Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Currently, hands-free food processors can not only make soy milk, rice paste, and fruit and vegetable juices, but also produce tofu and even douchi (soybean curd) by adding a coagulant after processing. However, due to the size limitations of hands-free products, the effective mixing volume of the grinding chamber is generally around 1.2L. Before making douchi, the soybeans need to be coarsely ground, then heated and soaked at around 70℃ to extract more soy protein and increase the protein content. However, at the same time, the heating and soaking of coarsely ground soybeans at around 70℃ produces a lot of foam, posing a significant risk of overflow. Therefore, the capacity for making douchi in the same model is set at around 700mL. Even with 700mL of material, the amount of douchi formed after coagulation and cooling is generally between 350-400g. Users have reported that the small amount of douchi produced affects the user experience, and they hope to be able to make more douchi at once to meet the breakfast needs of a family of three.

[0003] Patent CN213850315U discloses a food processing machine. The grinding cup includes a lower cup body with a lower cavity and an upper cup body with an upper cavity. The lower cup body is mounted on the main unit with its opening facing upwards. The upper cup body is sealed and fastened to the opening of the lower cup body. The upper cavity and lower cavity communicate to form a mixing chamber. Multiple upper cup bodies are selectively fastened to the opening of the lower cup body, and each upper cup body has a different volume. This design allows for variable volume of the mixing chamber space and significantly reduces the height of the main unit.

[0004] In order to reduce the height of the main unit, this design chooses to directly fasten the upper and lower cup bodies together. As a result, the upper opening of the lower cup body protrudes out of the main unit, while the upper and lower cup bodies are sealed together. With the lower cup body protruding out of the main unit, the sealing part of the upper and lower cup bodies will be exposed above the main unit.

[0005] Because making tofu pudding produces more foam than making soy milk, when using the aforementioned food processor to make tofu pudding, especially when users need to prepare a larger quantity of tofu pudding at once to meet the drinking needs of a family of three, the slurry and foam rise up along the side walls of the lower and upper cups during the tofu pudding process. The heating of the grinding cup creates slurry pressure inside the cup, causing the slurry and foam to seep out directly from the seals of the upper and lower cups, resulting in slurry and stains on the top surface of the main unit or the work surface, causing cleaning trouble for the user. Utility Model Content

[0006] This utility model provides a food processing machine that, in addition to solving the problem that users cannot produce enough tofu pudding in a single batch in the prior art, further solves the problem that during the preparation of large-capacity tofu pudding, the slurry seeps out from the sealed position at the top of the cup, causing slurry and stains on the surface of the main unit and the worktable, which makes cleaning troublesome for users.

[0007] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a main unit with an installation cavity, a cup body installed in the installation cavity, a crushing device located in the cup body, and a driving device for driving the crushing device. The food processing machine also includes a replaceable cup lid and a tofu lid that are fitted onto the cup body. The cup lid is recessed into the installation cavity and seals with the cup body, and the top of the cup lid is flush with the top of the main unit. The tofu lid has an expansion cavity that protrudes upward relative to the main unit, and the lower end of the tofu lid is recessed into the installation cavity and seals with the cup body.

[0008] This invention features replaceable cup lids and a tofu lid, both with their lower ends recessed into the mounting cavity to seal tightly against the cup body. This recessed installation method provides multiple anti-overflow effects whether the cup lid or the tofu lid is closed. Specifically, when the tofu lid is closed, the fit between the lid and the cup body forms the first seal. Simultaneously, because the lower end of the tofu lid is recessed into the mounting cavity, even if there is spillage at the sealing point between the lid and the cup body, the side wall of the mounting cavity forms a second barrier to prevent overflow. This extends the seepage path of foam or material during the preparation of tofu or soy milk, making it more difficult to seep out and significantly reducing the risk of leakage, thus improving the sealing effect. Furthermore, the expanded cavity of the tofu lid can accommodate foam and more material. With the lid recessed into the main unit, it meets the needs of preparing large quantities of tofu at a time while reliably improving the sealing effect to enhance the anti-overflow effect, thus satisfying the user's requirements.

