Description

Technical Field

[0001] This invention belongs to the field of peanut oil processing technology, specifically a steam cooking device and pressing method for peanut oil raw embryos. Background Technology

[0002] Peanut oil processing involves steps such as raw material handling, pressing to extract oil, and refining. Among these steps, steaming the peanut embryos is a crucial pretreatment process.

[0003] Traditional peanut steaming involves first placing a small amount of water at the bottom of the steaming tank, then adding the raw peanuts and sealing the tank. A heating element heats the water at the bottom of the tank to generate steam for steaming. Operators typically install a stirring paddle inside the tank, driven by a motor at the bottom, to prevent the peanuts from sticking together during steaming. However, because the paddle rotates over solid peanuts, this significantly increases the motor's resistance and energy consumption. Furthermore, the high temperature and humidity of the steaming environment makes heat dissipation difficult for the motor, and the motor may be exposed to the surrounding hot steam, causing the insulation materials to age and deteriorate, potentially leading to electrical leakage risks.

[0004] Therefore, in order to solve the above problems, a steam cooking device and pressing method for peanut oil raw embryos are proposed. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a peanut oil raw material steam cooking device, which solves the problems of increased energy consumption and leakage risk caused by rotating the stirring blades in the cooking tank by driving the motor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a peanut oil raw embryo steam cooking device, comprising a cylinder, a support and a cover threadedly connected to the cylinder, wherein a heating pipe and a perforated plate are installed at the bottom of the cylinder cavity, and further comprising: a stirring paddle mechanism rotatably connected to the cylinder, wherein a driving mechanism is installed at the bottom of the cylinder. The driving mechanism includes an arc-shaped sleeve, a spring piston rod, and an annular track. The spring piston rod is movably sleeved inside the arc-shaped sleeve. One end of the spring piston rod extends to the outside of the arc-shaped sleeve and is fixedly connected to a hanger. Several hangers are fixedly sleeved on the outer periphery of the arc-shaped sleeve. Several ratchet teeth are arranged in annular array on the annular track, and the annular track is fixedly installed at the bottom of the cylinder. The top end of the hanger is slidably installed between the bottom surface of the cylinder and the upper surface of the annular track. The top end of the hanger is provided with a spring pawl that can cooperate with the ratchet teeth. A connecting rod is hinged to the bottom end of the hanger on the spring piston rod, and the other end of the connecting rod is connected to the bottom of the stirring paddle mechanism for transmission. A valve mechanism is provided at one end of the arc-shaped sleeve, and the cavity of the cylinder can be connected to the arc-shaped sleeve through the stirring paddle mechanism and the valve mechanism.

[0007] Preferably, the middle part of the cylinder is hinged to the top of the support, and a handle is fixedly connected to the middle part of the cylinder; a manual valve and a safety valve are provided on the cover.

[0008] Preferably, the valve mechanism includes a valve sleeve fixedly installed at one end of the arc-shaped sleeve, a valve core is rotatably connected inside the valve sleeve, a three-way pipe and a channel are opened inside the valve core, the channel can be connected to the arc-shaped sleeve cavity through the three-way pipe, an exhaust port is opened on the valve sleeve, and a connecting pipe is connected to the bottom of the valve sleeve and the stirring paddle mechanism. The cylindrical cavity is connected to the arc-shaped sleeve through a stirring paddle mechanism, connecting pipe, channel and tee pipe. Initially, both ends of the tee pipe are blocked by the valve sleeve. After the valve sleeve is rotated 90 degrees, both ends of the tee pipe can be connected to the arc-shaped sleeve and the exhaust port respectively, and one end in the middle is blocked. A lever is fixedly sleeved at the top of the valve core component. A tension spring is hinged to the top of the lever, and the other end of the tension spring is hinged to the top of the valve core component. An arc-shaped rod is fixedly connected to the hanger on the spring piston rod. When the spring piston rod extends, it can drive the arc-shaped rod to push the lever to rotate. When the arc-shaped rod returns to its original position, it can push the lever to rotate in the opposite direction.

[0009] Preferably, a set of limiting shafts that can abut against the lever are fixedly connected to the top of the valve core in a symmetrical direction, and the two limiting shafts can limit the rotation angle of the lever to ninety degrees.

[0010] Preferably, the arc-shaped rod is also movably mounted on the bottom of the annular track.

