Description

Technical Field

[0001] This invention relates to the field of feeding technology for fried tofu, specifically to an automatic feeding device for frying equipment used in fried tofu processing. Background Technology

[0002] In the process of food industrialization, frying is an important cooking and flavor-forming process. In the process of frying tofu, the equipment has evolved from intermittent to continuous. Currently, the mainstream equipment is mainly divided into two categories: one is the traditional intermittent fryer, and the other is the modern continuous frying production line.

[0003] Intermittent fryers are typically large, open oil tanks that rely on manual labor or simple tools for feeding, turning, and scooping out ingredients. This method has inherent drawbacks such as high labor intensity, drastic oil temperature fluctuations, large oil consumption, and product quality that depends on worker experience and is inconsistent. While continuous frying production lines offer controllable oil temperature and process, they are often large in size, require a large floor space, and need long cooling channels, making them inconvenient to use and more expensive. Moreover, this method often involves continuous immersion frying rather than true double frying, which can result in differences in flavor. Summary of the Invention

[0018] 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.

[0019] Please see Figures 1-10 The present invention provides a technical solution: an automatic feeding device for frying equipment for frying tofu, including an annular heating box 1, four sets of heat-insulating arc blocks 2 are fixedly installed inside the annular heating box 1, an installation cylinder 3 is rotatably installed at the center of the annular heating box 1, a movable rod 4 is movably inserted inside the installation cylinder 3, a hollow disc 5 is fixedly installed at the upper end of the movable rod 4, hollow rods 6 are fixedly installed in an array on the hollow disc 5, and a loading filter frame 7 is fixedly installed at the lower end of each hollow rod 6; The discharge mechanism 8 includes a discharge filter plate 801, a positioning block 802, and a connecting frame 803. The discharge filter plate 801 is movably inserted into the loading filter frame 7. The positioning block 802 is fixedly installed on the discharge filter plate 801, and the connecting frame 803 is fixedly installed on the positioning block 802. The connecting frame 803 is in contact with the outer side of the loading filter frame 7. The drive mechanism 9 includes a second rotary motor 902 and a second spring 906. The second rotary motor 902 is fixedly installed inside the annular heating box 1. The second spring 906 is sleeved on the movable rod 4. One end of the second spring 906 abuts against the inner side of the mounting cylinder 3. The cleaning mechanism 10 includes a third ventilation slot 1010 and a threaded pipe 1011. The annular heating box 1 has a third ventilation slot 1010, and a threaded pipe 1011 is fixedly installed on one side of the third ventilation slot 1010.

[0020] The annular heating box 1 is an annular heating device consisting of a base, an inner ring, an outer ring, and heating components. Edible oil is placed in the grooves between the heat-insulating arc blocks 2, and heating components are installed on the lower side of the corresponding grooves for heating. The annular heating box 1 is divided into four temperature zones by four sets of heat-insulating arc blocks 2. With the addition of a rotating and lifting loading filter frame 7, the automatic frying and refrying of tofu is realized. Furthermore, the rotation of the loading filter frame 7 can continuously remove residue from the hot oil in the annular heating box 1. Each time the loading filter frame 7 is raised, cooling and oil draining can be carried out, which not only allows the tofu to cool down quickly but also reduces the temperature fluctuations caused by cross-contamination of edible oil in different temperature zones.

