Description

Technical Field

[0001] This application relates to the technical field of potato frying equipment, and specifically relates to a frying device for potatoes. Background Art

[0002] Potatoes are one of the important agricultural products in our country. They are characterized by high yields and rich nutrition, and are important crops that can be used as food, vegetables, feed, and industrial raw materials in our country. Currently, there are various processing methods for potatoes. Among them, the sour and spicy fried potato pieces made from potatoes are one of the commonly eaten snacks.

[0003] However, in related retail enterprises, the current potato block frying equipment generally has the following problems:

[0004] First, after frying is completed, it is necessary to take out the frame-shaped container filled with potato pieces from the frying cavity. During this process, the frame-shaped container will carry a small amount of high-temperature oil. The operator needs to swing the frame-shaped container up and down or left and right to make the oil fall back into the frying cavity. However, during the swinging process, oil splashing is likely to occur, which not only poses a threat to the safety of the operator, but also is not conducive to maintaining the hygiene of the frying area.

[0005] Second, the frame-shaped container is placed in the frying cavity by relying on two support rods. The support rods generally form an L shape. The horizontal section is placed in the frying cavity for carrying the frame-shaped container, and the vertical section is movably sleeved on the equipment. Although such support rods can facilitate the adjustment of the relative positions of the two support rods to adapt to frame-shaped containers of different width dimensions, such support rods are also prone to horizontal section deviation, resulting in uneven loading of the frame-shaped container and tipping over. Utility Model Content

[0006] In order to solve the technical problems in the related art, this application provides a frying device for potatoes.

[0007] In order to achieve the above object, the technical solution adopted in this application is: a frying device for potatoes, including a frying main body and a frying component;

[0008] The top surface of the frying main body is recessed inward to form a frying cavity for carrying out frying operations;

[0009] The frying component includes a frying frame and a guiding member. The frying frame includes a frame body, a holding handle, a sliding rod, and a supporting rod. The frame body is used to accommodate potato pieces and to extend into the frying cavity. The holding handle and the sliding rod are oppositely arranged on two sides of the frame body. One end of the holding handle is connected to the frying frame, and the other end of the holding handle is for manual gripping. One end of the supporting rod is connected to the holding handle, and the other end of the supporting rod is for abutting against the frying main body. One end of the sliding rod is connected to the frying frame, and the other end of the sliding rod forms an annular structure. The guiding member includes a guiding rod and a limiting block. The annular structure is slidably sleeved on the guiding rod. The guiding rod includes a first section, a second section, and a third section connected in sequence. The first section extends in the vertical direction, and one end of the first section away from the second section is installed on the frying main body. The second section is arranged as an arc-shaped bending structure, and the third section is arranged to extend horizontally or obliquely downward. The limiting block is arranged on the first section, and the radial dimension of the limiting block is larger than the radial dimension of the first section.

[0010] The frying device for potatoes includes a frying state and a pouring state. In the frying state, the opening direction of the frame body is vertically upward, the supporting rod abuts against the frying main body, and the annular structure abuts against the limiting block, so that the frame body is located in the frying cavity and does not contact the side wall and the bottom wall of the frying cavity. In the pouring state, the opening direction of the frame body extends in the horizontal direction or in an obliquely downward direction, and the annular structure is sleeved on the third section.

[0011] Optionally, the top surface of the frying main body further recesses inward to form a placement cavity spaced from the frying cavity. Two adjacent sides of the placement cavity respectively extend to the side walls of the frying main body so that the two adjacent sides of the placement cavity communicate with the outside. And in the pouring state, the placement cavity is located below the frying frame.

[0012] Optionally, the frame body includes an annular installation frame and a frying net formed as an inverted frustum frame structure with a smaller bottom and a larger top. The frying net is connected to the annular installation frame. The holding handle and the sliding rod are respectively arranged on two opposite sides of the annular installation frame and are connected to the annular installation frame.

[0013] Optionally, the holding handle includes a connecting portion and a gripping portion. The connecting portion is formed as a U-shaped structure. The connecting portion includes a first connecting rod and a second connecting rod arranged oppositely, and a third connecting rod arranged between the first connecting rod and the second connecting rod. The gripping portion is connected to the middle of the third connecting rod and is for manual gripping.

[0014] Among them, two support rods are provided, and the two support rods are respectively connected to the first connecting rod and the second connecting rod.

[0015] Optionally, the inner diameter dimension of the annular structure is greater than the radial dimension of the guide rod, and the outer diameter dimension of the annular structure is less than or equal to the radial dimension of the limiting block.

