Description

Technical Field

[0001] This utility model belongs to the field of juice processing technology, and specifically relates to a pressing device for producing Wogan mandarin orange juice. Background Technology

[0002] Wogan tangerines are rich in nutrients such as vitamin C and flavonoids, and the juice made from them is delicious and nutritious, making it a favorite among consumers. With the increasing market demand for Wogan tangerine juice, the Wogan tangerine juicing industry has developed rapidly. Currently, there are various Wogan tangerine juicing equipment available on the market, ranging from traditional manual juicing tools to automated large-scale juicing production lines, meeting the needs of production at different scales.

[0003] Traditional manual juicing methods are inefficient, labor-intensive, and yield low juice output, making them unsuitable for large-scale production. While existing automated juicing equipment has improved efficiency to some extent, it still has many shortcomings. For example, most existing citrus juicing equipment requires crushing the fruit before squeezing out the juice. This method has the advantage of high juice yield, but the disadvantages include more impurities in the juice, and even after filtration, it cannot remove fine pulp, resulting in a sticky aftertaste. Furthermore, due to the high pulp content, the juice often tastes slightly bitter and lacks sweetness.

[0004] To avoid the above defects, another type of juicing equipment has appeared on the market, such as the patent application number CN202020743386.6, "A Juicing Device for Navel Orange Processing". The patent document describes: This utility model discloses a juicing device for navel orange processing, including a squeezing head and a juicing box. A cylinder is mounted on a first support. A connecting plate is provided at the lower end of the telescopic rod of the cylinder. A fixing rod is provided at the lower end of the connecting plate. A squeezing head is provided at the lower end of the fixing rod. Spiked protrusions are provided on the outer wall surface of the squeezing head. A placement plate is fixedly mounted on the juicing box. A filter tank is provided on the placement plate. A filter residue plate is provided inside the juicing box. A residue storage tank is provided on the filter residue plate. A liquid guide pipe is provided at the lower end of the juicing box. A juice storage box is provided below the liquid guide pipe. The upper end of the second support is fixedly connected to the liquid guide pipe. This device allows for the simultaneous juicing of multiple navel oranges, and the multiple pointed protrusions greatly improve juicing efficiency. It also makes the placement plate easy to disassemble, allowing for further filtration of small particulate impurities mixed in the juice, thus greatly ensuring the purity of the juice.

[0005] This type of juicing equipment abandons the traditional method of crushing fruit pulp and then squeezing out the juice. Instead, it uses whole fruit to squeeze out the juice, which can maintain the high quality of the juice. However, in actual use, this type of juicing equipment also has some drawbacks. For example, only one fruit can be placed in each filter tank, resulting in low juicing efficiency. Furthermore, the spikes on the squeeze head can cause gaps to form between the squeeze head and the filter tank, leading to low fruit pulp juicing efficiency. Utility Model Content

[0006] This utility model aims to provide a pressing device for producing Wogan mandarin orange juice, mainly to solve the technical problems of existing equipment where only one fruit can be placed in a filter tank, resulting in low juicing efficiency, and the sharp points on the extrusion head causing gaps between the extrusion head and the filter tank, leading to low pulp juicing efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A pressing device for producing Wogan mandarin orange juice includes a protective shell, a receiving device disposed on the protective shell, and a pressing device that can be pressed down toward the receiving device. The receiving device includes a receiving plate with a downwardly recessed receiving cavity capable of holding multiple Wogan mandarins at once. The pressing device includes a pressing column whose surface mates with the inner wall of the receiving cavity. The receiving plate has a plurality of juice outlet holes, and the pressing column has a plurality of guide needles that can be inserted into the juice outlet holes.

