Description

Technical Field

[0001] The utility model relates to the technical field of potato processing equipment, in particular to a potato skin pretreatment system. Background Art

[0002] The process of peeling potatoes by steam blanching includes washing the potatoes to remove stones and dirt, peeling them by steam blanching, and finally peeling them by a peeling device.

[0003] Specifically, it can be understood as follows: first, the potatoes are washed for the first time in a drum washing machine to clean the stubborn sand, dirt, etc. attached to the surface, and remove most of the dirt, sand and debris stuck to the surface of the potatoes; then the potatoes are transported to a spray washing machine for cleaning with high-pressure water flow to remove the remaining dirt, sand and other impurities on the surface of the potatoes; then, the cleaned potatoes are transported to a blanching device for blanching with steam; finally, the blanched potatoes are transported to a peeling tank for peeling; finally, the blanching and peeling process of the potatoes is completed.

[0004] However, when the potato blanching system in the prior art is in operation, the washing water after washing the potatoes in the washing machine contains impurities such as sand, stone, and soil, and the steam after blanching contains impurities and non-condensable gases. Therefore, the washing water after washing the potatoes in the washing machine is usually directly discharged away, and the steam after blanching the potatoes is directly discharged into the atmosphere, which undoubtedly causes a waste of water resources.

[0005] Therefore, the potato blanching system in the prior art has the problem of directly discharging the washing water after washing the potatoes in the washing machine and directly discharging the steam after blanching the potatoes into the atmosphere, resulting in a waste of water resources. Utility Model Content

[0006] The utility model aims to solve the problem in the prior art that the washing water after washing potatoes in the washing machine is directly discharged away, and the steam after blanching potatoes is directly discharged into the atmosphere, causing water waste.

[0007] In order to solve the above problems, the utility model provides a potato blanching pretreatment system, comprising: a cleaning component, a filtering component, a heat exchange component and a blanching component; wherein the cleaning component comprises a cleaning shell with a accommodating space, and a cleaning component arranged inside the cleaning shell to clean the surface of the potato, the upper end of the cleaning shell is provided with an openable cleaning upper cover, the cleaning upper cover is provided with a cleaning water inlet, and the lower end of the cleaning shell is provided with a cleaning drain outlet; a filter element component is provided inside the filtering component, and the filtering water inlet at one end of the filtering component is connected to the cleaning drain outlet pipeline of the cleaning component, and the other end of the filtering component is also provided with a filtering drain outlet.

[0008] Furthermore, the blanching component includes a hollow blanching shell, a heating component arranged at the lower part of the blanching shell, and a blanching cover body with an openable cover arranged at the upper end of the blanching shell. A blanching water inlet and a steam outlet are respectively provided at the opposite ends of the blanching shell, and the filter drain outlet is connected to the blanching water inlet pipeline; and the heat exchange component includes a cleaning water channel and a steam condensation channel. The cleaning water channel extends from the filter drain outlet pipeline to the blanching water inlet, and the steam condensation channel extends from the steam outlet pipeline to the blanching water inlet, and partially bends and extends through the inside of the cleaning water channel.

[0009] By adopting the above technical solution, when the potato blanching pretreatment system is in operation, the cleaning cover is opened, the potatoes are placed in the accommodating space of the cleaning shell, and then the cleaning cover is closed, water is injected into the cleaning shell from the cleaning water inlet, and the potatoes are cleaned through the cleaning components; the cleaning water after cleaning the potatoes is discharged from the cleaning drain port of the cleaning shell, and flows from the pipeline to the filter water inlet of the filter component, and enters the filter component for filtration; the filtered cleaning water is discharged from the filter drain port of the filter component, and flows from the pipeline to the cleaning water channel, and flows through the cleaning water channel to the blanching water inlet of the blanching component and enters the blanching component.

[0010] Furthermore, while the cleaning component is cleaning the potatoes, the pre-cleaned potatoes are placed into the blanching component, and the water is heated by the heating component to generate steam, thereby blanching the potatoes in the blanching component. The steam after blanching flows out through the steam outlet of the blanching component through the pipeline to the steam condensation channel; and, since the steam condensation channel is partially curved and extends through the inside of the cleaning water channel, the steam after blanching will be condensed by the cleaning water in the cleaning water channel, thereby being condensed into condensed water, and then enters the blanching component again for recycling.

[0011] To sum up, when the potato blanching pretreatment system provided by this solution is used, the washing water is filtered by the filtering component, and then recycled to the blanching component for vaporization to achieve the purpose of water resource recycling; and the steam from the blanched potatoes is condensed with the filtered washing water and recycled again to achieve the purpose of water resource recycling; therefore, it has the advantage of improving the utilization rate of water resources.

[0012] According to the potato blanching pretreatment system provided by the embodiment of the present invention, the cleaning component is arranged above the filtering component; and the filtering component includes a first filtering component and a second filtering component arranged in sequence along the flow direction of the cleaning water, and in the vertical direction, the first filtering component is arranged above the second filtering component; wherein, the filtering water inlet is arranged at the upper end of the first filtering component, the drain outlet of the filtering component is arranged at the lower end of the second filtering component, and the lower end of the first filtering component and the upper end of the second filtering component are connected through a pipeline fluid.

[0013] Furthermore, the filter element component includes a first filter element arranged horizontally in the first filter component, and a second filter element arranged horizontally in the second filter component. The filter pores of the first filter element are larger than the filter pores of the second filter element, and the cleaning water from the cleaning drain outlet flows into the first filter component through the filter water inlet, flows into the second filter component after being filtered by the first filter element, and enters the cleaning water channel through the filter drain outlet after being filtered again by the second filter element.

