Description

Technical Field

[0001] This invention pertains to chestnut processing equipment, specifically a chestnut stir-frying device for removing internal stress. Background Technology

[0002] Chestnuts are nuts rich in carbohydrates and can be eaten raw or cooked. When cooked, chestnuts are usually roasted or boiled to make them soft, sweet, and juicy.

[0003] For example, Chinese Patent (CN222322767U) discloses a chestnut processing and stir-frying device in its specification, including an attachment plate. A rotating stir-frying mechanism is movably arranged on one side of the attachment plate. The rotating stir-frying mechanism includes a guide groove, a traction rod, a movable rotating rod, and a movable bearing. The guide groove is opened inside the attachment plate, and the traction rod is movably arranged inside the guide groove. A movable rotating rod is movably arranged inside the traction rod on one side of the attachment plate. A movable bearing is movably arranged on one side of the outer circumference of the movable rotating rod. The movable rotating rod passes through the inner ring of the movable bearing. One side of the traction rod is fixedly connected to the outer ring of the movable bearing. A lifting and adjusting mechanism is fixedly arranged on the side of the attachment plate away from the movable bearing. The lifting and adjusting mechanism includes a control panel, a hollow sleeve plate, a snap-fit ​​groove, and a positioning snap. The control panel is fixedly arranged on the side of the attachment plate away from the movable bearing. A hollow sleeve plate is movably arranged at the bottom of the control panel. A snap-fit ​​groove is opened on the outside of the hollow sleeve plate, and a positioning snap is movably arranged inside the snap-fit ​​groove. The positioning snap passes through the snap-fit ​​groove and is movably connected to the inside of one side of the control panel.

[0004] Furthermore, Chinese Patent (CN221769267U) discloses a chestnut stir-frying device in its specification, including a base. Support plates are fixedly connected to both sides of the upper surface of the base. Two connecting plates are symmetrically fixedly connected to the outer surfaces of the two support plates that are close to each other. A stir-frying cylinder for stir-frying chestnuts is fixedly connected to one end of the four connecting plates. A stir-frying mechanism is installed through the inside of the stir-frying cylinder. A quartz sand recovery mechanism connected to the stir-frying cylinder is fixedly installed on the upper surface of the base. A chestnut screening mechanism is fixedly connected to the top of the quartz sand recovery mechanism. The stir-frying mechanism includes a drive motor fixedly installed on one side of the outer surface of the support plate. A rotating shaft is fixedly connected to the output shaft of the drive motor. The rotating shaft passes through the support plate and the stir-frying cylinder and is rotatably connected to the support plate and the stir-frying cylinder. Multiple stir-frying plates are fixedly connected to the outer surface of the rotating shaft in sequence.

[0005] As can be seen, the aforementioned device can stir-fry chestnuts, but it cannot remove the internal stress generated by the stir-frying process. Furthermore, although the chestnuts are pre-opened before stir-frying, the flesh expands during cooking, widening the opening and causing the flesh to adhere to the shell. Therefore, peeling the chestnuts from the opening usually requires tearing the shell to easily remove the flesh. Thus, to address the shortcomings of the existing technology, a chestnut stir-frying device that facilitates easy peeling and removes internal stress has been developed. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, this disclosure discloses a chestnut stir-frying device for removing internal stress, including a stir-frying cylinder, an electric heater 11, a first rotating shaft 5, a feeding hopper 7, a sealing door 9, a striking mechanism, a discharge chute 12, a controller 31, a motor frame 2, a first bearing 4, and a first support 1. The stir-frying cylinder is installed on the first support 1, and is horizontally and inclined downwards. The stir-frying cylinder includes an inner cylinder 29 and an outer cylinder 8. The outer cylinder 8 is fitted inside the inner cylinder 29. One end of the inner cylinder 29 and the outer cylinder 8 are connected by a first sealing plate 32, and the other end is connected by a second sealing plate 33. The second sealing plate 33 has a discharge port communicating with the inner cylinder 29. The electric heater 11 is wound around the inner cylinder 29. One end of the first rotating shaft 5 is rotatably connected to the bearing seat support 34 installed on the inner cylinder 29, and the other end passes through the first sealing plate 32 and is driven by the first drive motor 3. The first rotating shaft 5 and the first bearing 4 are connected to the first drive motor 3. A sealing plate 32 is connected via a first bearing 4, and a first rotating shaft 5 located inside the inner cylinder 29 is equipped with a spiral blade 6 along its length. A first drive motor 3 is mounted on a motor frame 2, and the motor frame 2 is mounted on a first bracket 1. A feed hopper 7 extends through an outer cylinder 8 and inserts into the inner cylinder 29. A sealing door 9 is movably closed at the discharge port. A striking mechanism is provided with an inlet 281. One end of the discharge trough 12 is installed below the discharge port, and the other end extends to the inlet 281. A controller 31 has an intelligent display screen and is electrically connected to the first drive motor 3, the electric heater 11, and the striking mechanism.

