Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of olive oil pressing, specifically relating to an olive oil kneading and pressing device. Background Technology
[0002] In the process of olive oil production, after the olives are selected and cleaned, they need to be pressed.
[0003] In existing technologies, olive oil is generally extracted using either rotary crushing and pressing or direct pressing, but both methods have shortcomings:
[0004] When pressing olives using a rotary press, insufficient pressing can occur, resulting in a low oil yield. Furthermore, the rapid agitation of the olive oil during the rotary process introduces a large amount of oxygen, causing premature oxidation. Conversely, pressing olives using a direct-pressure method can lead to excessive pressure, causing over-crushing of the pit and pulp, which increases the difficulty of subsequent oil residue separation.
[0005] Therefore, in view of the above-mentioned shortcomings of existing olive oil pressing devices, this utility model discloses an olive oil kneading and pressing device. Utility Model Content
[0006] This utility model discloses an olive kneading and pressing device that can fully knead and press olives, ensuring oil yield while avoiding excessive crushing of olives and preventing the introduction of too much air into the olive oil, which would cause oxidation.
[0007] This utility model is achieved through the following technical solution:
[0008] An olive pressing device includes a pressing cylinder, a rotating frame assembly coaxially rotatably mounted inside the pressing cylinder, and a plurality of pressing components evenly distributed circumferentially around the rotating frame assembly. Each pressing component includes at least one cam portion that rotates relative to the inner wall of the pressing cylinder. A plurality of filter holes are arrayed on the wall of the pressing cylinder. The bottom of the rotating frame assembly is provided with stirring blades that extend into the interior of the pressing cylinder and are staggered with the pressing components.
[0009] The rotating frame assembly rotates clockwise inside the kneading cylinder, causing several kneading components to rotate clockwise as a whole. Each kneading component rotates counterclockwise independently, which in turn causes the cam section to rotate counterclockwise. When the cam section rotates to contact the inner wall of the kneading cylinder, it can knead and crush the olives inside the kneading cylinder. The extracted primary olive oil is filtered through the filter holes on the kneading cylinder wall and discharged to the outside of the kneading cylinder for collection. The remaining pits and pomace after kneading are retained inside the kneading cylinder, achieving separation of oil residue and pits. At the same time, while the kneading components are rotating to knead the olives, the rotating frame assembly drives the stirring blades to rotate, thereby slowly stirring the mixture of oil residue and pits inside the kneading cylinder, so that the kneading components can fully knead the olives and ensure the oil yield.
[0010] To better realize this utility model, the kneading assembly further includes a kneading motor, a kneading shaft, and a kneading cam roller. The kneading shaft is rotatably mounted on the edge of the rotating frame assembly. The top end of the kneading shaft is connected to the output shaft of the kneading motor. A kneading cam roller is sleeved on the outside of the kneading shaft, and at least one cam portion is provided on the outer side of the kneading cam roller.
[0011] To better realize this utility model, furthermore, the outer surface of the kneading cam roller is provided with breaking teeth at a position relative to the cam portion.
[0012] To better realize this utility model, the rotating frame assembly further includes a rotating frame, a rotating frame motor, a rotating frame shaft, and a reduction gear set. The rotating frame shaft is coaxially and rotatably installed inside the kneading cylinder. The rotating frame is sleeved on the rotating frame shaft, and a kneading component is provided at one end of the rotating frame near the cylinder wall. The top end of the rotating frame is connected to the output shaft of the rotating frame motor through the reduction gear set.
[0013] To better realize this utility model, the reduction gear set further includes a first gear, a second gear, a third gear, a planetary gear, and a gear shaft. The first gear and the second gear are respectively sleeved on both ends of the gear shaft, and the gear shaft is rotatably mounted on the rotating frame shaft. The third gear is sleeved on the output shaft of the rotating frame motor and meshes with the first gear. An offset mounting bracket is provided at the top of the rotating frame shaft, and a planetary gear is rotatably mounted on the top of the offset mounting bracket. The planetary gear meshes with the second gear and rotates around the second gear.
[0014] To better realize this utility model, the kneading cylinder is further provided with an outer cylinder, and an oil cavity is formed between the kneading cylinder and the outer cylinder, and at least one set of annular filter screens is provided inside the oil cavity.
[0015] To better realize this utility model, the inner bottom of the kneading cylinder is further provided with a reverse flow cone that is smaller at the top and larger at the bottom.
[0016] To better realize this utility model, the bottom of the kneading cylinder is provided with at least one slag discharge port.
