Description

Technical Field

[0001] The invention relates to the field of food dipping sauce processing, in particular to a food dipping sauce anti-settling transfer device. Background Art

[0002] In the process of producing food dipping sauces, depending on the different production process flows, it is often necessary to transfer or cache the dipping sauces through a transfer device. However, there is a common problem in the prior art in this link, that is, the lack of effective cooling and preservation functions. The structure of these transfer devices is relatively simple, usually consisting only of a conventional tank body. Not only can they not cool the cached dipping sauces in a timely and effective manner, but they also have poor isolation from the air. The dipping sauces are easily oxidized by the oxygen in the air mixed into the tank body, resulting in changes in the expected flavor characteristics of the dipping sauces, and failing to provide consumers with a stable and high-quality taste experience.

[0003] In addition, food dips are often made from a mixture of materials with different densities. After a long period of storage, the denser materials will gradually settle, resulting in stratification of the dips. This stratification will directly have a negative impact on the taste of the food dips, making it difficult for consumers to get a uniform and harmonious taste experience when eating.

[0044] When the sauce in the storage space needs to be cooled and preserved, liquid nitrogen can be introduced into the cylinder. Liquid nitrogen absorbs heat during the vaporization process, thereby cooling the sauce. At the same time, the vaporized nitrogen will enter the storage space, effectively reducing the oxygen content in the storage space, thereby slowing down the speed at which the sauce is oxidized by oxygen.

[0045] In addition, when the dipping sauce is cooled by liquid nitrogen, the volume expansion caused by the gasification of liquid nitrogen will push the piston to reciprocate up and down. The up and down reciprocating motion of the piston is converted by the conversion structure into the rotational motion of the active ring along the first rotation direction. The rotation of the active ring further drives the first stirring blade to rotate, stirring the dipping sauce in the storage space. This not only improves the cooling efficiency, but also can further stir the dipping sauce during the cooling process, which helps to delay the sedimentation of the dipping sauce.

[0046] Among them, when the temperature of the dipping sauce decreases, the viscosity of the dipping sauce will increase, and the increase in viscosity helps to slow down the sedimentation rate of high-density materials in the dipping sauce, thereby reducing the negative impact of sedimentation on the taste of the food dipping sauce during long-term storage.

[0047] In summary, the food dipping sauce anti-settling transfer device provided in the present application has the advantages of preventing the dipping sauce from settling and efficiently preserving the food. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0059] The drawings are only used for illustrative purposes and should not be construed as limitations of this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product.

[0060] For those skilled in the art, it is understandable that some well-known structures and their descriptions may be omitted in the drawings. The technical solution of the present invention is further described below in conjunction with the drawings and embodiments.

[0061] To solve these problems mentioned in the background technology, the applicant proposes the following Figure 1-6The anti-settling transfer device for food dipping sauce shown in the figure comprises a tank body 1, a storage space 13 is provided in the tank body 1, a feed pipe 11 and a discharge pipe 12 are provided at the top and bottom of the tank body 1 respectively, and a first stirring mechanism and a second stirring mechanism are provided in the tank body 1. The first stirring mechanism comprises a vertically extending cylinder 141, the cylinder 141 is thermally connected to the storage space 13, a piston 142 is sealed and slidably connected in the cylinder 141, the cylinder 141 is connected to a liquid supply pipe 143 through a first control valve structure, and the cylinder 141 is connected to the storage space 13 through a second control valve structure. An active ring 1411 is rotatably connected to the cylinder 141, and a motion conversion structure is connected between the piston 142 and the active ring 1411, and the motion conversion structure is used to convert the up and down reciprocating motion of the piston 142 into the rotational motion of the active ring 1411 along the first rotation direction. The active ring 1411 is connected to the first stirring blade 144 through an energy storage component. When the first stirring blade 144 rotates along the first rotation direction relative to the active ring 1411, the energy storage component stores energy. The second stirring mechanism includes a second stirring blade 31 and a motor 32 capable of driving the second stirring blade 31 to rotate along the first rotation direction. The outer side of the tank body 1 is provided with a heat insulation sleeve 74, and a heating chamber 71 is provided between the heat insulation sleeve 74 and the tank body 1. The heating chamber 71 is connected to a medium input connector 74 and a medium output connector 73.

