Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and particularly to an intelligent filling system for the processing and production of beef tallow. Background Art

[0002] As an important animal fat, beef tallow is widely used in fields such as hot pot bases, baked foods, and seasonings. Its quality not only depends on raw materials and refining processes, but filling technology has a decisive impact on the texture stability, appearance aesthetics, and functional characteristics (such as layered structure) of the final product.

[0003] The melting point of beef tallow is 40 - 50°C. Generally, filling needs to be completed in its liquid state. Improper control of the temperature gradient during the cooling process is likely to cause the disordered growth of fat crystals (mainly β-crystalline form), leading to sanding (rough surface, granular feeling) and oil separation (seepage of liquid oil due to the breakage of the solid fat network) in beef tallow products.

[0004] With the surging market demand for functional beef tallow (such as multi-layer composite beef tallow) and customized-shaped beef tallow products, traditional filling equipment, such as gravity filling machines, can no longer meet market demands. It cans by directly injecting liquid beef tallow into packaging containers, and cannot achieve precise layering of heterogeneous beef tallow, easily causing interlayer penetration and resulting in flavor mixing. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent filling system for the processing and production of beef tallow to solve the above problems.

[0006] The present invention is achieved through the following technical solutions: An intelligent filling system for the processing and production of beef tallow includes a conveying module and a cooling module. The conveying module is used to store and convey beef tallow. The cooling module is used to cool and shape beef tallow. The cooling module includes a cooling platform and a refrigeration module. A mold is provided inside the cooling platform. The mold is used to receive the beef tallow output by the conveying module. The cooling platform is communicated with the refrigeration module. The refrigeration module is used to receive a pressurized fluid and adjust the temperature of the pressurized fluid. The cooling platform is used to change the contact position between the pressurized fluid and the mold. The pressurized fluid is used to reduce the temperature of the mold. An adjustment module is also provided inside the cooling platform. The adjustment module is used to push the mold to move; It further includes a control system. The control system is used to obtain the filling scheme input by the user, then obtain the initial temperature of the mold, obtain the required refrigeration temperature according to the initial temperature of the mold and the filling scheme, control the refrigeration module to work according to the refrigeration temperature, and at the same time obtain the initial relative position between the mold and the cooling platform, and synchronously control the cooling platform, the adjustment module, and the conveying module to work according to the initial relative position and the filling scheme.

[0007] Compared with the prior art, the present invention has the following advantages and beneficial effects: The design of the conveying module and the cooling module in the present invention utilizes the cooling platform to drive the mold to move, so as to realize the layered canning of butter. Compared with the prior art, the present invention can be applied to the alternating canning of multiple layers of heterogeneous butter, ensuring that different butters are at a suitable canning temperature. At the same time, it can also improve the accuracy of butter canning and facilitate the molding of customized butter products, reduce the occurrence of sanding and oil separation during the butter canning process, and thus improve the quality of the finished product. The design of the cooling platform in the present invention utilizes an adjustment module to drive the mold to move, and simultaneously uses a pressurized fluid to cool the mold to achieve precise canning of the butter. At the same time, the refrigeration module cools the pressurized fluid, so that the cooling platform can cool the butter entering the mold while driving the mold to move, accelerate the cooling rate of the butter entering the mold, and reduce the occurrence of interlayer penetration that affects the flavor of the finished product. At the same time, the cooling and pressurized fluid can quickly take away the heat around the mold during the process of driving the mold to move, thereby accelerating the cooling of the butter in the mold.

[0008] Further, the control system includes a controller, a temperature sensor and a plurality of distance measuring sensors; The temperature sensor is used to collect temperature information of the mold; The distance measuring sensors are used to collect distance information between the outer wall of the mold and the inner wall of the cooling platform; The controller is used to receive a canning scheme input by a user, wherein the canning scheme includes a butter canning method and a canning temperature, and then obtain the initial relative position of the mold according to the distance information, and calculate the moving direction and speed of the mold during the canning process according to the initial relative position and the canning method, and control the operation of the conveying module, the cooling platform and the adjustment module according to the moving direction and speed of the mold. The controller is also used to calculate the difference between the initial temperature information and the canning temperature according to the temperature information, calculate the refrigeration temperature of the butter during the canning process, and control the operation of the refrigeration module according to the refrigeration temperature.