[0021] Furthermore, the discharge mechanism 8 also includes a connecting folding cylinder 804, a positioning groove 805, and a stop block 806. Positioning grooves 805 are provided on both sides of the loading filter frame 7, and the positioning block 802 is engaged within the positioning grooves 805. The connecting folding cylinder 804 is fixedly installed on the upper side of the connecting frame 803. The shape of the connecting folding cylinder 804 matches the shape of the hollow rod 6. The connecting folding cylinder 804 is movably sleeved on the hollow rod 6. The stop block 806 is fixedly installed at the upper end of the connecting folding cylinder 804. The upper and lower ends of the discharge filter plate 801 do not contact the inner side of the loading filter frame 7, and the height of the loading filter frame 7 matches the height of the heat-insulating arc-shaped block 2. This structure is the connection structure for the discharge filter plate 801. Structurally, moving the connecting folding cylinder 804 can move the discharge filter plate 801. The shape of the discharge filter plate 801 not only allows the tofu in the loading filter frame 7 to be layered, but also allows the tofu to be completely removed during the movement of the discharge filter plate 801, making the loading and placement of tofu more convenient. Furthermore, the discharge mechanism 8 also includes a fixed bracket 807, a mounting groove 808, a movable push rod 809, a first guide rod 810, a first guide groove 811, a first rack 812, a first rotary motor 813, and a first gear 814. A fixed bracket 807 is fixedly installed on the annular heating box 1. The upper end of the fixed bracket 807 is located on the upper side of the hollow disc 5. A mounting groove 808 is formed at the center of the upper end of the fixed bracket 807. Two sets of movable push rods 809 are movably inserted into the mounting groove 808, with one end of each movable push rod 809 fixedly mounted on the mounting groove. The first guide rod 810 is installed, and the movable push rod 809 has a first guide groove 811. The first guide rod 810 is inserted into the first guide groove 811 on another set of movable push rods 809. The first rack 812 is fixedly installed on both sets of movable push rods 809. The upper end of the fixed bracket 807 is fixedly installed with a first rotary motor 813. The output shaft of the first rotary motor 813 is fixedly installed with a first gear 814. The first gear 814 meshes with both sets of first racks 812. The end of the movable push rod 809 contacts the stop block 806. This structure is a counter-drive structure for the movable push rod 809. Its purpose is to drive the discharge filter plate 801 to move by abutting against the abutment block 806. The characteristic is that the movable push rod 809 and the abutment block 806 are not structurally connected, so the movable push rod 809 can only push the abutment blocks 806 on the front and rear sides. Secondly, in terms of structure, the first rack 812 is set on the upper side to extend the movement process of the movable push rod 809 and increase the applicability of the equipment. This drive structure is not only the discharge structure of the discharge filter plate 801, but also the oil sludge discharge structure for subsequent oil sludge cleaning. Furthermore, the discharge mechanism 8 also includes a second guide rod 815, a first spring 816, a second guide groove 817, and a shielding plate 818. Two sets of second guide rods 815 are fixedly installed on the hollow rod 6, and two sets of second guide grooves 817 are opened on the connecting folding cylinder 804. The second guide rods 815 are movably inserted into the second guide grooves 817. The first spring 816 is sleeved on the second guide rod 815 and abuts against the inner side of the second guide groove 817. Two sets of shielding plates 818 are fixedly installed on the left and right sides of the annular heating box 1. The shape and width of the shielding plates 818 are adapted to the shape and width of the loading filter frame 7. This structure is a reset structure for the discharge filter plate 801. The first spring 816 resets the filter plate 801. When the movable push rod 809 retracts, the stop block 806 retracts along with the movable push rod 809, thereby resetting the discharge filter plate 801 without affecting the normal rotation of the loading filter frame 7. The shielding plate 818 is there so that when the loading filter frame 7 is placed on the heat-insulating arc blocks 2 on the left and right sides for wind-powered oil draining, the tofu will not move unnecessarily due to the wind. At the same time, it concentrates the wind and increases the oil draining efficiency. Furthermore, the drive mechanism 9 also includes a ring rack 901, a second gear 903, a cross guide block 904, and a cross guide groove 905. The ring rack 901 is fixedly installed on the lower side of the mounting cylinder 3, and the second gear 903 is fixedly installed on the output shaft of the second rotary motor 902. The second gear 903 meshes with the ring rack 901. The cross guide block 904 is fixedly installed inside the mounting cylinder 3, and the cross guide groove 905 is opened inside the movable rod 4. The cross guide block 904 is movably inserted into the cross guide groove 905. This structure is the drive structure for rotating the loading filter frame 7, and it allows the hollow disc 5 to move vertically, thereby enabling the loading filter frame 7 to perform a cycle of immersion in oil for frying, rising to drain oil and cool, realizing the frying, detachment, and refrying process. Compared with general conveyor belt frying equipment, this motion form also has the