[0009] Furthermore, the lid is recessed into the mounting cavity and seals tightly with the cup body, with the top of the lid flush with the top of the main unit. Even if some liquid spills between the lid and the cup body, the side wall of the mounting cavity provides a second layer of protection against overflow. This also ensures a tight fit between the lid and the mounting cavity, preventing the lid from protruding and taking up extra space. The overall appearance is also cleaner and more streamlined, making cleaning easier for users. Moreover, the flush lid eliminates the risk of bumps and knocks that might occur with a protruding lid, preventing it from becoming loose or shifting and ensuring smooth soy milk preparation.

[0010] In a preferred embodiment, the tofu lid includes a glass lid body with an open lower end, an annular bracket fixed at the open end of the glass lid body, and a sealing ring fixed to the annular bracket. The annular bracket is recessed into the mounting cavity and engages with the inner wall of the mounting cavity, pressing the sealing ring tightly against the upper end face of the cup body.

[0011] The tofu lid employs the aforementioned structure, allowing the annular bracket to sink into the mounting cavity and engage with its inner wall. Simultaneously, this engagement presses the sealing ring tightly against the upper surface of the cup body, causing the sealing ring to deform and form a tight, first-level seal. The engagement of the annular bracket with the inner wall of the mounting cavity then creates a second seal. This ensures a reliable lid fit while enhancing the sealing effect. Furthermore, the glass lid allows for visualization of the manufacturing process, improving the user experience.

[0012] In a preferred embodiment, the glass cover has an outwardly extending flange at its opening, the annular support includes an upper support and a lower support located on both sides of the flange, the sealing ring has an integrally connected sealing part and a mounting part, the sealing part is pressed against the upper end face of the cup body, and the upper support and the lower support clamp and fix the flange and the mounting part together.

[0013] The flange at the opening of the glass cover forms a clamping structure with the upper and lower supports of the annular bracket. Together with the installation part of the sealing ring, it realizes the simultaneous fixation of the sealing ring, the annular bracket, and the glass cover, which facilitates the assembly of the sealing ring and the glass cover. At the same time, when the annular bracket sinks into the installation cavity and snaps into the inner wall, the sealing part can be pressed tightly against the upper end face of the cup. The annular bracket makes the clamping force of the sealing ring uniform in the circumference, avoiding sealing failure due to loose installation, improving the sealing effect, and preventing material spillage.

[0014] In a preferred embodiment, the inner wall of the mounting cavity is provided with a swivel buckle, the cup lid is provided with a first groove that engages with the swivel buckle, and the annular bracket is provided with a second groove that engages with the swivel buckle.

[0015] The screw fasteners on the inner wall of the mounting cavity, along with the first groove of the cup lid and the second groove of the annular bracket, can form a spiral fastening structure. Therefore, the cup lid and the tofu lid are reliably fixed using the same screw fastener on the inner wall of the mounting cavity, simplifying the fixing position of the inner wall of the mounting cavity. Moreover, the cooperation between the screw fasteners and the grooves not only ensures precise fastening of the cup lid and the tofu lid in the circumferential direction of the cup body, but also forms a reliable limit along the axial direction of the cup body through the groove wall. This enhances the connection stability between the tofu lid and the cup body, as well as between the cup lid and the cup body, effectively resisting the upward pushing force generated by foam accumulation during the tofu making process, preventing the lid from loosening and causing sealing failure, improving the reliability of spill prevention, and ensuring the smooth preparation of large-capacity tofu.

[0016] In a preferred embodiment, the annular support includes an annular frame surrounding the glass cover and symmetrical grip handles protruding from both sides of the annular frame. The grip handles include an extension extending from the annular frame toward the top wall of the glass cover and a grip portion bending outward from the extension.