[0009] Beneficial effects: This solution determines the movement trajectory and speed of the mold during the canning process by obtaining the temperature of the mold and its relative position to the cooling platform. Compared with the existing technology, this solution is not affected by the initial position of the mold, which helps to reduce the difficulty of operation.

[0010] Furthermore, the cooling platform includes a shell, and a plurality of nozzles are provided on the inner wall of the shell, and the nozzles are all connected to the refrigeration module. Solenoid valves are provided at the connection points between the nozzles and the refrigeration module, and the controller controls the operation of the solenoid valves and the nozzles according to the moving direction and speed of the mold.

[0011] Beneficial effects: Compared with the prior art, the solution of the housing with the nozzle can collect the pressurized fluid to a certain extent, avoid large-scale gas flow, and prevent heat exchange with the outside world, so as to prevent the temperature around the mold from rising and affecting the cooling effect.

[0012] Further, the conveying module includes a moving component, on which a number of filling valves are provided. The filling valves are all connected to storage tanks, and the storage tanks are all used to store butter. The moving component is used to drive the filling valves to move linearly on a horizontal plane, and the controller controls the working of the moving component and the filling valves according to the filling method, the moving direction and speed of the mold.

[0013] Beneficial effects: Compared with the prior art, the design of a number of filling valves and the like enables this solution to be applied to the synchronous filling of various types of butter. Different storage tanks can be used to store butter under different storage conditions, reducing the solidification of butter around the filling valves caused by poor storage conditions, which affects the filling effect, or the deterioration of butter, which affects the quality of the finished product, etc.

[0014] Further, the pressurized fluid is pressurized inert gas.

[0015] Beneficial effects: Compared with the prior art, this solution uses pressurized inert gas. During the process of pushing the mold to move, the inert gas can wrap around the mold to a certain extent, expel the oxygen around the butter, and reduce the reaction between the butter and oxygen, which affects the quality of the finished product.

[0016] Further, a cylinder lifting platform is provided on the inner bottom wall of the cooling platform, and the controller controls the working of the cylinder lifting platform according to the butter filling method.

[0017] Beneficial effects: This solution uses the cylinder lifting platform to continuously change the height of the mold during the butter filling process, so that the layer of butter being filled is always on the same horizontal plane as the nozzle, reducing the possibility of the temperature of the pressurized gas rising caused by heat convection, which affects the butter cooling effect.

[0018] Further, a number of electromagnets are provided on the top wall of the cylinder lifting platform, and permanent magnets are provided on the bottom wall of the mold. The controller controls the working of the electromagnets according to the filling method and the relative position between the mold and the cooling platform.

[0019] Beneficial effects: In this solution, the electromagnet and the permanent magnet repel each other, so as to push the mold to move upward away from the cooling platform. Compared with the prior art, this solution can make the pressurized fluid contact the bottom of the mold, enhancing its cooling effect. Further, the controller is further configured to construct a spatial coordinate system, obtain the spatial coordinates of several points on the inner sidewall of the cooling platform according to the size of the inner sidewall of the cooling platform, and then calculate the spatial coordinates of each position on the outer sidewall of the mold in combination with the initial distance information, obtain the spatial coordinates of several positions on the outer sidewall of the mold, and select the spatial coordinates located on the same horizontal plane to connect the head and tail to form an initial closed figure, calculate the initial area of the initial closed figure, and then obtain a real-time closed figure through the distance information in real time and calculate the real-time area in real time. Only when the real-time area is different from the initial area, it is determined that the mold is inclined relative to the horizontal plane, and the electromagnet is controlled to work.

[0020] Beneficial effects: In this solution, by synchronously comparing the real-time area and the initial area, it is judged whether the mold is inclined. When the mold is inclined, the electromagnet is timely activated to adsorb the mold, avoiding the mold from toppling and affecting the subsequent canning process.

[0021] Further, a plurality of openings are formed in the sidewall of the mold. The openings are all arranged inclined relative to the horizontal plane, and the height of the side of the opening close to the axis of the mold is higher than the side far from the axis of the mold. A clamping groove is formed on the side of the opening far from the axis of the mold. A baffle is slidably engaged with the opening through the clamping groove. The material of the baffle is an elastic material, and a spring is fixedly connected to the top wall of the baffle. The bottom wall of the baffle is detachably connected to the sidewall of the opening. The pressurized fluid is further used to push the baffle to deform and release the connection between the baffle and the sidewall of the opening.

