Description

Technical Field

[0001] This utility model relates to the field of fruit processing technology, and in particular to a filtration device for grapefruit processing with multi-stage filtration effect. Background Technology

[0002] Grapefruit, a citrus fruit native to Southeast Asia, is large with a thick peel and juicy flesh. Varieties include white-fleshed and red-fleshed varieties. Rich in vitamin C, dietary fiber, and antioxidants, it offers benefits such as promoting cardiovascular health and aiding in blood sugar control. The flesh can be eaten fresh or used in cooking, while the peel can be made into preserves or used medicinally. Grapefruit is easy to store and low in calories, combining nutritional and health benefits. The production of grapefruit tea requires the extraction and filtration of grapefruit juice.

[0003] 1. In the existing technology, although the juice in the grapefruit pulp can be pressed a second time and the pressed grapefruit juice can be filtered, the grapefruit juice filtration process still relies on the grapefruit juice itself dripping from the top of the filter screen by its own weight. During this process, as the grapefruit juice filtration flow rate decreases, the subsequent grapefruit juice falls at a slower rate, thereby reducing the overall filtration efficiency of the grapefruit juice.

[0004] 2. In the existing technology, during the filtration process of grapefruit juice, although grapefruit residue on the top of the filter screen can be cleaned, this process only cleans the residue on the top of the filter screen. Some grapefruit residue located inside the filter screen cannot be cleaned well. Because this part of the grapefruit residue accumulates inside the filter screen, over time, the filtration speed will slow down, and this part of the residue is also more prone to deterioration, which is not conducive to the subsequent filtration process.

A second support ring is fixedly connected to the middle part of the inner chamber, and a fine filter screen is inserted inside the second support ring. A third support ring is fixedly connected to the lower part of the inner chamber, and an activated carbon filter layer is inserted inside the third support ring.

[0010] According to the aforementioned filtration device for grapefruit processing with multi-stage filtration effect, the coarse filter screen is tightly fitted to the inner wall of the chamber, the coarse filter screen is inserted into the chamber, an extraction device is provided in the middle of the coarse filter screen, an extraction device is provided in the middle of the fine filter screen, and an extraction device is provided in the middle of the activated carbon filter layer.

[0011] According to the aforementioned filtration device for grapefruit processing with multi-stage filtration effect, the compression device includes a frame, with connecting blocks fixedly connected to the four corners of the middle part of the frame, an air inlet hole extending through the top of the frame, an electric telescopic rod fixedly connected to the top of the frame, a pressing piston fixedly connected to the output end of the electric telescopic rod, and a docking ring fixedly connected to the bottom of the frame.

[0016] This utility model has the following beneficial effects:

[0017] 1. Compared with existing technologies, the pressing piston moves downward under the drive of the electric telescopic rod. With the sealing cover and valve closed, the downward movement of the pressing piston compresses the gas inside the frame and chamber. This compressed air causes the grapefruit juice to move downward quickly, thereby increasing the filtration speed of the grapefruit juice. Furthermore, when the pressing piston comes into contact with the coarse filter screen, the grapefruit residue inside is also squeezed a second time through the compression of the grapefruit residue. This achieves faster filtration of the grapefruit juice and improves efficiency.

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-4 This utility model provides a multi-stage filtration device for grapefruit processing, which includes a filter 1 and a compression device 2. A feeding device 3 is provided above the compression device 2. A pressure relief valve 4 is provided in the middle of the filter 1. A connecting ring 5 is provided at the bottom of the filter 1. A support foot 6 is fixedly connected to the bottom of the connecting ring 5. A discharge pipe 7 is provided below the filter 1. A valve 8 is installed in front of the discharge pipe 7.

[0030] The above structure, by providing a connecting ring 5, which is fixedly connected to the hopper body 10 and the supporting leg 6, enables the hopper body 10 to be supported by the connecting ring 5 and the supporting leg 6.

[0031] The discharge pipe 7 is fixedly connected to the silo body 10 and communicates with the inside of the silo body 10. A valve 8 is installed in front of the discharge pipe 7, which allows the operator to export the grapefruit juice inside the silo body 10 by controlling the valve 8.

[0032] The filter 1 includes a chamber 10, a pressure relief valve 4 installed in the middle of the chamber 10, a connecting ring 5 fixedly connected to the chamber 10, a discharge pipe 7 fixedly connected to the chamber 10, fixing blocks 11 fixedly connected to the four corners of the upper part of the chamber 10, a locking rod 12 rotatably connected to the middle of the fixing block 11, a locking nut 13 threadedly connected to the upper part of the locking rod 12, a docking groove 14 opened on the upper part of the chamber 10, a first sealing ring 15 slidably connected inside the docking groove 14, a first support ring 16 fixedly connected to the upper part of the interior of the chamber 10, and the upper part of the first support ring 16... The chamber 10 is equipped with a coarse filter 17. A second support ring 18 is fixedly connected to the center of the chamber body 10. A fine filter 19 is inserted into the center of the second support ring 18. A third support ring 110 is fixedly connected to the lower part of the chamber body 10. An activated carbon filter layer 111 is inserted into the center of the third support ring 110. The coarse filter 17 is tightly fitted to the inner wall of the chamber body 10. The coarse filter 17 is inserted into the chamber body 10. An extraction device 9 is provided in the center of the coarse filter 17, the center of the fine filter 19, and the center of the activated carbon filter layer 111.

[0033] The aforementioned structure, by incorporating a pressure relief valve 4, allows for pressure relief of the gas inside the frame 20 and chamber 10 when the valve 8 is closed and the piston 24 moves downward. If the compressed air level exceeds the required compression threshold, the valve 4 ensures the pressure inside the frame 20 and chamber 10 does not exceed the maximum pressure the device can withstand. Furthermore, in practical use, a fine filter screen is installed at the connection between the pressure relief valve 4 and the chamber 10 to prevent grapefruit residue from entering the valve 4.

