Description

Technical Field

[0001] The invention relates to soft tofu slurrying equipment and a processing method thereof, belonging to the technical field of tofu processing. Background Art

[0002] Soft tofu, also known as gypsum tofu, is made with liquid gypsum. Compared to northern tofu, it has a softer, more delicate texture. Gypsum-based tofu is quite common in rural areas. The basic process is the same as for making brine, sour water, or "sweet tree leaf" tofu, except that gypsum is used instead of brine, sour water, and sweet tree leaf juice. Gypsum tofu is white in color, has a delicate, soft texture, is rich in protein, and is highly nutritious.

[0003] The production process of tender tofu is as follows: soybeans → soaking → grinding → filtering → boiling → slurrying → wrapping → finished product. The slurrying step is very critical. The existing technology generally adopts the following two methods for slurrying: first, manually adding gypsum coagulant. Manual addition of gypsum coagulant has the problem of inconsistency between the amount of coagulant and the time of adding coagulant, which will cause inconsistent quality of the finished product and difficult to control the quality; second, relying on controlling the opening time of the pneumatic valve to control the amount of gypsum coagulant added; this method uses the pneumatic valve opening time to add coagulant, which can keep the coagulant addition time consistent. The gypsum coagulant and soy milk need to be fully mixed to make the whole plate of tofu tender.

[0004] The existing method of slurrying soft tofu requires an additional stirring bucket to fully mix the gypsum coagulant and soy milk after they are proportioned, and then they are further placed in the slurrying frame. Since the mixed liquid is fully mixed in the process of stirring, in order to reduce bubbles as much as possible, the stirring time cannot be too fast. Therefore, the mixing process takes a while, resulting in the output efficiency being restricted and the processing efficiency being difficult to improve.

[0005] Therefore, the research purpose of the present invention is to design a mixing device that can replace the original mixing device used for stirring, and to form a vortex in the mixing container by utilizing the impact kinetic energy of the soy milk when it impacts, so as to achieve self-mixing with high efficiency. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a soft tofu slurrying equipment and a processing method thereof, so as to solve the problem that the soft tofu slurrying and loading method of the existing technology requires an additional stirring bucket to fully mix the gypsum coagulant and soy milk after they are proportioned, and then they are further placed in the slurrying frame. Since the process of stirring the mixed liquid for full mixing takes a period of time, and the gypsum coagulant and soy milk will gradually begin to solidify after mixing, although the stirring mixing enhances the mixing degree of the gypsum coagulant and soy milk, it will also cause more dense bubbles in the soy milk, thereby affecting the molding quality of the soft tofu.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] A soft tofu slurrying device includes a frame and a plurality of raw material containers fixed on the frame, wherein each raw material container is provided with a discharge pipe with a corresponding solenoid valve downwardly, the raw material container includes a soy milk bucket and an additive cylinder, and the discharge device also includes a tumbling discharge mechanism, which includes:

[0009] A material mixing container is installed on the frame in a transversely movable manner, wherein a material mixing chamber is provided in the material mixing container, the opening of which faces the discharge pipe;

[0010] A material box fixing frame is movably mounted on the frame, wherein a corresponding material box is installed in the material box fixing frame, and a feeding end of the material box is arranged at the lower side of the opening of the material mixing container. When the material box fixing frame moves downward, the opening of the material mixing container is turned downward and faces the feeding end of the material box;

[0011] A blocking mechanism is provided above the material box fixing frame and is used to block the material box;

[0012] The discharging conveyor belt is arranged on the frame at the lower side of the material box fixing frame, and is used for discharging the material box loaded with materials.

[0013] As a further improvement, the bottom of the material mixing chamber and the rear side surface away from the opening end are both configured to be outwardly convex arc surfaces.

[0014] As a further improvement, the material box fixing frame is driven by a corresponding driving cylinder, a cross bar is fixedly installed in the middle of the material box fixing frame, the driving cylinder is fixedly installed on the frame, a stabilizing frame is fixedly installed at the output end of the driving cylinder, and the lower end of the stabilizing frame is fixedly connected to the cross bar in the middle of the material box fixing frame.

[0015] As a further improvement, the material mixing container includes an upper cover and a lower cover fixed under the upper cover, and a movable wheel is rotatably installed under the lower cover. The movable wheel is arranged under the lower cover away from the opening end of the material mixing container, and the movable wheel is rollingly arranged on the frame.