[0017] The ring-shaped bracket of the tofu lid integrates the ring frame and the grip handle. The ring frame provides stable support for the glass lid, laying the foundation for the installation of the sealing ring and the fastening of the tofu lid to the mounting cavity. Moreover, the symmetrically protruding grip handle adopts a bent structure, with the extension extending from the ring frame towards the top wall of the glass lid. This not only adapts to the contour of the glass lid, avoiding excessive radial space occupation, but also creates a gripping area that is easy for the user to hold, improving ease of operation. At the same time, the symmetrically distributed grip handle ensures that the user applies even force, ensuring that the tofu lid is installed properly, thereby guaranteeing the sealing effect. In addition, it makes it easier for the user to open the lid.

[0018] In a preferred embodiment, a sealing ring is fixed to the lower end of the tofu lid. The sealing ring includes a first sealing portion that is pressed against the upper surface of the cup body and a second sealing portion that extends from the first sealing portion to fit against the inner side wall of the cup body.

[0019] The cooperation of the first and second sealing parts creates a more comprehensive and wider-coverage seal between the tofu lid and the cup body. The second sealing part extends from the first sealing part to fit the inner wall of the cup, forming a lateral seal on the internal space of the cup body. This effectively prevents material from climbing up the inner wall of the cup body due to foam during the tofu making process. The first sealing part is pressed tightly against the upper surface of the cup body, directly preventing material from overflowing from the gap between the top of the cup body and the lid. In addition, the mounting cavity of the main unit provides the final protection for the joint between the tofu lid and the cup body, forming a multi-layered sealing effect. This significantly improves the sealing coverage and reliability. With the snap-fit ​​fixing of the ring bracket into the mounting cavity, it ensures that the sealing ring remains tightly fitted to the cup body under foam impact and material pressure, preventing overflow. This makes the food processing machine more effective at preventing overflow when meeting the needs of large-capacity tofu making, ensuring the smooth production of large-capacity tofu.

[0020] In a preferred embodiment, the lower end of the tofu lid is sealed to the upper end of the cup body, and the inner diameter of the lower end of the tofu lid is smaller than the inner diameter of the upper end of the cup body.

[0021] The lower end of the tofu pudding lid is sealed to the upper end of the cup body, and the inner diameter of the lower end of the lid is smaller than the inner diameter of the upper end of the cup body. This design utilizes the contraction of the lid to create a radial contraction barrier at the joint. During the tofu pudding preparation process, when foam rises to the joint between the upper end of the cup body and the lid, the contracted lower end of the lid physically blocks the foam, slowing its upward movement. Simultaneously, the sealed joint allows the foam to flow back into the cup body, preventing it from carrying material out through the joint. This significantly improves spill prevention reliability while meeting the needs of large-capacity tofu pudding preparation.

[0022] More preferably, the tofu lid includes a glass lid body with an open lower end and an annular bracket fitted and fixed to the lower end of the glass lid body. The glass lid body is sealed and pressed against the upper end of the cup body through the annular bracket, so that the opening of the glass lid body shrinks relative to the inner diameter of the opening of the cup body.

[0023] By setting up a ring-shaped support, on the one hand, the pressing action of the ring-shaped support forms a seal between the glass lid and the cup, preventing the material from overflowing from the gap between the two; on the other hand, the inner diameter contraction structure of the open glass lid can physically block the foam that rises during the tofu making process, breaking the foam and effectively cutting off the path for the foam to continue to overflow upwards.

[0024] In a preferred embodiment, the volume of the expansion cavity is 300-600 ml.

