Description

Technical Field

[0001] The invention relates to a peanut oil preparation technology, in particular to an automatic frying device used for peanut oil processing. Background Art

[0002] Peanut oil is made from peanuts. After multiple pre-processing steps such as cleaning, shelling, frying and crushing, it is pressed and filtered to obtain the finished peanut oil.

[0003] Frying is an extremely important part of the pretreatment process for the preparation of peanut oil. Uneven heating during the frying process will directly lead to some peanuts not being cooked through and some being burnt, making the final peanut oil of poor quality, darker in color and having a burnt smell. In addition, when the peanuts are not cooked through, the oil yield will be seriously affected, and the peanut kernels are soft in texture, which is not convenient for subsequent pressing.

[0004] Peanut frying methods include manual frying and machine frying. During manual frying, although the frying flexibility is good, it is difficult to ensure the uniformity of frying for each batch, and the labor intensity is relatively high. When the existing frying equipment is frying, the peanut kernels are simply flipped mainly by a stirring rod, which is prone to dead corners of frying, resulting in uneven heating of the peanut kernels. As a result, not only some peanuts cannot fully release aromatic substances, affecting the flavor of the peanut oil, but also the oil yield of the peanuts is reduced and the cost of peanut oil production is increased. Therefore, the present application provides an automatic frying device for peanut oil processing to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example: See also Figure 1-Figure 8 An automatic frying device for peanut oil processing includes a frying pot 1, which includes an inner pot 101 arranged inside and an insulating outer shell 102 arranged outside. Electromagnetic coils 103 are arranged on the outside and bottom of the inner pot 101. A feeding port 104 cooperating with a sealing cover is arranged on the top of the frying pot 1, and a discharging port 105 equipped with a closed door is arranged on the side of the frying pot 1.

[0021] It should be noted that the stir-fry pot 1 is also provided with a temperature sensor which can monitor the internal temperature of the inner pot 101 in real time, and the temperature sensor and the electromagnetic coil 103 are connected to an external control system, so that the stir-frying temperature can be controlled in real time and accurately during the stir-frying process.

[0022] A rotating shaft 2 is arranged inside the stir-fry pot 1, and the rotating shaft 2 is driven by a motor. A plurality of mounting blocks 21 are arranged at intervals on the outside of the rotating shaft 2. Stirring plates 22 are arranged on both sides of the mounting blocks 21, and the stirring plates 22 are arranged in an arc shape. An adjusting unit is arranged outside the mounting block 21, and the adjusting unit is used to intermittently adjust the stirring plates 22 from a vertical state to an inclined state.

[0023] In this embodiment, the adjusting unit includes an active groove 3 opened inside the mounting block 21 and adapted to the stirring plate 22, the inner side surface of the active groove 3 is rotatably connected with a transmission gear 31, the transmission gear 31 is coaxially fixedly connected with the stirring plate 22, the inner side surface of the active groove 3 on the same side is slidably connected with the same connecting strip 32, the bottom end of the connecting strip 32 passes through the upper active groove 3 and is slidably connected with the inner side surface of the active groove 3 at the bottom, the connecting strip 32 is provided with teeth 33 adapted to the transmission gear 31, the teeth 33 are meshed with the transmission gear 31, the outside of the rotating shaft 2 is fixedly connected with a driving gear 34, the top of the frying pot 1 is rotatably connected with driven gears 35 symmetrically distributed on both sides of the driving gear 34, and the driven gear 35 is meshed with the driving gear 34.

[0024] Furthermore, a ring groove corresponding to the driven gear 35 is provided on the top of the frying pot 1, and a ring sleeve 36 is rotatably connected to the inner side of the ring groove, and the ring sleeve 36 is fixedly connected to the driven gear 35. A driving groove 37 is provided inside the ring sleeve 36, and a connecting groove 38 connected to the driving groove 37 is provided at the bottom of the ring sleeve 36. A connecting rod 39 is connected to the top of the connecting strip 32, and a guide ball 310 is fixedly connected to the top of the connecting rod 39.

[0025] It should be noted that the connecting rod 39 is slidably connected to the inner side surface of the connecting groove 38 , and the guide ball 310 is slidably connected to the inner side surface of the driving groove 37 , so that the guide ball 310 can slide smoothly along the inner side surface of the driving groove 37 .

