Description

Technical Field

[0001] This utility model relates to the field of agricultural and sideline product processing technology, specifically to a sweet potato starch extraction device. Background Technology

[0002] One method of sweet potato starch extraction involves crushing the sweet potatoes and continuously rinsing the residue in a filter cloth to mix the starch with water and remove it.

[0003] Chinese patent document CN212941739U discloses a device comprising a frame, a material hopper, a cylinder, a core tube, and a filter bag. The frame is fixed on the material hopper, the cylinder body is fixed on the frame, the filter bag is wrapped around the core tube, and a space for sweet potato residue is formed between the filter bag and the core tube. A screw is rotatably connected to the push rod of the cylinder, and the top of the frame has a threaded hole that mates with the screw. Several winding reels are rotatably connected to the frame, and the winding reels are connected to the frame by a spring. A pull rope is wound on the winding reel, one end of which is fixedly connected to the winding reel, and the other end of which is fixed to the upper end of the core tube.

[0004] However, in the above scheme, the pull rope is wound around the filter bag by the action of the spring to tighten and squeeze the sweet potato residue in the filter bag. But when in use, because the spring tension and the stretching length are matched, the tension at the front end of the pull rope is less than the tension at the back end, making it difficult to ensure uniform stress on the filter bag and affecting the starch extraction effect.

[0032] Example 1

[0033] like Figure 1-5 As shown, the present invention proposes a sweet potato starch extraction device, which includes a barrel 1, a valve 2, and a lifting assembly;

[0034] The middle part of the barrel 1 has a cavity with an opening at the top, and the inner side of the cavity of the barrel 1 is provided with a filter component for holding and filtering sweet potato residue in use.

[0035] The lifting assembly is located on the side of the barrel 1 and extends toward the middle of the barrel 1. At the top of the lifting assembly and above the barrel 1, there is a spinning assembly extending toward the inside of the filter assembly.

[0036] Valve 2 is installed at the bottom of barrel 1 and is connected to barrel 1.

[0037] In this embodiment, sweet potato residue is placed in a filter assembly, and clean water is added to the inside of the barrel 1, allowing the water to pass through the filter assembly and contact the sweet potato residue. The lifting assembly moves the spinning assembly downward into the filter assembly, and the spinning assembly is activated, causing the spinning assembly to move the sweet potato residue and water towards the upper inner part of the filter assembly, ensuring full contact between the sweet potato residue and water and fully dissolving the starch in the sweet potato residue in the water. The filtered starch water is then discharged through valve 2. Simultaneously, by reversing the spinning assembly, the sweet potato residue is moved towards the bottom inner part of the filter assembly, causing the spinning assembly to squeeze the sweet potato residue, resulting in more thorough starch extraction and higher starch extraction efficiency.

[0038] Example 2

[0039] like Figure 5As shown, the present invention proposes a sweet potato starch extraction device. The difference between this embodiment and the first embodiment is that the filtration assembly includes a filter bag 13 and a support basket 14.

[0040] The support basket 14 is installed in the middle of the barrel 1;

[0041] The filter bag 13 is placed inside the support basket 14 and its top flange is sleeved on the top outer side of the support basket 14.

[0042] In an optional embodiment, a holding basket 3 is provided on the inner side of the filter bag 13. The top of the holding basket 3 is wrapped around the outer side of the top of the filter bag 13 and connected to the lifting assembly. It is used to fit the filter bag 13 to the inner side of the support basket 14 during use and to separate the filter bag 13 from the spinning assembly to avoid damage to the filter bag 13 by the spinning assembly.

[0043] In an optional embodiment, a handle 5 is provided at the top of the basket 3 and on the side of the slider 11 for easy movement and rotation of the basket 3 during use.

[0044] In this embodiment, the support basket 14 is connected to the barrel 1, so that the filter bag 13 is installed in the barrel 1 to filter the sweet potato residue. The holding basket 3 is installed inside the filter bag 13 and connected to the lifting component to ensure that the spinning component does not damage the filter bag 13 during the movement. The sweet potato residue is placed inside the holding basket 3 for pressurization. At the same time, when the lifting component moves the spinning component upward, the holding basket 3 is separated from the filter bag 13, so that the sweet potato residue is separated from the filter bag 13, which facilitates the discharge of the sweet potato residue.

[0045] Example 3

[0046] like Figure 1-2 As shown, the present invention proposes a sweet potato starch extraction device. The difference between this embodiment and the first embodiment is that the lifting assembly includes a mounting plate 7 and a telescopic rod 10.

[0047] The telescopic rod 10 is rotatably mounted on the side of the barrel 1 and arranged facing upwards towards the barrel 1. The telescopic rod 10 is one of a cylinder, a hydraulic cylinder, and an electric telescopic rod.

[0048] Mounting plate 7 is installed at the top of telescopic rod 10 and extends to the top of the other side of barrel 1.

