Description

Technical Field

[0001] The invention relates to the technical field of fermented bean curd production, and in particular to a multi-strain flavored fermented bean curd coupled preparation device and process. Background Art

[0002] Fermented bean curd is a food made through a specific fermentation process. The main raw material is fresh old bean curd, and the auxiliary materials include bean curd koji, liquor, salt, chili powder, pepper powder, five-spice powder and other seasonings. The fermented bean curd blocks are soaked in high-proof liquor to increase its flavor and prevent contamination by bacteria. Then, salt, chili powder, pepper powder, five-spice powder and other seasonings are mixed evenly in appropriate proportions, and the seasonings are evenly coated on all four sides of the bean curd. During the fermentation process of fermented bean curd, due to the action of microorganisms (such as Mucor), the protein in tofu will be broken down into small molecular peptides and amino acids. These changes make the taste of fermented bean curd more delicate and soft, and the texture gradually becomes soft. Therefore, in the traditional flour coating operation, the powder and tofu are put into the mixing equipment together for mixing and flour coating. The propeller and impeller type agitators will generate greater shear force and impact force when rotating at high speed, which can easily cause the tofu blocks to break. Summary of the invention

[0013] In addition, the present invention also proposes a multi-strain flavored fermented bean curd coupled preparation process, which is applied to the multi-strain flavored fermented bean curd coupled preparation device, and is characterized in that the preparation method comprises the following steps: S1.

After the powder coating is completed, the restriction of the block on the upper net bag and the lower net bag is released and the lower net bag is removed, and the fermented bean curd is taken out of the upper net bag, and the fermented bean curd is prepared.