[0031] The bearing housing bracket 34 is equipped with a bearing housing 10, which is connected to the first rotating shaft 5. The bearing housing 10 supports the first rotating shaft 5 to rotate smoothly.

[0032] The controller 31 can be used to control the operation of the first drive motor 3, the electric heater 11, and the striking mechanism.

[0033] The power of the electric heater can range from 1.5 to 15 kilowatts. The appropriate power can be selected based on the amount of chestnuts to be roasted. For example, selectable power options include 1.5, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 kilowatts. Understandably, the operating power of the electric heater can be adjusted via a controller.

[0034] The electric heater 11 includes a heating wire wound around the inner cylinder 29 for heating the inner cylinder 29. The heating temperature of the inner cylinder 29 is 150℃ to 250℃. During stir-frying, the required temperature for stir-frying in the inner cylinder can be 150℃, 160℃, 170℃, 180℃, 190℃, 200℃, 210℃, 220℃, 230℃, 240℃, or 250℃, etc. Of course, the temperature of the inner cylinder is not limited to these; a suitable temperature can be selected as needed.

[0035] The stir-frying cylinder is horizontal and installed at a downward tilt, with an angle of 3 to 5 degrees, such as 3°, 4° or 5°.

[0036] Understandably, the installation height of the feed hopper 7 is higher than the discharge port. During stir-frying, the first drive motor drives the first rotating shaft to rotate in the opposite direction, which in turn drives the spiral blades to rotate. The spiral blades move the chestnuts in the inner cylinder towards the feed hopper. When they reach the end face, the spiral blades continuously push the chestnuts in. Because the stir-frying cylinder is tilted, the chestnuts roll towards the discharge port, allowing the chestnuts to circulate within the inner cylinder, which helps to ensure even heating of the chestnuts. When stir-frying is finished and the chestnuts need to be discharged, the controller controls the first drive motor to rotate in the forward direction when the sealing door is opened, and the spiral blades push the chestnuts out of the discharge port, thus discharging the chestnuts.

[0037] like Figure 1 , 5 As shown, the striking can 28 is mounted on the support frame 27, which can stably support the striking can 28.

[0038] like Figure 1 , 2 As shown, a temperature sensor 30 is installed on the outer cylinder 8. The outer cylinder is fitted into the inner cylinder, so that a sandwich space is formed between the two cylinders. The temperature sensor can be used to measure the temperature in the sandwich space. The measured temperature data is transmitted to the controller, which can display it on the intelligent display screen, so as to easily know the stir-frying temperature.

[0039] It should be noted that during stir-frying, the inner cylinder can be heated to produce round or oval-shaped quartz sand or black sand. The amount of quartz sand or black sand added can be adjusted according to the weight of the chestnuts being stir-fried. For example, the ratio of chestnuts to quartz sand during stir-frying can be 1:1.5 to 2.5, and ratios such as 1:1.5, 1:2, or 1:2.5 can be used, depending on the weight of the chestnuts being stir-fried.

[0040] In some alternative embodiments, one structure of the striking mechanism is provided. For example... Figure 1 , 5As shown in Figure 6, the striking mechanism includes a striking tank 28, a second rotating shaft 24, and a discharge component. The striking tank 28 has an inlet 281 at the top and an outlet at the bottom. One end of the second rotating shaft 24 is placed inside the striking tank 28, and multiple rubber rods 23 are installed at circumferential offsets along its length. The other end passes through the top surface of the striking tank 28 and is connected to the second drive motor 13. The discharge component is installed at the outlet and is used to open and close the outlet.

[0041] The glue rod is a food-grade glue rod; for example, a food-grade silicone rod can be used. It possesses good elasticity and toughness, enabling it to buffer impact through deformation and achieve flexible contact. Understandably, when the glue rod rotates and strikes the chestnut, it makes flexible contact with the chestnut, avoiding rigid collisions and significantly reducing the amount of breakage caused by the impact.

[0042] The second drive motor 13 can be electrically connected to the controller 31. The controller can control the operating time of the second drive motor, thereby controlling the duration for which the second rotating shaft drives multiple rubber rods to strike. For example, the striking time can be set to 3 to 10 minutes, but it is not limited to this; an appropriate time can be selected according to the number of chestnuts being struck.

[0043] The controller 31 can adjust the speed of the second drive motor, and the speed can be adjusted according to the impact effect. For example, the motor speed can be 100-150 RPM. Of course, it is not limited to this; an appropriate motor speed can be selected according to the working requirements.

