Abstract

This invention discloses a poultry fryer, comprising a fryer body, a receiving rack, a controller, an upper cover, a split cover, a transmission chain mechanism, a drive motor, a frying frame, a first circulation pipe, a filter, a second circulation pipe, a circulation pump, a third circulation pipe, an electric heater, and a temperature sensor. This invention also discloses a processing method for the poultry fryer. Through the above method, this invention utilizes a circulation pump to drive the frying oil through a filter for circulation filtration, effectively removing food residue and meat fragments from the frying oil, promptly filtering out impurities, and preventing them from burning into porous carbon particles at high temperatures. This cuts off the catalyst source that accelerates oil deterioration, effectively inhibiting the chain reaction of deterioration reactions such as increased acid value, darker color, increased viscosity, and off-odors, significantly extending the service life of the frying oil, reducing oil change costs, and simultaneously enabling automatic unloading of the frying frame, resulting in relatively low labor costs.

Description

Technical Field

[0001] This invention relates to the field of poultry processing technology, specifically to a poultry frying machine and its processing method. Background Technology

[0002] Deep-frying is a widely used cooking method in the industrial production of poultry products. During continuous deep-frying, the coating, batter, and meat scraps adhering to the surface of the poultry raw materials continuously detach and enter the hot oil. These suspended solid impurities carbonize under the continuous high temperature environment, forming charred particles. Because carbonized particles have extremely strong catalytic activity, they significantly accelerate the oxidative rancidity and polymerization reactions of the oil, causing the frying oil to increase in acid value, darken in color, increase in viscosity, and produce off-flavors in a very short time.

[0003] Currently, most conventional equipment used for poultry frying consists of a single frying tank, heating element, and conveying mechanism. Such equipment generally lacks a filtration system for real-time circulation and purification of the frying oil. Due to the lack of a dedicated filtration system, fine impurities and carbonized residues generated during frying remain trapped in the oil tank. These impurities continue to catalyze the oxidation and rancidity of the oil at high temperatures, forcing producers to frequently replace the entire batch of oil to maintain its usability. This not only significantly increases raw material costs but also makes cleaning the stubborn grease deposits at the bottom of the tank difficult, further burdening equipment maintenance and impacting continuous production efficiency.

[0015] Compared with the prior art, the present invention provides a poultry frying machine and its processing method, which has the following beneficial effects: 1. This invention utilizes a circulating pump to drive frying oil through a circulating filtration loop consisting of a filter, a first circulating pipe, a second circulating pipe, and a third circulating pipe. This continuously purifies the frying oil during the fryer's operation, creating a continuous frying and filtering working mode. The circulating pump provides stable circulation power, continuously drawing hot oil mixed with food residue and meat scraps from the receiving cavity and transporting it to the filter. After the filter traps impurities, the clean oil flows back to the receiving cavity through the circulating pipes to continue frying. This design can separate food residue and meat scraps from the high-temperature oil in a very short time as they detach. This invention removes impurities to prevent them from accumulating and carbonizing into charred, porous carbon particles under prolonged high temperatures. Once formed, these carbon particles become catalytic centers that accelerate the oxidation and rancidity of oils, leading to a chain reaction of deterioration, such as increased acid value, darker color, increased viscosity, and off-odors. By filtering out impurities at the source, this invention cuts off the path of carbon particle formation and accumulation, effectively inhibiting the occurrence of the above-mentioned chain reaction of deterioration. This allows frying oil to maintain relatively stable performance under long-term continuous operation, significantly extending the service life of frying oil and reducing the frequency of oil changes and oil costs. 2. The transmission chain mechanism can realize automatic unloading of the frying box, eliminating the need for manual unloading and reducing labor costs; 3. The rotating design of the upper cover and the split cover allows operators to directly access the inner wall of the receiving cavity without disassembling any parts, enabling rapid rinsing, scraping off grease and dirt, and routine maintenance. It features simple operation, high flexibility, and relatively high cleaning efficiency. Attached Figure Description

Detailed Implementation

[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] like Figure 1-20 As shown, the present invention provides a poultry fryer, including a fryer body 1, a receiving rack 13, a controller 12, an upper cover 2, a split cover 23, a transmission chain mechanism 3, a drive motor 14, a frying frame 4, a first circulation pipe 51, a filter 52, a second circulation pipe 53, a circulation pump 54, a third circulation pipe 55, an electric heater 111, and a temperature sensor 112.

[0020] The top surface of the fryer body 1 is recessed downwards to form a receiving cavity 11, wherein a receiving rack 13 is provided at one end of the fryer body 1. It should be understood that the receiving cavity 11 is used to contain frying oil, providing the oil environment required for frying poultry. The receiving rack 13 is located at the discharge end of the fryer body 1 and is used to receive the finished product that has been fried and automatically falls from the frying frame 4.

[0021] Preferably, the receiving rack 13 is disposed at one end of the receiving cavity 11 of the fryer body 1 and below the discharge port 24, wherein the receiving rack 13 includes a receiving groove 131 and a filter baffle 132 disposed in the receiving groove 131.