[0011] Preferably, an annular frame is fixedly installed inside the cylinder; the stirring paddle mechanism includes a transmission rod, several sleeve rods, a paddle blade, and a one-way spring pin. One end of the transmission rod extends to the bottom of the cylinder and is connected to the connecting rod for transmission. Several sleeve rods are sleeved outside the transmission rod. The paddle blade is rotatably connected to the outer periphery of two adjacent ends of the sleeve rod. Several sets of one-way spring pins are movably installed inside the paddle blade. Several sets of slots are vertically opened on the one-way spring pins. Initially, the one-way spring pins at the top can be engaged in the corresponding slots. When the transmission rod moves downward, the top set of one-way spring pins will disengage from the slots, and the bottom set of one-way spring pins will engage in the corresponding slots. When the transmission rod moves upward, it can press the one-way spring pin through the slot and disengage it. An adjustment mechanism for driving the transmission rod downward is installed at the bottom of the cylinder.

[0012] Preferably, the adjusting mechanism includes a sleeve fixedly installed at the bottom of the cylinder. The inner wall of the sleeve is provided with several sets of annular grooves at equal intervals. The inner wall of the sleeve is provided with an inclined groove for connecting two adjacent annular grooves. An inclined block is installed in the bottom set of annular grooves. A spring piston rod that can slide in the annular groove is movably installed at the bottom of the transmission rod. An elastic element is sleeved on the outer periphery of the transmission rod. The top and bottom ends of the elastic element abut against the transmission rod and the elastic element, respectively. The transmission rod has micro-holes, and the spring piston rod can move along the outer periphery of the inclined block and disengage from the annular groove, thereby pushing the spring piston rod to compress and store force to discharge the gas in the transmission rod through the micro-holes. The bottom end of the transmission rod is hexagonal prism-shaped and is movably fitted inside the connecting rod.

[0013] Preferably, one end of the connecting pipe is rotatably connected to the transmission rod.

[0014] A method for pressing peanut oil embryos, employing a steam-cooking device for peanut oil embryos, the pressing method being as follows: S1. After cleaning the peanut embryos, put them into the cylinder and cover them with the lid for steaming. The steam generated in the cylinder will enter the drive mechanism through the stirring paddle mechanism and valve mechanism, and drive the stirring paddle mechanism to rotate and stir the peanut embryos in the cylinder. S2. After steaming and cooking, manually rotate the manual valve to open and release the pressure inside the cylinder. Then, turn on the drive mechanism, use the handle to rotate the cylinder around the shaft, and pour the peanuts inside the cylinder onto the conveying equipment and transport them to the press. S3. The cooked peanut embryos are fed evenly and continuously into the pressing chamber of the screw press by a heat-resistant belt conveyor. The main screw shaft with a gradually decreasing pitch is used to push the peanut embryos forward, so that the peanut oil flows out through the gaps in the pressing cage.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The above solution introduces steam from the cylinder into the arc-shaped sleeve via the stirring paddle mechanism and valve mechanism. This drives the spring piston rod to move the hanger and, through the connecting rod, rotates the stirring paddle mechanism. The spring pawl on the hanger slides along the ratchet teeth. After the spring piston rod extends, the arc-shaped sleeve and the bottom of the stirring paddle mechanism are connected to the outside through the valve mechanism, allowing the internal gas to be discharged. At this time, the spring pawl on the spring piston rod is locked in the opposite direction with the ratchet teeth and cannot be reset. Under the action of the spring force on the spring piston rod, the arc-shaped sleeve is supported to move towards the spring piston rod. At this time, the spring pawl on the arc-shaped sleeve slides along the teeth until the spring piston rod retracts into the arc-shaped sleeve. Then, the valve mechanism connects the bottom of the stirring paddle mechanism with the arc-shaped sleeve. The above operation is repeated to drive the stirring paddle mechanism to rotate. By using a drive mechanism instead of a motor to drive the stirring paddle in the cooking tank, the energy consumption and leakage risk of the equipment are reduced. The above scheme uses a connecting rod to drive the bottom of the transmission rod to rotate. Initially, the one-way spring pin at the top will engage in the corresponding slot and drive the blade to rotate. After the transmission rod rotates one revolution, the adjusting mechanism will drive the transmission rod downward and force the slot to disengage from the corresponding one-way spring pin. The lower set of slots will then descend to the same height as the corresponding one-way spring pin, and under the action of the one-way spring pin's own elasticity, it will engage in the slot. At this time, the rotation of the transmission rod will drive the rotation of that set of blades, thus avoiding the situation where the drive mechanism cannot drive multiple sets of blades to rotate at the same time.