[0044] Work style:

[0045] The second drive motor 13 drives the second rotating shaft 24 to rotate, and the second rotating shaft 24 drives the multiple rubber rods 23 installed on it to rotate. The chestnuts after being stir-fried enter the striking tank 28 through the feed inlet 281. The rotating multiple rubber rods 23 strike and agitate the chestnuts that enter. The chestnuts that are struck and fly away collide with the inner side of the striking tank. After multiple collisions, the chestnut meat and shell can be loosened, which can facilitate the separation of the kernel and shell when peeling.

[0046] When the set time is reached (for example, the set time is 3, 4 or 5 minutes), the second drive motor stops working, the second rotating shaft and multiple rubber rods stop rotating, the unloading part is opened, the discharge port at the bottom of the striking tank is open, and the chestnuts in the striking tank can be discharged through the discharge port; after the chestnuts are discharged, the unloading part is reset and closed at the discharge port, and the discharge port is closed.

[0047] It should be noted that the bottom of the discharge trough 12 has a mesh structure, which is used to filter the quartz sand or black sand added during stir-frying. This prevents the quartz sand or black sand from entering the impact tank.

[0048] In some alternative embodiments, one structure of the unloading component is provided. The unloading component includes a second support rod 26, a sealing plate 22, a connecting plate 21, a telescopic drive component 19, and a first support rod 16. The second support rod 26 is inclined downward; one end of the sealing plate 22 is connected to one end of the diagonal brace 25, and the other end of the diagonal brace 25 is hinged to the second support rod 26; one end of the connecting plate 21 is connected to the other end of the sealing plate 22; the telescopic drive component 19 is provided with a piston 191, and the piston 191 is hinged to the connecting plate 21; the first support rod 16 is hinged to the telescopic drive component 19.

[0049] One structure of the telescopic drive component 19 can be an electric push rod.

[0050] The second support rod 26 is installed on the outer circumferential side of the striking can 28 and is tilted downward.

[0051] One end of the diagonal brace 25 is provided with a U-shaped seat, and the other end is connected to the end plate 22. The diagonal brace is inclined relative to the end plate. During installation, the U-shaped seat on the diagonal brace is fitted onto the lower end of the second support rod 26, and the U-shaped seat and the second support rod 26 are connected by a pin, so that the second support rod 26 and the diagonal brace can be oscillatingly connected.

[0052] The first support rod 16 is installed on the outer circumferential side of the striking can 28 and is inclined downward. A first U-shaped seat 17 is installed on the telescopic drive member 21. The first U-shaped seat 17 is fitted onto the lower end of the first support rod 16. A first shaft 18 passes through the first U-shaped seat 17 and the first support rod 16. The first support rod 16 and the telescopic drive member 21 are rotatably connected by the first shaft 18. The telescopic drive member can swing relative to the first support rod 16.

[0053] The second U-shaped seat 20 is installed on the connecting plate 21 and fitted onto one end of the piston 191. A short shaft passes through the second U-shaped seat and the piston 191. The piston can swing relative to the second U-shaped seat with the help of the short shaft.

[0054] In some alternative embodiments, in order to cool the chestnuts entering the impact tank, at least one nitrogen pipe 14 is added, which is connected to the impact tank 28 and is equipped with a control valve 15 for conveying liquid nitrogen at a temperature of -200°C to -195°C.

[0055] The number of nitrogen liquid pipes installed can be one or two, etc. Liquid nitrogen is transported within the nitrogen liquid pipes. When control valve 15 is opened, the liquid nitrogen in the nitrogen liquid pipes is sprayed into the impact tank. The liquid nitrogen absorbs a large amount of heat and rapidly evaporates, carrying away the heat and quickly reducing the temperature of the impact tank and the chestnuts inside, thus achieving rapid cooling of the chestnuts. The vaporization of the liquid nitrogen produces a large amount of nitrogen gas, which fills the impact tank, thereby expelling the air inside the impact tank and effectively reducing oxidation of the chestnuts during the impact process.

[0056] When installing the nitrogen liquid pipe, it can be installed close to the bottom of the impact tank. Nitrogen gas can enter from the bottom of the impact tank and then exit from the inlet of the impact tank.

[0057] It should be noted that the liquid nitrogen in the nitrogen pipe can be supplied by a liquid nitrogen tank. It is understood that the liquid nitrogen tank is an insulated tank.

[0058] Understandably, introducing liquid nitrogen into the striking vessel can rapidly cool the chestnuts inside, causing the chestnut shells to cool quickly and become brittle. The striking vessel also contains a second rotating shaft 24, which drives multiple rubber rods 23 mounted on it to rotate. These rods strike the chestnuts placed inside the striking vessel, causing them to collide (e.g., between chestnuts, or between chestnuts and the side of the striking vessel), eliminating internal stress in the chestnut shells and further brittlening them, making them easier to peel.