[0026] In this embodiment, the driving groove 37 includes a high-position groove 371, a low-position groove 372 and a buffer groove 373 arranged between the high-position groove 371 and the low-position groove 372. The guide ball 310 is slidably connected to the inner side surfaces of the high-position groove 371, the low-position groove 372 and the buffer groove 373. The arc length ratio of the high-position groove 371 to the driving groove 37 is 2:5, the arc length ratio of the low-position groove 372 to the driving groove 37 is 2:5, and the arc length ratio of the two buffer grooves 373 to the driving groove 37 is 1:5.

[0027] Moreover, the transmission ratio between the driving gear 34 and the driven gear 35 is 5:1, so that when the driving gear 34 rotates 5 times, it can drive the driven gear 35 to rotate 1 time. Therefore, during the peanut frying process, after the driving gear 34 rotates 2 times, the stirring plate 22 switches its state once, that is, the stirring plate 22 rotates 2 times to switch the stirring state once.

[0028] It should be noted that when the guide ball 310 passes through the buffer groove 373 from the high-level groove 371 and enters the low-level groove 372, the connecting bar 32 moves downward and drives the stirring plate 22 to change from an inclined state to a vertical state. When the guide ball 310 passes through the buffer groove 373 from the low-level groove 372 and enters the high-level groove 371, the connecting bar 32 moves upward and drives the stirring plate 22 to change from a vertical state to an inclined state.

[0029] In this embodiment, the tops of all the connecting strips 32 are connected to the same connecting disk 311, the connecting rod 39 is fixedly connected to the connecting disk 311, a convex annular groove 312 is provided at the bottom of the connecting disk 311, and a sliding block 313 is slidably connected to the inner side surface of the convex annular groove 312, and the sliding block 313 is fixedly connected to the connecting strips 32.

[0030] During the working process, the peanut kernels for oil production are put into the frying pot 1 through the feed port 104, and then the motor drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the stirring plate 22 to rotate. During this process, the electromagnetic coil 103 heats the side and bottom of the inner pot 101, so that the peanut kernels are heated under the stirring of the stirring plate 22; During the rotation of the rotating shaft 2, the driving gear 34 is driven to rotate, and the driving gear 34 is driven to rotate the driven gear 35, and the driven gear 35 is driven to rotate the ring sleeve 36. When the ring sleeve 36 rotates, the guide ball 310 is caused to circulate between the high-level groove 371, the buffer groove 373 and the low-level groove 372. When the guide ball 310 passes through the buffer groove 373 from the high-level groove 371 and enters the low-level groove 372, the guide ball 310 moves downward and drives the connecting bar 32 to move downward. With the cooperation of the teeth 33 provided on the connecting bar 32, the connecting bar 32 drives the transmission gear 31 to rotate when it moves downward, so that the transmission gear 31 rotates and drives the stirring plate 22 to rotate, so that the stirring plate 22 changes from an inclined state to a vertical state, so that when the rotating shaft 2 drives the stirring plate 22 to rotate, it can push the peanut kernels near the middle of the inner pot 101 to the outside; When the guide ball 310 passes through the buffer groove 373 from the low-level groove 372 and enters the high-level groove 371, the guide ball 310 moves upward and drives the connecting bar 32 to move upward. The connecting bar 32 moves upward to drive the transmission gear 31 to rotate in the opposite direction, so that the stirring plate 22 changes from a vertical state to an inclined state. Therefore, during the peanut oil frying process, the stirring plate 22 can intermittently adjust the stirring state. Therefore, during the process of the rotating shaft 2 driving the stirring plate 22 to rotate, the stirring plate 22 can push the peanut kernels at the bottom of the inner pot 101 upward; During the frying process of peanut kernels for oil production, the peanut kernels inside the frying pot 1 are intermittently stirred horizontally and vertically to ensure the uniformity of frying, thereby achieving a better pre-treatment frying effect of the peanut kernels, which can not only effectively improve the oil yield of peanut oil preparation, but also improve the quality of the prepared peanut oil.

[0031] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
