Description

Technical Field

[0001] The invention belongs to the technical field of oil pressing devices, and in particular relates to a high-purification camellia seed cold pressing device and a process thereof. Background Art

[0002] Cold pressed oil is a vegetable oil squeezed from oil crops through physical and mechanical action at low temperature (usually below 60°C). This method can retain the nutrients and natural flavor of the oil to the greatest extent while avoiding the adverse effects of high temperature processing. Camellia seeds are generally cold pressed to extract oil.

[0003] At present, when squeezing oil, an oil guide plate is generally set under the oil pressing roller, and the squeezed crude oil is guided to the filter barrel for filtration through the oil guide plate. The crude oil just squeezed generally contains a large amount of foam and impurities. If the crude oil directly passes through the oil guide plate, the foam and impurities in the crude oil will reduce the flow rate of the crude oil, so that the foam may adhere to the surface of the oil guide plate at a slow flow rate. The foam attached to the oil guide plate is easy to breed bacteria. After breeding bacteria, the foam may contaminate the crude oil dripping on the oil guide plate later, thereby reducing the quality of the crude oil. Summary of the invention

[0006] As a preferred embodiment of the above technical solution, the scraper is inclined, and its inclination direction is toward the oil guide plate. The dimensions of the two ends of the scraper become smaller and smaller toward the middle direction. When the scraper moves on the oil guide plate, the crude oil moves toward the middle.

[0007] As a preferred embodiment of the above technical solution, the two opposite plates of the cross flip plate just block the movable cavity in a vertical state, and the cross flip plate freezes after rotating a quarter of a turn counterclockwise.

[0008] As a preferred embodiment of the above technical solution, an extrusion plate is used in conjunction with the sponge block 1, a plurality of telescopic parts are installed in the scraper plate, a movable groove is opened in the scraper plate, a driving block slides in the movable groove, the output end of the telescopic part is connected to the driving block, a plurality of connecting rods are provided on one side of the driving block, the connecting rods extend through the movable cavity, an extrusion plate is rotatably installed on the plurality of connecting rods, an elastic component is provided on the rotating part of the extrusion plate, the extrusion plate always tends to flip downward, and when the driving block moves downward, the extrusion plate squeezes the sponge block 1 while moving downward.

[0009] As a preferred embodiment of the above technical solution, a telescopic groove is provided in the scraper plate, the telescopic groove is connected with the movable cavity, a wedge block is slidably installed in the telescopic groove, a switch button is installed between the wedge block and the telescopic groove, the switch button is connected with a plurality of telescopic parts, the wedge block is used in conjunction with a cross flip plate, and when one of the cross flip plates flips to the telescopic groove, the wedge block is squeezed to retract into the telescopic groove.

[0010] As a preferred embodiment of the above technical solution, a sliding groove is provided at the bottom of the scraper plate, and the scraper plate is slidably installed in the sliding groove. A plurality of elastic parts are arranged between the scraper plate and the sliding groove. A leakage hole is penetrated through the scraper plate, and an oil outlet hole is formed at the bottom of the movable cavity. The oil outlet hole is used in conjunction with the leakage hole. When the scraper plate slides into the sliding groove, the leakage hole coincides with the oil outlet hole.

[0011] As a preferred embodiment of the above technical solution, the cleaning component includes: A fixing rod, wherein the fixing rod is fixed between two protective plates; An elastic plate, the elastic plate is rotatably mounted on the fixed rod, the end of the elastic plate is hook-shaped, the rotating part of the elastic plate is provided with an elastic component, and the elastic plate always tends to be in a state of flipping downward; Sponge block 2: The bottom of the fixing rod is detachably mounted with a sponge block 2.

[0012] As a preferred embodiment of the above technical solution, a guide plate is slidably installed on the top of the oil scraper plate, the guide plate is tilted downward with its tilting direction toward the oil guide plate, and a guide groove is opened through the guide plate.