[0062] The tank 1 is a container for storing and transferring food dips, which can be realized by a cylindrical structure made of stainless steel. The first stirring mechanism is a stirring mechanism driven by the reciprocating motion of the piston 142, which can be realized by components such as a cylinder 141, a piston 142, a motion conversion structure and a first stirring blade 144.

[0063] The second stirring mechanism is a stirring mechanism driven by the motor 32 , and can be specifically implemented by the motor 32 and the second stirring blade 31 .

[0064] The first stirring mechanism converts the linear motion into rotational motion through the reciprocating motion of the piston 142 and the motion conversion structure, driving the first stirring blade 144 to stir. At the same time, the design of the energy storage component allows the storage and release of energy, which improves the continuity and efficiency of stirring. The second stirring mechanism provides additional stirring to further ensure the uniformity of the dipping sauce. In addition, the thermal connection between the cylinder 141 and the storage space 13 allows the low temperature of the liquid nitrogen to be transferred to the food dipping sauce, which helps to maintain the appropriate temperature of the dipping sauce.

[0065] When in use, first, the dip enters the storage space 13 of the tank body 1 through the feed pipe 11, and the liquid supply pipe 143 transfers the liquid nitrogen to the cylinder 141. The heat-conducting connection between the cylinder 141 and the storage space 13 allows heat to be transferred between the two. The liquid nitrogen in the cylinder 141 absorbs heat and vaporizes, which helps to maintain the appropriate temperature of the dip. The piston 142 in the cylinder 141 begins to reciprocate up and down under the nitrogen pressure formed after the liquid nitrogen provided by the liquid supply pipe 143 is vaporized. The reciprocating motion of the piston 142 is converted into the rotational motion of the active ring 1411 through the motion conversion structure. The active ring 1411 drives the first stirring blade 144 to rotate to stir the dip in the storage space 13. In other embodiments, the liquid supply pipe 143 can also transport liquid carbon dioxide to the cylinder 141.

[0066] When the device is discharging, the motor 32 drives the second stirring blade 31 to rotate, providing additional stirring power, and the energy storage component stores part of the kinetic energy of the second stirring blade 31 to facilitate subsequent discharging operations. At the same time, the insulation sleeve 74 and the heating chamber 71 structure on the outside of the tank body 1 can control the temperature of the food sauce in the tank body 1. The heating medium can be input or output into or out of the heating chamber 71 through the medium input connector 74 and the medium output connector 73, thereby adjusting the temperature of the food sauce in the tank body 1. When discharging is required, the food sauce is heated up to facilitate the discharge of the food sauce. The insulation sleeve 74 can be made of foamed polyurethane or vacuum insulation material, and the thickness can be controlled between 20-50 mm to provide a good thermal insulation effect.

[0067] In some embodiments, the stroke of the piston 142 is provided with a starting point position, a lower dead point position and an upper dead point position; when the piston 142 is at the starting point position, the first control valve structure connects the cylinder 141 and the liquid supply pipe 143, and the second control valve structure blocks the cylinder 141 and the storage space 13; when the piston 142 is at the lower dead point position, the first control valve structure blocks the cylinder 141 and the liquid supply pipe 143, and the second control valve structure blocks the cylinder 141 and the storage space 13; when the piston 142 is at the upper dead point position, the first control valve structure connects the cylinder 141 and the liquid supply pipe 143, and the second control valve structure connects the cylinder 141 and the storage space 13; the piston 142 is connected to an elastic component, which makes the piston 142 tend to remain at the starting point position; the elastic component includes a first elastic member 1421 connected to the top end of the piston 142, and a second elastic member 1422 connected to the bottom end of the piston 142.

