Description

Technical Field

[0001] The present application relates to the technical field of coffee powder screening, and in particular to a freeze-dried coffee powder grading and screening device. Background Art

[0002] Freeze-dried coffee powder is made using freeze-drying technology. The production process involves freezing the coffee extract into a solid form at low temperatures, then allowing the water in the extract to sublime in a vacuum environment, resulting in dry coffee powder.

[0003] Freeze-dried coffee powder usually needs to be screened to ensure that there are no residual foreign matter, lumps or oversized particles in the coffee powder, to improve the purity of the product, and to screen out fine particles or oversized particles that do not meet the standards.

[0004] For example, patent publication number CN219292018U discloses a graded filtration device with a vibration function, comprising a filter box, a power cover, two filter screens, a drive motor, a power wheel, a transmission wheel, a rotating shaft, and a semicircular plate. This device addresses the poor performance of existing single-stage sand filtration devices and improves the filtration efficiency.

[0005] When the aforementioned patented grading filter device is in use, the filter screens are hinged to the inner wall of the filter box via pins. However, after prolonged use, the filter screens may become clogged. Although the aforementioned patent provides a cleaning door on the side of the filter box, the cleaning door is relatively narrow. Therefore, when cleaning the filter screens, only the partially clogged areas on the filter screens can be cleaned, resulting in a relatively constant cleaning problem. Therefore, a freeze-dried coffee powder grading and screening device is needed to solve the above problem.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

However, when the filter screen plates are used for a long time, they will become clogged. Although the above-mentioned patent provides a cleaning door on the side of the filter box, the cleaning door is relatively narrow, so when cleaning the filter screen plate, only part of the clogged area on the filter screen plate can be cleaned, and the cleaning is relatively unstable.

[0008] The technical solution adopted by the present application to solve its technical problem is: a freeze-dried coffee powder grading and screening device. The device mainly comprises: a filter box with a cover plate hinged on it; a screening assembly installed in the filter box, the screening assembly comprising: a first mounting frame hinged in the filter box; a second mounting frame hinged in the filter box; a spring mounted on the first mounting frame and the second mounting frame; a fixing plate mounted on the inner wall of the filter box, both the first mounting frame and the second mounting frame having buckle slots; a filter plate placed on the buckle slots; a fixing assembly mounted on the buckle slots, the fixing assembly comprising: four sets of screws mounted at the four corners of the buckle slots, the filter plate having holes formed on it; and a pressing frame mounted on the four sets of screws, each of which has butterfly nuts threadedly connected to it.

[0009] Furthermore, a filling hopper is installed on the cover plate.

[0010] Furthermore, a handle is installed on the cover.

[0011] Furthermore, two sets of blanking plates are installed on the filter box.

[0012] Furthermore, a vibration assembly is installed on the side of the filter box, and the vibration assembly includes a box body installed on the side of the filter box, a motor is installed in the box body, a power wheel is installed on the output end of the motor, a transmission wheel is installed on the bearing on the side of the filter box, and a belt is connected between the transmission wheel and the power wheel;

[0013] The power wheel and the transmission wheel both have a rotating shaft, and cams are installed on the rotating shafts of the power wheel and the transmission wheel.

[0014] The beneficial effect of the present application is that the present application provides a freeze-dried coffee powder grading and screening device, which can facilitate the disassembly and cleaning of the filter plate through the arrangement of a cover plate, a first mounting frame, a second mounting frame, a filter plate, a sleeve hole, a buckle groove, a screw, a pressure frame and a butterfly nut.

[0027] like Figure 1-Figure 5 As shown, the present application provides a freeze-dried coffee powder grading and screening device, comprising a filter box 1, a cover plate 102 hingedly connected to the filter box 1, the cover plate 102 being used to seal the filter box 1, and a filling hopper 103 fixedly mounted on the cover plate 102, the filling hopper 103 being used to inject freeze-dried coffee powder into the filter box 1;

[0028] A handle 104 is fixedly mounted on the cover 102 and is used to open the cover 102 ;

[0029] A screening assembly 3 is installed in the filter box 1. The screening assembly 3 is used to grade and screen the freeze-dried coffee powder. The screening assembly 3 includes a first mounting frame 301 that is hingedly mounted in the filter box 1, and a second mounting frame 302 is hingedly mounted in the filter box 1 at the lower end of the first mounting frame 301.