[0022] Beneficial effects: In this solution, through the design of the opening, the pressurized fluid is introduced into the mold, so that the pressurized fluid can directly act on the surface of the butter, accelerating its solidification speed and slowing down the flow speed of the butter. Compared with the prior art, this solution helps to reduce the problem of interlayer penetration caused by the high-melting-point butter promoting the melting of the low-melting-point butter during the contact process between the high-melting-point butter and the low-melting-point butter.

[0023] Further, the controller is further configured to control the electromagnet to work according to the butter canning method. The material of the baffle is a magnetic material, and the electromagnet is further used to drive the baffle to move.

[0024] Beneficial effects: Compared with the prior art, this solution makes full use of the existing electromagnet structure, realizes the closing action of the opening through the electromagnet, reduces the operation steps of the operator, and improves the intelligent level of this solution.

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments and drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention has been in the actual R & D and use stage.

[0028] Embodiment 1 As Figures 1 to 4 shown, this embodiment includes a conveying module 2 and a cooling module 1. The conveying module 2 is used to store and convey butter. The conveying module 2 includes a frame 21. A moving component is provided on the frame 21. In this embodiment, the moving component is a split linear slide rail 23 with multiple sliders. A number of canning valves 22 are provided on the moving component, and the canning valves 22 are fixedly connected to different sliders by bolts. Each filling valve is communicated with a storage tank 24. The storage tanks 24 are all used to store butter. Electric heating wires are provided inside the side walls of the storage tanks 24. The electric heating wires are used to keep the butter in a fluid state continuously, and the butter stored in the storage tanks 24 is all different. The moving component is used to drive the canning valves 22 to perform linear motion on a horizontal plane.

[0029] The cooling module 1 is used to cool and shape butter. The cooling module 1 includes a cooling platform 11 and a refrigeration module. A mold 13 is provided inside the cooling platform 11. The mold 13 is used to receive the butter output by the conveying module 2. The refrigeration module is used to receive the pressurized fluid and adjust the temperature of the pressurized fluid. The cooling platform 11 is used to change the contact position between the pressurized fluid and the mold 13. The refrigeration module includes a refrigeration chamber 12. A thermoelectric cooler is fixedly connected inside the refrigeration chamber 12 by bolts. The cooling platform 11 includes a housing. A plurality of nozzles 15 are provided on the inner side wall of the housing. The nozzles 15 are fixedly connected to the inner side wall of the housing by bolts, and the nozzles 15 are all communicated with the output end of the refrigeration unit. Solenoid valves are provided at the communication positions between the nozzles 15 and the refrigeration chamber 12.

[0030] The pressurized fluid is used to reduce the temperature of the mold 13, and the pressurized fluid is pressurized inert gas. In this embodiment, the pressurized inert gas selected is nitrogen.

[0031] An adjustment module is further provided inside the cooling platform 11. The adjustment module includes a plurality of cylinders 18. The cylinders 18 are all fixedly connected to the inner side wall of the cooling platform 11 by bolts, and the cylinders 18 are evenly arranged along the axis of the cooling platform 11. The cylinders 18 are all used to push the mold 13 to move.

[0032] A control system is further included. The control system includes a controller, a temperature sensor, and a plurality of distance sensors. The controller is fixedly connected to the outer side wall of the housing by bolts. The temperature sensor and the distance sensors are all fixedly connected to the inner side wall of the housing by bolts, and the distance sensors are evenly arranged along the inner side wall of the housing. The distance sensors selected in this embodiment are infrared distance sensors, and the infrared rays emitted by the distance sensors are all perpendicular to the tangent of the inner side wall of the housing. The temperature sensor is used to collect the temperature information of the mold 13. The distance sensors are all used to collect the distance information between the outer side wall of the mold 13 and the inner side wall of the cooling platform 11.

