Description

Technical Field

[0001] This utility model relates to the field of juicer technology, specifically a novel oxygen-free lemon juicer. Background Technology

[0002] Lemon juicers use high-speed rotation or squeezing devices to quickly separate lemon pulp, extracting smooth juice while filtering out pulp and retaining pure liquid. This efficiently releases nutrients such as vitamin C and citric acid from lemons, satisfying various needs such as direct consumption, beverage preparation, or cooking seasoning. Users can easily obtain fresh lemon juice and enhance their eating experience.

[0003] Patent document CN221355622U discloses an industrial lemon juicer. This document mainly considers the problems that juice and pulp are not easily separated during the juicing process, and that uneven feeding will lead to different pressures when the pulp is discharged during the juicing process, which will easily result in juice remaining in the pulp and causing waste. It also considers the problem that over-juicing will cause the pulp to be filtered along with the juice, affecting the quality of lemon juice. However, it does not consider the problems of incomplete separation of pulp and juice in traditional juicers, and the easy oxidation of juice when it comes into contact with air, which will lead to deterioration of taste and loss of nutrients. Utility Model Content

[0004] The purpose of this invention is to provide a novel oxygen-free lemon juicer to solve the problems mentioned in the background art, such as incomplete separation of pulp and juice in traditional juicers, easy oxidation of juice upon contact with air leading to deterioration in taste and loss of nutrients.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel oxygen-free lemon juicer, comprising a juicer body, wherein a centrifugal separation component is installed inside the juicer body, the centrifugal separation component being used to further separate the solid and liquid components of the initially extracted lemon juice and to delay the oxidation of the juice;

[0006] The centrifugal separation component includes a centrifugal chamber installed inside the juicer body. A servo motor is installed at the bottom of the centrifugal chamber. The output end of the servo motor is connected to a centrifugal basket, and the centrifugal basket is located inside the centrifugal chamber.

[0007] The bottom of the centrifuge chamber is connected to a first conveying pipe, the bottom of the first conveying pipe is connected to a conveying pump, and the bottom of the conveying pump is connected to a second conveying pipe.

[0008] Preferably, the juicer body is internally connected to a juicing cylinder, and the bottom of the juicing cylinder has evenly arranged leakage holes.

[0009] Preferably, a servo motor is installed inside the juicer body, and the output end of the servo motor is connected to a variable diameter screw shaft. The variable diameter screw shaft is located inside the juicing cylinder, and one end of the variable diameter screw shaft is connected to the side wall of the juicing cylinder.

[0010] The juicer body has a lemon juice storage compartment inside, which is located below the juicing cylinder and the servo motor.

[0011] Preferably, a residue discharge cylinder is connected to one side of the juicing cylinder, and one end of the residue discharge cylinder is located at the top of the centrifuge basket.

[0012] Preferably, the juicer body has a feed inlet at the top, which is located above the juicing cylinder, and a feed cover is provided at the top of the feed inlet.

[0013] Preferably, the juicer body is provided with a cleaning cover on top, and the cleaning cover is located above the centrifuge chamber.

[0014] Preferably, the bottom of the juicer body is provided with evenly distributed supports;

[0015] The juicer body has a liquid outlet pipe at the bottom, and a valve is installed at the bottom of the liquid outlet pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model constructs a centrifugal separation component inside the juicer body, consisting of a centrifugal chamber, a servo motor, a centrifugal basket, and a sealed conveying pipeline. The enclosed space of the centrifugal chamber reduces the contact area between the juice and air, and the centrifugal force generated by the high-speed rotation of the centrifugal basket performs deep solid-liquid separation of the virgin juice. At the same time, the closed-loop system of the conveying pump and pipeline achieves sealed transmission of the juice. Compared with the open separation or simple filter structure in the prior art, it can effectively separate the pulp particles in the juice, improve the light transmittance of the juice, and reduce the oxidation rate, significantly improving the purity of the juice and the retention rate of nutrients. It can solve the problems of incomplete separation of pulp and juice in traditional juicers, easy oxidation of juice when in contact with air, resulting in deterioration of taste and loss of nutrients.

[0018] 2. This utility model, by setting a variable diameter spiral shaft inside the juicing cylinder, utilizes the structural feature that the pitch gradually decreases from the feeding end to the residue discharge end to form a dynamic pressurization space inside the juicing cylinder. With the drive of a servo motor, the lemons are squeezed with variable volume, which can improve the lemon juice extraction rate compared to the traditional constant diameter spiral shaft. At the same time, the squeezed residue is directly introduced into the top of the centrifugal basket through the residue discharge cylinder, and the residue is spun dry again by centrifugal force, which reduces the moisture content of the residue. Users can remove it all at once through the top cleaning cover. This can solve the problems of low raw juice utilization rate, high juice content of residue, and difficulty in cleaning due to moisture and adhesion in traditional juicers.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a novel oxygen-free lemon juicer, comprising a juicer body 1, wherein a centrifugal separation component is installed inside the juicer body 1, the centrifugal separation component being used to further separate the solid and liquid components of the initially extracted lemon juice and to delay the oxidation of the juice.