[0059] In some optional embodiments, one structure of the sealing member is provided. The sealing member 9 includes a sealing plate 91, a second shaft seat 93, a third shaft seat 99, a fifth shaft seat 911, and a locking rod 96. The sealing plate 91 has a first shaft seat 92 on one side and a fourth shaft seat 910 on the other side; the second shaft seat 93 is installed on the second sealing plate 33 and connected to the first shaft seat 92 through a support shaft 94; the third shaft seat 99 and the fifth shaft seat 911 are vertically spaced on the second sealing plate 33; the fourth shaft seat 910 is oscillating between the third shaft seat 99 and the fifth shaft seat 911, and the locking rod 96 passes through the third shaft seat 99, the fourth shaft seat 910, and the fifth shaft seat 911 in sequence.

[0060] Understandably, the first bearing seat 92, the second bearing seat 93, the third bearing seat 99, the fourth bearing seat 910, and the fifth bearing seat 911 are all provided with shaft through holes.

[0061] The sealing plate 91 can swing with the help of the first bearing 92, the second bearing 93 and the support shaft 94.

[0062] How the door sealing component works:

[0063] Closing operation: The sealing plate 91 can swing relative to the outer cylinder 8 with the help of the first shaft seat 92, the second shaft seat 93 and the support shaft 94. The swinging is until the sealing plate 91 fits against the discharge port of the inner cylinder, thus closing the discharge port. At this time, the fourth shaft seat 910 swings between the third shaft seat 99 and the fifth shaft seat 911. The locking rod 96 passes through the third shaft seat 99, the fourth shaft seat 910 and the fifth shaft seat 911 in sequence. Then the locking rod 96 is inserted into the third shaft seat 99, the fourth shaft seat 910 and the fifth shaft seat 911 in sequence, and the sealing plate is restricted to close at the discharge port.

[0064] When the machine is turned on, the locking rod 96 is pulled out, the fourth shaft seat 910 is unlocked, and the sealing plate 91 can swing outward with the help of the first shaft seat 92, the second shaft seat 93 and the support shaft 94 to open the discharge port, so that the chestnuts stir-fried in the inner cylinder 29 can be discharged outward through the discharge port.

[0065] In some alternative embodiments, when the sealing plate is closed, a spring 98 is added to maintain the engagement between the locking rod and the third shaft seat 99, the fourth shaft seat 910, and the fifth shaft seat 911. The spring 98 is fitted onto the locking rod 96, with one end connected to the third shaft seat 99 and the other end connected to the locking rod 96.

[0066] When the sealing plate 91 is to be closed at the discharge port, the locking rod 96 is first pulled upward so that the locking rod is disengaged from the gap between the third shaft seat 99 and the fifth shaft seat 911, so as to prevent the locking rod 96 from obstructing the fourth shaft seat 910 from being inserted between the third shaft seat 99 and the fifth shaft seat 911. At this time, the spring is stretched upward to produce elastic deformation and has elastic deformation potential energy.

[0067] It should be noted that the locking rod 96 can be moved upwards and housed in the shaft through hole of the third shaft seat 99. When releasing the locking rod, the shaft through hole of the third shaft seat 99 can be used as a guide to facilitate the insertion of the locking rod into the fourth shaft seat 910 and the fifth shaft seat 911.

[0068] When the fourth bearing seat 910 is positioned between the third bearing seat 99 and the fifth bearing seat 911, the through holes on the third bearing seat 99, the fourth bearing seat 910, and the fifth bearing seat 911 are aligned with each other. Upon releasing the locking rod, the locking rod is subjected to the elastic deformation force of the spring, pulling it downwards. The locking rod extends from the third bearing seat 99 and sequentially inserts into the fourth bearing seat 910 and the fifth bearing seat 911. The spring restricts the locking rod, preventing it from disengaging from the third bearing seat 99, the fourth bearing seat 910, and the fifth bearing seat 911.

[0069] In some alternative embodiments, a handle 95 is provided on the sealing plate 91 to facilitate movement of the sealing plate. When the sealing plate is released from its restraint, the worker can swing the sealing plate by grasping the handle.

[0070] To facilitate the movement of the locking bar, a handle 97 is added and installed on the locking bar 96. The handle 97 allows the locking bar to be moved vertically.

[0071] The above-described embodiments are preferred embodiments of the present invention and are only used to facilitate the illustration of the present invention. They are not intended to limit the present invention in any way. Any person skilled in the art who makes local modifications or alterations to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention shall still fall within the scope of the technical features of the present invention.
