Description

A coffee fruit peel extract filtration device Technical Field

[0001] This invention relates to the field of fruit peel extract filtration technology, and more specifically, to a coffee fruit peel extract filtration device. Background Technology

[0002] In actual production scenarios, coffee husks, after a series of processing steps, form a solid-liquid mixture of extracts. For convenient subsequent use, this mixture needs to be separated. Traditional filtration equipment typically uses filters with fixed pore sizes, which are ill-suited to the complex components and diverse particle sizes in coffee husk extracts. The unique structure of coffee husks, containing fibers, pectin, and other substances, easily clogs the filters during filtration. For example, in some conventional plate and frame filtration systems, the filters quickly become clogged with coffee husk debris and sticky substances when processing coffee husk extracts, leading to a significant decrease in filtration speed. This necessitates frequent shutdowns for filter cleaning, severely impacting production efficiency and increasing production costs.

[0003] In addition, although some existing filtration devices have the function of adjusting the size of the filter port, the size of the filter port is fixed after adjustment. During the filtration process, as the coffee fruit peel solid-liquid mixture is continuously consumed and the filtration situation changes, it is impossible to adjust the filtration parameters in real time to ensure the best filtration effect. This leads to the filter port becoming clogged in the later stage of filtration, and the filtration efficiency is difficult to guarantee. Therefore, we have designed a coffee fruit peel extract filtration device. Summary of the Invention

[0005] This invention provides a coffee fruit peel extract filtration device, comprising an extension component and a frame deformation component forming a rectangular structure.

[0008] As a further optimization of the present invention, a plurality of feed pipes are fixedly mounted on the first rotating plate at an angle, and a one-way valve is installed on the feed pipes.

[0009] As a further optimization of the present invention, the frame-changing assembly further includes a partition plate fixedly installed in the groove of the second rotating plate; a sliding plate slidably installed inside the groove and connected to the second rotating plate by a third spring; and a shielding cloth, one end of which is fixedly connected to the shielding plate and the other end of which is fixedly connected to the sliding plate, and the shielding cloth is slidably connected to the sliding box.

[0010] As a further optimization of the present invention, the extension mechanism includes a first hollow seat rotatably connected to the hollow rotating tube, and two first hollow seats are respectively fixedly connected to a second rotating plate and a first rotating plate; an adjustment component is installed on the second rotating plate to control the included angle between adjacent rotating boxes.

[0011] As a further optimization of the present invention, the driving mechanism includes a working box, wherein the extension component and the frame deformation component constituting the rectangular structure are both located inside the working box; a motor, fixedly mounted on the working box, on which a drive shaft is fixedly mounted and connected to a second rotating plate through the drive shaft; a second gear, fixedly mounted on the working box; a reciprocating lead screw, rotatably mounted on the second rotating plate, on which a threaded block is threadedly connected, the threaded block being fixedly connected to an adjusting component; and a first gear, fixedly mounted on the reciprocating lead screw and meshing with the second gear.

[0012] As a further optimization of the present invention, the gas supply mechanism includes a mounting box fixedly connected to the working box; a wedge block slidably installed inside the mounting box and connected to the mounting box via a first spring; a guide pipe fixedly installed on the mounting box, on which a one-way valve is installed, with its two ends located on the upper and lower sides of the wedge block respectively; a gas delivery box fixedly installed on the first rotating plate, on which a squeezing pipe is rotatably installed, the squeezing pipe being connected to the guide pipe; and a first gas delivery pipe fixedly installed on the first rotating plate, one end of which is connected to the first gas delivery pipe and the other end of which is connected to the first hollow seat.

[0013] As a further optimization of the present invention, a filter plate is slidably installed inside the working box, and a rotating seat is slidably connected inside the working box, the rotating seat being rotatably connected to the first rotating plate.

