Description

Technical Field

[0001] This invention belongs to the technical field of potato deep processing, specifically, it relates to a high-efficiency extraction system and a green and environmentally friendly extraction method for potato residue dietary fiber. Background Technology

[0002] Potatoes are widely cultivated as an economic crop, and a wide variety of foods and feeds are made from them. Currently, most potato products on the market fall into two categories: the first category consists of unprocessed potato products, such as mashed potatoes, products mixed with mashed potatoes, French fries, and potato chips; the second category consists of extracted and separated potato products, such as starch and products mixed with starch. Neither of these categories utilizes potato dietary fiber for production. In most cases, after the starch is extracted from the potato during processing, the residue (potato pulp) is used as feed or discarded. However, potato pulp is rich in dietary fiber. Using it solely as feed significantly reduces its utilization efficiency. Furthermore, dietary fiber is primarily used as a substrate in animal husbandry; consuming large quantities would have the opposite effect on animal fattening. Aside from its use as a feed substrate, the remaining residue is simply discarded. This shows that the dietary fiber in potatoes cannot be used in suitable fields, and if it is not recycled, it will result in a waste of resources. Summary of the Invention

[0003] This invention provides a highly efficient extraction system and a green and environmentally friendly extraction method for potato residue dietary fiber, which can efficiently remove impurities from potatoes and effectively separate the dietary fiber from the potatoes using purely physical means, avoiding contamination of the dietary fiber during the extraction process, making the obtained dietary fiber safe, and can be used as a supplementary food to improve the gastrointestinal environment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-efficiency extraction system for dietary fiber from potato residue includes a peeling and impurity removal device, a vibrating slicing device, a press, a soaking tank, a filter cylinder, a continuous hot steaming device, and a drum dryer arranged sequentially along the potato processing sequence.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0019] This invention discloses a highly efficient extraction system for dietary fiber from potato residue, such as... Figure 1-23As shown, the system includes a peeling and impurity removal device 100, a vibrating slicing device 200, a press 300, a soaking tank 400, a filter cylinder 500, a continuous hot steaming device 600, and a drum dryer 700, arranged sequentially along the potato processing sequence. The peeling and impurity removal device 100 includes a passive feeding mechanism, a peeling mechanism, and a passive discharging mechanism, which are arranged sequentially along the potato conveying direction. The vibrating slicing device 200 includes multiple parallel conveying mechanisms, with slicing mechanisms installed at their outlet ends, and their inlet ends connected to the outlet end of the receiving box 217. The working principle and advantages of this invention are as follows: This invention uses a surface impurity removal device 100 to remove impurities such as mud from the potato skin. Then, the potato skin is removed, eliminating stubborn substances and moldy areas on the potato skin, ensuring the potatoes remain clean during subsequent processing. Next, the potatoes are sliced ​​to facilitate rapid and thorough removal of water during subsequent dehydration by pressing. The resulting potato residue is then soaked. During soaking, the soaking water in the soaking tank 400 is agitated to thoroughly remove non-dietary fiber, thereby improving separation efficiency. The residue is then filtered through a filter cylinder 500, and then pressed by rollers to force out moisture and form smaller pieces of residue into flakes. These flakes are then divided into smaller pieces and fed to a continuous steaming device 600, which steams the residue to obtain cooked potato residue. The cooked potato pulp is dried, cooled, and crushed to obtain dietary fiber powder, which can be used as a complementary food. In summary, this invention can efficiently remove impurities from potatoes and effectively separate dietary fiber from potatoes using purely physical methods, avoiding contamination of the dietary fiber during extraction, ensuring the safety of the obtained dietary fiber, and making it suitable as a complementary food to improve the intestinal environment.

