Abstract
Description
Technical Field
[0001] This utility model relates to the field of dried bean curd processing technology, specifically a dried bean curd processing pulp and residue separator. Background Technology
[0002] Tofu skin (yuba) is a soy product made from soybeans. It is a popular traditional Hakka food and a common food ingredient in Chinese communities. It has a rich soybean aroma and a unique texture that other soy products do not have. The production of tofu skin involves several steps, including selecting raw materials, peeling, soaking soybeans, grinding, separating the pulp and residue, boiling the pulp, filtering the pulp, and picking out the tofu skin. Most existing separation methods use filter screens, which are inefficient and contain a lot of liquid in the residue, resulting in significant waste. In addition, the temperature of the pulp and residue drops rapidly during filtration, causing the starch inside the pulp and residue to become viscous and difficult to separate from the residue. As a result, the separation efficiency is low and the separation quality is poor. Utility Model Content
[0003] The purpose of this invention is to provide a pulp and residue separator for dried bean curd processing, so as to solve the problems of low pulp and residue separation and filtration efficiency and incomplete separation mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a slurry-residue separator for dried bean curd processing, comprising a mounting base plate, a shock-absorbing rubber pad fixedly mounted on the outer surface of the mounting base plate, and a separation box fixedly mounted on the outer surface of the shock-absorbing rubber pad. An upper frame is fixedly mounted on the outer surface of the separation box at the end away from the mounting base plate. A motor is fixedly mounted on the outer surface of the separation box, and the motor and the separation box are concentrically designed. The outer surface of the separation box is penetrated by the output end of the motor. A support platform is fixedly mounted on the outer surface of the output end of the motor, and the support platform and the motor are concentrically designed. A locking mechanism is provided between the support platform and the separation box. Through the locking mechanism, the slurry and residue discharged into the separation box can be rotated to achieve more thorough separation.
[0005] Preferably, the engaging mechanism includes: a sieve barrel, with handles on both outer surfaces of the sieve barrel, and a plug-in block fixedly installed on one outer surface of the sieve barrel. The sieve barrel and the plug-in block are concentrically designed, and the plug-in block engages with the support platform. The sieve barrel is located inside the separation box, and a guide frame is fixedly installed on the outer surface of the separation box. A rolling wheel is rotatably installed on the side surface of the guide frame, and the outer surface of the rolling wheel is in contact with the side surface of the rolling wheel.
[0006] Using the above technical solution, the processed slurry and residue can be fed into the inside of the sieve bucket through the conveying pipe, allowing the soy milk and residue to be separated. After the sieve bucket is fixed, the motor is started, and the rotation of the motor drives the support platform to rotate, which in turn drives the interlocking blocks to rotate, allowing the sieve bucket to rotate along with it. The rolling wheels support the sieve bucket, allowing it to rotate more smoothly and preventing it from swaying and causing huge vibrations. The centrifugal force generated by the rotation of the sieve bucket separates the remaining soy milk. After the separation is complete, the entire sieve bucket can be removed, and the remaining soy residue inside can be used for processing other foods, making the separation of soy milk and residue more thorough and reducing the waste of soy milk.
[0007] Preferably, a multi-section electric push rod is fixedly installed on the outer surface of the upper frame, and the multi-section electric push rod and the motor are designed concentrically. A rotating and pushing mechanism is provided between the multi-section electric push rod and the screen barrel. The liquid of the slurry and slag put into the screen barrel can be pressed out by the rotating and pushing mechanism, thereby accelerating the liquid separation speed of the slurry and slag.
[0008] By adopting the above technical solution, the pressing plate is moved by pushing out the multi-section electric push rod, so that the pressing plate can be pushed into the inside of the screen bucket. The pressing plate squeezes the soybean residue, allowing the soybean milk inside the residue to be further squeezed out, thereby improving the efficiency of processing and separation.
[0009] Preferably, the rotating pushing mechanism includes: a pressing plate, which is rotatably mounted on the outer surface of the output end of the multi-section electric push rod, and the side surface of the pressing plate is in contact with the outer surface of the screen barrel.
[0010] By using the above technical solution, the soybean residue inside the sieve can be squeezed and gathered together by the squeezing of the squeezing plate, making the sieve more stable when rotating to separate soybean milk, and the sieve is fixed to the outer surface of the support platform by the pushing of the squeezing plate.
[0011] Preferably, a multi-section lifting electric push rod is fixedly installed on the outer surface of the separation box, and the output end of the multi-section lifting electric push rod passes through the outer surface of the separation box. A lifting unloading plate is fixedly installed on the output end of the multi-section lifting electric push rod, and an opening is provided on one side of the lifting unloading plate. The outer surface of the lifting unloading plate is in contact with the outer surface of the mounting and fixing base plate.
[0012] Using the above technical solution, after separating the soybean milk and soybean residue, the lifting and lowering plate can be moved by pushing the multi-section electric push rod. This allows the lifting and lowering plate to move the screen bucket, enabling it to rise out of the separation box. The screen bucket can then be removed from the opening of the lifting and lowering plate, facilitating its placement into the separation box and its removal from the box. This process also facilitates the removal of the soybean residue, reducing the labor intensity for workers.