[0025] By employing an expansion chamber of 300-600ml, the overall pulping volume is increased based on the original cup volume. This allows the food processor to handle larger initial material volumes, significantly increasing the amount of tofu pudding produced per batch. This satisfies the breakfast needs of a family of three, completely resolving the user experience issue caused by insufficient tofu pudding quantity. If the expansion chamber volume is less than 300ml, the amount of soy milk produced per batch is generally sufficient for a family of three. Even if it's insufficient for more users, users can manually mix more or use a food processor with a mixing cup to produce a larger batch. However, if the expansion chamber volume is less than 300ml, the volume of the tofu pudding after solidification may still be insufficient to meet the basic breakfast needs of a family of three. The 300-600ml capacity is sufficient to meet the needs of a family of three. If the capacity of the expansion chamber exceeds 600ml, the whole machine will be too big and inconvenient to store. Moreover, the extra space will not only fail to improve the preparation efficiency, but will also increase the difficulty of cleaning.

[0026] In a preferred embodiment, the tofu lid is provided with baffles located on the inner wall of the expansion cavity, and a plurality of baffles are arranged at intervals along the circumference.

[0027] The baffle ribs effectively interfere with the foam rising into the expansion chamber. When the foam generated during the tofu making process enters the expansion chamber with the material, it is blocked and diverted by the baffle ribs. The originally gathered foam is dispersed and cut, and some foam breaks after colliding with the baffle ribs, reducing the overall volume of the foam and the upward impact force. At the same time, the baffle ribs can also change the material flow path in the expansion chamber, slow down the rising speed of the foam, and prevent a large amount of foam from concentrating and impacting the sealing structure, further improving the spill prevention reliability when making large-capacity tofu. They also play a baffle role to improve the crushing efficiency. Attached Figure Description

[0035] like Figure 1-4As shown, this utility model provides a food processing machine, including a main unit 10 with an installation cavity 101, a cup body 20 installed in the installation cavity 101, a crushing device 50 located in the cup body 20, and a driving device 60 for driving the crushing device 50. The food processing machine also includes a replaceable cup lid 30 and a tofu lid 40 that are fitted over the cup body 20. The cup lid 30 is sunken into the installation cavity 101 and sealed to the cup body 20, and the top of the cup lid 30 is flush with the top of the main unit 10. The tofu lid 40 is provided with an expansion cavity 401 that protrudes upward relative to the main unit 10, and the lower end of the tofu lid 40 is sunken into the installation cavity 101 and sealed to the cup body 20.

[0036] This invention features replaceable cup lid 30 and tofu lid 40, both with their lower ends recessed into the mounting cavity 101 to seal and cover the cup body 20. This recessed installation method creates multiple anti-overflow effects whether the cup lid 30 or the tofu lid 40 is closed. Specifically, when the tofu lid 40 is closed, the sealing fit between the tofu lid 40 and the cup body 20 forms the first seal. Simultaneously, because the lower end of the tofu lid 40 is recessed into the mounting cavity 101, even if there is spillage at the sealing position between the tofu lid 40 and the cup body 20, the side wall of the mounting cavity forms a second layer of protection against spillage. This extends the seepage path of foam or material during the preparation of tofu or soy milk, making it more difficult to seep out, greatly reducing the risk of seepage and improving the sealing effect. Meanwhile, the expansion chamber 401 of the tofu lid 40 can accommodate foam and more materials. When it sinks into the main unit 10, it can meet the needs of preparing large-capacity tofu in a single batch, and reliably improve the sealing effect to enhance the anti-overflow effect, thus meeting the user's needs.

[0037] Furthermore, the lid 30 is recessed into the mounting cavity 101 and seals tightly with the cup body 20, with the top of the lid 30 flush with the top of the main unit 10. Even if some liquid spills between the lid 30 and the main unit 10, the side wall of the mounting cavity can still provide a second layer of protection against spillage. This also ensures a tight fit between the lid 30 and the mounting cavity 101, preventing the lid 30 from protruding and taking up extra space. The overall appearance is also cleaner and more streamlined, making it easier for users to wipe and clean. Moreover, the flush lid 30 eliminates the risk of bumps and knocks that might result from a protruding lid 30, preventing it from becoming loose or shifting and ensuring smooth soy milk preparation.

