Description

Technical Field

[0001] This utility model belongs to the field of deep-frying machinery technology, specifically relating to a double-headed boat-shaped deep fryer. Background Technology

[0002] Large continuous fryers are commonly used in food processing plants for frying food. The frying process mostly involves using a high-temperature resistant conveyor belt to propel food through the high-temperature oil in the frying chamber. When frying foods with high water content, such as vegetables (e.g., fried eggplant fritters), fruits (e.g., fruit spring rolls), and some frozen ingredients, the moisture mixed with the high-temperature oil can cause severe oil splattering. This not only wastes oil and rapidly degrades its quality but also poses safety hazards. Therefore, there is a current need to develop and improve the structure of fryers specifically for frying foods with high water content. Utility Model Content

[0003] This utility model provides a double-headed boat-shaped fryer, which aims to improve the oil-saving and safety aspects of frying foods with high water content.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a double-headed boat-shaped fryer, comprising: The frame is equipped with an outer casing and a retractable fume hood; The inner liner is located inside the outer shell. The bottom wall of the inner liner slopes down from both ends to the middle along its length to form two first slopes. The middle part of the bottom wall of the inner liner is recessed to form a low-temperature cavity area that connects with the two first slopes. Heating tubes are arranged above the low-temperature cavity area to form a high-temperature frying zone. Two mesh belts are connected to the frame at intervals, forming a conveying channel between them. The two ends of the conveying channel extend slopingly along the slope and pass horizontally through the high-temperature frying zone in the middle. The low-temperature cavity is equipped with at least one layer of heat-insulating tubes, with both ends of the heat-insulating tubes open and extending out of the inner liner to form air convection.

[0005] In one possible implementation, the bottom of the low-temperature cavity gradually slopes downward from both ends toward the middle to form two interlocking guide slopes. A slag removal pipe is provided at the junction of the two guide slopes, and the slag removal pipe extends out of the side wall of the low-temperature cavity and is connected to the first valve.

[0006] In some embodiments, a viewing window is provided on the side wall of the cryogenic chamber, and an oil level mark is provided at the center of the viewing window. The oil level mark is used to indicate the height of the oil-water interface in the cryogenic chamber to determine the opening time of the first valve.

[0007] For example, the side wall of the low-temperature cavity is provided with an oil outlet pipe, which is higher than the slag removal pipe and is equipped with a second valve.

[0008] For example, the bottom wall of the inner liner slopes downwards from both sides towards the middle in its width direction to form two second slopes. The low-temperature cavity is located between the two second slopes and the cavity opening is connected to the two second slopes.

[0009] In one possible implementation, the frame includes a fixed frame and a lifting frame. The fixed frame is fixedly supported on the ground and connected to the outer shell. The lifting frame is hooked to the fume hood via hooks. The lifting frame has a lower position that overlaps the outer shell and an upper position that is raised above the outer shell along with the fume hood. The lifting frame is provided with a first longitudinal beam and a second longitudinal beam at intervals on the upper and lower sides, respectively for corresponding installation of one of the mesh belts.

[0010] In some embodiments, the mounting frame has at least two gantry beams spaced apart along its length, each gantry beam being slidably connected to the fume hood in the vertical direction, and the top of the gantry beam is provided with a lifting mechanism, the output end of which is connected to the fume hood.

[0011] For example, the first longitudinal beam includes two first beams that are fixed to the bottom of the lifting frame; the second longitudinal beam includes two second beams that are suspended from the lifting frame by a number of lifting adjustment components, and the two second beams are located directly above the two first beams.

[0012] For example, the lifting adjustment component includes a screw rod that is fixedly inserted vertically into the second beam and a screw sleeve that is rotatably connected to the lifting frame; wherein, the screw rod extends through the screw sleeve to the top of the lifting frame and is connected to a handwheel, and the screw rod and the screw sleeve form a threaded engagement.

[0013] In some embodiments, a sprocket is fixedly connected to one end of the screw sleeve, which is used to connect the various lifting adjustment components of the two second beams to be aligned in pairs in the width direction of the frame, and the sprockets of the two aligned lifting adjustment components are connected by a chain.

