Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a cold-pressed deastringency removal device for mandarin orange juice. Background Technology

[0002] The market demand for mandarin orange juice is gradually increasing due to its rich content of vitamins, polyphenols and other nutrients. However, the tannins contained in mandarin oranges can easily make the juice taste bitter, affecting the palatability of the product. Therefore, the de-astringency treatment of mandarin orange juice is a key step in the processing.

[0003] In the processing of mandarin orange juice, astringency removal is a crucial step that determines the product's taste. Uniform mixing of the juice and the astringent agent during this process is essential for ensuring effective astringency removal. However, existing mandarin orange juice astringency removal devices suffer from the following problems: The connection between the stirring structure and transmission components of existing devices is simple, and after long-term operation, the stirring components are prone to loosening or shifting, resulting in insufficient mixing of the astringent agent and mandarin orange juice, leading to incomplete astringency removal in some areas and affecting the consistency of the product's taste. Furthermore, the stirring components of existing devices are mostly single-blade structures and lack dedicated fixing components, resulting in insufficient stability of the blades during stirring and a tendency to shake, further reducing the uniformity of mixing.

[0004] To address the problem of uneven mixing in the deastringency removal process, there is an urgent need for a deastringency removal device for mandarin orange juice with a stable mixing structure and reliable mixing effect, so as to improve the processing efficiency and stability of the deastringency removal process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cold-pressed mandarin orange juice de-astringency device. This device solves the problem that de-astringency is a crucial step in the processing of mandarin orange juice, determining the product's taste. Uniform mixing of the juice and the de-astringent agent is essential for ensuring effective de-astringency. However, existing mandarin orange juice de-astringency devices suffer from the following problems: the connection between the stirring structure and transmission components is simple, leading to loosening and misalignment of the stirring components after long-term operation. This results in insufficient mixing of the de-astringent agent and the mandarin orange juice, incomplete de-astringency in some areas, and affects the consistency of the product's taste. Furthermore, the stirring components of existing de-astringency devices are mostly single-blade structures, lacking dedicated fixing components. This results in insufficient stability of the blades during stirring, causing them to wobble and further reducing the technical problem of uniform mixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cold-pressed deastringency removal device for mandarin orange juice includes a main tank with a top cover. The top cover has a handle, a deastringent storage chamber, and a motor. The motor has a switch knob. A liquid inlet chamber is connected to the outside of the main tank, and a liquid inlet pipe connects the liquid inlet chamber to the main tank. A liquid outlet valve and support feet are located at the bottom of the main tank. The motor is connected to a drive shaft, and a stirring blade is connected to the drive shaft. The stirring blade is fixed to the drive shaft by a fixing seat, which can improve the connection stability of the stirring blade to ensure uniform mixing. A deastringent inlet valve connects the deastringent storage chamber to the main tank, which can precisely control the supply of the deastringent to optimize the deastringency effect.

[0007] Preferably, the top cover is located above the main tank and closes to the top opening of the main tank, which can enhance the sealing of the main tank to reduce external pollution; the top cover handle is located above the top cover and is fixedly connected to the upper surface of the top cover, making it convenient for operators to open or close the top cover.

[0008] Preferably, the liquid inlet chamber is connected to the outer wall of the main tank and communicates with the interior of the main tank through the liquid inlet pipe, which enables stable delivery of mandarin orange juice to assist the deastringency process; the deastringent storage chamber is connected to the outer wall of the main tank and communicates with the interior of the main tank through the liquid inlet pipe; a deastringent feed valve is connected between the deastringent storage chamber and the main tank, which can flexibly control the timing of adding the deastringent to improve the deastringency efficiency.

[0009] Preferably, one end of the drive shaft is connected to the output end of the motor, and the other end extends into the interior of the main tank, which can efficiently transmit power to drive the stirring components.

[0010] Preferably, the fixing seat is sleeved on the outside of the drive shaft and connected to the stirring blade, which can strengthen the connection between the stirring blade and the drive shaft and prevent the components from loosening during the stirring process.

[0011] Preferably, the support foot is located below the main body tank and is fixedly connected to the bottom outer wall of the main body tank, which can improve the overall placement stability of the device.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The stirring blades are securely connected to the drive shaft via a fixed base, avoiding the problems of loosening and misalignment common in traditional stirring components. This significantly improves the mixing uniformity of the deastringent agent and the mandarin orange juice, ensuring consistent deastringency results. The integrated structure connecting the deastringent agent storage chamber, the liquid inlet chamber, and the main tank, along with the deastringent agent inlet valve and inlet pipe, enables closed-loop and precise delivery of the deastringent agent and auxiliary materials, reducing manual operation steps and improving the efficiency of the deastringency process.