[0009] The beneficial effects of this plan are:

[0010] In operation, the washed and peeled Wogan tangerines are first transported to the receiving chamber of the receiving device via a conveying mechanism. Then, the pressing column of the pressing device presses down to squeeze out the juice from the tangerines. During the pressing process, the guide needles on the pressing column first contact, pierce, and pass through the tangerines, and then the surface of the pressing column contacts and squeezes the tangerines, which can improve the juice extraction efficiency. Furthermore, compared to existing juicing equipment, this device also uses compression juicing, and the receiving chamber can hold multiple tangerines at a time, resulting in a larger juice output per batch than existing juicing equipment. Additionally, the guide needles on the pressing column in this solution can pass through the juice outlet, allowing the pressing column to fit tightly against the inner wall of the receiving chamber, preventing gaps that could lead to incomplete fruit extraction. In summary, this solution solves the technical problems of existing equipment, where only one fruit can be placed in each filter tank, resulting in low juicing efficiency, and the sharp points on the pressing head causing gaps between the pressing head and the filter tank, leading to low juice extraction efficiency.

[0011] Preferably, the bottom wall of the receiving cavity is a semi-cylindrical arc surface, and the surface of the pressing column is cylindrical to match the shape of the bottom wall of the receiving cavity. The juice outlet holes correspond one-to-one with the guide needles, and their centerlines are vertically arranged. In this design, as the guide needles pass through the Wogan mandarin orange from top to bottom and the pressing column presses down on the Wogan mandarin orange, the pulp can be split and then squeezed by several guide needles, making the Wogan mandarin orange more fluffy inside during the juicing process and resulting in a higher juice yield.

[0012] Preferably, the diameter of the guide needle gradually decreases from the end closer to the pressing column to the end farther away from the pressing column. In this design, the guide needle is generally conical, which makes it easier to pierce the Wogan mandarin orange and has a better splitting effect on the fruit.

[0013] Preferably, the receiving device further includes a mounting frame fixed to the protective shell, the mounting frame having an installation opening, the receiving plate being disposed within the installation opening and rotatably connected to the mounting frame, and the mounting frame also having a driving device for intermittently rotating the receiving plate; a fruit pomace collection bucket is disposed below the rear of the mounting frame; and a juice collection bucket is disposed below the receiving plate and inside the protective shell. In this design, after the Wogan mandarin orange juice is pressed, the driving device drives the receiving plate to rotate, turning the fruit pomace into the fruit pomace collection bucket behind it, and then rotating it back to its original position for the next pressing.

[0014] Preferably, the bottom of the fruit pomace collection bucket has several percolation holes, and a flow guide box is installed at the bottom of the fruit pomace collection bucket. The flow guide box is open on one side, and the bottom of the flow guide box extends into the juice collection bucket at the open end. In this solution, the remaining juice in the fruit pomace will enter the flow guide box through the percolation holes and then enter the juice collection bucket, thereby improving the juice yield.

[0015] Preferably, a limiting baffle is fixed to the upper surface of the receiving tray. In this design, the limiting baffle ensures that the receiving tray is stably placed on the mounting frame after being flipped over, and that the receiving tray can withstand greater pressure when the pressing column presses down.

[0016] Preferably, the driving device includes a rotating shaft and two fixing blocks fixed on the mounting frame at both ends of one side of the receiving plate. Each fixing block has a coaxially arranged shaft hole. The rotating shaft passes through the shaft hole and can rotate relative to it. A motor is fixed to one end of the rotating shaft. One side of the receiving plate is fixed to the rotating shaft. In this design, when the motor rotates, it drives the rotating shaft to rotate, thereby causing the receiving plate to flip. Simultaneously, the motor can rotate forward and reverse. The frequency and angle of forward and reverse rotation can be adjusted according to production conditions to control the receiving plate to cooperate with the pressing device for juicing and removing fruit residue.