[0022] It should be understood that the position design of the receiving shelf 13 ensures that the material can fall accurately after leaving the delivery port 24; the receiving trough 131 is used to collect finished products in a centralized manner, while the filter baffle 132 can filter out excess oil droplets attached to the surface of the material in real time during the collection process, maintaining the crispy texture of the finished product.

[0023] The controller 12 is located in the fryer body 1. It should be understood that the controller 12, as the control center of the fryer body 1, is used to receive the oil temperature signal fed back by the temperature sensor 112, and control the start and stop of the electric heater 111, the speed and start and stop of the drive motor 14, and the working state of the circulation pump 54 according to the preset program, so as to realize the integrated automatic control of frying temperature, frying frame rotation speed and oil circulation filtration.

[0024] One end of the upper cover 2 is rotatably disposed on the top surface of the fryer body 1. The upper cover 2 protrudes upward and forms a receiving space 21 that forms a frying space with the receiving cavity 11. One end of the upper cover 2 is provided with a feeding port 22. A cover 23 for covering the feeding port 22 is rotatably disposed in one end of the feeding port 22. The other end of the upper cover 2 is provided with a discharging port 24 corresponding to the receiving shelf 13.

[0025] It should be understood that the upper cover 2 is rotatably connected to the fryer body 1 at one end, allowing it to be flipped open upwards for easy cleaning and maintenance of the receiving cavity 11 and its internal components. The receiving space 21 inside the upper cover 2 and the receiving cavity 11 of the fryer body 1 are interlocked vertically to form a closed frying space, effectively reducing hot oil splashing and heat loss. The feeding port 22 is used by operators to feed poultry to be fried. The cover 23 covers the feeding port 22 during non-feeding periods, serving to keep it warm and prevent splashing. The discharging port 24 corresponds to the position of the receiving shelf 13, allowing the frying frame 4, which carries fried products, to automatically unload the material when it reaches this position.

[0026] The transmission chain mechanism 3 is located within the frying space, and includes a rotating chain 353. It should be understood that the transmission chain mechanism 3, as the core of the conveying system, has its chain 353 cyclically rotating along a preset trajectory within the frying space to drive the frying frames 4, which are installed at intervals thereon, through the inlet 22, the frying area, and the outlet 24 in sequence.

[0027] The drive motor 14 is electrically connected to the controller 12, located outside the upper cover 2, and connected to the transmission chain mechanism 3, so as to drive the chain 353 to rotate. It should be understood that the drive motor 14 is driven by the controller 12 and provides a power source for the transmission chain mechanism 3. By placing the drive motor 14 outside the upper cover 2, it can avoid direct exposure to the high-temperature oil vapor environment, extend the service life of the motor, and improve operational safety.

[0028] Multiple frying crates 4 for holding poultry are spaced apart on a chain 353 to rotate synchronously with the chain 353. It should be understood that each frying crate 4 holds a portion of poultry to be fried, and in the process of rotating synchronously with the chain 353, the processes of loading, deep-frying, draining and unloading are completed in sequence to achieve continuous batch production.

[0029] One end of the first circulation pipe 51 is connected to the output port of the receiving cavity 11 of the fryer body 1. It should be understood that the first circulation pipe 51 draws out all the hot oil (containing food residue and debris, etc.) in the receiving cavity 11 and delivers it to the filter 52 for filtration.

[0030] A filter 52 is disposed at one end of the fryer body 1, wherein the inlet of the filter 52 is connected to the other end of the first circulation pipe 51. It should be understood that the filter 52 receives hot oil from the first circulation pipe 51 and uses its internal filter element or filter screen to trap food residue, shredded meat, and meat particles in the oil, preventing impurities from carbonizing due to prolonged residence in the high-temperature oil.

[0031] One end of the second circulation pipe 53 is connected to the output port of the filter 52. It should be understood that the second circulation pipe 53 leads the hot oil purified by the filter 52 to the suction port of the circulation pump 54 in preparation for the next stage of pumping.

[0032] The circulation pump 54 is electrically connected to the controller 12 and is located below the filter 52, with its inlet connected to the other end of the second circulation pipe 53. It should be understood that the circulation pump 54 operates under the command of the controller 12, providing power for the flow of frying oil in the circulating filter loop.

[0033] One end of the third circulation pipe 55 is connected to the output port of the circulation pump 54, and the other end of the third circulation pipe 55 is connected to the input port of the receiving cavity 11 of the fryer body 1. It should be understood that the third circulation pipe 55 sends the clean hot oil, which has been pressurized by the circulation pump 54 and purified by the filter 52, back to the receiving cavity 11 of the fryer body 1 to complete one complete filtration cycle.

