated fermentation equipment for food processing of the present invention comprises a tank body 1, a feed inlet 12 is installed on the top of the tank body 1, a discharge port 13 is installed on the bottom of the tank body 1, a water spray ring 7 is installed on the top of the tank body 1, and the water spray ring 7 is connected to an external water pump through a water inlet pipe 15; The tank body 1 is provided with a motor 11, a rotating shaft 2 is provided inside the tank body 1, the motor 11 drives the rotating shaft 2 to rotate, a connecting rod 3 is provided on the rotating shaft 2, a mounting plate 4 is provided on the connecting rod 3, a cleaning plate 5 is provided on the mounting plate 4, and the cleaning plate 5 is in contact with the inner wall of the tank body 1; A discharge plate 6 is installed at the lower end of the rotating shaft 2; The cleaning plates 5 are evenly arranged in a plurality of groups along the length direction of the mounting plate 4, and the cleaning plates 5 are in contact with each other; The cleaning plates 5 are elastic and symmetrically arranged on the mounting plate 4. An elastic membrane 51 is installed between the cleaning plates 5. The elastic membrane 51 seals the space between the cleaning plates 5 to form a deformation cavity. The surfaces of the cleaning plates 5, the mounting plate 4, the connecting rod 3 and the rotating shaft 2 have a hydrophobic layer. During operation, materials and microorganisms are put into the tank body 1 from the feed port 12, and then the motor 11 is controlled by the controller to rotate, so that the rotating shaft 2, the connecting rod 3, the mounting plate 4, the cleaning plate 5 and the discharge plate 6 start to rotate synchronously, so as to stir the materials and microorganisms entering the tank body 1, promote the full mixing of the materials, thereby improving the final fermentation quality, and then, after the fermentation is completed, the materials in the tank body 1 are discharged from the discharge port 13; During the material discharge process, the discharge plate 6 on the rotating shaft 2 will stir and scrape the bottom surface of the tank body 1, so that the material at the bottom of the tank body 1 is pushed, thereby promoting and accelerating the discharge of the material from the discharge port 13, avoiding the accumulation of materials at the bottom of the tank body 1 and affecting the discharge of the material. At the same time, the cleaning plate 5 rotating synchronously with the rotating shaft 2 will scrape and clean the inner wall of the tank body 1, so that the material attached to the inner wall of the tank body 1 is quickly detached and dropped, avoiding or reducing the residue of the material in the tank body 1, and avoiding affecting the subsequent use of the fermentation equipment; at the same time, after the material in the tank body 1 is discharged and the tank body 1 is cleaned, the controller will control the external water pump to pump clean water The water is fed into the water spray ring 7 through the water inlet pipe 15, and then sprayed onto the inner wall of the tank body 1. At this time, the rotating shaft 2 will drive the cleaning plate 5 to rotate along the inner wall of the tank body 1, so as to clean the materials attached to the inner wall of the tank body 1. At the same time, the clean water sprayed from the water spray ring 7 will temporarily gather at the bottom of the tank body 1, and the rotating discharge plate 6 will stir the clean water at the bottom of the tank body 1, so as to clean the inner wall near the bottom of the tank body 1, and avoid the residual materials from adhering to the inner wall of the bottom of the tank body 1, that is, the inner wall below the cleaning plate 5, so that under the cooperation of the cleaning plate 5 and the discharge plate 6, it is ensured that the residual materials on the inner wall of the tank body 1 are cleaned well. At the same time, due to the elasticity of the cleaning plate 5 and the hydrophobic layer provided on each component, during the cleaning process, after the cleaning plate 5 scrapes off the residual material on the inner wall of the tank body 1, the residual material is easy to slide and fall off from the surface of the cleaning plate 5, making it easy for the material to fall to the bottom of the tank body 1, and then the residual material is collected and discharged, reducing the possibility of residual material on the inner wall of the tank body 1 and the cleaning plate 5; At the same time, since there are multiple groups of cleaning plates 5, when there are relatively many residual materials, the materials will squeeze the cleaning plates 5, causing the cleaning plates 5 to deform and forming gaps between the cleaning plates 5, further promoting the cleaned materials to pass through the gaps between the cleaning plates 5 and fall to the bottom of the tank body 1, thereby preventing the materials from continuously adhering to the cleaning plates 5, resulting in residual materials still adhering to the cleaning plates 5 after the residual materials on the inner wall of the tank body 1 are cleaned, affecting the cleaning effect of the fermentation equipment and the subsequent normal use of the fermentation equipment; At the same time, since a deformation cavity is formed between the cleaning plates 5 through the elastic membrane 51, during the process of cleaning the residual materials on the inner wall of the tank body 1, the deformation cavity is easily blocked by the residual materials and deformed, and then the materials attached to the surface of the cleaning plates 5 are squeezed, vibrated or impacted, thereby promoting the cleaned residual materials to fall off the cleaning plates 5, avoiding the presence of cleaned residual materials on the cleaning plates 5, affecting the cleaning effect of the fermentation equipment and the subsequent fermentation quality of the fermentation equipment.

