Description

Technical Field

[0001] This utility model relates to the field of equipment for producing pickled duck feet, specifically to a foaming tank for producing pickled duck feet. Background Technology

[0002] Pickled duck feet are a specially processed duck feet snack. The production process begins with selecting high-quality duck feet, then cleaning and removing impurities. Next, the duck feet are steamed to soften them. They are then mixed with seasonings and marinated to absorb the flavors and enhance their taste. During marinating, the duck feet are soaked in the seasoning solution to expand and soften.

[0003] Chinese Patent No. CN211322924U discloses a foaming tank for producing pickled duck feet, comprising a first tank body and a second tank body. Both ends of the first tank body are open, with the upper end designated as the upper port and the lower end as the lower port. Connecting portions are provided on both the upper and lower ports, and these connecting portions are connected to a sealing cap via a threaded structure. This invention facilitates the separate storage of different duck feet in the same foaming tank using a shared brine, effectively improving its flexibility. Furthermore, the modular design allows for the separate placement of duck feet and other ingredients within the same foaming tank, effectively preventing the ingredients from being carried into the tank during duck foot consumption, which would be inconvenient for consumption and affect the concentration of the ingredients in the foaming tank.

[0004] However, the above-disclosed technical solution has the following shortcomings: it lacks pressure on the duck feet, which cannot guarantee that all the duck feet are always below the surface of the seasoning liquid, which may affect the taste of some duck feet. In addition, it is inconvenient to remove duck feet from different areas. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art, such as the inability to ensure that duck feet are always below the surface of the seasoning liquid and the inconvenience of removing duck feet from different areas, by proposing a foaming tank for the production of soaked duck feet.

[0006] The technical solution of this utility model is: a foaming tank for producing pickled duck feet, the tank body having a detachable sealing cover at the bottom;

The tip of the inner basket has a vertical notch facing the central column.

[0010] And a pressure plate, located inside the inner basket, is slidably connected to the central column. The pressure plate presses down on the duck feet, so that the duck feet are below the liquid surface inside the tank.

[0011] Preferably, the tank is cylindrical, with a threaded ring on the top of the outer peripheral wall of the tank, and mating threads on the inner peripheral wall of the sealing cap and the outer peripheral wall of the threaded ring. A sealing gasket is provided on the inner top wall of the sealing cap, and the sealing gasket is pressed and adhered to the top end face of the tank.

[0012] Preferably, a frustum is provided on the inner wall of the bottom of the tank, with the frustum being smaller at the top and larger at the bottom. The bottom of the outer basket is located on the outer edge of the upper surface of the frustum, and a discharge gate is provided at the bottom of the tank.

[0013] Preferably, multiple grooves are provided on the outer peripheral wall of the central column, each groove is located in a notch of an inner basket, the pressure plate is fan-shaped, and a slider is provided at the tip of the fan shape, the slider cooperating with the groove.

[0014] Preferably, a counterweight is provided on the pressure plate, a groove is provided on the top of the counterweight, and a support rod is horizontally provided in the groove.

[0015] Preferably, a connecting rope is connected between the inner wall of the top of the sealing cap and the support rod, and the connecting rope is in a slack state.

[0016] Preferably, the inner peripheral wall of the outer basket contacts the outer peripheral wall of the inner basket, and the notch contacts the outer peripheral surface of the central column.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0018] 1. Under the action of counterweight and the weight of the pressure plate itself, the pressure plate presses on the duck feet in the inner basket, pressing them below the liquid surface, which can ensure that the duck feet are always below the liquid surface of the seasoning liquid, thus ensuring the processing effect of the duck feet.

[0019] 2. Rotate to open the sealing cover, pull the support rod to lift the corresponding pressure plate. If the pressure plate is too low, you can lift the counterweight and pressure plate with the connecting rope. After removing the pressure plate, you can continue to remove the inner basket, thus quickly removing the duck feet. After removing them, you can put them back into the tank.

The sealing gasket 6 is pressed and adhered to the top end face of the tank body 1 to achieve a seal.

[0028] The outer basket 8 is set on the inner wall of the bottom of the tank 1. The outer basket 8 is a hollow cylinder with openings at the top and bottom. The ingredients and various seasonings are located between the outer basket 8 and the tank 1. The inner circumferential wall of the outer basket 8 is in contact with the outer circumferential wall of the inner basket 9.