[0016] As a further improvement, the output end of the driving cylinder faces upward.

[0017] As a further improvement, the stabilizing frame includes a support plate welded to the frame and a connecting plate located directly above the support plate. The driving cylinder is fixed above the support plate, and the output end of the driving cylinder is fixed to the middle of the connecting plate. Two lifting rods are vertically installed under the connecting plate. The lifting rods pass through the support plate and are welded to the middle cross bar of the material box fixing frame.

[0018] As a further improvement, a pipe sleeve is sleeved on the outside of the lifting rod, and the top of the pipe sleeve is fixedly installed under the support plate.

[0019] As a further improvement, one side of the material box fixing frame is provided with an unobstructed opening for the material box to slide into, and a connecting piece is provided on the side corresponding to the unobstructed opening of the material box fixing frame, and the connecting piece is rotatably mounted on the lower end of the opening of the material mixing container.

[0020] As a further improvement, the invention further comprises a control box fixed on the frame, wherein the control box is electrically connected to the driving cylinder and the solenoid valve on the discharge pipe.

[0021] The beneficial effects of the present invention are:

[0022] The present invention forms a material mixing container without a stirring piece by combining a semi-open upper cover and an arc-shaped lower cover in the material mixing container, which replaces the existing stirring and mixing method. It can enhance the mixing degree of the gypsum coagulant and the soy milk while preventing excessive bubbles from being formed in the soy milk. It can also reduce the fine pores inside the soft tofu after it is formed, thereby increasing its tenderness and smoothness.

[0023] To ensure the mixing effect, the bottom of the material mixing chamber in the material mixing container and the rear side surface away from the opening end are set to be an outward-convex arc surface, so that the soy milk with impact potential energy entering through the opening of the material mixing chamber can automatically roll over through the arc surface inner cavity, further mixing the gypsum liquid, thereby enhancing the mixing effect.

[0024] In order to enhance the mixing effect, a connecting piece is provided on the side corresponding to the material box fixing frame and the unobstructed opening. The connecting piece is rotatably installed at the lower end of the opening of the material mixing container. When the material box fixing frame moves downward, the open end of the material mixing container is pulled downward, and the opening is flipped downward and faces the feed end of the material box, and then the mixed material is poured into the material box, and the mixing is further completed with the help of the flipping kinetic energy.

[0025] In order to stably control the downward movement of the material box fixing frame, a driving cylinder is set, and the driving cylinder controls the lifting and lowering of the material box fixing frame through the stabilizing frame.

[0026] By setting up a material mixing container and completing the initial mixing with the help of the impact kinetic energy of the soy milk, the mixing operation is performed again during the pouring process. It can complete sufficient mixing without the cooperation of a stirring rod, and the single mixing time is short. It is immediately output to the slurry frame after the mixing is completed. By adopting the self-mixing method of the material mixing container to replace the stirring barrel, and configuring the material frame to immediately undertake the transfer of the mixed liquid after the mixing is completed, and automatically mix without stirring, achieving rapid mixing, it can also be mixed again during the transfer of the mixed liquid, fully ensuring the mixing degree of the gypsum coagulant and the soy milk while greatly shortening the mixing time, thereby reducing the constraints on the output efficiency and improving the processing efficiency.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] Reference Figure 1-5 7-11, a soft tofu slurrying device comprises: a frame 1, and a plurality of raw material containers 2 fixed on the frame 1, each of the raw material containers 2 is provided with a discharge pipe with a corresponding solenoid valve downwardly, and the discharge device further comprises a tumbling discharge mechanism 3, and the tumbling discharge mechanism 3 comprises:

[0042] The material mixing container 31 can be installed on the frame 1 in a transversely movable manner. The material mixing container 31 is provided with a material mixing chamber 311 whose opening faces the discharge pipe. A connecting ring 31a is provided on the outer side of the opening end of the material mixing container 31.

[0043] A material box fixing frame 32 is movably mounted on the frame 1. A corresponding material box 33 is mounted inside the material box fixing frame 32. The feeding end of the material box 33 is arranged below the opening of the material mixing container 31. When the material box fixing frame 32 moves downward, the opening of the material mixing container 31 turns downward and faces the feeding end of the material box 33.

