[0002] In the process of food dip production, according to different production process, it is often necessary to transfer or buffer the dip through a transfer device. However, the existing technology generally has a prominent problem in this link, that is, the lack of effective cooling and preservation function. The structure of these transfer devices is relatively simple, usually only composed of a conventional tank, which not only cannot cool the buffered dip in time and effectively, but also has poor air isolation, and the dip is easily oxidized by the oxygen in the air mixed in the tank, resulting in changes in the expected flavor characteristics of the dip, and unable to provide stable and high-quality taste experience for consumers.

[0044] When it is necessary to cool and preserve the dip in the storage space, liquid nitrogen can be introduced into the cylinder barrel. The liquid nitrogen absorbs heat during the gasification process, thereby cooling the dip. At the same time, the nitrogen gas after gasification enters the storage space, effectively reducing the oxygen content in the storage space, thereby slowing down the speed of oxidation of the dip by oxygen.

[0045] In addition, when the dip is cooled by liquid nitrogen, the volume expansion caused by the gasification of the liquid nitrogen can push the piston to reciprocate up and down. The up-and-down reciprocation of the piston is converted by the conversion structure into the rotary motion of the driving ring in the first rotary direction. The rotation of the driving ring further drives the first stirring blade to rotate, thereby stirring the dip in the storage space. In this way, the cooling efficiency is improved, and the dip can be further stirred during the cooling process, which helps to slow down the settlement of the dip.

[0046] When the temperature of the dip decreases, the viscosity of the dip increases, and the increase in viscosity helps to slow down the settlement speed of the high-density material in the dip, thereby reducing the negative impact of settlement on the taste of the food dip during long-term storage.

[0047] In summary, the food dip anti-settling transfer device provided by the application has the advantages of preventing dip settlement and high-efficiency preservation. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0059] The drawings are only used for illustrative purposes and should not be understood as limiting the patent; in order to better illustrate the embodiments, some components in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

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

[0061] To solve these problems mentioned in the background art, the applicant proposes a device as shown in the attached Figures 1-6The illustrated food dip anti-settling transfer device includes a tank body 1, a storage space 13 is arranged in the tank body 1, a feed pipe 11 and a discharge pipe 12 are arranged at the top and bottom of the tank body 1 respectively, and a first stirring mechanism and a second stirring mechanism are arranged in the tank body 1. The first stirring mechanism includes a vertically extending cylinder barrel 141, the cylinder barrel 141 is in heat transfer connection with the storage space 13, a piston 142 is sealingly and slidably connected in the cylinder barrel 141, the cylinder barrel 141 is connected with a liquid supply pipe 143 through a first control valve structure, and the cylinder barrel 141 is connected with the storage space 13 through a second control valve structure. A driving ring 1411 is rotatably connected to the cylinder barrel 141, a motion conversion structure is connected between the piston 142 and the driving ring 1411, and the motion conversion structure is used for converting the up-down reciprocating motion of the piston 142 into the rotary motion of the driving ring 1411 in a first rotary direction. The driving ring 1411 is connected with a first stirring blade 144 through an energy storage assembly, and the energy storage assembly stores energy when the first stirring blade 144 rotates relative to the driving ring 1411 in the first rotary direction. The second stirring mechanism includes a second stirring blade 31 and a motor 32 capable of driving the second stirring blade 31 to rotate in the first rotary direction. A heat insulation sleeve 74 is arranged outside the tank body 1, a heating cavity 71 is arranged between the heat insulation sleeve 74 and the tank body 1, and the heating cavity 71 is communicated with a medium input connector 74 and a medium output connector 73.

[0062] The tank body 1 is a container for storing and transferring food dip, which can be realized in 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 the cylinder barrel 141, the piston 142, the motion conversion structure and the first stirring blade 144.

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

[0064] The first stirring mechanism converts linear motion into rotary motion through the reciprocating motion of the piston 142 and the motion conversion structure, and drives the first stirring blade 144 to stir. At the same time, the design of the energy storage assembly allows energy storage and release, improving the continuity and efficiency of stirring. The second stirring mechanism provides additional stirring to further ensure the uniformity of the dip. In addition, the heat transfer connection between the cylinder barrel 141 and the storage space 13 can transfer the low temperature of liquid nitrogen to the food dip, which helps to maintain the appropriate temperature of the dip.