[0020] As a preferred embodiment of the present invention, such as Figure 2-14As shown, the skin treatment mechanism includes a horizontal mounting cylinder 101, a rotary processing component, and a drive component. The rotary processing component is rotatably mounted within the processing chamber 102 of the horizontal mounting cylinder 101, with its axis coinciding with the axis of the rotary processing component. The drive component is located outside the horizontal mounting cylinder 101, with one end of the rotary processing component connected to the drive component. A drain connector 103 is constructed at the lower end of the outer peripheral wall of the horizontal mounting cylinder 101. In this embodiment, a skin cleaning zone 112, a skin steaming zone 113, and a skin removal zone 114 are formed within the rotary processing component, arranged sequentially along the potato conveying direction. In this embodiment, a feed channel 125 and a discharge channel 135 are formed at both ends of the rotary processing component. A passive feeding mechanism and a passive discharging mechanism are respectively connected to both ends of the rotary processing component, and the passive feeding mechanism and the passive discharging mechanism are respectively connected to the feed channel 125 and the discharge channel 135. The working principle and advantages of this embodiment are as follows: This embodiment controls the operation of the drive component to drive the rotary processing component to rotate within the horizontal mounting cylinder 101. Simultaneously, the passive feeding mechanism and the passive discharging mechanism operate accordingly, causing the potatoes entering the passive feeding mechanism to be gradually conveyed into the rotary processing component. During the process of passing through the skin cleaning zone 112, the mud on the surface of the potatoes is removed. Next, as the potatoes pass through the skin steaming zone 113, their skin is steamed, softening it and separating it from the potato flesh. Afterward, the potatoes enter the skin removal zone 114, where the skin and damaged parts of the potatoes are removed. The cleaned potatoes then enter the passive discharging mechanism and are finally discharged from the skin removal and impurity removal device 100. This embodiment achieves the purpose of removing impurities from potatoes through a step-by-step processing method, improving the thoroughness of impurity removal and ensuring that the cleanliness of the obtained potatoes meets or exceeds expectations. If, for example, impurities such as mud are not removed from the potato skin, the potato skin will be heated unevenly during the subsequent steaming process in the skin steaming zone 113 due to interference from the mud and other impurities. This can lead to situations where the skin cannot be easily removed from certain areas. Therefore, cleaning the skin impurities in the early stage is an essential step.

[0021] As a preferred embodiment of the present invention, such as Figure 4 , 11As shown in Figure 12, the rotary processing assembly includes a spiral guide blade 111 and multiple processing rollers. The multiple processing rollers are evenly arranged circumferentially along the horizontal mounting cylinder 101. These processing rollers are rotatably connected to the spiral guide blade 111, and these processing rollers enclose a cleaning chamber. During the cleaning process, the potatoes pass through the processing chamber 102. In this embodiment, each processing roller extends axially along the horizontal mounting cylinder 101, and the spiral guide blade 111 extends spirally along the axis of the horizontal mounting cylinder 101. The inner circumference of the spiral guide blade 111 extends into the cleaning chamber, and the outer circumference of the spiral guide blade 111 extends to the inner circumferential wall of the horizontal mounting cylinder 101. The working principle and advantages of this embodiment are as follows: This embodiment drives the rotary processing component to rotate through the driving component, so that the potatoes tumble and are gradually conveyed in the processing chamber 102. The conveying of potatoes is mainly achieved by the spiral guide blades 111. That is, as the spiral guide blades 111 rotate with the rotary processing component, the potatoes are conveyed by them. At the same time, the spiral guide blades 111 gradually convey the sludge, potato skins, etc. that fall into the processing chamber 102 of the horizontal installation cylinder 101 to the sewage discharge joint 103 and are discharged through the sewage discharge joint 103.

