Description

Technical Field

[0001] The utility model belongs to the technical field of potato processing, in particular to a steam separation device of potato peeling equipment. Background Art

[0002] The industrial production of potato products involves multiple processing steps. For example, the process of turning potato raw materials into French fries generally includes washing, peeling, blanching, drying, frying, and bagging. These steps require a large amount of steam to process or treat the product. In particular, the peeling step uses high-temperature, high-pressure steam to heat and peel the washed potato raw materials. This heated steam is then recovered and reused in subsequent processes, improving steam utilization and ultimately saving costs and reducing energy consumption.

[0003] Taking potato processing as an example, in order to achieve secondary recovery of high-temperature and high-pressure exhaust gas emitted from the potato peeling process, the prior art provides a system for purifying peeling waste gas. For example, patent publication number CN215819845U discloses a waste gas recovery system for the peeling process of potato products processing. The system purifies the waste gas and separates the waste gas from the waste by setting an expansion tank and a waste gas purification device between the high-pressure exhaust gas outlet of the peeling machine and the heat exchange device (or other equipment for collecting the decompressed and purified waste gas). This system purifies the waste gas and separates the waste gas from the waste, thereby achieving the effect of purifying the peeling waste gas for recycling. However, the above scheme uses the expansion tank and the waste gas purification device to separate the waste gas from the waste, and the separated waste is directly discharged through the waste discharge port. In fact, the waste gas discharged from the high-pressure exhaust gas outlet of the peeling machine is mixed with a large amount of potato peels, soluble starch, etc., which will cause a large amount of usable substances to be lost and wasted during the potato production process. Utility Model Content

[0005] In order to solve the above technical problems, an embodiment of the present utility model discloses a steam separation device for a potato peeling device, the potato peeling device includes a high-pressure peeling tank and a steam exhaust channel connected to the high-pressure peeling tank at one end, the steam exhaust channel is used to discharge the high-pressure exhaust gas of the high-pressure peeling tank; the steam separation device is connected to the other end of the steam exhaust channel, the steam separation device includes a condensation component, a primary separation component and a secondary separation component arranged in sequence along the steam flow direction.

[0008] The secondary separation component includes a secondary separation chamber and a distillation component arranged in the secondary separation chamber. The upper end of the secondary separation chamber is provided with a second feed port connected to the mixed liquid channel, and the top of the secondary separation chamber is provided with an air outlet. The distillation component distills the mixed liquid in the secondary separation chamber, and a starch collection part is formed at the bottom of the secondary separation chamber.

[0009] Using the above technical solution, the high-pressure exhaust gas from the high-pressure peeling tank of the potato peeling equipment is discharged through a steam exhaust channel connected to the high-pressure peeling tank. A steam separation device is connected to the other end of the steam exhaust channel, thereby conveying the high-pressure exhaust gas to the steam separation device. Within the steam separation device, the high-pressure exhaust gas, which is mixed with a large amount of potato peels and soluble starch, is separated and recyclable substances are extracted. The steam separation device includes a condensation assembly, a primary separation assembly, and a secondary separation assembly, which are arranged in sequence along the direction of steam flow. The condensation assembly condenses the high-pressure exhaust gas discharged from the potato peeling equipment, converting the steam into condensed water. The primary separation assembly performs a first solid-liquid separation on the condensed water after condensation by the condensation assembly, aiming to separate solid impurities such as potato peels and mud and sand from the condensed water. The secondary separation assembly performs a second separation on the mixed liquid filtered by the primary separation assembly, separating the starch dissolved in the mixed liquid. The separated starch can be recycled to avoid waste.

[0010] In addition, the high-pressure exhaust gas exchanges heat with the coolant at the heat exchange component of the condensing component, and the temperature of the high-pressure exhaust gas is reduced and converted into condensed water. The filter component of the primary separation component can intercept solid debris in the mixed liquid, so that the solid debris remains on one side of the filter component, while allowing the starch mixture to flow to the mixed liquid channel on the other side of the filter component. The distillation component of the secondary separation component distills the starch mixture entering the secondary separation chamber, causing the starch in the mixture to separate and be concentrated in the starch collection part, thereby separating the usable substances in the high-pressure exhaust gas generated by potato peeling. The separated starch can be recycled to avoid waste. In addition, the distillation process also purifies the water in the mixed liquid for a second time, which can be used for other subsequent processing steps.

[0011] According to another specific embodiment of the present invention, the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the distillation component includes a heating net and a plurality of heating rods, the heating net is arranged in the secondary separation chamber and below the second feed port, and is used to disperse and heat the mixed liquid flowing in from the second feed port, the plurality of heating rods are arranged below the heating net, and the outer wall surfaces of the plurality of heating rods are respectively arranged opposite to the bottom wall of the starch collecting part, so as to heat the mixed liquid flowing from the heating net to the starch collecting part.

