Description

Technical Field

[0001] This invention relates to the field of coffee extraction equipment technology, specifically to a high-efficiency coffee extraction device. Background Technology

[0002] Coffee liquid is a liquid obtained by extracting coffee powder. It has a rich coffee flavor and aroma and is an important raw material for making various coffee drinks. The extraction of coffee liquid is a process of dissolving and extracting soluble substances from coffee powder using hot water. When hot water comes into contact with coffee powder, water molecules penetrate into the coffee powder particles, dissolving the soluble substances. Then, through diffusion, these substances are carried out of the coffee powder particles to form coffee liquid.

[0003] In industrial production, the espresso method is commonly used. Espresso is a method that uses high pressure to force hot water through a coffee puck to extract concentrated coffee in a short time. In order to improve the extraction efficiency, a large amount of coffee grounds are filled into the container. Because the high-pressure hot water flows from one end of the puck to the other, the water temperature near the water outlet is higher and the extraction efficiency is faster. As the water flows, its temperature gradually decreases and its saturation increases, resulting in the water flowing to the end of the puck being colder and more saturated. This makes the extraction effect of the coffee puck at the end poorer, which can easily lead to over-extraction at the front of the puck and incomplete extraction at the back.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a highly efficient coffee extraction device, which has the following beneficial effects: 1. By setting up an extraction cylinder, which rotates inside the extraction tank and is in a horizontal position during extraction, the coffee powder is filled and compacted inside the outer filter of the extraction cylinder. When extraction is in progress, hot water flows into the inner filter through the water supply pipe and the outlet. At this time, due to gravity, the hot water flows downward and passes through the inner filter and coffee powder, then extracts the coffee liquid and flows into the extraction tank through the outer filter. During this period, the extraction cylinder only needs to rotate to ensure that all the coffee powder inside can be extracted. The hot water flows only the radius of the outer filter cartridge, which significantly shortens the flow distance and avoids the problems of temperature drop and oversaturation caused by excessively long flow paths. In addition, the diameter of the water outlet gradually decreases from the inlet to the outlet, which ensures that the flow rate of each outlet is consistent and that the extraction efficiency is synchronized. The inner filter cartridge is designed to surround the water supply tube, which prevents the water from directly hitting the coffee grounds without affecting the heat flow and avoids impacting the extraction effect.

[0016] 2. By setting up a driving component, which mainly consists of toothed rings on the extraction cylinder, and idler wheels meshing between adjacent toothed rings, the reduction motor used for driving only needs to mesh with the toothed rings on one side. Then, by using the transmission of the idler wheels, all extraction cylinders can rotate synchronously, ensuring consistent extraction work and results, and achieving the goal of efficient extraction.

