Description

Technical Field

[0001] This application relates to the field of food production equipment, and in particular to a device for circulating brine for dried tofu. Background Technology

[0002] In the production of dried tofu, the brine is recycled efficiently through scientific management: after braising, it is allowed to settle and separate into layers, skimming off the surface oil and foam, and reusing the clear middle layer; impurities at the bottom are cleaned regularly. It is boiled daily to sterilize and prevent microbial growth, and spices and seasonings are precisely replenished according to the amount of braising to maintain stable flavor. Spice packets are used alternately, replaced on average after three uses to prevent bitterness. The long-term circulating brine requires regular testing of microbial indicators to ensure safety. This process reduces costs while preserving the rich flavor of aged brine, balancing efficiency and quality.

[0003] In the process of circulating the brine for dried tofu, seasonings need to be added and the spice packet needs to be replaced before filtration. The existing brine circulation system filters the brine directly through a filter screen. When there are many impurities, all the impurities need to be filtered through the filter screen, which will cause the filter screen to have high filtration pressure and reduce the filtration quality. Summary of the Invention

[0004] In order to alleviate the filtration pressure on the filter screen and improve the filtration effect of the filter screen in the filtration of dried tofu brine, this application provides a dried tofu brine circulation device.

[0005] The technical solution of the dried tofu brine circulation device provided in this application is as follows:

[0006] A dried tofu brine circulation device includes a support frame, on which a sedimentation tank is fixed. The bottom of the sedimentation tank is connected to a discharge pipe, and a valve is installed on the discharge pipe. A collection box is set below the discharge pipe. A flexible hose is installed inside the sedimentation tank. The bottom of the flexible hose is connected to the discharge pipe. A connecting ring is fixed to the upper end of the flexible hose. A float is set above the connecting ring. Several circumferentially distributed connecting ropes are arranged between the bottom of the float and the connecting ring.

[0007] By adopting the above technical solution, the dried tofu brine that needs to be recycled is placed in a sedimentation tank. Ingredients can be added to the sedimentation tank. After sedimentation for a period of time, the valve is opened. At this time, the float plate floats on the surface of the dried tofu brine, and the upper end of the hose is located below the float plate, which can discharge the dried tofu brine. Moreover, during the discharge of the dried tofu brine, the impurities floating on the surface of the dried tofu brine and the impurities settled at the bottom will not enter the hose, thereby achieving a filtration effect.

[0008] Preferably, a patch is provided on the outer side of the connecting ring.

[0009] By adopting the above technical solution, in the final stage of the discharge of the dried tofu brine, the plate will fall above the bottom impurities, preventing the end of the hose from sinking under the impurities and preventing the impurities from entering the discharge pipe.

[0010] Preferably, the float plate has a locking hole in the middle, two locking plates are connected to the connecting ring, the locking plates have locking tongues on the outside, and a sealing ring is provided at the upper end of the connecting ring.

[0011] By adopting the above technical solution, when no discharge is required, the two clamping plates can be pressed together and the connecting ring can be attached to the lower surface of the float plate. At this time, the clamping tongue will be stuck above the float plate, and the sealing ring will improve the sealing between the connecting ring and the float plate, so that the brine of dried tofu will not enter the hose, thereby preventing impurities from settling in the hose.

[0012] Preferably, the outer side of the card plate is covered with a silicone sleeve, and the outer side of the silicone sleeve is provided with anti-slip texture.

[0013] By adopting the above technical solution, the silicone-coated sleeve will not produce harmful substances that affect food safety, and it can also prevent slippage when squeezing the pallet.

[0014] Preferably, a waste bin is provided on the outside of the collection bin, and two fixing plates are fixed at the upper end of the collection bin. An inclined filter screen is provided on the upper end of the fixing plate, and baffles are provided on the upper end and both sides of the filter screen. The bottom of the filter screen is located above the waste bin.

[0015] By adopting the above technical solution, the brine for dried tofu flows through the discharge pipe to the top of the filter screen, and the liquid falls through the filter screen into the collection box. Meanwhile, the impurities suspended in the brine for dried tofu will fall along the filter screen into the waste box, thus improving the filtration effect.