[0022] As a preferred embodiment of the present invention, such as Figure 4 , 11 As shown in Figure 12, the processing roller includes a first roller body 104, a second roller body 106, a third roller body 107, a first connecting rod 109, and a second connecting rod 110. The first roller body 104, the second roller body 106, and the third roller body 107 are sequentially connected together along the potato conveying direction. The first connecting rod 109 and the second connecting rod 110 are respectively constructed at opposite ends of the first roller body 104 and the third roller body 107. The first connecting rod 109 and the second connecting rod 110 are respectively drivenly connected to the axial ends of the horizontal mounting cylinder 101. The outer circumferential surfaces of the first roller body 104 and the third roller body 107 are respectively covered with first bristles 105 and second bristles 108. In this embodiment, the skin cleaning zone 112 is formed at the location of the cleaning chamber in the first roller body 104, the skin steaming zone 113 is formed at the location of the cleaning chamber in the second roller body 106, and the skin removal zone 114 is formed at the location of the cleaning chamber in the third roller body 107. In this embodiment, during the rotation of the rotary processing assembly, the first bristles 105 on the first roller 104 remove impurities from the potato skin, and the second bristles 108 on the third roller 107 peel off the potato skin. Furthermore, to improve the efficiency of impurity and skin removal and simultaneously avoid cleaning dead zones, this embodiment drives each processing roller to rotate simultaneously while the rotary processing assembly is rotating; that is, each processing roller revolves around the axis of the horizontal mounting cylinder 101 while rotating on its own axis.

[0023] As a preferred embodiment of the present invention, such as Figure 4-10As shown, internal cavities are constructed within the first roller 104, the second roller 106, and the third roller 107, respectively. These cavities are designated as a first conductive channel, a second conductive channel, and a third conductive channel, corresponding one-to-one with the first roller 104, the second roller 106, and the third roller 107. The first and second conductive channels are isolated from each other, while the second and third conductive channels are interconnected. A first connecting channel 115 is formed within the first connector rod 109, and a second connecting channel 133 is formed within the second connector rod 110. The first connecting channel 115 connects to the first conductive channel, and the second connecting channel 133 connects to the third conductive channel. The first roller 104, the second roller 106, and the third roller 107 are each covered with jet holes. In this embodiment, a first annular distribution seat and a second annular distribution seat are respectively installed at both axial ends of the horizontal mounting cylinder 101. Each first connector rod 109 is rotatably connected to the first annular distribution seat, and the first through hole 116 on the first connector rod 109 communicates with the first distribution cavity 119 of the first annular distribution seat. A first medium tube 120 is constructed on the first annular distribution seat, and the first medium tube 120 communicates with the first through channel through the first annular distribution seat and the first connector rod 109. Each second connector rod 110 is rotatably connected to the second annular distribution seat, and the second through hole 134 on the second connector rod 110 communicates with the second distribution cavity 128 of the second annular distribution seat. A second medium tube 129 is constructed on the second annular distribution seat, and the second medium tube 129 communicates with the second through channel through the second annular distribution seat and the second connector rod 110. High-pressure water enters the first distribution chamber 119 through the first medium pipe 120, and is then evenly distributed to each of the first guiding channels and ejected through the first roller 104. This causes the surface of the potatoes to be subjected to high-pressure washing during the tumbling and conveying process, removing impurities and providing preliminary treatment for moldy parts of the potatoes. High-pressure steam enters the second distribution chamber 128 through the second medium pipe 129, and is then evenly distributed to each of the second and third guiding channels. It is then ejected through the second roller 106 and the third roller 107. During the tumbling and conveying process, the potato skin is softened and cooked in the skin steaming zone 113, and finally removed in the skin removal zone 114. The first bristles 105 and the second bristles 108 not only remove impurities and skin, but also effectively treat moldy parts of the potatoes, and the hot steam effectively kills bacteria carried on the potatoes.The first annular distribution seat in this embodiment includes a first annular rotating part 117 and a first annular fixing part 118. The first medium tube 120 is constructed on the first annular fixing part 118. The first annular rotating part 117 is coaxially rotatably connected to the axial end of the horizontal mounting cylinder 101. The first annular fixing part 118 is fixed to the axial end of the horizontal mounting cylinder 101 and is coaxially rotatably connected to the outside of the first annular rotating part 117. The first distribution cavity 119 is formed between the first annular fixing part 118 and the first annular rotating part 117, and the first annular rotating part 117 is drive-connected to the drive assembly. The second annular distribution seat in this embodiment includes a second annular rotating part 126 and a second annular fixing part 127.

