Description

A starch separator for potato flour processing

Technical Field

The invention relates to the technical field of starch pretreatment processing, in particular to a starch separator used for potato flour processing.

Background technique

Starch can be regarded as a polymer of glucose. In addition to being edible, starch is also used in industry to make dextrin, maltose, glucose, alcohol, etc. It is also used to prepare printing paste, sizing of textiles, gluing of paper, pressing of pharmaceutical tablets, etc. It can be extracted from starch-containing substances such as corn, sweet potato, wild acorn and kudzu root. Tubers (such as sweet potatoes) are a type of crop with a high starch content and are often used as raw materials for starch production.

Detailed ways

The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

Embodiment 1: A starch separator for potato powder processing, as shown in Figures 1 and 2, includes a fixed frame 1, a crusher 2, a support frame 3, a drive motor 4, a solid-liquid centrifuge 5, a pulley group 6, a drainage frame 7, a first water injection pipe 8 and a washing component. The crusher 2 is installed on the fixed frame 1. Taking the potato crop sweet potato as an example, the sweet potato is cleaned before crushing and then put into the crusher 2 from the top of the crusher 2. The crusher 2 crushes the sweet potato into slag and discharges it from the bottom. The left side wall of the crusher 2 is fixed with the support frame 3 by bolts, and the drive motor 4 is installed on the support frame 3. The output shaft of the drive motor 4 penetrates into the crusher 2 and is connected to the crushing roller. The crusher 2 crushes the sweet potato with the crushing roller, and the discharge port below the crusher 2 is connected with the feed port of the solid-liquid centrifuge 5. The sweet potato slag discharged from the crusher 2 will enter the solid-liquid centrifuge 5 through the feed port for centrifugation. Solid-liquid separation, separating the solid of plant fiber residue and the water containing plant starch. The solid-liquid centrifuge 5 and the driving motor 4 are driven by a pulley group 6. The driving force of the crusher 2 can be used to drive the solid-liquid centrifuge 5 to work. The liquid discharge outlet of the solid-liquid centrifuge 5 is fixed by bolts with a discharge frame 7. The plant starch water centrifugally thrown out is discharged through the discharge frame 7. At this time, you only need to take a container to collect it. The crusher 2 is connected to a first water injection pipe 8, and the outlet of the first water injection pipe 8 is facing the crushing roller. When the crusher 2 is working, the first water injection pipe 8 is used to flush the crushing roller through an external water supply device. While avoiding the accumulation of sweet potato residue on the surface of the crushing roller, the sweet potato residue can also be diluted to avoid the condensation and scaling of plant starch that is difficult to discharge. A washing component for collecting residues and performing secondary cleaning is set at the solid discharge outlet of the solid-liquid centrifuge 5.

As shown in Figures 3 to 5, the washing assembly includes a collecting barrel 91, a connecting pipe 92, a top cover 93, a second water injection pipe 931, a first connecting plate 94, a bottom plate 95, a filter screen 96 and a limit clamp. The solid discharge port of the solid-liquid centrifuge 5 is fixedly connected to the collecting barrel 91, and the sweet potato residue separated by the solid-liquid centrifuge 5 will be discharged into the collecting barrel 91 through the solid discharge port.

The top of the collecting barrel 91 is fixedly connected to the top cover 93 to completely close the collecting barrel 91. The top cover 93 is connected to the second water injection pipe 931. When the collecting barrel 91 is filled with sweet potato residue separated from sweet potatoes, water can be injected into the collecting barrel 91 through the second water injection pipe 931 to rinse the sweet potato residue. As the water is injected to clean the sweet potatoes, the plant starch remaining in the sweet potato residue can be separated from the residue. This realizes secondary treatment of the sweet potato residue and further separates the residual plant starch in the residue. The lower part of the collecting barrel 91 is fixed with a first connecting plate 94 by bolts, and a bottom plate 95 is hinged on the first connecting plate 94. The bottom plate 95 is matched with the bottom size of the collecting barrel 91 and is used to close the bottom of the collecting barrel 91. A filter screen 96 is provided on the connecting pipe 92 leading to the drainage frame 7 on the collecting barrel 91. The filter screen 96 is close to the side wall of the collecting barrel 91. The plant starch water obtained by flushing the sweet potato residue will enter the connecting pipe 92 and be discharged from the drainage frame 7. The filter screen 96 can prevent the sweet potato residue from being discharged from the drainage frame 7 through the connecting pipe 92. A limit clamp for adjusting the opening and closing of the bottom plate 95 is provided at the lower part of the collecting barrel 91. Through the limit clamp, when the sweet potato residue in the collecting barrel 91 needs to be discharged, the limit clamp can be opened, and then the bottom plate 95 can be opened to discharge the residue in the collecting barrel 91.