[0014] As a further optimization of the present invention, the adjusting assembly includes an extension box fixedly connected to a threaded block; an extension column slidably mounted on the extension box, on which a common screw is threadedly connected, the common screw being rotatably connected to the extension box; a first bevel gear fixedly mounted on the common screw; an adjusting column rotatably mounted on the adjusting column, with a second bevel gear meshing with the first bevel gear fixedly mounted at its top end; the extension assembly also includes a push plate rotatably connected to a hollow rotating tube; a first slide rod slidably mounted on the second rotating plate and fixedly connected to the push plate; and a fourth spring sleeved on the first slide rod, with its two ends respectively connected to the push plate and the second rotating plate.

[0015] The beneficial effects of this invention are as follows: 1. The coffee husk extract filtration device of this invention has rotating boxes arranged in a cross pattern and connected by hollow rotating tubes. The cutter fixed on the rotating box can cut the coffee husk under the action of the adjusting component, preventing it from clogging the filter port. When the motor drives the second rotating plate to rotate, it causes the extension component to deform, making the coffee husk solid-liquid mixture continuously turn over, promoting solid-liquid separation. At the same time, the wedge block, extrusion tube and other parts of the gas supply mechanism work synchronously to deliver gas to the one-way nozzle. The sprayed gas can impact the coffee husk covering the surface of the filter port, causing it to fall off, ensuring a smooth filtration process, greatly improving filtration efficiency, reducing downtime caused by clogging, and reducing production costs.

[0016] 2. The coffee fruit peel extract filtration device of the present invention, when it is necessary to filter solid substances, drives the second conical gear to rotate by rotating the adjusting column, thereby causing the first conical gear meshing with the second conical gear to rotate, driving the ordinary screw to rotate, causing the extension column to move, changing the overall length of the extension box and the extension column, thereby adjusting the degree of deformation of the rotating box and changing the size of the diamond-shaped filter port; through this adjustment function, the filtration needs of solid substances of different particle sizes can be met, realizing graded filtration, improving the accuracy and adaptability of filtration, and ensuring the stability of the quality of the final extract.

[0017] 3. In the coffee fruit peel extract filtration device of the present invention, during the filtration process, the liquid discharged from the rectangular structure will undergo secondary filtration through the filter plate; the filter plate can intercept the cut coffee fruit peel and other impurities, preventing them from mixing into the liquid; in addition, the baffle plate, baffle cloth and other parts in the frame deformation assembly can prevent coffee fruit peel residue, ensuring that only liquid is discharged through the filter port; furthermore, the stirring rod will move with the continuous deformation of the extension assembly, which can stir the filtered material and prevent it from piling up and affecting filtration.

Detailed Implementation

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0031] As shown in Figures 1 to 11, the coffee fruit peel extract filtration device according to an embodiment of the present invention includes an extension component and a frame deformation component forming a rectangular structure. The extension component includes multiple intersecting rotating boxes 418; a hollow rotating tube 431 passes through the rotating boxes 418 and is rotatably connected to the rotating boxes 418, and has a through hole; a cutter 427 is fixedly installed on the rotating boxes 418, and a cutting edge is formed between two adjacent cutters 427; a connecting box 426 is fixedly installed on the rotating boxes 418 and communicates with the hollow rotating tube 431; a top block 425 is fixedly installed on the rotating boxes 418, and a second air supply pipe 430 communicating with the connecting box 426 is provided between the multiple top blocks 425, and multiple one-way nozzles 429 are fixedly installed on the second air supply pipe 430; an air supply mechanism provides airflow between the multiple top blocks 425 during the deformation of the extension component; and a drive mechanism moves the coffee fruit peel during the process of filtering coffee fruit peel extract in the rectangular structure, causing the coffee fruit peel to rotate and shake synchronously with the rectangular structure.

[0032] It should be noted that during coffee extraction, some liquid needs to be placed inside, resulting in a solid-liquid mixture of coffee fruit peels. Since the extension component and the frame-changing component form a rectangular structure, and this rectangular structure is equipped with a feed inlet, the solid-liquid mixture of coffee fruit peels can be placed inside the rectangular structure. The extension component on the rectangular structure will form multiple variable rhomboid structures, and the opening size of the rhomboid structure is the size of the filter port, which can intercept the coffee fruit peels. The liquid extract will be discharged from the filter port, thereby effectively achieving solid-liquid separation filtration.