[0018] 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.

[0019] like Figures 1 to 12 As shown, the present invention provides a peanut oil raw embryo steam cooking device, including a cylinder 1, a support 11 and a cover 12 threadedly connected to the cylinder 1, and a heating tube 6 and a perforated plate 14 installed at the bottom of the cylinder 1 cavity. It also includes a stirring paddle mechanism 4 rotatably connected to the cylinder 1, and a driving mechanism 2 installed at the bottom of the cylinder 1. The drive mechanism 2 includes an arc-shaped sleeve 21, a spring piston rod 22, and an annular track 25. The spring piston rod 22 is movably sleeved inside the arc-shaped sleeve 21. One end of the spring piston rod 22 extends to the outside of the arc-shaped sleeve 21 and is fixedly connected to a hanger 23. Several hangers 23 are fixedly sleeved on the outer periphery of the arc-shaped sleeve 21. Several ratchet teeth 26 are arranged in annular array on the annular track 25. The annular track 25 is fixedly installed at the bottom of the cylinder 1. The top end of the hanger 23 is slidably installed between the bottom surface of the cylinder 1 and the upper surface of the annular track 25. The top end of the hanger 23 is provided with a spring pawl 24 that can cooperate with the ratchet teeth 26. A connecting rod 27 is hinged to the bottom end of the hanger 23 on the spring piston rod 22. The other end of the connecting rod 27 is connected to the bottom of the stirring paddle mechanism 4 for transmission. A valve mechanism 3 is provided at one end of the arc-shaped sleeve 21, and the cavity of the cylinder 1 can be connected to the arc-shaped sleeve 21 through the stirring paddle mechanism 4 and the valve mechanism 3; The middle part of the cylinder 1 is hinged to the top of the support 11, and a handle 13 is fixedly connected to the middle part of the cylinder 1; a manual valve 7 and a safety valve 8 are provided on the cover 12.

[0020] Using the above scheme, the steam inside the cylinder 1 rises and enters the arc-shaped sleeve 21 through the stirring paddle mechanism 4 and valve mechanism 3, thereby pushing the spring piston rod 22 to move the hanger 23 on it, and through the connecting rod 27, driving the stirring paddle mechanism 4 to rotate and stir. The spring pawls 24 on the hanger 23 will slide sequentially along the ratchet teeth 26. After the spring piston rod 22 extends, the bottom of the arc-shaped sleeve 21 and the stirring paddle mechanism 4 are connected to the outside through the valve mechanism 3, and the internal gas is discharged to the outside. At this time, the spring pawls 24 on the spring piston rod 22... When the claw 24 and ratchet 26 are locked in opposite directions and cannot be reset, the spring force on the spring piston rod 22 will support the arc sleeve 21 to move toward the spring piston rod 22. At this time, the spring claw 24 on the arc sleeve 21 will slide along the teeth until the spring piston rod 22 retracts back into the arc sleeve 21. Then, the valve mechanism 3 will connect the bottom of the stirring paddle mechanism 4 with the arc sleeve 21. Repeat the above operation to drive the stirring paddle mechanism 4 to rotate. The driving mechanism 2 replaces the motor to drive the stirring paddle in the cooking tank to rotate, thereby reducing equipment energy consumption and leakage risk. It is worth noting that the length of the blade part on the stirring paddle mechanism 4 is less than the length of the connecting rod 27. At the same time, the operator can increase the inner diameter of the arc sleeve 21 to ensure that the spring piston rod 22 can stably drive the stirring paddle mechanism 4 to rotate when it extends outward.