[0013] A process for a highly purified tea seed cold pressing device, the process is applied to the highly purified tea seed cold pressing device as described above, and the process comprises the following steps: Step S1: The cold pressing equipment presses the tea seeds to produce crude oil, which drips onto the oil guide plate. The driving member is started to rotate the transmission belt, and the rotation of the transmission belt drives the oil scraper plate to move along the oil guide plate. Step S2: When the scraper plate moves, the scraper plate scrapes the crude oil dripping on the oil guide plate, so that the crude oil moves toward the middle of the oil guide plate. At the same time, the contact part between the crude oil and the scraper plate moves the crude oil slowly upward due to the inclination of the scraper plate. The crude oil moving upward contacts the sponge block on the cross flip plate, and the sponge block absorbs the foam in the crude oil. Step S3: When the scraper moves to the cleaning assembly, the scraper slowly moves obliquely upward along the arc portion of the end of the transmission belt, and the elastic plate first presses down the cross flip plate, causing the cross flip plate to rotate a quarter of a turn, so that the sponge block with foam absorption enters the active cavity; Step S4: After the cross flip plate rotates a quarter of a turn, the plate originally against the wedge block slowly moves away from the wedge block, so that the wedge block and the switch button slowly return to their original positions. At this time, the telescopic member drives the extrusion plate to slowly move upward through the driving block and the connecting rod. When the other plate squeezes the wedge block into the telescopic groove, the wedge block presses the switch button, so that the telescopic member drives the extrusion plate to slowly move downward through the driving block and the connecting rod. While the extrusion plate moves downward, it squeezes the sponge block with foam to squeeze out the absorbed crude oil. Step S5: The elastic plate continues to contact the surface of the oil scraper plate, and finally contacts the scraper plate, so that the scraper plate moves into the chute. After the scraper plate moves inward, the leakage hole coincides with the oil outlet hole. At the same time, the crude oil squeezed out of the sponge block drips onto the oil guide plate through the oil outlet hole and the leakage hole. The above steps are cyclically operated until the cold pressing is completed.

[0014] The beneficial effects of the present invention are: 1. In the present invention, the crude oil is scraped by the scraper. When the crude oil is scraped, the contact part between the crude oil and the scraper is slowly accumulated upward because the speed of the scraper is greater than the flow speed of the crude oil. At the same time, the foam in the crude oil is slowly moved upward until it contacts the sponge block. The sponge block absorbs the foam in the crude oil and reduces the foam content in the crude oil, thereby effectively preventing the foam from adhering to the surface of the oil guide plate, preventing the foam adhering to the surface of the oil guide plate from breeding bacteria, and preventing the foam breeding bacteria from contaminating the crude oil dripping on the oil guide plate later; 2. In the present invention, when the scraper scrapes the crude oil downward, the scraper increases the flow speed of the crude oil, thereby reducing the time for the crude oil to flow on the oil guide plate, thereby reducing the residence time of the foam, which can further effectively prevent the foam in the crude oil from adhering to the oil guide plate, and prevent the foam from breeding bacteria and contaminating the crude oil dripping on the oil guide plate later; in addition, the driving member will also vibrate during operation, which can further increase the flow speed of the crude oil, and further effectively prevent the foam in the crude oil from adhering to the oil guide plate; 3. In the present invention, the inclined portion of the scraper can assist the crude oil to accumulate, so that the foam in the crude oil can quickly move up and contact the sponge block, thereby improving the efficiency of eliminating foam. At the same time, the scraper makes the crude oil move closer to the middle, so that the amount of crude oil accumulated on the scraper increases, which can further improve the upward movement speed of the foam in the crude oil, further improve the efficiency of eliminating foam, and further effectively prevent the foam from adhering to the surface of the oil guide plate, prevent the foam adhering to the surface of the oil guide plate from breeding bacteria, and prevent the foam that breeds bacteria from contaminating the crude oil dripping on the oil guide plate later; 4. In the present invention, the foam and a small amount of crude oil absorbed by the sponge block 1 can be squeezed out by the flipping of the cross flip plate and the squeezing of the squeezing plate, and then filtered by the filter plate and dripped onto the oil guide plate through the oil outlet hole and the leakage hole, thus avoiding the waste of crude oil and ensuring the oil output of the oil pressing.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figure 1-Figure 9 As shown, a highly purified tea seed cold pressing device comprises a cold pressing device 1, an oil guide plate 2 and two protective plates 3, the two protective plates 3 form an oil outlet 4, and the device further comprises: The oil scraper 5, both ends of the oil scraper 5 are movably provided with connecting sleeves 51, a transmission belt 31 is installed in the protective plate 3, the other end of the connecting sleeve 51 is fixed to the side of the transmission belt 31, and a driving member 32 is installed on the protective plate 3, and the driving member 32 is connected to the transmission belt 31 in transmission; The scraper 6 is installed on the side of the oil scraper 5 close to the oil outlet 4, and the bottom of the scraper 6 is in contact with the oil guide plate 2; The cross flip plate 7 and the oil scraper plate 5 are provided with an active cavity 53 on one side close to the oil outlet 4. The cross flip plate 7 is rotatably installed in the active cavity 53. The cross flip plate 7 rotates counterclockwise. A plurality of sponge blocks 71 are arranged on the cross flip plate 7. The sponge blocks 71 are located on one side of the rotation direction of the cross flip plate 7. A cleaning component 12 is installed between the two protective plates 3 , and the cleaning component 12 is located between the oil scraper plate 5 and the oil outlet 4 . The cleaning component 12 cleans the crude oil on the oil scraper plate 5 , the scraper plate 6 and the cross flip plate 7 .