[0029] The central column 10 is vertically installed on the inner wall of the bottom of the tank body 1;

[0030] Multiple inner baskets 9 are provided. The inner baskets 9 are fan-shaped with a closed bottom and an open top. In an optional embodiment, the inner baskets 9 have a hollow structure. The inner baskets 9 are placed on the inner wall of the bottom of the tank body 1 and are located inside the outer basket 8. The end faces of multiple inner baskets 9 are in contact with each other and form a cylinder. The tip of the inner basket 9 has a vertical notch 12 facing the central column 10 and in contact with the outer peripheral surface of the central column 10.

[0031] And pressure plate 13, located inside inner basket 9, pressure plate 13 is slidably connected to central column 10, pressure plate 13 presses on duck feet, so that duck feet are below the liquid surface inside tank 1.

[0032] Example 2

[0033] like Figure 4As shown, this utility model proposes a foaming tank for producing duck feet. Compared with Embodiment 1, this embodiment details the discharge structure of the foaming liquid.

[0034] A frustum 7 is set on the inner wall of the bottom of the tank 1. The frustum 7 is smaller at the top and larger at the bottom. The bottom of the outer basket 8 is set on the outer edge of the upper surface of the frustum 7. A discharge gate 2 is set at the bottom of the tank 1. When it is necessary to discharge the ingredients and liquid between the outer basket 8 and the inner wall of the tank 1, the discharge gate 2 is opened, and the liquid can be quickly discharged through the discharge port under the guidance of the conical surface of the frustum 7.

[0035] Example 3

[0036] like Figures 3-4 As shown, this utility model proposes a foaming tank for producing duck feet. Compared with Embodiment 2, this embodiment details the relevant structure of the pressure plate 13.

[0037] Multiple grooves 11 are provided on the outer peripheral wall of the central column 10. Each groove 11 is located in the notch of an inner basket 9. The pressure plate 13 is fan-shaped, and a slider 19 is provided at the tip of the fan shape. The slider 19 cooperates with the groove 11. In an optional embodiment, four inner baskets 9, four pressure plates 13 and four grooves 11 are provided. Multiple arc-shaped grooves 18 are provided on the pressure plate 13 to facilitate rapid drainage.

[0038] A counterweight 14 is provided on the pressure plate 13, and a groove 15 is provided on the top of the counterweight 14. A support rod 16 is horizontally provided in the groove 15.

[0039] A connecting rope 17 is connected between the inner wall of the top of the sealing cover 3 and the support rod 16. The connecting rope 17 is in a slack state. After opening the sealing cover 3, since the pressure plate 13 and the counterweight 14 are both located inside the inner basket 9, if the pressure plate 13 is in a very low position, it is inconvenient to lift the counterweight 14 and the pressure plate 13 by lifting the support rod 16. At this time, the counterweight 14 and the pressure plate 13 can be easily lifted by pulling the connecting rope 17 upward, simplifying the operation.

[0040] In summary, when using this invention, the ingredients required for foaming are placed between the outer basket 8 and the inner wall of the tank 1. The liquid can flow smoothly through the outer basket 8 and the inner basket 9. Duck feet are placed in multiple inner baskets 9. The inner baskets 9 can hold duck feet requiring the same treatment, or duck feet with different treatment requirements. For example, duck feet in one inner basket 9 may require a shorter processing time, while those in another inner basket 9 may require a longer processing time. Alternatively, different types of duck feet requiring the same foaming treatment can be placed in different inner baskets 9. Then, the slider 19 is aligned with the slide groove 11, and the pressure plate 13 is installed. Under the action of the counterweight 14 and the weight of the pressure plate 13 itself, the pressure plate 13 presses down on the duck feet in the inner basket 9, pressing them below the liquid surface. This ensures that the duck feet are always below the liquid surface, thus guaranteeing the processing effect. Finally, the sealing cap 3 is placed on top for sealing. After the duck feet have finished soaking, rotate to open the sealing cover 3, pull the support rod 16 to lift the corresponding pressure plate 13. If the pressure plate 13 is too low, the counterweight 14 and the pressure plate 13 can be lifted by the connecting rope 17. After removing the pressure plate 13, the inner basket 9 can be removed, thus quickly removing the duck feet. After removal, they can be put back into the tank 1. Since the ingredients are located between the inner wall of the tank 1 and the outer basket 8, and the inner space of the outer basket 8 is only liquid, the inner basket 9 and the duck feet can be put back into the tank 1. It is very convenient to observe the state of the duck feet at different times.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