[0044] A blocking mechanism is provided above the material box fixing frame 32 and is used to block the material box 33;

[0045] The discharging conveyor belt 7 is provided on the frame 1 below the material box fixing frame 32 and is used for discharging the material box 33 loaded with materials.

[0046] The above-mentioned existing stirring method usually adopts a stirring bucket. Although stirring and mixing strengthens the mixing degree of gypsum coagulant and soy milk, it also causes more bubbles in the soy milk, resulting in more fine pores inside the soft tofu after it is formed, affecting its tenderness. Figure 3 As shown, a material mixing container 31 is provided, and a material mixing container 31 without a stirring member is formed by combining a semi-open upper cover 312 and an arc-shaped lower cover 313 in the material mixing container 31.

[0047] In this embodiment, the raw material container 2 includes a soybean milk bucket 21 fixedly mounted on one side of the frame 1 and an additive cylinder 22 fixedly mounted on the other side of the frame 1 .

[0048] In addition, a first output tube 211 is fixedly installed below the soymilk barrel 21, and the first output tube 211 is provided with a double outlet sleeve 212, and the diameter of one outlet a1 of the double outlet sleeve 212 is equivalent to that of the first output tube 211, and the double outlet sleeve 212 and the corresponding outlet are installed with a first solenoid valve 213 for controlling the output state. In order to improve its output efficiency, the diameter is specifically 8-12 cm. When the diameter is less than 8 cm, it takes more time to output the same amount of soymilk, and when the diameter is greater than 12 cm, the space it occupies is larger and will squeeze the setting space of other output ports, and the soymilk liquid that rushes out instantly has a certain impact force. If the impact force exceeds 12 cm, it is too large and easily splashes out. Therefore, in this embodiment, it is further optimized to 10 cm.

[0049] The diameter of the other outlet a2 is 3-5 cm. When the diameter is less than 3 cm, it takes longer to discharge the same amount of soy milk. When the diameter is greater than 5 cm, the impact force is insufficient to fully stir the mixed liquid, making it difficult to generate sufficient swirling force, which affects the final mixing effect. Therefore, in this embodiment, the diameter is further optimized to 5 cm. A second solenoid valve 214 is installed at the corresponding outlet of the dual outlet sleeve 212 to control the output state. This soy milk is used to be discharged into the material mixing container 31.

[0050] In addition, a second output pipe 221 is fixedly installed under the additive cylinder 22, and a third solenoid valve 222 for controlling the output state is installed under the second output pipe 221, which is used to output additives to the material mixing container 31. In this embodiment, the additive is gypsum liquid used for tofu making.

[0051] In order to control the multiple solenoid valves and supply power thereto, an electric control box 4 is further installed inside the frame 1 . The electric control box 4 is electrically connected to the first solenoid valve 213 , the second solenoid valve 214 , and the third solenoid valve 222 .

[0052] During its use, first, by opening the first solenoid valve 213, soy milk is input into the material mixing container 31 through the first output pipe 211 to serve as a base. Thereafter, by opening the third solenoid valve 222, gypsum liquid is input into the material mixing container 31 to mix with the first batch of soy milk fixed in the material mixing container 31. Subsequently, the second solenoid valve 214 is opened to input soy milk toward the material mixing container 31. Since the input port is small, the impact force of the soy milk input for the second time is greater than that of the soy milk input for the first time. The impact force can impact the internal liquid and accelerate its mixing.

[0053] In order to enhance the tumbling mixing effect and prevent the tumbling mixed liquid from splashing out of the material mixing container 31 when the mixed liquid is impacted, the bottom of the material mixing chamber 311 and the rear side surface away from the opening end are both configured to be convex arc surfaces, so that the soy milk with impact potential energy entering through the opening of the material mixing chamber 311 can automatically roll up through the arc surface inner cavity and further mix with the gypsum liquid.

