Abstract
Description
Technical Field
[0001] This application relates to the technical field of food processing equipment, and in particular to an automatic fryer. Background Technology
[0002] Currently, deep fryers are key equipment for processing food using high-temperature oil. They utilize oil temperatures of 160-220℃ to rapidly dehydrate food, forming a crispy outer shell, and are widely used in large-scale production fields such as fast food and ready-to-eat meals. Traditional equipment consists of an oil tank, heating module, filtration system, control unit, and insulation structure. The oil tank is mostly made of stainless steel, with bottom electric heating elements or gas heating devices to control the oil temperature. The filtration system removes residue through an oil pump and filter screen, and the basic control system allows for preset temperature and time parameters. However, existing deep fryers are highly dependent on manual operation. From food loading and turning to finished product retrieval, human intervention is required, leading to low efficiency and inconsistent quality.
[0003] The limitations of manual operation lead to multiple problems. Operators need to frequently stir the ingredients, and each machine requires an average of 1-2 dedicated personnel, with labor costs accounting for more than 35% of total operating costs. Human error causes frying time deviations of ±20 seconds, resulting in oil content fluctuations of more than 3% and significant color differences in the product. At the same time, the risks of high-temperature oil mist and splatter make the workplace injury rate in the frying area twice as high as the industry average, and excessive PM2.5 concentrations threaten the health of operators.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0032] An automatic fryer, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a frying box 100, a frying oven door 200, an oil pan 300, an oil pan electric heater 400, a frying basket 500, a power component 600, a purification component 700, and a fan 800. The frying box 100 has a chamber for installing the oil pan 300, the oil pan electric heater, the frying basket 500, the purification component 700, and the fan 800. The front of the frying box 100 has an opening for the chamber. The frying oven door 200 is rotatably installed at the opening. The feeding port 210 and the discharging port 220 are both located at the frying oven door 200.
[0033] The oil pan 300 is installed at the bottom of the fryer box 100. The oil pan electric heater 400 in this embodiment uses a heating element, but is not limited to this and can also be other heating structures. (See attached diagram.) Figure 3 The front panel of the oil pan 300 is tilted forward from bottom to top, and the bottom of the oil pan 300 is equipped with an oil drain valve 310.
[0034] like Figure 3 and Figure 4 As shown, the frying basket 500 is equipped with a serving tongue 510, which extends upward along the side wall of the frying basket 500 and outward from the opening of the chamber. The serving tongue 510 is equipped with a frying basket 500 rotating shaft connected to the power element 600, and the rotating shaft is detachably installed in the frying box 100. The serving tongue 510, which is higher than the edge of the oil pan 300, is fixed to the frying basket 500 rotating shaft, so that the entire frying basket 500 is supported, fixed, and rotated via the frying basket 500 rotating shaft. To facilitate connection and ensure connection and rotation stability, the bottom surface of the serving tongue 510 that is in close contact with the frying basket 500 rotating shaft is a plane, and the contact surface between the frying basket 500 rotating shaft and the bottom surface of the serving tongue 510 is also a plane, with the two planes tightly attached and fixed.
[0035] The detachable installation structure in this embodiment is as follows: one end of the rotating shaft of the frying basket 500 is round and the other end is square. A rotating shaft bracket 110 is provided on both sides of the frying box 100. One rotating shaft bracket 110 is provided with a hole for inserting the round head, and the other rotating shaft bracket 110 is provided with a slot for the square head to be inserted. The rotating shaft of the power element 600 is provided with a coupling 620 for the square head to be inserted. The coupling 620 is provided with a U-shaped groove that matches the size of the rotating shaft of the frying basket 500.
[0036] like Figure 3 and Figure 5As shown, the upper part of the fryer door 200 is flat, while the lower part has an inwardly sloping surface. The feeding port 210 is located above the side of the frying basket 500, and a flip-up food hopper 211 is embedded in the feeding port 210. Three sides of the food hopper 211 are perpendicular to the bottom plate, and the lower side plate is set at a 30-60 degree angle to the bottom plate. In the closed state, the side plates of the food hopper 211 are embedded in the feeding port 210, and the bottom plate of the food hopper 211 is flush with the panel of the fryer door 200, with the end of the lower side plate located directly above the serving tongue 510.
[0037] The upper end of the food tipping hopper 211 is connected to a handle 212 that can fit snugly against the outside of the fryer door 200. Preferably, the food tipping hopper 211 and the fryer door 200 are magnetically connected for easy pulling. A positioning pin is provided on the food tipping hopper 211 to limit the maximum angle after it flips. Preferably, the food tipping hopper 211 is set to be horizontal after flipping to its maximum angle.