[0068] In this embodiment, by setting the starting point position, the bottom dead point position and the top dead point position on the stroke of the piston 142, and by controlling the switch states of the first control valve structure and the second control valve structure when the piston 142 is at different positions, the precise control of the movement of the piston 142 is achieved. The setting of the elastic component makes the piston 142 have a tendency to remain at the starting point position, which contributes to the stability and controllability of the piston 142. The first elastic member 1421 and the second elastic member 1422 are respectively connected to the top and bottom ends of the piston 142, which can provide appropriate buffering and resilience when the piston 142 moves up and down, further improving the stability and reliability of the movement of the piston 142.

[0069] When the piston 142 is at the starting point, the liquid supply pipe 143 injects liquid nitrogen into the cylinder 141. Since the second control valve structure blocks the cylinder 141 and the storage space 13, the nitrogen generated after the liquid nitrogen vaporizes cannot be discharged into the storage space 13, thereby gradually pushing the piston 142 to move upward to the top dead center. When the piston 142 reaches the top dead center, the first control valve structure connects the cylinder 141 and the liquid supply pipe 143, and the second control valve structure connects the cylinder 141 and the storage space 13, and the gas in the cylinder 141 is discharged into the storage space 13. As the liquid nitrogen flows into the cylinder 141, the volume of the gas in the cylinder 141 decreases at low temperature, forming a negative pressure in the cylinder 141, and moves downward to the bottom dead center under the joint action of the first elastic member 1421. At the bottom dead center, in order to prevent excessive liquid nitrogen from flowing into the cylinder 141, the first control valve structure blocks the cylinder 141 and the liquid supply pipe 143, and the piston 142 returns to the starting point under the elastic force of the second elastic member 1422. In this way, the piston 142 reciprocates and moves by the pressure of the gasified liquid nitrogen.

[0070] In some embodiments, the first control valve structure includes a core rod 145 connecting the tank body 1 and the cylinder 141, a liquid inlet channel 1451 is provided in the core rod 145, a liquid inlet hole 1452 connected to the liquid inlet channel 1451 is opened on the side wall of the core rod 145, a sealing cylinder 146 is provided on the outer sliding sleeve of the core rod 145, a driven shoulder 1461 is provided on the sealing cylinder 146, and a first push shoulder 1423 and a second push shoulder 1424 cooperating with the driven shoulder 1461 are provided on the piston 142.

[0071] By directly controlling the opening and closing of the first control valve structure by utilizing the movement of the piston 142, the effects of simple structure, precise control and rapid response are achieved. The core rod 145 connects the tank body 1 and the cylinder 141, and is provided with a liquid inlet 1451 inside. The side wall is provided with a liquid inlet hole 1452 connected to the liquid inlet 1451 for the circulation of liquid. The plugging cylinder 146 is slidably sleeved on the outside of the core rod 145, and is provided with a driven shoulder 1461 for controlling the opening and closing of the liquid inlet hole 1452. The piston 142 is provided with a first push shoulder 1423 and a second push shoulder 1424. When not pushed by the first push shoulder 1423 or the second push shoulder 1424, the plugging cylinder 146 and the core rod 145 remain stationary. The driven shoulder 1461 of the plugging cylinder 146 can be designed as an annular structure, and its outer diameter is slightly smaller than the inner diameter of the cylinder 141 to ensure that it can slide freely in the cylinder 141. The first push shoulder 1423 and the second push shoulder 1424 on the piston 142 may be designed as an annular structure matching the driven shoulder 1461 .

[0072] When the piston 142 rises, the first push shoulder 1423 pushes the blocking tube 146 upward to open the liquid inlet hole 1452; when the piston 142 descends, the second push shoulder 1424 pushes the blocking tube 146 downward to close the liquid inlet hole 1452. At this time, the liquid nitrogen in the liquid supply pipe 143 cannot flow into the cylinder 141.

