A citrus processing juicer

Abstract

This utility model relates to the field of citrus processing technology, specifically a citrus juicing device, including a housing with ventilation windows on both sides. Two inspection doors are movably installed on the side of the housing away from the ventilation windows. A control switch is installed on one side of each inspection door. A support is fixedly installed on the upper surface of the housing, connecting the device to a factory power supply. When the device is working, the motor (a commercially available product) is started via the control switch. The motor output drives a screw rod to rotate within a conical pressing chamber via a coupling. Citrus fruits are fed into the inlet and pushed by the rotating screw rod, squeezed within the constricted space of the conical pressing chamber. The extracted juice passes through the filter holes of a filter screen into the support, and is then discharged through a discharge pipe controlled by a valve. The residue produced during pressing is pushed by the screw rod towards the side of the filter screen near the discharge port, and discharged through a groove from the discharge port, thus completing the citrus juicing, filtering, and residue removal process.

Description

Technical Field

[0001] This utility model relates to the field of citrus processing technology, and in particular to a juicing device for citrus processing. Background Technology

[0002] Citrus processing is the process of transforming citrus fruits such as oranges, tangerines, grapefruits, and lemons into various edible or industrial products through physical, chemical, or biological technologies. The core value of this industry lies in extending the shelf life of citrus fruits, increasing their added value, and reducing losses caused by improper storage and transportation. It is of great significance for the efficient use of agricultural resources. In the food sector, fruit juice and fruit juice beverages are the main products of citrus processing. The process begins with mechanical pressing to obtain the original juice, followed by centrifugal filtration to remove pulp residue. Then, pasteurization or ultra-high temperature (UHT) sterilization is used to kill microorganisms. Finally, aseptic filling produces 100% pure orange juice, lemon juice, and other products. Some beverages are formulated with added sugar and vitamins to create a variety of flavored compound fruit juice drinks. Canned products focus on utilizing the fruit pulp; for example, canned oranges require hot water rinsing to remove the peel, manual segmentation to remove the pith, and then the segments are immersed in sugar syrup, vacuum-sealed, and sterilized at high temperatures to achieve long-term preservation at room temperature. Furthermore, citrus processing has extended to include candied fruits, jellies, and other snack foods. Processes such as sugaring and drying lock in the fruit's aroma. In industrial applications, citrus peels and pulp can be extracted to obtain raw materials such as pectin and essential oils. Pectin is a commonly used thickener in the food industry, while essential oils are widely used in cosmetics and detergents for flavoring. These deep-processing steps transform citrus from "fresh fruit" into a "resource across the entire industry chain," enriching market supply and injecting sustained vitality into the agricultural economy.

[0003] Traditional juicing methods are inefficient and fail to completely separate juice from pulp, making it difficult to meet the needs of large-scale processing. This device is designed to solve these problems.

[0004] To adapt to the citrus processing scenario, the equipment needs to have efficient juicing capabilities, effectively separate juice from pulp, be easy to operate and maintain, and meet the hygiene standards of food processing, so as to improve processing efficiency, reduce labor costs, and meet the market's requirements for the quality and quantity of citrus juice processing. Utility Model Content

[0005] The purpose of this utility model is to provide a juicing device for citrus processing, which solves the problems mentioned in the background art of low efficiency, incomplete separation of juice and pulp in traditional juicing methods, and difficulty in meeting the needs of large-scale processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a juicing device for citrus processing, comprising a housing, with heat dissipation windows on both sides of the housing, and two inspection doors movably installed on the side of the housing away from the heat dissipation windows. A control switch is installed on one side of each inspection door. A circular support is fixedly installed on the upper surface of the housing, and a pressing chamber is fixedly installed on the upper surface of the support. The pressing chamber is conical, and a feed inlet is opened on one side of the upper surface of the pressing chamber. A juicing assembly is installed inside the pressing chamber.

[0007] The juicing assembly includes a motor, which is fixedly installed at the top of the inside of the housing. The motor is longitudinally positioned and electrically connected to a control switch. A discharge pipe is fixedly installed on one side of the support platform, and a valve is movably installed on the upper surface of the discharge pipe.

[0008] The support platform has a slag discharge port on the side away from the discharge pipe, and a filter screen is fixedly installed inside the support platform. The filter screen is made of stainless steel.

[0009] The filter screen has a groove on the side near the slag discharge port, the groove is connected to the slag discharge port, and the filter screen has a number of filter holes inside.

[0010] The filter screen is internally connected to a coupling, and the bottom end of the coupling is fixedly connected to the output end of the motor.

[0011] The pressing chamber is rotatably connected to a conical screw rod. The top end of the screw rod is rotatably connected to the pressing chamber, and the bottom end of the screw rod is fixedly connected to a coupling.