[0014] With the above technical solution, the cleaning assembly is positioned above the filtration assembly, allowing the potato water to be promptly drained from the cleaning assembly into the filtration assembly, ensuring system reliability. The pores of the first filter element are larger than those of the second filter element. When the potato water is filtered through the filtration assembly, the first filter element in the first filter component first filters out larger impurities, such as sand and gravel; the second filter element in the second filter component then filters out smaller impurities, such as dirt. Thus, the two-stage filtration ensures that the potato water is completely filtered, and when it is then passed into the blanching assembly for vaporization, the generation of impurities is reduced.

[0015] According to the potato skin pretreatment system provided by the embodiment of the present invention, the first filter component includes a filter box, the filter box of the first filter component includes a water inlet chamber and a water outlet chamber, in the vertical direction, the water inlet chamber is located above the water outlet chamber, the filter water inlet is opened on the top wall surface of the water inlet chamber, the first filter element of the filter element component is arranged between the water inlet chamber and the water outlet chamber and is fixed and detachably connected to the inner wall surface of the filter box of the first filter component, the drain outlet of the first filter component is opened on the bottom wall surface of the water outlet chamber, and the water outlet chamber is arranged in a "V" shape.

[0016] By adopting the above technical solution, the first filter component is provided with a water inlet chamber and a water outlet chamber. When the cleaning water of the potatoes after being cleaned by the cleaning component is discharged into the filter component, it first enters the water inlet chamber of the first filter component, and then passes through the first filter element of the filter core component to filter out larger impurities before entering the water outlet chamber; by providing the water inlet chamber and the water outlet chamber, the cleaning water entering the first filter component has a storage function, thereby avoiding the problem of cleaning water being retained in the cleaning component due to the slow filtering speed of the first filter element of the filter core component.

[0017] Furthermore, the water outlet cavity is arranged in a "V" shape, and the cleaning water filtered by the first filter element of the filter element component can be quickly collected at the drain port of the first filter component and discharged through the drain port of the first filter component.

[0018] According to the potato skin pretreatment system provided by the embodiment of the present invention, the second filter component includes a water filter box, and the water filter box of the second filter component includes a water inlet chamber and a drainage chamber. In the vertical direction, the water inlet of the second filter component is opened on the top wall surface of the water inlet chamber, and the filter drainage outlet is opened on the side wall of the drainage chamber. The second filter element of the filter element component is arranged between the water inlet chamber and the drainage chamber and is fixedly and detachably connected to the inner wall surface of the water filter box of the second filter component; and the drainage outlet of the first filter component is connected to the water inlet of the second filter component through a first auxiliary pipeline, and a first drainage valve is provided on the first auxiliary pipeline, and a second drainage valve is also provided at the filter drainage outlet.

[0019] Furthermore, the volume V1 of the drainage chamber, the volume V2 of the water inlet chamber, the volume V3 of the water inlet chamber, and the volume V4 of the water outlet chamber are set to: V1>V2>V3>V4.

[0020] Using the above technical solution, the second filter component is provided with a water inlet chamber and a drain chamber. After the cleaning water filtered by the first filter element enters the water inlet chamber through the first auxiliary pipeline, it is filtered by the filter element of the filter element to remove small impurities before entering the drain chamber and finally being discharged from the drain chamber. The provision of the water inlet chamber and the drain chamber acts as a storage chamber for the cleaning water entering the second filter element, thus avoiding the problem of cleaning water being retained in the first filter element due to the slow water filtering speed of the second filter element. In addition, a first drain valve is provided on the first auxiliary pipeline to control the drainage speed of the first filter element to the second filter element. If the second filter element is unable to filter the cleaning water from the first filter element in time, the first drain valve can be closed to stop the first filter element from supplying water to the second filter element. The filter drain outlet is also provided with a second drain valve. When the blanching component is not in operation, the second drain valve can be closed to control the filter element's water supply to the cleaning water channel.

[0021] Furthermore, the volume V1 of the drainage chamber, the volume V2 of the water inlet chamber, the volume V3 of the water inlet chamber, and the volume V4 of the water outlet chamber are set to: V1>V2>V3>V4; since the filtered cleaning water finally enters the drainage chamber, the volume of the drainage chamber is set to the maximum, so that the filtered cleaning water can have sufficient storage function.

[0022] According to the potato blanching pretreatment system provided by the embodiment of the present invention, the cleaning component includes a vibrating screen plate, a brushing component and a spraying component arranged in a cleaning shell; in the vertical direction, the cleaning drain outlet is opened on the bottom wall surface of the cleaning shell, and the vibrating screen plate is horizontally arranged in the cleaning shell for placing potatoes; the spraying component is fixed on the side wall of the cleaning shell, located above the vibrating screen plate, and the nozzle of the spraying component is downward facing the vibrating screen plate; the brushing component is installed on the side wall of the cleaning shell, located between the spraying component and the vibrating screen plate, and the brushing roller of the brushing component is opposite to the vibrating screen plate and can move above the vibrating screen plate along the width direction of the cleaning shell.

[0023] Furthermore, when the cleaning component cleans the potatoes placed on the vibrating screen plate, the nozzle of the spraying component sprays water toward the potatoes on the vibrating screen plate, and the brushing roller moves along the width direction of the cleaning shell to brush the potatoes on the vibrating screen plate. At the same time, the vibrating screen plate vibrates at a high frequency and the potatoes on the vibrating screen plate roll on the vibrating screen plate.