[0038] The discharge port 220 is located on the lower side of the frying basket 500 and on the inclined surface of the lower part of the fryer door 200. An outward-opening door 221 is installed on the discharge port 220. A reset member for keeping the outward-opening door 221 closed is provided between the frying box 100 and the outward-opening door 221. In this embodiment, the reset member can be a tension spring 222 or a torsion spring provided on the interlocking hinge of the outward-opening door 221. In this embodiment, it is set as a tension spring 222, with one end of the tension spring 222 connected to the outward-opening door 221 and the other end connected to the fryer door 200.
[0039] It should be noted that, as Figure 8 As shown, in another embodiment, the reset member can also be a counterweight structure 223 disposed on the outward-opening door 221. The counterweight structure 223 is located on the inner side of the outward-opening door 221 and keeps the outward-opening door 221 closed by gravity.
[0040] After the frying basket 500 flips to the discharge station, the serving tongue 510 tilts downwards and aligns with the discharge port 220. Specifically, the serving tongue 510 is equipped with a pusher 511 for pushing the outward-opening door 221 to open. Before the serving tongue 510 flips to a horizontal position, the pusher 511 contacts the inner wall of the outward-opening door 221. When the serving tongue 510 flips to a horizontal position, the outward-opening door 221 is tilted downwards under the pusher 511. The end of the pusher 511 is arc-shaped, and preferably, a bearing is provided at the end of the pusher 511 that contacts the outward-opening door 221 to avoid damaging the outward-opening door 221 when it is pushed.
[0041] Reference Figure 3 and Figure 4A control cabinet 900 is provided on one side of the frying box 100. The power component 600, the electrical control board 910 and other electrical control cabinet components are all located in the control cabinet 900. The power component 600 is used to control the flipping of the frying basket 500. In this embodiment, the power component 600 includes a drive motor and a motor gearbox. The motor gearbox adopts a double-sided output shaft structure, with one side connected to the frying basket 500 and the other side connected to the limit switch 610.
[0042] Limit switch 610 limits the frying basket 500 to three working angle positions. The first position is the position of the frying basket 500 during frying. In this state, the inclination of the food dispensing tongue 510 is close to the inclination of the front panel of the oil pot 300. The second position is the position where the food is fed into the feeding port 210. At this time, the frying basket 500 is tilted inward by 8-20 degrees. The third angle is the position when the food is poured out. At this time, the fryer tongue is tilted downward by 60-80 degrees.
[0043] like Figure 2 and Figure 5 As shown, the frying tank 100 is equipped with a cold air vent 120 and an exhaust vent 130 at the top. In this embodiment, the cold air vent 120 is located on the inclined surface of the lower part of the fryer door 200, and is used to replenish the low-temperature air inside the frying tank 100 to reduce the temperature of the oil fume gas inside the frying tank 100. However, it should be noted that it can also be located on the side or back of the frying tank 100, or it can be replaced by a door gap between the fryer door 200 and the frying tank 100. In this embodiment, the exhaust vent 130 is located at the top, but it is not limited to this; it can also be located on the side or back of the top of the frying tank 100.
[0044] like Figure 3 As shown, the fryer 100 is equipped with a purification component 700 located above the oil pan 300, and a fan 800 for sending the flue gas passing through the purification component 700 out of the exhaust port 130. The purification component 700 includes a coarse filter 710, a fine filter 720 and a deodorizing filter 730 in sequence along the exhaust direction.
[0045] See Appendix Figure 7 The coarse filter 710 is an interlocking grid that guides the filtered gas through four 90-degree turns. Specifically, it consists of two sets of interlocking U-shaped metal strips.
[0046] See appendix Figure 3 The interlocking mesh is installed at a 6-15° angle inside the frying box 100, and in this embodiment, it is inclined downwards from the front end to the rear end. The frying box 100 is provided with an oil cup 140 for collecting the oil and water filtered by the coarse filter 710. The oil cup 140 is located below the junction of the frying box 100 and the lower end of the coarse filter 710. This design ensures that the oil and water on the coarse filter 710 do not drip into the oil pot 300, and also reduces the space occupied by the frying box 100.
[0047] The fine filter 720 is an electronic purifier or HEPA air filter; the deodorizing filter 730 is preferably an activated carbon filter.
[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
