Description

Technical Field

[0001] This invention relates to the field of beverage filling technology, specifically to a rotary plunger type large-particle fruit pulp filling equipment. Background Technology

[0002] With societal development, bottling equipment and technology for fruit pulp beverages are constantly innovating. Adding fruit pieces to fruit pulp beverages not only enhances their appearance but also enriches their taste and flavor, and improves their nutritional value, thus making them more appealing to consumers.

[0003] CIP cleaning, or Clean in Place, is a safe and automated cleaning system that does not break down production equipment and can be operated safely. It has been adopted in almost all food, beverage, and pharmaceutical factories. CIP cleaning not only cleans machines but also controls microorganisms.

[0004] Current fruit pulp beverage bottling processes typically involve first mixing fruit pulp and fruit particles, then filling the resulting beverage into bottles using a bottling machine. However, fruit particles and pulp tend to settle within the bottling machine, resulting in varying fruit particle content in each bottle. Large fruit particles can also clog the filling nozzles, rendering the machine unusable. Furthermore, the difficulty in cleaning the internal components of the bottling machine leads to equipment contamination if sediment and blockages are not completely removed over time. Conventional mixing devices can also damage the integrity of the fruit particles during mixing, negatively impacting the consumer's drinking experience. Therefore, improvements to the bottling equipment and cleaning system for large-particle fruit pulp are necessary. Summary of the Invention

[0044] like Figures 1 to 7 As shown, this invention discloses a rotary plunger-type large-particle fruit pulp filling device, including a rotary bottle feeding device 7, a fruit pulp tank 1, a stirring device, a filling assembly, and a cleaning assembly 5. The rotary bottle feeding device 7 includes a drive assembly 71, a rotating base 72, and a bottle feeding mechanism 73. The drive assembly 71 drives the rotating base 72 to rotate.

[0045] The filling assembly includes a plunger cylinder 2, a filling valve 3, and a three-way valve 4. The three-way valve 4 is connected to the pulp tank 1, the plunger cylinder 2, and the filling valve 3, respectively. Multiple filling assemblies are arranged in a circumferential array around the periphery of the pulp tank 1. The filling valve 3 is located above the conveying path of the bottle feeding mechanism 73, and the filling valve 3 rotates synchronously with the bottle feeding mechanism 73.

[0046] The cleaning assembly 5 includes an inlet pipe 51, a valve assembly, and a drain pipe 57. The inlet pipe 51 is connected to the plunger cylinder 2, the filling valve 3, and the pulp tank 1 through the valve assembly, and is used to clean the inside of the plunger cylinder 2, the filling valve 3, the pulp tank 1, and the interconnected pipes. The waste liquid after cleaning is discharged through the drain pipe 57 connected to the pulp tank 1.

[0047] Understandably, in this embodiment, the three-way valve 4 cooperates with the plunger cylinder 2 to enable the plunger cylinder 2 to extract and inject large-particle fruit pulp. By placing the filling valve 3 above the conveying path of the bottle feeding mechanism 73, and keeping the filling valve 3 and the bottle feeding mechanism 73 rotating synchronously, the function of multiple filling valves 3 filling simultaneously can be realized. The conveying path of the bottle feeding mechanism 73 is located on the periphery of the rotating base 72, and the conveying direction of the bottle feeding mechanism 73 is the same as the rotation direction of the rotating base 72, which enables the rotating conveying of beverage bottles. The cleaning component 5 can clean the plunger cylinder 2, the filling valve 3, the inside of the fruit pulp tank 1, and the interconnected pipes.

[0048] Continue to refer to Figure 3 In this embodiment, the bottle feeding mechanism 73 includes an inlet wheel assembly 731, an outlet wheel assembly 732, and a rotating conveyor belt 733. The rotating conveyor belt 733 is located around the periphery of the rotating base 72. The filling valve 3 is located above the rotating conveyor belt 733 and rotates synchronously with the rotating conveyor belt 733. The inlet wheel assembly 731 is located to the lower right of the rotating conveyor belt 733, and the outlet wheel assembly 732 is located to the lower left of the rotating conveyor belt 733. The inlet wheel assembly 731 and the outlet wheel assembly 732 rotate in the same direction, but in the opposite direction to the rotating conveyor belt 733. Furthermore, the bottle feeding mechanism 73 also includes a drip tray 734, which is located between the inlet wheel assembly 731 and the outlet wheel assembly 732, and is used to collect the fruit pulp dripping from the filling valve 3. Preferably, the bottle inlet wheel assembly 731 and the bottle outlet wheel assembly 732 have the same structure and size. The bottle inlet wheel assembly 731 is used to feed the beverage bottles to be filled into the rotating conveyor belt 733, and the bottle outlet wheel assembly 732 is used to guide the filled beverage bottles from the rotating conveyor belt 733 to the outside.