[0024] According to the above technical solution, when cleaning potatoes, since the potatoes are dug out from the soil, the surface of the potatoes is adhered to dirt, sand, and gravel. Therefore, during the cleaning process, water is first sprayed onto the potatoes through the nozzle of the spraying component, thereby soaking the potatoes and loosening and falling off the dirt, sand, and gravel adhered to the surface of the potatoes. Then, the surface of the potatoes is scrubbed by the scrubbing roller to make the surface clean. The vibrating screen plate vibrates and rolls the potatoes placed thereon, so that the surface of the potatoes is completely cleaned.

[0025] According to an embodiment of the present invention, the potato blanching pretreatment system includes a spraying component comprising a water pump mounted vertically on the top outer wall of a washing housing, and a plurality of nozzles mounted on the top inner wall of the washing housing. The water pump passes through the top wall of the washing housing and is connected to the plurality of nozzles. The vibrating screen plate includes a vibration motor and a screen plate. The vibration motor is mounted on the inner wall of the washing housing and is in transmission connection with the screen plate to drive the screen plate to vibrate. The screen plate is parallel to the top wall of the washing housing.

[0026] Furthermore, a slide groove is opened on the side wall of the cleaning shell along the width direction of the cleaning component; the brushing component includes a brushing roller, a sliding seat and a driving motor, wherein the sliding seat is slidably connected to the slide groove; one end of the brushing roller is rotatably connected to the side wall of the sliding seat, and the other end extends along the width direction of the cleaning component and is located above the screen plate, and the outer peripheral wall of the brushing roller is provided with bristles; the driving motor is installed on the side wall of the cleaning shell and is transmission-connected to the sliding seat, for driving the sliding seat to slide in the slide groove.

[0027] Using this technical solution, when cleaning dirt and gravel from the surface of potatoes, water is injected into the pump pipe and sprayed toward the potatoes through multiple nozzles to clean the potatoes. Simultaneously, a drive motor drives the sliding seat and the scrubbing roller to reciprocate, scrubbing the potato surface. Simultaneously, a vibration motor drives the sieve plate to vibrate, and the potatoes roll on the sieve plate, completely cleaning the potato surface. Furthermore, because the potato surface is irregular, bristles are provided on the surface of the scrubbing roller, ensuring that the entire potato surface is covered and scrubbed.

[0028] Furthermore, since the scrubbing roller is located between the multiple nozzles and the sieve plate, the brush bristles on the surface of the scrubbing roller can also be rinsed when the spraying component sprays the potatoes, thereby preventing dirt and sand from adhering to the bristles and reducing the degree of scrubbing of the potato surface by the bristles, thereby ensuring that the bristles can better clean the potatoes.

[0029] According to the potato blanching pretreatment system provided in the embodiment of the present invention, the cleaning water channel includes a heat exchange pool arranged in communication with the filter drain outlet and the blanching water inlet, and arranged in the connecting pipeline; the middle part of the steam condensation channel is spirally curved and passes through the heat exchange pool; wherein, the downstream part of the cleaning water channel and the downstream part of the steam condensation channel are merged into a mixing pipeline, and the downstream end of the mixing pipeline is connected to the blanching water inlet.

[0030] With this technical solution, when both the filtration and blanching components are operating, the rinse water filtered by the filtration component enters the heat exchange tank through a connecting pipe. Simultaneously, steam from blanching potatoes in the blanching component enters the steam condensation channel. As the steam passes through the middle of the steam condensation channel, it exchanges heat with the rinse water in the heat exchange tank, condensing into condensed water. Furthermore, the rinse water and condensed water flow through a mixing pipe, pass through the blanching water inlet, and then enter the blanching component, where they are vaporized and recycled, reducing water waste.

[0031] Furthermore, the central portion of the steam condensation channel is spirally curved and passes through the heat exchange tank, increasing the condensation distance and area of ​​the steam, thereby ensuring complete condensation. The downstream portion of the wash water channel is combined with the downstream portion of the steam condensation channel to form a mixing pipeline, which ensures that the temperature of the wash water and condensed water remains consistent after mixing, facilitating heating and vaporization of the blanching component, with the advantages of fast and complete vaporization.

[0032] According to the potato skin pretreatment system provided by the embodiment of the present invention, a condensation water tank is further provided in the downstream part of the steam condensation channel, and in the vertical direction, the condensation water tank is located below the heat exchange pool, and the condensation water tank is arranged downstream of the pipeline part passing through the heat exchange pool in the steam condensation channel and upstream of the mixing pipeline; and in the vertical direction, a non-condensable gas exhaust port is opened on the top wall surface of the condensation water tank, and a non-condensable gas discharge valve and a non-condensable gas fan are provided at the non-condensable gas exhaust port.

[0033] By adopting the above technical solution, since non-condensable gas will be produced after steam is condensed into condensed water, the setting of a condensate water tank can, on the one hand, quickly collect the condensed water; on the other hand, after the non-condensable gas enters the condensate water tank, the non-condensable steam discharge valve can be opened to discharge the non-condensable gas; and, by setting a non-condensable gas fan, the discharge speed of the non-condensable gas can be accelerated, thereby avoiding the non-condensable gas from entering the blanching component again, ensuring the quality of the steam generated by the subsequent blanching component and the blanching effect of the blanching component on potatoes.