[0034] In this embodiment, an electric heater 111 and a temperature sensor 112, both electrically connected to the controller 12, are installed inside the receiving cavity 11. It should be understood that the electric heater 111 is responsible for heating the frying oil inside the receiving cavity 11, maintaining the oil temperature within a set frying temperature range. The temperature sensor 112 detects the oil temperature in real time and feeds the signal back to the controller 12. The controller 12 switches the electric heater 111 on and off based on the deviation between the set value and the measured value.

[0035] Preferably, the receiving cavity 11 is arc-shaped, and the bottom wall of the receiving cavity 11 is provided with a receiving groove 113. A filter screen 114 is provided between the receiving cavity 11 and the receiving groove 113. One end of the first circulation pipe 51 is connected to the output port of the receiving groove 113 of the fryer body 1, and the other end of the third circulation pipe 55 is connected to the input port of the receiving cavity 11 of the fryer body 1.

[0036] It should be understood that the arc-shaped receiving cavity 11 facilitates the concentration of hot oil and residue towards the low-lying area at the bottom under gravity. The receiving groove 113 on the bottom wall forms a low-level residue collection area. The filter screen 114 between the receiving cavity 11 and the receiving groove 113 serves as the first coarse filtration barrier, which can pre-intercept larger impurities (such as those removed manually) and prevent them from entering the circulation pipeline (preventing pipeline blockage), thereby reducing the processing load on the subsequent filter 52 and extending the service life and maintenance cycle of the filter 52. The first circulation pipe 51 draws oil with a high residue concentration from the bottom of the receiving groove 113 for centralized filtration, and the third circulation pipe 55 returns the clean oil to the upper area of ​​the receiving cavity 11, forming a directional oil flow that is conducive to the sedimentation and collection of impurities.

[0037] Preferably, the outer wall of the receiving groove 113 is coated with a heat insulation layer 1131, the electric heater 111 is disposed in the receiving groove 113, and the temperature sensor 112 is disposed in the receiving cavity 11.

[0038] It should be understood that the insulation layer 1131 on the outer wall of the receiving groove 113 can effectively reduce heat loss and reduce equipment energy consumption. The temperature sensor 112 is installed inside the receiving cavity 11 to measure the actual oil temperature in the frying area, providing accurate feedback for the temperature control of the controller 12.

[0039] In this embodiment, the frying frame 4 includes a movable plate 41 with a rotating configuration. It should be understood that the movable plate 41 is the core component of the automatic unloading system. When the frying frame 4 moves to the outlet 24 position, the movable plate 41 automatically flips downward and opens under the combined action of its own gravity and the gravity of the material (or food), allowing the fried material to slide down to the receiving shelf 13. There is no need for manual tipping or machine stopping, which improves efficiency and avoids material damage.

[0040] Specifically, the frying frame 4 includes a bottom plate 42, a first side plate 43, a second side plate 44, a rear side plate 45, and a movable plate 41.

[0041] The bottom plate 42 is mounted on the chain 353. It should be understood that the bottom plate 42 serves as the load-bearing base of the frying frame 4, and is directly fixed to the chain 353 connector. It is responsible for bearing the weight of the materials and driving the frying frame 4 to move synchronously with the transmission chain mechanism 3.

[0042] The first side plate 43 is located at one end of the bottom plate 42. It should be understood that the first side plate 43 cooperates with the second side plate 44 to form left and right limits, preventing materials from falling from the side during the operation of the chain 353 or during frying and tumbling.

[0043] The second side plate 44 is located at the other end of the bottom plate 42. It should be understood that the second side plate 44 cooperates with the first side plate 43 to form left and right limits, preventing materials from falling from the side during the operation of the chain 353 or during frying and tumbling.

[0044] The rear side plate 45 is located at the rear end of the bottom plate 42. It should be understood that the rear side plate 45 closes the rear of the frying frame 4 to prevent the material from sliding backward when moving upward or horizontally with the chain 353.

[0045] The movable plate 41 is rotatably mounted at the bottom of the front side of the bottom plate 42.

[0046] Preferably, the bottom plate 42, the rear side plate 45, the first side plate 43, the second side plate 44, and the movable plate 41 form a frying cavity 40. It should be understood that the frying cavity 40 is used to hold the material to be fryed, and the movable plate 41 serves as the front door of the cavity. It is normally closed to lock the material, and opens to release the material when it reaches the unloading point. This structural design realizes the integrated function of "loading-transporting-frying-automatic unloading".

[0047] Preferably, the bottom plate 42, rear side plate 45, first side plate 43, second side plate 44, and movable plate 41 are all provided with multiple mesh holes. It should be understood that the mesh hole design has a triple function: first, it allows high-temperature oil to pass freely through the frying frame 4, so that the material is in full contact with the oil and ensures uniform frying; second, it reduces the oil resistance during the operation of the frying frame 4, reduces the load on the drive motor 14, and also has a filtering effect, preventing debris or large particles in the frying frame 4 from falling into the receiving cavity 11; third, during the unloading and oil draining stages, it helps excess oil to flow back into the receiving cavity 11 quickly, reducing the oil content of the finished product.