[0030] A spring 303 is fixedly mounted on both the first mounting frame 301 and the second mounting frame 302. A fixing plate 304 is fixedly mounted on the inner wall of the filter box 1. One end of the spring 303 is connected to the fixing plate 304 to support one end of the first mounting frame 301 and the second mounting frame 302.

[0031] The first mounting frame 301 and the second mounting frame 302 are both provided with buckle slots 307. The buckle slots 307 are square in structure. Filter plates 305 are placed on the buckle slots 307. The two sets of filter plates 305 are suitable for performing graded filtration on the freeze-dried coffee powder.

[0032] It should be noted that the mesh of the filter plate 305 mounted on the first mounting frame 301 is larger than the mesh of the filter plate 305 mounted on the filter plate 305 , so as to be suitable for performing graded filtration on the freeze-dried coffee powder;

[0033] Two sets of blanking plates 101 are fixedly mounted on the filter box 1, and the two sets of blanking plates 101 are used to discharge the freeze-dried coffee powder sieved by the filter plates 305 on the first installation frame 301 and the second installation frame 302 respectively;

[0034] A fixing assembly 4 is mounted on the buckle slot 307. The fixing assembly 4 includes four sets of screws 401 fixedly mounted at the four corners of the buckle slot 307. A sleeve hole 306 is opened on the filter plate 305. The filter plate 305 is sleeved on the screws 401 through the sleeve hole 306 to initially restrict the filter plate 305.

[0035] A pressing frame 402 is sleeved on the four sets of screw rods 401, and a butterfly nut 403 is threadedly connected to the screw rods 401. The butterfly nut 403 is used to press the pressing frame 402 onto the filter plate 305 to fix the filter plate 305 in the buckle groove 307;

[0036] A vibration assembly 2 is fixedly mounted on the side of the filter box 1. The vibration assembly 2 is used to vibrate the filter plate 305. The vibration assembly 2 includes a box body 201 fixedly mounted on the side of the filter box 1. A square groove adapted to the size of the box body 201 is opened on the side of the filter box 1. A motor 202 is fixedly mounted in the box body 201. A power wheel 203 is fixedly mounted on the output end of the motor 202. A transmission wheel 204 is mounted on the bearing on the side of the filter box 1. A belt (not shown in the figure) is connected between the transmission wheel 204 and the power wheel 203.

[0037] The power wheel 203 and the transmission wheel 204 both have a rotating shaft, and cams 205 are fixedly mounted on the rotating shafts of the power wheel 203 and the transmission wheel 204. The cams 205 are located in the filter box 1. The two sets of cams 205 are in contact with the lower surfaces of the first installation frame 301 and the second installation frame 302, respectively. The power wheel 203 is adapted to rotate along with the output end of the motor 202 to drive the belt to move, thereby driving the transmission wheel 204 to rotate. The rotation of the cams 205 can cause the first installation frame 301 and the second installation frame 302 to vibrate up and down, thereby filtering the freeze-dried coffee powder.

[0038] Working principle:

[0039] During use, freeze-dried coffee powder is poured into the hopper 103, and then the motor 202 is started, which drives the power wheel 203 to rotate, and drives the transmission wheel 204 to rotate through the belt. Then, the operation of the power wheel 203 and the transmission wheel 204 drives the cam 205 to rotate, and the cyclic rotation of the cam 205 can continuously push up the two filter plates 305, so that the filter plates 305 vibrate and filter the freeze-dried coffee powder, and the filtered freeze-dried coffee powder is discharged through the discharge plate 101, thereby completing the graded filtration of the freeze-dried coffee powder.

[0040] When the filter plate 305 becomes clogged and the filtration effect is poor after long-term use, the cover plate 102 is rotated by holding the handle 104, and then the butterfly nut 403 is loosened to remove the pressing frame 402 and the filter plate 305 in turn, so that the two groups of filter plates 305 can be removed from the first mounting frame 301 and the second mounting frame 302 to clean the filter plates 305.

[0041] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