[0034] According to the potato blanching pretreatment system provided by the embodiment of the present invention, a drain valve is further provided at the cleaning drain outlet of the cleaning component, a first booster pump is provided in the cleaning water channel and upstream of the heat exchange tank, and a second booster pump is provided in the mixing pipeline.

[0035] By adopting the above technical solution, the amount of water discharged by the cleaning component to the filter component can be controlled by setting a drain valve. When the filter component is blocked or the filtration speed is slow, the drain valve can be closed to disassemble and repair the filter component or wait for the filter component to completely clean the cleaning water.

[0036] Furthermore, a first booster pump is provided upstream of the heat exchange tank, and a second booster pump is provided in the mixing pipeline. The booster pump can boost the water flow in the pipeline, thereby avoiding the problem of backflow of the water flow in the pipeline.

[0037] According to the potato peeling pretreatment system provided by the embodiment of the present invention, a waste steam treatment device and a negative pressure pump arranged in sequence along the steam conveying direction are also provided upstream of the pipeline portion passing through the heat exchange tank in the steam condensation channel, wherein the steam exhaust port is connected to the air inlet pipeline of the waste steam treatment device, the exhaust port of the waste steam treatment device is connected to the air inlet pipeline of the negative pressure pump, and the air outlet of the negative pressure pump is connected to the steam condensation channel.

[0038] According to the above technical solution, a large amount of steam is generated during the blanching process of potatoes, and the steam after blanching needs to be quickly discharged. Therefore, a negative pressure pump is provided in the steam condensation channel so that the steam after blanching can be quickly pumped out into the steam condensation channel by the negative pressure pump.

[0039] Furthermore, during the scalding process, the steam needs to be discharged quickly, so the negative pressure pump will give the steam negative pressure, so that the steam will carry a small amount of potato peels and mud and sand remaining on the potato peels during the discharge process. Therefore, by setting up a waste steam treatment device, the steam entering the steam condensation channel can be purified to prevent the potato peels and mud and sand it carries from contaminating the condensate water.

[0040] The beneficial effects of the present invention are:

[0041] The utility model provides a potato blanching pretreatment system, comprising: a cleaning component, a filtering component, a heat exchange component and a blanching component; wherein the cleaning component comprises a cleaning shell with a accommodating space, and a cleaning component arranged inside the cleaning shell for cleaning the surface of the potato, the upper end of the cleaning shell is provided with an openable cleaning upper cover, the cleaning upper cover is provided with a cleaning water inlet, and the lower end of the cleaning shell is provided with a cleaning drain outlet; a filter element component is provided inside the filtering component, and the filtering water inlet at one end of the filtering component is connected to the cleaning drain outlet pipeline of the cleaning component, and the other end of the filtering component is also provided with a filtering drain outlet.

[0042] Furthermore, the blanching component includes a hollow blanching shell, a heating component arranged at the lower part of the blanching shell, and a blanching cover body with an openable cover arranged at the upper end of the blanching shell. A blanching water inlet and a steam outlet are respectively provided at the opposite ends of the blanching shell, and the filter drain outlet is connected to the blanching water inlet pipeline; and the heat exchange component includes a cleaning water channel and a steam condensation channel. The cleaning water channel extends from the filter drain outlet pipeline to the blanching water inlet, and the steam condensation channel extends from the steam outlet pipeline to the blanching water inlet, and partially bends and extends through the inside of the cleaning water channel.

[0043] Furthermore, when the potato blanching pretreatment system is in operation, the cleaning cover is opened, the potatoes are placed in the accommodating space of the cleaning shell, and then the cleaning cover is closed, water is injected into the cleaning shell from the cleaning water inlet, and the potatoes are cleaned through the cleaning components; the cleaning water after cleaning the potatoes is discharged from the cleaning drain port of the cleaning shell, and flows from the pipeline to the filter water inlet of the filter component and enters the filter component for filtration; the filtered cleaning water is discharged from the filter drain port of the filter component and flows from the pipeline to the cleaning water channel, and flows through the cleaning water channel to the blanching water inlet of the blanching component and enters the blanching component.

[0044] Furthermore, while the cleaning component is cleaning the potatoes, the pre-cleaned potatoes are placed into the blanching component, and the water is heated by the heating component to generate steam, thereby blanching the potatoes in the blanching component. The steam after blanching flows out through the steam outlet of the blanching component through the pipeline to the steam condensation channel; and, since the steam condensation channel is partially curved and extends through the inside of the cleaning water channel, the steam after blanching will be condensed by the cleaning water in the cleaning water channel, thereby being condensed into condensed water, and then enters the blanching component again for recycling.

[0074] The potato blanching equipment performs two main functions: blanching and pretreatment. Blanching involves applying high-temperature steam to soften the potato skin, facilitating subsequent peeling. Pretreatment also includes a washing step to ensure the potatoes remain clean for subsequent processing.

[0075] However, in the prior art potato blanching system, the washing water after washing the potatoes in the washing machine contains impurities such as sand, dirt, and the steam after blanching contains impurities and non-condensable gases. Therefore, the washing water after washing the potatoes in the washing machine is usually directly discharged away, and the steam after blanching the potatoes is directly discharged into the atmosphere, resulting in a waste of water resources.

[0076] In order to solve the above problems, the present invention provides a potato blanching pretreatment system. When in use, the potato blanching pretreatment system provided by this solution filters the washing water through the filtering component, and then recycles it to the blanching component for vaporization to achieve the purpose of water resource recycling; and the steam from the blanched potatoes is condensed with the filtered washing water and recycled again to achieve the purpose of water resource recycling; therefore, it has the advantage of reducing water resource waste.