[0017] 3. By setting up a water supply component, the water supply component mainly consists of a main water supply pipe that connects to the external water supply equipment. It has multiple branch water supply pipes on its side that connect to the inner water supply pipe, so that hot water can be distributed to the inner water supply pipe through the branch water supply pipes. The branch water supply pipes are equipped with constant pressure valves, which can automatically adjust according to the water pressure to make the water pressure of all branch water supply pipes consistent, avoiding the problem of different water supply due to the location of the branch water supply pipes. At the same time, the rotary joint inside the branch water supply pipe can connect with the inner water supply pipe in the rotating state to ensure the stability of water flow.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-12A high-efficiency coffee extraction device includes a support frame 1, an extraction tank 2 rotatably disposed inside the support frame 1, a drive motor 3 for driving the extraction tank 2 to rotate horizontally on the outside of the support frame 1, a coffee liquid outlet 14 at the bottom of the extraction tank 2, and multiple extraction cylinders 4 rotatably disposed inside the extraction tank 2. Each extraction cylinder 4 includes an outer filter cylinder 401 that passes through both ends of the extraction tank 2 and is rotatably connected thereto. One end of the outer filter cylinder 401 is closed and the other end is open, and wing plates 405 are provided near both ends. An inner filter cylinder 402 is provided at the center of the outer filter cylinder 401. A water supply inner pipe 403 is provided in the inner filter cylinder 402. A water outlet 404 is provided below the water supply inner pipe 403, and the diameter of the water outlet 404 gradually decreases from the water inlet end to the end end. like Figure 1 , Figure 4 , Figure 5 As shown, by setting up an extraction cylinder 4, the extraction cylinder 4 is rotated inside the extraction tank 2 and is in a horizontal state during extraction. The coffee powder is filled and compacted inside the outer filter cylinder 401 of the extraction cylinder 4. When the extraction is performed, hot water flows into the inner filter cylinder 402 through the water supply pipe 403 and the water outlet 404. At this time, due to gravity, the hot water flows downward and passes through the inner filter cylinder 402 and the coffee powder, and then extracts the coffee liquid and flows into the extraction tank 2 through the outer filter cylinder 401. During this period, the extraction cylinder 4 only needs to rotate to ensure that all the coffee powder inside can be extracted. The hot water flows only a distance equal to the radius of the outer filter cartridge 401, which can significantly shorten the flow distance of the hot water and avoid the problem of temperature drop and oversaturation caused by the hot water flowing too far. In addition, the diameter of the outlet 404 gradually decreases from the inlet end to the outlet end. This method can ensure that the delivery flow of each outlet 404 is consistent and ensure that the extraction efficiency is synchronized. The inner filter cartridge 402 uses the setting of surrounding the water supply inner pipe 403 to avoid the water flow directly hitting the coffee powder without affecting the heat flow, and to prevent the impact channel from affecting the extraction effect. Furthermore, it should be noted that wing plates 405 are provided at both ends of the outer filter cartridge 401. The wing plates 405 are located inside the extraction tank 2. During extraction, the wing plates 405 will block the coffee liquid and make it flow downwards, preventing the coffee liquid from flowing along the outer filter cartridge 401 to the end face, preventing the coffee liquid from contacting the connecting parts of the extraction cartridge 4 and the extraction tank 2, and reducing the pressure on the rotational sealing performance.

[0022] One end of the extraction tank 2 is provided with a drive component 6 that drives the extraction cylinder 4 to rotate. The drive component 6 includes a toothed ring 601 located on the outside of the extraction cylinder 4. The extraction tank 2 is provided with a reduction motor 603 that meshes with the toothed ring 601. The end face of the extraction tank 2 is provided with an idler wheel 602 that meshes with the adjacent toothed ring 601. like Figure 6 and Figure 7As shown, by setting up a driving component 6, the driving component 6 is mainly composed of a toothed ring 601 set on the extraction cylinder 4, and an idler wheel 602 meshes between adjacent toothed rings 601. The reduction motor 603 used for driving only needs to mesh with the toothed ring 601 on one side. Then, by using the transmission of the idler wheel 602, all extraction cylinders 4 can rotate synchronously, ensuring consistent extraction work and effect, and achieving the purpose of efficient extraction.

[0023] The end face of the extraction tank 2 is provided with a water supply component 5 connected to the water supply inner pipe 403. The water supply component 5 includes a fixing frame 505 located on the end face of the extraction tank 2. The fixing frame 505 is provided with a water supply main pipe 501 connected to an external water supply device. The water supply main pipe 501 is provided with a water supply branch pipe 502 connected to the water supply inner pipe 403. The water supply branch pipe 502 is provided with a rotary joint 504 and a constant pressure valve 503. like Figure 1 and Figure 8 As shown, by setting up a water supply component 5, the water supply component 5 is mainly composed of a water supply main pipe 501 that is connected to an external water supply device. Multiple water supply branch pipes 502 connected to the water supply inner pipe 403 are provided on its side, so that hot water can be distributed to the water supply inner pipe 403 through the water supply branch pipes 502. A constant pressure valve 503 is provided on the water supply branch pipe 502, which can automatically adjust according to the water pressure to make the water pressure of all water supply branch pipes 502 consistent, avoiding the problem of different water supply due to the location of the water supply branch pipes 502. At the same time, the rotary joint 504 in the water supply branch pipe 502 can be connected to the water supply inner pipe 403 in the rotating state to ensure the stability of water flow.