[0014] The beneficial effects of the double-headed boat-shaped fryer provided by this utility model are as follows: Compared with the prior art, the double-headed boat-shaped fryer of this utility model has an outer shell on the frame forming the outer casing of the inner liner, thereby avoiding the risk of burns caused by the exposed inner liner. Furthermore, the use of a liftable fume hood to cover the outer shell during frying not only prevents oil from splashing outwards but also collects oil fumes, thus improving the safety and environmental friendliness of the frying process. The raised fume hood facilitates cleaning of the inner liner, making operation convenient. The inner liner forms a double-headed boat-shaped structure based on the first inclined surface at both ends. On the one hand, this reduces the oil capacity at both ends of the inner liner, concentrating the frying oil in the high-temperature frying zone in the middle of the inner liner to fry the food, which is beneficial for improving oil-saving frying. On the other hand, it allows the moisture from high-moisture foods to enter the low-temperature cavity area recessed in the middle of the inner liner along the first inclined surface, thereby reducing the moisture entering the high-temperature frying zone, which helps to alleviate oil splattering and reduce oil waste. Because the heating element is positioned above the low-temperature frying zone, and high-temperature frying oil typically flows upwards, the oil in the low-temperature cavity can be kept at a low temperature. Furthermore, the heat-insulating tube passing through the low-temperature cavity not only prevents frying oil from entering the low-temperature cavity to a certain extent, but also allows the air passing through the heat-insulating tube to carry away the heat from the low-temperature cavity. This keeps the oil temperature in the low-temperature frying zone below the boiling point of water, thus preventing the evaporation of water entering the low-temperature cavity from causing oil splattering. This effectively solves the problem of oil splattering and waste when frying foods with high water content, improving the oil-saving and safety aspects of frying foods with high water content.

In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0019] Please refer to the following: Figures 1 to 7The present invention provides a description of a double-headed boat-shaped fryer. The double-headed boat-shaped fryer includes a frame 10, an inner liner 20, and two mesh belts 40. The frame 10 is equipped with an outer shell 11 and a liftable fume hood 12. The inner liner 20 is located inside the outer shell 11. The bottom wall of the inner liner 20 slopes downwards from both ends towards the middle along its length, forming two first slopes 21. The middle of the bottom wall of the inner liner 20 is recessed to form a low-temperature cavity 22 that connects with the two first slopes 21. A heating pipe 30 is arranged above the low-temperature cavity 22, forming a high-temperature frying zone 23. The two mesh belts 40 are connected vertically to the frame 10 at intervals, forming a conveying channel 400 between them. The two ends of the conveying channel 400 extend obliquely along the slopes, and the middle horizontally passes through the high-temperature frying zone 23. At least one layer of heat-insulating pipes 50 is arranged inside the low-temperature cavity 22. The two ends of the heat-insulating pipes 50 are open and extend out of the inner liner 20 to form air convection.

[0020] It should be noted that the double-headed boat-shaped fryer provided in this embodiment is a continuous fryer with a large length-to-width ratio. In this embodiment, the mesh belt 40 can be specifically understood as a mesh belt 40 conveyor with a food-grade high-temperature resistant stainless steel belt as the conveyor belt surface. The length and width of the belt surface match the size of the inner liner 20. Considering that the mesh belt 40 conveyor is a mature existing technology and is widely used in this field, it will not be described in detail here.

[0021] The two mesh belts 40, spaced vertically, run in opposite directions, meaning that the lower surface of the upper mesh belt 40 and the upper surface of the lower mesh belt 40 run in the same direction. This allows the food passing through the conveyor channel 400 between the two mesh belts 40 to move forward continuously under the continuous oscillation of the two mesh belts 40.

[0022] The closer the frying oil in the inner liner 20 is to the heating tube 30, the higher its temperature. It also tends to move upwards from the area near the heating tube 30. Therefore, the frying oil temperature in the low-temperature cavity 22 located below the heating tube 30 is much lower than the oil temperature in the high-temperature frying zone 23. In addition, the heat-insulating tube 50 installed in the low-temperature cavity 22 can prevent the high-temperature frying oil in the high-temperature frying zone 23 from moving into the low-temperature cavity 22. At the same time, the air flowing inside the heat-insulating tube 50 can carry away the heat from the low-temperature cavity 22. Combining these factors, the oil temperature in the low-temperature cavity 22 can be controlled below 100 degrees Celsius, thereby preventing the evaporation of water entering the low-temperature cavity 22 from generating rising bubbles that could cause an oil explosion.

[0023] Because water is denser than frying oil, food with high water content quickly sinks to the first slope 21 after entering the inner pot 20, and then slides down the slope 21 into the low-temperature cavity 22. This prevents water from mixing into the high-temperature frying zone 23 and causing an oil explosion. It should also be noted that because the heating element 30 is positioned above the low-temperature cavity 22, the frying oil temperature at both ends of the inner pot 20, especially at the feeding end, is also lower than that of the high-temperature frying zone 23. This allows sufficient time for water to sink and slide down into the low-temperature cavity 22 before evaporation, thus preventing an oil explosion that occurs the moment food enters the inner pot 20.