[0065] In use, first, the dip is introduced into the storage space 13 of the tank 1 through the feeding pipe 11, the liquid nitrogen is delivered into the cylinder 141 by the liquid supply pipe 143, the heat-conducting connection between the cylinder 141 and the storage space 13 allows heat to be transferred between them, 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 starts reciprocating up and down under the nitrogen gas pressure formed after the vaporization of the liquid nitrogen provided by the liquid supply pipe 143. The reciprocating motion of the piston 142 is converted into the rotary motion of the driving ring 1411 through the motion conversion structure. The driving ring 1411 drives the first stirring blade 144 to rotate and stirs the dip in the storage space 13. In other embodiments, the liquid supply pipe 143 can also deliver liquid carbon dioxide into 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 assembly stores part of the kinetic energy of the second stirring blade 31, facilitating subsequent discharging operation. At the same time, the heat insulation sleeve 74 and the heating chamber 71 structure outside the tank 1 can control the temperature of the food dip in the tank 1. By inputting or outputting heating medium into or out of the heating chamber 71 through the medium input joint 74 and the medium output joint 73, the temperature of the food dip in the tank 1 can be adjusted. When discharging is needed, the food dip is heated, which is beneficial to the discharge of the food dip. The heat insulation sleeve 74 can be made of foamed polyurethane or vacuum insulation material, and the thickness can be controlled between 20-50mm to provide good insulation effect.

[0067] In some embodiments, the piston 142 has a starting point position, a lower dead center position and an upper dead center position on its stroke; 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 center 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 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; the piston 142 is connected with an elastic assembly, which makes the piston 142 have a tendency to remain at the starting point position; the elastic assembly includes a first elastic member 1421 connected with the top end of the piston 142, and a second elastic member 1422 connected with the bottom end of the piston 142.

[0068] In this embodiment, the piston 142 movement is precisely controlled by setting the start point position, the bottom dead center position and the top dead center position on the stroke of the piston 142, and by controlling the switch state of the first control valve structure and the second control valve structure when the piston 142 is at different positions. The elastic assembly makes the piston 142 have a tendency to stay at the start point position, which helps 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 end and the bottom end of the piston 142, which can provide appropriate buffer and rebound force when the piston 142 moves up and down, further improving the smoothness and reliability of the piston 142 movement.

[0069] When the piston 142 is at the start point position, the liquid nitrogen is injected into the cylinder barrel 141 through the liquid supply pipe 143. Since the second control valve structure blocks the cylinder barrel 141 and the storage space 13, the nitrogen gas generated by the vaporization of the liquid nitrogen cannot be discharged to the storage space 13, thereby gradually pushing the piston 142 to move upward to the top dead center position. When the piston 142 reaches the top dead center position, the first control valve structure connects the cylinder barrel 141 and the liquid supply pipe 143, and the second control valve structure connects the cylinder barrel 141 and the storage space 13, so that the gas in the cylinder barrel 141 is discharged to the storage space 13. As the liquid nitrogen flows into the cylinder barrel 141, the gas in the cylinder barrel 141 reduces in volume at low temperature, forming a negative pressure in the cylinder barrel 141, and moving 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 avoid excessive liquid nitrogen flowing into the cylinder barrel 141, the first control valve structure blocks the cylinder barrel 141 and the liquid supply pipe 143, and the piston 142 returns to the start point position under the elastic force of the second elastic member 1422. In this way, the piston 142 reciprocates and moves by using the pressure generated by the vaporization of the liquid nitrogen.

[0070] In some embodiments, the first control valve structure includes a core rod 145 connected to the tank body 1 and the cylinder barrel 141, the core rod 145 is provided with a liquid inlet channel 1451, the side wall of the core rod 145 is provided with a liquid inlet hole 1452 in communication with the liquid inlet channel 1451, the outer side of the core rod 145 is sleeved with a plugging barrel 146, the plugging barrel 146 is provided with a driven shoulder 1461, and the piston 142 is provided with a first pushing shoulder 1423 and a second pushing shoulder 1424 matched with the driven shoulder 1461.

