A screw rod is movably connected to the inside of the uniform speed feeding box. The screw rod is composed of two parts: a first gap section and a second gap section. When the crushed fruits and vegetables are guided, the fruits and vegetables are initially pressed through the gradually decreasing gap, so that the pulp and juice are separated. In addition, the gradually decreasing gap can block air and improve the vacuum effect in the vacuum box. The first filter plate and the second filter plate are set in the discharge frame to facilitate the filtration of juice from the fruits and vegetables. Additionally, the crushing chamber is equipped with a first crushing roller and a second crushing roller that fit together, enabling effective crushing of fruits and vegetables when rotating in opposite directions.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-8 As shown, the present invention is a low-temperature crushing and fruit and vegetable juice extraction device.

[0021] Example 1 Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 In this invention, a technical solution is provided: a vacuum chamber 1, a vacuum pump 102 is installed on the upper left side of the vacuum chamber 1 for evacuating air from the vacuum chamber 1, a centrifugal filter frame 106 with solid-liquid separation function is provided on the inner side of the vacuum chamber 1, a compression conveying box 2 is installed on the upper end of the vacuum chamber 1, a uniform feeding box 203 is provided on the inner side of the compression conveying box 2, a collection box 202 is provided on the right side of the compression conveying box 2, a crushing processing box 3 is installed on the upper end of the compression conveying box 2, and a first crushing roller 305 and a second crushing roller 307 are respectively provided on the inner side of the crushing processing box 3 for crushing fruits and vegetables; An active gear disk 103 is installed on the lower left side of the vacuum chamber 1. A driven gear disk 104 is meshed with the right end of the active gear disk 103. The upper end of the driven gear disk 104 passes through the vacuum chamber 1 and is fixedly connected to the centrifugal filter frame 106. A fixed base block 105 connected to the centrifugal filter frame 106 is installed on the inner side of the vacuum chamber 1. The front end of the vacuum chamber 1 is fixedly connected to the first sealing panel 107 by bolts.

[0022] Furthermore, the centrifugal filter frame 106 forms a ring rotational motion on the fixed base block 105; A limiting groove 1061 is provided on the inner side of the centrifugal filter frame 106, and a guide port 1062 is provided on the inner side of the upper end of the centrifugal filter frame 106. A filter screen plate 1063 is provided on the inner side of the limiting groove 1061, and filter screen holes 1064 are opened on the inner side of the filter screen plate 1063.

[0023] Furthermore, the filter mesh 1064 is evenly opened on the inner side of the filter plate 1063, the filter plate 1063 is engaged with the centrifugal filter frame 106 through the limiting groove 1061, and the filter plate 1063 is threadedly connected to the centrifugal filter frame 106 through bolts. The outer side of the centrifugal filter frame 106 is provided with four equally divided slots.

[0024] Furthermore, a liquid inlet 108 is installed at the upper end of the vacuum chamber 1, and a one-way valve 1081 is provided at the lower end of the liquid inlet 108. A straight outlet pipe 1082 and a bellows pipe 1083 are sequentially provided at the lower end of the one-way valve 1081. The lower end of the straight outlet pipe 1082 passes through the inside of the guide port 1062 and extends downward.

[0025] Specifically, the entire device is first assembled, then the fruits and vegetables to be extracted are placed into the crushing and processing box 3. After being crushed in the crushing and processing box 3, the crushed fruits and vegetables enter the extrusion conveying box 2 for even discharge. Finally, a small amount of juice is discharged downwards from the liquid inlet 108. Since a one-way valve 1081 is installed at the lower end of the liquid inlet 108, and a straight outlet pipe 1082 and a bellows pipe 1083 are respectively set at the lower end of the one-way valve 1081, the lower part of the straight outlet pipe 1082 is nested in the guide port 1062, which not only can the straight outlet pipe 1082 be centered and limited, but also facilitates the discharge of materials. In addition, the filter screen plate 1063 is connected to the centrifugal filter frame 106 through the limiting groove 1061. When the filter screen plate 1063 is installed in the centrifugal filter... When the filter screen 106 is inside the filter frame 106, it can be threadedly connected to the centrifugal filter frame 106 using bolts, so that the filter screen 1063 is fixedly installed on the upper end of the centrifugal filter frame 106 to avoid shaking and displacement. The inner side of the centrifugal filter frame 106 has four equally divided slots, which facilitates the effective discharge of juice from the centrifugal filter frame 106. Finally, the juice can be discharged outward by opening the valve-type drain pipe 101. Alternatively, an external pipe can be installed on the outer end of the valve-type drain pipe 101. When the material enters the centrifugal filter frame 106, there are two separation operation methods: First, turn on the vacuum pump 102 to suck the air out of the vacuum chamber 1, so that the vacuum chamber 1 is in a vacuum state; Second, do not turn on the vacuum pump 102, so that the vacuum chamber 1 is in a normal temperature state.