[0012] By adopting the above technical solution, the heating net has multiple pores and a heating function, which can disperse the starch mixture in contact with it, increase the contact area with the mixture and heat the mixture; the preliminarily heated mixture continues to flow through the pores of the heating net to the starch collection part at the bottom of the secondary separation chamber, and multiple heating rods can continue to heat the mixture, separate the starch from the mixture, and convert the water into water vapor and separate it from the mixture, thereby realizing the separation and collection of starch.

[0013] According to another specific embodiment of the present invention, in the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, a plurality of heating nets are arranged in parallel at intervals in the height direction of the secondary separation chamber, and the outer periphery of each heating net is connected to the inner peripheral wall of the secondary separation chamber and is arranged inclined relative to the horizontal direction.

[0014] The above technical solution, through the installation of multiple heating nets, ensures that the mixed liquid is heated relatively evenly at different levels within the secondary separation chamber, accelerating the vaporization of water in the mixed liquid. The heating nets are tilted relative to the horizontal to increase the contact area between the mixed liquid and the heating nets, helping to improve heating efficiency and facilitate the guidance of the mixed liquid to the starch collection area at the bottom of the secondary separation chamber.

[0015] According to another specific embodiment of the present invention, in the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, multiple heating rods are arranged in pairs on the bottom wall of the starch collecting part and are evenly spaced along the circumference of the bottom wall of the starch collecting part.

[0016] The above technical solution accelerates the distillation efficiency of the mixed liquid by using multiple heating rods. Arranging the heating rods in pairs helps achieve a more uniform heating effect. Furthermore, arranging the heating rods evenly around the bottom wall of the starch collection portion ensures that the entire bottom wall of the starch collection portion is covered by the heating rods, thereby evenly heating the mixed liquid.

[0017] According to another specific embodiment of the present invention, the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention has a starch collecting part in the shape of a bucket with a narrowed lower end, and a second discharge channel is formed at the lower end of the starch collecting part, and the second discharge channel is connected to the starch collection bin arranged outside the secondary separation chamber.

[0018] Using this technical solution, the starch collection section takes on a bucket-shaped shape with a tapered lower end, allowing starch to converge toward the bottom during the collection process. As the distillation process progresses, starch gradually accumulates in the starch collection section. The bucket-shaped structure guides the starch toward the lower end, improving starch collection efficiency. The separated starch can flow smoothly through a second discharge channel formed at the lower end of the starch collection section and directly into a starch collection bin specifically designed for storage, allowing it to be recycled.

[0019] According to another specific embodiment of the present invention, the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the filtering component includes a plurality of filter screens spaced and arranged in parallel along the height direction of the first-level separation chamber, the outer peripheral edge of each filter screen abuts the inner peripheral wall of the first-level separation chamber and is inclined relative to the horizontal direction, wherein, in the height direction of the first-level separation chamber, the lowest part of each filter screen is aligned with the first feed port of the first-level separation chamber; and a plurality of first discharge channels arranged along the height direction of the first-level separation chamber are provided on the side wall of the first-level separation chamber, each first discharge channel is located at the corresponding position of the lowest part of the corresponding filter screen in the height direction of the first-level separation chamber, and each first discharge channel is connected to the solid collection component.

[0020] By adopting the above technical solution, multiple filter screens are arranged in parallel and spaced apart in the height direction of the primary separation chamber, so that the condensed water flowing from the first feed inlet to the mixed liquid channel can be filtered multiple times, thereby improving the filtration efficiency. Because the water pressure from the condensation assembly is generally high, the condensed water from the first feed inlet of the primary separation chamber usually reaches the side away from the first feed inlet under high pressure. The filter screens are arranged so that the outer peripheral edge of each filter screen abuts the inner peripheral wall of the primary separation chamber and is inclined relative to the horizontal direction. In the height direction of the primary separation chamber, the lowest point of each filter screen is aligned with the first feed inlet of the primary separation chamber. This can maximize the area of ​​​​the filter screen to filter the condensed water and facilitate the flow of the filtered mixed liquid along the inclined direction. Each filter screen is provided with a first discharge channel at the corresponding position of the lowest point in the height direction of the primary separation chamber, and each first discharge channel is connected to the solid collection component, so that solid debris filtered by the filter screen, such as potato peels, mud and sand, can be discharged to the solid collection component for unified collection and treatment.

[0021] According to another specific embodiment of the present invention, in the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the height directions of the primary separation chamber and the secondary separation chamber are both parallel to the vertical direction.