[0054] To further optimize the full utilization of the potential energy of the material mixing container 31, in this embodiment, the upper opening of the upper cover 312 of the material mixing container 31 is aligned with 5 / 9-2 / 3 of the horizontal length of the lower cover 313 from left to right. The upper cover 312 and the lower cover 313 are connected together by welding, and the internal welds are smoothed. If the alignment position of the upper opening of the upper cover 312 is less than 5 / 9 of the length, the length of the upper portion used to block the mixed liquid will be too short, and the mixed liquid in the swirling mixed state will easily splash out. If the length is greater than 2 / 3, the opening for feeding will be reduced, thereby affecting the placement of the pipeline for inputting liquid. Therefore, in this embodiment, the alignment is preferably aligned at 5 / 9 of the horizontal length of the lower cover 313 from left to right, which can save materials on the one hand and meet usage requirements on the other.

[0055] In addition, the inner side surfaces of the material mixing container 31 are polished and smooth, which can effectively prevent the inner layer from being adhered, and further, when the mixed liquid reacts and condenses, it is not easy to adhere to the inner side surface.

[0056] In order to make it smoother when the material mixing container 31 pours the mixed liquid into the material box 33, a movable wheel 314 is rotatably installed under the lower cover 313. The movable wheel 314 is arranged under the lower cover 313 away from the opening end of the material mixing container 31, and is designed to prevent the material mixing container 31 from pouring before a sufficient amount of mixed liquid is contained. In this embodiment, Figure 4 As shown, when the alignment point of the installation position of the movable wheel 314 is less than 2 / 9 of the horizontal length from left to right, the material mixing container 31 is likely to tip over before accommodating a sufficient amount of mixed liquid. If the alignment point of the installation position of the movable wheel 314 is greater than 3 / 9 of the horizontal length from left to right, a large amount of mixed liquid is likely to remain inside the material mixing container 31 after the tipping is completed. Therefore, the installation position of the movable wheel 314 is aligned with the horizontal length of 2 / 9-3 / 9 from left to right of the lower cover 313. In this embodiment, the installation position of the movable wheel 314 is aligned with the horizontal length of 3 / 9 from left to right of the lower cover 313.

[0057] Furthermore, by aligning the raised height of the lower cover 313 close to the opening end of the accommodating chamber with the dividing line between the upper cover 312 and the lower cover 313, and by installing the movable wheel 314, the stability of the mixed liquid during the stirring process is further ensured, and the capacity of the soy milk is increased, and it is not easy for the soy milk to splash out or overflow from the opening when not all the soy milk is added.

[0058] It should be emphasized that the raw material container 2 is connected to the external feeding pipe, so the interior is always kept at 80% full, thereby providing a stable internal pressure.

[0059] When the material mixing container 31 completes mixing, the material box 33 needs to be firmly placed in the material box fixing frame 32. An unobstructed opening is provided on one side of the material box fixing frame 32 for the material box 33 to slide into. The material box 33 can be transported into the material box fixing frame 32 through the unobstructed opening, and the material box 33 is fixed to complete the placement of the material box 33. Each time the empty frame of the material box fixing frame 32 is placed on top, the material box 33 is slid into the material box fixing frame 32 through the unobstructed opening.

[0060] In order to better receive and transfer the material box 33, the material box fixing frame 32 is driven by the corresponding driving cylinder 34, and the material box fixing frame 32 can be raised and lowered by controlling the cylinder. A cross bar 321 is fixedly installed in the middle of the material box fixing frame 32, and the driving cylinder 34 is fixedly installed on the frame 1. A stabilizing frame 35 is fixedly installed at the output end of the driving cylinder 34, and the lower end of the stabilizing frame 35 is fixedly connected to the cross bar 321 in the middle of the material box fixing frame 32.

[0061] Since the material in the material mixing container 31 needs to be poured into the material box 33 during the descent of the material box 33, a connecting member 322 is provided on the side of the material box fixing frame 32 corresponding to the unobstructed opening. The connecting member 322 is rotatably mounted on the lower end of the opening of the material mixing container 31. When the material box fixing frame 32 moves downward, the connecting member 322, which is mounted on the lower end of the opening of the material mixing container 31, can be rotated. The connecting member 322 is used to pull the material mixing container 31 so that when its open end is pulled downward, the opening flips downward and faces the feed end of the material box 33, thereby pouring the mixed material into the material box 33. In this embodiment, the connecting member 322 is a straight rod connected to the connecting ring 31a at the lower end of the opening of the material mixing container 31. In other embodiments, the connecting member 322 can also be two hooks or connecting ring buckles, that is, they can maintain a connection while allowing a certain amount of movement.

