Description

Technical Field

[0001] This invention pertains to food machinery, specifically relating to a method for mixing and feeding fillings for hot pot. Background Technology

[0002] Hot pot filling, also known as "fish-wrapped meat," is typically made by mincing the meat of eel, shark, or freshwater fish, mixing it with sweet potato starch (starch), and then wrapping it around a filling of lean pork or shrimp to create a ball-shaped food.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] See Figures 1-11 A method for mixing and feeding hot pot filling includes a frame and a mixing pipe 50 located in the middle of the frame. The mixing pipe is connected to a coating discharge pipe 10, which serves as the outer coating of the hot pot filling, and a filling discharge pipe 30, which leads to the filling. The filling discharge pipe 30 has a filling discharge port 310 on its side for discharging the filling. The top of the filling discharge pipe 30 has an opening for the filling to enter. A filling regulating valve 40 is provided at the filling discharge port. The coating discharge pipe is provided with a coating inlet 110 and a coating outlet 120. A baffle 20 for adjusting the area of ​​the coating outlet 120 is provided at the coating outlet 120. The baffle 20 is driven to move by a baffle driving mechanism.

[0038] The specific steps are as follows:

[0039] (1) The upper part of the filling discharge pipe is provided with an opening. The filling entering through the opening is then fed into the middle of the mixing pipe after being adjusted by the filling extrusion regulating valve.

[0040] (2) In sync with step (1), the slurry input into the mixing pipe is introduced to cover the outside of the filling. The mixing pipe has a forming port at the bottom, and the filling is discharged through the forming port to form hot pot ingredients.

[0041] In this embodiment, the filling regulating valve includes an outer shell 410, which has a filling inlet 411 corresponding to the filling discharge port 310 and a filling extrusion port 412 for discharging filling. The outer shell has a movable valve stem 420, and the valve stem has a through hole 421 in the middle that connects the filling inlet and the filling extrusion port to form a filling extrusion passage. The valve stem 420 moves axially to control the size of the cross-section of the filling extrusion passage.

[0042] In this embodiment, the filling discharge port 310 in the filling regulating valve 40 is connected to the filling discharge pipe 310 to facilitate the filling to enter the filling regulating valve 40 after being discharged from the filling discharge pipe 30. There are two filling extrusion ports 412, mainly for the simultaneous production of two hot pot fillings. The number of filling extrusion ports 412 can be increased or decreased as needed.

[0043] The valve stem 420 can slide with the outer shell, and the connecting hole 421 can be used to control the diameter of the filling extrusion port 412. By moving the valve stem 420, the size of the connecting hole 421 and the filling extrusion port 412 can be controlled, thereby controlling the size of the filling extrusion passage cross section.

[0044] In embodiments of the present invention, when the position of the valve stem 420 needs to be adjusted, only the valve stem 420 needs to be moved. This can be achieved manually, or by the valve stem drive mechanism being an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. When using an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, the valve stem 40 can be fixedly connected to the telescopic end of the aforementioned mechanism. For manual operation, relevant buckles, scales, or limiting structures can be designed on the surface of the housing 30 to facilitate operator control.

[0045] In this embodiment, the size of the connecting hole 421 can be a single through hole, used to control the uniformity and size of the filling at the two filling extrusion ports. Alternatively, multiple connecting holes 421 can be designed according to the position and size of the filling extrusion port 412, and the size of the filling can be adjusted by staggering the position of the connecting holes 421 and the filling extrusion port 412.

[0046] In one embodiment of the present invention, as shown in the figure, an extension plate 422 is fixed to the inner end of the valve stem 420, and an adjusting screw 430 is hinged to the lower part of the outer shell. The adjusting screw is threadedly engaged with the extension plate. In this embodiment, the adjusting screw 430 can be hinged to the outer shell through a bearing. The adjusting screw 430 and the extension plate 422 are threadedly engaged to form a screw and nut mechanism. When adjustment is required, the valve stem 420 is moved by rotating the adjusting screw 430 to achieve adjustment.

[0047] In actual use, the valve stem 420 can be replaced as needed.

[0048] In one embodiment of the present invention, the filling discharge pipe 30 has a rotatable extrusion rod 320, the extrusion rod 320 is eccentrically arranged with the filling discharge pipe 30, there is a gap between the outer surface of the extrusion rod and the inner wall of the filling discharge pipe, and a lever 321 is fixed in the middle of the filling extrusion rod.

[0049] In this embodiment, the extrusion rod 320 is driven to rotate by a motor. In actual design, the extrusion rod 320 can also be driven to rotate by other transmission methods. The rotation of the extrusion rod 320 drives the radially arranged lever 321 to rotate. The lever 321 presses the filling material entering the gap at the top of the filling discharge pipe 30 and pushes it into the filling inlet 411 on the side of the filling discharge pipe 30.

[0050] In one embodiment of the present invention, an adjusting sleeve 330 located outside the extrusion rod is provided inside the filling discharge pipe. The side of the adjusting sleeve 330 has an adjusting through hole that corresponds to the filling discharge port. The opening of the adjusting sleeve 330 is the same as the opening at the top of the filling discharge pipe 30 to ensure that the filling enters the inner cavity of the adjusting sleeve 330.

[0051] The adjusting sleeve 330 is fixed to the filling discharge pipe 30 by a male-female groove fit. The gap is formed between the adjusting sleeve 330 and the extrusion rod 320, and a cover plate 331 is fixedly connected to the outer side of the filling discharge pipe to prevent the adjusting sleeve from falling out.

[0052] The above structure allows for easy replacement of the adjusting sleeve 330. Different adjusting sleeves 330 have different gaps with the lever 321 of the extrusion rod, thus allowing for adjustment of the extrusion efficiency and compactness of the filling by replacing the adjusting sleeve 330 as needed.