[0022] By adopting the above technical solution, the height direction of the first-level separation chamber is parallel to the vertical direction, so that the condensed water entering the first-level separation chamber from the first feed port naturally flows downward to the filter net for filtration under the action of gravity, which can effectively improve the filtration efficiency; the height direction of the second-level separation chamber is parallel to the vertical direction, so that the mixed liquid entering the second-level separation chamber from the second feed port naturally flows downward to the heating net for heating under the action of gravity, and continues to flow downward to the starch collection part at the bottom of the second-level separation chamber.

[0023] According to another specific embodiment of the present invention, the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the filter component also includes a scraper plate movably arranged above each filter screen and away from the side of the first discharge channel, the extension direction of each scraper plate is perpendicular to the inclination direction of the filter screen and the lower end is in sliding contact with the upper surface of the corresponding filter screen, which is used to scrape the solid debris filtered by the filter screen from the filter screen and discharge it from the first discharge channel to the solid collection component.

[0024] By adopting the above technical solution, a scraper plate is movably arranged above each filter screen and away from the side of the first discharge channel. The extension direction of the scraper plate is perpendicular to the inclination direction of the filter screen, so that the scraper plate can slide back and forth along the inclination direction of the filter screen, and can fully cover the upper surface of the filter screen during the sliding process; the lower end of the scraper plate slides and abuts against the upper surface of the corresponding filter screen to ensure close contact between the scraper plate and the filter screen, and can scrape off solid debris such as potato peels attached to the filter screen and discharge them from the first discharge channel.

[0025] According to another specific embodiment of the present invention, the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the heat exchange component includes an air flow pipe and a cooling liquid pipe arranged at intervals from each other, the air flow pipe extends along the height direction of the cooling chamber, one end is connected to the other end of the steam inlet channel, and the other end is toward the condensate channel, and both ends of the cooling liquid pipe are connected to the cooling liquid container outside the cooling chamber.

[0026] With this technical solution, high-pressure exhaust gas introduced by the steam inlet channel passes through the airflow duct extending along the height of the cooling chamber. Heat is transferred from the steam to the coolant in the adjacent coolant duct through the duct wall, thereby transferring heat from the steam to the coolant. Condensed water adheres to the duct and then flows along the duct wall to the condensate channel located below the heat exchange component. Both ends of the coolant duct are connected to a coolant container outside the cooling chamber, allowing the coolant to circulate between the container and the coolant duct in the cooling chamber.

[0027] According to another specific embodiment of the present invention, in the steam separation device of the potato peeling equipment disclosed in the embodiment of the present invention, the height direction of the cooling chamber is parallel to the vertical direction, and the cooling liquid pipeline is arranged to cover the outer periphery of each air flow pipeline.

[0028] With this technical solution, the height of the cooling chamber is parallel to the vertical direction. As the high-pressure exhaust gas entering the cooling chamber condenses in the heat exchange component, the condensed water on the airflow duct walls flows vertically downward to the condensate channel. By wrapping the coolant duct around the periphery of each airflow duct, the heat exchange area is increased, improving heat exchange efficiency and fully cooling the steam flowing through the duct.

[0029] The beneficial effects of the utility model are:

[0030] The utility model provides a steam separation device for a potato peeling device. High-pressure exhaust gas from the high-pressure peeling tank of the potato peeling device is discharged from a steam exhaust channel connected to the high-pressure peeling tank. The steam separation device is connected to the other end of the steam exhaust channel, thereby conveying the high-pressure exhaust gas to the steam separation device.

The steam separation device includes a condensation component, a primary separation component, and a secondary separation component, which are arranged in sequence along the direction of steam flow. The condensation component condenses the high-pressure exhaust gas discharged from the potato peeling device, converting the steam into condensed water.

The separated starch can be recycled to avoid waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] During the potato peeling process, high-pressure steam is used to scald the potato skins. The high-pressure exhaust gas generated during this process contains not only water vapor but also a large amount of contaminants such as potato peels, soluble starch, silt, potato starch, and non-condensable gases. Among these contaminants, soluble starch and other organic matter have high recycling value. When the exhaust gas passes through an expansion tank for decompression and initial contamination removal, some larger contaminants such as potato peels and silt are separated. However, since the exhaust gas still contains a large number of tiny particles such as potato peel fragments and soluble starch, these particles may not be completely captured when passing through the exhaust gas purification device, resulting in some usable substances being discharged along with the exhaust gas. Discharging exhaust gas containing a large amount of usable substances directly through the waste outlet not only wastes these valuable resources but also may pollute the environment. In particular, when the exhaust gas contains high concentrations of organic matter, direct discharge may lead to environmental problems such as eutrophication and soil contamination.

