Description

Technical Field

[0001] This utility model relates to the field of soybean product technology, and in particular to an extrusion device for making dried soybeans. Background Technology

[0002] Dried tofu, also known as tofu skin, is a food made from soybeans and is widely used in the food culture of Asia, especially China, Japan and Korea. The history of dried tofu can be traced back to the Han Dynasty, and it can still be found in various Chinese cuisines. The production process of dried tofu mainly includes soaking soybeans, grinding them into a paste, boiling the paste, coagulating, pressing and drying. The equipment and technology in each step are key to achieving high-quality dried tofu.

[0003] A search revealed Chinese patent publication number CN217073477U, which discloses a bean curd extrusion device. The device includes an extrusion groove, a pressure plate whose shape matches the extrusion groove, and an extrusion rod at the upper end of the pressure plate. A pneumatic cylinder is located at the other end of the extrusion rod, and the outer wall of the pneumatic cylinder has an installation groove. The installation groove is connected to a support frame, and an auxiliary locking block is provided on the outer wall of the installation groove. The support frame is locked to the pneumatic cylinder via the installation groove and the auxiliary locking block. The pressure plate is slidably and vertically connected to the extrusion groove via the pneumatic cylinder, the extrusion rod, and guide beads. In this bean curd extrusion device, the inner wall of the extrusion groove is provided with a pressure plate, and guide beads are provided on both sides of the pressure plate. Furthermore, the shape of the pressure plate matches the shape of the extrusion groove.

[0004] However, in actual use, it was found that residual water stains on the pressing plate may breed bacteria, thereby increasing food safety risks and causing the dried bean curd to be contaminated before consumption, affecting its flavor and quality. Utility Model Content

[0005] The purpose of this invention is to solve the problem that residual water stains on the pressure plate in the prior art may breed bacteria, and to propose an extrusion device for making dried bean curd.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figure 1 - Figure 4 An extrusion device for making dried bean curd includes a platform 1, a limiting frame 2 fixedly connected to the platform 1, the limiting frame 2 forming an extrusion cavity, and a through hole 15 is also provided on the limiting frame 2 for discharging the bean juice after extrusion.

[0026] A support frame 5 is fixedly connected to the platform 1. An installation box 4 is fixedly connected to the outer wall of the support frame 5. An extension plate 9 is slidably connected to the installation box 4. A lifting rod 6 is slidably connected to the support frame 5, and the top of the lifting rod 6 is fixedly connected to the extension plate 9. An extrusion plate 7 is provided at the bottom of the lifting rod 6. The limiting frame 2 corresponds to the extrusion plate 7. When the extrusion plate 7 descends, it can move against the inner wall of the limiting frame 2.

[0027] The principle is to lay gauze in the extrusion cavity formed by the limiting frame 2, then lay the solidified tofu on the gauze, and then repeat the process of laying gauze and laying the solidified tofu on another layer of gauze to separate the layers. The lifting rod 6 drives the extrusion plate 7 to move toward the cavity of the limiting frame 2 and apply pressure, thereby removing excess water from the tofu and allowing the water to be discharged from the through hole 15, thus forming dried tofu.

[0028] After the dried bean curd is formed, the lifting rod 6 drives the extrusion plate 7 to reset, and then the formed dried bean curd is taken out. In order to facilitate the cleaning of water stains remaining at the bottom of the extrusion plate 7, two sets of symmetrical spray plates 3 are set on the platform 1, and the output end of the spray plate 3 faces the bottom of the extrusion plate 7. The spray plate 3 can rinse the water stains at the bottom of the extrusion plate 7, thereby effectively removing dirt and bacteria, reducing food safety risks, avoiding affecting the flavor of the dried bean curd in subsequent production, and ensuring that each batch of dried bean curd has a consistent taste.

[0029] A slide groove is provided on the mounting box 4, and a lead screw 8 is rotatably connected in the slide groove. An extension plate 9 is threadedly connected to the lead screw 8 and fits against the inner wall of the slide groove. A motor 10 is fixedly connected to the platform 1, and the lead screw 8 is fixedly connected to the output end of the motor 10. When the motor 10 rotates, it can drive the lead screw 8 to rotate synchronously, thereby causing the extension plate 9 to drive the lifting rod 6 to move back and forth.

[0030] To facilitate the supply of water to the spray plate 3, a pressure boosting cylinder 11 is fixedly connected to the outer wall of the mounting box 4. A pressure boosting rod 12 is slidably connected to the pressure boosting cylinder 11. One end of the pressure boosting rod 12 is fixedly connected to the extension plate 9, and the other end of the pressure boosting rod 12 is equipped with a piston 13, which is in contact with the inner wall of the pressure boosting cylinder 11. When the extension plate 9 moves the lifting rod 6 toward the cavity of the limiting frame 2, it can drive the extrusion plate 7 to move synchronously, thereby causing the extension plate 9 to move the pressure boosting rod 12. This causes the piston 13 at the bottom of the pressure boosting rod 12 to extrude gas into the cavity of the pressure boosting cylinder 11. A liquid storage tank 14 is fixedly connected to the platform 1. The device 1 is equipped with an air inlet pipe and an air outlet pipe, both of which are equipped with one-way valves. The air outlet pipe is connected to the liquid storage tank 14. The liquid storage tank 14 is connected to the spray plate 3 through the liquid outlet pipe 16, which delivers the gas to the liquid storage tank 14. The liquid storage tank 14 is equipped with a sealing cover. By opening the sealing cover, clean water can be filled into the tank. The sealing cover is then locked to seal the tank 14. When the piston 13 descends, it can deliver the air in the booster cylinder 11 into the liquid storage tank 14, which pressurizes the tank. When the piston 13 rises, the air in the booster cylinder 11 is replenished.

[0031] To facilitate the delivery of water from the storage tank 14, a control valve 17 is installed on the outlet pipe 16. When the squeezing plate 7 is reset and abuts against the bottom of the support frame 5, the control valve 17 can be turned on to deliver water from the storage tank 14 to the spray plate 3, thereby rinsing the water stains at the bottom of the squeezing plate 7. After rinsing is completed, the valve of the control valve 17 can be closed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