[0028] The centrifugal separation component includes a centrifugal chamber 2 installed inside the juicer body 1. A servo motor 3 is installed at the bottom of the centrifugal chamber 2. The output end of the servo motor 3 is connected to a centrifugal basket 4, and the centrifugal basket 4 is located inside the centrifugal chamber 2. The centrifugal basket 4 is a 304 stainless steel woven mesh structure with a pore size of 0.3mm±0.02mm and an opening rate of ≥65%, which can intercept fruit pulp with a particle size >0.3mm.

[0029] The bottom of centrifuge chamber 2 is connected to a first conveying pipe 5, the bottom of which is connected to a conveying pump 6, and the bottom of the conveying pump 6 is connected to a second conveying pipe 7. The first conveying pipe 5 and the second conveying pipe 7 are made of transparent food-grade TPU tubing (8mm inner diameter, 1.5mm wall thickness), and quick-release connectors (model: QKJ-08) at both ends are connected to the centrifuge chamber and the conveying pump 6.

[0030] Furthermore, the centrifugal separation component is the core innovation that distinguishes it from traditional juicers. It achieves dual functions through physical centrifugal force and a closed environment. The centrifugal chamber 2 is a closed cavity with a smooth inner wall and a gap between it and the centrifugal basket 4, ensuring that the centrifugal basket 4 does not rub against the chamber wall when rotating at high speed.

[0031] A silicone sealing ring 20 (3mm thick, temperature resistant -20℃~150℃) is installed between the upper layer of the centrifuge chamber 2 and the cleaning cover 18. A mechanical seal 21 (model: MG1-25, with silicon carbide material for the moving and stationary rings) is used between the lower layer of the centrifuge chamber 2 and the rotating shaft of the centrifuge basket 4. The inner wall of the centrifuge chamber 2 is polished to Ra≤0.8μm to reduce juice adhesion.

[0032] Servo motor 23 is fixed at the bottom of centrifuge chamber 2. Its output shaft is connected to the central shaft of centrifuge basket 4 via a coupling. It can drive centrifuge basket 4 to rotate at a speed of 2000-3000 rpm, which is adjustable. The basket body of centrifuge basket 4 has a hollow mesh structure. When the fruit pulp falls into the basket from the pulp discharge cylinder 12, the centrifugal force generated by the high-speed rotation causes the residual juice to pass through the mesh and be thrown towards the wall of centrifuge chamber 2. The fruit pulp adheres to the inner side of the basket wall due to the centrifugal force. The separated juice gathers at the bottom of centrifuge chamber 2 and flows into the delivery pump 6 through delivery pipe 15. After being pressurized, it is delivered to lemon juice storage chamber 19 through delivery pipe 27.

[0033] Centrifuge chamber 2 is in a closed state during operation, reducing the contact area between the juice and air. The centrifugation process is short, which can significantly delay the oxidation of vitamin C and maintain the freshness of the juice.

[0034] The first delivery pipe 5 connects the bottom of the centrifuge chamber 2 to the inlet of the delivery pump 6, using gravity to assist the flow of juice and avoid residue. The delivery pump 6 is a positive displacement pump, which can provide stable pumping pressure to ensure that the juice after centrifugation flows back to the lemon juice storage chamber 19 through the second delivery pipe 7 and mixes with the initially extracted juice, realizing full-process automation.

[0035] The closed-loop design of the pulp discharge cylinder 12, centrifuge basket 4, conveying pipe one 5, conveying pump 6 to conveying pipe two 7 increases the recovery rate of residual juice in fruit pulp by about 20%-30%, making it more energy-efficient and effective than traditional juicers.

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 One embodiment of this utility model is a novel oxygen-free lemon juicer. The juicer body 1 is connected to a juicer cylinder 8, and the bottom of the juicer cylinder 8 is provided with evenly arranged leakage holes 9.

[0037] The juicer body 1 is equipped with a servo motor 10 inside. The output end of the servo motor 10 is connected to a variable diameter screw shaft 11. The variable diameter screw shaft 11 is located inside the juicing cylinder 8, and one end of the variable diameter screw shaft 11 is connected to the side wall of the juicing cylinder 8.

[0038] The juicer body 1 has a lemon juice storage chamber 19 inside, and the lemon juice storage chamber 19 is located below the juicing cylinder 8 and the servo motor 10.

[0039] A pulp discharge cylinder 12 is connected to one side of the juicing cylinder 8, and one end of the pulp discharge cylinder 12 is located at the top of the centrifuge basket 4.

[0040] Furthermore, the juicing cylinder 8 is the core component for initial juicing. Its internal structure works in conjunction with the power system to achieve initial solid-liquid separation. The juicing cylinder 8 has a cylindrical body with numerous perforations 9 at the bottom. The perforations are evenly distributed to ensure smooth dripping of juice while blocking larger fruit pulp particles.