[0043] Based on the above problems, the utility model provides a steam separation device for potato peeling equipment. By arranging a condensation component, a primary separation component and a secondary separation component in sequence along the direction of steam flow, the high-pressure exhaust gas after potato peeling is condensed and separated twice, and recyclable starch and other substances are extracted therefrom, so as to solve the problem in the prior art that the exhaust gas discharged from the high-pressure exhaust gas outlet of the potato peeler is mixed with a large amount of potato peels, soluble starch, etc., resulting in the loss and waste of a large amount of usable substances in the potato production process.

[0044] In order to make the purpose, technical solutions and advantages of the present invention clearer, the steam separation device of the potato peeling device of the present invention will be described in detail below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the potato peeling equipment 1 includes a high-pressure peeling tank 10 and a steam exhaust channel 11 connected to the high-pressure peeling tank 10 at one end. The steam exhaust channel 11 is used to discharge the high-pressure exhaust gas of the high-pressure peeling tank 10. The high-temperature and high-pressure steam in the high-pressure peeling tank 10 of the potato peeling equipment 1 is used to peel the potatoes. The high-pressure exhaust gas after peeling is discharged from the steam exhaust channel 11 connected to the high-pressure peeling tank 10. In order to purify and separate the discharged steam and extract recyclable substances therein, the steam separation device 2 is connected to the other end of the steam exhaust channel 11, and the steam separation device 2 is used to purify and separate the high-pressure exhaust gas and extract recyclable substances therein, such as soluble starch.

[0046] It should be understood that the high-pressure exhaust gas in the present invention refers to the gas mixture generated in the high-pressure peeling tank and released during the potato peeling process. The gas mixture mainly consists of water vapor, air, and other organic matter such as soluble starch, potato peel fragments, tiny particles, etc. released from the potatoes.

[0047] The structure of the steam separation device 2 will be generally described below.

[0048] like Figure 1 As shown, the steam separation device 2 provided in the specific embodiment of the present invention includes a condensation component 20, a primary separation component 21 and a secondary separation component 22 arranged in sequence along the steam flow direction. The steam flow direction refers to the direction in which the high-temperature and high-pressure steam in the high-pressure peeling tank 10 is discharged from the steam discharge channel 11 and flows to the steam separation device 2. For example, Figure 1 In the display, it is shown as horizontal direction ( Figure 1 The direction parallel to the X direction in the diagram). Among them, the high-pressure exhaust gas discharged from the potato peeling equipment 1 is condensed by the condensation component 20 to realize the conversion of steam into condensed water. The condensed water after condensation by the condensation component 20 can be subjected to a first solid-liquid separation by the primary separation component 21, the purpose of which is to separate the solid impurities in the condensed water, such as potato peels, mud and sand, by filtering. The mixed liquid filtered by the primary separation component 21 can be subjected to a second separation by the secondary separation component 22, thereby separating the starch dissolved in the mixed liquid. The separated starch can be recycled, for example, it can be used in other processing steps or sold to avoid waste. In addition, the secondary separation component 22 can also separate the water in the mixed liquid, convert the water into water vapor and discharge it, which can be used in other subsequent processing steps.

[0049] The structure of the condensation assembly 20 is not limited. In one embodiment of the present invention, the condensation assembly 20 includes a cooling chamber 201. The cooling chamber 201 serves as the primary location for the entire condensation process, providing a closed spatial environment for steam condensation, allowing the steam to fully interact with the heat exchange component 204 to achieve a state transition. It is understood that the condensation assembly 20 can be a closed tank, with the cooling chamber 201 formed within the closed tank.

[0050] Furthermore, the cooling chamber 201 is provided with a steam inlet channel 202 at its upper end and a condensate channel 203 at its lower end. One end of the steam inlet channel 202 is connected to the other end of the steam exhaust channel 11 of the potato peeling device 1, allowing the high-pressure exhaust gas generated by the potato peeling device 1 to be smoothly introduced into the cooling chamber 201. The other end of the steam inlet channel 202 faces the heat exchange component 204 within the cooling chamber 201, ensuring that the introduced steam can effectively contact the heat exchange component 204, thereby exchanging heat and achieving condensation. The heat exchange component 204 is located between the steam inlet channel 202 and the condensate channel 203. By exchanging heat with the steam, the steam temperature is reduced and converted into condensate. The condensate channel 203 is provided below the heat exchange component 204 to collect the condensate discharged by the heat exchange component 204 for subsequent separation operations. It is understandable that the condensed water channel 203 can be a pipe with one end connected to the heat exchange component 204, or a groove-shaped structure with an opening toward the heat exchange component 204, as long as it can collect the condensed water discharged from the heat exchange component 204.

[0051] It should be noted that the heat exchange component 204 can specifically be a shell and tube heat exchanger, a spiral plate heat exchanger, a bellows heat exchanger, or the like, which utilizes the temperature difference between low-temperature liquid and high-temperature steam to achieve heat exchange.

