Description

Technical Field

[0001] The present invention relates to the technical field of fruit juice production, and particularly to a degasser for food fruit juice processing. Background Art

[0002] During the production process of blueberry juice, air and unwanted gases are usually mixed into the product. These gases usually cause problems such as oxidation, discoloration, inconsistency, unpleasant odor, and filling difficulties. A fruit juice degasser is a device specifically used to remove free and dissolved gases in fruit juice. At present, many degassers use the method of nitrogen filling for degassing. The reaction process between nitrogen and the gases in the fruit juice is slow, the degassing efficiency is low, and the discharged gases from the fruit juice are difficult to discharge and are easily mixed with the fruit juice again.

[0003] The patent with the patent number CN202121548151.2 discloses a degasser for food fruit juice processing. The air inlet pipe of this patent inputs nitrogen into the nozzle, so that the airflow ejected by the nozzle exerts a thrust on the fruit juice and the stirring blade. Thus, the stirring blade rotates at one end of the support column through the mounting ring, and the stirring blade pushes the fruit juice to flow. Then, nitrogen and the gases in the fruit juice are fully combined, and the gases in the fruit juice escape, realizing the function of increasing the gas volume in the fruit juice while being able to push the stirring blade to rotate. And the residues in the fruit juice are blocked by the filter screen, and the fruit juice descends along the guiding surface of the guiding plate. Thus, both the airflow and the fruit juice flow in the reaction chamber, and the tail gas is discharged through the air outlet pipe. At the same time, the effective area between the fruit juice and the airflow increases, and then the gases in the fruit juice are fully volatilized, realizing the function of increasing the effective contact area between the gases in the fruit juice and the air. Although this patent solves the above problems, there are still problems such as the slow reaction process between nitrogen and the gases in the fruit juice, low degassing efficiency, and slow discharge speed of the gases separated from the fruit juice. Therefore, it is very necessary to design a degasser for food fruit juice processing that uses the method of vacuum degassing, has high degassing efficiency, and enables the gases to be quickly discharged through the circulating flow of the fruit juice without remixing with the fruit juice. Summary of the Invention

[0004] The purpose of the present invention is to provide a degasser for food fruit juice processing to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A degassing machine for food juice processing, comprising a bottom plate. The bottom plate further includes a degassing device. The degassing device includes a vacuum suction structure and a siphon circulation structure. The vacuum suction structure includes a vacuum pump, a degassing tank, and a fixed seat. The vacuum pump is arranged above the bottom plate. The degassing tank is fixedly connected to the left side of the vacuum pump. The fixed seat is fixedly connected to the lower side of the vacuum pump. The siphon circulation structure includes a sleeve, a rubber sealing ring, an L-shaped hose, a liquid storage tank, a liquid outlet rotating barrel, an infusion tube, an automatic exhaust valve, and a check valve. The sleeve is fixedly connected to the right side of the degassing tank. The rubber sealing ring is sleeved on the top of the sleeve. The L-shaped hose is sleeved inside the sleeve. The liquid storage tank is fixedly connected above the bottom plate. The liquid outlet rotating barrel is sleeved inside the liquid storage tank. The infusion tube is fixedly connected to the left side of the liquid storage tank. The automatic exhaust valve is fixedly connected to the upper surface of the infusion tube. The check valve is fixedly connected inside the infusion tube. The rubber sealing ring is sleeved on one end of the L-shaped hose. The fixed seat is fixedly connected to the top of the liquid storage tank. The infusion tube is fixedly connected to the top of the degassing tank. When juice is continuously input into the degassing tank, its liquid level continuously rises. When the juice liquid level is higher than the sleeve, it will flow out of the sleeve. Before the staff starts the device, the L-shaped hose is inserted into the sleeve, and then the L-shaped hose is connected to the sleeve with the rubber sealing ring. The juice flows into the L-shaped hose, generating negative pressure inside it. At this time, the pressure at the top of the L-shaped hose is low, and the pressure at the bottom is high. Also, because the liquid will flow from the high-pressure area to the low-pressure area, the juice will be sucked to the inflection point at the top of the L-shaped hose. After the juice flows through the inflection point, it falls due to its own gravity and thus flows into the liquid storage tank, and then flows into the infusion tube through the liquid storage tank. At this time, the check valve is in a closed state, and the juice can only stay in the infusion tube. When the juice in the infusion tube is full, it can lift the float in the automatic exhaust valve, making the automatic exhaust valve unable to discharge gas. Then the check valve is opened. After the juice passes through the check valve, it is blocked by the check valve and cannot flow back. Finally, it flows back into the degassing tank through the infusion tube, completing the circulating flow. The circulating flow makes the degassed juice and the non-degassed juice remix, diluting the gas, increasing the degassing speed, and improving the degassing efficiency. When the juice passes through the check valve, the float in the automatic exhaust valve drops, and when the juice flows through the first impeller, it drives the first impeller to rotate. The first impeller drives the first rotating shaft to rotate, and the first rotating shaft then drives the liquid outlet rotating barrel to rotate. When the notch opened on one side of the liquid outlet rotating barrel rotates to align with the infusion tube nozzle, the juice flows out; otherwise, the juice cannot flow out, enabling the juice to intermittently flow into the infusion tube, ensuring that there is a period of hollow time in the infusion tube, facilitating the exhaust of the automatic exhaust valve, and thus further improving the degassing efficiency.