[0038] like Figure 1 As shown, in a preferred embodiment, the cup lid 30 and the tofu lid 40 are screwed onto the main unit, the inner wall of the mounting cavity 101 is provided with a buckle 102, the cup lid 30 is provided with a first groove that cooperates with the buckle 102, and the annular bracket 42 is provided with a second groove that cooperates with the buckle 102.

[0039] The screw fastener 102 on the inner wall of the mounting cavity 101 can form a screw fastener 102 engagement structure with the first groove of the cup lid 30 and the second groove of the annular bracket 42, respectively. Therefore, the cup lid 30 and the tofu lid 40 are reliably fixed by the same screw fastener 102 on the inner wall of the mounting cavity 101, simplifying the fixing position of the inner wall of the mounting cavity 101. Moreover, the cooperation of the screw fastener 102 and the groove not only ensures the precise engagement position of the cup lid 30 and the tofu lid 40 in the circumferential direction of the cup body 20, but also forms a reliable limit along the axial direction of the cup body 20 through the groove wall, thereby enhancing the connection stability between the tofu lid 40 and the cup body 20, as well as between the cup lid 30 and the cup body 20. This effectively resists the upward pushing force generated by the accumulation of foam during the tofu making process, avoids the lid from loosening and causing sealing failure, improves the reliability of spill prevention, and ensures the smooth preparation of large-capacity tofu.

[0040] like Figure 4 As shown, in a preferred embodiment, the lower end of the tofu lid 40 is sealed and connected to the upper end of the cup body 20, and the inner diameter D1 of the lower end of the tofu lid 40 is smaller than the inner diameter D2 of the upper end of the cup body 20. More preferably, in this embodiment, the tofu lid 40 includes a glass lid 41 with an open lower end and an annular support 42 fitted and fixed to the lower end of the glass lid 41. The glass lid 41 is sealed and pressed against the upper end of the cup body 20 by the annular support 42, causing the opening of the glass lid 41 to contract relative to the inner diameter of the opening of the cup body 20.

[0041] The lower end of the tofu lid 40 is sealed to the upper end of the cup body 20, and the inner diameter of the lower end of the tofu lid 40 is smaller than the inner diameter of the upper end of the cup body 20. This creates a radial contraction barrier at the point of contact between the tofu lid 40 and the cup body 20. During the tofu preparation process, when foam rises to the point of contact between the upper end of the cup body 20 and the tofu lid 40, the contracted lower end of the tofu lid 40 physically blocks the foam, slowing its upward movement. Simultaneously, the sealed connection between the tofu lid 40 and the cup body 20 allows the foam to flow back into the cup body 20, preventing it from carrying material out through the seam. This significantly improves spill prevention reliability while meeting the needs of large-capacity tofu preparation. On the one hand, the pressing action of the ring bracket 42 makes the glass cover 41 and the cup 20 form a seal, preventing the material from overflowing from the gap between the two; on the other hand, the inner diameter contraction structure of the open glass cover 41 can physically block the foam that rises during the tofu making process, which can break the foam and effectively cut off the path for the foam to continue to overflow upwards.

[0042] like Figure 4 As shown, preferably, the tofu lid 40 is provided with a flow-dispersing rib 44 located on the inner wall of the expansion cavity 401, and multiple flow-dispersing ribs 44 are arranged at intervals along the circumference.

[0043] The baffle 44 effectively interferes with the foam rising into the expansion chamber 401. When the foam generated during the tofu making process enters the expansion chamber 401 with the material, it is blocked and diverted by the baffle 44. The originally gathered foam is dispersed and cut, and some foam breaks after colliding with the baffle 44, reducing the overall volume of the foam and the upward impact force. At the same time, the baffle 44 can also change the material flow path in the expansion chamber 401, slow down the rising speed of the foam, and avoid a large amount of foam from concentrating and impacting the sealing structure, further improving the spill prevention reliability when making large-capacity tofu, while also playing a baffle role to improve the crushing efficiency.