characteristics of small footprint, less oil consumption, and precise oil temperature control. Furthermore, the drive mechanism 9 also includes a guide column 907, a guide ring 908, and an arc-shaped guide block 909. Four sets of arc-shaped guide blocks 909 are fixedly installed on the inner ring of the annular heating box 1. The shape and position of the arc-shaped guide blocks 909 are opposite to the shape and position of the heat-insulating arc-shaped block 2. A guide column 907 is fixedly installed on the lower side of the hollow rod 6. A guide ring 908 is rotatably installed on the guide column 907. The guide ring 908 abuts against the upper side of the arc-shaped guide block 909. This structure is a guide structure in the vertical direction of the loading filter frame 7. By utilizing the extension and retraction of the movable rod 4 and the guidance of the arc-shaped guide block 909, the loading filter frame 7 can move along the shape of the combination of the annular heating box 1 and the heat-insulating arc-shaped block 2, which also provides conditions for the subsequent filtration of oil sludge. Furthermore, the cleaning mechanism 10 also includes a storage tank 1001, a guide inclined block 1002, a discharge hole 1003, and an oil residue filter plate 1006. The storage tank 1001 is provided on the heat-insulating arc-shaped block 2, and the guide inclined block 1002 is fixedly installed inside the storage tank 1001. Four sets of discharge holes 1003 are provided on the outer ring of the annular heating box 1. The positions of the discharge holes 1003 and the guide inclined blocks 1002 are matched. The oil residue filter plate 1006 is fixedly installed on the connecting frame 803, and the oil residue filter plate 1006 does not adhere to the outer side of the loading filter frame 7. This structure allows the oil residue in the hot oil to be scooped up through the oil residue filter plate 1006 during the movement of the loading filter frame 7. When it moves to the heat-insulating arc-shaped block 2, the oil residue can be discharged along the storage tank 1001 onto the guide inclined block 1002, and then discharged from the discharge hole 1003, achieving continuous discharge of oil residue from the hot oil and increasing the functionality of the equipment during use. Furthermore, the cleaning mechanism 10 also includes an elliptical hollow ring 1004 and connecting pipes 1005. The rear discharge port 1003 is higher than the side discharge ports 1003, and the side discharge ports 1003 are higher than the front discharge port 1003. An elliptical hollow ring 1004 is fixedly installed on the outside of the annular heating box 1. Four sets of connecting pipes 1005 are fixedly installed on the elliptical hollow ring 1004, and the connecting pipes 1005 are connected to the discharge ports 1003. The front connecting pipe 1005 is connected to the outside. This structure allows the oil residue and leached oil to be discharged in a centralized manner. Combined with the subsequent ventilation structure, the oil residue and waste oil can be discharged smoothly, increasing the stability and controllability of the equipment during use. Furthermore, the cleaning mechanism 10 also includes a disc base 1007, a first ventilation slot 1008, and a second ventilation slot 1009. The disc base 1007 is fixedly installed on the lower side of the mounting cylinder 3. The disc base 1007 is rotatably mounted on the annular heating box 1. The disc base 1007 and the cross guide block 904 are both provided with the first ventilation slot 1008. The movable rod 4 is provided with the second ventilation slot 1009, which is connected to the hollow disc 5. The position of the end of the third ventilation slot 1010 is adapted to the position of the first ventilation slot 1008 on the disc base 1007. The threaded pipe 1011 is connected to an external fan. This structure allows the loading filter frame 7 to be cooled by ventilation when it moves onto the heat-insulating arc block 2. This method can not only cool the tofu but also drain the oil from the loading filter frame 7 itself and the tofu, increasing the functionality and stability of the equipment during use. Furthermore, the cleaning mechanism 10 also includes an oil sludge scraper 1012, a guide ramp 1013, and side plates 1014. The oil sludge scraper 1012 is fixedly installed on the front and rear sides of the outer ring of the annular heating box 1. The height of the oil sludge scraper 1012 is adapted to the height of the oil sludge filter plate 1006. The position of the oil sludge filter plate 1006 is adapted to the position of the storage tank 1001. The guide ramp 1013 is fixedly installed on the front and rear sides of the annular heating box 1. The guide ramp 1013 is located on one side of the oil sludge scraper 1012. Two sets of side plates 1014 are fixedly installed on the guide ramp 1013. The thickness of the side plates 1014 is adapted to the distance between the loading filter frame 7 and the oil sludge filter plate 1006. The position of the oil residue filter plate 1006 is adapted to the rotation direction of the loading filter frame 7. When the oil residue filter plate 1006 rotates to the position opposite to the oil residue scraper 1012, the connecting frame 803 is pushed out by the action of the movable push rod 809. The edge of the oil residue filter plate 1006 abuts against the edge of the oil residue scraper 1012, and the oil residue attached to the oil residue filter plate 1006 is scraped off and enters the storage tank 1001. When the discharge filter plate 801 is pushed out, the tofu will also be discharged along the guide inclined plate 1013. Then, the tofu can be manually picked up and placed.