[0024] Compared with the prior art, the double-headed boat-shaped fryer provided in this embodiment has an outer shell 11 on the frame 10 to form the outer casing of the inner liner 20, thereby avoiding the risk of burns caused by the inner liner 20 being exposed. On this basis, the liftable fume hood 12 can cover the outer shell 11 during the frying process, which not only prevents the frying oil from splashing outwards, but also collects the oil fumes, thereby improving the safety and environmental protection of the frying process. After the fume hood 12 is raised, the inner liner 20 can be cleaned easily, making the operation convenient.

[0025] The inner liner 20 forms a double-headed boat-shaped structure based on the first inclined slope 21 at both ends. On the one hand, it can reduce the oil capacity at both ends of the inner liner 20, so that the frying oil is concentrated in the high-temperature frying zone 23 in the middle of the inner liner 20 to fry the food, which is conducive to improving the oil-saving performance of frying. On the other hand, it can allow the moisture of high-moisture food to enter the low-temperature cavity zone 22 in the middle of the inner liner 20 along the first inclined slope 21, thereby reducing the moisture entering the high-temperature frying zone 23, which is conducive to alleviating the oil explosion phenomenon and reducing the waste of frying oil splashing.

[0026] Since the heating tube 30 is located above the low-temperature frying zone, and the high-temperature frying oil usually flows upward, the frying oil in the low-temperature cavity zone 22 can be kept at a low temperature. On this basis, the heat-insulating tube 50 passing through the low-temperature cavity zone 22 can not only block the frying oil in the high-temperature frying zone 23 from entering the low-temperature cavity zone 22 to a certain extent, but also use the air passing through the heat-insulating tube 50 to carry away the heat of the low-temperature cavity zone 22, thereby controlling the oil temperature in the low-temperature frying zone below the boiling point of water. This avoids the evaporation of water entering the low-temperature cavity zone 22, which can cause oil explosion. It can effectively solve the problem of oil splattering and waste when frying foods with high water content, and improve the oil-saving and safety of frying foods with high water content.

[0027] In some embodiments, see Figure 3 and Figure 4The bottom of the cryogenic cavity 22 slopes downwards from both ends towards the middle, forming two interlocking guide slopes 221. A slag removal pipe 222 is installed at the junction of the two guide slopes 221. The slag removal pipe 222 extends out of the side wall of the cryogenic cavity 22 and connects to the first valve 223. The guide slopes 221 allow sinking water droplets to accumulate near the slag removal pipe 222. When the water accumulation in the cryogenic cavity 22 reaches a certain height, the first valve 223 can be opened to drain the water from the slag removal pipe 222, thereby preventing excessive water accumulation in the cryogenic cavity 22 and the risk of oil explosion.

[0028] It should be noted that, as Figure 2 As shown, in this embodiment, a viewing window 224 is provided on the side wall of the low-temperature cavity 22, and an oil level scale line is provided at the center of the viewing window 224. The oil level scale line is used to indicate the height of the oil-water interface in the low-temperature cavity 22 to determine when to open the first valve 223. By providing the viewing window 224, the water level in the low-temperature cavity 22 can be easily observed at any time, and the height of the oil-water interface in the low-temperature cavity 22 can be accurately read using the oil level scale line, thereby judging the amount of water in the low-temperature cavity 22. This allows the operator to open the first valve 223 in time to drain the water, thus avoiding excessive water accumulation in the low-temperature cavity 22 and affecting normal frying operations.

[0029] As a modified embodiment of the aforementioned inner liner 20, please refer to Figure 4 The side wall of the low-temperature chamber 22 is provided with an oil outlet pipe 225, which is higher than the slag removal pipe 222 and is equipped with a second valve 226. When it is necessary to change the frying oil, the second valve 226 can be opened directly to discharge the frying oil through the oil outlet pipe 225. Since the oil outlet pipe 225 is higher than the slag removal pipe 222, it can prevent the water accumulated at the bottom of the low-temperature chamber 22 from being discharged with the oil during the oil discharge process, thereby reducing the workload of subsequent oil-water separation treatment.