The compression spring 103 is fixedly connected between the L-shaped clamp 102 and the fixed block 101. The compression spring 103 is used to keep the L-shaped clamp 102 clamped to the bottom plate 95. After the bottom plate 95 is closed, the end face in contact with the L-shaped clamp 102 is a plane, and the side opposite to the plane is an inclined surface. When the bottom plate 95 is below the L-shaped clamp 102, continuously pressing the bottom plate 95 upward will cause the bottom plate 95 to push the L-shaped clamp 102 away along the inclined surface of the L-shaped clamp 102 until the bottom plate 95 is above the L-shaped clamp 102, and then the L-shaped clamp 102 clamps the bottom plate 95 again.

As shown in Figures 8 and 9, it also includes a first pressing component, and the pressing component is arranged on the collecting cylinder 91; the first pressing component includes an electric push rod 111, a second connecting plate 112, a pressing rod 113 and a pressing grid 114. The electric push rod 111 is installed on the outer wall of the collecting cylinder 91 by bolts, and the movable rod of the electric push rod 111 is connected to the second connecting plate 112 by a key, and the pressing rod 113 is welded on the second connecting plate 112. The pressing rod 113 slides through the top cover 93 and penetrates into the collecting cylinder 91. The pressing grid 114 that is fixed to the pressing rod 113 inside the collecting cylinder 91 and is adapted to the inner diameter of the collecting cylinder 91 is fixed. As the electric push rod 111 pushes the pressing grid 114 on the pressing rod 113 downward, the sweet potato residue in the collecting cylinder 91 can be compacted during the downward movement, and then the plant starch can be squeezed out, and the sweet potato residue accumulated on the filter screen 96 can also be scraped off during the downward movement of the pressing grid 114.

As shown in FIGS. 9 to 12 , an unlocking assembly is also included, and an unlocking assembly is arranged on the lower pressure rod 113; the unlocking assembly includes a first fixed plate 121, a first connecting rod 122, a triangular plate 123, a curved toggle rod 124, a fixed collar 125, a positioning column 126, a notched ring 127 and a volute spring 128. The first fixed plate 121 is welded on the top of the lower pressure rod 113, the first connecting rod 122 is welded on the bottom of the first fixed plate 121, the triangular plate 123 is welded on the lower part of the first connecting rod 122, a fixed collar 125 is welded on the fixed block 101, the positioning column 126 is fixedly connected to the fixed collar 125, the notched ring 127 is rotatably connected to the fixed collar 125, the notched ring 127 is provided with a notch, the positioning column 126 is located in the notch, the fixed collar 125 is rotatably connected to the curved toggle rod 124, and the curved toggle rod 124 passes through the notch ring 127 and is fixed thereto, and the rotation range of the curved toggle rod 124 is limited to the notch ring 12 7, the rotation of the notch ring 127 will be restricted by the positioning column 126, the spiral spring 128 is fixed between the curved toggle rod 124 and the fixed collar 125, the triangular plate 123 is in contact with the curved toggle rod 124, and when the lower pressure rod 113 moves downward, the first fixed plate 121, the first connecting rod and the triangular plate 123 will move downward together, and after the triangular plate 123 touches the curved toggle rod 124 after the downward movement, the curved toggle rod 124 deflects downward until the triangle plate 123 continues to move downward so that the triangle plate 123 slides over the curved toggle rod 124. When the lower pressure rod 113 starts to move upward, the hypotenuse of the triangle plate 123 will contact the curved toggle rod 124, and the notch ring 127 is hindered by the positioning column 126 and cannot deflect, thereby pushing the L-shaped fixing block 101 to move. As the L-shaped fixing block 101 moves, the bottom plate 95 will be opened to allow the sweet potato residue in the collecting tube 91 to fall out.

As shown in Figure 13, it also includes a closing piece, and the closing piece is arranged at the bottom of the first fixed plate 121; the closing piece includes a second connecting rod 131 and a contact ball 132, the second connecting rod 131 is welded to the bottom of the first fixed plate 121, and the contact ball 132 is fixedly connected to the bottom of the second connecting rod 131. As the unlocking component opens the bottom plate 95 during the upward movement of the lower pressure rod 113, the contact ball 132 will contact the bottom plate 95 during the continuous upward movement of the lower pressure rod 113, thereby pushing the bottom plate 95 to flip upward until the bottom plate 95 is re-locked at the bottom of the collecting tube 91 and closed using the L-shaped block 102.

The cleaned sweet potato is put into the grinder 2 for grinding. During the grinding process, the water supply is turned on to inject water toward the grinding roller. The crushed sweet potato residue will enter the solid-liquid centrifuge 5. A container is placed under the drainage frame 7 to receive the separated plant starch water, and the separated sweet potato residue enters the collecting cylinder 91. Then, water is injected into the collecting cylinder 91 through the second water injection pipe 931 for flushing and soaking. The water after flushing and soaking contains the plant starch washed out from the sweet potato residue and will enter the drainage frame 7 through the connecting pipe 92, and be discharged into the container from the drainage frame 7. After the residue is cleaned, the sweet potato residue is compacted by squeezing through the first pressing component, and in the process of the pressing rod 113 moving upward, the bottom plate 95 will be opened by the unlocking component to discharge the compacted sweet potato residue.