[0049] Continue to participate Figure 1 and Figure 2In this embodiment, the pulp tank 1 includes a tank body 11 and a first discharge port 12. Multiple first discharge ports 12 are arranged in a circumferential array around the periphery of the tank body 11, and each first discharge port 12 is connected to a filling assembly. Further, the stirring device includes a first drive mechanism 13 and a stirring structure 14. The stirring structure 14 is rotatably disposed within the tank body 11, and the first drive mechanism 13 drives the stirring structure 14 to rotate. Specifically, the stirring structure 14 includes a rotating shaft 141 and stirring blades 142. The rotating shaft 141 is horizontally disposed within the tank body 11, with one end connected to the inner wall of the tank body 11 and the other end penetrating the tank body 11 and connected to the first drive mechanism 13. An mounting sleeve and a sealing assembly are provided on the side wall of the tank body 11. The mounting sleeve is fixedly connected to both ends of the rotating shaft 141 inside the tank body 11, and the sealing assembly ensures the airtightness between the tank body 11 and the rotating shaft 141, preventing pulp leakage from the side wall of the tank body 11. In addition, the stirring blade 142 is set in the shape of an angled scraper, and the two stirring blades 142 are arranged far apart on the rotating shaft 141. The first driving mechanism 13 is preferably a geared motor, which can drive the stirring structure 14 to stir and mix the fruit pulp and fruit particles in the tank 11, and avoid damaging the integrity of the fruit particles, and also improve the cleaning efficiency inside the tank 11 to avoid particle sedimentation.

[0050] Continue to refer to Figure 4 In this embodiment, the plunger cylinder 2 includes a cylinder barrel 21 and a plunger 22, a guide rod 23, a second drive mechanism 24, a second discharge port 25, and a water inlet 26. The cylinder barrel 21 has an upper cylinder barrel 211 and a lower cylinder barrel 212 that are connected to each other. The inner diameter of the upper cylinder barrel 211 is larger than the inner diameter of the lower cylinder barrel 212. The water inlet 26 is located at the top of the upper cylinder barrel 211. The lower cylinder barrel 212 is adapted to the plunger 22. The plunger 22 is slidably connected to the inner wall of the lower cylinder barrel 212.

One end of the guide rod 23 is fixedly connected to the plunger 22, and the other end passes through the top of the upper cylinder barrel 211 and is connected to the second drive mechanism 24. The second drive mechanism 24 is used to drive the plunger 22 to move up and down inside the cylinder barrel 21. It is worth noting that the lower cylinder 212 works in conjunction with the plunger 22 to extract and inject large-particle fruit pulp. When the plunger 22 moves to the middle of the upper cylinder 211, the upper cylinder 211 works in conjunction with the water inlet 213 to thoroughly clean the interior of the plunger 22 and the cylinder 21.

[0051] Continue to refer to Figure 5In this embodiment, the filling valve 3 includes a third inlet 31, a third outlet 32, a valve sleeve 33 and a valve core 34 that are adapted to each other, and a third driving mechanism 35.

The third inlet 31 is located above the side wall of the valve sleeve 33, and the third outlet 32 ​​is located at the bottom of the valve sleeve 33. Preferably, the bottom end of the valve core 34 is conical, so that when the bottom end of the valve core 34 moves to the third outlet 32, it can push out any blockage in the third outlet 32. It is worth noting that, in its initial state, the valve core 34 is located at the bottom end of the valve sleeve 33 and closes the third outlet 32. When the bottom of the third outlet 32 ​​aligns with the beverage bottle to be filled, the valve core 34 moves to the top within the valve sleeve 33, connecting the third inlet 31 with the third outlet 32. The plunger cylinder 2 can then inject large-particle fruit pulp from the cylinder 21 into the filling valve 3, and through the filling valve 3, into the beverage bottle to be filled. Additionally, a bottle clamping mechanism 6 is included, located below the third outlet 32, for clamping and fixing the beverage bottle to be filled.

[0052] Continue to refer to Figure 6 In this embodiment, the three-way valve 4 includes a valve body 41, a piston 42, and a fourth drive mechanism 43. The fourth drive mechanism 43 is used to drive the piston 42 to move horizontally within the valve body 41. When the piston 42 moves horizontally to one end of the valve body 41, the first outlet 12 is connected to the second outlet 25, and the third inlet 31 is closed, so that the plunger cylinder 2 can draw large-particle fruit pulp from the fruit pulp tank 1 into the cylinder 21. When the piston 42 moves horizontally to the other end of the valve body 41, the second outlet 25 is connected to the third inlet 32, and the first outlet 12 is closed, so that the plunger cylinder 2 can inject large-particle fruit pulp from the cylinder 21 into the filling valve 3.

The rotating spray structure 55 is located below the top wall of the tank body 11 and can perform all-round cleaning of the inside of the tank body 11.