[0049] In an optional embodiment, a notch is provided at one end of the mounting plate 7, and a hinge bolt 9 is provided at the top of the barrel 1. The hinge bolt 9 is located inside the notch of the mounting plate 7 and is connected to the mounting plate 7. It is used to fix the end of the mounting plate 7 during use and to prevent the spinning assembly from shaking during use.

[0050] In an optional embodiment, sliders 11 are provided on both sides of the top of the basket 3, and arc-shaped grooves 12 are provided on the bottom of the mounting plate 7 and on both sides of the barrel 1. When the mounting plate 7 and the basket 3 are installed together, the sliders 11 are accommodated in the arc-shaped grooves 12, which are used to connect the basket 3 and the mounting plate 7 during use, so that when the mounting plate 7 drives the spinning assembly to move upward, the basket 3 moves upward synchronously, so that the sweet potato residue inside the basket 3 can be cleaned, and the cleaning of the sweet potato residue is more convenient.

[0051] In an optional embodiment, one end of the arc groove 12 is blocked to limit the position of the slider 11 in the arc groove 12, so that when the spinning assembly rotates and squeezes the sweet potato residue inside the basket 3, the basket 3 can be prevented from rotating.

[0052] In this embodiment, the telescopic rod 10 drives the mounting plate 7 to descend above the barrel 1, causing the mounting plate 7 to move the spinning assembly to the inside of the holding basket 3 to stir and squeeze the sweet potato residue inside the holding basket 3. The telescopic rod 10 then drives the mounting plate 7 to move upward, causing the slider 11 and the arc groove 12 to move the spinning assembly and the holding basket 3 upward synchronously. By rotating the holding basket 3, the holding basket 3 is separated from the mounting plate 7, allowing the sweet potato residue inside the holding basket 3 to be cleaned.

[0053] Example 4

[0054] like Figure 1-3 As shown, the present invention proposes a sweet potato starch extraction device. Compared with the first embodiment, the difference in this embodiment is that the spinning assembly includes a rotating shaft 4, a spiral plate 6, and a motor 8.

[0055] The motor 8 is mounted on the top of the mounting plate 7 and located above the middle of the barrel 1;

[0056] The rotating shaft 4 is mounted on the output shaft of the motor 8 and its bottom end extends to the inside of the holding basket 3;

[0057] The spiral plate 6 is located outside the rotating shaft 4 and at the bottom inside the holding basket 3.

[0058] In this embodiment, the motor 8 drives the rotating shaft 4 to rotate, which in turn drives the spiral plate 6 to rotate inside the holding basket 3. The spiral plate 6 causes the sweet potato residue and water inside the holding basket 3 to move upward, so that the sweet potato residue and water are fully mixed to form a starch slurry. The starch slurry is filtered through the filter bag 13 and mixed with the water in the barrel 1. At the same time, the starch slurry is discharged through the valve 2. The motor 8 is then reversed, so that the rotating shaft 4 moves the sweet potato residue inside the holding basket 3 towards the bottom of the holding basket 3 through the spiral plate 6. The sweet potato residue is squeezed at the bottom of the holding basket 3, and the starch slurry in the sweet potato residue is discharged into the barrel 1 through the filter bag 13, so that the starch in the sweet potato residue is extracted more thoroughly.

[0059] In this invention, sweet potato residue is placed inside the holding basket 3, and clean water is added to the inside of the bucket 1, allowing the water to pass through the filter bag 13 and come into contact with the sweet potato residue. The spiral plate 6 is moved downwards into the holding basket 3 by the cooperation of the telescopic rod 10 and the mounting plate 7, and the mounting plate 7 is fixed to the holding basket 3 by the hinge bolt 9. Simultaneously, rotating the holding basket 3 moves the slider 11 into the arc-shaped groove 12, thus limiting the rotation of the holding basket 3 in one direction. The motor 8 is then started, causing it to drive the spiral plate 6 to rotate inside the holding basket 3 via the rotating shaft 4. The spiral plate 6 also causes the sweet potato residue and water inside the holding basket 3 to move upwards, allowing the sweet potato residue and water to mix thoroughly, forming a starch slurry. The starch slurry is filtered through filter bag 13 and mixed with water in barrel 1. At the same time, the starch slurry is discharged through valve 2, and motor 8 is reversed, causing spiral plate 6 to move the sweet potato residue inside basket 3 to the bottom of basket 3. The sweet potato residue is squeezed at the bottom of basket 3, and the starch slurry in the sweet potato residue is discharged into barrel 1 through filter bag 13, so that the starch in the sweet potato residue is extracted more thoroughly and the starch extraction efficiency is higher. At the same time, the telescopic rod 10 drives the mounting plate 7 to move upward, so that the mounting plate 7 moves basket 3 upward synchronously and separates it from barrel 1. The handle 5 is rotated to separate basket 3 from mounting plate 7, which facilitates the discharge of sweet potato residue.

[0060] 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.