[0033] The controller is used to receive the canning scheme input by the user. The canning scheme includes the butter canning method and the canning temperature. Then, the initial relative position of the mold 13 is obtained according to the distance information, and the moving direction and speed of the mold 13 during the canning process are calculated according to the initial relative position and the canning method. The split linear slide rail 23, the solenoid valve, and the nozzles 15 are controlled to work according to the moving direction and speed of the mold 13. The controller is further used to calculate the difference between the initial temperature information and the canning temperature according to the temperature information, calculate the refrigeration temperature of the butter during the canning process, and control the thermoelectric cooler to work according to the refrigeration temperature.

[0034] The specific implementation method is as follows: When using this solution, according to the process requirements of the butter to be canned, the corresponding type of butter is added to the storage tank 24.

[0035] For example, the canning requirement for a certain finished product butter is as follows: Use butter A and butter B for alternating canning. The melting point of butter A is higher than that of butter B, and the finished product butter presents a "flowing heart" state, with an outer shell of butter A and an inner filling of butter B. During use, add butter A and butter B to different groups of storage tanks 24 respectively, and start the heating wire to work according to their melting points to keep them in a fluid state.

[0036] Subsequently, place the mold 13 into the cooling platform 11, and connect the nitrogen generator or nitrogen storage tank to the refrigeration chamber 12. Then input the canning plan into the controller. The canning method recorded in the canning plan includes the types of butter for perfusion, canning sequence, canning speed, time points for alternating canning, canning area, etc. The recorded canning temperature is the temperature adjustment at different time points during the canning process.

[0037] During the canning process, the ranging sensor continuously works and obtains the distance information between the inner side wall of the upper shell at the corresponding position and the outer side wall of the mold 13 at the corresponding position. Since the size of the inner side wall of the shell is fixed, the installation position of the ranging sensor is fixed, and the detection direction of the ranging sensor is fixed, several points can be obtained by combining the above information with the distance information. Connecting these points into a smooth closed curve, this closed curve can, to a certain extent, reflect the shape, size of the mold 13, and the relative position relationship between the mold 13 and the shell, thereby performing basic positioning on the mold 13. Subsequently, the controller controls the operation of the split linear slide rail 23 according to the canning sequence and canning area in the canning plan. The split linear slide rail 23 moves the filling valve with the corresponding butter storage tank 24 to the central position of the shell.

[0038] During this process, the temperature sensor continuously collects the temperature information of the mold 13. The controller judges the cooling temperature required for the butter at this time point according to the temperature information and the canning temperature, and controls the operation of the semiconductor refrigeration chip to reduce the temperature of the pressurized nitrogen in the refrigeration chamber 12. Subsequently, according to the relative position between the mold 13 and the shell, the solenoid valve at the corresponding position is activated, so that the cooled pressurized nitrogen enters the shell through the corresponding nozzle 15, and when it acts on the mold 13, it pushes the mold 13 to move. During this process, the controller continuously performs basic positioning on the mold 13 according to the distance information to ensure that the moving position of the mold 13 is the same as the designed moving direction.

[0039] For example: During the process of canning a certain kind of butter, at a certain point in time, it is necessary to pour 0.5 cm of Butter A into the mold 13. The required cooling temperature of Butter A is A degrees Celsius. And at this time point, the mold 13 is located at the lower left corner of the housing. In the pouring method, pouring starts from the lower left corner of the mold 13 at this position. At this time, the controller moves the filling valve corresponding to Butter A to the center position of the housing through the split linear slide rail 23. Subsequently, the controller controls the solenoid valve corresponding to the nozzle 15 located on the left side below the housing to open. At the same time, the controller controls the cylinder 18 at the corresponding position to work. The cylinder 18 extends, pushing the mold 13 to move. At the same time, the pressurized nitrogen acts on the outer wall of the mold 13 synchronously with the output end of the cylinder 18 to cool the mold 13. When the controller calculates according to the distance information that the lower left corner of the mold 13 moves to be collinear with the center position of the housing, the controller controls the solenoid valve corresponding to the nozzle 15 at the center position on the right side of the housing to open, and again controls the cylinder 18 at the corresponding position to work. The mold 13 is pushed towards the center position of the housing by the cylinder 18 until the lower left corner of the housing is on the same straight line as the center of the housing, and at the same time, the pressurized nitrogen acts on the housing 13 to cool the housing 13. At this time, the controller controls the filling valve to open, and Butter A enters the mold 13 through the filling valve. The controller calculates the amount of butter entering the mold 13 in real time according to the valve port pressure head and the valve port flow area, etc. When the amount of butter at the corresponding position meets the requirements of the canning plan, the controller controls the solenoid valve and the cylinder 18 at the corresponding position to open again, changing the contact position between the mold 13 and the butter when the butter enters the mold 13.