[0073] In some embodiments, the second control valve structure includes an exhaust duct 21 opened on the cylinder 141, a check member 22 is provided in the exhaust duct 21, a sealing plate 23 is slidably connected to the cylinder 141, an air hole 231 is opened on the sealing plate 23, and the sealing plate 23 is connected to a third elastic member 24, and the third elastic member 24 enables the sealing plate 23 to maintain a tendency to move to a position where the air hole 231 and the exhaust duct 21 are staggered; a push block 1425 cooperating with the sealing plate 23 is provided on the piston 142.

[0074] The exhaust passage 21 is provided on the cylinder 141 and is used to discharge the nitrogen gas after the liquid nitrogen in the cylinder 141 is gasified. The exhaust passage 21 can be provided at the upper part of the cylinder 141 to facilitate the discharge of the gas. Discharging the nitrogen gas into the storage space 13 can improve the protection effect of the food dipping sauce and the preservation effect of the food dipping sauce; it can also increase the air pressure in the storage space 13, and avoid the liquid surface of the dipping sauce from shaking significantly during the movement of the device.

[0075] The check member 22 is arranged in the exhaust duct 21, and its main function is to prevent the gas in the storage space from flowing back into the cylinder 141. The check member 22 can take various forms, such as a one-way valve, a ball valve or a spring valve. The sealing plate 23 is slidably connected to the cylinder 141 to control the opening and closing of the exhaust duct 21. The material of the sealing plate 23 is selected to have good sealing and wear resistance to ensure that a good sealing effect can be achieved when the exhaust duct 21 is completely covered. The air hole 231 is opened on the sealing plate 23, and its function is to allow gas to pass through when it is aligned with the exhaust duct 21 at a specific position. The third elastic member 24 is connected to the sealing plate 23 to keep the sealing plate 23 at a position where the air hole 231 is staggered from the exhaust duct 21.

[0076] When the piston 142 rises, the push block 1425 pushes the blocking plate 23 to align the air hole 231 with the exhaust duct 21, allowing the gas to be discharged. At this time, the check member 22 is opened, and the gas can be discharged from the exhaust duct 21. When the piston 142 descends, the third elastic member 24 returns the blocking plate 23 to the initial position and closes the gas passage. At the same time, the check member 22 is closed to prevent external gas from entering the cylinder 141. It can not only effectively control the emission of gas, but also prevent external gas from entering the cylinder 141, ensuring the normal operation of the device and the quality of the food dipping sauce.

[0077] In some embodiments, the motion conversion structure includes a guide groove 1426 provided on the outer wall of the piston 142, and a guide pin 1412 provided on the inner wall of the active ring 1411 and slidably connected to the guide groove 1426; the guide groove 1426 includes multiple ends of inclined sections and vertical sections that are alternately distributed along the circumference of the piston 142 and connected end to end in sequence, the groove depth of the vertical section gradually changes along the vertical direction, the groove depth at the bottom end of the vertical section is greater than or equal to the groove depth of the inclined section, and the groove depth at the top end of the vertical section is less than the groove depth of the inclined section; a spring member 1413 is connected between the guide pin 1412 and the active ring 1411, and the spring member 1413 makes the guide pin 1412 tend to approach the axis line of the active ring 1411.

[0078] The above arrangement converts the up and down reciprocating motion of the piston 142 into the rotational motion of the active ring 1411. The guide groove 1426 is the core of the structure. The guide groove 1426 includes a plurality of inclined segments and vertical segments that are alternately distributed along the circumference of the piston 142 and connected end to end in sequence. This design enables the guide pin 1412 to move in the guide groove 1426 when the piston 142 moves up and down, thereby driving the active ring 1411 to rotate. The inclined segment is mainly responsible for converting the vertical motion of the piston 142 into the rotational motion of the active ring 1411, while the vertical segment plays a resetting role when the piston 142 moves downward.

