Description

Technical Field

[0001] The present invention relates to the technical field of tofu preparation equipment, and particularly to a steaming device for producing boxed tofu. Background Art

[0002] Tofu is a traditional food originating from China with a history of thousands of years. It is made from soybeans through multiple steps such as soaking, grinding, boiling, filtering, and coagulating. Tofu is not only a protein source for vegetarians but also one of the widely consumed foods around the world, especially in Asia. The following details the production process, types, nutritional value, eating methods, and cultural significance of tofu.

[0003] Currently, boxed tofu is a prefabricated tofu product produced through packaging and storage technologies, usually used for home cooking and convenient food options. Boxed tofu has multiple advantages, such as convenient storage, easy to carry, and maintaining freshness for a long time. During the tofu production process, steaming is an essential step. During steaming, the generation of foam is inevitable, and it is necessary to manually remove the foam regularly with a spoon or a strainer, which can not only make the soy milk clearer but also prevent the foam from affecting the texture and taste of the tofu. However, when steaming soy milk, the temperature is relatively high, and the hands are easily injured by the steam, and it is not suitable for large-scale production scenarios. Therefore, there is an urgent need for a device that can automatically remove foam.

[0004] Chinese Patent CN116530716B discloses a full-automatic tofu making machine, including a soy milk boiling barrel. The upper end of the soy milk boiling barrel is slidably connected with a cover. The middle part of the upper end of the cover is provided with a transmission mechanism. The lower part of the transmission mechanism is provided with an aggregate for collecting floating foam. The upper part of the rotating rod is provided with a scraper for scraping the floating foam. One side of the aggregate away from the rotating rod is provided with a guiding member for adjusting the position of the scraper. When the scraper and the aggregate approach each other, the front end of the guiding member cooperates with the scraper, so that the scraper changes from a vertical state to a horizontal state. When the scraper and the aggregate move away from each other, the end of the guiding member cooperates with the scraper, and the scraper changes from a horizontal state to a vertical state. The invention scrapes the floating foam on the surface of the soy milk liquid in two opposite rotating directions, quickly scrapes the surface floating foam, and the scraper cooperating with the guiding member can change the position state of the scraper when the shell contacts the scraper.

[0005] The above patent collects the floating foam through scrapers in opposite directions and then discharges it outside the device through a straw. However, its structure is relatively closed, inconvenient to view, and the closed environment is likely to cause an increase in soy milk floating foam, resulting in overflow, and its practical value is not high. Therefore, it is necessary to develop a visible and automatic foam-removing steaming device for producing tofu. Summary of the Invention

[0016] Preferably, a valve is provided at the discharge port.

[0017] The present invention also claims to protect a use method of a steaming device for producing boxed tofu, including the following steps:

[0018] S1: Pour the soy milk into the pot body from the pot mouth, and control the heating coil to heat the soy milk;

[0019] S2: When heating, drive the second motor to drive the stirring shaft to rotate and stir the soymilk in the pot body; drive the lifting rod, and through the downward movement of the lifting rod, drive the rotating shaft to move downward. After adjusting the defoaming net bag to the floating foam above the soymilk liquid, drive the first motor to rotate. During the rotation, the defoaming net bag rotates 30 - 150° in the pot body. After catching the floating foam, stop the rotation of the first motor; meanwhile, during the downward movement of the rotating shaft, the second support plate in the airbag drives the telescopic rod to extend under its own gravity, increasing the pressure inside the airbag. Under the internal and external pressure difference, the second one-way valve is forced to open, and gas is input into the airbag. After the airbag is inflated and the pressure is balanced, the second one-way valve automatically closes;

[0020] S3: After catching the floating foam, drive the lifting rod to rise. While rising, drive the rotating shaft to rise, and drive the floating foam caught in the defoaming net bag above the pot body. Continue to drive the first motor to rotate. When it rotates to the foam collecting tank, the baffle on the foam collecting tank blocks the L-shaped flexible net bag. At this time, the rotating shaft continues to rotate, and the baffle is squeezed. When the L-shaped flexible net bag crosses the baffle, the instantaneous elastic force formed ejects the floating foam out of the L-shaped flexible net bag into the tank body to complete the collection of the floating foam. At this time, the defoaming net bag rotates one circle and stops rotating at the initial descending position, and the baffle returns to its original position under the elastic force of the first spring; meanwhile, during the upward movement of the rotating shaft, the limiting disc squeezes the bottom of the airbag, and the second support plate inside the airbag rises to compress the internal telescopic rod. During the compression, the pressure inside the airbag increases, squeezing the first one-way valve, forcing the first one-way valve to open, so that the gas inside the airbag enters the blowing nozzle through the air outlet pipe and is ejected. The blowing nozzle blows the floating foam on one side close to the foam collecting tank to the other side, facilitating the defoaming of the defoaming net bag;