[0048] Furthermore, the length of the movable plate 41 is greater than the distance between the first side plate 43 and the second side plate 44, wherein the bottom end of the movable plate 41 extends to provide an extension plate 46 located between the first side plate 43 and the second side plate 44, and the extension plate 46 is rotatably disposed between the bottom end of the first side plate 43 and the bottom end of the second side plate 44.

[0049] It should be understood that the length of the movable plate 41 is designed to completely cover the front opening when the frying frame 4 is in the closed state (i.e., the movable plate 41 is positioned between the first side plate 43 and the second side plate 44), while not intruding into the frying cavity 40 of the frying frame 4, effectively preventing small materials from leaking out. The extension plate 46 is used to rotatably connect the movable plate 41 between the first side plate 43 and the second side plate 44, providing a stable fulcrum for the movable plate 41 and ensuring that the movable plate 41 moves smoothly during opening and closing.

[0050] Specifically, the end of the extension plate 46 away from the movable plate 41 is bent to form a through hole 461, the bottom end of the first side plate 43 is provided with a first through hole 431, and the bottom end of the second side plate 44 is provided with a second through hole 441, wherein the first through hole 431, the through hole 461 and the second through hole 441 are through which a rotating shaft passes.

[0051] It should be understood that the first through hole 431 and the second through hole 441 are respectively located at the bottom of the first side plate 43 and the second side plate 44, so that when the extension plate 46 rotates around the pivot, it drives the movable plate 41 to open and close at the front end of the frying frame 4, thereby realizing the switching of the opening and closing state of the frying frame 4.

[0056] The support crossbar 313 is disposed between the first support plate 311 and the second support plate 312. It should be understood that the support crossbar 313 enhances the connection strength between the first support plate 311 and the second support plate 312, prevents the first support plate 311 and the second support plate 312 from opening outward or contracting inward, and provides a guide reference for the lifting and lowering movement of the adjusting rod 34.

[0057] The support platform 32 is located between the bottom of the first support plate 311 and the bottom of the second support plate 312. It should be understood that the support platform 32 is located below the support crossbar 313 and is fixedly connected to the bottom of the first support plate 311 and the second support plate 312. It serves as the mounting base for the second rotating rod 3512 and the third rotating rod 3513, providing a stable mounting position for the second rotating rod 3512 and the third rotating rod 3513, ensuring the positioning accuracy of the lower sprocket assembly, thereby ensuring that the chain 353 forms a stable transmission path at the bottom, and preventing the chain 353 from running off-center or interfering with the bottom of the equipment due to loose mounting base.

[0058] The adjusting plate 33 is located at the top of the first support plate 311. It should be understood that the adjusting plate 33 provides a vertically movable support point for one end of the first rotating rod 3511. The height of this end is finely adjusted through the internal adjusting mechanism 36, thereby changing the center distance between the first rotating rod 3511 and the lower rotating rod, so as to achieve the purpose of fine-tuning the tightness.

[0059] The adjusting rod 34 is set vertically on the end of the supporting crossbar 313 away from the first supporting plate 311. It should be understood that the adjusting rod 34 is threadedly connected to the supporting crossbar 313. By rotating the adjusting rod 34, the height of the adjusting rod 34 can be changed.

[0060] The first rotating rod 3511 is rotatably disposed within the receiving space 21 of the upper cover 2. The first rotating rod 3511 is height-adjustable within the receiving space 21 via an adjustment mechanism, and the rotating shaft of the drive motor 14 is connected to the first rotating rod 3511, thereby driving the first rotating rod 3511 to rotate. Furthermore, the first rotating rod 3511 is rotatably disposed on the adjustment plate 33 and the adjustment rod 34. It should be understood that the adjustment plate 33 and the adjustment rod 34 form the structure of the adjustment mechanism, enabling the lifting and lowering of the first rotating rod 3511.

[0061] The first gear 3521 and the second gear 3522 are spaced apart at both ends of the first rotating rod 3511.

[0062] It should be understood that the first rotating rod 3511 is the active rod of the conveying structure. The first rotating rod 3511 is driven to rotate by the drive motor 14, that is, the first chain 3531 and the second chain 3532 are driven to rotate by the first gear 3521 and the second gear 3522. At the same time, the height of the first rotating rod 3511 can be changed by adjusting the adjusting plate 33 and the adjusting rod 34.

[0063] The second rotating rod 3512 and the third rotating rod 3513 are rotatably arranged in the receiving cavity 11 of the fryer body 1 in a horizontal direction. Furthermore, the second rotating rod 3512 and the third rotating rod 3513 are located below the first rotating rod 3511. The second rotating rod 3512 is rotatably arranged at one end of the support platform 32, and the third rotating rod 3513 is rotatably arranged at the other end of the support platform 32. The two ends of the second rotating rod 3512 are respectively provided with a third gear 3523 and a fourth gear 3524, and the two ends of the third rotating rod 3513 are respectively provided with a fifth gear 3525 and a sixth gear 3526.