[0052] In one specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the heat exchange component 204 includes an air flow pipe 2041 and a coolant pipe 2042 that are spaced apart from each other. It should be noted that, in order to facilitate intuitive display of the air flow pipe 2041, Figure 2 While coolant pipe 2042 is not shown, those skilled in the art will appreciate that coolant pipe 2042 can be a channel separated from airflow pipe 2041 by a pipe wall and connected to a coolant container at both ends, allowing the coolant to exchange heat with the steam in the adjacent airflow pipe 2041. Airflow pipe 2041 extends along the height of cooling chamber 201, with one end connected to the other end of steam inlet channel 202 and the other end facing condensate channel 203. The spaced arrangement of airflow pipe 2041 and coolant pipe 2042 creates conditions for steam condensation. As high-pressure exhaust gas introduced by steam inlet channel 2041 passes through airflow pipe 2041 extending along the height of cooling chamber 201, its heat can be transferred through the wall of airflow pipe 2041 to the coolant in the adjacent coolant pipe 2042, thereby achieving heat transfer from steam to coolant. Condensate condenses and adheres to airflow pipe 2041, then flows along the wall of airflow pipe 2041 to the condensate channel 203 disposed below heat exchange component 204. The height direction and vertical direction of the cooling chamber 201 ( Figure 1When the high-pressure exhaust gas entering the cooling chamber 201 is condensed in the heat exchange component 204, the condensed water condensed on the wall of the air flow duct 2041 flows downward in the vertical direction to the condensed water channel 203 under the action of gravity.

[0053] Both ends of the cooling liquid pipe 2042 are connected to the cooling liquid container ( Figure 2 The cooling liquid is connected to the cooling liquid container (not shown) so that the coolant can circulate between the coolant container and the coolant pipe 2042 of the cooling chamber 201. After the heat of the steam is transferred to the coolant in the coolant pipe 2042, the coolant that has absorbed the heat can flow back to the coolant container for heat dissipation or other processing. Then, new coolant can flow from the coolant container into the coolant pipe 2042 to continue participating in heat exchange with the steam, thereby continuously providing cooling for the condensation of the steam. The coolant pipe 2042 can be configured to cover the outer periphery of each airflow pipe 2041, thereby increasing the heat exchange area, improving the heat exchange efficiency, and fully cooling the steam flowing through the airflow pipe 2041.

[0054] It should be noted that if Figure 1 and Figure 2 As shown, the air flow channel 2041 is a plurality of channels arranged at intervals, and both ends of each channel are connected to the cooling chamber 201. The coolant channel 2042 is a channel that is arranged on the periphery of each air flow channel 2041 and is connected to the coolant container. The air flow channel 2041 and the coolant channel 2042 are separated by a channel wall. The two ends of the coolant channel 2042 can be Figure 1 and Figure 2 The left and right ends of the paper shown in Figure 1 and Figure 2 As long as the coolant can flow from one end of the coolant pipe 2042 to the other end for heat exchange, the condensation efficiency of the steam passing through the air flow pipe 2041 can be improved.

[0055] The structure of the primary separation assembly 21 is not limited. In one embodiment of the present invention, the primary separation assembly 21 includes a primary separation chamber 211. A first feed port 212 communicating with the condensate channel 203 is provided at the upper end of the primary separation chamber 211. The first feed port 212 can smoothly introduce condensate containing solid debris such as potato peels into the primary separation chamber 211. It is understood that the primary separation assembly 21 can be a closed tank, with the primary separation chamber 211 formed within the closed tank.

[0056] Furthermore, a filter element 214 is provided within the primary separation chamber 211, located between the first feed port 212 and the mixed liquid channel 213. Through its filtering function, it effectively intercepts solid debris in the mixed liquid, retaining it on one side of the filter element 214 while allowing the starch mixed liquid to flow toward the mixed liquid channel 213 on the other side of the filter element 214. Furthermore, a first discharge channel 215 is provided on the sidewall of the primary separation chamber 211, corresponding to one end of the filter element 214. Solid debris, such as potato peels, intercepted by the filter element 214 is discharged through the first discharge channel 215 and transported to the external solid collection element 3. A mixed liquid channel 213 is provided at the lower end of the primary separation chamber 211 to collect the starch mixed liquid filtered by the filter element 214, facilitating subsequent separation operations. It is understandable that the mixed liquid channel 213 can be a pipe with one end connected to the filter component 214, or a groove-shaped structure with an opening toward the filter component 214, as long as it can collect the mixed liquid filtered by the filter component 214.