[0021] S4: After the soymilk boils, reduce the heating temperature of the heating coil, and repeat S2 - S3 for 8 - 15 minutes of steaming;

[0022] S4: After the soymilk steaming is completed, stop the floating foam collection, add a coagulant to the soymilk, continue to stir, and after stirring evenly, discharge it from the discharge port and load it into the box body for coagulation.

[0023] Preferably, in S2, drive the lifting rod, and through the downward movement of the lifting rod, drive the rotating shaft to move downward, and adjust the defoaming net bag to the floating foam above the soymilk liquid. The specific process is as follows:

[0024] The initial position of the second net bag extends out of the edge of the pot body. When the defoaming net bag descends, the second net bag rotates upward along the rotating column, and the L-shaped flexible net bag at the connection between the first net bag and the second net bag is bent, and the end of the second net bag away from the first net bag abuts against the inner wall of the pot body; when the defoaming net bag descends to the floating foam above the soy milk liquid, the rotating shaft rotates, and under the rotation of the rotating shaft, the second net bag gradually becomes parallel to the bottom plate of the first net bag, and the floating foam on the edge of the inner wall of the pot body is collected into the second net bag. Under the continued rotation of the rotating shaft, the second net bag is gradually squeezed. During the squeezing process, the second net bag is pushed to continue to rotate upward along the rotating column. The second net bag rotates upward to form an angle with the first net bag, completing the angular rotation of the rotating shaft;

[0025] In S3, the lifting rod is driven to rise, and at the same time, the rotating shaft is driven to rise, so that the floating foam caught in the foam removal net bag is driven to the top of the pot body. The specific steps are:

[0026] The second net bag that rotates upward slides upward along the inner wall of the pot body during the rising process of the rotating shaft. When it slides to the top of the pot body, the elastic force of the torsion spring makes the second net bag be horizontally set, parallel to the bottom plate of the first net bag, and the end of the second net bag away from the foam collecting groove is located outside the pot body.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The defoaming assembly provided in the present invention realizes the function of the defoaming net bag to take out the floating foam through the descent and rotation of the rotating shaft, and inflates the air bag at the same time; the floating foam on the defoaming net bag is poured into the foam collecting tank through the ascent and rotation of the rotating shaft, which is convenient for the defoaming net bag to descend and take out the floating foam for the next round. At the same time, during the ascent of the rotating shaft, the air bag is squeezed, so that the gas inside the air bag is discharged through the blowing nozzle, and the floating foam near one end of the foam collecting tank is blown to the other side, which is convenient for the defoaming net bag to remove the foam. At the same time, the floating foam generated by the soy milk in the entire pot can be removed, thereby removing the bean smell and having a good cleaning effect. In addition, the removal of the floating foam is visualized throughout the process, avoiding the technical problem that the closed environment causes an increase in soy milk floating foam, resulting in soy milk overflow and affecting the production effect, thereby ensuring the quality of the soy milk and the taste of the final tofu.

[0029] (2) The second net bag of the present invention is hingedly connected to the first net bag, so that the second net bag can rotate upward along the rotating column, which is convenient for the second net bag to descend. After the second net bag descends, it can be straightened to collect the floating foam on the edge of the pot body, thereby solving the problem that the floating foam on the edge of the pot body cannot be cleaned due to the eccentric setting of the rotating shaft, increasing the defoaming area of ​​the defoaming net bag and achieving a good defoaming effect.

Detailed implementation manners

[0038] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not used to limit the present invention. And without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0039] Embodiment 1

[0040] AsFigures 1 to 7 As shown in the figure, a steaming device for producing boxed tofu includes a pot body 100. An outlet 150 is provided on the lower side wall of the pot body 100. A heating coil 700 is installed at the bottom of the pot body 100. A support column 110 is fixed on one side of the pot body 100. A first fixing plate 120 is fixed on the top of the pot body 100 through the support column 110. A defoaming component 300 is installed on the first fixing plate 120. A stirring component 400 is also installed at the lower end of the pot body 100. A foam collecting tank 500 is detachably installed outside the top of the pot body 100. The foam collecting tank 500 is arranged on one side close to the stirring component 400.