[0071] The first control valve structure is directly controlled by the movement of the piston 142, which achieves the effects of simple structure, accurate control and rapid response. The core rod 145 is connected with the tank 1 and the cylinder 141, and is internally provided with a liquid inlet channel 1451. A liquid inlet hole 1452 is formed in the side wall of the core rod 145 and is in communication with the liquid inlet channel 1451, for the flow of liquid. The blocking cylinder 146 is slidably sleeved outside the core rod 145 and is provided with a driven shoulder 1461 at the top, for controlling the opening and closing of the liquid inlet hole 1452. The piston 142 is provided with a first pushing shoulder 1423 and a second pushing shoulder 1424. When the piston 142 is not pushed by the first pushing shoulder 1423 or the second pushing shoulder 1424, the blocking cylinder 146 remains stationary with the core rod 145. The driven shoulder 1461 of the blocking cylinder 146 can be designed as an annular structure, with an outer diameter slightly smaller than the inner diameter of the cylinder 141, to ensure that it can freely slide in the cylinder 141. The first pushing shoulder 1423 and the second pushing shoulder 1424 on the piston 142 can be designed as an annular structure matching the driven shoulder 1461.

[0072] When the piston 142 rises, the first pushing shoulder 1423 pushes the blocking cylinder 146 to move upwards, opening the liquid inlet hole 1452. When the piston 142 descends, the second pushing shoulder 1424 pushes the blocking cylinder 146 to move downwards, closing 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 channel 21 formed on the cylinder 141, an exhaust channel 21 is provided with a check element 22, the cylinder 141 is slidably connected with a blocking plate 23, the blocking plate 23 is provided with a gas permeation hole 231, the blocking plate 23 is connected with a third elastic element 24, the third elastic element 24 makes the blocking plate 23 have a tendency to move to a position where the gas permeation hole 231 is misaligned with the exhaust channel 21; the piston 142 is provided with a pushing block 1425 matched with the blocking plate 23.

[0074] The exhaust channel 21 is formed on the cylinder 141, for discharging the nitrogen gas generated by the gasification of the liquid nitrogen in the cylinder 141. The exhaust channel 21 can be arranged at the upper part of the cylinder 141, to facilitate the discharge of gas. Discharging nitrogen gas into the storage space 13 can improve the protection effect of the food dip and enhance the fresh-keeping effect of the food dip; it can also increase the air pressure in the storage space 13, avoiding the liquid surface of the dip from shaking greatly during the movement of the device.

[0075] A check valve 22 is arranged in the exhaust passage 21, which mainly prevents the gas in the storage space from flowing back into the cylinder 141. The check valve 22 can adopt various forms, such as a one-way valve, a ball valve, or a spring valve, etc. A sealing plate 23 is slidably connected to the cylinder 141, which is used to control the opening and closing of the exhaust passage 21. The sealing plate 23 is made of a material with good sealing property and wear resistance, which can ensure good sealing effect when completely covering the exhaust passage 21. A gas hole 231 is arranged on the sealing plate 23, which allows gas to pass through when it is aligned with the exhaust passage 21 at a specific position. A third elastic member 24 is connected to the sealing plate 23, which keeps the sealing plate 23 in a position where the gas hole 231 is not aligned with the exhaust passage 21.

[0076] When the piston 142 rises, the push block 1425 pushes the sealing plate 23, so that the gas hole 231 is aligned with the exhaust passage 21, allowing gas to be discharged. At this time, the check valve 22 is opened, and the gas can be discharged from the exhaust passage 21. When the piston 142 descends, the third elastic member 24 makes the sealing plate 23 return to the initial position, closing the gas passage. At the same time, the check valve 22 is closed, preventing external gas from entering the cylinder 141. Not only can the discharge of gas be effectively controlled, but also external gas can be prevented from entering the cylinder 141, ensuring the normal operation of the device and the quality of the food dip.

[0077] In some embodiments, the motion conversion structure includes a guide groove 1426 arranged on the outer side wall of the piston 142, and a guide pin 1412 arranged on the inner side wall of the driving ring 1411 and slidably connected with the guide groove 1426; the guide groove 1426 includes a plurality of inclined segments and vertical segments alternately distributed along the circumference of the piston 142 and connected in sequence, the groove depth of the vertical segment gradually changes along the vertical direction, the groove depth of the bottom end of the vertical segment is greater than or equal to the groove depth of the inclined segment, and the groove depth of the top end of the vertical segment is less than the groove depth of the inclined segment; a spring member 1413 is connected between the guide pin 1412 and the driving ring 1411, which makes the guide pin 1412 have a tendency to approach the axis of the driving ring 1411.