[0024] A sealing component 9 is provided on the support frame 1 corresponding to the opening end of the outer filter cartridge 401. The sealing component 9 is sealed and fitted to the inner wall of the outer filter cartridge 401. The sealing component 9 includes a support slide 901 provided in the support frame 1. A second connecting frame 902 is horizontally slidable on the support slide 901. A plurality of sealing plugs 903 that are horizontally aligned with the extraction cartridge 4 are rotatably provided on one side of the second connecting frame 902. A third hydraulic cylinder 904 is provided on the other side of the second connecting frame 902. A support plate 905 connected to the support frame 1 is provided at the tail end of the third hydraulic cylinder 904. like Figure 2 and Figure 12As shown, by setting the sealing component 9, when the extraction tank 2 is filled and compacted with coffee powder, the extraction tank 2 will be flipped to a horizontal state under the drive of the drive motor 3. At this time, the third hydraulic cylinder 904 in the sealing component 9 will drive the second connecting frame 902 to move. The second connecting frame 902 slides horizontally on the support slide 901, so that the sealing plug 903 at its front end is inserted into the extraction cylinder 4, and the sealing plug 903 is in contact with the inner wall of the extraction cylinder 4, so that the extraction cylinder 4 is in a closed state, preventing the coffee powder from being dispersed due to the soaking water flow during extraction, and preventing the coffee liquid from overflowing. The sealing plug 903 uses the rotational connection with the second connecting frame 902 to allow itself to rotate with the extraction cylinder 4, avoiding friction between the sealing plug 903 and the coffee powder.

[0025] The top of the support frame 1 is provided with a limiting slide rod 11, and a feeding component 7 is slidably provided on the limiting slide rod 11. A first hydraulic cylinder 12 is provided on the side of the feeding component 7. The first hydraulic cylinder 12 is connected to the support frame 1. A compaction component 8 is provided inside the feeding component 7. The feeding component 7 includes a dispensing tank 701. The side of the dispensing tank 701 is provided with a positioning ear plate 702 that slides vertically with the limiting slide rod 11, and a support ear plate 703 provided on the first hydraulic cylinder 12. A coffee powder conveying pipe 10 connected to an external conveying device is provided on the dispensing tank 701. A feeding cylinder 704 that is vertically aligned with the extraction cylinder 4 is provided below the dispensing tank 701. like Figure 1 and Figure 9 As shown, by setting up the feeding component 7, before preparing for the feeding operation, the first hydraulic cylinder 12 will lift the feeding component 7 upward. At this time, the feeding component 7 will not affect the flipping of the extraction tank 2. When the extraction tank 2 drives the extraction cylinder 4 to flip to a vertical state, the first hydraulic cylinder 12 will reset, causing the feeding component 7 to fall and dock with the extraction cylinder 4. The feeding component 7 consists of a dispensing tank 701 for collecting coffee powder and a feeding cylinder 704 whose position is aligned with the extraction cylinder 4. When feeding, the coffee powder conveying pipe 10 sends the coffee powder into the dispensing tank 701, and then the coffee powder enters the extraction cylinder 4 through the feeding cylinder 704 at the bottom of the dispensing tank 701. At this time, the coffee powder sent into the extraction cylinder 4 is not compacted, so its height will be flush with the top opening of the feeding cylinder 704. This method can make the coffee powder quickly fill multiple extraction cylinders 4, thereby improving the feeding efficiency.

[0026] The compaction component 8 includes a second hydraulic cylinder 801 mounted on the dispensing tank 701. A first connecting frame 802 is provided below the second hydraulic cylinder 801. The first connecting frame 802 is provided with a number of pressure rods 803 that are the same as those in the extraction cylinder 4. A pressure plate 804 that fits against the inner wall of the extraction cylinder 4 is provided below the pressure rods 803. like Figure 9 and Figure 10As shown, by setting up the pressure rod 803 and the pressure plate 804, after the coffee powder is filled into the extraction cylinder 4 and the feeding cylinder 704, the second hydraulic cylinder 801 will drive the first connecting frame 802 to move downward. The first connecting frame 802 will then drive the pressure plate 804 to extend into the feeding cylinder 704 through the pressure rod 803. The pressure plate 804 will squeeze the coffee powder in the feeding cylinder 704 into the extraction cylinder 4, making the coffee powder form a cake, ensuring the coffee powder is compact and preventing the formation of water channels during extraction. In addition, when the feeding cylinder 704 is not connected to the extraction cylinder 4, the pressure plate 804 will not move out of the feeding cylinder 704, which can prevent coffee powder from leaking out. Only when the feeding cylinder 704 is connected to the extraction cylinder 4 will the pressure plate 804 move out of the feeding cylinder 704 to allow the coffee powder to be fed. Figure 10 As shown, the top of the pressure plate 804 is tapered, which prevents coffee powder from accumulating on the top of the pressure plate 804.