[0079] The groove depth of the vertical section gradually changes along the vertical direction, the groove depth at the bottom end is greater than or equal to the groove depth of the inclined section, and the groove depth at the top end is less than the groove depth of the inclined section. The radial position of the guide pin 1412 is adjusted by changing the groove depth, so that the guide pin 1412 can move more stably from the vertical section to the inclined section. By utilizing the characteristics of the mechanical structure, a simple and efficient motion conversion is achieved. Through the special design of the guide groove 1426 and the use of the spring member 1413, the present application not only solves the problem of converting the up and down reciprocating motion of the piston 142 into the rotational motion of the active ring 1411, but also improves the conversion efficiency and stability.

[0080] Furthermore, no matter whether the piston 142 moves upward or downward, the active ring 1411 will keep rotating in the same direction. This is very important for the food sauce anti-settling transfer device that needs to be continuously stirred, and can ensure the continuity and uniformity of the stirring process.

[0081] In some embodiments, the energy storage assembly includes a driven ring 41 rotatably connected to the cylinder 141, and a spring 42 connecting the active ring 1411 and the driven ring 41; a bite structure is provided between the active ring 1411 and the driven ring 41, and the bite structure has a first state and a second state; when the bite structure is in the first state, the bite structure limits the rotation of the driven ring 41 relative to the active ring 1411 along the second rotation direction; when the bite structure is in the second state, the bite structure releases the restriction on the rotation of the driven ring 41; the bite structure includes a bite ring 43 movably sleeved on the active ring 1411, an outer spline 1414 is provided on the outer side wall of the active ring 1411, an inner spline 431 matching the outer spline 1414 is provided on the inner side wall of the bite ring 43, and the driven ring 41 A ratchet 411 is provided on the inner wall, and a pawl 432 cooperating with the ratchet 411 is provided on the outer wall of the bite ring 43; when the bite structure is in the first state, the inner spline 431 is meshed with the outer spline 1414, and the pawl 432 is meshed with the ratchet 411; when the bite structure is in the second state, the inner spline 431 is separated from the outer spline 1414, and the pawl 432 is separated from the ratchet 411; a vertically extending push rod 147 is slidably connected in the cylinder 141, and the bottom end of the push rod 147 extends into the storage space 13 and is connected to a float 1471, and the top end of the push rod 147 abuts against the bite ring 43; a first elastic member 44 is connected between the active ring 1411 and the bite ring 43, and the first elastic member 44 makes the bite ring 43 tend to move away from the active ring 1411.

[0082] In some embodiments, the energy storage assembly includes a driven ring 41 and a mainspring 42, and the rotation of the driven ring 41 is controlled by a bite structure. The bite structure has two states, the first state restricts the reverse rotation of the driven ring 41, and the second state releases the restriction. The bite structure is composed of a bite ring 43, an external spline 1414, an internal spline 431, a ratchet 411 and a pawl 432, and different states are achieved by engagement or separation. The push rod 147 and the float 1471 are used to sense the liquid level of the storage space 13 and control the position of the bite ring 43. The first elastic member 44 keeps the bite ring 43 away from the active ring 1411.

[0083] When the device is loaded with materials, the liquid level in the storage space 13 gradually rises, so that the bite structure is in the first state, and the up and down movement of the piston 142 drives the first stirring blade 144 to rotate, so that the dip is evenly cooled, and the clockwork 42 will not be tightened at this time.

[0084] When the device is discharging, the motor 32 drives the second stirring blade 31 to rotate, and the eddy current generated by the rotation will drive the driven ring 41 to rotate in the first rotation direction. During this process, the spring 42 is gradually tightened, and because the bite structure restricts the driven ring 41 from rotating in the second rotation direction relative to the active ring 1411, the energy stored in the spring 42 cannot be directly released. As the liquid level in the storage space 13 drops, the float 1471 drops, causing the bite structure to change from the first state to the second state. At this time, the energy stored in the spring 42 drives the driven ring 41 to rotate in the first direction, thereby driving the first stirring mechanism to rotate and scrape off the food sauce remaining on the side wall of the storage space 13, which is convenient for subsequent discharge.