[0016] Preferably, a plurality of vertical rods are slidably arranged on the fixing plate, the upper end of the vertical rods is fixed to the bottom of the filter screen, and a support spring is sleeved on the outside of the vertical rods. The two ends of the support springs abut against the filter screen and the fixing plate, respectively. A connecting seat is fixed to the upper end of the stop rod, and a vibration motor is installed on the upper end of the connecting seat.

[0017] By adopting the above technical solution, the vibrating motor drives the filter screen to vibrate, and the supporting spring can provide vibration space for the filter screen to vibrate, accelerate the downward movement of impurities, and prevent the filter screen from clogging.

[0018] Preferably, the sedimentation tank has a discharge port on its side, a rotatable cover plate on the outside of the discharge port, a sealing strip on the inside of the cover plate, a connecting plate at the bottom of the cover plate, a fixing bolt threadedly connected to the connecting plate, and a threaded hole at the bottom of the sedimentation tank.

[0019] By adopting the above technical solution, the cover plate can be fixed by tightening the fixing bolt into the threaded hole. Similarly, the cover plate can be opened by unscrewing the fixing bolt, which makes it convenient to clean the sedimentation tank.

[0020] Preferably, a crossbeam is fixed on the support frame, and two lifting cylinders are fixed on the crossbeam. The output shafts of the lifting cylinders face downwards, and the ends of the output shafts are connected to a material bag basket.

[0021] By adopting the above technical solution, the two spice bags can be circulated and soaked under the drive of the lifting cylinder. The two spice bags are used alternately, and each spice bag is replaced after being used multiple times on average, avoiding bitterness caused by long-term soaking.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The float plate suspends the upper end of the hose between the floating and sedimented impurities in the dried tofu brine. When the dried tofu brine is discharged, it can perform preliminary filtration of floating and sedimented impurities, reduce the filtration pressure of subsequent filter screens, and improve filtration efficiency. Moreover, the float plate will descend with the liquid level, so no operator adjustment is required, making it convenient to use. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a device for circulating brine for dried tofu.

[0031] Reference Figures 1-4 A dried tofu brine circulation device includes a support frame 1, on which a sedimentation tank 2 is mounted. A discharge pipe 3 is located at the bottom of the sedimentation tank 2, and a valve 4 is installed on the discharge pipe 3 to control the flow rate. A collection box 9 is placed below the discharge pipe 3, and a waste bin 16 is located on the outside of the collection box 9. Two parallel fixing plates 17 are fixed to the upper end of the collection box 9. A filter screen 18 is arranged obliquely above the fixing plates 17, and multiple vertical rods 20 are evenly distributed below the filter screen 18. The vertical rods 20 slide through the fixing plates 17 and are fitted with support springs 21 to achieve elastic support for the filter screen 18. A stop bar 19 is installed at the top and both sides of the filter screen 18. The top stop bar 19 is connected to a vibration motor 23 via a connecting seat 22, and the bottom of the filter screen 18 extends directly above the waste bin 16. The sedimentation tank 2 is equipped with a hose 5. The lower end of the hose 5 is connected to the discharge pipe 3, and the upper end is fixed by a connecting ring 6. A float plate 7 is suspended above the connecting ring 6 by multiple circumferentially distributed connecting ropes 8, so that the hose 5 can float with the liquid level.

[0032] With the above setup, the brine for the dried tofu, which needs to be recycled, is temporarily stored in the sedimentation tank 2. When needed, seasonings can be added to the tank and the brine can be allowed to settle. After the impurities separate into layers, valve 4 is opened. At this time, the float plate 7 floats with the liquid surface, ensuring that the upper end of the hose 5 is always below the liquid surface. This prevents the foam floating on the surface and the residue settling at the bottom of the tank from entering the hose 5 when the brine is discharged, thus achieving preliminary filtration. The brine flows through the discharge pipe 3 to the top of the inclined filter screen 18. The liquid penetrates the filter screen 18 and falls into the collection box 9, while the suspended impurities slide down the screen surface into the waste box 16 under the combined action of gravity and the vibration of the filter screen 18.

