Description

Technical Field

[0001] This utility model relates to the technical field of post-harvest fruit processing equipment, specifically to a physical deacidification and deastringency removal device for fruits. Background Technology

[0002] Acidity and astringency are key factors affecting the taste and commercial value of fruits. Unripe fruits often contain high concentrations of organic acids (such as citric acid and malic acid) and tannins (tannic acid), resulting in a sour and astringent taste that limits their suitability for consumption and processing. Therefore, post-harvest treatment of fruits (including deacidification, deastringency removal, and ripening) is a crucial step in enhancing their commercial value.

[0003] When using physical methods (carbon dioxide + heating) to deacidify and de-astringent fruits, traditional processing devices often use a stacking method, lacking a reasonable support structure. During the processing, the fruits are squeezed together, which can easily cause damage. This not only seriously affects the appearance and quality of the fruits, but also reduces their commercial value, resulting in economic losses for fruit farmers and processing enterprises.

[0004] Therefore, it is necessary to provide a physical deacidification and deastringency removal device for fruits to solve the problems mentioned in the background art. Utility Model Content

[0017] Please see Figure 1-4 This utility model provides a physical deacidification and deastringency removal device for fruits, including a processing tank 1. The processing tank 1 is provided with a cylindrical processing cavity, and a number of windows 5 are longitudinally spaced on the tank wall of the processing tank 1, which are connected to the processing cavity. A fruit-supporting assembly 2 is horizontally rotatably mounted on the outer wall of the processing tank 1. The fruit-supporting assembly 2 is driven to rotate by a rotary driver 9 and can rotate through the window 5 in the direction of the inside and outside of the processing tank 1. After the fruit-supporting assembly 2 rotates into the processing tank 1, it is sealed and engaged with the end face of the window 5. The fruit holding assembly 2 is detachably equipped with a tray 7 for placing the fruit to be processed; An air inlet pipe 3 is installed at the top of the processing tank 1. The air inlet pipe 3 is connected to an external gas tank and is used to deliver carbon dioxide gas into the processing tank 1. A heater 4 is installed at the air inlet end of the air inlet pipe 3 to heat the input carbon dioxide gas.

[0018] Specifically, the heater 4 is an electric heating tube heat exchanger or a microchannel heat exchanger, and the heater 4 is installed on the pipeline of the air inlet pipe 3 to heat the transported carbon dioxide gas.

[0019] When deacidifying and de-astringing fruits, the rotary actuator 9 drives the fruit-supporting assembly 2 to rotate outside the processing tank 1. Then, a forklift places the fruit-loaded tray 7 onto the fruit-supporting assembly 2. The rotary actuator 9 then drives the fruit-supporting assembly 2 into the processing chamber. At this point, the fruit-supporting assembly 2 is sealed to the window 5, isolating the processing chamber from the external environment. Carbon dioxide gas is then introduced into the processing chamber through the air inlet pipe 3, and simultaneously heated by the carbon dioxide gas in the heater 4, thus changing the environmental conditions inside the processing chamber and performing deacidification and de-astringency treatment on the fruits. The rotary actuator 9 is a servo motor. By adjusting the heating temperature of the heater 4, the device can adapt to different fruit deacidification and de-astringency treatments, improving its adaptability.

[0020] By setting up the fruit support assembly 2 and the tray 7, the height of fruit stacking in the vertical space of the device is increased. At the same time, it avoids excessive stacking of fruit during processing, which can cause crushing and affect the quality of the fruit. Meanwhile, by setting up the rotary drive 9, the fruit support assembly 2 can be automatically rotated out or into the processing tank 1, reducing the labor intensity of the staff and improving the space utilization of the device.

[0021] Furthermore, the fruit support assembly 2 includes a mounting plate 8, a connecting plate 10, and a C-shaped support 11; The mounting plates 8 are horizontally and symmetrically installed at the upper and lower ends of each window 5. A rotating shaft is rotatably provided between the mounting plates 8. One end of the rotating shaft passes through the mounting plate 8 upward and is used to connect the rotary driver 9. A connecting plate 10 is fixedly provided on the outer circumference of the rotating shaft; The connecting plate 10 is fixedly connected to the outer end of the C-shaped support 11. A C-shaped support plate 12 is fixedly provided in the middle of the inner side of the C-shaped support 11, and the tray 7 is placed on the C-shaped support plate 12.