[0057] The structure of the filter component 214 is not limited. For example, the filter component 214 can be a filter mesh, screen, cartridge filter, centrifugal solid-liquid separator, or sedimentation tank, etc., which can achieve solid-liquid separation. Specifically, when the filter component 214 is a filter mesh, screen, or cartridge filter, multiple filter components can be provided and arranged horizontally. As long as one side of the filter component 214 faces the first feed inlet 212 and the other side faces the mixed liquid channel 213, the filter component 214 can achieve solid-liquid separation of the condensed water flowing from the first feed inlet 212 to the mixed liquid channel 213.

[0058] In one specific embodiment of the present invention, Figure 1 As shown, the filter component 214 includes a plurality of filter screens 2141 spaced apart and arranged in parallel along the height direction of the primary separation chamber 211, which can filter the condensed water flowing from the first feed port 212 to the mixed liquid channel 213 multiple times to improve the filtering efficiency. Since the water pressure from the condensation component 20 is usually high, the condensed water from the first feed port 212 of the primary separation chamber 211 usually reaches the side away from the first feed port 212 under high pressure. The filter screens 2141 are arranged so that the outer periphery of each filter screen 2141 abuts against the inner peripheral wall of the primary separation chamber 211 and relative to the horizontal direction ( Figure 1The first-stage separation chamber 211 is tilted (in the X-direction). The lowest point of each filter screen 2141 is aligned with the first feed inlet 212 of the first-stage separation chamber 211 in the height direction of the first-stage separation chamber 211. This maximizes the area of ​​the filter screen 2141 used to filter the condensed water and facilitates the flow of the filtered mixed liquid along the tilted direction. Furthermore, the sidewalls of the first-stage separation chamber 211 are provided with a plurality of first discharge channels 215 arranged along its height direction. Each first discharge channel 215 is located at the lowest point of the corresponding filter screen 2141 in the height direction of the first-stage separation chamber 211. Each first discharge channel 215 is connected to the solids collection component 3, facilitating the discharge of solid debris filtered by the filter screen 2141, such as potato peels and mud and sand, into the solids collection component 3 for unified collection and processing.

[0059] It should be noted that the specific number of the multiple filter screens 2141 can be set to two, three, four, etc., and the specific number of the corresponding first discharge channels 215 can be set to two, three, four, etc. The more the number of filter screens 2141, the better the separation effect of solid debris. Those skilled in the art can make reasonable choices according to their needs, such as Figure 1 As shown, the number of the filter screens 2141 in this embodiment is preferably three.

[0060] It should be noted that the tilt angle of the filter 2141 can be 15°, 30°, 45°, etc., but the angle should not be too large. Those skilled in the art can reasonably set it according to actual conditions, as long as it can facilitate the filtered mixed liquid to flow along the tilt direction and prevent the filtered solid debris from falling off.

[0061] In one specific embodiment of the present invention, Figure 1 As shown, the filter component 214 further includes a scraper plate 2142 movably disposed above each filter screen 2141, away from the first discharge channel 215. Each scraper plate 2142 extends perpendicular to the inclination of the filter screen 2141, and its lower end slides against the upper surface of the corresponding filter screen 2141. In other words, the scraper plate 2142 can slide back and forth along the inclination of the filter screen 2141, fully covering the upper surface of the filter screen 2141 during the sliding process. The sliding contact between the lower end of the scraper plate 2142 and the upper surface of the corresponding filter screen 2141 ensures close contact between the scraper plate 2142 and the filter screen 2141, thereby scraping off solid debris such as potato peels attached to the filter screen 2141 and discharging it from the first discharge channel 215 to the solid collection component 3.

[0062] It should be noted that a driving mechanism is provided on one side of the scraper plate 2142, and the driving mechanism is used to drive the scraper plate 2142 to slide back and forth along the inclination direction of the filter screen 2141. The driving mechanism can be a common driving mechanism such as a gear rack mechanism, a belt drive mechanism, etc. For example, when it is set as a belt drive mechanism, a driving motor and a belt are provided, and the scraper plate 2142 is fixedly provided at one end of the belt. The driving motor can drive the belt to move back and forth, thereby driving the scraper plate 2142 to slide back and forth along the inclination direction of the filter screen 2141. Those skilled in the art can set and select according to actual needs, and this embodiment will not go into details.

[0063] It should be noted that the extension direction of the scraper plate 2142 is Figure 1 The direction perpendicular to the paper surface and the tilt direction of the filter 2141 refer to the direction relative to the horizontal direction ( Figure 1 The X direction in the figure) is tilted in the direction of Figure 1 After the middle filter 2141 is tilted, its lowest point is located on the left side relative to the highest point in the figure. The filter 2141 can also be tilted so that its lowest point is located on the right side relative to the highest point in the figure.