They are rotatably mounted at both ends of the support platform 32, and provide support and guidance for the first chain 3531 and the second chain 3532 through the third gear 3523, the fourth gear 3524, the fifth gear 3525, and the sixth gear 3526.

[0065] The first chain 3531 is arranged around the first gear 3521, the third gear 3523 and the fifth gear 3525.

[0066] The second chain 3532 is arranged around the second gear 3522, the fourth gear 3524, and the sixth gear 3526. It should be understood that the first chain 3531 and the second chain 3532 rotate synchronously.

[0067] Preferably, the two ends of the bottom plate 42 of the frying frame 4 are respectively set in the first chain 3531 and the second chain 3532 through the first connector and the second connector, so that the frying frame 4 rotates synchronously with the first chain 3531 and the second chain 3532.

[0068] In this embodiment, the adjusting rod 34 is vertically and vertically mounted on the supporting crossbar 313, and the adjusting plate 33 is provided with an adjusting mechanism 36 for adjusting the lifting and lowering of one end of the first rotating rod 3511.

[0069] It should be understood that by adjusting the height of both ends of the first rotating rod 3511 through the adjusting rod 34 and the adjusting mechanism 36, the center distance between the first rotating rod 3511 and the lower rotating rod is changed, thereby achieving the purpose of adjusting the tension of the chain 353.

[0070] Preferably, the adjusting plate 33 is provided with an elongated adjusting groove 337 along the vertical direction, and the adjusting mechanism 36 includes a lifting plate 361 slidably disposed within the adjusting groove 337, wherein one end of the first rotating rod 3511 passes through the adjusting groove 337 and is connected to the lifting plate 361. It should be understood that the height of one end of the first rotating rod 3511 is adjusted by sliding the lifting plate 361 up and down.

[0071] Specifically, the adjusting plate 33 has a first bending block 331 and a second bending block 332 bent at both ends. The first bending block 331 forms a first sliding groove 333 vertically aligned with one side of the adjusting plate 33, and the second bending block 332 forms a second sliding groove 334 vertically aligned with the other side of the adjusting plate 33. The lifting plate 361 has a first sliding part 3611 within the first sliding groove 333 and a second sliding part 3612 within the second sliding groove 334 at both ends. It should be understood that the lifting plate 361 is slidably connected to the adjusting plate 33 via the first sliding part 3611 and the second sliding part 3612, thereby achieving vertical displacement.

[0072] Furthermore, the top of the adjusting plate 33 is bent with a third bending block 335, and the third bending block 335 is provided with a first through hole 336. The top of the lifting plate 361 is bent with a fourth bending block 3613, and the fourth bending block 3613 is provided with a second through hole 3614 corresponding to the first through hole 336. The adjusting mechanism 36 also includes a first screw 362 and a first nut 363. The first nut 363 is provided on the third bending block 335. The screw body of the first screw 362 passes through the second through hole 3614 and the first through hole 336 and is threadedly connected to the first nut 363. The nut of the first screw 362 is locked on the bottom surface of the fourth bending block 3613.

[0073] It should be understood that since the adjusting plate 33 is fixed by the first support plate 311, the first nut 363 is threadedly connected to the first screw 362. By rotating the first nut 363, the first screw 362 is moved in the vertical direction, and the nut of the first screw 362 is locked on the bottom surface of the fourth bending block 3613. The first screw 362 drives the lifting plate 361 to move synchronously, thereby realizing the adjustment of the height of one end of the first rotating rod 3511.

[0074] Preferably, the top end of the adjusting rod 34 is provided with a first bearing seat 371, and a first bearing 3711 is provided inside the first bearing seat 371. The other end of the first rotating rod 3511 passes through the first bearing 3711. It should be understood that the first bearing 3711 can reduce friction and improve transmission efficiency.

[0075] In this embodiment, a second nut 341 is provided at the end of the support crossbar 313 away from the first support plate 311, and an adjusting rod 34 passes through the bearing platform 32, the support crossbar 313 and the second nut 341, and the adjusting rod 34 is provided with an external thread 340 that is threadedly connected to the second nut 341.

[0076] It should be understood that the second nut 341 is fixedly mounted on the support crossbar 313, and the adjusting rod 34 is threadedly connected to the second nut 341. Since the bearing platform 32 and the support crossbar 313 are fixedly mounted between the first support plate 311 and the second support plate 312, the vertical displacement of the adjusting rod 34 can be achieved by rotating the adjusting rod 34 (such as manual fine adjustment). At the same time, the self-locking characteristic of the thread ensures that the position of the adjusting rod 34 will not be changed by gravity.

[0077] Furthermore, a second bearing seat 372 and a third bearing seat 373 are spaced apart at one end of the support platform 32. The second bearing seat 372 houses a second bearing 3721, and the third bearing seat 373 houses a third bearing 3731. A second rotating rod 3512 passes through the second bearing 3721 and the third bearing 3731.