[0033] When the solid-liquid mixture of coffee fruit peels is placed into the rectangular structure, it is rotated by a drive mechanism. This causes the solid-liquid mixture to tumble inside the rectangular structure, promoting solid-liquid separation. During the tumbling process, a variable rhomboid structure continuously changes from its largest opening to a closed state. This not only moves the solid-liquid mixture of coffee fruit peels but also squeezes and deforms the coffee peels within the variable rhomboid structure, preventing them from getting stuck and allowing them to be expelled. The variable rhomboid structure also forms a cutting edge, which can cut the coffee peels, directly solving the problem of coffee peels getting stuck.

[0034] The top block 425, in conjunction with the second air supply pipe 430, can clean the coffee husks attached to the variable rhombus structure during its continuous movement, preventing the coffee husks inside the rectangular structure from clogging the variable rhombus structure and accelerating its filtration.

[0035] As shown in Figure 4, the frame variable component includes two sliding boxes 403, with a baffle plate 416 slidably connected inside. The sliding boxes 403 are slidably connected to a second rotating plate 405 with a built-in groove through a connecting component, and the baffle plate 416 is slidably connected to a first rotating plate 401 through a connecting component.

[0036] When the drive mechanism drives the extension component to deform, since the baffle plate 416 is slidably connected to the first rotating plate 401 and the second rotating plate 405, it can deform accordingly and until it fits tightly to form a rectangle.

[0037] The connecting assembly includes a fixing plate 420, which is fixedly connected to the first rotating plate 401 near the first rotating plate 401 and fixedly connected to the second rotating plate 405 near the second rotating plate 405; a plurality of second sliding rods 419 are slidably mounted on the fixing plate 420 and fixedly connected to the baffle plate 416 and the sliding box 403 respectively; a second spring 415 is sleeved on the second sliding rods 419, with the two ends of the second spring 415 located at the baffle plate 416 connected to the baffle plate 416 and the fixing plate 420 respectively, and the two ends of the second spring 415 located at the sliding box 403 connected to the sliding box 403 and the fixing plate 420 respectively.

[0038] Due to the setting of the second spring 415, a radial force pointing towards the center can be given to the baffle plate 416 and the sliding box 403, so that no matter how it changes, the baffle plate 416 and the sliding box 403 can fit with the extension component to form a rectangular structure for filtering the solid-liquid mixture of coffee peel.

[0039] Multiple feed pipes 411 are fixedly installed at an angle on the first rotating plate 401, and one-way valves are installed on the feed pipes 411. This setting allows the solid-liquid mixture of coffee husks to enter but not exit, thus preventing some coffee husks from being discharged from the feed pipes 411 during the filtration process of the rectangular structure.

[0040] As shown in Figure 11, the frame transformer assembly also includes a partition 428 fixedly installed in the groove of the second rotating plate 405; a slide plate 404 is slidably installed inside the groove and connected to the second rotating plate 405 by a third spring 423; one end of the shielding cloth 417 is fixedly connected to the shielding plate 416, the other end is fixedly connected to the slide plate 404, and the shielding cloth 417 is slidably connected to the sliding box 403.

[0041] When the shield 416 and the sliding box 403 are deformed by the extension component and extend or retract, the shielding cloth 417 will cover the part of the sliding box 403 that is not covered by the shield 416 to prevent gaps from causing coffee peel residue. When the shield 416 and the sliding box 403 return to their original state and merge, they will be retracted under the action of the third spring 423 to facilitate subsequent operation.

