Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, the meaning of "plurality" is three or more.

[0026] Figure 1-Figure 4 A slag removal device for tofu processing provided in an embodiment of the present application comprises: a base frame 1, an extrusion assembly 7, wherein a column shell 2 and a grinding assembly 5 are fixedly arranged on the base frame 1, a spiral feeding assembly 3 is arranged at one end of the column shell 2, an extrusion assembly 7 and a secondary filtering and screening assembly 8 are arranged at the other end of the column shell 2, and a primary filtering and screening assembly 4 is arranged in the column shell 2, a discharge port of the grinding assembly 5 extends into the primary filtering and screening assembly 4, a liquid outlet 6 is arranged on the column shell 2 at the lower end of the primary filtering and screening assembly 4, and the extrusion assembly 7 comprises a fixing seat 71 fixed to the column shell 2, A motor 72 is provided on one side of the fixed seat 71, and the fixed seat 71 is fixed to the cam rotating piece 74 through a driving shaft 73. The driving shaft 73 is fixedly provided at the output end of the motor 72. A connecting rod 76 is eccentrically rotatably provided in the cam rotating piece 74. A push rod 77 is hingedly provided on the connecting rod 76. A prefabricated guide cylinder 75 is fixedly provided on the fixed seat 71. The push rod 77 is movably provided in the prefabricated guide cylinder 75. A cylindrical plug 78 is fixedly provided on the side of the push rod 77 away from the prefabricated guide cylinder 75. The cylindrical plug 78 is vertically movably provided in the secondary filtration and screening assembly 8.

[0027] Based on the above technical solution, the beans are placed in the grinding assembly 5, and then the grinding assembly 5 is started, and the spiral feeding assembly 3, the primary filtering and screening assembly 4 and the extruding assembly 7 are started at the same time. The soy milk filtered by the primary filtering and screening assembly 4 enters the collecting assembly along the liquid outlet 6 to be collected, and the bean dregs preliminarily separated by the primary filtering and screening assembly 4 are sent to the secondary filtering and screening assembly 8, and the motor 72 is started. During the rotation of the motor 72, the cam rotating piece 74 is deflected, so that the connecting rod 76 drives the push rod 77 to move in the vertical direction in the prefabricated guide cylinder 75. The push rod 77 drives the cylindrical plug 78 to move up and down to cooperate with the secondary filtering and screening assembly 8, so that the soy milk and bean dregs in the preliminarily separated bean dregs can be separated again.

[0028] On the basis of the above technical scheme, the present device first filters the slurry ground by the grinding component 5 through the rotation of the primary filtering and screening component 4, so that the initially separated dregs are transported to the secondary filtering and screening component 8 by the spiral feeding component 3, and the dregs are squeezed and filtered through the cooperation of the extrusion component 7, so that the residual soy milk in the dregs is screened. The staged treatment method can greatly reduce the liquid content in the dregs, which is beneficial to the subsequent treatment of the dregs (such as drying, fermentation, etc.) and improves the efficiency of the entire production process.

[0029] In one possible implementation, the spiral feeding assembly 3 includes a driving unit 31 fixedly mounted on the base frame 1, an auger 32 being mounted at the output end of the driving unit 31, the auger 32 being rotatably mounted in the primary filtering and screening assembly 4, the auger 32 being capable of transporting the bean dregs preliminarily separated by the primary filtering and screening assembly 4 to the secondary filtering and screening assembly 8, so as to prevent the accumulation of bean dregs and affect the filtration of the slurry.

[0030] In one possible implementation, a fence is installed on the primary filtering and screening component 4 near the discharge port of the grinding component 5, and a self-driving rotating drum is provided in the primary filtering and screening component 4. The fence can prevent the initially separated bean dregs from being exposed from the side of the drum away from the extrusion component 7, and prevent the initially separated bean dregs from being mixed with the separated soy milk again to affect the purity of the soy milk. During the rotation of the drum, the slurry ground by the grinding component 5 can achieve initial separation of the slurry and the bean dregs, and the slurry is discharged along the liquid outlet 6, while the initially separated bean dregs enter the secondary filtering and screening component 8.