[0019] In one case of this embodiment, the driving member 32 may be a motor, or a member capable of driving the transmission belt 31 to rotate; the sponge block 71 may absorb the foam in the crude oil.

[0020] In actual application of this embodiment, the crude oil squeezed out by the cold pressing equipment 1 drips on the oil guide plate 2, and the crude oil flows downward along the oil guide plate 2. The driving member 32 is started to rotate the transmission belt 31, and the transmission belt 31 drives the oil scraper plate 5 to move along the oil guide plate 2. When the oil scraper plate 5 moves along the oil guide plate 2, the scraper plate 6 moves to scrape the crude oil. When the crude oil is scraped, since the moving speed of the scraper plate 6 is greater than the flowing speed of the crude oil, the contact part of the crude oil and the scraper plate 6 slowly accumulates upward, and at the same time, the foam in the crude oil slowly moves upward until it contacts the sponge block 71. The sponge block 71 absorbs the foam in the crude oil and reduces the foam content in the crude oil, thereby effectively preventing the foam from adhering to the surface of the oil guide plate 2, preventing the foam adhering to the surface of the oil guide plate 2 from breeding bacteria, and preventing the foam that breeds bacteria from contaminating the crude oil dripping on the oil guide plate 2 later; When the scraper 6 scrapes the crude oil downward, the scraper 6 increases the flow speed of the crude oil, thereby reducing the time for the crude oil to flow on the oil guide plate 2, thereby reducing the residence time of the foam, which can further effectively prevent the foam in the crude oil from adhering to the oil guide plate 2, and prevent the foam from breeding bacteria and contaminating the crude oil dripping on the oil guide plate 2 later; in addition, the driving member 32 will also vibrate during operation, which can further increase the flow speed of the crude oil, and further effectively prevent the foam in the crude oil from adhering to the oil guide plate 2; The foam in the crude oil is absorbed by the sponge block 71, so that the amount of foam in the crude oil can be reduced. Since the foam contains water vapor, reducing the amount of foam is equivalent to increasing the purity of the crude oil, which provides convenience for the subsequent refining and purification of the crude oil; When the scraper 6 scrapes the crude oil downward, since the crude oil contains impurities, these impurities will also flow downward with the crude oil, which can effectively prevent the impurities in the crude oil from adhering to the oil guide plate 2, thereby preventing the impurities from adhering to the oil guide plate 2 for a long time and hardening, which will make it more troublesome to clean up later, and will also affect the flow rate of the crude oil, and will also block other impurities and foam in the crude oil. In this way, the oil guide plate 2 will be covered with impurities and foam for a long time, which can further effectively prevent the foam in the crude oil from adhering to the oil guide plate 2, and prevent the foam from breeding bacteria and contaminating the crude oil dripping on the oil guide plate 2 later.

