The equidistant distribution of the L-bars ensures that the stirring range covers the entire tank space, and combined with the pushing function of the disc, it can quickly concentrate the raw materials to the discharge port, reducing residue in the tank.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides a technical solution: including a base plate 1, two support plates 2 are fixedly connected to the top of the base plate 1, a stir-frying pot 3 is fixedly connected between the tops of the two support plates 2, a connecting shaft 4 is rotatably connected to one end of the inner wall of the stir-frying pot 3, L rods 5 are fixedly connected at equal intervals to one end of the connecting shaft 4, a disc 6 is slidably connected between multiple L rods 5, a heating groove 7 is opened inside the stir-frying pot 3, heating tubes 8 are installed and connected at equal intervals inside the heating groove 7, a first cylinder 9 is fixedly connected to one end of the stir-frying pot 3, the piston rod of the first cylinder 9 is rotatably connected to the disc 6, and a feeding hopper 10 is fixedly connected to the top of the stir-frying pot 3.
[0027] In this embodiment, during operation, flaxseed raw materials are first fed into the stir-frying tank 3 through the feeding hopper 10. The servo motor 25 is then started, and its output shaft drives the connecting shaft 4 to rotate at a constant speed. Multiple L-shaped rods 5 fixed on the connecting shaft 4 rotate synchronously with the shaft, using the rods to stir and fry the flaxseeds, preventing the raw materials from accumulating and clumping. Simultaneously, heating tubes 8, equidistantly installed in the heating groove 7 on the inner wall of the stir-frying tank 3, are energized and generate heat, transferring heat to the flaxseeds inside through the tank wall. This achieves a synergistic effect of "heating and frying simultaneously," ensuring that the flaxseeds are heated evenly and thoroughly, achieving the effect of softening the raw materials and activating the oil activity. After the frying process is completed, the first cylinder 9 is started, and its piston rod extends and retracts, pushing the disc 6 to slide axially along the L-shaped rod 5. The thrust of the disc 6 is used to push the frying flaxseeds towards the discharge chute 13, preparing for subsequent discharge.
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a pressing box 17 is fixedly connected to one side of one of the support plates 2 and below the stir-frying tank 3. A sliding plate 18 is slidably connected inside the pressing box 17. One end of the sliding plate 18 extends to the outside of the pressing box 17. An extrusion plate 26 is fixedly connected to the top of the sliding plate 18 and inside the pressing box 17. A baffle plate 20 is fixedly connected to the top of the extrusion plate 26 and above the pressing box 17.
[0029] In this embodiment, after being roasted, the flax seeds are discharged from the discharge chute 13 and fall onto the slide plate 18 inside the pressing chamber 17. One end of the slide plate 18 extends to the outside of the pressing chamber 17 and its position can be adjusted as needed to easily receive the raw materials. The baffle plate 20 fixed at its top extends vertically upward, effectively preventing the flax seeds from falling from the edge of the slide plate 18 and ensuring that the raw materials are concentrated in the pressing area. In addition, the mesh or gauze laid inside the pressing chamber 17 and above the slide plate 18 uses its fine structure to gather the dispersed flax seeds into a relatively compact pile, preventing the raw materials from scattering in all directions during pressing and making the squeezing force more concentrated on the raw materials themselves. Once the raw materials are in place, the extrusion plate 26 moves downward, and in conjunction with the gathering effect of the mesh / gauze, the flax seeds are efficiently pressed.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a collection cover 22 is fixedly connected to the bottom of the pressing box 17, and a filter screen 19 is fixedly connected between the collection cover 22 and the pressing box 17. Fixing plates 24 are fixedly connected to both sides of the bottom of the pressing box 17 and to the bottom plate 1.
[0031] In this embodiment, when the flaxseed is pressed by the extrusion plate 26 inside the pressing chamber 17, the extruded oil mixed with a small amount of fine residue passes through the filter screen 19 between the bottom of the pressing chamber 17 and the collection hood 22. The mesh of the filter screen 19 can intercept solid residue, allowing pure oil to permeate into the collection hood 22 below. The collection hood 22 has a funnel-shaped structure, using gravity to collect the oil to the bottom oil pipe 23, and finally discharge it to an external oil storage device through the bottom oil pipe 23. At the same time, the fixing plates 24 fixed between the bottom sides of the pressing chamber 17 and the bottom plate 1 enhance the overall stability of the pressing chamber 17 through rigid connection, preventing the device from shifting or components from loosening due to vibration during pressing.