The fourth bearing seat 374 houses a fourth bearing 3741, and the fifth bearing seat 375 houses a fifth bearing 3751. A third rotating rod 3513 passes through the fourth bearing 3741 and the fifth bearing 3751.

[0078] It should be understood that the second rotating rod 3512 is mounted at one end of the support platform 32 via the second bearing seat 372 and the third bearing seat 373, and the third rotating rod 3513 is mounted at the other end of the support platform 32 via the fourth bearing seat 374 and the fifth bearing seat 375, forming a stable support structure that keeps the positions of the second rotating rod 3512 and the third rotating rod 3513 fixed during operation, ensuring the stable operation of the conveying structure.

[0079] Specifically, the first chain 3531 is provided with a first connector 381 for connecting to one end of the frying frame 4 of the fryer (i.e., one end of the bottom plate 42 of the frying frame 4), and the second chain 3532 is provided with a second connector 382 for connecting to the other end of the frying frame 4 of the fryer (i.e., the other end of the bottom plate 42 of the frying frame 4). It should be understood that the first connector 381 and the second connector 382 provide double-sided support for the frying frame 4, so that the first chain 3531 and the second chain 3532 drive the frying frame 4 to move smoothly and complete the frying process.

[0080] Specifically, the first connector 381 includes a first connecting block 3811 and a second connecting block 3812 perpendicularly connected to the first connecting block 3811. The second connector 382 includes a third connecting block 3821 and a fourth connecting block 3822 perpendicularly connected to the third connecting block 3821. The first connecting block 3811 is disposed on the inner side of the first chain 3531 facing the second chain 3532. The second connecting block 3812 is disposed on the bottom wall of one end of the bottom plate 42. The third connecting block 3821 is disposed on the inner side of the second chain 3532 facing the first chain 3531. The fourth connecting block 3822 is disposed on the bottom wall of the other end of the bottom plate 42.

[0081] It should be understood that the first connector 381 and the second connector 382 transmit the horizontal tension of the chain 353 to the bottom plate 42. The first connecting block 3811 and the third connecting block 3821 are located inside the chain 353, which can reduce the overall width and avoid interference with the surrounding structure. At the same time, the second connecting block 3812 and the fourth connecting block 3822 have a large contact area with the bottom wall of the bottom plate 42, which effectively prevents the frying frame 4 from loosening or falling off during vigorous frying and boiling.

[0082] In this embodiment, the other end of the upper cover 2 is provided with a support structure 6 for supporting the other end of the upper cover 2 at a preset height. It should be understood that the support structure 6 can support the other end of the upper cover 2 at a preset height, so that the receiving cavity 11 can be exposed to the outside, which is convenient for cleaning and maintenance.

[0083] Specifically, the support structure 6 includes a first extension plate 61, a second extension plate 62, a connecting rod 63, and a support rod 64.

[0084] The first extension plate 61 is disposed on one side of the other end of the upper cover 2, and the second extension plate 62 is disposed on the other side of the other end of the upper cover 2. The two ends of the connecting rod 63 are disposed between the end of the first extension plate 61 away from the upper cover 2 and the end of the second extension plate 62 away from the upper cover 2. The support rod 64 is rotatably disposed inside the connecting rod 63 and is used to support the other end of the receiving cavity 11 of the fryer body 1. That is, when the upper cover 2 is flipped up and opened, the support rod 64 can rotate relative to the connecting rod 63 and swing downward, so that its end abuts against the upper surface of the other end of the receiving cavity 11 of the fryer body 1, suspending the upper cover 2 at a preset height, preventing the upper cover 2 from automatically closing or shaking due to gravity or accidental contact, and ensuring the safety and stability of the cleaning process.

[0085] It is worth noting that the support rod 64 is inserted inside the connecting rod 63, and the outer diameter of the support rod 64 is equal to the inner diameter of the connecting rod 63, which causes a certain amount of friction between the support rod 64 and the connecting rod 63.

[0086] Preferably, a first locking block 711 and a second locking block 712 are spaced apart on the top surface of the other end of the receiving cavity 11 of the fryer body 1. The support rod 64 includes a first support rod 641, a second support rod 642 and a third support rod 643. The first support rod 641 passes through and is rotatably disposed in one end of the first extension plate 61, the connecting rod 63 and one end of the second extension plate 62. One end of the second support rod 642 is connected to one end of the first support rod 641 and the other end of the second support rod 642 is used to lock in the first locking block 711. One end of the third support rod 643 is connected to the other end of the first support rod 641 and the other end of the third support rod 643 is used to lock in the second locking block 712.

[0087] It should be understood that by setting a first locking block 711 and a second locking block 712 at intervals on the top surface of the fryer body 1, and cooperating with a support rod 64 of a specific shape composed of a first support rod 641, a second support rod 642, and a third support rod 643, the second support rod 642 and the third support rod 643 are respectively locked into the corresponding first locking block 711 and the second locking block 712, which further enhances the lateral stability and positioning accuracy of the upper cover 2 in the open state and prevents the upper cover 2 from sliding left or right or tipping over during cleaning operations.