[0062] Among them, the input end of the driving cylinder 34 is electrically connected to the output end of the electronic control box 4, and the start and stop of the driving cylinder 34 is controlled by the electronic control box 4, and then the stabilizing frame 35 is controlled to descend through the output end of the driving cylinder 34, and then the material box fixing frame 32 is pulled by the stabilizing frame 35 to drive the material box 33 filled with the mixed liquid to move downward. After releasing the material box 33 filled with the mixed liquid, the material box fixing frame 32 is lifted upward again by controlling the driving cylinder 34.

[0063] In order to prevent the adjacent material boxes 33 from being delivered prematurely during the descent of the material box fixing frame 32, a blocking mechanism 5 is set. The blocking mechanism 5 includes a group of parallel rocker arms 51. One end of the two rocker arms 51 is horizontally connected by an axle rod and is rotatably mounted on the frame 1 through the axle rod. The rocker arm 51 is tilted and fixed with an insert 52 at one end away from the axle rod. The insert 52 is provided with a through portion in the middle of one side close to the rocker arm 51, and a roller 53 is rotatably mounted in the through portion. When the material box fixing frame 32 is at the top, the bottom of the swing rod 51 abuts against the top of the material box fixing frame 32, and then the swing rod 51 is lifted up by the material box fixing frame 32, so that the material box 33 can smoothly enter the material box fixing frame 32; and when the material box fixing frame 32 moves downward, the swing rod 51 that has lost its support rotates downward, and inserts into the material box 33 that has not entered but abutted on the material box fixing frame 32 through the conical shape below the insert 52, and pushes the material box 33 away through the roller 53 to form a blockage.

[0064] Before the material box fixing frame 32 is lifted upward, the material box 33 filled with the mixed liquid material needs to be released, so a push rod 54 is provided between the two lifting rods 353. When the lifting rod 353 rises, the push rod 54 can push the swing plate 51 to flip upward, thereby opening the channel that originally blocked the material box 33 from entering, so that the material box 33 can slide into the material box fixing frame 32 by its own weight.

[0065] In order to ensure that the material box 33 can be circulated and engaged and driven to load the mixed liquid, a group of clamping strips 32b1 are symmetrically installed on the inner side surface of the material box fixing frame 32 adjacent to the unobstructed opening. In order to release the material box 33 onto the discharging conveyor 7 after the material box fixing frame 32 descends, an unobstructed opening for the material box 33 to slide into is provided on one side of the material box fixing frame 32. A group of clamping strips 32b1 are symmetrically fixed on the two inner side surfaces of the material box fixing frame 32 adjacent to the unobstructed opening. The two clamping strips 32b1 clamp the two sides of the material box 33. A connecting piece 322 is provided on the side of the material box fixing frame 32 corresponding to the unobstructed opening. The connecting piece 322 is rotatably mounted on the lower end of the opening of the mixing container 31. A horizontal plate is fixed on the side of the material box fixing frame 32 away from the unobstructed opening, and the bottom of the horizontal plate is higher than the bottom plane of the material box fixing frame 32. Among them, the distance between the two side plates of the material box fixing frame 32 installing the card strip 32b1 is greater than the width of the conveyor belt on the discharge conveyor belt 7. Therefore, when the material box fixing frame 32 is lowered and placed on the conveyor belt on the discharge conveyor belt 7, it can be lowered through the over-position, so that the material box 33 is directly in contact with the conveyor belt, and the transmission belt lifts the material box 33 and breaks away from the constraint of the card strip 32b1, and then when the conveyor belt moves, the material box 33 can be transferred.

[0066] It should be emphasized that when the super position is descending, the cross plate must be kept away from contact with the conveyor belt.

[0067] In order to make the driving cylinder 34 be located on a higher mounting surface, the stabilizing frame 35 includes a support plate 351 welded to the frame 1 and a connecting plate 352 located directly above the support plate 351. The driving cylinder 34 is fixedly connected above the support plate 351, and the output end of the driving cylinder 34 is fixedly connected to the middle of the connecting plate 352. Two lifting rods 353 are vertically installed below the connecting plate 352. The lifting rods 353 pass through the support plate 351 and are welded to the middle cross bar 321 of the material box fixing frame 32. The support plate 351 forms a higher mounting surface, which can keep the driving cylinder 34 away from the humid and hot environment below, further helping to prevent water splashing during the cleaning process of the machine, thereby improving safety in use.