[0006] According to the above technical solution, a filtering device is provided below the L-shaped hose. The filtering device includes a sieving structure and a dynamic filtering structure. The sieving structure includes a water pump, a fluid propulsion chamber, a first impeller, a rising pipe, and a filter plate. The water pump is fixedly connected below the L-shaped hose. The fluid propulsion chamber is opened at the bottom of the liquid storage tank. The first impeller is rotatably connected to the bottom surface of the fluid propulsion chamber. The bottom end of the rising pipe is fixedly connected to the right side of the liquid storage tank. The filter plate is slidably connected to the inner wall of the liquid storage tank. The dynamic filtering structure includes a compression spring, a first mounting plate, a first rotating shaft, and blades. The compression spring is fixedly connected below the filter plate. The first mounting plate is fixedly connected to the bottom end of the compression spring. The first rotating shaft is fixedly connected to the top end of the first impeller. The blades are fixedly connected to the surface of the first rotating shaft. The water pump is fixedly connected to the left side of the liquid storage tank. The first mounting plate is fixedly connected to the inner wall of the liquid storage tank. The first rotating shaft penetrates through the top end of the fluid propulsion chamber. The first rotating shaft is fixedly connected to the inner side of the liquid outlet rotating barrel. The top end of the rising pipe is fixedly connected to the top surface of the liquid storage tank. The fruit juice flows into the water pump from the L-shaped hose. The water pump pressurizes the fruit juice and sprays the fruit juice into the fluid propulsion chamber. After the fruit juice is sprayed into the fluid propulsion chamber, it impacts the leaf surface of the first impeller, pushing it to rotate, and then flows into the rising pipe. When the fruit juice reaches the top end of the rising pipe, it rushes into the liquid storage tank due to gravity. When the fruit juice passes through the filter plate, the fruit residues will be filtered out by the filter plate, improving the taste. The fruit juice impacts the filter plate and pushes the filter plate to compress the compression spring. After the compression spring is compressed, it rebounds, causing the filter plate to vibrate. The vibration of the filter plate enables the fruit juice to flow down quickly from the filter holes, and at the same time enables the fruit juice and the fruit residues to be separated more quickly, improving the filtering effect. The fruit juice flows through the filter plate into the liquid outlet rotating barrel. The first rotating shaft drives the liquid outlet rotating barrel to rotate to generate centrifugal force, causing the small fruit residues that have not been filtered out in the fruit juice to precipitate downward. At the same time, when the first rotating shaft rotates, it also drives the blades to rotate. The blades stir the fruit juice, expanding the gaps between the fruit juice molecules, making it easier for the small fruit residues to precipitate, further promoting the filtering effect, improving the taste and processing quality of the fruit juice. When the small fruit residues precipitate to the bottom of the liquid outlet rotating barrel, the fruit juice will flow out from the notch opened on one side of the top of the liquid outlet rotating barrel. And only when the notch of the liquid outlet rotating barrel aligns with the pipe orifice of the infusion pipe after rotating one circle, the fruit juice can flow out, providing a certain time for precipitation and enabling the fruit juice to be fully filtered.