[0014] In summary, due to the use of the above-mentioned technology, a multi-strain flavored fermented bean curd coupled preparation device and process, the beneficial effects of the present invention are: 1. Through the provided mixing chamber and scattering mechanism, when the powder placing chamber rotates driven by the power source, the gear meshes with the gear ring and rotates along with the rotation of the powder placing chamber. At this time, the gear cooperates with the spiral blade base and the mounting seat to drive the spiral blade to rotate inside the straight cylinder. The powder in the powder placing chamber enters the straight cylinder through the opening at the bottom of the straight cylinder, and rises to the sleeve under the drive of the spiral blade, and is scattered from above the upper net bag and the lower net bag, so that the powder can be evenly contacted with the fermented bean curd. In the process of coating the powder, except for turning the fermented bean curd over by swinging the upper net bag and the lower net bag, the fermented bean curd will not contact with other hard structures again, avoiding the risk of crushing the fermented bean curd due to the extrusion and shearing effect caused by stirring, thereby reducing the generation of broken fermented bean curd and improving the integrity of the fermented bean curd. 2. Through the air supply mechanism, the crankshaft can push the piston cavity to move inside the piston through the connecting rod. In order to avoid inhaling dust, an air inlet is provided on the outer wall of the piston, and an air supply device is provided in the top chamber, and the air supply device is connected to the air inlet of the piston. As the connecting rod pulls the piston cavity, air is sucked into the piston through the air supply device. When the connecting rod pushes the piston cavity, the air passes through the piston to the air supply nozzle and is ejected. During the ejection process, the air flow velocity increases to form a stronger jet. After contacting the powder thrown from the spray port, it helps to blow the powder away and make it more evenly distributed in the powder placement cavity, thereby achieving the purpose of improving the uniformity of powder coating.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology in the embodiments of the present invention, a multi-strain flavored fermented bean curd coupling preparation device and process. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In order to solve the problem that propeller-type and impeller-type stirrers generate large shear force and impact force when rotating during the flour coating operation using stirring equipment, which easily leads to the breakage of tofu blocks, the present invention proposes a multi-strain flavored fermented bean curd coupling preparation device, such as Figure 1 - Fig.12 As shown: The preparation device 10 includes a tank body 12, a power source 11 and a top cover 13 installed on the tank body 12, a lifting feeding mechanism 20 is arranged on the top cover 13, and the feeding mechanism 20 includes an upper net bag 21 and a lower net bag 22 for placing fermented bean curd and having holes on the surface; like Figure 2 , Figure 4 and Fig.11 As shown, an electric telescopic rod 131 is provided on the top of the top cover 13, and the feeding mechanism 20 further includes a combination rod 24 installed on the output end of the electric telescopic rod 131, and a combination frame 23 is provided at the end of the combination rod 24, and the upper net bag 21 and the lower net bag 22 are installed on the combination frame 23 through a locking mechanism 70; The locking mechanism 70 includes a semicircular first plug rod 71 and a second plug rod 72 disposed on both sides of the upper net bag 21 and the lower net bag 22, and the inner walls of the first plug rod 71 and the second plug rod 72 are both provided with positioning rails 73, and a semicircular clamping block 74 is rotatably embedded on the positioning rail 73. When the clamping block 74 is embedded on the positioning rail 73 disposed inside the first plug rod 71 and the second plug rod 72 at the same time, the first plug rod 71 and the second plug rod 72 are combined into a complete circle; The assembly frame 23 is provided with limiting grooves 231 on both sides for the first insertion rod 71 and the second insertion rod 72 to be inserted; When it is necessary to place the fermented bean curd, the net bag 21 needs to be placed in the assembly frame 23, and the first insertion rod 71 is inserted into the limiting groove 231, and the block 74 is rotated and installed in the first insertion rod 71 in cooperation with the positioning rail 73, and the fermented bean curd can be placed in the net bag 21; After the fermented bean curd is placed, the lower net bag 22 is also placed in the assembly frame 23, and the second plug rod 72 is inserted into the limiting groove 231 and fits with the first plug rod 71. At this time, the clamping block 74 is rotated to make the clamping block 74 rotate and be embedded in the positioning rail 73 set in the first plug rod 71 and the second plug rod 72 at the same time. The first plug rod 71 and the second plug rod 72 are connected and combined into a complete circle through the clamping block 74 and cannot be separated. The fermented bean curd is placed; The upper net bag 21 and the lower net bag 22 can be rotated in a biased manner in the limiting groove 231 by the first insertion rod 71 and the second insertion rod 72. The upper net bag 21 and the lower net bag 22 can be swung back and forth to help the fermented bean curd to turn over. In order to fix the positions of the first plug rod 71 and the second plug rod 72, an abutting block 75 abutting against the first plug rod 71 and the second plug rod 72 is provided at the opening of the limiting groove 231, and a retractable latch 76 that penetrates the assembly frame 23 is provided on the abutting block 75. After the abutting block 75 is inserted into the limiting groove 231, its own position is fixed by the latch 76, and at the same time, it abuts against the first plug rod 71 and the second plug rod 72, thereby achieving the purpose of limiting the position of the first plug rod 71 and the second plug rod 72, so that the first plug rod 71 and the second plug rod 72 cannot be moved out of the limiting groove 231 and cannot rotate in the limiting groove 231; After the top cover 13 is rotated to close, the electric telescopic rod 131 is started, so that the electric telescopic rod 131 drives the upper net bag 21 and the lower net bag 22 to descend to the processing position through the combination rod 24 and the combination frame 23.

[0019] The tank body 12 is provided with a mixing chamber 30, such as Figure 3 As shown, the mixing chamber 30 includes a rotatable powder placement chamber 31 connected to the output end of the power source 11, and powder is stored in the powder placement chamber 31; The mixing chamber 30 further includes a slide rail 33 disposed at the bottom end of the inner wall of the tank body 12 and a slide table 32 disposed on the powder placement chamber 31; The powder placement chamber 31 is composed of two cylindrical parts with different diameters. The junction of the two parts forms a step-shaped transition area. The slide 32 is arranged at the bottom of the transition area and is slidably embedded on the slide rail 33. Through this design, when the power source 11 is started, the powder placement chamber 31 can drive the slide 32 to rotate under the restriction of the slide rail 33, thereby preventing the powder placement chamber 31 from shifting during rotation. At the same time, the upper net bag 21 and the lower net bag 22 descend to make the fermented bean curd close to the powder and wait for the powder coating operation to begin.