[0085] This design realizes the storage and release control of the energy of the energy storage component through the two states of the bite structure. When the bite structure is in the first state, the driven ring 41 is restricted to rotate in one direction, and energy can be stored. When the energy needs to be released, the bite structure switches to the second state, and the restriction on the driven ring 41 is released. The design of the push rod 147 and the float 1471 enables the device to automatically adjust the state of the bite structure according to the liquid level of the storage space 13, realizing intelligent control. The provision of the first elastic member 44 ensures the reliability and sensitivity of the bite structure. This mechanism design cleverly solves the problem of energy storage and release control of the energy storage component, and improves the degree of automation and efficiency of the device.

[0086] The design and interlocking structure of the push rod 147 and the float 1471 achieve an automatic control effect. When the liquid level in the storage space 13 changes, the float 1471 drives the push rod 147 to move up and down, thereby controlling the position of the interlocking ring 43. This design enables the device to automatically adjust the energy storage and release state according to actual needs. In practical applications, the energy storage component in this embodiment can be adjusted according to different working environments. For example, for high-viscosity liquids, the shape of the float 1471 can be adjusted to improve the sensitivity of liquid level sensing.

[0087] In some embodiments, a wind knife structure is provided on the first stirring blade 144, and the wind knife structure is connected to the cylinder 141 through a first switch valve structure, and the second control valve structure is connected to the storage space 13 through a second switch valve structure. When the liquid level in the storage space 13 is lower than a threshold value, the first switch valve structure connects the wind knife structure with the cylinder 141, otherwise the wind knife structure is blocked from the cylinder 141. When the air pressure in the storage space 13 is greater than a first predetermined value, the second switch valve structure blocks the second control valve structure from the storage space 13. When the air pressure in the storage space 13 is less than a second predetermined value, the second switch valve structure connects the second control valve structure with the storage space 13. The second predetermined value is less than the first predetermined value. In the present embodiment, the second predetermined value is slightly greater than the normal atmospheric pressure.

[0088] During the discharge process of the device, that is, when the liquid level decreases, the first switch valve structure opens, allowing the nitrogen in the cylinder 141 to enter the storage space 13 through the air knife structure, and using the gas to blow off the food sauce remaining on the side wall of the storage space 13, and fully transfer the food sauce in the storage space 13. At the same time, the second switch valve structure adjusts the state of the second control valve structure according to the change of the air pressure in the storage space 13 to maintain an appropriate working pressure.

[0089] In some embodiments, the first switch valve structure includes an exhaust duct 51 opened on the cylinder 141, and a first valve plate 52 capable of opening or closing the exhaust duct 51 is provided on the push rod 147. The exhaust duct 51 is used to connect the cylinder 141 and the wind knife structure to achieve gas discharge. The first valve plate 52 can open or close the exhaust duct 51 to control the flow of gas.

[0090] When the liquid level in the storage space 13 changes, the float 1471 will drive the push rod 147 to move up and down. The movement of the push rod 147 directly controls the switch state of the first valve plate 52, thereby realizing automatic control of the exhaust duct 51. When the liquid level decreases, the push rod 147 moves down, and the first valve plate 52 opens the exhaust duct 51, allowing gas to flow from the cylinder 141 to the wind knife structure, blowing off the residual dip on the side wall. When the liquid level rises, the push rod 147 moves up, and the first valve plate 52 closes the exhaust duct 51, stopping the gas circulation, that is, when there are more contents in the storage space 13, the exhaust duct 51 does not emit gas, thereby avoiding affecting the stirring effect.