[0019] As an embodiment of the present invention, an elastic block 43 is installed in the deformation cavity, a guide rod 41 is provided on the mounting plate 4, a slider 42 is slidably installed on the guide rod 41, and the slider 42 is located between the elastic block 43 and the mounting plate 4; The slider 42 and the cleaning plate 5 are in contact with each other, and the surfaces of the slider 42 and the cleaning plate 5 are smooth. The motor 11 periodically adjusts the rotation speed under the control of the controller; When the cleaning plate 5 cleans the inner wall of the tank body 1, the slider 42 will move away from the mounting plate 4 under the action of centrifugal force, and then cooperate with the elastic block 43 and the periodic change of the motor 11 speed to make the slider 42 reciprocate in the deformation chamber. At this time, due to the contact between the slider 42 and the cleaning plate 5, the size of the space of the deformation chamber on both sides of the slider 42 will change when the slider 42 reciprocates, thereby causing pressure changes, so that the cleaning plate 5 and the elastic membrane 51 will deform and vibrate under the action of pressure, thereby further cleaning the material on the surface of the cleaning plate 5, promoting and accelerating the detachment of the material on the surface of the cleaning plate 5, avoiding the residual material on the cleaning plate 5, affecting the cleaning effect of the fermentation equipment and the subsequent fermentation quality of the fermentation equipment.

[0020] As an embodiment of the present invention, the slider 42 is magnetic, and a magnetic block 44 is installed on the inner wall of the tank body 1. There is a magnetic attraction between the magnetic block 44 and the slider 42. The water spray ring 7 is provided with a cross bar 71, and the magnetic block 44 and the cross bar 71 are located on the same vertical plane; By setting the cross bar 71, the connecting rod 3, the mounting plate 4 and the cleaning plate 5 are sprayed with water to further avoid the presence of materials on the connecting rod 3, the mounting plate 4 and the cleaning plate 5, thereby ensuring the cleaning effect of the fermentation equipment; At the same time, when the cleaning plate 5 rotates to the position of the magnetic block 44, the slider 42 will be affected by the magnetic attraction of the magnetic block 44, so that the slider 42 quickly rushes in the direction of the magnetic block 44. In this case, the movement speed of the slider 42 is relatively fast, and the pressure change caused by the slider 42 in the deformation chamber is relatively drastic, so that the vibration and deformation of the cleaning plate 5 and the elastic membrane 51 are also relatively drastic, so that through relatively drastic vibration and deformation, the residual material on the cleaning plate 5 is promoted and accelerated to detach and fall to the bottom of the tank body 1, and then discharged to the outside of the tank body 1, thereby ensuring a good cleaning effect of the fermentation equipment.

[0021] As an embodiment of the present invention, the cleaning plate 5 is arranged obliquely on the mounting plate 4; Since the cleaning plate 5 is arranged at an angle, when the cleaning plate 5 cleans the inner wall of the tank body 1, the residual materials scraped and cleaned from the inner wall of the tank body 1 by the cleaning plate 5 will slide down along the downward slope of the cleaning plate 5, further promoting and accelerating the detachment and falling of the residual materials on the cleaning plate 5.