[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0018] This invention uses a rotating frame assembly to drive the kneading and pressing assembly to rotate clockwise, while the kneading and pressing assembly itself rotates counterclockwise, causing its outer cam part to contact the cylinder wall of the kneading and pressing cylinder, thereby realizing the kneading and pressing of olives. This ensures the oil yield while avoiding excessive crushing of the pulp and pit, and also avoids the problem of introducing a large amount of oxygen into the olive oil due to high-speed rotation.

[0028] Example 1:
[0029] This embodiment provides an olive oil kneading and pressing device, such as... Figure 1As shown, the device includes a kneading cylinder 1, a rotating frame assembly 2 is coaxially rotatable inside the kneading cylinder 1, and a plurality of kneading components 3 are evenly distributed around the rotating frame assembly 2 in the circumferential direction. Each kneading component 3 includes at least one cam portion that rotates relative to the inner wall of the kneading cylinder 1. A plurality of filter holes 4 are arrayed on the wall of the kneading cylinder 1. The bottom of the rotating frame assembly 2 is provided with stirring blades 5 that extend into the interior of the kneading cylinder 1 and are staggered with the kneading components 3.
[0030] As shown in the figure, a feed inlet is provided at the top of the kneading cylinder 1, through which olives are added into the kneading cylinder 1. A rotating frame assembly 2 is rotatably mounted at the center of the kneading cylinder 1. The rotating frame assembly 2 includes three sets of support arms evenly distributed around the circumference. Kneading components 3 are mounted on the end of each support arm closest to the cylinder wall of the kneading cylinder 1. The rotating frame assembly 2 rotates clockwise at a speed of less than or equal to 200 rad / min. The kneading components 3 rotate counterclockwise independently at a speed of less than or equal to 350 rad / min. The rotating frame assembly 2 drives all the kneading components 3 to rotate clockwise, simultaneously causing the stirring blades 5 to rotate clockwise, resulting in the olives inside the kneading cylinder 1 being distributed in a clockwise rotation. The kneading component 3 rotates counterclockwise, causing the cam part to synchronously and intermittently squeeze and contact the kneading cylinder 1. When the cam part squeezes and contacts the cylinder wall of the kneading cylinder 1, the olives can be kneaded and pressed. The extracted primary olive oil is discharged to the outside of the kneading cylinder 1 through the filter holes on the cylinder wall of the kneading cylinder 1, while the pomace and pits remain inside the kneading cylinder 1, thus achieving the separation of oil residue and oil pit.
[0031] By using slow kneading and pressing, the problem of insufficient oil-kernel separation caused by crushing the fruit kernels in traditional extrusion pressing is avoided. At the same time, the problems of insufficient oil yield and easy introduction of a large amount of oxygen into the primary olive oil are also avoided by traditional rotary blade cutting oil pressing.
[0032] Example 2:
[0033] This embodiment discloses an olive oil kneading and pressing device, which is an optimization based on Embodiment 1, such as... Figure 3 , Figure 4 As shown, the kneading assembly 3 includes a kneading motor 31, a kneading shaft 32, and a kneading cam roller 33. The kneading shaft 32 is rotatably mounted on the edge of the rotating frame assembly 2. The top end of the kneading shaft 32 is connected to the output shaft of the kneading motor 31. The kneading cam roller 33 is sleeved on the outside of the kneading shaft 32. At least one cam portion is provided on the outer surface of the kneading cam roller 33.
[0034] An isolation plate is provided between the kneading shaft 32 and the kneading motor 31. The kneading shaft 32 is rotatably mounted through a through hole in the isolation plate. The bottom end of the kneading shaft 32 is rotatably connected to the edge of the rotating frame assembly 2. A kneading cam roller 33 extending downward to the bottom of the kneading cylinder 1 is sleeved on the outside of the kneading shaft 32. The top end of the kneading shaft 32 extends above the isolation plate and is connected to the output shaft of the kneading motor 31 via a gear set. The kneading motor 31 drives the kneading shaft 32 to rotate, which in turn drives the kneading cam roller 33 to rotate counterclockwise. The rotation of the kneading cam roller 33 causes the cam part to press against the inner wall of the kneading cylinder 1 to achieve kneading of the olives. At the same time, by setting up the isolation plate, the kneading motor 32 can be isolated from the olives inside the kneading cylinder 1, preventing excessive air from entering the interior of the kneading cylinder 1 and preventing impurities on the kneading motor 32 from falling into the interior of the kneading cylinder 1.