[0021] Furthermore, the scraper 6 is inclined, and its inclination direction is toward the oil guide plate 2. The dimensions of both ends of the scraper 6 become smaller and smaller toward the middle direction. When the scraper 6 moves on the oil guide plate 2, the crude oil moves toward the middle.

[0022] In actual application of this embodiment, the inclined portion of the scraper 6 can assist the accumulation of crude oil, so that the foam in the crude oil can quickly move up and contact the sponge block 71, thereby improving the efficiency of eliminating foam. At the same time, the scraper 6 makes the crude oil move closer to the middle, so that the amount of crude oil accumulated on the scraper 6 increases, which can further improve the upward movement speed of the foam in the crude oil, further improve the efficiency of eliminating foam, and further effectively prevent the foam from adhering to the surface of the oil guide plate 2, prevent the foam adhering to the surface of the oil guide plate 2 from breeding bacteria, and prevent the foam that breeds bacteria from contaminating the crude oil dripping on the oil guide plate 2 later.

[0023] Furthermore, the two opposite plates of the cross flip plate 7 just block the movable cavity 53 in the vertical state, and the cross flip plate 7 stops after rotating a quarter of a turn counterclockwise.

[0024] In one case of this embodiment, the rotating part of the cross flip plate 7 is used in conjunction with a ratchet structure, so that the cross flip plate 7 can only rotate counterclockwise and can freeze after rotating a quarter of a turn.

[0025] In actual application of this embodiment, the cross flip plate 7 blocks the active cavity 53, which can effectively prevent crude oil or foam from directly entering the active cavity 53, so as to ensure the amount of crude oil accumulated at the scraper 6 and ensure that a large amount of foam can be absorbed by the sponge block 71; when the scraper plate 5 moves to the cleaning component 12 and is cleaned by the cleaning component 12, the cleaning component 12 touches the cross flip plate 7 to flip the cross flip plate 7, and by flipping the cross flip plate 7, the sponge block 71 for absorbing foam can be replaced, thereby improving the effect of absorbing foam and effectively preventing foam from adhering to the surface of the oil guide plate 2.

[0026] Furthermore, a squeezing plate 8 is used in conjunction with the sponge block 71, a plurality of telescopic members 81 are installed in the scraper plate 5, a movable groove 55 is provided in the scraper plate 5, a driving block 82 slides in the movable groove 55, an output end of the telescopic member 81 is connected to the driving block 82, a plurality of connecting rods 83 are provided on one side of the driving block 82, the connecting rods 83 penetrate into the movable cavity 53, a squeezing plate 8 is rotatably installed on the plurality of connecting rods 83, an elastic component is provided on the rotating part of the squeezing plate 8, the squeezing plate 8 always tends to flip downward, and when the driving block 82 moves downward, the squeezing plate 8 squeezes the sponge block 71 while moving downward.

[0027] In one case of this embodiment, the telescopic member 81 can be a cylinder or a component that can drive the driving block 82 to move up and down; the elastic component of the rotating part of the extrusion plate 8 can be a torsion spring or a component that can make the extrusion plate 8 always tend to flip downward.

[0028] In actual application of this embodiment, since the sponge block 71 absorbs a small amount of crude oil while absorbing foam, at this time, the driving block 82 is moved downward by starting a plurality of telescopic members 81, and then the squeezing plate 8 is driven downward by the connecting rod 83, so that the squeezing plate 8 can squeeze the sponge block 71 below in the vertical state after the flip while moving downward, so as to squeeze out the crude oil absorbed by the sponge block 71, avoid the crude oil from continuing to adhere to the sponge block 71 and reduce the absorption effect of the sponge block 71, and also avoid the waste of crude oil, so as to ensure the oil output of the oil pressing; at the same time, when the squeezing plate 8 moves to the bottom of the cross flip plate 7, since the cross flip plate 7 no longer restricts the squeezing plate 8, the squeezing plate 8 has a downward bounce action, so that the crude oil attached to the squeezing plate 8 is bounced off, effectively avoiding the squeezing plate 8 from being attached to the crude oil, thereby affecting the effect of squeezing the sponge block 71 by the squeezing plate 8 next time to squeeze the crude oil; in addition, the movable chamber 53 is set as a sterile space to avoid the growth of bacteria on the sponge block 71, so as to avoid the crude oil squeezed out of the sponge block 71 containing bacteria.