[0077] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0078] First, the potato blanching pretreatment system is generally described.

[0079] like Figure 1-Figure 3 As shown, an embodiment of the present invention discloses a potato blanching pretreatment system, comprising: a cleaning component 1 for cleaning potatoes, a filtering component 2 for filtering washing water after washing potatoes, a heat exchange component 3 and a blanching component 4 for blanching potatoes.

[0080] Specifically, the cleaning assembly 1 includes a cleaning shell 11 with a accommodating space, and a cleaning component 10 arranged inside the cleaning shell 11 to clean the surface of potatoes. The upper end of the cleaning shell 11 has an openable cleaning cover 12, and the cleaning cover 12 is provided with a cleaning water inlet 14, and the lower end of the cleaning shell 11 has a cleaning drain outlet 15; when cleaning potatoes, the cleaning cover 12 is opened, and the potatoes are placed in the accommodating space of the cleaning shell 11, and then the cleaning cover 12 is closed, water is injected into the cleaning shell 11 from the cleaning water inlet 14, and the potatoes are scrubbed by the cleaning component 10.

[0081] More specifically, a filter element 20 is provided within the filter assembly 2. A filter water inlet 26 at one end of the filter assembly 2 is connected to the wash drain 15 of the washing assembly 1 by a pipe. A filter drain 27 is also provided at the other end of the filter assembly 2. The blanching assembly 4 includes a hollow blanching housing, a heating element disposed at the lower portion of the blanching housing, and a blanching cover that is removably disposed at the upper end of the blanching housing. A blanching water inlet 40 and a steam outlet 41 are provided at opposite ends of the blanching housing, respectively. The filter drain 27 is connected to the blanching water inlet 40 by a pipe. Furthermore, the heat exchange assembly 3 includes a wash water channel 30 and a steam condensation channel 31. The wash water channel 30 extends from the filter drain 27 to the blanching water inlet 40 by a pipe, while the steam condensation channel 31 extends from the steam outlet 41 to the blanching water inlet 40 by a pipe. The steam condensation channel 31 partially curves and extends through the interior of the wash water channel 30.

[0082] More specifically, the working principle of this potato peeling pretreatment system is as follows:

[0083] When this potato blanching pretreatment system is in operation, the cleaning cover 12 is opened, and potatoes are placed in the accommodating space of the cleaning shell 11. Then, the cleaning cover 12 is closed, water is injected into the cleaning shell 11 from the cleaning water inlet 14, and the potatoes are cleaned through the cleaning component 10; the cleaning water after cleaning the potatoes is discharged from the cleaning drain port 15 of the cleaning shell 11, and flows from the pipeline to the filter water inlet 26 of the filter component 2 to enter the filter component 2 for filtration; the filtered cleaning water is discharged from the filter drain port 27 of the filter component 2, and flows from the pipeline to the cleaning water channel 30, and flows through the cleaning water channel 30 to the blanching water inlet 40 of the blanching component 4 and enters the blanching component 4.

[0084] Furthermore, while washing the potatoes, the cleaning component 1 places the pre-washed potatoes into the blanching component 4, and heats the water through the heating component to generate steam, thereby blanching the potatoes in the blanching component 4. The steam after blanching flows out through the steam outlet 41 of the blanching component 4 through the pipeline to the steam condensation channel 31; and, since the steam condensation channel 31 is partially bent and extends through the inside of the washing water channel 30, the steam after blanching will be condensed by the washing water in the washing water channel 30, thereby being condensed into condensed water, and then enters the blanching component 4 again for recycling.

[0085] To sum up, when the potato blanching pretreatment system provided by this solution is used, the cleaning water is filtered by the filter component 2, and then recycled to the blanching component 4 for vaporization to achieve the purpose of water resource recycling; and the steam from the blanched potatoes is condensed with the filtered cleaning water and recycled again to achieve the purpose of water resource recycling; therefore, it has the advantage of improving the utilization rate of water resources.

[0086] It should be understood that the blanching assembly 4 is a conventional steam peeler, a separator-stator steam peeler, or the like, all of which have a housing cavity for placing potatoes. The heating element is a heater from a conventional steam peeler or a separator-stator steam peeler, and the blanching water inlet 40 is the water inlet of the heater. The steam outlet 41 is a steam outlet 41 provided on the housing of the steam peeler or separator-stator steam peeler. Those skilled in the art can select the type of blanching assembly 4 according to their needs.

[0087] It should be noted that the filter component 2 is located upstream of the heat exchange component 3. Therefore, when the cleaning water and steam are heat exchanged in the heat exchange component 3, there is no sand, soil, etc. in the cleaning water to absorb the heat of the steam. Therefore, this setting method also has the effect of complete heat exchange.

[0088] In the implementation method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the structure and setting of the cleaning component 1 are further explained below to make this solution clearer.

[0089] The cleaning assembly 1 includes a cleaning shell 11 with a accommodating space, and a cleaning part 10 arranged inside the cleaning shell 11 to clean the surface of potatoes. The upper end of the cleaning shell 11 has an openable cleaning cover 12, and the cleaning cover 12 is provided with a cleaning water inlet 14, and the lower end of the cleaning shell 11 has a cleaning drain port 15; and, a drain valve 13 is also provided at the cleaning drain port 15 of the cleaning assembly 1, and the drain valve 13 is used to control whether the cleaning assembly 1 drains the filter assembly 2. When the filter assembly 2 is blocked or the filtration speed is slow, the drain valve 13 can be closed to block the drainage path of the cleaning assembly 1 to the filter assembly 2, so that the filter assembly can be disassembled and repaired or wait for the filter assembly 2 to completely filter the cleaning water.