[0091] In some embodiments, an annular exhaust groove 412 connected to the exhaust duct 51 is provided on the inner wall of the driven ring 41; the wind knife structure includes an air supply cavity 1441 provided on the first stirring blade 144, and a plurality of air supply holes 1442 connected to the air supply cavity 1441 are evenly distributed along the vertical direction on one side of the first stirring blade 144 close to the inner wall of the tank body 1; a cantilever 413 is connected between the driven ring 41 and the first stirring blade 144, and an air supply duct 4131 connecting the exhaust groove 412 and the air supply cavity 1441 is provided in the cantilever 413.

[0092] The annular exhaust groove 412 on the inner wall of the driven ring 41 is connected to the exhaust duct 51, providing an air flow channel for the wind knife structure. The air supply chamber 1441 on the first stirring blade 144 serves as the main body of the wind knife structure, and is used to store and distribute airflow. The multiple air supply holes 1442 of the first stirring blade 144 close to the inner wall of the tank body 1 are evenly distributed in the vertical direction and are connected to the air supply chamber 1441, which is used to evenly transport the airflow to the vicinity of the inner wall of the tank body 1. The cantilever 413 connects the driven ring 41 and the first stirring blade 144, providing a transmission channel for the airflow. The air supply duct 4131 in the cantilever 413 connects the exhaust groove 412 and the air supply chamber 1441, realizing the transmission of the airflow from the exhaust duct 51 to the air supply chamber 1441.

[0093] The exhaust duct 51 transmits the airflow to the air supply duct 4131 in the cantilever 413 through the annular exhaust groove 412, and then transmits the airflow to the air supply cavity 1441 on the first stirring blade 144 through the air supply duct 4131. Finally, the airflow is evenly sprayed near the inner wall of the tank body 1 through the evenly distributed air supply holes 1442, so that the food sauce is effectively blown off and the food sauce is prevented from remaining on the inner wall of the tank body 1.

[0094] This technical solution achieves effective transmission and uniform distribution of airflow by cleverly designing the connection between the wind knife structure and the cylinder 141. The design of the annular exhaust groove 412 ensures the uniform distribution of airflow on the driven ring 41, and the design of the cantilever 413 and the air supply duct 4131 achieves effective transmission of airflow from the cylinder 141 to the first stirring blade 144. The design of the air supply cavity 1441 and the uniformly distributed air supply holes 1442 on the first stirring blade 144 further ensures the uniform distribution of airflow in the tank body 1, effectively improving the stirring effect and anti-sedimentation effect.

[0095] In some embodiments, the second switch valve structure includes a valve seat 61, and a second valve plate 62 slidably connected to the valve seat 61, a follower portion 621 is provided on the second valve plate 62, an air pressure chamber 63 is opened in the valve seat 61, a slider 64 is sealed and slidably connected in the air pressure chamber 63, a first active portion 641 and a second active portion 642 cooperating with the follower portion 621 are provided on the slider 64, a second elastic member 65 is connected between the slider 64 and the valve seat 61, and the second elastic member 65 makes the slider 64 tend to move away from the valve seat 61.

[0096] The second switch valve structure of the present application realizes automatic control of the air pressure in the storage space 13 through the cooperation of the valve seat 61, the second valve plate 62, the slider 64 and the second elastic member 65. When the air pressure in the storage space 13 exceeds the first predetermined value, the air pressure in the storage space 13 pushes the slider 64 to compress the second elastic member 65, so that the first active part 641 of the slider 64 pushes the second valve plate to move upward to the position of closing the exhaust passage through the driven part 621, thereby preventing the gas in the cylinder 141 from leaking out. When the air pressure in the storage space 13 is lower than the second predetermined value, the second elastic member 65 pushes the slider 64 to move downward, so that the second active part 642 of the slider 64 pushes the second valve plate to move downward to the position of opening the exhaust passage through the driven part 621, thereby reconnecting the cylinder 141 with the storage space 13.

[0097] The method of use of the present invention is as follows:

[0098] In the initial state, the air pressure in the storage space 13 is less than the second predetermined value, and the second switch valve structure connects the second control valve structure and the storage space 13 .