[0040] After the canning and cooling of this layer of butter are completed, the controller controls the solenoid valve to work again, uses the cylinder 18 to push the mold 13 to the initial canning position, and uses the pressurized nitrogen to cool the mold 13. If the canned butter consists of two kinds of butter at this time, such as a closed frame formed by Butter A on the outermost side and Butter B inside the closed frame, at this time the controller repeats the above steps. After filling Butter A into the mold 13, the filling valve corresponding to Butter A is closed. Subsequently, the controller controls the split linear slide rail 23 to work again, driving the filling valve corresponding to Butter B to move to the initial canning position of this layer of Butter B. Subsequently, repeat the above steps to complete the canning of this layer of Butter B.

[0041] Repeat the above steps until the canning of this kind of butter is completed.

[0042] During the canning process, the cylinder 18 is used to push the mold 13 to move, so as to realize the canning of butter of different positions and categories. When the pressurized nitrogen acts on the surface of the mold 13, the temperature of the mold 13 is reduced, so as to achieve the effect of accelerating the cooling of the butter. At the same time, due to the rapid flow of the pressurized nitrogen in the shell, when facing the mold 13 with some non-streamlined designs, after the pressurized nitrogen contacts the mold 13, it is diverted by the mold 13 and converges on the other side of the mold 13, and entrains the surrounding gas due to inertia, accelerating the heat dissipation of the shell. Compared with the prior art, in this solution, the contact area between the low-temperature fluid and the shell is larger, which is beneficial to the heat dissipation of the shell and reduces the stratification of different types of triglycerides in the butter that may be caused by uneven cooling. And the solution using pressurized inert gas wraps the mold 13 during use, reducing the reaction between oxygen in the air and the butter, and preventing it from oxidizing and affecting the quality of the finished product.

[0043] Compared with the prior art, in this solution, the cylinder drives the mold 13 to move, so as to realize the stratified canning solution. Through stratified canning, this solution can carry out multi-layer heterogeneous butter alternate canning, effectively improving the flavor and diversity of the butter product. At the same time, during the movement, the butter is synchronously cooled by pressurized nitrogen.

[0044] Embodiment 2 The difference from the above embodiment is that a cylinder lifting platform 14 is provided on the inner bottom wall of the cooling platform 11. The cylinder lifting platform 14 is fixedly connected to the inner bottom wall of the shell by bolts. The cylinder lifting platform 14 is electrically connected to the controller, and the controller controls the operation of the cylinder lifting platform 14 according to the butter canning method. A plurality of electromagnets 16 are embedded in the top wall of the cylinder lifting platform 14, and permanent magnets 17 are embedded in the bottom wall of the mold 13. The electromagnets 16 are electrically connected to the controller, and the controller controls the operation of the electromagnets 16 according to the canning method and the relative position between the mold 13 and the cooling platform 11.

[0045] The controller is also used to construct a space coordinate system, and according to the dimensions of the inner side wall of the cooling platform 11, obtain the space coordinates of several points on the inner side wall of the cooling platform 11. Subsequently, combined with the initial distance information, calculate the space coordinates of each position on the outer side wall of the mold 13, obtain the space coordinates of several positions on the outer side wall of the mold 13, and select the space coordinates located on the same horizontal plane for end-to-end connection to form a smooth and closed curve. The figure divided by this curve is the initial closed figure, calculate the initial area of the initial closed figure, and then obtain the real-time closed figure through the distance information in real time, and calculate the real-time area in real time. Only when the real-time area is different from the initial area, it is determined that the mold 13 is inclined relative to the horizontal plane, and the electromagnet 16 is controlled to work.