[0017] Preferably, the device also includes a conveyor belt for intermittently conveying Wogan oranges to the receiving tray. In this embodiment, after the Wogan orange pulp on the receiving device is cleaned, the conveyor belt starts moving, conveying the Wogan oranges to the receiving tray. When the receiving tray has enough Wogan oranges, the conveyor belt stops conveying. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0029] like Figure 1 , Figure 2 As shown, the pressing equipment for producing Wogan mandarin orange juice involved in this embodiment is a comprehensive device that integrates multiple functions such as receiving, pressing, conveying, and pomace treatment. It is located in the juice pressing stage of the Wogan mandarin orange juice production line, and the pressing equipment for producing Wogan mandarin orange juice is set inside the frame (the frame part is not shown in the figure). It mainly consists of two core parts: a receiving device and a pressing device. Each part cooperates with the others to achieve an efficient Wogan mandarin orange juice pressing process. The pressing equipment for producing Wogan mandarin orange juice also includes a protective shell 7. The receiving device is installed on the protective shell 7, while the pressing device is installed on the frame.

[0030] like Figure 3 , Figure 4 As shown, the receiving device is the basic load-bearing structure of the entire equipment, and its core component is the receiving tray 2. The receiving tray 2 is made of high-strength food-grade stainless steel, which has good corrosion resistance and hygiene properties, ensuring that the product will not be contaminated during the juice production process. The receiving tray 2 has a downwardly recessed receiving cavity, and the bottom of the receiving cavity has a unique semi-cylindrical arc surface, allowing tangerines to be placed in the receiving cavity in batches.

[0031] The pressing device is the key component for juicing Wogan oranges. It includes a liquid cylinder mounted on a frame, a movable frame 4 that moves up and down under the drive of the liquid cylinder, and a pressing column 41 fixed to the lower part of the movable frame 4. The pressing column 41 is cylindrical in shape, matching the receiving cavity, and is made of stainless steel with a finely polished surface to ensure a tight fit with the inner wall of the receiving cavity. Several guide needles 42 are regularly distributed on the surface of the pressing column 41; these guide needles 42 are important components for achieving efficient juicing.

[0032] Meanwhile, a number of juice outlet holes 21 are evenly opened around the surface on the bottom wall of the receiving cavity. The guide needle 42 corresponds to the juice outlet hole 21 and can be inserted into the juice outlet hole 21. The axis of the guide needle 42 and the juice outlet hole 21 are both vertically arranged.

[0033] Below the receiving tray 2 is a juice collection bucket 8, which is used to collect the juice after pressing.

[0034] Once the Wogan mandarin orange is accurately placed in the receiving chamber, the pressing device is activated. The pressing column 41 moves slowly and smoothly downwards, applying pressure to the Wogan mandarin orange. During this process, the guide needles 42 on the pressing column 41 first come into contact with the Wogan mandarin orange, directly penetrating the pulp to create a channel for the juice to flow out. At the same time, this further disrupts the internal structure of the Wogan mandarin orange, making the inside more fluffy. Then, the surface of the pressing column 41 contacts and squeezes the Wogan mandarin orange, causing the juice to flow out of the receiving chamber through the juice outlet 21.

[0035] This unique pressing method avoids the traditional pulverizing juicing method, preserving the juice's flavor. It also offers significant advantages over traditional single-squeezing methods. Traditional squeezing methods often only apply pressure to the surface of the tangerine, failing to fully break down the internal structure of the pulp, resulting in incomplete juice extraction. This equipment, however, significantly increases the juice yield of the tangerine through the internal splitting of the guide needle 42 and the uniform squeezing of the pressing column 41.

[0036] The design of the guide needle 42 is one of the core innovations of this equipment. The guide needle 42 is conical in shape, an optimization based on principles of fluid mechanics and materials mechanics, offering numerous advantages. In terms of penetration performance, the conical guide needle 42, with its sharp tip, can easily pierce the peel of the Wogan mandarin orange under relatively low pressure. Regarding pulp splitting, after the conical guide needle 42 inserts into the Wogan mandarin orange pulp, as the pressing column 41 presses down, it creates a gradually expanding space within the pulp. This space causes the pulp to spread outwards under pressure, making it easier to split into multiple small pieces. This splitting effect not only helps increase the juice yield but also makes the pulp particles in the juice smaller and more uniform, improving the taste and quality of the juice.