[0041] The outlet 150 is used to discharge the cooked soy milk into the box body of the next process for coagulation. The heating coil 700 is used to heat the soy milk contained in the pot body to complete the steaming of the soy milk. The first fixing plate 120 is used to support the defoaming component 300, and the first fixing plate 120 is installed on the top of the pot body 100, so that the steaming state of the internal soy milk is visible. The stirring component 400 is used to stir the soy milk. Stirring can prevent the soy milk from depositing at the bottom of the pot and forming a paste, resulting in burning. The foam collecting tank 500 is used to collect the fished-up foam.

[0042] The defoaming component 300 includes a lifting rod 310 fixed on the top of the first fixing plate 120. The top of the lifting rod 310 is fixed with a second fixing plate 130. A first motor 320 is fixedly installed on the top of the second fixing plate 130. A rotating shaft 330 is rotatably connected to the second fixing plate 130. The rotating shaft 330 is eccentrically arranged along the pot body 100. The output shaft of the first motor 320 is fixedly connected to the top of the rotating shaft 330. The lower end of the rotating shaft 330 passes through the first fixing plate 120 and a defoaming net bag 600 is fixed at the bottom. A limiting disk 321 is also fixed on the rotating shaft 330 above the defoaming net bag 600. A blowing component 350 is abutted on the limiting disk 321. The blowing component 350 is vertically fixed below the first fixing plate 120.

[0043] The lifting rod 310 is used to control the lifting of the defoaming net bag 600, and the rotating shaft 330 is used to control the rotation of the defoaming net bag 600. When defoaming, it is necessary to first lower the defoaming net bag 600 to the height of the foam above the soy milk, rotate a certain angle to collect the foam, and then raise the defoaming net bag 600 after collection to collect the collected foam into the foam collecting tank 500, and cycle in turn to achieve the effect of removing foam.

[0044] It should be noted that the rotating shaft 330 rotates one circle to complete one defoaming. The specific rotation angle of the defoaming net bag in the pot body 100 can be adjusted according to actual needs and is not limited here.

[0045] In this embodiment, the blowing component 350 includes an airbag 351. A first support plate 352 is fixed to the inner top of the airbag 351, and a second support plate 353 is fixed to the inner bottom of the airbag 351. A telescopic rod 354 is connected between the first support plate 352 and the second support plate 353. The top of the airbag 351 and the first support plate 352 are fixed to the lower end of the first fixing plate 120. The airbag 351 is communicated with an air outlet pipe 355. The intake end of the air outlet pipe 355 is communicated with the airbag 351, and the outlet end of the air outlet pipe 355 is connected with a blowing nozzle 356. The nozzle of the blowing nozzle 356 faces downward, and the blowing nozzle 356 is located on the inner wall of the pot body 100 close to one side of the foam collecting tank 500. A first one-way valve 357 is installed on the air outlet pipe 355, and a second one-way valve 358 is installed on the airbag 351.

[0046] The air outlet pipe 355 is a rigid pipe. When the lifting rod 310 descends, the airbag 351 generates air pressure under the action of the gravity of the second support plate 353. Under the action of the pressure difference inside and outside the airbag 351, the second one-way valve 358 is opened to inflate the airbag 351, and it automatically closes after inflation. When the lifting rod 310 ascends, the limit disk 321 ascends to squeeze the airbag 351. During the squeezing process, the gas blown out by the blowing nozzle 356 blows the floating foam that cannot be touched by the foam removing net bag 600 to the other end, which is convenient for the foam removing net bag 600 to collect. The function of blowing the floating foam while removing the foam is realized, which ensures the foam removing effect and makes the prepared tofu have a better taste.

[0047] In this embodiment, the foam removing net bag 600 includes a connecting rod 610 fixedly connected to the rotating shaft 330. One end of the connecting rod 610 far from the rotating shaft 330 is axially connected with a first net bag 620. The first net bag 620 is provided with a first bottom plate 621, and there are a plurality of water filtering holes on the first bottom plate 621. An installation ring 622 is provided at one end of the first bottom plate 621 far from the rotating shaft 330. The installation ring 622 is connected with a second net bag 630 through a rotating column 631. The second bottom plate 632 of the second net bag 630 is flush with the bottom of the first bottom plate 621, and there are a plurality of water filtering holes on the second bottom plate 632. A torsion spring 640 is sleeved in the middle of the rotating column 631. One limiting end side of the torsion spring 640 abuts above the first bottom plate 621, and the other side abuts above the second bottom plate 632. An L-shaped flexible net bag 650 is commonly connected to the first bottom plate 621 and the second bottom plate 632.