[0007] According to the above technical solution, a stirring device is provided on the left side of the water pump, and the stirring device includes a stirring structure and a homogenizing structure, and the stirring structure includes a partition, a second impeller, a liquid outlet, a second rotating shaft, and a stirring paddle. The partition is fixedly connected to the inner wall of the top of the degassing tank, and the second impeller is rotatably connected to the inner wall of the top of the degassing tank. The liquid outlet is arranged on the inner side of the partition, and the second rotating shaft is fixedly connected to the bottom end of the second impeller. The stirring paddle is fixedly connected to the surface of the second rotating shaft. The homogenizing structure includes a paddle plate, a second mounting plate, a homogenizing impeller, and a paddle wheel. The paddle plate is fixedly connected to the surface of the second rotating shaft, the second mounting plate is fixedly connected to the inner wall of the bottom of the degassing tank, the homogenizing impeller is rotatably connected to the upper surface of the second mounting plate, the paddle wheel is fixedly connected to the middle part of the homogenizing impeller, the second impeller rotates and penetrates to the lower surface of the partition, the homogenizing impeller is rotatably connected to the lower surface of the partition, a bump is protruded on the surface of the paddle wheel, and the paddle plate is transmission-connected to the bump, and the water pump pushes the juice to keep The juice continues to flow. When the juice flows back into the degassing tank from the infusion tube, it will be blocked by the partition and flow on the top of the degassing tank. At this time, the flowing juice drives the second impeller to rotate, and the second impeller drives the second rotating shaft to rotate. The second rotating shaft drives the stirring paddle to rotate. The stirring paddle stirs the juice in the degassing tank. Because the gas has a smaller density than the juice, the gas in the juice is in an ascending state. Therefore, after the juice is muddied, the gas inside it is subject to less resistance from the juice, and rises faster, which helps to degas faster. The stirring paddle rotates in the center of the degassing tank. The juice around the degassing tank is weakly stressed, and the rising speed of the gas around it is inconsistent with that of the center. Therefore, a homogenizing impeller is arranged around the degassing tank. When the second rotating shaft rotates, it drives the dial plate to rotate. When the dial rotates, it hits the dial wheel, thereby rotating the dial wheel. The dial wheel drives the homogenizing impeller to rotate. The homogenizing impeller stirs the juice around the degassing tank, which speeds up the rising speed of the gas around it, further promoting the degassing efficiency, making the juice degassing more uniform, and producing better quality.

[0008] According to the above technical solution, a liquid discharging device is provided at the bottom of the second rotating shaft. The liquid discharging device includes a pushing structure and a rotating structure. The pushing structure includes a cam, a pushing member, and a scraper. The cam is movably connected to the surface of the second rotating shaft. The pushing member is slidably connected to the lower surface of the cam. The scraper is fixedly connected to the bottom end of the pushing member. The rotating structure includes a connecting rod, a through groove, a pressing block, and a return spring. The connecting rod is fixedly connected to both sides of the cam. The through groove is opened on both sides of the bottom end of the second rotating shaft. The pressing block is fixedly connected to the inner side of the pushing member. The return spring is fixedly connected to the inner wall of the bottom end of the through groove. The connecting rod is fixedly connected to the inner wall of the bottom of the degassing tank. The pushing member is sleeved on the surface of the bottom end of the second rotating shaft. The pressing block is slidably connected to the inner side of the through groove. The bottom plate of the pressing block is fixedly connected to the top end of the return spring. A liquid discharging cylinder is fixedly connected to the bottom end of the degassing tank, and the scraper is slidably connected to the inner wall of the liquid discharging cylinder. During the juice degassing process, the valve in the liquid discharging cylinder below the degassing tank is closed to prevent the juice from flowing out during the degassing process. However, some fruit residues will precipitate downward inside the degassing tank and block the liquid discharging cylinder. Therefore, a scraper is provided above the liquid discharging cylinder. When the second rotating shaft rotates, it drives the pushing member to rotate. When the pushing member rotates, it touches the arc surface of the cam and extends. After the pushing member extends, it compresses the return spring, and the return spring drives the pushing member to retract and reset, so that the pushing member expands and contracts. The expansion and contraction of the pushing member drives the expansion and contraction of the scraper, and the expansion and contraction of the scraper scrapes off the fruit residues adhering to the inner wall of the liquid discharging cylinder, improving the liquid discharging speed and accelerating the production efficiency. Moreover, the pressing block on the inner side of the pushing member is slidably connected in the through groove, ensuring that the scraper expands, contracts, rotates simultaneously. The expansion, contraction, and rotation of the scraper increase the friction force when contacting the inner wall of the liquid discharging cylinder, making the scraping effect better, further preventing the blocking of the discharging cylinder, and enhancing the liquid discharging speed.