[0013] Preferably, a slurry discharge port is provided on one outer surface of the separation box, and the interior of the separation box is designed to be inclined. A liquid discharge hose is fixedly installed on the outer surface of the slurry discharge port of the separation box.
[0014] Using the above technical solution, the soy milk separated by centrifugation will be thrown into the interior of the separation tank and flow to the lowest point through the inclined surface. Then, the soy milk will enter the interior of the liquid discharge hose through the discharge port and be discharged into the container for collection. At the same time, when cleaning after use, you only need to remove the sieve bucket for cleaning, and use a high-pressure water gun or other items to rinse the interior of the separation tank for easy cleaning, reducing the difficulty of cleaning after use.
[0015] Preferably, a steam heating pipe is fixedly installed inside the separation box, and the input end of the steam heating pipe penetrates through the side surface of the separation box. The separation box and the steam heating pipe are concentrically designed. The outer surface of the steam heating pipe is uniformly provided with through holes, and the outer surface of the steam heating pipe does not fit against the outer surface of the screen barrel.
[0016] Using the above technical solution, after the pulp residue is discharged into the screen barrel, in order to prevent the pulp residue from cooling down too quickly, high-temperature steam can be sprayed out through the steam heating pipe, so that the high-temperature steam can pass through the screen barrel to heat the pulp residue, so that the temperature of the pulp residue will not drop too quickly and cause the starch to become viscous and difficult to separate.
[0017] Compared with the prior art, the beneficial effects of this utility model are: This bean curd processing pulp and residue separator:
[0018] 1. When separating soy milk and soy residue, the processed soy milk and soy residue are simply fed into the screen bucket through a moving pipe. The soy milk and soy residue in the soy milk and soy residue are then separated through the screen bucket. The screen bucket is then squeezed and fixed, and the rotation of the motor drives the support platform to rotate. The support platform can drive the screen bucket to rotate through the plug-in block. The centrifugal force generated by the rotation of the screen bucket accelerates the separation of soy milk and soy residue, improves the separation effect of soy milk and soy residue, and shortens the separation time.
[0019] 2. After the pulp residue is put into the screen bucket, the multi-section electric push rod can be activated to push the extrusion plate outward. The extrusion plate can be pushed into the screen bucket and squeeze the pulp residue, so that the soy milk in the pulp residue can be further separated. The pulp residue can be gathered together to reduce the chance of vibration and sloshing when the screen bucket rotates. At the same time, the screen bucket can be squeezed and fixed to the outer surface of the support platform, which can further separate the soy milk and soy residue. It can also ensure that the screen bucket can be fixed and will not deflect or vibrate excessively when rotating.
[0020] 3. Once the pulp and residue separation is complete, the multi-section electric actuator can be activated. Pushing the multi-section electric actuator will move the lifting feed plate, allowing it to contact the outer surface of the screen bucket. This allows the screen bucket to be moved along with the sieve, making it easy to remove from the separation box. Tapping the screen bucket will then remove and separate the soybean residue inside. This facilitates easy separation of the screen bucket from the separation box, making subsequent cleaning and rinsing of both the separation box and the screen bucket easier and reducing the labor intensity when removing the soybean residue.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-6 This utility model provides a technical solution: a pulp and residue separator for dried bean curd processing, including a mounting base plate 1, a shock-absorbing rubber pad 2 fixedly mounted on the outer surface of the mounting base plate 1, and a separation box 3 fixedly mounted on the outer surface of the shock-absorbing rubber pad 2. An upper frame 6 is fixedly mounted on the outer surface of the separation box 3 away from the mounting base plate 1. A motor 5 is fixedly mounted on the outer surface of the separation box 3, and the motor 5 and the separation box 3 are concentrically designed. The outer surface of the separation box 3 is penetrated by the output end of the motor 5. A support platform 15 is fixedly mounted on the outer surface of the output end of the motor 5, and the support platform 15 and the motor 5 are concentrically designed. A locking mechanism is provided between the support platform 15 and the separation box 3. Through the locking mechanism, the pulp and residue discharged into the separation box 3 can be rotated to make the pulp and residue more thoroughly separated.
[0030] The vibration damping rubber pad 2 can reduce the noise generated by the vibration transmitted to the mounting base plate 1 when the separation box 3 is rotating, and can also reduce the vibration generated when the separation box 3 is running, and reduce the loosening of screws and other connections caused by vibration.
[0031] The engaging mechanism includes: a screen barrel 11, with handles on both outer surfaces of the screen barrel 11, and a plug-in block 14 fixedly installed on one outer surface of the screen barrel 11. The screen barrel 11 and the plug-in block 14 are concentrically designed, and the plug-in block 14 engages with the support platform 15. The screen barrel 11 is located inside the separation box 3. A guide frame 12 is fixedly installed on the outer surface of the separation box 3, and a rolling wheel 13 is rotatably installed on the side surface of the guide frame 12. The outer surface of the rolling wheel 13 is in contact with the side surface of the rolling wheel 13.