[0078] The up-and-down reciprocating motion of the piston 142 is converted into the rotating motion of the driving ring 1411 through the above-mentioned arrangement. The guide groove 1426 is the core of this structure. The guide groove 1426 includes a plurality of inclined segments and vertical segments alternately distributed along the circumference of the piston 142 and connected in sequence. This design makes the guide pin 1412 move in the guide groove 1426 when the piston 142 moves up and down, thereby driving the driving ring 1411 to rotate. The inclined segment is mainly responsible for converting the vertical motion of the piston 142 into the rotating motion of the driving 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, and the bottom end groove depth is greater than or equal to the inclined section groove depth, and the top end groove depth is less than the inclined section groove depth. The radial position of the guide pin 1412 is adjusted by the change of the groove depth, so that the guide pin 1412 is more stably moved from the vertical section to the inclined section. By utilizing the characteristics of the mechanical structure, a simple and efficient motion conversion is realized. Through the special design of the guide groove 1426 and the use of the spring member 1413, the application not only solves the problem of converting the up-down reciprocating motion of the piston 142 into the rotary motion of the driving ring 1411, but also improves the conversion efficiency and stability.

[0080] Further, no matter whether the piston 142 moves upward or downward, the driving ring 1411 will keep rotating in the same direction. This is very important for the food dip anti-settling transfer device that needs continuous stirring, which can ensure the continuity and uniformity of the stirring process.

[0081] In some embodiments, the energy storage assembly includes a driven ring 41 rotationally connected with the cylinder barrel 141, and a spring 42 connecting the driving ring 1411 and the driven ring 41; the driving ring 1411 and the driven ring 41 are provided with an engagement structure having a first state and a second state; when the engagement structure is in the first state, the engagement structure limits the rotation of the driven ring 41 relative to the driving ring 1411 in the second rotation direction; when the engagement structure is in the second state, the engagement structure releases the rotation restriction of the driven ring 41; the engagement structure includes an engagement ring 43 movably sleeved on the driving ring 1411, an outer spline 1414 is arranged on the outer side wall of the driving ring 1411, an inner spline 431 matched with the outer spline 1414 is arranged on the inner side wall of the engagement ring 43, a ratchet 411 is arranged on the inner side wall of the driven ring 41, and a pawl 432 matched with the ratchet 411 is arranged on the outer side wall of the engagement ring 43; when the engagement structure is in the first state, the inner spline 431 is engaged with the outer spline 1414, and the pawl 432 is engaged with the ratchet 411; when the engagement 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 barrel 141, the bottom end of the push rod 147 extends into the storage space 13 and is connected with a floating ball 1471, and the top end of the push rod 147 abuts against the engagement ring 43; a first elastic member 44 is connected between the driving ring 1411 and the engagement ring 43, and the first elastic member 44 makes the engagement ring 43 have a tendency to move away from the driving ring 1411.

[0082] In some embodiments, the energy storage assembly includes a driven ring 41 and a spring 42, and the rotation of the driven ring 41 is controlled by a snap structure. The snap structure has two states, the first state limits the reverse rotation of the driven ring 41, and the second state removes the limitation. The snap structure is composed of a snap ring 43, an outer spline 1414, an inner spline 431, a ratchet 411, and a pawl 432, and different states are achieved by engagement or disengagement. The push rod 147 and the floating ball 1471 are used to sense the liquid level of the storage space 13 and control the position of the snap ring 43. The first elastic member 44 makes the snap ring 43 have a tendency to move away from the driving ring 1411.

[0083] When the device is loaded with material, the liquid level in the storage space 13 gradually rises, so that the snap 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 uniformly cooled, and the spring 42 is not tightened at this time.