[0031] In a possible implementation, a plurality of water injection nozzles are disposed in the column shell 2 and the prefabricated guide tube 75 .

[0032] Through the above technical solution, after the pressing work is completed, water is injected into the grinding component 5, and the water injection nozzle injects water into the primary filtering and screening component 4 and the prefabricated guide cylinder 75. During the rotation of the rotating drum and the up and down movement of the cylindrical plug 78, each component in the device can be fully cleaned, which helps to prevent cross-contamination of food between different batches, avoids the growth of bacteria and microorganisms, and improves food safety.

[0033] In one possible implementation, the secondary filtering and screening component 8 includes: a base shell 81, which is detachably fixedly connected to the column shell 2, and a first empty bin 82 and a second empty bin 83 are opened in the base shell 81, a screening plate 86 is fixedly provided at the connection between the first empty bin 82 and the second empty bin 83, and the second empty bin 83 is connected to the branch channel 84, and the lower end of the first empty bin 82 is connected to the slag outlet 85, and a valve body is installed in the slag outlet 85. When the valve body is closed, soy milk can flow out from the screening plate 86 and be collected at the branch channel 84. After the valve body is opened, the pressed bean dregs can be discharged from the slag outlet 85.

[0034] In one possible implementation, the outer diameter of the cylindrical plug 78 is equal to the inner diameter of the first empty bin 82, and the cylindrical plug 78 is movably disposed in the first empty bin 82. After closing the valve body, the cylindrical plug 78 can cooperate with the valve body to squeeze the initially separated okara during the up and down movement in the first empty bin 82, thereby screening the soy milk remaining in the okara.

[0035] In a possible implementation, a plurality of through holes are provided on the rotating drum and the sieve plate 86 , and filter cloths are detachably installed in the rotating drum and the sieve plate 86 .

[0036] By adopting the above technical solution, the slurry after the beans are ground by the grinding assembly 5 is sent to the drum. During the rotation of the drum, the filter cloth can perform preliminary separation of the soy milk and the bean dregs. The filtered soy milk enters the liquid outlet 6 along the through holes on the filter cloth and the drum. The preliminarily separated bean dregs then enter the first empty bin 82. After the cylindrical plug 78 cooperates with the valve body, the bean dregs are pressed. The pressed slurry can be filtered through the filter cloth and then enter the diversion channel 84 along the through holes of the screening plate 86.

[0037] In a possible implementation, the liquid outlet 6 and the branch channel 84 are respectively connected to the collecting component, so that the soy milk filtered by the filter cloth is collected in the collecting component along the liquid outlet 6 and the branch channel 84 for the next process.

[0038] Working principle:

[0039] First, fix the filter cloth in the drum and the screening plate 86, close the valve body on the secondary filtering and screening component 8, then put the beans into the grinding component 5 and start the grinding component 5, and at the same time start the spiral feeding component 3, the primary filtering and screening component 4 and the extruding component 7, the soybean milk filtered by the filter cloth on the primary filtering and screening component 4 enters the collecting component along the liquid outlet 6 to be collected, and the initially separated bean dregs enter the first empty bin 82 along the drum and the auger 32, and under the driving action of the motor 72, the cylindrical plug 78 squeezes the bean dregs, and the soybean milk is sequentially discharged from the filter cloth, the primary filtering and screening component 4, and the extruding component 7. The screening plate 86 enters the branch channel 84 and finally enters the collecting assembly to be collected. At this time, the valve body is opened, and the pressed bean dregs are discharged through the dregs outlet 85. During the rising process of the cylindrical plug 78, the valve body is closed and the above steps are repeated until the pressing work is completed. After the pressing work is completed, the valve body is normally open, and water is injected into the grinding assembly 5 and the water injection nozzle is used to inject water into the primary filtering and screening assembly 4 and the prefabricated guide cylinder 75. During the rotation of the drum and the up and down movement of the cylindrical plug 78, each component in the device is fully cleaned.