[0042] As shown in Figures 4, 7, and 9, the extension assembly includes a first hollow seat 414 rotatably connected to the hollow rotating tube 431, and two first hollow seats 414 are fixedly connected to the second rotating plate 405 and the first rotating plate 401, respectively; the adjustment assembly is installed on the second rotating plate 405 to control the included angle between adjacent rotating boxes 418.

[0043] Please refer to Figures 3 and 4. The drive mechanism includes a working box 1, and the extension component and the frame deformation component that form a rectangular structure are both located inside the working box 1. The motor 2 is fixedly installed on the working box 1, and a drive shaft 410 is fixedly installed on it and connected to the second rotating plate 405 through the drive shaft 410. The second gear 409 is fixedly installed on the working box 1. The reciprocating screw 406 is rotatably installed on the second rotating plate 405, and a threaded block 421 is threadedly connected to it. The threaded block 421 is fixedly connected to the adjustment component. The first gear 408 is fixedly installed on the reciprocating screw 406 and meshes with the second gear 409.

[0044] When the solid-liquid mixture of coffee cherries is fed into the rectangular structure through the feed pipe 411, the motor 2 is started. The motor 2 drives the second rotating plate 405 to rotate through the drive shaft 410. The second rotating plate 405 drives the first rotating plate 401 to rotate through the extension assembly composed of multiple rotating boxes 418, the baffle plate 416, and the sliding box 403. In this way, the rectangular structure will continuously flip, so that the solid-liquid mixture of coffee cherries will continuously flip inside. During the flipping process, the liquid and solid in the solid-liquid mixture of coffee cherries will separate. The liquid will be discharged through the diamond-shaped filter port formed by the extension assembly, while the solid will be intercepted inside.

[0045] When the second rotating plate 405 rotates, the reciprocating screw 406 on it also rotates. Since the reciprocating screw 406 meshes with the second gear 409, it rotates around the drive shaft 410 while also rotating on its own axis, causing the reciprocating screw 406 to rotate as well. This causes the threaded block 421 to drive the adjusting component to move back and forth. The adjusting component drives the rotating box 418, which can form an extension component by multiple rotating boxes 418, opening or closing. This changes the shape of the diamond-shaped filter opening formed by the rotating boxes 418, thereby squeezing and deforming the coffee husks stuck in the diamond-shaped filter opening. During the flipping process, they will fall off, preventing the diamond-shaped filter opening from becoming blocked. Furthermore, the change in the rotating box 418 can also move the solid-liquid mixture of coffee husks, preventing the solid-liquid mixture of coffee husks from piling up.

[0046] Since the rotating box 418 is fixedly equipped with cutters 427, the multiple cutters 427 form a scissor-like structure. When the coffee husks fall in, they can be directly cut off during the reciprocating movement of the adjusting component to deform them, thereby further preventing the diamond-shaped filter from clogging.

[0047] As shown in Figures 2, 5, and 8, the gas supply mechanism includes a mounting box 301 fixedly connected to the working box 1; a wedge block 304 slidably installed inside the mounting box 301 and connected to the mounting box 301 via a first spring 302; a guide pipe 303 fixedly installed on the mounting box 301, on which a one-way valve is installed, with its two ends located on the upper and lower sides of the wedge block 304 respectively; a gas delivery box 412 fixedly installed on the first rotating plate 401, on which a squeezing pipe 305 is rotatably installed, and the squeezing pipe 305 is connected to the guide pipe 303; and a first gas delivery pipe 413 fixedly installed on the first rotating plate 401, with one end connected to the first gas delivery pipe 413 and the other end connected to the first hollow seat 414.