[0046] The specific implementation method is as follows: When using this solution, during the canning process, the controller judges the time point of switching between layers during canning and the type of butter to be canned according to the canning method. For example, during the canning of the butter of the above brand, when the first layer of butter is canned and the second layer of butter is canned, when canning the sealing frame of the first type of butter in the second layer, since it is necessary to avoid the temperature of the first type of butter entering the mold 13 being too high and still being in a liquid state after contacting the first type of butter in the mold 13, and then diffusing into the inside of the sealing frame under the action of gravity, resulting in insufficient height and excessive width of the sealing frame, which affects the canning of the second type of butter in this layer and the canning of the next batch of butter. After the canning of one layer of butter is completed, the controller controls the cylinder lifting platform 14 to work, driving the mold 13 to move downward so that the layer of butter to be canned is on the same horizontal plane as the nozzle 15. Subsequently, the controller controls the cylinder 18 to work again to change the position of the mold 13 on the horizontal plane, thereby realizing the canning of the next layer of butter. This solution can effectively reduce the time from when the pressurized nitrogen leaves the nozzle 15 to when it contacts the mold 13 through the design of the cylinder lifting platform 14, thereby reducing the heat absorption of nitrogen during this process and affecting its cooling effect on the butter in the mold 13. Compared with the solution of setting the cylinder 18 on the cylinder lifting platform 14, since the cylinder 18 in this solution does not move with the mold 13, it can avoid the cylinder 18 blocking the pressurized nitrogen sprayed by the nozzle 15, thereby avoiding affecting the cooling effect of the pressurized nitrogen on the butter.

[0047] During the use process, the operator can judge whether to turn on the electromagnet 16 according to the size of the butter processed this time. When the size of the butter is too large or the bottom area of the butter is too large, and the cooling effect will significantly decrease with the solution of only cooling from the side of the mold 13, the solenoid valve can be turned on at this time. The electromagnet 16 generates the same magnetic field as the lower end of the permanent magnet 17, and it repels the permanent magnet 17 to push the mold 13 upward, so that the mold 13 floats on the top wall of the cylinder lifting platform 14. When the pressurized nitrogen acts on the outer wall of the mold 13 and is on the outer wall of the mold 13, part of the pressurized nitrogen can pass through the gap between the outer bottom wall of the mold 13 and the inner bottom wall of the housing, thereby cooling the bottom wall of the mold 13 and effectively improving the cooling effect of this solution.

[0048] And in the case of some butter designs with a small thickness of a single layer of butter, during the canning process, the controller keeps the magnetic field generated by the electromagnet 16 unchanged, and the magnitude of the force acting on the mold 13 remains unchanged. As the canning of the previous batch of butter in the mold 13 is completed, the weight of the mold 13 increases, thereby driving the mold 13 to move downward, so as to realize a slight adjustment of the position where the pressurized nitrogen sprayed by the nozzle 15 acts, which helps to accelerate the cooling speed of each layer in this type of butter.

[0049] Before canning, when the mold 13 is in the initial state, for the controller component space coordinate system, taking any central axis of the inner bottom wall of the shell as the X-axis, the center point of the inner bottom wall of the shell as the origin, any straight line on the inner bottom wall of the shell that is perpendicular to the X-axis and coincides with the origin as the Y-axis, and the axis of the shell as the Z-axis. Since the size of the shell is known, after the space coordinate system component is completed, several marking points are selected on the inner side wall of the shell. According to the size of the shell, the positional relationship between the marking points and the shell, and the distance relationship between the shell and the center point in the space coordinate system, etc., the space coordinates of the marking points on the inner side wall of the shell can be obtained. Since in the initial state, the bottom wall of the mold 13 is parallel to the inner bottom wall of the shell, after obtaining the distance information, based on the distance information and other data combined with the space coordinates of the marking points inside the shell, the space coordinates of several points on the mold 13 can be obtained. Select the space coordinates on the same horizontal plane of the mold 13 and connect them into a smooth curve, calculate the area of the closed figure formed by this curve, and take this area as the initial area.

[0050] During the subsequent canning process, the controller repeats the above steps, and the selected marking points are fixed. At the same time, the relative positional relationship between the selected horizontal plane and the marking points is fixed. Obtain the space coordinates of each point on the mold 13 on this horizontal plane during the canning process, connect them into a smooth closed curve, and obtain the real-time area of the figure enclosed by the curve in real time, and compare the real-time area with the initial area.