[0088] Preferably, the first support rod 641 is perpendicularly connected to the second support rod 642 and the third support rod 643 respectively, the second support rod 642 and the third support rod 643 are of equal length, the first locking block 711 is arc-shaped and is arranged towards the cover body 23, and the second locking block 712 is arc-shaped and is arranged towards the cover body 23.

[0089] It should be understood that the arc-shaped locking block serves as a guide and limiter, allowing the ends of the second support rod 642 and the third support rod 643 to smoothly and tightly embed into the slot. This ensures the stability of the support and enables rapid self-locking and unlocking of the support state, so that the operator does not need to exert effort to align when opening and closing the upper cover 2.

[0090] Furthermore, a first protruding plate 721 and a second protruding plate 722 are respectively spaced apart on both sides of one end of the receiving cavity 11 of the fryer body 1, and a third extension plate 731 and a fourth extension plate 732 are respectively spaced apart on both sides of one end of the upper cover 2, wherein the third extension plate 731 and the first protruding plate 721 are rotatably connected, and the fourth extension plate 732 and the second protruding plate 722 are rotatably connected.

[0091] Specifically, the top end of the first protrusion 721 is provided with a first receiving slot 7211, the third extension plate 731 is provided with a first rotating shaft 7311 that is received and rotatably disposed within the first receiving slot 7211, the top end of the second protrusion 722 is provided with a second receiving slot 7221, and the fourth extension plate 732 is provided with a second rotating shaft 7321 that is received and rotatably disposed within the second receiving slot 7221.

[0092] Preferably, the receiving cavity 11 of the fryer body 1 is provided with a first baffle 241 and a second baffle 242 at intervals along its length on both sides, wherein the upper cover 2 is located between the first baffle 241 and the second baffle 242.

[0093] It should be understood that the first baffle 241 and the second baffle 242 form a lateral shielding structure. This structure can block some of the laterally splashed oil droplets when the fryer is working, reducing the direct adhesion of oil stains to the edge of the upper cover 2 and the top surface of the fryer body 1, thereby reducing the frequency and difficulty of cleaning and improving the protective performance of the equipment.

[0094] It is worth noting that when the other end of the upper cover 2 is supported at a preset height by the support structure 6, both the second support rod 642 and the third support rod 643 are inclined. That is, when the other end of the upper cover 2 is supported at a preset height by the support structure 6, the distance between the projection position of the connecting rod 63 on the top surface of the fryer body 1 and the first protruding plate 721 is less than the distance between the first locking block 711 and the first protruding plate 721.

[0095] Preferably, the upper cover 2 is in the shape of an isosceles trapezoid, wherein the outer cover 23 is provided with a handle 231.

[0096] It should be understood that the upper cover 2 adopts an isosceles trapezoidal shape design, which matches the opening shape of the receiving cavity 11 of the fryer body 1, making it easy to achieve positioning and sealing when the cover is closed. The handle 231 provided on the cover 23 provides a convenient force point for the operator to open and close the cover 23, making it more convenient to handle food or observe the frying status.

[0097] Preferably, the inlet 22 is located between the side and top surfaces of the upper cover 2, wherein one end of the sub-cover 23 is rotatably located on the top surface of the upper cover 2.

[0098] Furthermore, such as Figure 21 As shown, the present invention also discloses a processing method for a poultry fryer, the processing method comprising the following steps: Step S101: When poultry needs to be fried, the cover 23 is opened to expose the inlet 22, and the electric heater 111 is controlled by the controller 12 to heat the oil in the receiving cavity 11, and the temperature sensor 112 is used to detect the temperature value of the hot oil in the receiving cavity 11 in real time.

[0099] It should be understood that opening the cover 23 exposes the inlet 22, providing an operational channel for the feeding of poultry to be fried. During non-feeding periods, keeping the cover 23 closed can reduce hot oil splashing and heat loss. The controller 12 controls the electric heater 111 to start heating, gradually raising the oil temperature in the containment cavity 11 to the required frying temperature. The temperature sensor 112 collects oil temperature data in real time and feeds it back to the controller 12, forming a closed-loop temperature monitoring system, providing a basis for subsequent precise temperature control.

[0100] Step S102: When the temperature of the hot oil in the containment cavity 11 reaches the preset temperature value, the controller 12 controls the drive motor 14 to work, so that the drive motor 14 drives the frying frame 4 on the transmission chain mechanism 3 to rotate evenly in the preset direction at the preset speed.

[0101] Preferably, the rotation speed of the frying frame 4 is such that the time the frying frame 4 is immersed in the hot oil in the receiving cavity 11 is within the standard frying time period, and the preset direction is the order of the inlet 22, the receiving cavity 11 and the outlet 24.