[0016] Optionally, one end of the third section far from the second section is connected to the frying main body.

[0017] Beneficial effects:

[0018] 1. Through the above technical solutions, on the one hand, please refer to Figures 2 to 4 , during the process of pouring out the potato pieces in the frame body after frying, the operator controls the frame body to gradually change from the frying state to the pouring state along the guide rod by holding the handle. During this process, the frame body gradually tilts, but its overall is still above the frying cavity. Therefore, the oil that gradually slides off the frame body due to gravity will completely and smoothly drip back into the frying cavity along the tilted frame body. The operator only needs to control the speed of lifting the frame body. In this way, the operator does not need to swing the frying frame, so it can effectively avoid oil splashing, and further effectively avoid the problems of splashing oil hurting people and damaging the sanitary conditions.

[0019] Among them, it can be understood that although the frame-shaped container of the existing frying equipment can also return the oil by slowly tilting, the operator may choose a faster operation method, that is, swinging up and down or left and right, due to factors such as convenient meal serving and labor saving. However, the guiding member provided in this application can not only realize the guiding of the control frame, but also form a limit on the control frame, so that the operator cannot swing, and can compulsorily standardize the operation method of the operator.

[0020] On the other hand, during the frying process, the frame body of this application is suspended in the frying cavity through the cooperation of the support rod, the sliding rod and the limiting block. Specifically, one side of the frame body is supported by the part of the handle and the support rod, and the other side of the frame body is supported by the sliding rod, the limiting block and a part of the first section, so that the frame body can be suspended in the frying cavity. Among them, the sliding rod connected to the frame body is sleeved on the guide rod. Therefore, in the frying state, the relative position of the frame body will not change, and it can effectively avoid the frame body from tipping over during the frying process, and further effectively avoid the problems of personal injury, equipment damage or resource waste that may be caused by the tipping of the frame body.

[0021] 2. Other beneficial effects or advantages of this application will be described in detail in combination with the specific structure in the specific implementation manner. Brief Description of the Drawings

Detailed Description of the Embodiments

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Components of the embodiments of this application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application that is claimed, but merely represents selected embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0033] In the description of this application, it should be noted that the terms used, such as "top surface" and "bottom surface", refer to the upper surface of the potato frying device of this application facing upward and the lower surface facing downward in the use state; the terms used, such as "first" and "second", are only for distinguishing expressions, rather than indicating or implying any difference in importance or order; the terms used, such as "inside" and "outside", refer to the inside and outside of the specific contour. The use of the above terms is only for the convenience of clearly and simply expressing the technical solutions of this application and should not be construed as a limitation of this application.

[0034] To facilitate a clearer and more accurate understanding of the technical solutions of this application by relevant technical personnel, the following will first take Figure 1 as an example to illustrate the existing relevant potato frying equipment.

[0035] Currently, the processing process of fried potato pieces on the market is generally as follows: putting the pre-prepared potato pieces (which can be semi-cooked potato pieces that have been fried beforehand or raw potato pieces) into a frame-shaped container as shown in Figure 1 , and then putting the frame-shaped container filled with potato pieces into the frying chamber and suspending it in the frying chamber by relying on a support rod to facilitate the frying treatment of the potato pieces in the frame-shaped container.

[0036] After frying is completed, it is necessary to transfer the potato pieces out for further processing. At this time, the current potato frying equipment requires the operator to hold the frame-shaped container and take it out. During this process, a small amount of high-temperature oil adheres to the frame-shaped container. Currently, the operator generally shakes the frame-shaped container up and down or left and right to make the oil adhering to it drip back into the frying chamber. However, during the shaking process, oil splashing is likely to occur, which may not only cause harm to the operator, but also the oil splashed on the ground or other equipment will greatly affect the hygiene condition of the frying area.

[0037] Meanwhile, during the frying process, the stable placement of the frame-shaped container is achieved by relying on two L-shaped support rods. Since only one end of each support rod is slidably connected to the adjusting rod of the frying device, although the relative position or spacing between the two support rods can be adjusted to accommodate frame-shaped containers of different width dimensions, precisely because of their slidable connection to the frying device, it is also prone to causing the support rods to shift horizontally, thus making it impossible for the two support rods to stably hold the frame-shaped container. In this way, the frame-shaped container may tip over due to uneven loading, resulting in personal injury to the operator, damage to the equipment, or waste of potatoes and oil.