[0013] The sealed lid structure between the top cover and the main tank reduces the risk of juice contamination from external sources, while the bottom support feet enhance the overall stability of the device. The lid handle also facilitates quick opening and closing. Integrating the storage, conveying, and stirring components related to deacidification into a single unit eliminates the need for separate equipment, reducing space requirements and minimizing juice loss and contamination during transfer.

[0017] This application provides a cold-pressed mandarin orange juice de-astringency device, which effectively solves the problem that de-astringency is a key process in the processing of mandarin orange juice, determining the product's taste. Uniform mixing of the juice and the de-astringent agent is crucial for ensuring the de-astringency effect. However, existing mandarin orange juice de-astringency devices have the following problems: the connection between the stirring structure and transmission components of existing devices is simple, and after long-term operation, the stirring components are prone to loosening and shifting, resulting in insufficient mixing of the de-astringent agent and mandarin orange juice, incomplete de-astringency in some areas, and affecting the consistency of the product's taste; the stirring components of existing devices are mostly single-blade structures and lack dedicated fixing components, resulting in insufficient stability of the blades during stirring, easily causing shaking, further reducing the technical problem of mixing uniformity.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that in the processing of mandarin orange juice, astringency removal is a key process that determines the product's taste. Uniform mixing of the juice and the astringent during astringency removal is crucial for ensuring the effectiveness of the removal process. However, existing mandarin orange juice astringency removal devices have the following problems: the connection between the stirring structure and transmission components of existing devices is simple, and after long-term operation, the stirring components are prone to loosening or shifting, resulting in insufficient mixing of the astringent and mandarin orange juice, incomplete astringency removal in some areas, and affecting the consistency of the product's taste; the stirring components of existing devices are mostly single-blade structures and lack dedicated fixing components, resulting in insufficient stability of the blades during stirring and easy shaking, further reducing the technical problem of mixing uniformity. The overall approach is as follows: To address the problems existing in the prior art, this utility model provides a cold-pressed deastringency removal device for mandarin orange juice, including a cylindrical hollow main tank 1. A food-grade stainless steel circular flat top cover 2 is fitted over the top opening of the main tank 1. The edge of the top cover 2 is sealed to the top opening of the main tank 1 by a sealing ring to reduce the entry of external air and impurities into the main tank 1 and reduce the risk of mandarin orange juice contamination. A top cover handle 3 is welded to the center of the upper surface of the top cover 2. The two ends of the top cover handle 3 are vertically welded to the upper surface of the top cover 2, and its height is higher than the top of the subsequent components, making it easy for the operator to hold and quickly open or close the top cover 2. A cylindrical deastringency storage chamber 4 with a sealing structure is fixedly installed on one side of the surface of the main tank 1. A transparent observation window is provided on the side wall of the deastringency storage chamber 4. A vertical cylindrical motor 5 is fixed on the other side of the upper surface of the top cover 2. A ring-shaped rotary switch knob 6 is provided on the top of the motor 5. A liquid inlet chamber 7 is welded to the upper part of the outer side wall of the main tank 1. The top of the liquid inlet chamber 7 is provided with a circular opening. The bottom outlet of the liquid inlet chamber 7 is connected to a liquid inlet pipe 8. The end of the liquid inlet pipe 8 away from the liquid inlet chamber 7 passes through the side wall of the main tank 1 and communicates with the interior. The connection is sealed by welding to achieve stable delivery of mandarin orange juice and ensure continuous operation of the de-astringency process. A liquid outlet valve 9 with a spherical shut-off valve structure is embedded in the center of the bottom of the main tank 1. Four columnar support feet 10 are evenly welded to the circumference of the bottom outer side wall of the main tank 1. The four support feet 10 are distributed in a rectangular shape to improve the overall stability of the device on the ground and prevent shaking during the stirring process.

[0019] The output end of the motor 5 is coaxially connected to a cylindrical rod-shaped drive shaft 11 via a coupling. The drive shaft 11 extends vertically downward into the interior of the main tank 1. An annular sleeve-shaped fixing seat 13 is fitted in the middle of the outer wall of the drive shaft 11. The drive shaft 11 is locked and fixed by the fixing seat 13. Six flat stirring blades 12 are uniformly welded around the outer wall of the fixing seat 13 to enhance the connection stability of the stirring blades 12 and ensure that the deastringent agent and the citrus juice are mixed evenly.

[0020] The bottom outlet of the deabrasive storage chamber 4 is connected to a cylindrical tubular deabrasive feed valve 14. The deabrasive feed valve 14 adopts a ball valve structure, with its valve stem extending to the outside and equipped with a rotating handle. This allows for direct observation of the remaining amount of deabrasive, precise control of the deabrasive delivery, and flexible adjustment of the addition timing, thereby optimizing the deabrasive effect and improving the deabrasive efficiency.

