DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0029] Example 1

[0030] refer to Figure 1 and Figure 2 The present embodiment provides a tofu pressing device, including a pressing frame 10, a pressing drive 20 and a pressing mold 30, wherein the pressing frame 10 is used to provide support for the pressing mold 30, and the pressing drive 20 provides a pressing force for the pressing mold 30 to dehydrate the tofu in the pressing mold 30 to complete the tofu pressing, and the operation is simple.

[0031] Specifically, the pressing mold 30 includes a pressing bottom plate 31, a pressing frame 32 and a pressing top plate 33. The pressing frame 32 is a sealed structure on all sides, which is used to surround the overall shape of the tofu after pressing. The size of the pressing frame 32 is selected according to the needs. The size of the pressing bottom plate 31 is not less than the size of the pressing frame 32. The shape of the pressing bottom plate 31 can be selected as a rectangle or a circle or a structure similar to the pressing frame 32, preferably a rectangular structure, so that when the pressing frame 32 is placed on the pressing bottom plate 31, the surrounding side of the pressing bottom plate 31 is located on the outside of the pressing frame 32. Therefore, when facing different sizes of pressing needs, it is only necessary to select pressing frames 32 of different sizes and shapes and matching pressing top plates 33 according to the needs. The operation is convenient and quick, saving time and effort while reducing equipment costs.

[0032] The pressing top plate 33 matches the pressing frame 32. When the tofu is pressed, the pressing frame 32 is placed on the pressing bottom plate 31 to form a pressing space in the pressing frame 32. The material is then injected into the pressing space, and the pressing top plate 33 is extended into the pressing frame 32. The pressing drive 20 pushes the pressing top plate 33 to compress the height of the pressing space, thereby completing the pressing of the tofu and obtaining a tofu whole that matches the pressing frame 32.

[0033] After the pressing is completed, you can choose to remove the pressing top plate 33 first, and then lift the pressing frame 32 to complete the demoulding; you can also choose to keep the pressing top plate 33 in place and then lift the pressing frame 32 to separate it from the tofu and then remove the pressing top plate 33. This method makes it convenient and quick to demould the tofu, completes rapid demoulding, and further improves work efficiency.

[0034] Further description, the pressing frame 10 includes a vertical support 11, a transverse support 12 and a bottom plate support 13, wherein the number of the vertical supports 11 is two, and the two vertical supports 11 are arranged at the left and right ends of the transverse support 12, and the bottom plate support 13 is arranged below the transverse support 12, and at the same time, the opposite sides of the bottom plate support 13 are connected to the corresponding vertical supports 11. By setting the bottom plate support 13, a stable and reliable support is provided for the pressing bottom plate 31, and by setting the transverse support 12, a fulcrum is provided for the pressing drive 20, and the pressing mold 30 is placed between the transverse support 12 and the bottom plate support 13, and the pressing drive 20 is arranged between the transverse support 12 and the pressing top plate 33.

[0035] In order to ensure that the pressing bottom plate 31 does not slide during use to affect the pressing effect, the pressing bottom plate 31 is connected to the bottom plate support 13 .

[0036] Therefore, in actual use, the pressing drive 20 drives the pressing top plate 33 to move vertically up and down along the inner wall of the pressing frame 32 by rising and falling. The pressing drive 20 can be optionally hydraulically driven or pneumatically driven, and the top of the pressing drive 20 can also be optionally connected to the lateral support 12 for easy operation.

[0037] In order to facilitate the placement and removal of the pressing mold 30 , the pressing frame 10 further includes a bottom support 14 to increase the height between the pressing mold 30 and the ground.

[0038] At the same time, in order to increase the structural strength of the pressing frame 10, the pressing frame 10 also includes a triangular support 15 and a reinforcing support 16. The number of triangular supports 15 is two, and the two triangular supports 15 are installed between the lower end surface of the lateral support 12 and the side end surface of the corresponding vertical support 11, so as to increase the stability and reliability of the connection position between the lateral support 12 and the vertical support 11.

[0039] There are four reinforcing supports 16, and both ends of the four reinforcing supports 16 are connected between the vertical support 11 and the bottom plate support 13, so as to increase the stability and reliability of the connection position between the vertical support 11 and the bottom plate support 13, thereby meeting the pressing force applied during the tofu pressing process.

[0040] The vertical support 11 and the horizontal support 12 may be I-beams, the reinforcing support 16 may be angle steels, and the bottom plate support 13 and the bottom support 14 may be square steels.

[0041] Further explanation: In order to avoid the small area of ​​direct contact between the pressing drive 20 and the pressing top plate 33 during the pressing process, which may easily cause damage to the pressing top plate 33, it is preferred that the bottom of the pressing drive 20 contacts the pressing top plate 33 through a pad 70, thereby increasing the actual service life, reducing maintenance costs, and meeting actual production needs.

[0042] During the pressing process, it is usually necessary to maintain the pressure for a set time. In order to avoid occupying the site, centralized stacking can be carried out. Therefore, movable wheels 60 are arranged at the bottom of the bottom support 14 to facilitate movement. Four movable wheels 60 are arranged, two of which can be universal wheels for easy steering, thereby further improving the pressing efficiency.

[0044] refer to Figure 1 to Figure 4 Based on the tofu pressing device provided in Example 1, in the tofu pressing device provided in this embodiment, a plurality of water outlet holes 40 are opened on the side of the pressing frame 32, and the number of the water outlet holes 40 can be selected to be three. The three water outlet holes 40 are arranged at equal intervals along the length direction of the side of the pressing frame 32, so as to facilitate the smooth discharge of water in the pressing space during the pressing process, thereby improving the tofu pressing quality.

[0045] Further explanation, a plurality of reserved slits 50 are provided at the top of the pressed top plate 33. The plurality of reserved slits 50 can be spaced apart in the same direction, or can be spaced apart in the transverse direction and the vertical direction respectively. The spaced apart slits 50 are spaced apart at equal intervals in the vertical direction as an example for explanation.

[0046] To further explain, a plurality of cross seams 51 are provided at the bottom of the pressed top plate 33, and the plurality of cross seams 51 are arranged in a row, such as a circular array or a rectangular array, preferably a matrix array. At this time, the spacing between two adjacent cross seams 51 on the left and right is the same, and the spacing between two adjacent cross seams 51 on the top and bottom is the same, thereby forming an array of cross protrusions on the top of the pressed tofu, which facilitates uniform cutting along the cross protrusions when the tofu is cut into pieces later.

[0047] Further explanation, in order to increase the structural strength of the pressing frame 32, a reinforcement member 34 is selected to be set at the top corner position of the outside of the pressing frame 32. The pressing frame 32 is illustrated by taking a rectangle as an example. The reinforcement member 34 is an L-shaped structure connected to the four right-angle positions of the pressing frame 32 to enhance the reliability of the pressing frame 32.