[0044] like Figure 5 , 6 As shown in Figures 7 and 8, in a preferred embodiment, the tofu lid 40 includes a glass lid body 41 with an open lower end, an annular bracket 42 fixed at the open end of the glass lid body 41, and a sealing ring 43 fixed to the annular bracket 42. The annular bracket 42 is recessed into the mounting cavity 101 and engages with the inner wall of the mounting cavity 101, pressing the sealing ring 43 against the upper end face of the cup body 20.

[0045] Specifically, such as Figure 6 , 7 As shown, the glass cover 41 has an outwardly extending flange 411 at its opening. The annular support 42 includes an upper support 421 and a lower support 422 located on both sides of the flange 411. The sealing ring 43 has an integrally connected sealing part 431 and mounting part 432. Figure 6 The sealing part 431 is pressed against the upper end face of the cup body 20, and the upper bracket 421 and the lower bracket 422 clamp and fix the flange 411 and the mounting part 432 together.

[0046] The tofu lid 40 adopts the above-described structure, allowing the annular bracket 42 to sink into the mounting cavity 101 and engage with the inner wall of the mounting cavity 101. Simultaneously, as the two engage, the sealing ring 43 is pressed tightly against the upper surface of the cup body 20. This deformation of the sealing ring 43 creates a tight, first-level seal with the cup body 20. The engagement of the annular bracket 42 with the inner wall of the mounting cavity 101 forms a second-level seal. This ensures reliable lid closure while improving the sealing effect. Furthermore, the use of a glass lid 41 allows for visualization of the manufacturing process, enhancing the user experience.

[0047] The flange 411 at the opening of the glass cover 41 forms a clamping structure with the upper and lower supports 422 of the annular bracket 42. Together with the mounting part 432 of the sealing ring 43, the sealing ring 43, the annular bracket 42, and the glass cover 41 are simultaneously fixed, which facilitates the assembly of the sealing ring 43 and the glass cover 41. At the same time, when the annular bracket 42 sinks into the mounting cavity 101 and snaps into the inner wall, the sealing part 431 can be pressed tightly against the upper end face of the cup body 20. The annular bracket 42 makes the pressing force of the sealing ring 43 uniform in the circumference, avoiding the sealing part 431 from failing due to loose installation, improving the sealing effect and preventing the material from overflowing.

[0048] like Figure 6 As shown, in a preferred embodiment, the annular support 42 includes an annular frame surrounding the glass cover 41 and grip handles 423 symmetrically protruding from both sides of the annular frame. Each grip handle 423 includes an extension 4231 extending from the annular frame towards the top wall of the glass cover 41 and a gripping portion 4232 bent outward from the extension 4231. More specifically, in this embodiment, the annular frame includes an upper support 421 and a lower support 422, with the grip handles 423 disposed on the upper support 421.

[0049] The annular bracket 42 of the tofu lid 40, through the integrated design of the annular frame and the grip handle 423, uses the annular frame to achieve stable surrounding support for the glass lid 41, providing a foundation for the installation of the sealing ring 43 and the fastening of the tofu lid 40 with the mounting cavity 101. Moreover, the symmetrically protruding grip handle 423 adopts a bent structure, with the extension 4231 extending from the annular frame towards the top wall of the glass lid 41. This not only adapts to the contour of the glass lid 41, avoiding occupying too much radial space, but also forms a gripping area that is easy for the user to grasp through the outwardly bent grip part 4232, improving the ease of operation. At the same time, the symmetrically distributed grip handles 423 ensure that the user applies force evenly, ensuring that the tofu lid 40 is installed in place, thereby ensuring the sealing effect. In addition, it makes it easier for the user to open the lid.