[0037] like Figure 4As shown, to achieve an efficient production process, the receiving device also has the functions of automatic flipping and fruit pomace collection. The receiving tray 2 is rotatably installed in the mounting port on the mounting frame 1. The mounting frame 1 is equipped with a drive device that drives the receiving tray 2 to flip intermittently. The drive device consists of two fixed blocks 33 fixed on the mounting frame 1 and located at both ends of one side of the receiving tray 2, a rotating shaft 32, and a servo motor 31. Each fixed block 33 has a coaxial shaft hole. The rotating shaft 32 passes through these shaft holes and can rotate freely relative to the shaft holes. The rotating shaft 32 is fixed to one side of the receiving tray 2, and the servo motor 31 serves as the drive source. Its output end is fixed to the rotating shaft 32, providing precise power control for the flipping of the receiving tray 2. A fruit pomace collection bucket 6 is installed behind the mounting frame 1. Figure 5 As shown, the bottom of the fruit pomace collection bucket 6 is provided with several percolation holes, and a flow guide box 9 is installed at the bottom of the fruit pomace collection bucket 6. The flow guide box 9 is open on one side, and the bottom of the flow guide box 9 extends into the juice collection bucket 8 at the open end. The remaining juice in the fruit pomace will enter the flow guide box 9 through the percolation holes and then enter the juice collection bucket 8, thereby improving the juice yield.

[0038] After the Wogan mandarin orange juice is fully pressed, the motor 31 drives the receiving plate 2 to slowly rotate 180° via the rotating shaft 32, allowing the pulp in the receiving plate 2 to be smoothly poured into the pulp collection bucket 6 placed below the mounting frame 1. After the pulp is poured out, the servo motor 31 drives the receiving plate 2 to rotate back to its original position, ready for the next juicing operation. By precisely controlling the forward and reverse rotation speed and angle of the servo motor 31, the rotation action of the receiving plate 2 can be flexibly adjusted according to different production needs and rhythms, ensuring efficient and stable operation of the entire juicing process. For example, in large-scale production, the rotation speed can be appropriately increased to reduce the production cycle; while when higher juice quality is required, the rotation speed can be appropriately reduced to ensure thorough pulp removal.

[0039] Limiting baffles 22 are fixedly installed on both sides of the receiving tray 2. When the receiving tray 2 is flipped over, the limiting baffles overlap the upper surface of the mounting frame 1, ensuring that the receiving tray 2 is stably placed on the mounting frame 1 and preventing the receiving tray 2 from shaking or shifting during placement. At the same time, during the process of pressing the pressing column 41 to extract juice from the Wogan oranges, the limiting baffles 22 can play a role in buffering and supporting, enhancing the structural strength of the receiving tray 2 and enabling it to withstand greater pressure.

[0040] In addition, this equipment is also equipped with a conveyor belt 5 for intermittently conveying Wogan oranges to the receiving tray 2. After the Wogan orange pulp on the receiving device is cleaned up, the conveyor belt 5 conveys the washed and peeled Wogan oranges in batches to the receiving tray 2 at a stable speed.

[0041] The device also includes a controller and a weight sensor that are electrically connected to each other. The servo motor 31 and the drive motor 31 in the conveyor belt 5 are all electrically connected to the controller.

[0042] A rubber sheet is provided on the lower surface of the limiting plate. The weight sensor is located on the mounting frame 1 below the rubber sheet. The sensor transmits the signal to the controller by sensing the weight of the receiving plate 2. After analysis, the controller determines whether the pulp in the receiving plate 2 is full, not juiced, or juiced. The controller then controls the conveyor belt 5 to convey the pulp into the receiving plate 2 until the preset weight is reached and stops, or controls the servo motor 31 to start according to the preset program. After juicing, the servo motor 31 drives the receiving plate 2 to flip and pour out the pulp.