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: In the present invention, by providing a sleeve, an L-shaped hose, a liquid storage tank, and a liquid discharging rotating barrel, after the juice passes through the check valve, the float in the automatic exhaust valve drops, and the juice drives the first impeller to rotate when flowing through the first impeller. The first impeller drives the first rotating shaft to rotate, and the first rotating shaft drives the liquid discharging rotating barrel to rotate. When the notch opened on one side of the liquid discharging rotating barrel rotates and aligns with the nozzle of the infusion tube, the juice flows out; otherwise, the juice cannot flow out, enabling the juice to intermittently flow into the infusion tube, ensuring that there is a period of hollow time in the infusion tube, facilitating the exhaust of the automatic exhaust valve, and thus further improving the degassing efficiency. The present invention is provided with a fluid propulsion chamber, a first impeller, a first rotating shaft, and blades. When the first rotating shaft rotates, the blades are also driven to rotate. The blades stir the juice, enlarge the gaps between juice molecules, and make it easier for fine fruit residues to precipitate, further promoting the filtering effect, and improving the taste and processing quality of the juice. When the fine fruit residues are precipitated to the bottom of the liquid outlet rotating barrel, the juice will flow out from the notch opened on one side of the top of the liquid outlet rotating barrel, and the juice can only flow out when the notch of the liquid outlet rotating barrel is aligned with the infusion tube orifice after rotating one circle, which provides a certain time for precipitation and enables the juice to be fully filtered. The present invention is provided with a paddle plate, a second mounting plate, a homogenizing impeller and a paddle wheel. When the second rotating shaft rotates, the paddle plate is driven to rotate. When the paddle plate rotates, it hits the paddle wheel, so that the paddle wheel rotates. The paddle wheel drives the homogenizing impeller to rotate. The homogenizing impeller stirs the juice around the degassing tank, so that the rising speed of the gas around it is accelerated, the degassing efficiency is further promoted, and the degassing of the juice is more uniform, and the production quality is better. The present invention is provided with a pushing member, a through groove, a pressure block and a reset spring. The extension and retraction of the pushing member drives the scraper to extend and retract. The extension and retraction of the scraper scrapes away the fruit residue adhering to the inner wall of the liquid discharge cylinder, thereby improving the liquid discharge speed and accelerating the production efficiency. The pressure block on the inner side of the pushing member is slidably connected in the through groove, which ensures that the scraper extends and rotates at the same time. When the scraper extends and rotates, the contact with the inner wall of the liquid discharge cylinder increases the friction force, so that the scraping effect is better, the blockage of the discharge cylinder is further prevented, and the liquid discharge speed is improved.

DETAILED DESCRIPTION

[0012] 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.

[0013] See also Figures 1-4, an embodiment of the present invention is: a degasser for food juice processing, including a bottom plate 1. The bottom plate 1 further includes a degassing device 2. The degassing device 2 includes a vacuum suction structure and a siphon circulation structure. The vacuum suction structure includes a vacuum pump 21, a degassing tank 22, and a fixing seat 23. The vacuum pump 21 is arranged above the bottom plate 1. The degassing tank 22 is fixedly connected to the left side of the vacuum pump 21. The fixing seat 23 is fixedly connected to the lower side of the vacuum pump 21. The vacuum pump 21 extracts the gas in the degassing tank 22 to make the degassing tank 22 reach a vacuum state. The gas free and dissolved in the juice diffuses towards the vacuum. The gas diffused to the top of the degassing tank 22 is then sucked by the vacuum pump 21 to achieve degassing. When the vacuum pump 21 continuously sucks air, the gas in the juice will continuously diffuse and then be sucked by the vacuum pump 21 to achieve continuous degassing. The siphon circulation structure includes a sleeve 24, a rubber sealing ring 25, an L-shaped hose 26, a liquid storage tank 27, a liquid outlet rotating barrel 28, an infusion tube 29, an automatic exhaust valve 210, and a check valve 211. The sleeve 24 is fixedly connected to the right side of the degassing tank 22. The rubber sealing ring 25 is sleeved on the top of the sleeve 24. The L-shaped hose 26 is sleeved inside the sleeve 24. The liquid storage tank 27 is fixedly connected above the bottom plate 1. The liquid outlet rotating barrel 28 is sleeved inside the liquid storage tank 27. The infusion tube 29 is fixedly connected to the left side of the liquid storage tank 27. The automatic exhaust valve 210 is fixedly connected to the upper surface of the infusion tube 29. The check