[0020] A scattering mechanism 40 is installed on the inner edge of the powder placement chamber 31. Preferably, four scattering mechanisms 40 are provided so that the scattering amount of the powder can cover the entire inside of the powder placement chamber 31. Figure 3 , Figure 5-Figure 8 As shown, the scattering mechanism 40 includes a straight cylinder 41 installed on the powder placement chamber 31, a spiral blade 42 rotatably arranged in the straight cylinder 41, and a sleeve 43 located at the top of the straight cylinder 41. An opening for powder to enter is arranged at the bottom of the straight cylinder 41. The powder entering the straight cylinder 41 is sent to the sleeve 43 through the spiral blade 42. The straight cylinder 41 is arranged through the transition area of ​​the powder placement chamber 31, the bottom of the spiral blade 42 passes through the transition area and the top is rotatably connected to the sleeve 43; The scattering mechanism 40 further includes a spiral blade base 44 disposed at the bottom of the spiral blade 42 and a mounting seat 45 meshingly connected to the spiral blade base 44, and the slide 32 is rotatably connected to the bottom of the mounting seat 45; A gear 46 is sleeved and installed between the spiral blade base 44 and the mounting seat 45, and a gear ring 47 meshing with the gear 46 is installed on the inner wall of the tank body 12; When the powder placement chamber 31 rotates driven by the power source 11, the gear 46 meshes with the gear ring 47 and rotates as the powder placement chamber 31 rotates. At this time, the gear 46 cooperates with the spiral blade base 44 and the mounting seat 45 to drive the spiral blade 42 to rotate inside the straight cylinder 41. The powder in the powder placement chamber 31 enters the straight cylinder 41 through the opening opened at the bottom of the straight cylinder 41, and rises to the sleeve 43 driven by the spiral blade 42, and is thrown out from above the upper net bag 21 and the lower net bag 22, so that the powder can be evenly in contact with the fermented bean curd. During the powder coating process, except for turning the fermented bean curd over by swinging the upper net bag 21 and the lower net bag 22, the fermented bean curd will not come into contact with other hard structures again, avoiding the risk of the fermented bean curd being broken due to the extrusion and shearing effect caused by stirring, thereby reducing the production of broken fermented bean curd and improving the integrity of the fermented bean curd.

[0021] At the same time, compared with the traditional method of placing the fermented bean curd in a container full of powder and rolling it to coat the powder, the use of spiral blades 42 to transport the powder to the top for scattering prevents the broken fermented bean curd from remaining in the container to soak the powder. Even if the powder is damp due to other factors, the agglomerated wet powder cannot be transported by the spiral blades 42. This is because the wet powder particles have poor fluidity and are easily aggregated into clumps. The clumps of powder are easy to roll down on the spiral blades 42 and cannot reach the top. Therefore, the setting of the spiral blades 42 also achieves the purpose of screening the damp powder, thereby avoiding uneven pickling due to damp powder.

[0022] In order to further improve the uniformity of powder scattering, Figure 8-Figure 10 As shown, the sleeve 43 includes a spray port 431 connected to the straight cylinder 41, a top chamber 432 located above the top of the spiral blade 42, and an end chamber 433 located above the spray port 431. A driving mechanism 50 connected to the top of the spiral blade 42 is arranged in the top chamber 432. A channel for discharging powder is provided on the side of the spray port 431 close to the feeding mechanism 20; The driving mechanism 50 includes a first rotating rod 51 rotatably arranged in the top chamber 432 and penetrating into the injection port 431, and a second rotating rod 54 rotatably arranged in the end chamber 433. The end of the first rotating rod 51 is connected to the top of the spiral blade 42 and a driving wheel 52 is sleeved on the surface. The surface of the second rotating rod 54 is sleeved with a driven wheel 55. The driving wheel 52 and the driven wheel 55 are directly sleeved with a transmission belt 53. A hole for the transmission belt 53 to pass through is opened at the connection between the top chamber 432 and the end chamber 433. A transmission rod 58 is also rotatably disposed in the end chamber 433 and is vertically distributed with the second rotating rod 54. The second rotating rod 54 and the transmission rod 58 are respectively sleeved with a first bevel gear 56 and a second bevel gear 57 that mesh with each other. With this design, the spiral blade 42 rotates to deliver the powder to the spray port 431 for scattering, and can also cooperate with the first rotating rod 51 to drive the driving wheel 52 to rotate. The torque generated by the driving wheel 52 is transmitted to the driven wheel 55 through the transmission belt 53, so that the driven wheel 55 drives the first bevel gear 56 to rotate through the second rotating rod 54. Under the meshing cooperation of the first bevel gear 56 and the second bevel gear 57, the torque is transmitted to the transmission rod 58, and the transmission rod 58 can rotate. At the same time, the transmission rod 58 is provided with an air supply mechanism 60. Fig. 9 and Fig.10 As shown, the air supply mechanism 60 includes a crankshaft 61 and a piston 64 installed in the top chamber 432, the transmission rod 58 is connected to the crankshaft 61 and a plurality of connecting rods 62 are connected to the crankshaft 61, a piston cavity 63 connected to the connecting rod 62 is provided in the piston 64, and an air supply nozzle 67 is installed at the end of the piston 64; When the transmission rod 58 rotates, it drives the crank shaft 61 to rotate, so that the crank shaft 61 can push the piston cavity 63 to move inside the piston 64 through the connecting rod 62. In order to avoid inhaling dust, an air inlet is provided on the outer wall of the piston 64, and an air supply device 65 is provided in the top chamber 432, and the air supply device 65 is connected to the air inlet of the piston 64. As the connecting rod 62 pulls the piston cavity 63, air is sucked into the piston 64 through the air supply device 65. When the connecting rod 62 pushes the piston cavity 63, the air passes through the piston 64 to the air supply nozzle 67 and is ejected. During the ejection process, the air flow velocity increases to form a stronger jet. After contacting the powder thrown from the injection port 431, it helps to blow the powder away and distribute it more evenly in the powder placement cavity 31, thereby achieving the purpose of improving the uniformity of powder coating.