[0033] Reference Figure 2 A plate 10 is added to the outside of the connecting ring 6, and a locking hole 11 is opened in the center of the float plate 7. Two locking plates 12 are symmetrically fixed on the connecting ring 6. The end of the locking plate 12 is provided with a locking tongue 13. A sealing ring 14 is embedded in the top of the connecting ring 6 to ensure liquid tightness. The outer layer of the locking plate 12 is covered with a silicone sleeve 15 with anti-slip texture.

[0034] With the above setup, in the final stage of the dried tofu brine discharge, impurities at the bottom of the sedimentation tank 2 gradually accumulate. At this time, the plate 10 descends with the liquid level to the top of the impurity layer, forming a physical barrier to effectively prevent the end of the hose 5 from sinking into the impurity pile, thereby preventing the bottom sediment from flowing back into the discharge pipe 3. During sedimentation, the operator can press the elastic clamping plates 12 on both sides of the connecting ring 6 inward, so that the clamping tongue 13 passes over the edge of the clamping hole 11 and is clamped on the upper surface of the float plate 7, achieving a tight fit between the connecting ring 6 and the float plate 7. At this time, the silicone sealing ring 14 embedded in the top of the connecting ring 6 is deformed by pressure, filling the micro gaps on the contact surface and forming a liquid-tight protection, ensuring that the brine cannot seep into the inside of the hose 5, preventing impurities from accumulating and clumping inside the pipe, and ensuring the continuous clean operation of the circulation system.

[0035] Reference Figure 4 The sedimentation tank 2 has a discharge port 24 on its side wall. A cover plate 25 that can be rotated around an axis to open and close is provided on the outside of the discharge port 24. A sealing strip 26 is embedded in the inside of the cover plate 25 to ensure the sealing when closed. A connecting plate 27 extends from the bottom of the cover plate 25. The connecting plate 27 has a threaded through hole. The cover plate 25 is locked securely by tightening it with the threaded hole 29 at the bottom of the sedimentation tank 2 through the fixing bolt 28, which effectively prevents the brine from leaking.

[0036] With the above settings, the cover plate 25 can be opened when cleaning the sedimentation tank 2 to facilitate sewage discharge.

[0037] Reference Figure 1 A crossbeam 30 is fixed on the support frame 1, and two lifting cylinders 31 are fixed on the crossbeam 30. The output shaft of the lifting cylinder 31 faces downward, and the end of the output shaft is connected to a material bag basket 32.

[0038] With the above setup, the two spice bag baskets 32 can achieve cyclic soaking of the spice under the drive of the lifting cylinder 31. The two spice bags are used alternately, and each spice bag is replaced after being used multiple times on average, avoiding bitterness caused by long-term soaking.

[0039] The implementation principle of this application is as follows:

[0040] The brine for dried tofu that needs to be recycled is temporarily stored in the sedimentation tank 2. When needed, seasonings can be added to the tank and the brine can be allowed to settle. During sedimentation, the clamping plates 12 on both sides of the connecting ring 6 can be pressed inward, so that the clamping tongue 13 passes over the edge of the clamping hole 11 and is clamped on the upper surface of the float plate 7, achieving a tight fit between the connecting ring 6 and the float plate 7, preventing impurities from entering the hose 5. After the impurities have separated into layers, the valve 4 is opened and the clamping plates 12 are reset. At this time, the float plate 7 floats with the liquid surface, ensuring that the upper end of the hose 5 is always below the liquid surface, so that the foam floating on the surface and the residue settling at the bottom of the tank when the brine is discharged cannot enter the hose 5, achieving preliminary filtration. The brine flows through the discharge pipe 3 to the top of the inclined filter screen 18. The liquid penetrates the filter screen 18 and falls into the collection box 9, while the suspended impurities slide down the screen surface to the waste box 16 under the combined action of gravity and the vibration of the filter screen 18.

[0041] In addition, the two material bag baskets 32 can achieve cyclic soaking under the drive of the lifting cylinder 31. The two material bags are used alternately, and each spice bag is replaced after being used multiple times on average to avoid bitterness caused by long-term soaking. Moreover, when cleaning the sedimentation tank 2, the cover plate 25 can be opened for easy sewage discharge.

[0042] In summary, this device can separate the brine of dried tofu into sedimentation layers, discharge the middle layer of brine through the hose 5, and then filter and collect it through the filter screen 18, thereby reducing the filtration pressure of the filter screen 18 and improving the filtration effect.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