valve 211 is fixedly connected inside the infusion tube 29. The rubber sealing ring 25 is sleeved with one end of the L-shaped hose 26. The fixing seat 23 is fixedly connected to the top of the liquid storage tank 27. The infusion tube 29 is fixedly connected to the top of the degassing tank 22. When the juice is continuously input into the degassing tank 22, its liquid level continuously rises. When the juice liquid level is higher than the sleeve 24, it will flow out of the sleeve 24. Before the staff starts the device, the L-shaped hose 26 is inserted into the sleeve 24, and then the L-shaped hose 26 is connected to the sleeve 24 with the rubber sealing ring 25. The juice flows into the L-shaped hose 26 and generates negative pressure inside it. At this time, the pressure at the top of the L-shaped hose 26 is low and the pressure at the bottom is high. Also, because the liquid will flow from the high-pressure place to the low-pressure place, the juice will be sucked to the inflection point at the top of the L-shaped hose 26. After the juice flows through the inflection point, it falls due to its own gravity and thus flows into the liquid storage tank 27, and then flows into the infusion tube 29 through the liquid storage tank 27. At this time, the check valve 211 is in a closed state, and the juice can only stay in the infusion tube 29. When the juice in the infusion tube 29 is full, it can lift the float in the automatic exhaust valve 210, making the automatic exhaust valve 210 unable to exhaust air. Then the check valve 211 is opened. The juice is blocked by the check valve 211 and cannot flow back after passing through the check valve 211, and finally flows back into the degassing tank 22 through the infusion tube 29 to complete the circulating flow. The circulating flow makes the degassed juice and the non-degassed juice remix, dilutes the gas, improves the degassing speed, and enhances the degassing efficiency. When the juice passes through the check valve 211, the float in the automatic exhaust valve 210 drops, and the juice drives the first impeller 33 to rotate when flowing through the first impeller 33. The first impeller 33 drives the first rotating shaft 38 to rotate, and the first rotating shaft 38 then drives the liquid outlet rotating barrel 28 to rotate.When the notch opened on one side of the liquid outlet rotary barrel 28 rotates and aligns with the nozzle of the infusion tube 29, the juice flows out; otherwise, the juice cannot flow out, enabling the juice to intermittently flow into the infusion tube 29, ensuring that there is a period of hollow time in the infusion tube 29, facilitating the exhaust of the automatic exhaust valve 210, and thus further improving the degassing efficiency; Working principle: The vacuum pump 21 extracts the gas in the degassing tank 22 to make the degassing tank 22 reach a vacuum state. The gas free and dissolved in the juice diffuses towards the vacuum. The gas diffused to the top of the degassing tank 22 is then sucked by the vacuum pump 21 to achieve degassing. When the vacuum pump 21 continuously sucks air, the gas in the juice will continuously diffuse and be sucked by the vacuum pump 21 to achieve continuous degassing. When the juice is continuously input into the degassing tank 22, its liquid level continuously rises. When the juice liquid level is higher than the sleeve 24, it will flow out of the sleeve 24. Before the staff starts the device, the L-shaped hose 26 is inserted into the sleeve 24, and then the L-shaped hose 26 is connected to the sleeve 24 with the rubber sealing ring 25. The juice flows into the L-shaped hose 26 and generates negative pressure inside it. At this time, the pressure at the top of the L-shaped hose 26 is low and the pressure at the bottom is high. Also, because the liquid will flow from the high-pressure area to the low-pressure area, the juice will be sucked to the top inflection point of the L-shaped hose 26. After the juice flows through the inflection point, it falls due to its own gravity and thus flows into the liquid storage tank 27, and then flows into the infusion tube 29 through the liquid storage tank 27. At this time, the check valve 211 is in the closed state, and the juice can only stay in the infusion tube 29. When the juice in the infusion tube 29 is full, it can lift the float in the automatic exhaust valve 210, making the automatic exhaust valve 210 unable to exhaust. Then the check valve 211 is opened. After the juice passes through the check valve 211, it is blocked by the check valve 211 and cannot flow back, and finally flows back into the degassing tank 22 through the infusion tube 29 to complete the circulating flow. The circulating flow enables the degassed juice to be remixed with the non-degassed juice, diluting the gas and improving the degassing speed and efficiency. When the juice passes through the check valve 211, the float in the automatic exhaust valve 210 drops, and the juice drives the first impeller 33 to rotate when flowing through the first impeller 33. The first impeller 33 drives the first rotating shaft 38 to rotate, and the first rotating shaft 38 drives the liquid outlet rotary barrel 28 to rotate. When the notch opened on one side of the liquid outlet rotary barrel 28 rotates and aligns with the nozzle of the infusion tube 29, the juice flows out; otherwise, the juice cannot flow out, enabling the juice to intermittently flow into the infusion tube 29, ensuring that there is a period of hollow time in the infusion tube 29, facilitating the exhaust of the automatic exhaust valve 210, and thus further improving the degassing efficiency.