[0064] The structure of the secondary separation component 22 is not limited. In one embodiment of the present invention, the secondary separation component 22 includes a secondary separation chamber 221. The height direction of the primary separation chamber 211 and the secondary separation chamber 221 is parallel to the vertical direction ( Figure 1 The Y direction in the figure) is used to facilitate the condensed water entering the primary separation chamber 211 and flowing naturally downward to the filter screen 2141 for filtration under the action of gravity, which can effectively improve the filtration efficiency. The mixed liquid entering the secondary separation chamber 221 flows naturally downward to the heating screen 2231 for heating under the action of gravity, and continues to flow downward to the starch collection part 225 at the bottom of the secondary separation chamber 221. The upper end of the secondary separation chamber 221 is provided with a second feed port 222 connected to the mixed liquid channel 213, and the second feed port 222 introduces the mixed liquid filtered by the primary separation component 21 into the secondary separation chamber 221. It can be understood that the secondary separation component 22 can be a closed tank body, and the secondary separation chamber 221 is formed inside the closed tank body.

[0065] The distillation component 223 is disposed in the secondary separation chamber 221, and performs a distillation process on the mixed liquid entering the secondary separation chamber 221, and utilizes the different boiling points of each component to promote the separation of starch in the mixed liquid. An air outlet 224 is provided at the top of the secondary separation chamber 221, and the high-temperature steam generated during the distillation process is discharged from the air outlet 224 provided at the top of the secondary separation chamber 221. In addition, a starch collection portion 225 is formed at the bottom of the secondary separation chamber 221, and the starch separated from the mixed liquid after the distillation process is centrally stored in the starch collection portion 225. The distillation process also performs a second purification on the mixed liquid, which can be used for other subsequent processing steps.

[0066] The structure of the distillation component 223 is not limited. Specifically, the distillation component 223 can be a heating coil, a heating net, a heating rod, or the like, which can heat the starch mixture mixed with soluble starch by electric heating.

[0067] In one specific embodiment of the present invention, Figure 1 As shown, the distillation component 223 includes a heating net 2231 and a plurality of heating rods 2232. The heating net 2231 is arranged in the secondary separation chamber 221 and below the second feed port 222, and is used to disperse and heat the mixed liquid flowing in from the second feed port 222. After the mixed liquid enters the secondary separation chamber 221 through the second feed port 222, it flows downward to the heating net 2231 under the action of gravity. The heating net 2231 has multiple pores and a heating function, which can disperse the starch mixed liquid in contact with it, increase the contact area with the mixed liquid and heat the mixed liquid for the first time. A plurality of heating rods 2232 are arranged below the heating net 2231, and the outer wall surfaces of the plurality of heating rods 2232 are respectively arranged opposite to the bottom wall of the starch collection part 225, heating the mixed liquid flowing from the heating net 2231 to the starch collection part 225. The initially heated mixed liquid passes through the pores of the heating net 2231 and continues to flow to the starch collection part 225 at the bottom of the secondary separation chamber 221. The mixed liquid contacts the plurality of heating rods 2232 and evaporates due to the heat. Taking advantage of the fact that the boiling point of water is lower than that of starch, the mixed liquid is heated to near the boiling point of water, so that the water is converted into water vapor and separated from the mixed liquid. In this way, as the water vapor continues to escape, the relative content of starch in the components remaining in the starch collection part 225 will gradually increase, thereby achieving the separation and collection of starch. The separated water vapor is discharged from the air outlet 224.

[0068] It should be noted that the specific number of the multiple heating rods 2232 can be set to two, four, eight, etc. The more heating rods 2232 there are, the larger the contact area between the heating rods 2232 and the mixed liquid, and the higher the heating efficiency. Technical personnel in this field can make reasonable choices according to needs, as long as the mixed liquid can be efficiently heated and the starch can be separated.

[0069] In one specific embodiment of the present invention, Figure 1 As shown, multiple heating nets 2231 are spaced parallel to each other along the height of the secondary separation chamber 221. The presence of multiple heating nets 2231 allows the mixed liquid to be heated relatively evenly at different height levels within the secondary separation chamber 221, accelerating the vaporization rate of the water in the mixed liquid. The outer periphery of each heating net 2231 is connected to the inner circumferential wall of the secondary separation chamber 221 and is tilted relative to the horizontal. This arrangement increases the contact area between the mixed liquid and the heating net 2231, helping to improve heating efficiency and facilitates the guidance of the mixed liquid to the starch collection portion 225 at the bottom of the secondary separation chamber 221.

[0070] It should be noted that the specific number of the multiple heating nets 2231 can be set to two, three, four, etc. The more the number of heating nets 2231, the higher the heating efficiency. Those skilled in the art can make reasonable choices according to their needs, as long as the mixed liquid can be efficiently heated. Figure 1 As shown, the number of heating nets 2231 in this embodiment is preferably three. Figure 1 After the middle heating net 2231 is tilted, its lowest point is located on the left side of the figure relative to its highest point. The heating net 2231 can also be tilted so that its lowest point is located on the right side of the figure relative to its highest point.