[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, two third cylinders 21 are fixedly connected to the outside of the pressing box 17. The piston rods of the third cylinders 21 are fixedly connected to the extrusion plate 26. The bottom of the collecting cover 22 is fixedly connected to the lower oil pipe 23.
[0033] In this embodiment, after the flax seeds are gathered and positioned on the mesh / gauze inside the pressing box 17, the two third cylinders 21 fixed to the outside of the pressing box 17 are activated. Their piston rods extend and retract synchronously downwards, driving the top-connected extrusion plate 26 to move vertically downwards. After the extrusion plate 26 contacts the flax seed pile on the slide plate 18, as the cylinder thrust gradually increases, a continuous and uniform extrusion force is applied to the flax seeds, causing the oil to be extracted from the cells. The extruded oil is filtered sequentially through the filter screen 19, collected by the collection hood 22, and finally discharged and collected through the lower oil pipe 23. After pressing is completed, the piston rod of the third cylinder 21 retracts, driving the extrusion plate 26 to reset, facilitating the cleaning of residue.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a discharge trough 13 is provided at the bottom of the stir-frying tank 3 and above the pressing box 17. A discharge plate 15 is slidably connected inside the discharge trough 13, and a limit strip 16 is fixedly connected to the bottom of the discharge plate 15.
[0035] In this embodiment, the discharge trough 13 at the bottom of the stir-frying tank 3 is the channel through which flaxseeds enter the pressing process from the stir-frying process. The discharge plate 15, which is slidably connected inside, can open and close the trough by sliding: when the discharge plate 15 completely blocks the discharge trough 13, the flaxseeds are stir-fried inside the tank; when discharge is required, the discharge plate 15 is slid to partially or completely detach from the trough, and the flaxseeds fall from the discharge trough 13 into the pressing box 17 under the action of gravity and the thrust of the disc 6. A limiting strip 16 fixed to the bottom of the discharge plate 15 is engaged with the outer wall of the stir-frying tank 3, which limits the sliding stroke of the discharge plate 15, preventing it from completely falling out of the discharge trough 13 and ensuring operational safety.
[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a second cylinder 11 is fixedly connected to one side of the stir-frying tank 3 and below the first cylinder 9. A connecting plate 12 is fixedly connected to the piston rod of the second cylinder 11. A connecting rod 14 is fixedly connected to one side of the connecting plate 12 and below the second cylinder 11. The connecting rod 14 is fixedly connected to the discharge plate 15. A servo motor 25 is fixedly connected to the outside of the stir-frying tank 3. The output shaft of the servo motor 25 is fixedly connected to the connecting shaft 4.
[0037] In this embodiment, during discharge, the second cylinder 11 on one side of the stir-frying tank 3 is activated, and its piston rod extends and retracts, causing the connecting plate 12 to move horizontally. The connecting rod 14 fixed below the connecting plate 12 moves in sync, thereby pulling or pushing the discharge plate 15 to slide in the discharge trough 13, realizing the automatic opening and closing of the discharge trough 13, replacing manual operation. The output shaft of the servo motor 25 fixed on the outside of the stir-frying tank 3 is rigidly connected to the connecting shaft 4. Through the precise speed control of the motor, the connecting shaft 4 and the L rod 5 are driven to rotate at a set speed, ensuring that the flax seeds are stir-fried evenly and the time is controllable, avoiding over-stirring or under-stirring.