[0026] The first method: Under vacuum conditions, the servo motor is turned on to rotate the active gear disk 103, causing the active gear disk 103 to drive the meshing driven gear disk 104 to rotate synchronously. Since the diameter of the active gear disk 103 is twice the diameter of the driven gear disk 104, the driven gear disk 104 can rotate faster under the uniform rotation of the active gear disk 103. By fixing the upper end of the driven gear disk 104 to the centrifugal filter frame 106, the centrifugal filter frame 106 can generate a corresponding rapid rotation. At this time, after the fruit and vegetable juice after preliminary filtration enters the centrifugal filter frame 106, with the rapid rotation of the centrifugal filter frame 106, the pulp adheres to the inner wall of the filter screen plate 1063, and the juice can be separated from the filter screen plate 1063 through the filter screen holes 1064 and stored in the vacuum chamber 1. In particular, vacuum conditions can effectively inhibit oxidative browning. The vacuum environment isolates oxygen, significantly reduces the activity of polyphenol oxidase, and prevents enzymatic browning of fruit and vegetable juices during separation, maintaining the natural color and clear appearance of the product. At the same time, vacuum conditions can protect heat-sensitive vitamins and natural aroma substances in fruits and vegetables from oxidative damage, maximizing the preservation of nutrients and flavor. It also improves juice yield and separation effect. The vacuum environment reduces the gas pressure between fruit and vegetable cells, making cell walls easier to break and juice easier to release. Under the action of centrifugal force, vacuum conditions can effectively reduce foam generation, making the separation of juice from pulp and pomace more thorough, increasing the juice yield by 5%-10%, and obtaining clearer juice. Furthermore, it reduces energy consumption and processing costs. Vacuum centrifugation can be carried out at lower temperatures (usually 0℃-4℃), reducing heating energy consumption and avoiding damage to product quality from high temperatures. The separated pomace has a lower water content, which facilitates subsequent drying and reduces transportation and storage costs. The second method: At room temperature, not only can the color and flavor be better preserved, but the juice yield can also be increased. At the same time, at room temperature and pressure, continuous production can be carried out. The centrifugal filter frame 106 can realize continuous feeding and continuous juice output. Compared with cold regions, using room temperature and pressure for pressing can relatively increase the temperature of the juice.

[0027] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 In this invention, a technical solution is provided: a second sealing panel 302 is provided at the front of the crushing and processing box 3 by bolts, and a rubber sealing strip 3021 is provided at the rear end of the second sealing panel 302 to engage with the crushing and processing box 3; The inner side of the second sealing panel 302 is also movably connected to a linkage mounting block 308 that is respectively engaged with the first crushing roller 305 and the second crushing roller 307; The rear end of the first crushing roller 305 is connected to the first gear disk 304, and the rear end of the second crushing roller 307 is connected to the second gear disk 306.

[0028] Furthermore, the first gear disk 304 is meshed with the second gear disk 306, and the front ends of the first gear disk 304 and the second gear disk 306 are each provided with a shaft block that engages with the first crushing roller 305 and the second crushing roller 307. The lower end of the crushing and processing box 3 is provided with a discharge frame 309, and the inner side of the discharge frame 309 is provided with a diversion block 3091 for diverting the crushed fruits and vegetables.

[0029] Specifically, in embodiment one, before extraction, fruits and vegetables need to be placed into the crushing and processing box 3 through the feed frame 301. The first crushing roller 305 and the second crushing roller 307 are respectively engaged with the second sealing panel 302 and the first gear disk 304 and the second gear disk 306 through the linkage mounting block 308 and the shaft block. When the servo motor is turned on to rotate the first gear disk 304, it drives the first crushing roller 305 to rotate synchronously. At this time, since the first gear disk 304 and the second gear disk 306 are meshed, the rotation direction of the first gear disk 304 is opposite to the rotation direction of the second gear disk 306, so that the rotation direction of the first crushing roller 305 and the second crushing roller 307 is opposite, thereby uniformly crushing the poured fruits and vegetables, and finally discharging them downward from the discharge frame 309. The crushing and processing box 3 is equipped with a second sealing panel 302 connected by bolts at the front end, and a rubber sealing strip 3021 that engages with the crushing and processing box 3 is provided at the rear edge of the second sealing panel 302. This ensures that the crushing and processing box 3 is sealed, preventing the leakage of fruit and vegetable juice and pulp. The detachable connection between the second sealing panel 302 and the crushing and processing box 3 facilitates the independent disassembly, maintenance, cleaning, or replacement of the first crushing roller 305 and the second crushing roller 307 in the later stages. A diverting block 3091 is installed at the inner end of the discharge frame 309. After the fruits and vegetables are crushed, they can be diverted and discharged under the action of the diverting block 3091. This setting not only improves the rapid discharge of crushed fruits and vegetables and avoids blockage, but also improves the uniform feeding of the subsequent extrusion conveyor box 2.

[0030] Example 3 This embodiment is derived based on Embodiment 1 and Embodiment 2. Please refer to [link / reference]. Figure 2 , Figure 4 , Figure 5 and Figure 6 In this invention, a technical solution is provided: the upper end of the uniform speed feeding box 203 is provided with a feeding port 2031, and the feeding port 2031 is symmetrically arranged about the center line of the uniform speed feeding box 203. A screw rod 2032 is provided on the inner side of the uniform speed feeding box 203; The screw rod 2032 is also provided with a first gap section 20321 and a second gap section 20322.