[0084] When the device is discharged, the motor 32 drives the second stirring blade 31 to rotate, and the vortex generated by the rotation drives the driven ring 41 to rotate in the first rotation direction. In this process, the spring 42 is gradually tightened, and because the snap structure limits the rotation of the driven ring 41 relative to the driving ring 1411 in the second rotation direction, the energy stored by the spring 42 cannot be directly released. As the liquid level in the storage space 13 drops, the floating ball 1471 drops, causing the snap structure to change from the first state to the second state. At this time, the energy stored by the spring 42 drives the driven ring 41 to rotate in the first direction, thereby driving the first stirring mechanism to rotate and scraping off the food dip remaining on the side wall of the storage space 13, facilitating subsequent discharge.

[0085] This design achieves the control of energy storage and release of the energy storage assembly through the two states of the snap structure. When the snap structure is in the first state, the driven ring 41 is limited to rotate in one direction, and energy can be stored. When energy needs to be released, the snap structure switches to the second state, removing the limitation on the driven ring 41. The design of the push rod 147 and the floating ball 1471 enables the device to automatically adjust the state of the snap structure according to the liquid level of the storage space 13, achieving intelligent control. The setting of the first elastic member 44 ensures the reliability and sensitivity of the snap structure. This ingenious mechanism design solves the problem of energy storage and release control of the energy storage assembly, improving the automation and efficiency of the device.

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

[0087] In some embodiments, the first stirring blade 144 is provided with a wind knife structure, and the wind knife structure is connected with the cylinder 141 through a first switch valve structure, and the second control valve structure is connected with 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 and the cylinder 141, otherwise it blocks the wind knife structure and 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 and 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 and the storage space 13. The second predetermined value is less than the first predetermined value. In the embodiment, the second predetermined value is slightly greater than the regular atmospheric pressure.

[0088] In the process of discharging the device, that is, when the liquid level is lowered, the first switch valve structure is opened, allowing the nitrogen gas in the cylinder 141 to enter the storage space 13 through the wind knife structure, and the gas is used to blow off the food dip remaining on the side wall of the storage space 13, and the food dip in the storage space 13 is fully transferred. 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 of the storage space 13, so as to maintain the appropriate working pressure.

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

[0090] When the liquid level in the storage space 13 changes, the floating ball 1471 will drive the push rod 147 to move up and down. The movement of the push rod 147 directly controls the opening and closing state of the first valve plate 52, thereby achieving automatic control of the exhaust channel 51. When the liquid level decreases, the push rod 147 moves downward, the first valve plate 52 opens the exhaust channel 51, allowing gas to flow from the cylinder 141 to the air knife structure, and blowing the residual dip on the side wall. When the liquid level rises, the push rod 147 moves upward, the first valve plate 52 closes the exhaust channel 51, and when the storage space 13 contains more content, the exhaust channel 51 does not exhaust, thereby avoiding affecting the stirring effect.

[0091] In some embodiments, the inner side wall of the driven ring 41 is provided with an annular exhaust groove 412 which communicates with the exhaust channel 51; the air knife structure includes a air supply cavity 1441 provided on the first stirring blade 144, and the side of the first stirring blade 144 close to the inner wall of the tank 1 is uniformly provided with a plurality of air supply holes 1442 which communicate with the air supply cavity 1441; the suspension arm 413 is connected between the driven ring 41 and the first stirring blade 144, and the suspension arm 413 is provided with an air supply channel 4131 which communicates the exhaust groove 412 and the air supply cavity 1441.

[0092] The annular exhaust groove 412 of the inner side wall of the driven ring 41 communicates with the exhaust channel 51, providing an airflow passage for the air knife structure. The air supply cavity 1441 on the first stirring blade 144 serves as the main body of the air knife structure, for storing and distributing airflow. The plurality of air supply holes 1442 on the side of the first stirring blade 144 close to the inner wall of the tank 1 are uniformly distributed in the vertical direction and communicate with the air supply cavity 1441, for uniformly delivering airflow to the vicinity of the inner wall of the tank 1. The suspension arm 413 connects the driven ring 41 and the first stirring blade 144, providing a transmission passage for airflow. The air supply channel 4131 in the suspension arm 413 communicates the exhaust groove 412 and the air supply cavity 1441, achieving the transmission of airflow from the exhaust channel 51 to the air supply cavity 1441.