[0035] Furthermore, crushing teeth 34 are provided on the outer surface of the kneading cam roller 33 at a position relative to the cam portion. The kneading cam roller 33 drives the cam portion and the crushing teeth 34 to rotate synchronously. When the cam portion contacts the cylinder wall, the olives are kneaded and pressed. When the crushing teeth 34 correspond to the cylinder wall, the olive pulp is crushed by the crushing teeth 34. It should be noted that there is a gap between the crushing teeth 34 and the cylinder wall of the kneading cylinder 1, and they are not in close contact. The gap is between the diameter of the pit and the diameter of the fruit body, ensuring that the crushing teeth will not crush the pit when crushing the pulp.
[0036] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0038] This embodiment discloses an olive oil kneading and pressing device, which is an optimization based on Embodiment 1 or 2, such as... Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the rotating frame assembly 2 includes a rotating frame 21, a rotating frame motor 22, a rotating frame shaft 23, and a reduction gear set 24. The rotating frame shaft 23 is coaxially and rotatably installed inside the kneading cylinder 1. The rotating frame 21 is sleeved on the rotating frame shaft 23. A kneading component 3 is provided at one end of the rotating frame 21 near the cylinder wall. The top end of the rotating frame 21 is connected to the output shaft of the rotating frame motor 22 through the reduction gear set 24.
[0039] The rotating frame shaft 23 is coaxially rotatably disposed inside the kneading cylinder 1. A rotating frame 21 is sleeved on the outside of the rotating frame shaft 23. The rotating frame 21 includes three sets of circumferentially distributed support arms. A kneading rotating shaft 32 is rotatably mounted at one end of each support arm near the cylinder wall of the kneading cylinder 1. The top end of the kneading rotating shaft 32 is connected to the output shaft of the kneading motor 31. A cover is provided on the top of the kneading cylinder 1. The rotating frame motor 22 is mounted on the top of the cover. The output shaft of the rotating frame motor 22 is connected to the top end of the rotating frame shaft 23 through a reduction gear set 24, thereby driving the rotating frame shaft 23 and the rotating frame 21 to rotate clockwise.
[0040] Furthermore, the reduction gear set 24 includes a first gear 241, a second gear 242, a third gear 243, a planetary gear 244, and a gear shaft. The first gear 241 and the second gear 242 are respectively sleeved on both ends of the gear shaft, and the gear shaft is rotatably mounted on the rotating frame shaft 23. The third gear 243 is sleeved on the output shaft of the rotating frame motor 22, and the third gear 243 meshes with the first gear 241. An offset mounting bracket is provided at the top of the rotating frame shaft 23, and a planetary gear 244 is rotatably mounted on the top of the offset mounting bracket. The planetary gear 244 meshes with the second gear 242 and rotates around the second gear 242.
[0041] One end of the offset mounting bracket is fixedly connected to the top of the rotating frame shaft 23, and the other end of the offset mounting bracket is slidably connected to the annular groove on the inner wall of the top of the kneading cylinder 1 to achieve rotational guidance. The rotating frame motor 22 drives the third gear 243 to rotate, which in turn drives the first gear 241 and the second gear 242 to rotate. Finally, the second gear 242 drives the planetary gear 244 to revolve around the second gear 242, which in turn drives the rotating frame shaft 23 to rotate coaxially inside the kneading cylinder 1.
[0042] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

Figure 4 As shown, an outer cylinder 6 is provided outside the kneading cylinder 1, and an oil cavity is formed between the kneading cylinder 1 and the outer cylinder 6. At least one set of annular filter screens 7 is provided inside the oil cavity. The extra virgin olive oil enters the oil cavity through the filter holes and is filtered by the annular filter screens 7 inside the oil cavity to remove the pomace remaining in the extra virgin olive oil.
[0045] Furthermore, an annular groove is provided at the bottom of the oil cavity, and the bottom of the annular filter 7 is engaged with the annular groove to achieve quick installation of the annular filter 7.
[0046] Furthermore, the inner bottom of the kneading cylinder 1 is provided with a reverse flow cone 8 that is smaller at the top and larger at the bottom. By providing the reverse flow cone 8, the fruit pulp inside the kneading cylinder 1 can flow along the reverse flow cone 8 to the cylinder wall, so that the kneading component 3 can fully knead the fruit pulp and prevent the fruit pulp from accumulating in the center of the kneading cylinder 1.
[0047] Furthermore, the bottom of the kneading cylinder 1 is provided with at least one slag discharge port, and an electrically controlled valve is provided at the slag discharge port.