[0021] like Figures 1-7 As shown, the valve mechanism 3 includes a valve sleeve 31 fixedly installed at one end of the arc-shaped sleeve 21. A valve core 32 is rotatably connected inside the valve sleeve 31. A three-way pipe 33 and a channel 34 are provided inside the valve core 32. The channel 34 can communicate with the cavity of the arc-shaped sleeve 21 through the three-way pipe 33. An exhaust port 35 is provided on the valve sleeve 31. A connecting pipe 36 is connected to the bottom of the valve sleeve 31 and the stirring paddle mechanism 4. The cylinder 1 cavity is connected to the arc sleeve 21 through the stirring paddle mechanism 4, connecting pipe 36, channel 34 and three-way pipe 33. Initially, both ends of the three-way pipe 33 are blocked by the valve sleeve 31. After the valve sleeve 31 is rotated 90 degrees, both ends of the three-way pipe 33 can be connected to the arc sleeve 21 and the exhaust port 35 respectively, and one end in the middle is blocked. A lever 37 is fixedly sleeved on the top of the valve core 32. A tension spring 38 is hinged to the top of the lever 37, and the other end of the tension spring 38 is hinged to the top of the valve core 32. An arc-shaped rod 39 is fixedly connected to the hanger 23 on the spring piston rod 22. When the spring piston rod 22 extends, it can drive the arc-shaped rod 39 to push the lever 37 to rotate. When the arc-shaped rod 39 returns to its original position, it can push the lever 37 to rotate in the opposite direction. A set of limiting shafts 321 that can abut against the lever 37 are symmetrically fixed to the top of the valve core 32. The two limiting shafts 321 can limit the rotation angle of the lever 37 to ninety degrees; the arc-shaped rod 39 is also movably installed at the bottom of the annular track 25.

[0022] Using the above scheme, when the spring piston rod 22 is extended to its longest length, it will squeeze the lever 37 to be parallel to the tension spring 38 during rotation. Then the lever 37 continues to rotate. At this time, under the tension of the tension spring 38, the lever 37 is pulled to rotate rapidly. At this time, the two ends of the three-way pipe 33 are respectively connected to the arc sleeve 21 and the exhaust port 35, so that the gas at the arc sleeve 21 and the connecting pipe 36 can be discharged to the outside. Subsequently, the spring force on the spring piston rod 22 will push the arc sleeve 21 to move and gradually fit onto the spring piston rod 22. During this process, the arc sleeve 21 will drive the valve sleeve 31 to move, so that the lever 37 will abut against the other end of the arc rod 39 and rotate the lever 37 in the opposite direction by ninety degrees. At this time, both ends of the three-way pipe 33 are blocked, and one end in the middle will be connected to the arc sleeve 21. The gas in the connecting pipe 36 will enter the arc sleeve 21 through the channel 34 and the three-way pipe 33.

[0023] like Figures 2-3 and Figures 8-10 As shown, an annular frame 15 is fixedly installed inside the cylinder 1; the stirring paddle mechanism 4 includes a transmission rod 42, several sleeve rods 41, a blade 43 and a one-way spring pin 44. One end of the transmission rod 42 extends to the bottom of the cylinder 1 and is connected to the connecting rod 27. Several sleeve rods 41 are sleeved on the outside of the transmission rod 42. The blade 43 is rotatably connected to the outer periphery of the adjacent ends of two sleeve rods 41. Several sets of one-way spring pins 44 are movably installed inside the blade 43. Several sets of slots 45 are vertically opened on the one-way spring pins 44. Initially, the one-way spring pin 44 at the top can be engaged in the corresponding slot 45. When the transmission rod 42 moves downward, the top set of one-way spring pins 44 will disengage from the slot 45, and the bottom set of one-way spring pins 44 will engage in the corresponding slot 45. When the transmission rod 42 moves upward, it can squeeze the one-way spring pins 44 through the slot 45 and disengage them. An adjustment mechanism 5 for driving the transmission rod 42 downward is installed at the bottom of the cylinder 1; Using the above scheme, the bottom of the transmission rod 42 is rotated by the connecting rod 27. Initially, the one-way spring pin 44 at the top will be engaged in the corresponding slot 45 and drive the blade 43 to rotate. After the transmission rod 42 rotates one revolution, the adjusting mechanism 5 will drive the transmission rod 42 downward and force the slot 45 to squeeze the corresponding one-way spring pin 44 to disengage. The lower set of slots 45 will descend to the same height as the corresponding one-way spring pin 44. Under the action of the elastic force of the one-way spring pin 44, it will be engaged in the slot 45. At this time, the rotation of the transmission rod 42 will drive the blade 43 to rotate, thereby avoiding the situation where the drive mechanism 2 cannot drive multiple sets of blades 43 to rotate at the same time. After the transmission rod 42 drives the bottommost blade 43 to rotate one revolution, the transmission rod 42 will reset and move upward, causing the one-way spring pin 44 at the top to re-engage into the corresponding slot 45.