[0053] During operation, the filling discharge pipe is connected to a filling hopper 340 at the top. The filling hopper 340 contains a filling stirring paddle driven by a stirring motor. The bottom of the filling hopper is connected to the top of the filling discharge pipe 30. The filling that enters through the opening at the top of the filling discharge pipe 30 is discharged through the extrusion rod 320 to the filling regulating valve 40 on the side, and then discharged by the regulating valve 40.

[0054] In this embodiment, the slurry discharge port 120 of the slurry discharge pipe has two ports. The actual number can be designed according to the needs. The slurry output from the slurry discharge port 120 is used as the outer skin of the hot pot ingredients. Then, the filling is inserted into the inside and cut to form individual hot pot ingredients.

[0055] like Figure 6 As shown, in one embodiment of the present invention, the baffle driving mechanism includes a movable rod 210 hinged to the side of the baffle. The movable rod is fixed with an electric cylinder 220 at the rear. The electric cylinder drives the baffle 20 to move axially along the movable rod to change the area of ​​the adjusting sizing discharge port 120.

[0056] In actual design, the moving rod 210 can also be moved manually or by means of a screw nut, cylinder, etc., so as to move the baffle 20 of the discharge port area.

[0057] The baffle plate has an adjustment port for allowing the patina to pass through the patina discharge port. When the adjustment port is located between the two patina discharge ports 120, the discharge from the two discharge ports 120 is uniform and the discharge from the two patina discharge ports 120 is nearly identical. If the position of the baffle plate 20 is moved, the extrusion size of the two patina discharge ports 120 can be made different, thereby changing the particle size of the hot pot ingredients.

[0058] In addition, the two discharge ports 120 can be reduced by replacing the baffle plate 20 to achieve the effect of simultaneously adjusting the particle size of the hot pot ingredients.

[0059] In this embodiment, a push rod 130 extending into the patina discharge pipe is provided on the other side of the patina discharge port. The push rod of the patina discharge pipe is driven by a push rod driving device to reciprocate and squeeze the slurry in the patina discharge pipe out of the patina discharge port 120.

[0060] In the above embodiment, in order to better fix the position of the baffle 20, the patina discharge pipe is provided with a groove 121 for embedding the baffle at the patina discharge port 120, the baffle 20 can slide along the groove 121, and a sealing plate 122 is also fixedly connected to the outside of the patina discharge port to prevent the baffle 20 from falling out.

[0061] Each time the hot pot base is formed, the pusher rod 130 advances forward once, extruding the slurry from the slurry discharge port 120 once. The end of the pusher rod 130 is positioned facing the slurry discharge port, and one pusher rod 130 is provided for each slurry discharge port. Generally, all the pusher rods 130 operate synchronously.

[0062] In one embodiment of the present invention, the push rod driving device includes a push handle 131 that is laterally connected to the push rod 130. A swing fork 132 is inserted into the upper part of the push handle. The swing fork 132 is driven to swing back and forth by a swing shaft 133. A patina connecting rod 134 is eccentrically connected to the swing shaft. The lower part of the patina connecting rod has a slot 135. A patina crank 137 is eccentrically fixedly connected to the output end of a push motor 136. A limiting member extending into the slot 135 is provided on the outer end of the patina crank 137.

[0063] During operation, the pusher motor 136 drives the patina crank 137 to rotate. The outer end of the patina crank 137 has a limiting member that extends into the slot 135. The rotation of the crank 137 drives the patina connecting rod 134 to reciprocate in the vertical direction. The connecting rod 134 then pulls the swing shaft 133 to drive the reciprocating swing to drive the swing fork 132 to swing. The lower end of the swing fork has a long slot that engages with the push handle 131. The reciprocating swing of the swing fork 132 drives the pusher rod 130 to move back and forth.

[0064] In one embodiment of the present invention, a patina feed hopper 140 is fixedly connected above the patina feed inlet. The patina feed hopper is funnel-shaped with a larger top and a smaller bottom. The patina feed hopper has a spiral patina stirring blade driven by a stirring device inside, and the spiral inner diameter of the patina stirring blade gradually increases.

[0065] The patina material falling from the patina hopper 140 enters the patina feed inlet 110 and is pushed out from the patina discharge outlet 120 by the push rod 130. The push rod 130 and the patina discharge pipe have mutually cooperating guide sleeves to ensure the stability of the push rod 130 during the movement process.

[0066] The hot pot filling mixing and feeding mechanism includes a mixing pipe 50 and a pair of coating discharge pipes 10 connected to the mixing pipe. A pair of mixing chambers are provided inside the mixing pipe corresponding to the coating discharge pipes. An inner filling pipe 60 passes through the upper part of each mixing chamber. The inner filling pipe has an inner filling inlet 620 on its side and an inner filling outlet 630 at its bottom. The mixing pipe 50 has an inner filling guide pipe 510 facing the inner filling inlet. The inner filling guide pipe is connected to a filling extrusion port 412 via a pipeline and is used to form hot pot filling of different sizes. Each mixing chamber is connected to the coating discharge pipe 10, which is used to introduce the outer coating that forms the outer skin of the hot pot filling. The inner filling pipe has an inner filling inlet 620 on its side and an inner filling outlet 630 at its bottom. The inner filling inlet 620 is used to introduce the hot pot filling filling. The filling, after being mixed, is discharged from the lower part of the mixing chamber and then cut into fish balls in the cutting process.

[0067] If the present invention discloses or relates to mutually fixedly connected components or structural parts, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral molding process).

[0068] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this invention to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0069] Any component provided by this invention can be assembled from multiple individual components or can be a single component manufactured by a one-piece molding process.

[0070] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