[0012] This utility model discloses a citrus juicing device with significant advantages. It employs a matching design between a conical screw and a conical pressing chamber, combined with a stainless steel filter screen, achieving integrated and efficient operation of juicing, filtering, and pulp discharge. When the screw rotates, the conical structure's contraction space fully compresses the citrus fruit, increasing the juice extraction rate. The filter screen's pores effectively separate juice from pulp, while the interconnected design of the groove and pulp discharge port ensures smooth residue discharge and reduces clogging. Simultaneously, ventilation windows on both sides of the casing ensure stable motor operation, and the inspection door facilitates future maintenance. The overall structure is compact with clearly defined functional areas. This device significantly improves the efficiency and convenience of citrus processing. Its detailed design is particularly advantageous. The longitudinally mounted motor drives the screw rod via a coupling, ensuring stable transmission and low power loss. The control switch allows for flexible adjustment of motor operation, making it easy to use. The stainless steel filter screen is not only corrosion-resistant and easy to clean, meeting food processing hygiene standards, but its ingenious integration with the support platform allows juice to flow through the filter holes into the discharge pipe. Discharge is controlled by a valve, enabling controllable juice collection. The precise alignment of the slag discharge port with the filter screen groove prevents residue buildup, reducing cleaning costs. Suitable for small to medium-sized citrus processing scenarios, it balances practicality and economy. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a juicing device for citrus processing, including a housing 1, with heat dissipation windows 2 on both sides of the housing 1. Two inspection doors 3 are movably installed on the side of the housing 1 away from the heat dissipation windows 2. A control switch 4 is installed on one side of each inspection door 3. A circular support platform 5 is fixedly installed on the upper surface of the housing 1. A conical pressing chamber 6 is fixedly installed on the upper surface of the support platform 5. A feed inlet 7 is opened on one side of the upper surface of the pressing chamber 6. A juicing assembly 8 is installed inside the pressing chamber 6. The working principle of this citrus processing juicing device is based on the coordinated operation of mechanical pressing and power transmission. After the operator starts the device through the control switch next to the inspection door, the housing... The internal motor and other power components start working, and the power is transmitted to the juicing components in the pressing chamber through the transmission device. The citrus fruits to be processed are put into the feed port on the upper surface of the pressing chamber and gathered towards the center under the guidance of the conical pressing chamber. At this time, the juicing components start to operate, crushing and pressing the citrus fruits through the rotation or squeezing action of the pressing parts, so that the juice seeps out. During the juicing process, the filtration structure separates the juice from the pulp. The pure juice flows out and is collected through the preset channel, while the pulp is discharged from the pressing chamber. At the same time, the heat dissipation windows on both sides of the box continuously dissipate heat for the internal power components, ensuring stable operation of the device. Operators can check and maintain the internal condition of the device at any time through the maintenance door.

A filter screen 13 is fixedly installed inside the support platform 5. The filter screen 13 is made of stainless steel. A groove 14 is opened on the side of the filter screen 13 near the slag discharge port 12, and the groove 14 communicates with the slag discharge port 12. Several filter holes 15 are opened inside the filter screen 13. A coupling 16 is rotatably connected inside the filter screen 13. The bottom end of the coupling 16 is fixedly connected to the output end of the motor 9. A conical screw rod 17 is rotatably connected inside the pressing chamber 6. The top of the screw rod 17 is rotatably connected to the pressing chamber 6, and the bottom of the screw rod 17 is fixedly connected to the coupling 16, connecting the device to the factory power supply. When the device is working, the motor 9 is started by the control switch 4. The motor 9 is a commercially available product. The output end of the motor 9 drives the screw rod 17 to rotate inside the conical pressing chamber 6 via the coupling 16. After the citrus is put into the feed port 7, it is pushed by the rotating screw rod 17 and squeezed in the contraction space of the conical pressing chamber 6. The squeezed juice enters the inside of the support 5 through the filter holes 15 of the filter screen 13, and can be discharged through the discharge pipe 10 by the valve 11. The residue produced by pressing is pushed by the screw rod 17 to the side of the filter screen 13 near the slag discharge port 12, and discharged from the slag discharge port 12 through the groove 14, thus completing the citrus juicing, filtering and slag discharge process.

[0022] Working principle: Connect the device to the factory power supply. When the device is working, start the motor 9 via the control switch 4. The motor 9 is a commercially available product. The output end of the motor 9 drives the screw rod 17 to rotate in the conical pressing chamber 6 via the coupling 16. After the citrus is put into the feed port 7, it is pushed by the rotating screw rod 17 and squeezed in the concave space of the conical pressing chamber 6. The juice is squeezed through the filter holes 15 of the filter screen 13 and enters the inside of the support 5. It can be discharged through the discharge pipe 10 and controlled by the valve 11. The residue produced by pressing is pushed by the screw rod 17 to the side of the filter screen 13 near the slag discharge port 12 and discharged from the slag discharge port 12 through the groove 14, thus completing the citrus juicing, filtering and slag discharge process.