[0038] In view of this, the present application provides a brand-new solution, that is, the frying device 100 for potatoes in the present application. By re-improving the structure of the frying frame 21 and newly setting a guiding member 22, the movement path of the frying frame 21 is restricted to a certain extent, so that the oil can stably and reliably fall back into the frying chamber 11 during the movement of the frying frame 21 by relying on the self-weight of the oil, effectively avoiding oil splashing. Furthermore, it can effectively avoid the problems of splashed oil injuring people and damaging the sanitary conditions. At the same time, the frying frame 21 provided in the present application is stably placed through the support rod 214 and the guiding member 22, which can effectively support the frying frame 21, and thus can effectively avoid the problems of personal injury, equipment damage, or resource waste that may be caused by the tipping of the frying frame 21.

[0039] The technical solution of the present application will be described in detail below with reference to the accompanying drawings.

[0040] Embodiment 1

[0041] As Figures 2 to 6As shown in the figure, this embodiment provides a frying device 100 for potatoes, which includes a frying main body 1 and a frying component 2. The top surface of the frying main body 1 is recessed inward to form a frying cavity 11 for carrying out frying operations. The frying component 2 includes a frying frame 21 and a guiding member 22. The frying frame 21 includes a frame body 211, a holding handle 212, a sliding rod 213 and a support rod 214. The frame body 211 is used to accommodate potato pieces and extend into the frying cavity 11. The holding handle 212 and the sliding rod 213 are oppositely arranged on both sides of the frame body 211. One end of the holding handle 212 is connected to the frying frame 21, and the other end of the holding handle 212 is for manual holding. One end of the support rod 214 is connected to the holding handle 212, and the other end of the support rod 214 is for abutting against the frying main body 1. One end of the sliding rod 213 is connected to the frying frame 21, and the other end of the sliding rod 213 is formed into a ring structure; the guiding member 22 includes a guiding rod 221 and a limiting block 222. The ring structure is slidably sleeved on the guiding rod 221, and the guiding rod 221 includes a first section 2211, a second section 2212 and a third section 2213 connected in sequence. The first end extends in the vertical direction, and one end of the first section 2211 away from the second section 2212 is installed on the frying main body 1. The second section 2212 is arranged as an arc-shaped bending structure, and the third section 2213 is arranged to extend in the horizontal direction or incline downward. The limiting block 222 is arranged on the first section 2211, and the radial dimension of the limiting block 222 is larger than the radial dimension of the first section 2211;

[0042] The frying device 100 for potatoes includes a frying state and a pouring state. In the frying state, the opening direction of the frame body 211 is vertically upward, the support rod 214 abuts against the frying main body 1, and the ring structure abuts against the limiting block 222, so that the frame body 211 is located in the frying cavity 11 and does not contact the side wall and the bottom wall of the frying cavity 11; in the pouring state, the opening direction of the frame body 211 extends in the horizontal direction or in the direction inclined downward, and the ring structure is sleeved on the third section 2213.

[0043] Through the above technical solution, on the one hand, please refer to Figures 2 to 4 Figure, after frying is completed, during the process of pouring out the potato pieces in the frame body 211, the operator controls the frame body 211 to gradually change from the frying state to the pouring state along the guiding rod 221 through the holding handle 212. During this process, the frame body 211 gradually inclines, but its whole is still located above the frying cavity 11. Therefore, the oil liquid that gradually slides off the frame body 211 due to gravity will completely and smoothly drip back into the frying cavity 11 along the inclined frame body 211. The operator only needs to control the speed of lifting the frame body 211. In this way, the operator does not need to swing the frying frame 21. Therefore, it is possible to effectively avoid oil splashing, and further effectively avoid the problems of splashing oil hurting people and damaging the sanitary condition.

[0044] Among them, it can be understood that although the frame-shaped container of the existing frying equipment can also return the oil by slowly tilting, however, due to factors such as convenient and labor-saving food serving, the operator may choose a faster operation method, that is, shaking up and down or left and right. The guiding member 22 provided in this application can not only guide the frame body 211, but also limit the frame body 211, so that the operator cannot shake it, and can compulsorily standardize the operation method of the operator.

[0045] On the other hand, during the frying process, the frame body 211 of this application is suspended in the frying chamber 11 by the support rod 214, the sliding rod 213 and the limiting block 222 together. Specifically, one side of the frame body 211 is supported by a part of the holding handle 212 and the support rod 214, and the other side of the frame body 211 is supported by the sliding rod 213, the limiting block 222 and a part of the first section 2211, so that the frame body 211 can be suspended in the frying chamber 11. Among them, the sliding rod 213 connected to the frame body 211 is sleeved on the guiding rod 221. Therefore, in the frying state, the relative position of the frame body 211 will not change, and it is possible to effectively prevent the frame body 211 from tipping over during the frying process, and further effectively avoid the problems of personal injury, equipment damage or resource waste that may be caused by the tipping of the frame body 211.