[0102] It should be understood that the drive motor 14 is only activated after the oil temperature reaches the preset value, ensuring that the poultry is at the standard frying temperature from the moment it enters the oil, thus avoiding excessive oil absorption or incomplete frying due to insufficient oil temperature. The rotation speed of the frying frame 4 is matched with the oil immersion time, ensuring that the residence time of each portion of material in the hot oil is constant within the standard frying time period, guaranteeing the consistency of product cooking degree and color between batches. The preset direction circulates in the order of inlet 22, receiving cavity 11, and outlet 24, so that the three processes of loading, frying, and unloading are naturally connected in space, realizing continuous assembly line operation.

[0103] Step S103: Place the poultry to be fried into the fryer for frying.

[0104] Preferably, such as Figure 22 As shown, step S103, which involves placing the poultry to be fried into the fryer for frying, includes: Step S1031: The poultry to be fried is manually placed into the frying frame 4 corresponding to the inlet 22 through the inlet 22.

[0105] It should be understood that the operator places the poultry to be fried one by one into the frying frame 4 that has been moved to the position at the inlet 22. The continuous operation of the chain 353 makes each frying frame 4 pass through the inlet 22 in sequence, so as to achieve fixed-point and fixed-quantity loading.

[0106] Step S1032: The transmission chain mechanism 3 drives the poultry in the frying frame 4 into the hot oil in the receiving cavity 11 for frying.

[0107] It should be understood that after the frying frame 4 is loaded with materials, it is gradually immersed in the hot oil in the receiving cavity 11 as the chain 353 moves. The materials are in full contact with the high-temperature oil in the closed frying space, completing the heat transfer and cooking process. The uniform movement of the chain 353 ensures that the frying time of each batch of materials is consistent, achieving standardized frying.

[0108] Step S1033: When the transmission chain mechanism 3 drives the fried poultry in the frying frame 4 to rotate to the outlet 24 and the position of the frying frame 4 is higher than the position of the receiving shelf 13 by a preset height, the fried poultry in the frying frame 4 will cause the movable plate 41 to rotate according to its own gravity, so that the fried poultry in the frying frame 4 will automatically fall from the frying frame 4 into the receiving shelf 13.

[0109] It should be understood that when the frying frame 4 moves above the discharge port 24 and reaches the preset height difference, the movable plate 41 automatically flips and opens under the action of the material's own gravity. The fried material slides down to the receiving rack 13 without manual intervention, realizing automatic unloading.

[0110] Furthermore, such as Figure 23As shown, the processing method of the poultry fryer disclosed in this invention further includes the following steps: Step S201: When the temperature value of the hot oil in the receiving cavity 11 is lower than the warning temperature value detected by the temperature sensor 112, the controller 12 controls the electric heater 111 to work to heat the hot oil in the receiving groove 113.

[0111] It should be understood that when the temperature sensor 112 detects that the oil temperature has dropped below the warning temperature value, it indicates that the current oil temperature is insufficient to maintain the normal frying effect. The controller 12 automatically starts the electric heater 111 to reheat the hot oil in the receiving groove 113, so that the oil temperature can be restored to the set range in time, ensuring that the subsequent materials can still be under the standard frying temperature conditions.

[0112] Step S202: The controller 12 controls the operation of the circulation pump 54 to pump the hot oil in the receiving groove 113 to the filter 52 for filtration, and after filtration, it is pumped back into the receiving groove 113 through the third circulation pipe 55. The hot oil entering the receiving groove 113 is pre-filtered by the filter screen 114.

[0113] It should be understood that the controller 12 controls the operation of the circulation pump 54 to extract the hot oil from the receiving groove 113 and transport it to the filter 52 for filtration and purification, removing fine impurities and carbonized particles from the oil. The filtered clean oil then flows back to the receiving groove 113 through the third circulation pipe 55 for continued use. The filter screen 114 at the inlet of the receiving groove 113 pre-intercepts larger impurities, reducing the processing load on the filter 52 and extending its maintenance cycle. Through continuous online circulation filtration, the deterioration rate of the frying oil is effectively slowed down, extending the service life of the oil and reducing oil change costs.

[0114] Furthermore, the processing method of the poultry fryer disclosed in this invention also includes the following steps: Step S301: When maintenance or cleaning is required, manually lift the other end of the upper cover 2, rotate the support rod 64 and make the other end of the second support rod 642 locked in the first locking block 711 and the other end of the third support rod 643 locked in the second locking block 712, so that the other end of the upper cover 2 is supported at a preset height.

[0115] It should be understood that after lifting the other end of the upper cover 2, the support rod 64 is rotated to engage with the corresponding locking block. The mechanical cooperation between the support rod 64 and the locking block securely supports the upper cover 2 at a preset height, fully exposing the receiving cavity 11 and its internal components. This supported configuration effectively prevents the upper cover 2 from accidentally falling during maintenance or cleaning, ensuring the safety of operators, while also providing ample operating space for maintenance operations such as cleaning oil stains and replacing parts.

[0116] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0117] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