[0022] Specifically, the rotary drive 9 drives the rotating shaft to rotate, which in turn drives the C-shaped support 11 to rotate. When it rotates into the processing tank 1, deacidification and desulfurization treatment is carried out inside the processing tank 1. When it rotates to the outside of the processing tank 1, it is convenient to remove the tray 7. The C-shaped support 11 and the C-shaped support plate 12 facilitate the placement and removal of the tray 7, improving work efficiency.

[0023] Furthermore, in order to improve the sealing performance of the C-shaped bracket 11 and the window 5, a step 18 is provided at the outer end of the window 5 along its opening trajectory, and a sealing gasket is attached to the step 18. The shape of the C-shaped support 11 is adapted to the shape of the step 18.

[0024] The C-shaped bracket 11 is fitted onto the window 5 by rotating the rotary driver 9, thereby sealing the window 5.

[0025] Preferably, the sealing gasket is embedded with a pressure sensing unit, and the pressure sensing unit and the rotary driver 9 are respectively connected to the controller. When the pressure sensing unit detects a pressure value set threshold, the controller controls the rotary driver 9 to stop rotating and maintain its position.

[0026] Furthermore, the adjacent fruit-holding components 2 are respectively installed at both ends of the window 5 to avoid interference when they are on the same side, thereby improving space utilization.

[0027] Furthermore, the tray 7 is a circular tray with several evenly spaced ventilation holes 14. This facilitates the passage of carbon dioxide gas. Since carbon dioxide gas is denser than air, it gradually accumulates and rises, allowing the fruit to come into full contact with the carbon dioxide and improving the processing effect.

[0028] Furthermore, both ends of the C-shaped support plate 12 extend to the outer ends of the C-shaped bracket 11 to facilitate the support of the tray 7.

[0029] Furthermore, the bottom of the tray 7 is provided with several annular plates 15 at coaxial intervals. The annular plates 15 extend axially, and their bottom ends are higher than the bottom ends of the C-shaped support 11. The annular plates 15 enhance the support strength of the tray 7.

[0030] Preferably, the outermost ring plate 15 is matched with the inner side of the C-shaped support plate 12 to prevent displacement of the tray 7 during rotation.

[0031] Furthermore, the ring plate 15 has two sets of insertion holes 16 spaced apart on the opening side facing the C-shaped support 11, facilitating forklift handling.

[0032] Furthermore, a return gas pipe 17 is provided at the top of the treatment tank 1, and a return gas pipe 13 is provided at the bottom of the treatment tank 1.

[0033] Specifically, return pipe 17 is connected to the carbon dioxide gas tank to realize the circulation of carbon dioxide gas in the tank, and the treated carbon dioxide gas in the tank is recovered and reused through return pipe 2 13.

[0034] Furthermore, a flow-decelerating plate 6 is provided at intervals at the bottom of the processing tank 1 below the fruit-supporting assembly 2 to slow down the injected carbon dioxide gas and prevent the gas from directly impacting the fruit and affecting the fruit processing effect.

[0035] Specifically, the flow-damping plate 6 has several gas channels, and the gas channels are equipped with Tesla valve structures to reduce the gas flow rate.

[0036] In practice, when the fruit undergoes deacidification and deastringency treatment, the rotary actuator 9 drives the fruit-supporting assembly 2 to rotate outside the processing tank 1. Then, a forklift places the fruit-loaded tray 7 onto the fruit-supporting assembly 2. The rotary actuator 9 then drives the fruit-supporting assembly 2 into the processing chamber. At this point, the fruit-supporting assembly 2 is sealed to the window 5, isolating the processing chamber from the external environment. Carbon dioxide gas is then introduced into the processing chamber through the air inlet pipe 3, and simultaneously heated by the carbon dioxide gas in the heater 4. This alters the environmental conditions within the processing chamber, thus performing deacidification and deastringency treatment on the fruit. By adjusting the heating temperature of the heater 4, the device can be adapted to different fruit deacidification and deastringency treatments, improving its adaptability.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