The second annular fixing part 127 is fixed to the other axial end of the horizontal mounting cylinder 101 and is coaxially rotatably connected to the outside of the second annular rotating part 126. The second distribution cavity 128 is formed between the second annular fixing part 127 and the second annular rotating part 126. In this embodiment, a transmission gear 130 is coaxially mounted on each second connector rod 110. An internal gear ring 131 is coaxially fixed on the horizontal mounting cylinder 101, and each transmission gear 130 meshes with the internal gear ring 131. A protective cover 132 is constructed on the second annular rotating part 126. The protective cover 132 encloses the internal gear ring 131 and each transmission gear 130 within it to protect the internal gear ring 131 and each transmission gear 130. The drive assembly of this embodiment includes a drive motor 121, a first transmission wheel 122, a second transmission wheel 123, and a transmission belt 124. The output shaft of the drive motor 121 is coaxially connected to the first transmission wheel 122, which is coaxially connected to the outside of the first annular rotating part 117. The first transmission wheel 122 and the second transmission wheel 123 are connected together by transmission belt 124. In this embodiment, by controlling the operation of the drive motor 121, it drives the first annular rotating part 117 to rotate. During the rotation of the first annular rotating part 117, it drives each processing roller to rotate along the axis of the horizontal mounting cylinder 101. At the same time, under the transmission of the transmission gear 130 and the internal gear ring 131, the processing rollers rotate on their own.

[0024] As a preferred embodiment of the present invention, such as Figure 13As shown, the passive feeding mechanism includes a first conveying cylinder 136, a first conveying blade 137, a first rotating sleeve 138, and a first guide hopper 139.

The second guide hopper 143 is constructed at the lower part of the second rotating sleeve 142 and communicates with the inner cavity of the second conveying cylinder 140. The second guide hopper 143 is fixed to a corresponding part of a nearby frame. In this embodiment, the rotary processing component is driven to rotate by the driving component, which causes the first conveying cylinder 136 and the second conveying cylinder 140 to rotate synchronously. During the rotation of the first conveying cylinder 136 and the second conveying cylinder 140, the potatoes inside are gradually conveyed, thereby achieving the purpose of feeding and unloading the rotary processing component.

One end of the connecting post 207 passes through the adapter seat 208, and a fixing nut 209 is threaded onto the connecting post 207. The fixing nut 209 is tightened onto the adapter seat 208, thereby fixing the transmission rod 205 to the adapter seat 208. In this embodiment, a longitudinal drive member 216 is connected to the adapter seat 208, and the longitudinal drive member 216 extends along the axis of the transmission rod 205. A vertical pressing assembly is provided above the receiving box 217. The vertical pressing assembly includes a pressing seat 220, which extends from the upper port of the receiving box 217 into the receiving cavity 218. Two vertical driving members 221 are installed on the upper end of the pressing seat 220. The aforementioned longitudinal driving member 216 and vertical driving member 221 can be electric cylinders, pneumatic cylinders, or hydraulic cylinders. The slicing mechanism of this embodiment includes a power motor 214 and multiple mounting shafts 211. A connecting ear 210 is constructed at the lower part of each horizontal guide cylinder 201. Each mounting shaft 211 is rotatably connected to the corresponding connecting ear 210. A synchronous pulley 212 and a cutting blade 213 are coaxially mounted on the mounting shaft 211. The cutting blade 213 is located at the outlet end of the corresponding horizontal guide cylinder 201. The output shaft of the power motor 214 is coaxially connected to one of the mounting shafts 211, and all the synchronous pulleys 212 are connected by a synchronous transmission belt 215.The working principle and advantages of this embodiment are as follows: When the potatoes to be sliced ​​are filled into the receiving cavity 218, the vertical drive member 221 is controlled to drive the lower pressure seat 220 to extend into the receiving cavity 218, and the lower pressure seat 220 is controlled to always press on the uppermost layer of the potatoes; the power motor 214 of the slicing mechanism is controlled to operate, so that it drives each cutting blade 213 to rotate; at the same time, the longitudinal drive member 216 is controlled to reciprocate along the longitudinal direction. The longitudinal drive member 216 drives each transmission rod 205 through the adapter seat 208. Under the action of the buffer spring 206, the transmission rod 205 drives the material cylinder 203 to reciprocate in the horizontal guide cylinder 201, so that the push head 204 horizontally and elastically presses against the potatoes near the horizontal guide cylinder 201. The horizontal guide cylinder 201 contains multiple potatoes. Under the action of the push head 204, the potatoes near the slicing mechanism are gradually discharged from the outlet end of the horizontal guide cylinder 201 and are sliced ​​during the discharge process. In this embodiment, the longitudinal drive component 216 is controlled to reciprocate, causing the feed cylinder 203 to reciprocate within the horizontal guide cylinder 201. Under the action of the vertical pressing component, the potatoes in the receiving cavity 218 gradually enter the horizontal guide cylinder 201, ensuring continuous feeding and facilitating continuous slicing of the potatoes, thus improving slicing efficiency. Furthermore, the use of multiple feeding mechanisms for slicing further enhances slicing efficiency.