[0046] In an embodiment of this application, as Figures 2 to 4 shown, the top surface of the frying main body 1 of this application can also be recessed inward to form a placement cavity 12 spaced from the frying chamber 11. Adjacent sides of the placement cavity 12 extend to the side walls of the frying main body 1 respectively to communicate the adjacent sides of the placement cavity 12 with the outside. And, in the dumping state, the placement cavity 12 is located below the frying frame 21.

[0047] In this way, the placement cavity 12 can be used to place a container for holding the fried potato pieces. In the dumping state, the potato pieces in the frame body 211 will fall into the container placed in the placement cavity 12 for further processing. At the same time, this embodiment arranges the placement cavity 12 beside the frying chamber 11, which can well reduce the moving path of the frame body 211 and is convenient for improving production efficiency. In addition, the two sides of the arranged placement cavity 12 are open, which is convenient for the operator to take and place the container in the placement cavity 12.

[0048] In an embodiment of this application, as Figure 6As shown, the frame body 211 of the present application may include an annular mounting frame 2111 and a frying net 2112 formed in an inverted frustum frame structure with a smaller bottom and a larger top. The frying net 2112 is connected to the annular mounting frame 2111. The holding handle 212 and the sliding rod 213 are respectively arranged on opposite sides of the annular mounting frame 2111 and connected to the annular mounting frame 2111.

[0049] In this way, the annular mounting frame 2111 can serve as a reliable mounting structure for the frying net 2112 to facilitate maintaining the structural stability of the frying net 2112. At the same time, the frying net 2112 is formed in an inverted frustum frame structure with a smaller bottom and a larger top. In this way, when in a tilted state, the potato pieces in the frying net 2112 can fall out more conveniently.

[0050] In an embodiment of the present application, as Figure 6 shown, the holding handle 212 of the present application includes a connecting portion 2121 and a holding portion 2122. The connecting portion 2121 is formed in a U-shaped structure. The connecting portion 2121 includes a first connecting rod 2121a and a second connecting rod 2121b arranged oppositely, and a third connecting rod 2121c arranged between the first connecting rod 2121a and the second connecting rod 2121b. The holding portion 2122 is connected to the middle of the third connecting rod 2121c and is used for manual holding. Among them, two support rods 214 are provided, and the two support rods 214 are respectively connected to the first connecting rod 2121a and the second connecting rod 2121b.

[0051] In this way, through the two support rods 214 arranged in this way, they can cooperate with the sliding rod 213 on the other side to jointly form a three-point support for the frame body 211, which can further improve the stability of the frame body 211 during frying and more reliably prevent the frame body 211 from tipping over.

[0052] In an embodiment of the present application, the inner diameter dimension of the annular structure of the present application is larger than the radial dimension of the guide rod 221, and the outer diameter dimension of the annular structure is smaller than or equal to the radial dimension of the limit block 222.

[0053] In this way, on the one hand, the annular structure can move more flexibly on the guide rod 221. In addition to moving along the direction of the guide rod 221, the annular structure can also have a certain degree of moving space along the radial direction of the guide rod 221, thereby facilitating the operator to more conveniently control the annular structure to pass through the bent second section 2212. On the other hand, with the annular structure and the limit block 222 arranged in this way, the limit block 222 can support the limit structure more stably and reliably, which is beneficial to increasing the contact area between the annular structure and the limit block 222, and further beneficial to improving the stability of the frame body 211 in the frying state.

[0054] Currently, during the use of existing potato frying equipment, operators may, for the sake of convenience, casually place the frame-shaped container on the workbench (which often has other equipment or sundries, such as oil stains, scattered seasonings, etc.) when frying is not required. In this way, the hygiene condition of the frame-shaped container cannot be guaranteed.

[0055] In view of this, in one embodiment of the present application, as Figure 2 shown, one end of the third section 2213 of the present application, which is far from the second section 2212, is connected to the frying main body 1. In this way, the maximum displacement range of the frame body 211 can be limited, and the frame body 211 can be prevented from detaching from the guide rod 221, so as to prevent the operator from casually placing the frame body 211 and affecting its hygiene condition. At the same time, the stability of the guide rod 221 can also be effectively improved.

[0056] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