[0029] Furthermore, a telescopic groove 56 is provided in the oil scraper plate 5, and the telescopic groove 56 is connected to the movable cavity 53. A wedge block 9 is slidably installed in the telescopic groove 56, and a switch button 91 is installed between the wedge block 9 and the telescopic groove 56. The switch button 91 is connected to a plurality of telescopic parts 81. The wedge block 9 is used in conjunction with the cross flip plate 7. When one of the cross flip plates 7 flips to the telescopic groove 56, the wedge block 9 is squeezed to shrink into the telescopic groove 56.

[0030] In one case of the present embodiment, the switch button 91 is a button that can rebound, that is, it shrinks after being pressed once, and can rebound to its original position after being released. The switch button 91 is connected to a plurality of telescopic parts 81. When the switch button 91 is squeezed, the switch button 91 controls the plurality of telescopic parts 81, so that the plurality of telescopic parts 81 are extended to a certain extent and then closed. When the switch button 91 is released from being pressed, the switch button 91 rebounds to its original position. At this time, the switch button 91 controls the plurality of telescopic parts 81, so that the plurality of telescopic parts 81 are contracted to a certain extent and then closed.

[0031] In actual application of this embodiment, when the scraper plate 5 moves to the cleaning component 12 and is cleaned by the cleaning component 12, the cleaning component 12 touches the cross flip plate 7 to flip the cross flip plate 7. After the cross flip plate 7 rotates a quarter of a turn, the plate originally against the wedge block 9 slowly moves away from the wedge block 9, so that the wedge block 9 and the switch button 91 slowly return to their original positions. At this time, the switch button 91 controls the contraction of the plurality of telescopic members 81, and drives the extrusion plate 8 to slowly move upward through the driving block 82 and the connecting rod 83. Before the extrusion plate 8 slowly moves upward, because the plate originally against the wedge block 9 needs to completely leave the wedge block 9 before the telescopic member 81 can be contracted, therefore, another plate on the cross flip plate 7 slowly rotates close to the wedge block. Block 9, at this time, the plate on the cross flip plate 7 slowly approaching the wedge block 9 is already above the squeezing plate 8, and when the squeezing plate 8 moves up, the plate on the cross flip plate 7 slowly approaching the wedge block 9 has been staggered with the squeezing plate 8, so the cross flip plate 7 is not affected by the upward movement of the squeezing plate 8 when it rotates; when the plate on the cross flip plate 7 slowly approaching the wedge block 9 reaches the telescopic groove 56, it will squeeze the wedge block 9 to retract into the telescopic groove 56, thereby pressing the switch button 91, and the switch button 91 will control the extension of the plurality of telescopic members 81, and drive the squeezing plate 8 to slowly move downward through the driving block 82 and the connecting rod 83, and the squeezing plate 8 squeezes the sponge block 71 with foam while moving downward, so that the absorbed crude oil is squeezed out.

[0032] Furthermore, a slide groove 52 is provided at the bottom of the scraper plate 5, and the scraper plate 6 is slidably installed in the slide groove 52. A plurality of elastic members 62 are provided between the scraper plate 6 and the slide groove 52. A leakage hole 61 is provided through the scraper plate 6, and an oil outlet hole 54 is formed at the bottom of the movable cavity 53. The oil outlet hole 54 is used in conjunction with the leakage hole 61. When the scraper plate 6 slides into the slide groove 52, the leakage hole 61 coincides with the oil outlet hole 54.

[0033] In one case of this embodiment, the elastic member 62 may be a spring or a component that can elastically expand and contract.