[0048] The foam removing net bag 600 is used to remove the floating foam. Specifically, the opening direction of the L-shaped flexible net bag 650 is the direction of foaming collection, and the opening direction is not limited here. The rotation direction is determined according to the opening direction. The second net bag 630 hinged to the first net bag 620 can clean the floating foam at the edge of the pot body, achieving a better foam removing effect.

[0049] In this embodiment, the foam collecting trough 500 includes a trough body 510. One end of the trough body 510 connected to the pot body 100 is arc-shaped. The trough body 510 is detachably mounted on the pot body 100 through a mounting member 520, and the top of the trough body 510 is flush with the top of the pot body 100. A baffle 530 is vertically rotatably connected to the top of the end of the trough body 510 away from the pot body 100, and a first spring 540 is hinged between one side of the baffle 530 and the inner wall of the trough body 510.

[0050] The trough body 510 is used for collecting foam. The mounting member 520 is used for fixing the trough body 510 on the outer side wall of the pot body 100. After the foam collection is completed, it can be removed for cleaning. The baffle 530 is used to block the tip of the defoaming net bag 600, and the baffle 530 is arranged on the movement track of the defoaming net bag 600. The first spring 540 is used for resetting the baffle 530. Specifically, during defoaming, the end of the second net bag 630 of the rotating defoaming net bag is blocked by the baffle 530. With the continuous rotation of the rotating shaft, due to the material setting of the defoaming net bag 600, it can be bent to a certain extent. When the defoaming net bag 600 passes over the baffle 530, its elastic force throws the foam in the net bag into the trough body 510 of the foam collecting trough 500, completing the cleaning of the foam in the defoaming net bag 600, facilitating the next foam scooping, and having a good cleaning effect.

[0051] In this embodiment, the stirring assembly 400 includes a stirring shaft 410 horizontally rotatably connected in the pot body 100. One end of the stirring shaft 410 extends out of the pot body 100 through the side wall of the pot body 100. An installation seat 420 is further provided on the lower side wall of the pot body 100. A second motor 430 is installed on the installation seat 420, and the output shaft of the second motor 430 is fixedly connected to one end of the stirring shaft 410 extending out of the pot body 100. A plurality of stirring blades 440 are installed on the stirring shaft 410 located in the pot body 100.

[0052] In this embodiment, the telescopic rod 354 includes a plurality of sequentially and continuously sleeved rods 3541.

[0053] In this embodiment, the first net bag 620 and the second net bag 630 are made of silica gel.

[0054] In this embodiment, a valve is provided on the discharge port 150.

[0055] Embodiment 2

[0056] A method for using a steaming device for producing boxed tofu, comprising the following steps:

[0057] S1: Pour the soymilk into the pot body 100 from the pot mouth, and control the heating coil 700 to heat the soymilk;

[0058] S2: During heating, drive the second motor 430 to drive the stirring shaft 410 to rotate to stir the soymilk in the pot body 100; drive the lifting rod 310. As the lifting rod 310 descends, drive the rotating shaft 330 to descend. After adjusting the defoaming net bag 600 to the floating foam above the soymilk liquid, drive the first motor 320 to rotate. During rotation, the defoaming net bag 600 rotates 30-150° in the pot body 100. After catching the floating foam, stop the rotation of the first motor 320; at the same time, during the downward movement of the rotating shaft 330, the second support plate 353 in the airbag 351 drives the telescopic rod 354 to extend under its own gravity, increasing the pressure in the airbag 351. Under the internal and external pressure difference, the second one-way valve 358 is forced to open, and gas is input into the airbag 351. After the airbag 351 is inflated, the pressure is balanced and the second one-way valve 358 automatically closes;