[0023] Further, such as Fig. 9 As shown, the air supply nozzle 67 is arranged to be inclined and to penetrate a channel opened on the surface of the injection port 431. The air outlet path of the air supply nozzle 67 intersects with the parabolic trajectory of the powder when it is discharged from the injection port 431. Through this design, a force is exerted on the powder when the airflow meets the powder, thereby changing its original parabolic trajectory, which helps to distribute the powder in a wider area and disperse the powder particles to avoid local accumulation, thereby achieving more uniform scattering.

[0024] At the same time, a one-way valve 66 is provided at the end of the piston 64, which can only be rotated to open toward the air supply nozzle 67. The inner wall of the piston 64 is provided with a channel that abuts against the closed one-way valve 66. Through this design, when the connecting rod 62 pulls the piston cavity 63 to suck air into the piston 64 through the air supply device 65, the one-way valve 66 can rotate and abut to block the channel, thereby preventing the air supply nozzle 67 from sucking powder into the piston 64 while closing the piston 64, thereby improving the air supply effect of the air supply device 65.

[0025] The present invention also provides a multi-strain flavored fermented bean curd coupled preparation process, which is applied to the multi-strain flavored fermented bean curd coupled preparation device, and the specific use steps are as follows: S1. Place the upper net bag 21 in the assembly frame 23, insert the first insertion rod 71 into the limiting groove 231, and rotate the block 74 in the first insertion rod 71 in cooperation with the positioning rail 73. After placing the fermented bean curd in the lower net bag 22, place the lower net bag 22 in the assembly frame 23. The upper net bag 21 and the lower net bag 22 are connected and assembled into a complete circle through the block 74 and cannot be separated. The fermented bean curd is placed. S2. After rotating the top cover 13 to close it, start the electric telescopic rod 131, so that the electric telescopic rod 131 drives the upper net bag 21 and the lower net bag 22 to drop to the processing position through the combination rod 24 and the combination frame 23; S3. Start the power source 11, so that the gear 46 meshes with the gear ring 47 and rotates as the powder placement chamber 31 rotates. At this time, the gear 46 cooperates with the spiral blade base 44 and the mounting seat 45 to drive the spiral blade 42 to rotate inside the straight cylinder 41. The powder in the powder placement chamber 31 enters the straight cylinder 41 through the opening at the bottom of the straight cylinder 41, and rises to the sleeve 43 driven by the spiral blade 42, and is thrown from above the upper net bag 21 and the lower net bag 22; S4. While scattering, the spiral blade 42 drives the transmission rod 58 to rotate, and when the transmission rod 58 rotates, the crank shaft 61 is driven to rotate, so that the crank shaft 61 can push the piston chamber 63 to move inside the piston 64 through the connecting rod 62. When the connecting rod 62 pushes the piston chamber 63, the air passes through the piston 64 to reach the air supply nozzle 67 and is ejected. During the ejection process, the air flow speed increases to form a strong jet, which helps to blow the powder away and distribute it more evenly in the powder placement chamber 31 after contacting the powder thrown from the injection port 431; S5.