[0090] Specifically, the cleaning component 10 includes a vibrating screen plate 100, a brushing component 101 and a spraying component 102 arranged in the cleaning shell 11; in the vertical direction, the cleaning drain outlet 15 is opened on the bottom wall surface of the cleaning shell 11, and the vibrating screen plate 100 is horizontally arranged in the cleaning shell 11 for placing potatoes; the spraying component 102 is fixed on the side wall of the cleaning shell 11, located above the vibrating screen plate 100, and the nozzle 1021 of the spraying component 102 is downward facing the vibrating screen plate 100; the brushing component 101 is installed on the side wall of the cleaning shell 11, located between the spraying component 102 and the vibrating screen plate 100, and the brushing roller 1010 of the brushing component 101 is facing the vibrating screen plate 100 and can move above the vibrating screen plate 100 along the width direction of the cleaning shell 11.

[0091] More specifically, when the cleaning component 10 cleans the potatoes placed on the vibrating screen plate 100, the nozzle 1021 of the spraying component 102 sprays water toward the potatoes on the vibrating screen plate 100, and the brushing roller 1010 moves along the width direction of the cleaning shell 11 to brush the potatoes on the vibrating screen plate 100. At the same time, the vibrating screen plate 100 vibrates at a high frequency and the potatoes on the vibrating screen plate 100 roll on the vibrating screen plate 100.

[0092] More specifically, when cleaning potatoes, since the potatoes are dug out from the soil and have dirt, sand, and gravel attached to their surfaces, water is first sprayed onto the potatoes through the nozzle 1021 of the spraying member 102 during the cleaning process, thereby soaking the potatoes and loosening and falling off the dirt, sand, and gravel attached to the potato surfaces. The surfaces are then scrubbed by the scrubbing roller 1010 to clean them. The vibrating screen plate vibrates and rolls the potatoes placed thereon, so that the potato surfaces are completely cleaned.

[0093] More specifically, the cleaning component 1 is arranged above the filtering component 2, so that the cleaning water after washing the potatoes can be discharged from the cleaning component 1 to the filtering component 2 in a timely manner, ensuring the reliability of the system operation.

[0094] like Figure 1 and Figure 2 As shown, the structures and arrangements of the spraying member 102 , the brushing member 101 and the vibrating screen plate 100 are not limited.

[0095] In one feasible embodiment, the spraying component 102 includes a water extraction pipe 1020 mounted on the top outer wall of the cleaning shell 11 in a vertical direction, and a plurality of nozzles 1021 mounted on the top inner wall of the cleaning shell 11, and the water extraction pipe 1020 passes through the top wall of the cleaning shell 11 and is respectively connected to the plurality of nozzles 1021. The vibrating screen plate 100 includes a vibration motor 1001 and a screen plate 1002, the screen plate 1002 is parallel to the top wall of the cleaning shell 11, and the vibration motor 1001 is mounted on the inner wall of the cleaning shell 11. The vibration motor 1001 is connected to the screen plate 1002 and can drive the screen plate 1002 to vibrate, so that when potatoes are placed on the screen plate 1002, the vibration of the screen plate 1002 driven by the vibration motor 1001 can cause the potatoes to roll on the screen plate 1002. It should be understood that the number of the plurality of nozzles 1021 is not limited, for example, it can be set to 2, 5, 7, etc.

[0096] Specifically, a slide groove is opened on the side wall of the cleaning shell 11 along the width direction of the cleaning component 1; the brushing component 101 includes a brushing roller 1010, a sliding seat 1011 and a driving motor, wherein the sliding seat 1011 is slidingly connected to the slide groove; one end of the brushing roller 1010 is rotatably connected to the side wall of the sliding seat 1011, and the other end extends along the width direction of the cleaning component 1 and is located above the screen plate 1002, and the outer peripheral wall of the brushing roller 1010 is provided with bristles; the driving motor is installed on the side wall of the cleaning shell 11 and is transmission-connected to the sliding seat 1011, and is used to drive the sliding seat 1011 to slide in the slide groove.

[0097] More specifically, when cleaning dirt and gravel from the surface of potatoes, a water pump 1020 is connected to a water pump in a water supply tank. Water is pumped into the water pump 1020 and sprayed toward the potatoes through multiple nozzles 1021 to clean the potatoes. Simultaneously, a drive motor drives the sliding seat 1011 and drives the scrubbing roller 1010 to reciprocate, scrubbing the potato surface. Simultaneously, the vibration motor 1001 drives the sieve plate 1002 to vibrate, and the potatoes roll on the sieve plate 1002, completely cleaning the potato surface. Furthermore, because the potato surface is irregular, bristles are provided on the surface of the scrubbing roller 1010 so that the entire surface of the potato can be covered and scrubbed.

[0098] More specifically, since the scrubbing roller 1010 is located between the multiple nozzles 1021 and the sieve plate 1002, the spraying component 102 can also rinse the bristles on the surface of the scrubbing roller 1010 when spraying potatoes, avoiding the adhesion of dirt and sand to the bristles, thereby reducing the degree of scrubbing of the potato surface by the bristles, resulting in the problem of incomplete cleaning of the potatoes.