[0026] As a preferred embodiment of the present invention, such as Figure 20-23As shown, the continuous hot steaming device 600 includes a hot steaming casing 601, a conveying unit 607, and a hot steam cleaning piping system. A steam collecting hood 602 and a water collecting hood 605 are respectively constructed at the upper and lower ends of the hot steaming casing 601. Multiple exhaust connectors 603 are spaced apart at the upper end of the steam collecting hood 602 along the conveying direction of the conveying unit 607. These exhaust connectors 603 are all connected to exhaust pipes 604, which are connected to a suction device. A drain connector 606 is constructed at the lower end of the water collecting hood 605. In this embodiment, the conveying unit 607 is located inside the hot steaming casing 601. The conveying unit 607 includes two drive rollers arranged side by side, which are rotatably connected via a conveyor belt. Driving one of the drive rollers to rotate drives the conveyor belt, thereby conveying the material. The conveyor belt is covered with holes, and the hot steam cleaning piping system extends into the gaps in the conveyor belt. The thermal steam cleaning system of this embodiment includes multiple dual-medium pipes 608. These dual-medium pipes 608 are spaced apart along the conveying direction of the conveying unit 607. Each dual-medium pipe 608 extends between the upper and lower parts of the conveyor belt. A first medium cavity 609 and a second medium cavity 610 are formed downwards within each dual-medium pipe 608. Spray holes are distributed at both the upper and lower ends of each dual-medium pipe 608. A first medium connector 611 and a second medium connector 612 are respectively constructed at the upper and lower ends of each dual-medium pipe 608. The first medium connector 611 and the second medium connector 612 are respectively connected to the first medium cavity 609 and the second medium cavity 610. A first medium main pipe 613 is connected to each of the first medium connectors 611, and a second medium main pipe 614 is connected to each of the second medium connectors 612. The working principle and advantages of this embodiment are as follows: This embodiment controls the operation of the conveying unit 607, enabling continuous material transport on the conveyor belt. Simultaneously, hot steam and cleaning water are introduced into the first medium main pipe 613 and the second medium main pipe 614, respectively. Hot steam is ejected from the first medium chamber 609 through the upper end of the dual medium pipe 608, and steam is applied to the material on the conveyor belt. Excess hot steam is discharged through the exhaust joint 603 and exhaust pipe 604. Cleaning water is ejected from the second medium chamber 610 through the lower end of the dual medium pipe 608, and jets onto the lower part of the conveyor belt, washing away any material adhering to the conveyor belt and preventing it from being discharged. This allows the material to be transported smoothly when the lower part of the conveyor belt rotates to the upper part. The remaining material washed off falls into the water collection hood 605 and is then discharged through the drain joint 606.