[0041] The variable diameter screw shaft 11 passes through the juicing cylinder 8. One end is fixed to the cylinder wall by a bearing, and the other end is rigidly connected to the output shaft of the servo motor 10. The diameter of the screw shaft gradually decreases from the feeding end to the slag discharge end, forming a conical extrusion space.

[0042] Servo motor 10 drives variable diameter screw shaft 11 to rotate clockwise. After the lemon falls into the juicing cylinder 8 from the feed port 16, it is pushed by the screw blades to move towards the pulp discharge end. As the diameter of the screw shaft gradually decreases, the squeezing pressure on the lemon pulp gradually increases. The juice flows into the lemon juice storage chamber 19 below through the drain hole 9, while the dry and hard pulp is transported to the top of the centrifuge basket 4 through the pulp discharge cylinder 12, waiting for further processing.

[0043] The lemon juice storage chamber 19 is located directly below the juicing cylinder 8. It is made of food-grade stainless steel with a smooth and easy-to-clean inner wall. It can temporarily store the juice that has been initially extracted, providing a buffer time for subsequent centrifugal separation.

[0044] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of this utility model is a novel oxygen-free lemon juicer. The juicer body 1 has a feed inlet 16 at the top, and the feed inlet 16 is located above the juicing cylinder 8. The top of the feed inlet 16 is provided with a feed cover 17.

[0045] The juicer body 1 is provided with a cleaning cover 18 on the top, and the cleaning cover 18 is located above the centrifuge chamber 2.

[0046] The bottom of the juicer body 1 is provided with evenly distributed supports 13;

[0047] The juicer body 1 has a liquid outlet pipe 14 at the bottom, and a valve 15 at the bottom end of the liquid outlet pipe 14.

[0048] Furthermore, the feed inlet 16 is located directly above the juicing cylinder 8, making it convenient for users to add lemon raw materials to be squeezed. The matching feed cover 17 is sealed by a snap-fit ​​structure to prevent juice from splashing or foreign objects from falling in during juicing.

[0049] The cleaning cover 18 covers the top of the centrifuge chamber 2 and is connected by magnetic or threaded means. It can be quickly removed, which makes it easy to clean the fruit pulp and juice residue inside the centrifuge chamber 2 regularly and avoid the growth of bacteria.

[0050] The supports 13 are evenly distributed at the bottom of the main body. In addition to providing stable support, they can also buffer motor vibration and reduce noise.

[0051] The outlet pipe 14 is connected to the lemon juice storage chamber 19, and the valve 15 at the end is used to control the juice discharge. Users can open or close it at any time as needed, which makes it convenient to collect lemon juice in batches.

[0052] Working principle: The user opens the feed cover 17, puts the lemon into the feed port 16, and then closes the feed cover 17 to seal it. The lemon falls into the juicing cylinder 8 and is located at the feed end of the variable diameter screw shaft 11, that is, the side with the larger diameter of the screw shaft.

[0053] When the servo motor 10 starts, it drives the variable diameter spiral shaft 11 to rotate clockwise. The spiral blades push the lemon towards the pulp discharge end, that is, the side with a smaller spiral shaft diameter. As the spiral shaft diameter gradually decreases, the squeezing force on the lemon pulp gradually increases.

[0054] The juice in the pulp is squeezed out and drips through the hole 9 at the bottom of the juicing cylinder 8 into the lemon juice storage chamber 19 below for temporary storage. The dry and hard pulp is pushed to the pulp discharge cylinder 12 and slides down the pipe to the top of the centrifuge basket 4.

[0055] Fruit pulp sliding down from the discharge cylinder 12 falls into the centrifuge basket 4. At this time, the servo motor 2 3 starts and drives the centrifuge basket 4 to rotate at a high speed of 2000-3000 rpm. The hollow mesh structure of the centrifuge basket 4 intercepts the fruit pulp in the basket, while the residual juice passes through the mesh under the action of centrifugal force, is thrown towards the inner wall of the centrifuge chamber 2, and gathers at the bottom of the chamber.

[0056] The separated juice flows into the delivery pump 6 through the delivery pipe 5. After being pumped and pressurized, it flows back to the lemon juice storage chamber 19 through the delivery pipe 7 and mixes with the initially extracted juice.

[0057] Centrifuge chamber 2 is a closed cavity that is isolated from the outside air during operation, reducing the contact area between the juice and oxygen. The centrifugation process is completed quickly, significantly shortening the time the juice is exposed to air, delaying the oxidation of vitamin C, and maintaining the color and nutrients of the juice.

[0058] The mixed lemon juice is stored in the lemon juice storage chamber 19. The user opens the valve 15 at the end of the liquid outlet pipe 14, and the juice is discharged through the bottom pipe. It can be collected directly or connected to the subsequent packaging process.

[0059] After centrifugation, turn off servo motor 23, open cleaning cover 18, remove centrifuge basket 4, and pour out the remaining fruit pulp.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