[0055] Understandably, the second cleaning circuit can perform deep cleaning of the filling valve 3 and the three-way valve 4, and preliminary cleaning of the plunger cylinder 2. The first cleaning circuit can perform deep cleaning of the plunger cylinder 2 and the three-way valve 4. The third cleaning circuit can perform deep cleaning of the inner wall of the tank 11. Through the combined use of the above cleaning circuits, the CIP cleaning function of the large particle fruit pulp filling equipment can be realized.

One end of the second valve assembly 53 is connected to the pulp tank 1, and the other end is connected to the upper annular cavity 522. When the first cleaning circuit is started, the cleaning fluid in the inlet pipe 51 enters the upper annular cavity 522 through the first valve 521, then enters the corresponding plunger cylinder 2 through the inlet 26, and then enters the tank body 11 through the three-way valve 4 before being discharged through the drain pipe 57.

[0057] Continue to refer to Figure 5 The third valve assembly 54 includes a third valve 541, a lower annular cavity 542, and a connecting element 543. One end of the third valve 541 is connected to the inlet pipe 51, and the other end is connected to the lower annular cavity 542. Each third outlet 32 ​​is movably connected to the upper port of a connecting element 543, and the lower port of the connecting element 543 is connected to the lower annular cavity 542 via a hose. When the second cleaning circuit is started, the cleaning fluid in the inlet pipe 51 enters the lower annular cavity 542 through the third valve 541, then enters the corresponding filling valve 3 through the third outlet 32 ​​connected to the connecting element 543, then enters the plunger cylinder 2 through the three-way valve 4, enters the upper annular cavity 522 through the water inlet 26, and finally enters the tank 11 through the second valve assembly 53 and is discharged through the drain pipe 57. Specifically, the bottle clamping mechanism 6 is located below the third discharge port 32 and is used to clamp and fix the guide 543 so that the guide 543 is in close communication with the third discharge port 32.

[0058] Preferably, the drainage pipe 57 is located at the middle of the bottom of the tank body 11, and the upper end of the drainage pipe 57 is rotatably connected to the tank body 11, while the lower end of the drainage pipe 57 is connected to the fruit pulp raw material tank and the washing liquid recovery tank respectively through valves.

[0059] In addition, the stirring blade 142 is set in the shape of an angled scraper, and the two stirring blades 142 are arranged far apart on the rotating shaft 141. The first driving mechanism 13 is preferably a geared motor, which can drive the stirring structure 14 to stir and mix the fruit pulp and fruit particles in the tank 11, and can also improve the cleaning efficiency inside the tank 11 and avoid particle sedimentation.

[0060] Furthermore, the pulp tank 1 also includes a pressure relief valve 15, which is located at the top of the tank body 11 and can release air and reduce pressure when the cleaning liquid gathers inside the tank body 11.

[0061] Furthermore, the pulp tank 1 also includes a liquid level sensor 16, which is located inside the tank body 11 and is used to monitor the liquid level in the tank body 11 in real time; the top of the tank body 11 is also provided with a brush ring 17, which is used to realize the electrical connection between the electrical equipment above the mounting base 72 and the external circuit.

[0062] This embodiment also includes a conventional control system consisting of a power supply circuit, a control circuit, an MCU, and a signal transceiver device; the specific structure is not described in detail. Furthermore, the valve assembly preferably uses a pneumatic butterfly valve, which is driven and controlled separately by an air compressor.

[0063] Therefore, the rotary plunger type large-particle fruit pulp filling equipment in this embodiment achieves the following functions:

[0064] (1) Extraction and injection functions

[0065] By setting a three-way valve connected to the first discharge port, the second discharge port, and the third inlet port respectively, the plunger cylinder can draw large-particle fruit pulp from the pulp tank into the cylinder, inject the large-particle fruit pulp from the cylinder into the filling valve, and then inject it into the beverage bottle to be filled through the filling valve. The three-way valve and the plunger cylinder work together to realize the function of the plunger cylinder to draw and push large-particle fruit pulp.

[0066] (2) Rotary conveyor function

[0067] By setting the conveying path of the bottle feeding mechanism on the periphery of the rotating base, and the conveying direction of the bottle feeding mechanism being the same as the rotation direction of the rotating base, the beverage bottles can be rotated and conveyed. The infeed wheel set is used to feed the beverage bottles to be filled into the rotating conveyor belt, and the outfeed wheel set is used to guide the filled beverage bottles from the rotating conveyor belt to the outside, which can save equipment installation space and has good rotational conveying function.

[0068] (3) Stirring and mixing function

[0069] By rotatably arranging the stirring structure inside the tank, and horizontally arranging the shaft of the stirring structure inside the tank, the first drive mechanism can drive the stirring structure to stir and mix the fruit pulp and fruit particles inside the tank, thus ensuring the uniformity of the particles in the fruit pulp inside the tank.

[0070] (4) CIP cleaning function