[0024] like Figures 1-3 and Figures 10-12 As shown, the adjusting mechanism 5 includes a sleeve 51 fixedly installed at the bottom of the cylinder 1. The inner wall of the sleeve 51 is provided with several sets of annular grooves 52 at equal intervals. The inner wall of the sleeve 51 is provided with a slanted groove 53 for connecting two adjacent annular grooves 52. A slanted block 54 is installed in the bottom set of annular grooves 52. A spring piston rod 56 that can slide in the annular groove 52 is movably installed at the bottom of the transmission rod 42. An elastic element 55 is sleeved on the outer periphery of the transmission rod 42. The top and bottom ends of the elastic element 55 abut against the transmission rod 42 and the elastic element 55, respectively. The transmission rod 42 has a micro-hole 421. The spring piston rod 56 can move along the outer periphery of the inclined block 54 and disengage from the annular groove 52, thereby pushing the spring piston rod 56 to compress and store force to discharge the gas in the transmission rod 42 through the micro-hole 421. The bottom end of the transmission rod 42 is hexagonal prism and is movably sleeved in the connecting rod 27. One end of the connecting pipe 36 is rotatably connected to the transmission rod 42. Using the above scheme, during the rotation of the transmission rod 42, it will drive the spring piston rod 56 to rotate in the annular groove 52. After one rotation, the spring piston rod 56 will enter the next annular groove 52 along the inclined groove 53, thereby causing the transmission rod 42 to move downward and the elastic element 55 to compress and store force. When the spring piston rod 56 moves along the inclined block 54 and disengages from the annular groove 52, it will push the transmission rod 42 upward under the action of the elastic force of the elastic element 55 and drive the spring piston rod 56 upward. When the spring piston rod 56 is reset, the micro-hole 421 will restrict the entry of gas, thereby slowing down the reset speed of the spring piston rod 56. Since the connecting rod 27 drives the transmission rod 42 to rotate, when the transmission rod 42 moves to the top, the spring piston rod 56 will reset and lock into the annular groove 52 at the top, thus repeating the above work.

[0025] Working principle and usage process of this invention: During the steaming of peanut embryos, the water source at the bottom of the cylinder 1 is heated by the heating pipe 6 to generate steam. The steam rises and enters the arc-shaped sleeve 21 through the stirring paddle mechanism 4 and the valve mechanism 3, thereby pushing the spring piston rod 22 to move the hanger 23 on it. Through the connecting rod 27, the stirring paddle mechanism 4 is rotated and stirred. The spring pawls 24 on the hanger 23 slide sequentially along the ratchet teeth 26. When the spring piston rod 22 is fully extended, the bottom of the arc-shaped sleeve 21 and the stirring paddle mechanism 4 are connected to the outside through the valve mechanism 3. The valve mechanism 3 connects the valve to the bottom of the stirring paddle mechanism 4 and the arc sleeve 21, and repeats the above operation to drive the stirring paddle mechanism 4 to rotate. At this time, the spring pawl 24 on the spring piston rod 22 is locked in the opposite direction with the ratchet 26 and cannot be reset. Under the action of the spring force on the spring piston rod 22, the arc sleeve 21 will be supported to move towards the spring piston rod 22. At this time, the spring pawl 24 on the arc sleeve 21 will slide along the teeth until the spring piston rod 22 retracts into the arc sleeve 21. Then the valve mechanism 3 connects the bottom of the stirring paddle mechanism 4 with the arc sleeve 21. The above operation is repeated to drive the stirring paddle mechanism 4 to rotate. The rotation of the connecting rod 27 drives the bottom of the transmission rod 42 to rotate. Initially, the one-way spring pin 44 at the top will engage in the corresponding slot 45 and drive the blade 43 to rotate. After the transmission rod 42 rotates one revolution, the adjusting mechanism 5 will drive the transmission rod 42 downward and force the slot 45 to disengage the corresponding one-way spring pin 44. The lower set of slots 45 will descend to the same height as the corresponding one-way spring pin 44. Under the action of the elastic force of the one-way spring pin 44, it will engage in the slot 45. At this time, the rotation of the transmission rod 42 will drive the blade 43 to rotate, thereby avoiding the situation where the drive mechanism 2 cannot drive multiple sets of blades 43 to rotate at the same time. After the transmission rod 42 drives the bottom blade 43 to rotate one revolution, the transmission rod 42 will reset and move upward and re-engage the one-way spring pin 44 at the top into the corresponding slot 45.