[0051] The controller can judge whether the mold 13 is a regular figure with the same area between the top wall and the bottom wall, the top wall and the bottom wall being parallel, and the side wall being perpendicular to the bottom wall according to the canning plan. When the mold 13 is a regular figure, the real-time area during the canning process should be consistent with the initial area. At this time, if the difference between the real-time area and the initial area during the canning process is greater than the preset value, the controller can determine that the mold 13 is in an inclined state.

[0052] Similarly, when the mold 13 is not a regular figure, the curve formed by the difference between the real-time area and the initial area should be relatively smooth. That is, when the difference between the two suddenly changes (such as the sudden increase or decrease value is greater than the set value), the controller can judge that the mold 13 is inclined.

[0053] At this time, the controller controls the electromagnet 16 to work to adsorb the mold 13.

[0054] Compared with the prior art, this solution can reduce the tilt of the mold 13 caused by the sudden drop of the cylinder lifting platform 14 or mechanical vibration, which affects the accuracy of the layered canning of butter or causes the mold 13 to fall, etc., and affects the quality of the finished product. At the same time, compared with the solution that directly uses distance information to select the positioning point and judge the state of the mold 13, this solution has higher flexibility and helps to reduce the continuous change of the positioning point caused by the continuous change of the position of the mold 13, which may cause the controller to misjudge. In addition, this solution uses the point on the shell as the marking point. Since the position and size of the shell are fixed, using it as a marking point can further avoid the controller misjudgment caused by the movement of the mold 13.

[0055] Example 3 The difference from the above embodiment lies in that: a plurality of openings 131 are provided on the side wall of the mold 13, the openings 131 are arranged inclined relative to the horizontal plane, and the height of the opening 131 close to the axis of the mold 13 is higher than that of the opening 131 away from the axis of the mold 13, a slot is provided on the side of the opening 131 away from the axis of the mold 13, the opening 131 is slidably fitted with a baffle 1311 through the slot, the baffle 1311 is made of elastic material, and a spring 1312 is bonded and fixed to the top wall of the baffle 1311, the bottom wall of the baffle 1311 is detachably connected to the side wall of the opening 131 by a buckle, and the inert fluid is also used to push the baffle to deform and release the connection between the baffle 1311 and the side wall of the opening 131.

[0056] The controller is also used to control the operation of the electromagnet 16 according to the butter canning method. The material of the baffle 1311 is a magnetic material, and the electromagnet 16 is also used to drive the baffle 1311 to move.

[0057] The specific implementation scheme is as follows: When using this scheme, when the melting point of the lower layer of butter is lower than that of the upper layer of butter, when the high melting point butter is directly poured onto the low melting point butter, the high melting point butter may cause the low melting point butter to melt, thereby causing interlayer penetration.

[0058] At this time, the operator first closes the filling valve, stops canning, and closes all the solenoid valves at the same time, while increasing the pressure of the pressurized nitrogen entering the refrigeration chamber 12, and then opens the solenoid valve to allow the pressurized nitrogen with higher pressure to impact the mold 13. Since the baffle 1311 is elastic, when the gas with higher pressure pushes the baffle 1311 to deform, the baffle 1311 is disengaged from the clamping position of the side wall of the opening 131, and the spring 1312 rebounds, driving the baffle 1311 to move, thereby opening the opening 131, and part of the pressurized nitrogen enters the mold 13 through the opening 131. Since the opening 131 is arranged inclined, the pressurized nitrogen entering the mold 13 moves upward.

[0059] During this process, the controller controls the positions of the solenoid valves according to the canning scheme, so that the solenoid valves corresponding to at least two opposite nozzles 15 are opened (such as the solenoid valves corresponding to the nozzle 15 directly on the right and the nozzle 15 directly on the left). After the pressurized nitrogen enters the mold 13, an upwardly inclined force is given to the butter entering the mold 13 to prevent the butter from continuing to move downward, thereby reducing the temperature of the butter. At the same time, since the pressurized nitrogen flows in the mold 13, it cools the surface of the butter that has been canned, reducing the probability of interlayer penetration between the upper and lower layers of butter.

[0060] When the canning of this layer of butter is completed, the controller closes the solenoid valve and controls the electromagnet 16 to work. The electromagnet 16 drives the baffle 1311 to move downward through magnetic force, stretching the spring 1312 until the baffle 1311 is engaged with the side wall of the opening 131 again, completing the restoration of the baffle 1311.

It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