[0014] Please refer to Figures 5-6, on the basis of the above embodiments, in another embodiment of the present invention, it includes a filtering device 3. The filtering device 3 includes a sieving structure and a dynamic filtering structure. The sieving structure includes a water pump 31, a fluid propulsion chamber 32, a first impeller 33, a rising pipe 34, and a filter plate 35. The water pump 31 is fixedly connected below the L-shaped hose 26. The fluid propulsion chamber 32 is opened at the bottom of the liquid storage tank 27. The first impeller 33 is rotatably connected to the bottom surface of the fluid propulsion chamber 32. The bottom end of the rising pipe 34 is fixedly connected to the right side of the liquid storage tank 27. The filter plate 35 is slidably connected to the inner wall of the liquid storage tank 27. The fruit juice flows into the water pump 31 from the L-shaped hose 26. The water pump 31 pressurizes the fruit juice and sprays the fruit juice into the fluid propulsion chamber 32. After the fruit juice is sprayed into the fluid propulsion chamber 32, it impacts the blade surface of the first impeller 33, pushing it to rotate, and then flows into the rising pipe 34. When the fruit juice reaches the top of the rising pipe 34, it rushes into the liquid storage tank 27 due to gravity. When the fruit juice passes through the filter plate 35, the fruit residue will be filtered out by the filter plate 35, improving the taste. The dynamic filtering structure includes a compression spring 36, a first mounting plate 37, a first rotating shaft 38, and blades 39. The compression spring 36 is fixedly connected below the filter plate 35. The first mounting plate 37 is fixedly connected to the bottom end of the compression spring 36. The first rotating shaft 38 is fixedly connected to the top end of the first impeller 33. The blades 39 are fixedly connected to the surface of the first rotating shaft 38. The water pump 31 is fixedly connected to the left side of the liquid storage tank 27. The first mounting plate 37 is fixedly connected to the inner wall of the liquid storage tank 27. The first rotating shaft 38 passes through the top of the fluid propulsion chamber 32. The first rotating shaft 38 is fixedly connected to the inner side of the liquid outlet rotating barrel 28. The top end of the rising pipe 34 is fixedly connected to the top surface of the liquid storage tank 27. The fruit juice impacts the filter plate 35 and pushes the filter plate 35 to compress the compression spring 36. After the compression spring 36 is compressed, it rebounds, causing the filter plate 35 to vibrate. The vibration of the filter plate 35 enables the fruit juice to flow down quickly from the filter holes, and at the same time enables the fruit juice and the fruit residue to be separated more quickly, improving the filtering effect. The fruit juice flows through the filter plate 35 into the liquid outlet rotating barrel 28. The first rotating shaft 38 drives the liquid outlet rotating barrel 28 to rotate to generate centrifugal force, causing the small fruit residues that have not been filtered out in the fruit juice to precipitate downward. At the same time, when the first rotating shaft 38 rotates, it also drives the blades 39 to rotate. The blades 39 stir the fruit juice, expanding the gaps between the fruit juice molecules, making it easier for the small fruit residues to precipitate, further promoting the filtering effect, and improving the taste and processing quality of the fruit juice. When the small fruit residues precipitate to the bottom of the liquid outlet rotating barrel 28, the fruit juice will flow out from the notch opened on one side of the top of the liquid outlet rotating barrel 28. And only when the notch of the liquid outlet rotating barrel 28 aligns with the nozzle of the liquid delivery pipe 29 after rotating one circle can the fruit juice flow out, providing a certain time for precipitation to fully filter the fruit juice; Working principle: The fruit juice flows into the water pump 31 from the L-shaped hose 26. The water pump 31 pressurizes the fruit juice and sprays the fruit juice into the fluid propulsion chamber 32. After the fruit juice is sprayed into the fluid propulsion chamber 32, it impacts the blade surface of the first impeller 33, driving it to rotate, and then flows into the rising pipeline 34. After the fruit juice flows to the top of the rising pipeline 34, it rushes into the liquid storage tank 27 due to gravity. When the fruit juice passes through the filter plate 35, the fruit residues will be filtered out by the filter plate 35, improving the taste. The fruit juice impacts the filter plate 35 and pushes the filter plate 35 to compress the compression spring 36. After the compression spring 36 is compressed, it rebounds, causing the filter plate 35 to vibrate. The vibration of the filter plate 35 enables the fruit juice to flow down quickly from the filter holes, and at the same time enables the fruit juice and the fruit residues to be separated more quickly, improving the filtering effect. The fruit juice flows through the filter plate 35 into the liquid outlet rotating barrel 28. The first rotating shaft 38 drives the liquid outlet rotating barrel 28 to rotate to generate centrifugal force, causing the fine fruit residues that have not been filtered out in the fruit juice to precipitate downward. At the same time, when the first rotating shaft 38 rotates, it also drives the blade 39 to rotate. The blade 39 stirs the fruit juice, expanding the gaps between the fruit juice molecules, making it easier for the fine fruit residues to precipitate, further promoting the filtering effect and improving the taste and processing quality of the fruit juice. When the fine fruit residues precipitate to the bottom of the liquid outlet rotating barrel 28, the fruit juice will flow out from the notch opened on one side of the top of the liquid outlet rotating barrel 28. And only when the notch of the liquid outlet rotating barrel 28 aligns with the nozzle of the infusion pipe 29 after rotating one circle can the fruit juice flow out, providing a certain time for precipitation and enabling the fruit juice to be fully filtered.