[0022] As an embodiment of the present invention, the connecting rod 3 includes a fixed rod 31 and a movable rod 32, the fixed rod 31 has an installation cavity, the movable rod 32 is slidably installed in the installation cavity, and a spring 33 is installed between the movable rod 32 and the bottom surface of the installation cavity; A connecting cavity 22 is provided in the rotating shaft 2, and the installation cavity and the connecting cavity 22 are connected to each other. A gas path rotary connector 21 is installed on the upper end of the rotating shaft 2, and an air inlet pipe 14 is installed on the air path rotary connector 21. The air inlet pipe 14 is connected to an external air source, and the connecting cavity 22 is connected to the gas path rotary connector 21. When cleaning the fermentation equipment, the air sent in by the external air source will enter the installation cavity after passing through the air inlet pipe 14, the air path rotary connector 21, and the connecting cavity 22, and then push the movable rod 32 in the installation cavity to extend, so that the cleaning plate 5 is closely attached to the inner wall of the tank body 1, and the inner wall of the tank body 1 is cleaned; At the same time, during the fermentation process, the external air source does not introduce air or introduces air with lower pressure, which reduces the pressure in the installation cavity, causing the movable rod 32 to be retracted into the installation cavity under the action of the spring 33. At this time, the installation plate 4 and the cleaning plate 5 will act as stirring blades, and cooperate with the discharge plate 6 to stir the material inside the tank body 1, promoting full mixing of the material, thereby improving the fermentation effect and fermentation quality of the fermentation equipment.

[0023] As an embodiment of the present invention, a plurality of connecting cavities 22 are provided in the rotating shaft 2, and the connecting cavities 22 are connected to a plurality of independent air inlet pipes 14 through air path rotary connectors 21. A plurality of connecting rods 3 are installed on the rotating shaft 2, and each group of the connecting rods 3 corresponds to the connecting cavities 22 one by one. The connecting rods 3 are divided into different groups according to the maximum lengths of the movable rods 32; At the same time, when cleaning the fermentation equipment, the controller will control the external air source to periodically introduce air, so that the pressure in the installation cavity changes periodically, thereby causing the movable rod 32 to reciprocate. In this case, with the rapid extension and retraction of the movable rod 32, the residual materials attached to the installation plate 4 and the cleaning plate 5 are subjected to a greater impact, further promoting the residual materials to separate from the surfaces of the installation plate 4 and the cleaning plate 5, avoiding the residual materials on the cleaning plate 5, affecting the cleaning effect of the fermentation equipment and affecting the subsequent fermentation quality of the fermentation equipment; At the same time, since there are multiple groups of connecting rods 3, and the maximum extension lengths of the movable rods 32 of different groups are different, and when the pressure of the incoming air is different, the extension lengths of the movable rods 32 are also different. Therefore, during the fermentation process, the external air source is controlled by the controller to change the pressure of the incoming air, so that the distances between the movable rods 32, the mounting plates 4 and the cleaning plates 5 of different groups relative to the rotating shaft 2 are different, thereby stirring the materials in different areas of the tank body 1, promoting the mixing effect of the materials in the tank body 1, and improving the fermentation effect of the fermentation equipment.

[0024] As an embodiment of the present invention, the discharge plate 6 is provided with a bubble hole, and the bubble hole is connected to the connecting cavity 22 in the rotating shaft 2; A pressure valve 34 is installed between the connecting cavity 22 and the installation cavity, and between the connecting cavity 22 and the bubble hole. The operating pressure of the pressure valve 34 between the connecting cavity 22 and the installation cavity is lower than the operating pressure of the pressure valve 34 between the connecting cavity 22 and the bubble hole. During the fermentation process, when the pressure of the incoming air is less than the operating pressure of the pressure valve 34 between the connecting chamber 22 and the bubble hole, the movable rod 32 can be extended or retracted to complete the stirring of the material. At the same time, when the pressure of the incoming air is greater than the operating pressure of the pressure valve 34 between the connecting chamber 22 and the bubble hole, the movable rod 32 is fully extended, the cleaning plate 5 contacts the inner wall of the tank body 1, and the air is discharged from the bubble hole, thereby supplying sufficient oxygen to the fermentation process, facilitating the rapid reproduction of microorganisms and improving the fermentation quality. At the same time, during the cleaning process, the air ejected from the bubble hole will stir the clean water at the bottom of the tank body 1 and generate a large number of bubbles, thereby using the bubbles to impact the discharge plate 6, or when a large amount of clean water is filled in the tank body 1, the connecting rod 3, the mounting plate 4, and the cleaning plate 5 are impacted, thereby further improving the cleaning effect of the fermentation equipment and ensuring that the fermentation quality of the fermentation equipment is good during subsequent use.