[0068] In order to increase the service life of the driving cylinder 34, the output end of the driving cylinder 34 is facing upward. Therefore, when the driving cylinder 34 is pressurized, the shaft 341 at the output end rises upward, and can drive the material box fixing frame 32 to move upward through the stabilizing frame 35; at this time, the driving cylinder 34 is in a pressure-maintaining state after the pressurization is completed, and is also subjected to the self-weight pressure of the stabilizing frame 35, the material fixing frame 32 and the material box 33. Under the action of double pressure, the internal pressure of the driving cylinder 34 can be increased, thereby improving the stability of the stabilizing frame 35.

[0069] During the pressure release process of the driving cylinder 34, the stabilizing frame 35 drives the material fixing frame 32 to gradually descend. At the same time, as the mixed liquid in the material box 33 gradually increases, the pressure on the driving cylinder 34 increases, so that a pressure balance is formed inside during the pressure release process, which can make the pressure release process more stable, so that the mixed liquid inside the material box 33 can descend more smoothly and is not easy to overflow.

[0070] If the output end of the driving cylinder 34 is set at the bottom, it will become that when the driving cylinder 34 is depressurized, the stabilizing frame 35 drives the material box fixing frame 32 to rise, and when the driving cylinder 34 is punched, the material box fixing frame 32 descends. During this period, the self-weight pressure of the stabilizing frame 35, the material fixing frame 32 and the material box 33 always exerts a downward pulling force on the driving cylinder 34. In the process of the material box 33 descending, it is easy to cause the descent speed to be too fast due to the increase in its own weight, resulting in overflow. In the long run, the long-term application of pulling force is likely to cause the driving cylinder 34 to be overloaded, thereby affecting the service life of the driving cylinder 34. Therefore, in this embodiment, the output end of the driving cylinder 34 is facing upward.

[0071] When the material mixing container 31 pours the mixed liquid into the material box 33, some of it inevitably splashes onto the lifting rod 353, solidifying within a short period of time. To clean this, a sleeve 354 is mounted on the outside of the lifting rod 353, with the top of the sleeve 354 fixedly mounted below the support plate 351. As the lifting rod 353 rises, a scraper sleeve 551 inside the sleeve 55 scrapes away any liquid adhering to the outer surface of the lifting rod 353. The scraper sleeve 551 is made of rubber, effectively keeping the outer surface of the lifting rod 353 clean.

[0072] In order to realize automatic input and automatic output of the material box 33, a first conveyor rack 6 is also included, a first conveyor rack 6 located on one side of the material box fixing frame 32, and a discharge conveyor belt 7 installed inside the frame 1 and below the material box fixing frame 32. Several material boxes 33 are placed above the first conveyor rack 6 and the discharge conveyor belt 7. The material boxes 33 are clamped in the material box fixing frame 32, wherein the first conveyor rack 6 and the discharge conveyor belt 7 are both electrically connected to the electrical control box 4. When the material box fixing frame 32 is in the raised position, the first conveyor rack 6 can be used to start pushing the upper material box 33 into the interior of the material box fixing frame 32; when the material box fixing frame 32 is in the lowered position, the discharge conveyor belt 7 can be used to start pushing the material box 33 placed on the upper conveyor belt to be conveyed to the processing completion area.

[0074] S1, open the first solenoid valve 213 below the soymilk bucket 21 and keep it open for a first preset time to input soymilk into the material mixing container 31;

[0075] S2, opening the third solenoid valve 222 below the additive cylinder 22 for a second preset time, and inputting gypsum liquid into the material mixing container 31 through the second input pipe 221, so that the gypsum liquid is initially mixed with the soy milk to form a preliminary mixed liquid;

[0076] S3, opening the second solenoid valve 214 and keeping it open for a third preset time, soy milk is fed into the material mixing container 31, and the soy milk impacts the preliminary mixed liquid to form a swirling mixed liquid;

[0077] S4, start the first conveyor frame 6 to send the material box 33 into the material box fixing frame 32, so that the material box 33 enters the working area;

[0078] S5, start the driving cylinder 34 to control the material box fixing frame 32 to move downward, and at the same time drive the opening of the material mixing container to rotate, pouring the internal mixed liquid into the material box to complete the slurrying.