[0034] In actual application of this embodiment, when the scraper plate 5 moves to the cleaning assembly 12 and is cleaned by the cleaning assembly 12, the cleaning assembly 12 touches the scraper plate 6, so that the scraper plate 6 moves into the chute 52, so that the leakage hole 61 coincides with the oil outlet hole 54. At this time, the crude oil squeezed out from the sponge block 71 by the squeeze plate 8 will drip onto the oil guide plate 2 through the oil outlet hole 54 and the leakage hole 61, thereby avoiding waste of crude oil and ensuring the oil output. At the same time, a filter plate 10 is also installed in the active cavity 53. The filter plate 10 is located between the squeeze plate 8 and the oil outlet hole 54 to filter the squeezed crude oil, effectively preventing the foam from dripping onto the oil guide plate 2 again.

[0035] like Fig.10 As shown, the cleaning component 12 includes: A fixing rod 121, the fixing rod 121 is fixed between the two protection plates 3; The elastic plate 122 is rotatably mounted on the fixed rod 121. The end of the elastic plate 122 is hook-shaped. The rotating part of the elastic plate 122 is provided with an elastic component. The elastic plate 122 always tends to be in a state of flipping downwards. Sponge block 123 123 is detachably mounted on the bottom of the fixing rod 121 .

[0036] In one case of this embodiment, the elastic component of the rotating part of the elastic plate 122 may be a torsion spring, or a component that can make the elastic plate 122 always tend to flip downward.

[0037] In actual application of this embodiment, when the scraper plate 5 moves to the cleaning component 12, the scraper plate 5 slowly moves obliquely upward along the arc-shaped part at the end of the transmission belt 31. During the movement, the elastic plate 122 first presses down the cross flip plate 7 to make the cross flip plate 7 rotate a quarter of a turn. When the cross flip plate 7 rotates to a fixed position, the elastic plate 122 contacts the surface of the scraper plate 5 again, and scrapes off the crude oil on the surface of the scraper plate 5 through the hook at the end of the elastic plate 122, and then contacts the scraper plate 6 to make the scraper plate 6 move into the slide groove 52, and at the same time scrape off the crude oil on the surface of the scraper plate 6; in addition, the sponge block 123 can absorb the foam in the crude oil that continues to flow downward, thereby improving the effect of absorbing the foam, further reducing the foam content in the crude oil, and effectively preventing the foam from adhering to the surface of the oil guide plate 2.

[0038] like Figure 2 , Figure 4 and Figure 5 As shown, a guide plate 11 is slidably mounted on the top of the oil scraper plate 5 . The guide plate 11 is tilted downward, and its tilting direction is toward the oil guide plate 2 . A guide groove 111 is penetrated through the guide plate 11 .

[0039] In actual application of this embodiment, the position of the guide plate 11 is adjusted according to the position where the crude oil drips downward onto the oil guide plate 2, so that the position of the guide plate 11 is located directly below the crude oil dripping. In this way, when the oil scraper plate 5 moves to the position where the crude oil drips downward, the crude oil will drip onto the guide plate 11, and then flow to the oil guide plate 2 through the guide plate 11, so as to avoid the crude oil directly hitting the oil scraper plate 5, thereby affecting the sponge block 71 absorbing foam, and reducing the cleaning work of the oil scraper plate 5 in the later stage; wherein, when the highest point of the guide plate 11 moves to the position directly below the crude oil dripping, a part of the crude oil will drip onto the highest point of the guide plate 11, and at this time, the crude oil will flow to the other side of the guide plate 11, and the flow direction of the crude oil can be changed through the guide groove 111, so as to avoid the crude oil dripping onto the oil scraper plate 5.