The partition 41 is fixedly connected to the inner wall of the top of the degassing tank 22, the second impeller 42 is rotatably connected to the inner wall of the top of the degassing tank 22, the liquid outlet 43 is opened on the inner side of the partition 41, the second rotating shaft 44 is fixedly connected to the bottom of the second impeller 42, the stirring paddle 45 is fixedly connected to the surface of the second rotating shaft 44, the water pump 31 pushes the juice to flow continuously, when the juice flows back into the degassing tank 22 from the infusion pipe 29, it will be blocked by the partition 41 and flow on the top of the degassing tank 22, at this time the flowing juice pushes the second impeller 42 to rotate The second impeller 42 drives the second rotating shaft 44 to rotate, and the second rotating shaft 44 drives the stirring paddle 45 to rotate. The stirring paddle 45 stirs the juice in the degassing tank 22. Because the gas has a lower density than the juice, the gas in the juice is in an ascending state. Therefore, after the juice is muddied, the gas inside is subject to reduced resistance from the juice, and rises faster, which helps to degas faster. The homogenizing structure includes a paddle 46, a second mounting plate 47, a homogenizing impeller 48, and a paddle wheel 49. The paddle 46 is fixedly connected to the surface of the second rotating shaft 44, the second mounting plate 47 is fixedly connected to the inner wall of the bottom of the degassing tank 22, the homogenizing impeller 48 is rotatably connected to the upper surface of the second mounting plate 47, the paddle wheel 49 is fixedly connected to the middle of the homogenizing impeller 48, and the second impeller 42 rotates through the lower surface of the partition 41. The homogenizing impeller 48 is rotatably connected to the lower surface of the partition 41, a bump is protruded on the surface of the toggle wheel 49 and the toggle plate 46 is transmission-connected to the bump, the stirring paddle 45 rotates at the center of the degassing tank 22, the juice around the degassing tank 22 is weakly stressed, and the rising speed of the gas around is inconsistent with the center, so a homogenizing impeller 48 is arranged around the degassing tank 22, when the second rotating shaft 44 rotates, it drives the toggle plate 46 to rotate, and the dial plate hits the toggle wheel 49 when it rotates, so that the toggle wheel 49 rotates, and the toggle wheel 49 drives the homogenizing impeller 48 to rotate, and the homogenizing impeller 48 stirs the juice around the degassing tank 22, so that the rising speed of the gas around is accelerated, which further promotes the degassing efficiency, makes the juice degassing more uniform, and has better production quality. The bottom of the second rotating shaft 44 is provided with a liquid outlet device 5 The liquid outlet device 5 includes a pushing structure and a rotating structure. The pushing structure includes a cam 51, a pushing member 52, and a scraper 53. The cam 51 is movably connected to the surface of the second rotating shaft 44, the pushing member 52 is slidably connected to the lower surface of the cam 51, and the scraper 53 is fixedly connected to the bottom end of the pushing member 52. During the degassing process of the juice, the valve in the liquid outlet cylinder below the degassing tank 22 is closed to prevent the juice from flowing out during the degassing process. However, some fruit residues will settle down inside the degassing tank 22 and block the liquid outlet cylinder, so a scraper 53 is arranged above the liquid outlet cylinder. When the second rotating shaft 44 rotates, the pushing member 52 is driven to rotate. When the pushing member 52 rotates, it touches the arc surface of the cam 51 and extends out. After the pushing member 52 extends out, it squeezes the reset spring 57, and the reset spring 57 drives the pushing member 52 to reset and retract.The pusher 52 is extended and retracted, and the extension and retraction of the pusher 52 drives the scraper 53 to extend and retract, and the extension and retraction of the scraper 53 scrapes off the fruit residue adhering to the inner wall of the liquid discharge cylinder, thereby improving the liquid discharge speed and accelerating the production efficiency. The rotating structure includes a connecting rod 54, a through groove 55, a pressure block 56, and a return spring 57. The connecting rod 54 