[0071] It should be noted that the tilt angle of the heating network 2231 can be specifically 15°, 30°, 45°, etc., and those skilled in the art can reasonably set it according to actual conditions, as long as the mixed liquid can be heated and guided to the starch collection part 225 at the same time.

[0072] In one embodiment of the present invention, a plurality of heating rods 2232 are arranged in pairs on the bottom wall of the starch collection portion 225 and are evenly spaced along the circumference of the bottom wall of the starch collection portion 225. Arranging the heating rods 2232 in pairs helps achieve a more uniform heating effect. Furthermore, arranging the heating rods 2232 evenly spaced along the circumference of the bottom wall of the starch collection portion 225 ensures that the entire bottom wall of the starch collection portion 225 is covered by the heating rods 2232, thereby evenly heating the mixed liquid.

[0073] It should be noted that when the starch mixture is in contact with the heating net 2231 and the heating rod 2232 and is heated, in order to avoid part of the starch from sticking to the heating net 2231 and the heating rod 2232 after drying, thereby affecting the heating efficiency, those skilled in the art can set a vibrator or vibrator and other structures on the heating net 2231 and the heating rod 2232 to assist in the shedding or collection of the dried starch.

[0074] In one specific embodiment of the present invention, Figure 1As shown, the starch collecting portion 225 is in the shape of a bucket with a narrowed lower end, so that the starch can naturally gather to the bottom under the action of gravity during the collection process. As the distillation process proceeds, starch gradually accumulates in the starch collecting portion 225. The bucket-shaped structure guides the starch to concentrate at its lower end, which is conducive to improving the collection efficiency of starch. When it is necessary to discharge starch from the secondary separation chamber 221 to the starch collection bin 4 outside the secondary separation chamber 221, the starch can flow out smoothly through the second discharge channel 226 formed at the lower end of the starch collecting portion 225, and directly enter the starch collection bin 4 specifically used for storing starch, and the starch can be recycled.

[0075] In order to facilitate a full understanding of the use of the steam separation device 2 of the potato peeling device 1 provided in the embodiment of the present invention, the following Figure 1 and Figure 2 The working process of the steam separation device 2 is described.

[0076] During the potato steam peeling stage, the potato peeling is carried out using high-temperature and high-pressure steam in the high-pressure peeling tank 10. The steam after peeling is mixed with potato peels, mud, soluble starch, etc. The high-pressure exhaust gas mixed with impurities is discharged through the steam exhaust channel 11 and introduced into the steam introduction channel 202. After entering the cooling chamber 201, the high-pressure exhaust gas flows toward the heat exchange component 204. When flowing through the air flow pipe 2041 of the heat exchange component 204, it is affected by the low temperature of the coolant pipe 2042. When it encounters cold on the wall of the air flow pipe 2041, it condenses into condensed water, and under the action of gravity, it flows in the vertical direction ( Figure 1The condensed water (in the Y direction) is collected into the condensation water channel 203 at the lower end of the cooling chamber 201. When a certain amount of condensed water is collected in the condensation water channel 203, the condensed water is discharged into the primary separation chamber 211 through the first feed port 212 connected to the condensation water channel 203. The liquid starch mixture flows from the upper side of the filter screen 2141 in the primary separation chamber 211 to the mixture channel 213 below the filter screen 2141. Solid impurities such as potato peels are blocked on the upper side of the filter screen 2141. The scraper 2142 is manually or automatically controlled to slide from the highest point to the lowest point of the filter screen 2141, scraping the potato peels to the lowest point and discharging them from the first discharge channel 215. After the primary filtration, the mixed liquid containing soluble starch flows into the secondary separation chamber 221 through the second feed port 222 of the secondary separation component 22 connected to the mixed liquid channel 213, and flows vertically downward from the upper end of the secondary separation chamber 221 to the heating network 2231. The mixed liquid passes through the pores of the heating network 2231 and is dispersed into smaller water droplets, which increases the heating area of ​​the mixed liquid, thereby preheating the mixed liquid. The mixed liquid that passes through the heating network 2231 and flows to the bottom of the secondary separation chamber 221 contacts the heating rod 2232 and undergoes a second heating. This process can separate the starch from the mixed liquid and collect it in the starch collection part 225. When the collection volume reaches a certain level, the second discharge channel 226 is opened to discharge the distilled and separated starch into the starch collection bin 4 for recycling, thereby improving resource utilization. The water vapor generated during the heating process has been freed of impurities compared to the high-pressure exhaust gas initially introduced into the cooling chamber 201, and can be used for other subsequent processing steps.