[0021] Working principle: The top cover 2 is opened via the top cover handle 3. After checking the cleanliness of the main tank 1, the top cover 2 is closed, and the sealing ring on the edge of the top cover 2 achieves a seal on the main tank 1. The amount of deacidifying agent stored is confirmed through the transparent observation window on the side wall of the deacidifying agent storage chamber 4 to ensure that the deacidification requirements are met. The support feet 10 are in contact with the ground through the bottom rubber anti-slip pads to ensure the overall stability of the device. The cold-pressed orange juice is injected through the rectangular opening at the top of the inlet chamber 7. The orange juice flows along the inside of the inlet chamber 7 to the bottom outlet, and is stably transported to the inside of the main tank 1 through the inlet pipe 8. The welded sealing structure between the inlet pipe 8 and the main tank 1 prevents juice leakage and ensures that the orange juice enters the deacidification environment in a sealed manner. The operator adjusts the valve opening by rotating the handle on the outside of the deastringent feed valve 14. The deastringent in the deastringent storage chamber 4 flows precisely into the main tank 1 along the cylindrical tube deastringent feed valve 14. The amount of deastringent added is flexibly adjusted in combination with the total amount of mandarin orange juice to achieve the appropriate ratio of deastringent to mandarin orange juice. The motor 5 is started by the switch knob 6 on the top of the motor 5. The power output of the motor 5 is transmitted to the drive shaft 11 through the coupling. The drive shaft 11 rotates with low friction under the support of the bearing. The fixed seat 13 sleeved on the drive shaft 11 rotates synchronously with the drive shaft 11, driving the three circumferentially welded stirring blades 12 to stir evenly inside the main tank 1. The locking structure of the fixed seat 13 and the drive shaft 11 with the set screw ensures that the stirring blades 12 are not loose or deviated, so that the deastringent agent and the mandarin orange juice can fully contact and mix evenly. The deastringent agent acts quickly on the bitter substances in the mandarin orange juice to complete the deastringency reaction. After stirring and mixing for a period of time, once the deastringency reaction is complete, the operator opens the outlet valve 9 at the bottom of the main tank 1. The outlet valve 9, with its spherical shut-off valve structure, can precisely control the discharge speed. The deastringent orange juice is stably discharged through the outlet valve 9 and can be collected for further processing or used directly. The motor 5 and outlet valve 9 are then turned off. If further operation is required, the above process can be repeated. After the operation is completed, the top cover 2 is opened to clean the inside of the main tank 1, ensuring the hygiene of the equipment and its stability for future use.

[0022] Example 1 The main tank 1 is made of 304 stainless steel and has a cylindrical hollow structure. A stainless steel circular flat top cover 2 covers the top opening, with silicone sealing rings embedded along its edges. A U-shaped stainless steel top cover handle 3 is welded to the center of its upper surface. A motor 5 is fixed to the other side, and a plastic switch knob 6 is embedded on the top of the motor 5. A stainless steel hollow liquid inlet chamber 7 is welded to the upper part of the outer wall of the main tank 1. The bottom outlet of the liquid inlet chamber 7 is connected to a stainless steel liquid inlet pipe 8, the other end of which passes through the main tank 1 and is welded and sealed. A stainless steel ball-shaped shut-off valve 9 is embedded in the center of the bottom of the main tank 1. Four rectangular cylindrical stainless steel support feet 10 are evenly welded to the circumference of the bottom outer wall. The output end of the motor 5 is connected to a stainless steel drive shaft 11 via a coupling. The lower end of the drive shaft 11 is inside the main tank 1, and a stainless steel sleeve fixing seat 13 is fitted onto the middle of its outer wall. Six flat plates are evenly welded to the circumference of the outer wall. The stainless steel stirring blade 12 and the bottom outlet of the deastringent storage chamber 4 are connected to the cylindrical stainless steel deastringent feed valve 14, with the valve stem extending to the outside and equipped with a rotating handle. During use, the operator opens the top cover 2 through the top cover handle 3 to check the cleanliness and then closes the seal. The deastringent storage chamber 4 is checked through the observation window to confirm the deastringent storage level. The cold-pressed mandarin orange juice is injected through the top opening of the liquid inlet chamber 7 and transported to the main tank 1 through the liquid inlet pipe 8. The deastringent is added precisely by adjusting the valve opening through the rotating handle of the deastringent feed valve 14. The switch knob 6 is pressed to start the motor 5. The power is transmitted to the drive shaft 11 through the coupling. The drive shaft 11 drives the fixed seat 13 and the stirring blade 12 to rotate stably under the support of the bearing, so that the deastringent and mandarin orange juice are fully mixed to complete the deastringent reaction. After deastringenting, the liquid outlet valve 9 is opened to control the discharge speed and collect the juice. After the operation is completed, the top cover 2 is opened to clean the equipment for reuse.

[0023] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