[0048] As the motor 2 drives the extension assembly to continuously change, the distance between the first rotating plate 401 and the second rotating plate 405 continuously changes. This causes the extrusion tube 305 to move left and right continuously. The left and right movement of the extrusion tube 305 causes the wedge block 304 to be squeezed or released, thereby causing the wedge block 304 to move up and down continuously. The up and down movement of the wedge block 304 delivers the gas in the space formed by the extrusion tube 305 and the mounting box 301 to the guide tube 303, and then from the guide tube 303 to the extrusion tube 305. Subsequently, the gas enters the first hollow seat 414 through the gas delivery box 412 and the first gas delivery pipe 413. The gas entering the first hollow seat 414 is delivered to multiple rotating boxes 418 through the hollow rotating pipe 431. After multiple rotating boxes 418 are filled with gas, more gas is poured into the rotating boxes 418. When gas is being supplied, it enters the one-way nozzle 429 through the adapter box 426 and the second gas supply pipe 430, and exits from the one-way nozzle 429. The mounting box 301 is equipped with a one-way air inlet pipe, so the gas can only be continuously supplied to the rotating box 418 and finally exit from the one-way nozzle 429. In this case, when the coffee husk is not stuck in the diamond-shaped filter opening, but covers the surface of the diamond-shaped filter opening, it will also affect the filtration of the filter opening. Therefore, the setting of the top block 425 can reduce the contact area between the coffee husk and the filter opening, reducing the adhesion of the coffee husk. During the movement of the rotating box 418, it will rotate continuously, and the force generated will also cause the coffee husk to fall off. Finally, the gas ejected from the one-way nozzle 429 can further impact the coffee husk, causing the coffee husk to fall off and preventing the coffee husk from affecting the filtration of the filter opening.

[0049] As shown in Figure 2, a filter plate 5 is slidably installed inside the working box 1, and a rotating seat 402 is slidably connected inside the working box 1. The rotating seat 402 is rotatably connected to the first rotating plate 401.

[0050] The liquid discharged from the rectangular structure passes through filter plate 5 and is further filtered by filter plate 5 to improve the filtration accuracy. Because filter plate 5 is slidable, it can be slidably removed to facilitate the cleaning of some impurities from secondary filtration. In addition, the operation of cutting coffee husks using a scissor-like structure can intercept the cut coffee husks and prevent them from mixing into the liquid.

[0051] As shown in Figure 10, the adjustment assembly includes an extension box 422 fixedly connected to a threaded block 421; an extension column 434 slidably mounted on the extension box 422, on which a common screw 433 is threadedly connected, and the common screw 433 is rotatably connected to the extension box 422; a first bevel gear 432 is fixedly mounted on the common screw 433; and an adjustment column 436 is rotatably mounted on the adjustment column 436, with a second bevel gear 435 fixedly mounted at its top end, meshing with the first bevel gear 432.

[0052] The extension assembly also includes a push plate 437 rotatably connected to the hollow rotating tube 431; a first slide rod 407 is slidably mounted on the second rotating plate 405 and fixedly connected to the push plate 437; a fourth spring 438 is sleeved on the first slide rod 407 and its two ends are respectively connected to the push plate 437 and the second rotating plate 405.

[0053] When motor 2 starts, it causes the first gear 408 to move on the second gear 409. This first gear 408 drives the reciprocating screw 406 to rotate. The rotation of the reciprocating screw 406 causes the threaded block 421 to move back and forth. The reciprocating movement of the threaded block 421 causes the extension box 422 and the extension column 434 to move back and forth, thus squeezing the push plate 437 and causing multiple rotating boxes 418 to unfold. When the second slide rod 419 squeezes, it retracts under the action of the fixed plate 420, forming a dynamic adjustment for filtering the solid-liquid mixture of coffee cherries. After the liquid in the coffee cherries' solid-liquid mixture is filtered out, it may be necessary to filter the solids, such as by size. This can be achieved through... By rotating the adjusting column 436, the ordinary screw 433 can be rotated through the second bevel gear 435 and the first bevel gear 432. Subsequently, the extension column 434 moves, thus changing the overall length of the extension box 422 and the extension column 434. As a result, when the second slide rod 419 is squeezed, the distance that the second slide rod 419 moves becomes different. Consequently, the deformation degree of the multiple rotating boxes 418 will also be different, which can change the size of the diamond-shaped filter port and achieve continuous filtration of solid materials. This filtration process is used in conjunction with the function of preventing the filter port from being blocked. Finally, the solid materials filtered in stages will fall onto the filter plate 5 for easy removal.