[0031] Furthermore, an extrusion port 2033 is provided on the inner side of one end of the uniform speed feeding box 203 for extruding fruit pomace. A discharge plate 201 located at the right end of the extrusion conveying box 2 is provided on one side of the extrusion port 2033 for guiding the extruded fruit pomace out.

[0032] Furthermore, a flow channel is provided on the inner side of the right end of the uniform speed feeding box 203, and a discharge frame 2034 connected to the uniform speed feeding box 203 is provided at the lower end of the flow channel. The inner side of the discharge frame 2034 is provided with a first filter plate 2035 and a second filter plate 2036 respectively; The lower inner side of the discharge frame 2034 is provided with a rubber ring that engages with the liquid inlet 108.

[0033] Specifically, in conjunction with Embodiment 1 and Embodiment 2, a rubber sealing block 303 is provided at the lower end of the crushing and processing box 3 to engage with and be installed with the extrusion conveying box 2. The extrusion conveying box 2 is connected to the crushing and processing box 3 by bolts and threads, which allows the crushed fruit and vegetable juice and pulp to fall evenly into the uniform feeding box 203 through the feed inlet 2031. A screw rod 2032 is movably connected inside the uniform feeding box 203. When the servo motor is turned on to rotate the screw rod 2032, the crushed fruit and vegetables can be stably conveyed to the right. A groove is provided on the lower right side of the uniform feeding box 203, which allows the juice to be initially filtered by the first filter plate 2035 and the second filter plate 2036 and then discharged downwards. The unfiltered pulp will be continuously pushed and squeezed out to the right from the extrusion port 2033, and finally discharged into the collection box 202 for unified collection along the discharge plate 201. The screw rod 2032 is configured with two parts: a first gap section 20321 and a second gap section 20322. As the gap between the first gap section 20321 and the second gap section 20322 decreases, it can perform progressive compression, allowing the pressure on the fruit and vegetable raw materials to gradually increase during transportation. This fully breaks down the cell walls, resulting in more thorough juice release and a significantly higher juice yield. Compared to the fixed-gap pressing method, progressive compression avoids the raw materials being subjected to excessive pressure at once, which could cause blockage or slippage, ensuring a smooth and continuous pressing process. Furthermore, the gradually decreasing gaps prevent excessive damage to the fruit and vegetable cells caused by instantaneous high pressure, reducing the excessive breakage of fruit pulp fibers that enter the juice. This results in higher clarity and less suspended matter in the extracted fruit and vegetable juice, while better preserving heat-sensitive vitamins and natural flavor substances. At the same time, progressive compression continuously compacts the raw materials during transportation, creating a "material blockage" effect. This effectively prevents material backflow and air ingress, improving equipment operational stability, reducing the number of shutdowns for cleaning, and preventing air ingress, which also helps maintain the vacuum environment within the vacuum chamber 1.

[0034] Example 4 This embodiment is derived based on Embodiment 1, Embodiment 2, and Embodiment 3. Please refer to [link / reference]. Figures 1-8 The present invention provides a technical solution, wherein the assembly method of the device includes the following steps: Step 1: First, place the filter screen 1063 into the centrifugal filter frame 106, and use the limiting groove 1061 to make the filter screen 1063 snap into the lower side of the centrifugal filter frame 106. Then, use bolts to thread the filter screen 1063 to the centrifugal filter frame 106, so that the centrifugal filter frame 106 and the filter screen 1063 form an integral structure. Step 2: Nest and engage the guide port 1062 on the inner side of the upper end of the centrifugal filter frame 106 with the lower end of the straight outlet tube 1082, so that the lower end of the straight outlet tube 1082 is located inside the guide port 1062 and extends downward. Then, place the entire centrifugal filter frame 106 on the fixed base block 105 to maintain the stability of rotation. Finally, connect the first sealing panel 107 to the vacuum chamber 1 with bolts. Step 3: At this time, place the extrusion conveyor box 2 on the upper end of the vacuum chamber 1, so that the lower end of the discharge frame 2034 is connected and engaged with the upper end of the liquid inlet 108 through the built-in rubber ring. Then, use bolts to thread the extrusion conveyor box 2 and the docking horizontal plate 109. Before this, the first filter plate 2035 and the second filter plate 2036 can be engaged and installed inside the discharge frame 2034. Finally, place the collection box 202 on the right end of the extrusion conveyor box 2, so that the left side of the collection box 202 is below the discharge plate 201. Step 4: Then, engage the first crushing roller 305 and the second crushing roller 307 with the linkage mounting block 308 and the shaft block respectively. Next, install the first crushing roller 305 and the second crushing roller 307 inside the crushing and processing box 3. After the second sealing panel 302 is installed with the crushing and processing box 3 through the rubber sealing strip 3021, the second sealing panel 302 is threadedly connected to the crushing and processing box 3 with bolts to complete the installation steps.