[0025] A fermentation method for an automated fermentation device for food processing, the fermentation method being applicable to any of the automated fermentation devices for food processing described above, the fermentation method comprising the following steps: S1: Start the motor 11 and add the material and microorganisms into the tank body 1 from the feed port 12, and stir the material in the tank body 1 through the connecting rod 3 and the discharge plate 6; S2: The controller opens the external air source according to the set ventilation program, and introduces the purified air into the tank body 1 through the air inlet pipe 14; the pressure of the introduced air is greater than the operating pressure of the pressure valve 34 between the connecting cavity 22 and the bubble hole; S3: After the controller completes the ventilation program, it controls the external air source to reduce the ventilation pressure, so that the pressure of the air entering is less than the operating pressure of the pressure valve 34 between the connecting cavity 22 and the bubble hole. After that, the controller continues to control the motor 11 to operate slowly according to the set fermentation program, waiting for the fermentation of the material in the tank body 1 to be completed; after the fermentation of the material is completed, it is discharged from the discharge port 13; S4: The controller controls the external water pump to deliver clean water from the water inlet pipe 15 into the tank body 1 according to the set cleaning program, and controls the external air source to periodically introduce air, and the pressure of the introduced air is greater than the operating pressure of the pressure valve 34 between the connecting cavity 22 and the bubble hole, so as to clean the inner wall of the tank body 1 and remove the residual materials on the inner wall of the tank body 1.

[0026] The specific workflow is as follows: During operation, materials and microorganisms are put into the tank body 1 from the feed port 12, and then the motor 11 is controlled by the controller to rotate, so that the rotating shaft 2, the connecting rod 3, the mounting plate 4, the cleaning plate 5 and the discharge plate 6 start to rotate synchronously, and the materials and microorganisms entering the tank body 1 are stirred. After that, after the fermentation is completed, the materials in the tank body 1 are discharged from the discharge port 13; During the material discharge process, the discharge plate 6 on the rotating shaft 2 will stir and scrape the bottom surface of the tank body 1, so that the material at the bottom of the tank body 1 is pushed, and the material is discharged from the discharge port 13. At the same time, the cleaning plate 5 rotating synchronously with the rotating shaft 2 will scrape and clean the inner wall of the tank body 1; at the same time, after the material in the tank body 1 is discharged and the tank body 1 is cleaned, the controller will control the external water pump to send clean water into the water spray ring 7 through the water inlet pipe 15, and then spray it on the inner wall of the tank body 1. At this time, the rotating shaft 2 will drive the cleaning plate 5 to rotate along the inner wall of the tank body 1 to clean the inner wall of the tank body 1. At the same time, the clean water sprayed from the water spray ring 7 will temporarily gather at the bottom of the tank body 1, and the rotating discharge plate 6 will stir the clean water at the bottom of the tank body 1 to clean the inner wall of the tank body 1 near the bottom; At the same time, due to the elasticity of the cleaning plate 5 and the hydrophobic layer provided on each component, during the cleaning process, after the cleaning plate 5 scrapes off the residual material on the inner wall of the tank body 1, the residual material can easily slide and fall off from the surface of the cleaning plate 5; At the same time, since there are multiple groups of cleaning plates 5, when there is a relatively large amount of residual material, the material will squeeze the cleaning plates 5, causing the cleaning plates 5 to deform and forming gaps between the cleaning plates 5, so that the cleaned material can pass through the gaps between the cleaning plates 5 and fall to the bottom of the tank body 1; At the same time, since the deformation cavity is formed between the cleaning plates 5 through the elastic membrane 51, during the cleaning process of the residual material on the inner wall of the tank body 1, the deformation cavity is easily blocked by the residual material and deformed, thereby squeezing, vibrating or impacting the material attached to the surface of the cleaning plate 5, and promoting the cleaned residual material to fall off from the cleaning plate 5; When the cleaning plate 5 cleans the inner wall of the tank body 1, the slider 42 will move away from the mounting plate 4 under the action of centrifugal force, and then cooperate with the elastic