[0050] like Figure 6 As shown, in a preferred embodiment, a sealing ring 43 is fixed to the lower end of the tofu lid 40. The sealing ring 43 includes a first sealing part 431 that is pressed against the upper surface of the cup body 20. When the tofu lid 40 is not closed, the first sealing part 431 arches downward to form a movable cavity on the upper side. When the tofu lid 40 is closed, the first sealing part 431 flexibly deforms to seal between the tofu lid 40 and the cup body 20.

[0051] Of course, in a more preferred embodiment, the sealing ring 43 further includes a second sealing portion 431 extending from the first sealing portion 431 to fit against the inner wall of the cup body 20.

[0052] The cooperation of the first sealing part 431 and the second sealing part 431 forms a more comprehensive and wider-coverage seal between the tofu lid 40 and the cup body 20. The second sealing part 431 extends from the first sealing part 431 to fit the inner wall of the cup body 20, forming a lateral seal on the internal space of the cup body 20. This effectively prevents material from climbing up the inner wall of the cup body 20 due to foam during the tofu making process. The first sealing part 431 is pressed tightly against the upper surface of the cup body 20, which can directly block the material from entering through the gap between the top of the cup body 20 and the lid. Overflow, plus the final protection of the joint between the tofu lid 40 and the cup body 20 by the mounting cavity 101 of the main unit 10, forms a multi-layer sealing protection effect, which greatly improves the sealing coverage and reliability. With the snap-fit ​​fixation of the ring bracket 42 into the mounting cavity 101, it can ensure that the sealing ring 43 always maintains a tight fit with the cup body 20 under foam impact and material pressure, avoiding overflow. This makes the food processing machine more effective in preventing overflow when meeting the needs of large-capacity tofu preparation, ensuring the smooth production of large-capacity tofu.

[0053] In a preferred embodiment, the volume of the expansion cavity 401 is 300-600ml. For example, if the volume of the expansion cavity 401 is 300ml, it can produce about 600g of tofu pudding, which can meet the breakfast needs of a family of three.

[0054] Of course, the expansion chamber can also be 400ml or 600ml.

[0055] Optionally, the food processor includes multiple tofu lids of different volumes, allowing users to choose flexibly according to the number of people.

[0056] By employing an expansion chamber 401 with a capacity of 300-600ml, the overall pulping volume is expanded from the original 20ml cup volume. This allows the food processor to handle larger initial material volumes, significantly increasing the amount of tofu pudding produced per batch. This satisfies the breakfast needs of a family of three, completely resolving the user experience issue caused by insufficient tofu pudding quantity. If the expansion chamber 401's volume is less than 300ml, the amount of soy milk produced per batch is generally sufficient for a family of three. Even if it's insufficient for more users, users can manually mix more or use a food processor with a mixing cup to produce a larger batch. However, if the expansion chamber 401's volume is less than 300ml, the volume of the tofu pudding after solidification may still be insufficient to meet the basic breakfast needs of a family of three. The 300-600ml capacity is sufficient to meet the needs of a family of three. If the capacity of the expansion chamber 401 exceeds 600ml, the whole machine will be too big and inconvenient to store. Moreover, the extra space will not only fail to improve the preparation efficiency, but will also increase the difficulty of cleaning.

[0057] It should also be noted that the food processing machine provided by this utility model does not limit the specific method of preparing tofu pudding. In a preferred embodiment, such as... Figure 4 As shown, the pulverizing device 50 is a pulverizing blade or a moving grinding head, and the driving device 60 is a motor. The motor drives the pulverizing device 50 to rotate to pulverize the soybean material added to the cup. The food processor also includes a liquid receiving cup, with a drain valve on the cup body. The liquid receiving cup 70 is located below the drain valve to receive the slurry processed in the cup body. More preferably, the food processor also includes a filter screen 80, which overlaps the mouth of the liquid receiving cup 70. The user can put a coagulant on the filter screen 80. When the drain valve is opened to drain the liquid, the soybean liquid and the coagulant mix and enter the liquid receiving cup 70, where it then coagulates to form tofu.