[0093] The exhaust channel 51 transmits airflow to the air supply channel 4131 in the suspension arm 413 through the annular exhaust groove 412, and then transmits airflow to the air supply cavity 1441 on the first stirring blade 144 through the air supply channel 4131. Finally, the airflow is uniformly sprayed to the vicinity of the inner wall of the tank 1 through the uniformly distributed air supply holes 1442, achieving effective blowing of the food dip and avoiding the food dip remaining on the inner wall of the tank 1.

[0094] The technical scheme realizes effective transmission and uniform distribution of the airflow by ingeniously designing the connection mode of the air knife structure and the cylinder 141. The design of the annular exhaust groove 412 ensures the uniform distribution of the airflow on the driven ring 41, and the design of the cantilever 413 and the air supply channel 4131 realizes effective transmission of the airflow from the cylinder 141 to the first stirring blade 144. The design of the air supply cavity 1441 and the uniform air supply holes 1442 on the first stirring blade 144 further ensures the uniform distribution of the airflow in the tank body 1, and effectively improves the stirring effect and the anti-settling effect.

[0095] In some embodiments, the second switch valve structure comprises a valve seat 61 and a second valve plate 62 in sliding connection with the valve seat 61, the second valve plate 62 being provided with a driven part 621, the valve seat 61 being provided with a gas pressure cavity 63, the gas pressure cavity 63 being in sealing sliding connection with a sliding block 64, the sliding block 64 being provided with a first driving part 641 and a second driving part 642 matched with the driven part 621, and the sliding block 64 being connected with the valve seat 61 through a second elastic member 65, the second elastic member 65 making the sliding block 64 have a tendency to move away from the valve seat 61.

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

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

[0098] In the initial state, the gas 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 with the storage space 13.

[0099] When the device is loaded with dip, the liquid level in the storage space 13 gradually rises, the floating ball 1471 moves up and drives the push rod 147 to move up, at this time the snap structure is in the first state. Then the liquid nitrogen is introduced into the cylinder 141 through the liquid supply pipe 143, and the nitrogen gas formed by the expansion of the liquid nitrogen after absorbing the heat of the food dip drives the piston 142 to move upward. The linear motion of the piston 142 is converted into the rotary motion of the driving ring 1411 through the motion conversion structure. The driving ring 1411 drives the driven ring 41 and the first stirring blade 144 to rotate through the snap ring 43, and the dip in the storage space 13 is stirred.

[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 gas in the cylinder 141 reduces in volume at low temperature, forming a negative pressure in the cylinder 141, and moving 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 avoid excessive liquid nitrogen 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, and moves by using the pressure of the expansion of the liquid nitrogen and drives the first stirring blade 144 to rotate. In the process of gradual cooling, the gas pressure in the storage space 13 gradually increases. When the gas 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 delivery of liquid nitrogen into the cylinder 141 is stopped, and the gas pressure in the cylinder 141 will be basically equal to the gas pressure in the storage space 13.

[0101] When the device is ready to discharge, hot steam is introduced into the heating cavity 71 through the medium input interface 72, and the motor 32 drives the second stirring blade 31 to rotate, so that the food dip is uniformly heated. At the same time, the motor 32 drives the second stirring blade 31 to rotate, and the vortex generated by the rotation drives the first stirring blade 144 and the driven ring 41 to rotate in the first rotation direction. In this process, the spring 42 is gradually tightened, and because the snap structure restricts the driven ring 41 from rotating in the second rotation direction relative to the driving ring 1411, 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 dip 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 is still greater than the second predetermined value. As the liquid level in the storage space 13 drops, when the buoyancy obtained by the floating ball 1471 is less than the elastic force of the first elastic member 44, the engagement structure changes from the first state to the second state, releasing the restriction on the driven ring 41. At this time, the energy stored in the spring 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, driving the first valve plate 52 to open the air discharge channel 51, and the high-pressure gas in the cylinder 141 flows to the air knife structure, blowing out from the air supply hole 1442 of the first stirring blade 144, and blowing off the residual dip on the side wall.

[0103] When the dip in the storage space 13 is discharged, the storage space 13 is connected with the outside, so that the air pressure in the storage space 13 returns 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 with the storage space 13, so as to transfer or buffer the next batch of dip.

Based on the above description, other different forms of changes or modifications can be made by those skilled in the art. It is not necessary or possible to exhaust all the embodiments.