[0040] A process for a highly purified tea seed cold pressing device, the process is applied to the highly purified tea seed cold pressing device as described above, and the process comprises the following steps: Step S1: The cold pressing device 1 presses the tea seeds to produce crude oil, which drips onto the oil guide plate 2. The driving member 32 is started to rotate the transmission belt 31, and the rotation of the transmission belt 31 drives the oil scraper plate 5 to move along the oil guide plate 2. Step S2: When the scraper plate 5 moves, the scraper plate 6 scrapes the crude oil dripping on the oil guide plate 2, so that the crude oil moves toward the middle of the oil guide plate 2. At the same time, the part where the crude oil contacts the scraper plate 6 moves slowly upward due to the inclination of the scraper plate 6. The upwardly moving crude oil contacts the sponge block 71 on the cross flip plate 7, and the sponge block 71 absorbs the foam in the crude oil. Step S3: When the scraper plate 5 moves to the cleaning assembly 12, the scraper plate 5 slowly moves obliquely upward along the arc portion of the end of the transmission belt 31, and the elastic plate 122 first presses down the cross flip plate 7, so that the cross flip plate 7 rotates a quarter of a turn, so that the sponge block 71 with foam absorption enters the active cavity 53; Step S4: After the cross flip plate 7 rotates a quarter of a turn, the plate originally against the wedge block 9 slowly moves away from the wedge block 9, so that the wedge block 9 and the switch button 91 slowly return to their original positions. At this time, the telescopic member 81 drives the squeezing plate 8 to slowly move upward through the driving block 82 and the connecting rod 83. When another plate squeezes the wedge block 9 to retract into the telescopic groove 56, the wedge block 9 presses the switch button 91, so that the telescopic member 81 drives the squeezing plate 8 to slowly move downward through the driving block 82 and the connecting rod 83. While moving downward, the squeezing plate 8 squeezes the sponge block 71 that absorbs foam, so that the absorbed crude oil is squeezed out. Step S5: the elastic plate 122 continues to contact with the surface of the oil scraper plate 5, and finally contacts with the scraper plate 6, so that the scraper plate 6 moves into the chute 52. After the scraper plate 6 moves inward, the leakage hole 61 coincides with the oil outlet hole 54. At the same time, the crude oil squeezed out of the sponge block 71 drips onto the oil guide plate 2 through the oil outlet hole 54 and the leakage hole 61. The above steps are cyclically operated until the cold pressing is completed.

9. A process for a highly purified tea seed cold pressing device, characterized in that: The process is applied to the highly purified tea seed cold pressing device as described in any one of claims 1 to 8 above, and the process comprises the following steps: Step S1: The cold pressing device (1) presses the tea seeds to produce crude oil, which drips onto the oil guide plate (2). The driving member (32) is started to rotate the transmission belt (31), and the rotation of the transmission belt (31) drives the oil scraper plate (5) to move along the oil guide plate (2); Step S2: When the scraper plate (5) moves, the scraper plate (6) scrapes the crude oil dripping on the oil guide plate (2), so that the crude oil moves toward the middle of the oil guide plate (2). At the same time, the part where the crude oil contacts the scraper plate (6) slowly moves upwards due to the inclination of the scraper plate (6). The upwardly moving crude oil contacts the sponge block 1 (71) on the cross flip plate (7), and the sponge block 1 (71) absorbs the foam in the crude oil. Step S3: When the oil scraper (5) moves to the cleaning assembly (12), the oil scraper (5) slowly moves obliquely upward along the arc portion of the end of the transmission belt (31), and the elastic plate (122) first presses the cross flip plate (7) downward, causing the cross flip plate (7) to rotate a quarter of a turn, so that the sponge block (71) containing the foam absorbent enters the active chamber (53); Step S4: After the cross-turning plate (7) rotates a quarter of a turn, the plate originally against the wedge block (9) slowly moves away from the wedge block (9), so that the wedge block (9) and the switch button (91) slowly return to their original positions. At this time, the telescopic member (81) drives the squeezing plate (8) to slowly move upwards through the driving block (82) and the connecting rod (83). When the other plate squeezes the wedge block (9) and retracts into the telescopic groove (56), the wedge block (9) presses the switch button (91), so that the telescopic member (81) drives the squeezing plate (8) to slowly move downwards through the driving block (82) and the connecting rod (83). While the squeezing plate (8) moves downwards, it squeezes the sponge block (71) that absorbs foam, so that the absorbed crude oil is squeezed out. Step S5: the elastic plate (122) continues to contact the surface of the oil scraper plate (5), and finally contacts the scraper plate (6), so that the scraper plate (6) moves into the chute (52). After the scraper plate (6) moves inward, the leak hole (61) coincides with the oil outlet hole (54). At the same time, the crude oil squeezed out of the sponge block (71) drips onto the oil guide plate (2) through the oil outlet hole (54) and the leak hole (61). The above steps are cyclically operated until the cold pressing is completed.