is fixedly connected to both sides of the cam 51, and the through groove 55 is arranged on both sides of the bottom end of the second rotating shaft 44. The pressure block 56 is fixedly connected to the inner side of the pusher 52, and the return spring 57 is fixedly connected to the inner wall of the bottom end of the through groove 55. The connecting rod 54 is fixedly connected to the inner wall of the bottom of the degassing tank 22 Then, the pusher 52 is sleeved with the bottom surface of the second rotating shaft 44, the pressure block 56 is slidably connected with the inner side of the through groove 55, the bottom plate 1 of the pressure block 56 is fixedly connected with the top of the return spring 57, the bottom end of the degassing tank 22 is fixedly connected with the liquid discharge cylinder and the scraper 53 is slidably connected with the inner wall of the liquid discharge cylinder, and the pressure block 56 inside the pusher 52 is slidably connected in the through groove 55, which ensures that the scraper 53 can be telescopically rotated at the same time. The telescopic rotation of the scraper 53 increases the friction force when it contacts the inner wall of the liquid discharge cylinder, so that the scraping effect is better, further preventing the discharge cylinder from being blocked and improving the liquid discharge speed; Working principle: The water pump 31 pushes the juice to flow continuously. When the juice flows back into the degassing tank 22 from the infusion tube 29, it will be blocked by the partition 41 and flow to the top of the degassing tank 22. At this time, the flowing juice pushes the second impeller 42 to rotate, and the second impeller 42 drives the second rotating shaft 44 to rotate. The second rotating shaft 44 then drives the stirring paddle 45 to rotate. The stirring paddle 45 stirs the juice in the degassing tank 22. Because the gas has a lower density than the juice, the gas in the juice is in an ascending state. Therefore, after the juice is stirred, the gas inside is subject to less resistance from the juice, and rises faster, which helps to make the juice flow faster. Degassing, the stirring paddle 45 rotates at the center of the degassing tank 22. The juice around the degassing tank 22 is weakly stressed, and the rising speed of the gas around it is inconsistent with that at the center. Therefore, a homogenizing impeller 48 is arranged around the degassing tank 22. When the second rotating shaft 44 rotates, it drives the dial plate 46 to rotate. When the dial plate rotates, it hits the dial wheel 49, so that the dial wheel 49 rotates. The dial wheel 49 drives the homogenizing impeller 48 to rotate. The homogenizing impeller 48 stirs the juice around the degassing tank 22, so that the rising speed of the gas around it is accelerated, which further promotes the degassing efficiency, makes the juice degassing more uniform, and has better production quality. During the juice degassing process, the valve in the liquid outlet cylinder below the degassing tank 22 is closed to prevent the juice from flowing out during degassing. However, some fruit residues will precipitate downward inside the degassing tank 22 and block the liquid outlet cylinder. Therefore, a scraper 53 is provided above the liquid outlet cylinder. When the second rotating shaft 44 rotates, it drives the pushing member 52 to rotate. When the pushing member 52 rotates, it touches the arc surface of the cam 51 and extends. After the pushing member 52 extends, it compresses the return spring 57, and the return spring 57 drives the pushing member 52 to retract and reset, so that the pushing member 52 expands and contracts. The expansion and contraction of the pushing member 52 drives the expansion and contraction of the scraper 53, and the expansion and contraction of the scraper 53 scrapes off the fruit residues adhering to the inner wall of the liquid outlet cylinder, improving the liquid outlet speed, accelerating the production efficiency. Moreover, the pressing block 56 inside the pushing member 52 is slidably connected in the through groove 55, ensuring that the scraper 53 expands, contracts and rotates simultaneously. When the scraper 53 expands, contracts and rotates, the contact with the inner wall of the liquid outlet cylinder increases the friction force, making the scraping effect better, further preventing the discharge cylinder from being blocked, and improving the liquid outlet speed.