[0030] For some possible implementations, please refer to [link / reference]. Figure 4 The bottom wall of the inner liner 20 slopes downwards from both sides towards the middle in its width direction, forming two second slopes 24. The low-temperature cavity zone 22 is located between the two second slopes 24, and its opening is connected to the two second slopes 24. The second slopes 24 can further reduce the bottom area of ​​the high-temperature frying zone 23, thereby reducing the amount of frying oil used while ensuring that the frying oil level meets the requirements, thus improving the oil-saving performance of frying. In addition, both the first slope 21 and the second slope 24 can guide the frying oil to flow into the low-temperature cavity zone 22, thereby improving the thoroughness of oil drainage when changing the frying oil and avoiding the residue of waste frying oil that affects the quality of the newly added frying oil.

[0031] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6The aforementioned frame 10 includes a fixed frame 13 and a lifting frame 14. The fixed frame 13 is fixedly supported on the ground and connected to the outer shell 11. The lifting frame 14 is hooked to the fume hood 12 via a hook 141. The lifting frame 14 has a lower position that overlaps the outer shell 11 and an upper position that is raised above the outer shell 11 along with the fume hood 12. The lifting frame 14 is provided with a first longitudinal beam 142 and a second longitudinal beam 143 at intervals on the upper and lower sides, respectively for corresponding installation of one of the mesh belts 40.

[0032] Here, the hook 141 can be hinged to the hood 12. By swinging the hook 141, it can be hooked and unhooked from the lifting frame 14. When the hook 141 is detached from the lifting frame 14, the hood 12 can be raised and lowered independently. When the hook 141 is hooked to the lifting frame 14, the two mesh belts 40 installed on the lifting frame 14 can be raised together with the hood 12, thereby facilitating the cleaning of the inner liner 20.

[0033] For details, see Figure 1 and Figure 2 The fixed frame 13 has at least two gantry beams 131 spaced apart along its length. Each gantry beam 131 is slidably connected to the smoke hood 12 in the vertical direction. The top of the gantry beam 131 is provided with a lifting mechanism 60, and the output end of the lifting mechanism 60 is connected to the smoke hood 12.

[0034] The gantry's uprights can be used to establish a sliding fit with the side wall of the smoke hood 12, thereby improving the connection and movement stability of the smoke hood 12. At the same time, the top beam of the gantry can be used to install the lifting mechanism 60. Here, the lifting mechanism 60 can be a winch or a rotary drive such as the sprocket 1444 at the output end of a motor, which drives the traction chain connected to the smoke hood 12 to lift and lower the smoke hood 12. There are many similar existing lifting structures, which will not be described in detail here.

[0035] For some possible implementations, please refer to [link / reference]. Figure 6 The first longitudinal beam 142 includes two first beams that are fixed to the bottom of the lifting frame 14; the second longitudinal beam 143 includes two second beams that are suspended from the lifting frame 14 by a number of lifting adjustment components 144, and the two second beams are located directly above the two first beams.

[0036] Both the first beam and the second beam can be two oppositely arranged channel beams or folded edge beams, which can facilitate the installation of the mesh belt 40 while ensuring structural rigidity. The second longitudinal beam 143 is connected to the lifting frame 14 through the lifting adjustment component 144 and can adjust its height, thereby adjusting the height of the conveying channel 400 formed by the two mesh belts 40. This can meet the frying needs of different sized foods and improve the applicability of the equipment.

[0037] For example, please refer to Figure 6 and Figure 7 The aforementioned lifting adjustment component 144 includes a screw 1441 vertically fixedly inserted into the second beam and a screw sleeve 1442 rotatably connected to the lifting frame 14. The screw 1441 extends through the screw sleeve 1442 to the top of the lifting frame 14 and is connected to a handwheel 1443. The screw 1441 and the screw sleeve 1442 form a threaded engagement. By operating the handwheel 1443, the screw sleeve 1442 can be rotated, thereby using the threaded engagement to drive the screw 1441 to rise or fall, thus achieving height adjustment of the second beam. This allows for changes in the distance between the mesh belt 40 connected to the second beam and the mesh belt 40 below, realizing height adjustment of the conveying channel 400. The operation is simple and convenient.

[0038] like Figure 7 As shown, in this embodiment, one end of the aforementioned threaded sleeve 1442 is fixedly connected to a sprocket 1444, which is used to connect the lifting adjustment components 144 of the two second beams to be aligned in pairs in the width direction of the frame 10. The sprockets 1444 of the two aligned lifting adjustment components 144 are connected by a chain 1445. The transmission connection between the sprocket 1444 and the chain enables the two threaded sleeves 1442 to rotate synchronously, thereby enabling the two second beams to rise and fall synchronously. This not only improves the adjustment convenience of the conveyor channel 400, but also avoids height deviation on both sides of the mesh belt 40 during the adjustment process, thus ensuring the consistency of the height dimensions on both sides of the conveyor channel 400.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