[0027] The dispensing tank 701 is provided with a plurality of dispensing components 705 covering the feeding cylinder 704. The dispensing components 705 include dispensing plates 7051 rotatably disposed in the dispensing tank 701. When the dispensing plates 7051 are stationary, their positions are offset from the feeding cylinder 704, and adjacent dispensing plates 7051 are offset from each other. A fixing plate 7053 is provided under the dispensing tank 701. A servo motor 7054 that is drively connected to the dispensing plates 7051 is provided in the fixing plate 7053. like Figure 11 As shown, by setting a dispensing plate 7051 and a servo motor 7054, the dispensing plate 7051 is rotatably installed inside the feeding tank and can rotate under the drive of the servo motor 7054. When rotating, the dispensing plate 7051 will push the coffee powder in the feeding tank, so that the accumulated powder can move into the unfilled feeding cylinder 704, avoiding the problem of uneven distribution of coffee powder. Furthermore, by using the method of offset setting of the dispensing plate 7051 from the feeding cylinder 704 and driving it with the servo motor 7054, the dispensing plate 7051 is always offset from the feeding cylinder 704 when it stops, so as to avoid affecting the vertical movement of the pressure rod 803.

[0028] A synchronous pulley 7052 is provided under the material distribution plate 7051, and a synchronous belt 7056 is provided on the outer side of the synchronous pulley 7052. An outer tensioning pulley 7055 that rotatably fits against the outer side of the synchronous belt 7056 is provided under the material distribution tank 701. like Figure 11As shown, by setting a synchronous belt 7056 and a synchronous pulley 7052, the synchronous belt 7056 and the synchronous pulley 7052 have meshing teeth and grooves, which can drive and connect multiple material distribution plates 7051, so that the material distribution plates 7051 can rotate synchronously, ensuring uniform material distribution. Furthermore, the synchronous belt 7056 and the synchronous pulley 7052 can achieve silent transmission while avoiding the problem of elastic slippage. An outer tensioning pulley 7055 is provided on the outer side of the synchronous belt 7056, the purpose of which is to change the wrap angle between the synchronous belt 7056 and the synchronous pulley 7052, so as to avoid the problem of transmission being affected due to the wrap angle being too small.

[0029] A conveyor belt 13 is provided inside the support frame 1 at the position corresponding to the sealing component 9 and the opening of the extraction cylinder 4, and rigid partitions are provided at equal intervals on the conveyor belt 13; like Figure 1 and Figure 2 As shown, by setting up a conveyor belt 13, the conveyor belt 13 moves to the outside of the support frame 1. After the coffee powder is extracted, the sealing part 9 will separate from the extraction cylinder 4. Then the extraction tank 2 will flip the opening of the extraction cylinder 4 downward. At this time, due to gravity, the extracted coffee cake will slide out of the extraction cylinder 4 and fall onto the conveyor belt 13. The conveyor belt 13 will then remove the coffee cake. The rigid baffle set on the conveyor can increase the friction with the coffee cake and prevent the coffee cake from slipping on the conveyor belt 13. In addition, a vibration motor can be set on the extraction tank 2 so that it can actively vibrate to remove the coffee cake.

[0030] Working principle: The drive motor 3 rotates the extraction tank 2 to a vertical position. Then, the feeding component 7 feeds coffee powder into the extraction cylinder 4, and the powder is compressed into a cake by the compaction component 8. Then, the extraction tank 2 rotates to a horizontal position, and the sealing component 9 seals the opening of the extraction cylinder 4. Subsequently, the drive component 6 drives the extraction cylinder 4 to rotate at a constant speed. At the same time, the water supply component 5 delivers high-temperature hot water to the water supply inner pipe 403. The hot water flows into the inner filter cylinder 402 through the water outlet 404, and then flows through the coffee cake and the outer filter cylinder 401 under the action of gravity, and gathers at the bottom of the extraction tank 2. Finally, it is discharged from the coffee liquid outlet 14.

[0031] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