[0079] In step S1, the continuous opening time of the first solenoid valve 213 is 0.5s-1s, wherein the input soy milk amount is an estimate, specifically 2 / 10 of the soy milk amount of a single material mixing container 31 filled with soy milk. In order to improve the input efficiency, a large-diameter input port is required. In this embodiment, the specific input port size is 8-12cm. When its diameter is less than 8cm, it takes more time to output the same amount of soy milk. When its diameter is greater than 12cm, the space it occupies is larger and will squeeze the setting space of other output ports. In addition, the soy milk liquid that rushes out instantly has a certain impact force. If the impact force exceeds 12cm, it is too large and easily splashed out. Therefore, in this embodiment, it is further optimized to 10cm.

[0080] In step S2, the second preset time for the continuous opening time of the third solenoid valve 222 is 0.5s-1s, wherein the input additive amount is an estimate, specifically 1 / 10 of the amount of soy milk filled in a single material mixing container 31. In order to improve the input efficiency and have a certain impact force, its input diameter needs to be smaller than the output port controlled by the first solenoid valve 213. In this embodiment, the output port diameter controlled by the third solenoid valve 222 is 1 / 2 of the output port controlled by the first solenoid valve 213.

[0081] In step S3, the second solenoid valve 214 is kept open for a third preset time of 6-8 seconds. The soy milk needs to be discharged with a certain impact force to impact the preliminarily mixed soy milk and tumble it in the material mixing container 31. Therefore, the diameter of the discharge port should be small, specifically 3-5 cm. When the diameter is less than 3 cm, it takes longer to discharge the same amount of soy milk. When the diameter is greater than 5 cm, the impact force is insufficient to fully stir the mixed liquid, making it difficult to generate sufficient swirling force, which affects the final mixing effect. Therefore, in this embodiment, the diameter is further optimized to 5 cm. The corresponding outlet of the dual-outlet housing 212 is equipped with a second solenoid valve 214 for controlling the output state. This valve is used to discharge the soy milk into the material mixing container 31.

[0082] In step S4, the first conveyor frame 6 is started to deliver the material box 33 into the material box fixing frame 32, so that the material box 33 enters the working area; the specific steps are:

[0083] S41 , starting the first conveying rack 6 to convey the material box 33 into the material box fixing frame 32 , and the material box 33 is clamped on the material box 33 through the guide bar 323 .

[0084] In step S5, the mixed liquid in the material mixing container 31 is poured into the material box 33, and the specific steps are as follows:

[0085] S51, the driving cylinder 34 is activated by the electric control box 4, so that the material box fixing frame 32, which is controlled to rise and fall by the driving cylinder 34, carries the material box 33 downward;

[0086] S52 , the open end of the material mixing container 31 gradually tilts as the material box fixing frame 32 descends, and the internal mixed liquid is poured into the material box 33 .

[0087] After step S5, the process further includes step S6, in which the material box fixing frame 32 releases the fully loaded material box 33 and conveys the fully loaded material box 33 to the finishing area via the discharge conveyor belt 7. The specific steps are as follows:

[0088] S61, start the discharge conveyor belt 7 to convey the material box 33 to the finishing area.

[0090] Example 2

[0091] like Figure 6As shown, this embodiment is basically the same as embodiment 1, except that the blocking mechanism includes an N-shaped fixing rod a1 set at the top of the front end of the side plate of the material box fixing frame 32, and a guide roller a2 is rotatably installed on the N-shaped fixing rod a1. The outer fixed sleeve of the guide roller a2 is provided with a corresponding roller a3, and the roller a3 is made of engineering plastic.

[0092] When the material box fixing frame 32 drives the N-shaped fixing rod a1 downward, the roller a3 installed on the guide roller a2 contacts the material box 33, blocking the passage of the material box 33 into the material box fixing frame 32. At the same time, the circular ring surface of the roller a3 can push the material box 33 outward.

[0093] When the material box fixing frame 32 drives the N-shaped fixing rod a1 upward, the passage for the material box 33 to enter the material box fixing frame 32 is reopened, and the material box 33 can slide into the material box fixing frame 32 under the guidance of the material guide chute plate 6 by its own weight.