[0054] As shown in Figure 8, a stirring rod 424 is fixedly installed on the adapter box 426. The stirring rod 424 is branch-shaped.

[0055] As the multiple rotating boxes 418 continuously rotate and change the size of the diamond-shaped filter opening, the stirring rod 424 will continuously change during its movement. Its branches will stir the solid-liquid mixture of coffee fruit peels to prevent them from piling up. Furthermore, the expansion and contraction of the multiple rotating boxes 418 will also shake the solid-liquid mixture of coffee fruit peels to prevent them from piling up, which would be detrimental to filtration.

[0056] Working principle: The coffee fruit peel solid-liquid mixture is fed into the rectangular structure composed of the extension component and the frame deformation component through the feed pipe 411; the one-way valve on the feed pipe 411 ensures that the mixture can only enter and not exit.

[0057] Motor 2 drives the second rotating plate 405 to rotate via drive shaft 410. The second rotating plate 405 drives the extension assembly, baffle plate 416, sliding box 403 and first rotating plate 401, which are composed of rotating box 418, etc., to rotate. The rectangular structure continuously flips, causing the liquid and solid inside the mixture to separate. The liquid is discharged through the diamond-shaped filter port formed by the extension assembly.

[0058] When the second rotating plate 405 rotates, the reciprocating lead screw 406 on it rotates accordingly; the reciprocating lead screw 406 meshes with the second tooth 409, rotates around the drive shaft 410 and rotates on its own axis, driving the threaded block 421 to move; the threaded block 421 drives the adjusting component to open or close the extension component, changing the shape of the diamond-shaped filter opening; the cutter 427 is fixed on the rotating box 418. When the coffee husks fall in, during the process of the adjusting component deforming them, the cutter 427 cuts the coffee husks to prevent the diamond-shaped filter opening from clogging. At the same time, the change in the rotating box 418 can also agitate the mixture to avoid accumulation.

[0059] Motor 2 drives the extension assembly to change, altering the distance between the first rotating plate 401 and the second rotating plate 405. The extrusion tube 305 moves left and right to extrude or release the wedge block 304. The wedge block 304 moves up and down within the mounting box 301, delivering gas through the guide tube 303, extrusion tube 305, gas delivery box 412, first gas delivery pipe 413, first hollow seat 414, and hollow rotating tube 431 to the rotating box 418. The gas is then discharged from the one-way nozzle 429 through the adapter box 426 and the second gas delivery pipe 430. The top block 425 reduces the adhesion of the coffee peel, and the force generated by the rotation of the rotating box 418 causes the coffee peel to fall off. The gas sprayed from the one-way nozzle 429 further impacts the filter, causing the coffee peel covering the filter surface to fall off, thus avoiding affecting the filtration.

[0060] The liquid discharged from the rectangular structure is filtered a second time through filter plate 5 to improve the filtration accuracy. Filter plate 5 can be slidably removed to facilitate the cleaning of impurities from the second filtration, while also intercepting the cut coffee husks to prevent them from mixing into the liquid.

[0061] When it is necessary to filter solid objects by size, rotate the adjusting column 436, which drives the ordinary screw 433 to rotate through the second bevel gear 435 and the first bevel gear 432, causing the extension column 434 to move, changing the overall length of the extension box 422 and the extension column 434, thereby changing the degree of deformation of the rotating box 418 and the size of the diamond-shaped filter port, so as to realize the graded filtration of solid materials. The graded filtered solid materials fall onto the filter plate 5 for easy removal.

[0062] As the rotating box 418 rotates and changes the size of the diamond-shaped filter opening, the branch-shaped stirring rod 424 on the transfer box 426 stirs the coffee pulp solid-liquid mixture. At the same time, the expansion and contraction of the rotating box 418 also shakes the mixture, preventing it from piling up and facilitating filtration.

[0063] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