[0022] Working Principle: In use, tofu is placed in the loading filter frame 7 and on the discharge filter plate 801. The second rotary motor 902 is started, causing the second gear 903 to rotate. Through meshing with the ring rack 901, the mounting cylinder 3 rotates, thereby driving the movable rod 4, the hollow disc 5, and the hollow rod 6 to rotate, which in turn causes the loading filter frame 7 to rotate. During the rotation, the guide ring 908 rotates against the arc-shaped guide block 909 and, guided by the arc-shaped guide block 909, descends under the action of the second spring 906, immersing the loading filter frame 7 in the low-temperature oil zone for shaping and frying. After frying, the mounting cylinder 3 continues to rotate, driving the loading filter frame 7 to rotate, guided by the arc-shaped guide block 909. The loading filter frame 7 is placed on the heat-insulating arc block 2. At this time, the shielding plate 818 shields the loading filter frame 7. The fan is started, and the air passes through the third ventilation slot 1010, the first ventilation slot 1008, the second ventilation slot 1009, the hollow disc 5, and finally exits from the hollow rod 6 to cool and drain the oil from the loading filter frame 7 and the tofu. Before rotating to the heat-insulating arc block 2, the oil residue filter plate 1006 pushes the oil residue into the storage tank 1001. During the air cooling process, the drained oil and oil residue enter the elliptical hollow ring 1004 under the action of the air and finally exit from the front connecting pipe 1005. Then the loading filter frame 7 rotates to the high-temperature oil zone for re-frying and finally gradually moves to the rear heat-insulating arc block 2.

[0023] Before rotating onto the rear heat-insulating arc block 2 and fully engaging with it, the loading filter frame 7 will first rotate to face the oil residue scraper 1012, start the first rotary motor 813, drive the first gear 814 to rotate, and through meshing with the first rack 812, drive the movable push rod 809 to move away from each other, so that the movable push rod 809 abuts against the stop block 806, causing the connecting folding cylinder 804, the connecting clamp frame 803 and the discharge filter plate 801 to move. The discharge filter plate 801 pushes the tofu to discharge the fried tofu. During the movement, the oil residue filter plate 1006 moves synchronously, so that the oil residue on the oil residue filter plate 1006 is scraped off by the oil residue scraper 1012. At this time, the oil residue is discharged into the storage tank 1001 and then discharged. After placing new tofu, the cycle continues.