[0038] Working principle:
[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, during operation, flaxseed raw materials are first fed into the roasting tank 3 through the feeding hopper 10. The servo motor 25 is then started, and its output shaft drives the connecting shaft 4 to rotate at a constant speed. Multiple L-shaped rods 5 fixed on the connecting shaft 4 rotate synchronously with the shaft, using the rods to stir and roast the flaxseeds, preventing the raw materials from piling up and clumping. At the same time, heating tubes 8, which are equidistantly installed in the heating groove 7 on the inner wall of the roasting tank 3, are energized and generate heat. The heat is transferred to the flaxseeds inside through the tank wall, achieving a synergistic effect of "heating and roasting simultaneously," ensuring that the flaxseeds are heated evenly and fully, achieving the effect of softening the raw materials and activating the activity of the oils. After the roasting process is completed, the first cylinder 9 is started, and its piston rod extends and retracts to push the disc 6 to slide along the axial direction of the L-shaped rod 5. The thrust of the disc 6 is used to push the roasted flaxseeds towards the discharge chute 13, preparing for subsequent discharge. After being discharged from the discharge chute 13, the roasted flaxseeds fall onto the slide plate 18 inside the pressing box 17. One end of the slide plate 18 extends to the outside of the pressing box 17, and its position can be adjusted as needed to facilitate the receiving of raw materials. The top of the slide plate 18 has a fixed baffle plate 20 that extends vertically upwards, effectively preventing flax seeds from falling from the edge of the slide plate 18 and ensuring that the raw materials are concentrated in the pressing area. Furthermore, the mesh or gauze laid inside the pressing box 17 and above the slide plate 18 uses its fine structure to gather the dispersed flax seeds into a relatively compact pile, preventing the raw materials from scattering during pressing and concentrating the pressing force on the raw materials themselves. Once the raw materials are in place, the pressing plate 26 moves downwards, working in conjunction with the gathering effect of the mesh / gauze to efficiently press the flax seeds.
[0040] When the flaxseed is pressed by the extrusion plate 26 inside the pressing chamber 17, the squeezed oil mixed with a small amount of fine residue passes through the filter screen 19 between the bottom of the pressing chamber 17 and the collection hood 22. The mesh of the filter screen 19 can intercept solid residue, allowing pure oil to permeate into the collection hood 22 below. The collection hood 22 has a funnel-shaped structure, which uses gravity to collect the oil to the bottom oil pipe 23, and finally discharges it to the external oil storage device through the bottom oil pipe 23. At the same time, the fixing plates 24 fixed between the bottom sides of the pressing chamber 17 and the bottom plate 1 enhance the overall stability of the pressing chamber 17 through rigid connection, and prevent the device from shifting or the parts from loosening due to vibration during pressing. After the flaxseed is gathered and positioned on the mesh / cloth inside the pressing chamber 17, the two third cylinders 21 fixed on the outside of the pressing chamber 17 are activated, and their piston rods extend and retract downwards in sync, driving the extrusion plate 26 connected at the top to move vertically downwards. After the extrusion plate 26 contacts the flaxseed pile on the slide plate 18, as the cylinder thrust gradually increases, a continuous and uniform extrusion force is applied to the flaxseed, causing the oil to be extracted from the cells. The extruded oil is filtered through the filter screen 19, collected by the collection hood 22, and finally discharged and collected through the lower oil pipe 23. After pressing is completed, the piston rod of the third cylinder 21 retracts, driving the extrusion plate 26 to reset, which facilitates the cleaning of residues. The discharge trough 13 at the bottom of the stir-frying tank 3 is the channel for flaxseed to enter the pressing process from the stir-frying process. The discharge plate 15 inside it can be slidably connected to open and close the trough opening: when the discharge plate 15 completely blocks the discharge trough 13, the flaxseed is stir-fried in the tank; when discharge is required, the discharge plate 15 is slidably connected to partially or completely detach it from the trough opening, and the flaxseed falls from the discharge trough 13 to the pressing box 17 under the action of gravity and the thrust of the disc 6. The limiting strip 16 fixed at the bottom of the discharge plate 15 is locked onto the outer wall of the stir-frying tank 3, which can limit the sliding stroke of the discharge plate 15 and prevent it from falling completely out of the discharge trough 13, ensuring operational safety. When discharging, the second cylinder 11 on one side of the stir-frying tank 3 is activated, and its piston rod extends and retracts, driving the connecting plate 12 to move horizontally. The connecting rod 14 fixed below the connecting plate 12 moves in sync, thereby pulling or pushing the discharge plate 15 to slide in the discharge trough 13, realizing the automatic opening and closing of the discharge trough 13, replacing manual operation. The output shaft of the servo motor 25 fixed on the outside of the stir-frying tank 3 is rigidly connected to the connecting shaft 4. Through the precise speed control of the motor, the connecting shaft 4 and the L rod 5 are driven to rotate at a set speed, ensuring that the flax seeds are stir-fried evenly and the time is controllable, avoiding over-stirring or under-stirring.