[0059] S3: After catching the floating foam, drive the lifting rod 310 to rise. While rising, drive the rotating shaft 330 to rise, driving the floating foam caught in the defoaming net bag 600 above the pot body 100. Continue to drive the first motor 320 to rotate. When it rotates to the foam collecting groove 500, the baffle 530 on the foam collecting groove 500 blocks the L-shaped flexible net bag 650. At this time, the rotating shaft 330 continues to rotate, and the baffle 530 is squeezed. When the L-shaped flexible net bag 650 crosses the baffle, the instantaneous elastic force formed ejects the floating foam out of the L-shaped flexible net bag 650 into the trough body 510, completing the collection of the floating foam. At this time, the defoaming net bag 600 rotates one circle and stops rotating at the initial descending position, and the baffle 530 returns to its original position under the elastic force of the first spring 540; at the same time, during the upward movement of the rotating shaft 330, the limit disc 321 squeezes the bottom of the airbag 351, and the second support plate 353 inside the airbag 351 rises to compress the internal telescopic rod 354. During compression, the pressure inside the airbag 351 increases, squeezing the first one-way valve 357, forcing the first one-way valve 357 to open, so that the gas inside the airbag 351 enters the air blowing nozzle 356 through the air outlet pipe 355 and is ejected. The air blowing nozzle 356 blows the floating foam on the side close to the foam collecting groove 500 to the other side, facilitating the defoaming net bag 600 to remove the foam;

[0060] S4: After the soymilk boils, reduce the heating temperature of the heating coil 700, and repeat S2-S3 for 8-15 minutes;

[0061] After the soy milk is boiled, it is necessary to adjust the heating temperature of the heating coil 700 to avoid serious foaming or even overflow of the soy milk caused by continuous high heat. Specifically, the heating temperature adjustment is made according to the actual situation and is not limited again. The temperature control of the heating temperature of the heating coil 700 can be controlled by a controller. The controller can be a PLC controller and can control the lifting rod 310, the first motor 320, and the second motor 430. In addition, a temperature sensor can be set on the pot body 100 to monitor the temperature of the soy milk, which is convenient for better adjusting the temperature, and the taste of the prepared tofu will be better.

[0062] S4: After the soy milk steaming is completed, stop collecting the foam. Add a coagulant to the soy milk and continue stirring. After stirring evenly, discharge it from the discharge port 150 and put it into a box for solidification.

[0063] In this embodiment, in S2, drive the lifting rod 310. By the downward movement of the lifting rod 310, drive the rotating shaft 330 to move downward, and adjust the defoaming net bag 600 to the foam above the soy milk liquid. The specific process is as follows:

[0064] The initial position of the second net bag 630 extends beyond the edge of the pot body 100. When the defoaming net bag 600 descends, the second net bag 630 rotates upward along the rotating column 631. The L-shaped flexible net bag 650 at the connection between the first net bag 620 and the second net bag 630 is bent. One end of the second net bag 630 away from the first net bag 620 abuts against the inner wall of the pot body 100; when the defoaming net bag 600 descends to the foam above the soy milk liquid, the rotating shaft 330 rotates. Under the rotation of the rotating shaft, the second net bag 630 gradually becomes parallel to the bottom plate of the first net bag 620, and the foam at the edge of the inner wall of the pot body 100 is collected into the second net bag 630. Under the continuous rotation of the rotating shaft 330, the second net bag 630 is gradually squeezed. During the squeezing process, the second net bag 630 is pushed to continue rotating upward along the rotating column 631. The second net bag 630 rotates upward and forms an angle with the first net bag 620, completing the angular rotation of the rotating shaft 330;

[0065] In S3, drive the lifting rod 310 to rise. While rising, drive the rotating shaft 330 to rise, and drive the foam caught in the defoaming net bag 600 above the pot body 100. The specific steps are as follows:

[0066] The upward-rotating second net bag 630 slides upward along the inner wall of the pot body 100 during the rising process of the rotating shaft 330. When it slides to the top of the pot body 100, the elastic force of the torsion spring 640 makes the second net bag 630 horizontally arranged and parallel to the bottom plate of the first net bag 620. One end of the second net bag 630 away from the foam collecting groove 500 is located outside the pot body 100.

[0067] Although the present invention has been disclosed above by way of examples, it is not intended to limit the present invention. Any person skilled in the relevant art can make some changes or modifications within the scope of the technical solution of the present invention to obtain equivalent embodiments with equivalent changes. However, as long as it does not depart from the technical solution of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.