[0032] When filtration and separation of slurry are required, the slurry and residue are simply discharged into the screen 11 through a movable pipe, allowing the soy milk to be filtered out from the screen 11. The screen 11 is then fixed in place, and the rotation of the motor 5 drives the support platform 15 to rotate. The support platform 15 drives the interlocking plug 14 to rotate, causing the screen 11 to rotate along with it. The rolling wheels 13 support the screen 11, making its rotation more stable and reducing the vibration caused by the screen 11's deflection. This allows the screen 11 to rotate more smoothly, and the centrifugal force enables faster separation of slurry and residue, reducing the amount of residual soy milk in the slurry and improving the filtration efficiency of the slurry.
[0033] The outer surface of the upper frame 6 is fixedly installed with a multi-section electric push rod 7, and the multi-section electric push rod 7 and the motor 5 are designed concentrically. A rotating pushing mechanism is set between the multi-section electric push rod 7 and the screen barrel 11. The liquid of the slurry and slag put into the screen barrel 11 can be pressed out by the rotating pushing mechanism, thereby accelerating the liquid separation speed of the slurry and slag.
[0034] The pressing of the multi-section electric push rod 7 can drive the extrusion plate 8 to move away from the upper frame 6, allowing the extrusion plate 8 to be pushed into the screen barrel 11. The extrusion of the extrusion plate 8 can squeeze the pulp residue inside the screen barrel 11, allowing the soy milk in the pulp residue to be squeezed out, so that the pulp residue can be further separated, thereby improving the separation efficiency of pulp residue.
[0035] The rotating and pushing mechanism includes: a pressing plate 8, which is rotatably mounted on the outer surface of the output end of the pressing multi-section electric push rod 7, and the side surface of the pressing plate 8 is in contact with the outer surface of the screen barrel 11.
[0036] The slurry residue is squeezed together by the extrusion plate 8, preventing uneven distribution of slurry residue during rotation of the screen barrel 11 and ensuring smoother rotation. The extrusion plate 8 also facilitates the fixing of the screen barrel 11 to the support platform 15, allowing the screen barrel 11 to be separated from the separation box 3. After use, the separation box 3 can be separated from the screen barrel 11 for easy cleaning of the interior of both the screen barrel 11 and the separation box 3.
[0037] A lifting multi-section electric push rod 9 is fixedly installed on the outer surface of the separation box 3, and the output end of the lifting multi-section electric push rod 9 passes through the outer surface of the separation box 3. A lifting unloading plate 10 is fixedly installed on the output end of the lifting multi-section electric push rod 9, and an opening is provided on one side of the lifting unloading plate 10. The outer surface of the lifting unloading plate 10 is in contact with the outer surface of the mounting and fixing base plate 1.
[0038] After the slurry and slag separation is completed, the multi-section electric actuator 7 is pressed down to retract, which drives the extrusion plate 8 to separate from the screen barrel 11. Then, the multi-section electric actuator 9 is activated to push the lifting feed plate 10 to rise, so that the lifting feed plate 10 can stably lift the screen barrel 11, allowing the screen barrel 11 to rise from the separation box 3 and be easily lowered into the separation box 3. This makes it easy to take out and put in the screen barrel 11. The guide frame 12 can guide the screen barrel 11, so that the screen barrel 11 can enter the separation box 3 more smoothly. At the same time, it can reduce the labor intensity of workers when taking out and putting in the separation box 3.
[0039] A slurry discharge port is provided on one side of the outer surface of the separation box 3, and the interior of the separation box 3 is designed to be inclined. A liquid discharge hose 4 is fixedly installed on the outer surface of the slurry discharge port of the separation box 3.
[0040] When the pressing plate 8 squeezes the pulp residue in the screen barrel 11 and rotates with the screen barrel 11, the soy milk in the pulp residue will be discharged into the separation box 3. The inclined design of the separation box 3 allows the soy milk to be discharged more smoothly from the discharge port, so that the soy milk can be discharged into the storage container through the liquid discharge hose 4. At the same time, when cleaning is required, the debris washed down can also be easily discharged from the separation box 3.
[0041] The separation box 3 is fixedly installed with a steam heating pipe 16, and the input end of the steam heating pipe 16 penetrates the side surface of the separation box 3. The separation box 3 and the steam heating pipe 16 are concentrically designed. The outer surface of the steam heating pipe 16 is evenly provided with through holes, and the outer surface of the steam heating pipe 16 is not in contact with the outer surface of the screen barrel 11.
[0042] By using the steam heating pipe 16, the temperature drop of the pulp residue can be slowed down, making the starch in the pulp residue less likely to become sticky. Steam can be passed through the screen 11 to heat the pulp residue, reducing the temperature drop of the pulp residue in the screen 11 and making it easier for the starch to separate from the pulp residue.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