[0099] In the implementation method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the structure and setting of the filter component 2 are further explained below to make this solution clearer.

[0100] The filter assembly 2 includes a first filter component 21 and a second filter component 22 arranged in sequence along the flow direction of the cleaning water, and in the vertical direction, the first filter component 21 is arranged above the second filter component 22; wherein, the filter water inlet 26 is arranged at the upper end of the first filter component 21, the drain outlet of the filter assembly 2 is arranged at the lower end of the second filter component 22, and the lower end of the first filter component 21 and the upper end of the second filter component 22 are connected through a pipeline fluid.

[0101] Specifically, the filter element component 20 includes a first filter element 200 disposed horizontally within the first filter component 21, and a second filter element 201 disposed horizontally within the second filter component 22. The filter pores of the first filter element 200 are larger than those of the second filter element 201. Wash water from the wash drain outlet 15 flows into the first filter component 21 through the filter water inlet 26, is filtered by the first filter element 200, flows into the second filter component 22, and is filtered again by the second filter element 201 before entering the wash water channel 30 through the filter drain outlet 27.

[0102] More specifically, the filter pores of the first filter element 200 are larger than the filter pores of the second filter element 201; when the washing water for washing potatoes is filtered through the filter component 2, the first filter element 200 of the filter element component 20 is first used to filter out larger impurities in the washing water, such as sand and gravel; and then the second filter element 201 of the filter element component 20 is used to filter out smaller impurities in the washing water, such as soil; therefore, by setting up two-stage filtration, it is ensured that the washing water for washing potatoes can be completely filtered, and when it is then passed into the blanching component 4 for vaporization, the generation of impurities is reduced.

[0103] It should be understood that the first filter element 200 may be a filter plate with filter holes, or a filter element made of filter materials such as PP cotton, origami PP, non-woven fabric, scale inhibitor, activated carbon, etc., and this embodiment does not limit this. The second filter element may also be a filter plate with filter holes, or a filter element made of filter materials such as reverse osmosis membrane, nanofiltration membrane, etc., and this embodiment does not limit this.

[0104] The structure and arrangement of the first filter component 21 are not limited.

[0105] In a feasible embodiment, the first filter component 21 includes a filter box 211, and the filter box 211 of the first filter component 21 includes a water inlet chamber 2110 and a water outlet chamber 2111. In the vertical direction, the water inlet chamber 2110 is located above the water outlet chamber 2111, and the filter water inlet 26 is opened on the top wall surface of the water inlet chamber 2110. The first filter element 200 of the filter element component 20 is arranged between the water inlet chamber 2110 and the water outlet chamber 2111 and is fixedly and detachably connected to the inner wall surface of the filter box 211 of the first filter component 21. The drain outlet of the first filter component 21 is opened on the bottom wall surface of the water outlet chamber 2111, and the water outlet chamber 2111 is arranged in a "V" shape.

[0106] Specifically, the first filter component 21 is provided with a water inlet chamber 2110 and a water outlet chamber 2111. When the cleaning water of the potatoes after cleaning the cleaning component 1 is discharged to the filter component 2, it first enters the water inlet chamber 2110 of the first filter component 21, and then passes through the first filter element 200 of the filter core component 20 to filter out larger impurities before entering the water outlet chamber 2111; by providing the water inlet chamber 2110 and the water outlet chamber 2111, the cleaning water entering the first filter component 21 has a storage function, thereby avoiding the problem of cleaning water being retained in the cleaning component 1 due to the slow filtering speed of the first filter element 200 of the filter core component 20.

[0107] More specifically, the water outlet chamber 2111 is configured in a "V" shape, so that the cleaning water filtered by the first filter element 200 of the filter element component 20 can be quickly collected at the drain port of the first filter component 21 and discharged through the drain port of the first filter component 21. It should be understood that the "V" shape of the water outlet chamber 2111 is, in other words, funnel-shaped.

[0108] The structure and arrangement of the second filter component 22 are not limited.

[0109] In a feasible embodiment, the second filter component 22 includes a water filter box 221, and the water filter box 221 of the second filter component 22 includes a water inlet chamber 2210 and a drainage chamber 2211. In the vertical direction, the water inlet of the second filter component 22 is opened on the top wall of the water inlet chamber 2210, and the filter drainage outlet 27 is opened on the side wall of the drainage chamber 2211. The second filter element 201 of the filter element component 20 is arranged between the water inlet chamber 2210 and the drainage chamber 2211 and is fixedly and detachably connected to the inner wall surface of the water filter box 221 of the second filter component 22; and, the drainage outlet of the first filter component 21 is connected to the water inlet of the second filter component 22 through a first auxiliary pipeline 23, and a first drainage valve 24 is provided on the first auxiliary pipeline 23, and the filter drainage outlet 27 is also provided with a second drainage valve 25.

[0110] Specifically, the second filter component 22 is provided with a water inlet chamber 2210 and a water outlet chamber 2211. After the wash water filtered by the first filter element 200 enters the water inlet chamber 2210 through the first auxiliary pipeline 23, it passes through the second filter element 201 of the filter component 20 to remove small impurities before entering the water outlet chamber 2211 and finally being discharged from the water outlet chamber 2211. The provision of the water inlet chamber 2210 and the water outlet chamber 2211 serves to store the wash water entering the second filter component 22, thereby preventing the wash water from being retained in the first filter component 21 due to the slow water filtration rate of the second filter element 201 of the filter component 20. Furthermore, a first water outlet valve 24 provided on the first auxiliary pipeline 23 controls the water outlet rate from the first filter component 21 to the second filter component 22. If the second filter component 22 is unable to filter the wash water from the first filter component 21 in time, the first water outlet valve 24 can be closed to stop the water supply from the first filter component 21 to the second filter component 22. The filter drain port 27 is also provided with a second drain valve 25 . When the blanching component 4 is not working, the second drain valve 25 can be closed to control the filter component 2 to supply water to the cleaning water channel 30 .