9. A method for using the steaming and boiling device for producing boxed tofu according to any one of claims 1 to 8, characterized in that: The steps include: S1: pouring soy milk from the pot mouth into the pot body (100), and controlling the heating coil (700) to heat the soy milk; S2: During heating, the second motor (430) is driven to drive the stirring shaft (410) to rotate and stir the soybean milk in the pot body (100); the lifting rod (310) is driven to lower the lifting rod (310) to drive the rotating shaft (330) downward, and after the defoaming net bag (600) is adjusted to the floating foam above the soybean milk liquid, the first motor (320) is driven to rotate. During the rotation, the defoaming net bag (600) rotates 30 to 150 degrees in the pot body (100) to hold the floating foam. , the first motor (320) is stopped from rotating; at the same time, during the downward movement of the rotating shaft (330), the second support plate (353) in the airbag (351) drives the telescopic rod (354) to extend under its own weight, so that the pressure in the airbag (351) increases. Under the pressure difference between the inside and the outside, the second one-way valve (358) is passively opened, and gas is input into the airbag (351). After the airbag (351) is inflated, the pressure is balanced and the second one-way valve (358) is automatically closed; S3: After the floating foam is collected, the lifting rod (310) is driven to rise, and while rising, the rotating shaft (330) is driven to rise, so that the floating foam collected in the foam removal net bag (600) is driven to the top of the pot body (100), and the first motor (320) is driven to rotate. When the floating foam is collected in the foam collecting groove (500), the baffle (530) on the foam collecting groove (500) blocks the L-shaped flexible net bag (650). At this time, the rotating shaft (330) continues to rotate, and the baffle (530) is squeezed. When the L-shaped flexible net bag (650) passes over the baffle, the instantaneous elastic force formed ejects the floating foam from the L-shaped flexible net bag (650) into the groove body (510), and the collection of the floating foam is completed. At this time, the foam removal net bag (600) rotates one circle and is at the initial descending position. The rotation of the airbag (351) is stopped at the position where the airbag (351) is placed, and the baffle (530) returns to its original position under the elastic force of the first spring (540); at the same time, when the rotating shaft (330) rises, the limiting plate (321) squeezes the bottom of the airbag (351), and the second supporting plate (353) inside the airbag (351) rises to compress the internal telescopic rod (354). During compression, the pressure inside the airbag (351) increases, squeezing the first one-way valve (357), forcing the first one-way valve (357) to open, so that the gas inside the airbag (351) enters the air blowing nozzle (356) through the air outlet pipe (355) and is ejected. The air blowing nozzle (356) ejects the floating foam near one side of the foam collecting groove (500) to the other side, so that the foam removal net bag (600) can remove foam. S4: After the soy milk boils, lower the heating temperature of the heating coil (700), repeat S2 to S3, and cook for 8 to 15 minutes; S4: After the soy milk is cooked, the collection of the floating foam is stopped, and a coagulant is added to the soy milk, and the soy milk is stirred continuously.

The specific process is as follows: The initial position of the second net bag (630) extends out of the edge of the pot body (100). When the defoaming net bag (600) descends, the second net bag (630) rotates upward along the rotating column (631), and the L-shaped flexible net bag (650) at the connection between the first net bag (620) and the second net bag (630) is bent, and the end of the second net bag (630) away from the first net bag (620) abuts against the inner wall of the pot body (100); when the defoaming net bag (600) descends to the floating foam above the soy milk liquid, the rotating shaft (330) is rotated. Rotate, under the rotation of the rotating shaft, the second net bag (630) gradually becomes parallel to the bottom plate of the first net bag (620), and collects the foam on the edge of the inner wall of the pot body (100) into the second net bag (630), and under the continuous rotation of the rotating shaft (330), the second net bag (630) is gradually squeezed, and during the squeezing process, the second net bag (630) is pushed to continue to rotate upward along the rotating column (631), and the second net bag (630) rotates upward to form an angle with the first net bag (620), thereby completing the angular rotation of the rotating shaft (330); In S3, the lifting rod (310) is driven to rise, and while rising, the rotating shaft (330) is driven to rise, so that the floating foam caught in the foam removal net bag (600) is driven to the top of the pot body (100). The specific steps are as follows: The second net bag (630) that rotates upward slides upward along the inner wall of the pot body (100) during the rising process of the rotating shaft (330). When sliding to the top of the pot body (100), the elastic force of the torsion spring (640) causes the second net bag (630) to be arranged horizontally, parallel to the bottom plate of the first net bag (620), and the end of the second net bag (630) away from the foam collecting groove (500) is located outside the pot body (100).