block 43 and the periodic change of the motor 11 speed, so that the slider 42 will reciprocate in the deformation chamber. At this time, since the slider 42 and the cleaning plate 5 are in contact with each other, when the slider 42 reciprocates, the size of the deformation chamber on both sides of the slider 42 will change, thereby causing pressure changes, so that the cleaning plate 5 and the elastic membrane 51 will deform and vibrate under the action of pressure, and the materials on the surface of the cleaning plate 5 are cleaned; By setting the crossbar 71, the connecting rod 3, the mounting plate 4 and the cleaning plate 5 are sprayed with water for washing; At the same time, when the cleaning plate 5 rotates to the position where the magnetic block 44 is located, the slider 42 is affected by the magnetic attraction of the magnetic block 44, so that the slider 42 quickly rushes to the direction of the magnetic block 44. In this case, the moving speed of the slider 42 is relatively fast, and the pressure change caused by the slider 42 in the deformation chamber is relatively drastic, so that the vibration and deformation of the cleaning plate 5 and the elastic membrane 51 are also relatively drastic, so that the relatively drastic vibration and deformation can promote and accelerate the separation of the residual materials on the cleaning plate 5; Since the cleaning plate 5 is arranged obliquely, when the cleaning plate 5 cleans the inner wall of the tank body 1, the residual materials scraped and cleaned from the inner wall of the tank body 1 by the cleaning plate 5 will slide down along the downward slope of the cleaning plate 5, thereby promoting the separation of the residual materials on the cleaning plate 5; When cleaning the fermentation equipment, the air sent in from the external air source will enter the installation cavity after passing through the air inlet pipe 14, the air path rotary connector 21, and the connecting cavity 22, and then push the movable rod 32 in the installation cavity to extend, so that the cleaning plate 5 is closely attached to the inner wall of the tank body 1; At the same time, during the fermentation process, the external air source does not introduce air or introduces air with lower pressure, so that the pressure in the installation cavity is reduced, so that the movable rod 32 is retracted into the installation cavity under the action of the spring 33. At this time, the installation plate 4 and the cleaning plate 5 will act as stirring blades, and cooperate with the discharge plate 6 to stir the material inside the tank body 1; At the same time, when cleaning the fermentation equipment, the controller will control the external air source to periodically introduce air, so that the pressure in the installation cavity changes periodically, thereby causing the movable rod 32 to reciprocate. In this case, with the rapid extension and retraction of the movable rod 32, the residual materials attached to the installation plate 4 and the cleaning plate 5 are subjected to a greater impact, which promotes the residual materials to separate from the surfaces of the installation plate 4 and the cleaning plate 5. At the same time, since there are multiple groups of connecting rods 3, and the maximum extension lengths of the movable rods 32 of different groups are different, and when the pressure of the air introduced is different, the extension lengths of the movable rods 32 are also different, therefore, during the fermentation process, the controller controls the external air source to change the pressure of the air introduced, so that the distances of the movable rods 32, the mounting plate 4 and the cleaning plate 5 of different groups relative to the rotating shaft 2 are different, so that the materials in different areas of the tank body 1 are stirred; During the fermentation process, when the pressure of the incoming air is less than the operating pressure of the pressure valve 34 between the connecting chamber 22 and the bubble hole, the movable rod 32 can be extended or retracted to complete the stirring of the material. At the same time, when the pressure of the incoming air is greater than the operating pressure of the pressure valve 34 between the connecting chamber 22 and the bubble hole, the movable rod 32 is fully extended, the cleaning plate 5 contacts the inner wall of the tank body 1, and the air is discharged from the bubble hole, supplying sufficient oxygen to the fermentation process, facilitating the rapid reproduction of microorganisms. At the same time, during the cleaning process, the air ejected from the bubble hole will stir the clean water at the bottom of the tank body 1 and generate a large number of bubbles, and use the bubbles to impact the discharge plate 6, or when the clean water filled in the tank body 1 is large, the connecting rod 3, the mounting plate 4, and the cleaning plate 5 are impacted to improve the cleaning effect of the fermentation equipment.