[0111] In the implementation method disclosed in this embodiment, Figure 1 and Figure 2 As shown, the structure and setting of the heat exchange component 3 are further explained below to make this solution clearer.

[0112] The heat exchange component 3 includes a cleaning water channel 30 and a steam condensation channel 31. The cleaning water channel 30 extends from the filter drain outlet 27 to the blanching water inlet 40, and the steam condensation channel 31 extends from the steam outlet 41 to the blanching water inlet 40, and partially bends and extends through the inside of the cleaning water channel 30.

[0113] Specifically, the wash water channel 30 includes a heat exchange tank 301 disposed within a connecting pipe 300, connecting the filter drain outlet 27 and the blanching water inlet 40. The central portion of the steam condensation channel 31 is spirally curved and passes through the heat exchange tank 301, thereby increasing the steam condensation distance and area, thereby ensuring complete steam condensation. The downstream portion of the wash water channel 30 and the downstream portion of the steam condensation channel 31 are combined into a mixing pipe 32, the downstream end of which is connected to the blanching water inlet 40. This ensures that the temperature of the mixed wash water and condensed water remains consistent, facilitating heating and vaporization of the blanching component 4, resulting in rapid and complete vaporization.

[0114] More specifically, when both the filter assembly 2 and the blanching assembly 4 are operating, the rinse water filtered by the filter assembly 2 enters the heat exchange tank 301 through the connecting pipe 300. Simultaneously, the steam from blanching the potatoes in the blanching assembly 4 enters the steam condensation channel 31. As the steam passes through the middle of the steam condensation channel 31, it exchanges heat with the rinse water in the heat exchange tank 301 and is condensed into condensed water. Furthermore, the rinse water and condensed water flow through the mixing pipe 32, through the blanching water inlet 40, and into the blanching assembly 4, where they are vaporized again for recycling, reducing water waste.

[0115] More specifically, a first booster pump 34 is provided in the cleaning water channel 30 upstream of the heat exchange tank 301, and a second booster pump 35 is provided in the mixing pipeline 32; the water flow discharged from the filter component 2 into the pipeline can be pressurized by the first booster pump 34, and the water flow discharged from the heat exchange tank 301 to the mixing pipeline 32 can be pressurized by the second booster pump 35; thereby avoiding the problem of backflow of water in the pipeline.

[0116] More specifically, according to the potato skin pretreatment system provided by the embodiment of the present invention, since non-condensable gas will be generated after the steam is condensed into condensed water, a condensate tank 33 is also provided in the downstream part of the steam condensation channel 31, and in the vertical direction, the condensate tank 33 is located below the heat exchange tank 301, and the condensate tank 33 is arranged in the steam condensation channel 31 downstream of the pipeline part passing through the heat exchange tank 301, and is located upstream of the mixing pipeline 32; and in the vertical direction, a non-condensable gas exhaust port 330 is opened on the top wall surface of the condensate tank 33, and a non-condensable gas discharge valve 331 and a non-condensable gas fan are provided at the non-condensable gas exhaust port 330.

[0117] It is important to understand that non-condensable gases are gases that cannot be liquefied in a condensing device under certain temperature and pressure conditions. Common non-condensable gases include nitrogen, methane, carbon monoxide, hydrogen, and other alkanes.

[0118] Therefore, setting up the condensation water tank 33 can, on the one hand, quickly collect the condensation water; on the other hand, after the non-condensable gas enters the condensation water tank 33, the non-condensable steam discharge valve can be opened to discharge the non-condensable gas; and, by setting up a non-condensable gas fan, the discharge speed of the non-condensable gas can be accelerated, thereby preventing the non-condensable gas from entering the blanching component 4 again, thereby ensuring the quality of the steam generated by the blanching component 4, and further improving the blanching effect of the steam component 4 on potatoes.

[0119] More specifically, according to the potato blanching pretreatment system provided by the embodiment of the present invention, an exhaust gas treatment device 6 and a negative pressure pump 5 are provided upstream of the pipeline portion in the steam condensation channel 31 that passes through the heat exchange tank 301, which are arranged in sequence along the steam conveying direction; since a large amount of steam is generated during the blanching process of potatoes, the steam after blanching needs to be quickly discharged, therefore, the negative pressure pump 5 is provided in the steam condensation channel 31 so that the steam after blanching can be quickly drawn out into the steam condensation channel 31 by the negative pressure pump 5.

[0120] Furthermore, during the scalding process, the steam needs to be discharged quickly after scalding, so the negative pressure pump 5 will give the steam negative pressure, so that the steam will carry a small amount of potato peels and mud and sand remaining on the potato peels during the discharge process. Therefore, by setting up the exhaust steam treatment device 6, the steam entering the steam condensation channel 31 can be purified to prevent the potato peels and mud and sand it carries from contaminating the condensed water.

[0121] More specifically, the structure and arrangement of the exhaust gas treatment device 6 are not limited, and it can be, for example, a centrifugal separator, an impact separator, a water washing tower separator, a cyclone separator, etc.