[0034] With the docking groove 14 provided, the operator can install the frame 20 on top of the compartment 10. The connecting block 21 corresponds to the locking rod 12, allowing the operator to rotate the four locking rods 12 upwards and place them on the outside of the connecting block 21. The operator can then rotate the locking nut 13 to make the connecting block 21 tightly contact the locking nut 13. The locking torque of the four locking nuts 13 is the same, thus completing the connection between the frame 20 and the compartment 10.

[0035] A first sealing ring 15 is provided between the frame 20 and the chamber 10. After installation, the first sealing ring 15 is deformed by the compression between the docking ring 25 and the docking groove 14. The airtightness between the frame 20 and the chamber 10 is greatly improved by the deformation of the first sealing ring 15.

[0036] By incorporating a coarse filter 17 and a fine filter 19, the grapefruit juice, after being blended by a high-speed blender, is filtered to remove impurities. This two-stage filtration process results in a clearer and purer grapefruit juice. An activated carbon filter layer 111 then performs a third filtration, removing impurities, odors, pigments, and harmful substances, thus achieving multi-stage filtration of the grapefruit juice.

[0037] The compression device 2 includes a frame 20, with connecting blocks 21 fixedly connected to the four corners of the middle part of the frame 20. The connecting blocks 21 correspond to the locking rod 12 and are in close contact with the locking nut 13. The mating ring 25 corresponds to the mating groove 14. An air inlet 22 is provided through the top of the frame 20. An electric telescopic rod 23 is fixedly connected to the top of the frame 20. A pressing piston 24 is fixedly connected to the output end of the electric telescopic rod 23. The mating ring 25 is fixedly connected to the bottom of the frame 20. The feeding device 3 includes a feeding pipe 31. A sealing cap 32 is threadedly connected to the top of the feeding pipe 31. A second sealing ring 33 is slidably connected to the bottom of the sealing cap 32. The feeding pipe 31 is fixedly connected to the frame 20.

[0038] The above structure, driven by the electric telescopic rod 23, causes the pressing piston 24 to move downward. With the sealing cover 32 and valve 8 closed, the downward movement of the pressing piston 24 compresses the gas inside the frame 20 and the chamber 10. Under the action of this compressed air, the grapefruit juice can move downward quickly, thereby increasing the filtration speed of grapefruit juice. When the pressing piston 24 comes into contact with the coarse filter screen 17, the grapefruit juice inside the grapefruit residue is also squeezed a second time through the squeezing of the grapefruit residue by both of them.

[0039] By providing an air inlet 22, air can enter the upper part of the chamber 10 during the movement of the compression piston 24.

[0040] The extraction device 9 includes a connecting chamber 91, which is fixedly connected to the coarse filter screen 17. A slider 92 is slidably connected inside the connecting chamber 91, and a pull block 93 is fixedly connected above the slider 92. The connecting chamber 91 is fixedly connected to the fine filter screen 19 and the activated carbon filter layer 111.

[0041] The above structure, by pulling the pull block 93, causes the slider 92 to move upward. When the slider 92 contacts the connecting chamber 91, the slider 92 drives the connecting chamber 91 to move upward synchronously, thereby achieving the upward pulling of the connecting chamber 91.

[0042] The coarse filter 17 is fixedly connected to the connecting chamber 91, and the coarse filter 17 is tightly attached to the inner wall of the chamber body 10. The coarse filter 17 is inserted into the chamber body 10, so that the coarse filter 17 can be disassembled by pulling the pull block 93.

[0043] The fine filter 19 is fixedly connected to the connecting compartment 91 and inserted into the inside of the second support ring 18, allowing it to be disassembled by pulling the pull block 93. Furthermore, the diameter of the fine filter 19 is smaller than that of the coarse filter 17, and also smaller than the inner diameter of the first support ring 16, allowing the fine filter 19 to pass through the inside of the first support ring 16, thus enabling its disassembly.

[0044] The activated carbon filter layer 111 is fixedly connected to the connecting chamber 91 and inserted into the interior of the third support ring 110. This allows the activated carbon filter layer 111 to be disassembled by pulling the pull block 93. The diameter of the activated carbon filter layer 111 is smaller than the diameter of the fine filter screen 19 and smaller than the inner diameter of the second support ring 18, allowing the activated carbon filter layer 111 to pass through the interior of the second support ring 18 and, similarly, through the interior of the first support ring 16, thus completing the disassembly of the activated carbon filter layer 111.

[0045] In summary, operators can disassemble the coarse filter 17, the fine filter 19, and the activated carbon filter layer 111, thereby enabling more thorough cleaning of the coarse filter 17 and the fine filter 19, making them cleaner, and replacing the activated carbon filter layer 111, thus ensuring the effectiveness of filtration.

[0046] Working principle: This multi-stage filtration device for grapefruit processing first pours the grapefruit juice, which has been crushed by the blender, into the feed pipe 31, and then tightens the sealing cap 32. At this time, the switch of the electric telescopic rod 23 is turned on, causing the pressing piston 24 to move downward. Under the action of the pressing piston 24 slowly descending, the grapefruit juice moves downward quickly. When the pressing piston 24 comes into contact with the extraction device 9, the grapefruit juice is squeezed out to a great extent by the two pressing grapefruit residues. After filtration is completed, the pressing piston 24 is returned to its original position and the valve 8 is opened. At this time, the filtered grapefruit juice can be obtained.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