[0099] When the device is loaded with the dipping sauce, the liquid level in the storage space 13 gradually rises, the float 1471 moves up and drives the push rod. The float 1471 drives the push rod 147 to move upward, and the bite structure is in the first state. Then, liquid nitrogen is introduced into the cylinder 141 through the liquid supply pipe 143. The liquid nitrogen absorbs the heat of the food dipping sauce and then vaporizes and expands. The nitrogen formed pushes the piston 142 to move upward. The linear motion of the piston 142 is converted into the rotational motion of the active ring 1411 through the motion conversion structure. The active ring 1411 drives the driven ring 41 and the first stirring blade 144 to rotate through the bite ring 43 to stir the dipping sauce in the storage space 13.

[0100] When the piston 142 reaches the top dead center position, the first control valve structure connects the cylinder 141 and the liquid supply pipe 143, and the second control valve structure connects the cylinder 141 and the storage space 13, and the gas in the cylinder 141 is discharged into the storage space 13. As the liquid nitrogen flows into the cylinder 141, the volume of the gas in the cylinder 141 decreases at low temperature, forming a negative pressure in the cylinder 141, and moves downward to the bottom dead center position under the joint action of the first elastic member 1421. At the bottom dead center position, in order to prevent excessive liquid nitrogen from flowing into the cylinder 141, the first control valve structure blocks the cylinder 141 and the liquid supply pipe 143, and the piston 142 returns to the starting point position under the elastic force of the second elastic member 1422. In this way, the piston 142 performs reciprocating linear motion, using the pressure of the liquid nitrogen gasification expansion to move and drive the first stirring blade 144 to rotate. In the process of gradual cooling, the air pressure in the storage space 13 gradually increases. When the air pressure in the storage space 13 exceeds the first predetermined value, the second switch valve structure blocks the second control valve structure and the storage space 13. At this time, the liquid nitrogen is stopped from being transported into the cylinder 141, and the air pressure in the cylinder 141 is substantially equal to the air pressure in the storage space 13.

[0101] When the device is ready to discharge, hot steam is introduced into the heating chamber 71 through the medium input interface 72, and the motor 32 drives the second stirring blade 31 to rotate, so that the food sauce is evenly heated. At the same time, the motor 32 drives the second stirring blade 31 to rotate, and the eddy current generated by the rotation will drive the first stirring blade 144 and the driven ring 41 to rotate along the first rotation direction. During this process, the spring 42 is gradually tightened, and because the bite structure restricts the driven ring 41 from rotating relative to the active ring 1411 along the second rotation direction, the energy stored in the spring 42 cannot be directly released.

[0102] When the device starts to discharge, the motor 32 is turned off and the discharge pipe 12 is opened. Under the action of the air pressure in the storage space 13, the food sauce is pressed out of the storage space 13. At this time, the air pressure in the storage space 13 is lower than the air pressure in the cylinder 141, but still greater than the second predetermined value. As the liquid level in the storage space 13 drops, when the buoyancy obtained by the float 1471 is less than the elastic force of the first elastic member 44, the bite structure changes from the first state to the second state, and the restriction on the driven ring 41 is released. At this time, the energy stored in the clockwork 42 drives the driven ring 41 to rotate in the second direction, thereby driving the first stirring blade to rotate. Further, the push rod 147 moves downward and drives the first valve plate 52 to open the exhaust duct 51. The high-pressure gas in the cylinder 141 flows to the wind knife structure and blows out from the air supply hole 1442 of the first stirring blade 144, blowing off the residual sauce on the side wall.

[0103] When the dipping sauce in the storage space 13 is emptied, the storage space 13 is connected to the outside, so that the air pressure in the storage space 13 is restored to atmospheric pressure, and the air pressure value is less than the second predetermined value. At this time, the second switch valve structure connects the second control valve structure and the storage space 13 to transfer or cache the next batch of dipping sauce.
