Description

Technical Field

[0001] This invention relates to the field of food processing equipment technology, specifically to a food frying equipment. Background Technology

[0002] Potato chips are a popular snack, typically made by frying or baking slices of sweet potatoes or potatoes. Frying is the more efficient and flavorful method, making it the mainstream method for producing potato chips. However, the frying process generates a lot of crumbs and residue. Repeated frying of these crumbs and residues can degrade the quality of the frying oil, worsen the flavor of freshly fried chips, and may even produce substances harmful to health.

[0003] Therefore, when frying potato chips, a slag removal mechanism is installed on the frying equipment. For example, Chinese Patent Application No. 2024229598474 discloses a continuous fryer that uses a drive chain assembly to drive multiple waste push rods and, together with auxiliary scrapers, scrapes and cleans the waste residue on the inner wall of the oil tank. However, in actual use, the scraping structure is mainly aimed at large particles of waste residue deposited at the bottom of the oil tank. For debris suspended in the oil and floating on the oil surface, the scraping structure has difficulty reaching them and cannot achieve effective separation, resulting in the continuous accumulation of debris in the oil and affecting the frying quality. Summary of the Invention

[0004] In view of the shortcomings of the existing technology and to overcome its defects, the present invention aims to provide a food frying device that solves the technical problem that existing continuous frying devices cannot completely remove debris from the oil.

[0005] The technical solution is a food frying device, including a support frame, a frying chamber mounted on the support frame, a partition plate mounted inside the frying chamber, the partition plate dividing the internal space of the frying chamber into a frying cavity for frying materials and a flow cavity for liquid flow, and through holes at both ends of the partition plate, the frying cavity and the flow cavity forming an annular flow channel through the through holes.

[0006] The frying chamber is equipped with a pushing component and a separating component. The pushing component is used to push the material in the frying chamber to move along the annular flow channel in the forward or reverse direction to the through hole. Each of the separating components is used to separate the solid material passing through the through hole and remove it from the frying chamber.

[0007] A conveying mechanism is installed on the support frame. The conveying mechanism is used to move the material outside the frying box after passing through the frying chamber to the outside of the frying box. The distance between the conveying mechanism and the frying box is adjustable.

[0008] Preferably, each of the separation components includes a filter screen, each filter screen isolates the frying chamber and the flow chamber at the through hole, the lower part of each filter screen is located in the annular flow channel, the upper part of each filter screen is located above the annular flow channel, and is rotatably connected to the frying box body.

[0009] Preferably, the bottom of the support is fixedly connected to the fixed end of the telescopic component, the moving end of the telescopic component is fixedly connected to the frying box, the support and the conveying mechanism are fixed in relative position, and an adjustable guide rod is installed between the bottom of the support and the frying box. The axial directions of each guide rod and the telescopic component are parallel and located in the vertical direction.

[0010] Preferably, a vibration assembly is installed on the frying box, and each vibration assembly is used to drive the filter screen to vibrate by rotating the filter screen when the material on the filter screen leaves the filter screen outside the frying box.

[0011] Preferably, each of the vibration components includes a connecting rod, which is fixedly connected to a filter screen and rotatably connected to a frying box. One end of the connecting rod is fixedly connected to a spring rod made of elastic material. A fixing strip is installed on the frying box, and several blocks are installed on the fixing strip. Each block is distributed in an arc around the connecting rod, and each block collides and contacts the end of the spring rod away from the connecting rod.

[0012] Preferably, the pushing component includes a push plate, which is slidably connected to the frying box, and the side of the push plate that contacts the filter screen is an arc-shaped curved surface structure formed by the rotation of the outer edge of the filter screen.

[0013] Preferably, the push plate is threaded with lead screws on both sides, and each lead screw is rotatably connected to the frying box.

[0014] Preferably, a cover is provided above the support, and an air inlet is opened at the upper end of the cover. Each air inlet is connected to a flue gas duct. A liquid storage tank is provided on the cover, and a liquid chamber is provided inside the liquid storage tank. The air outlet of the flue gas duct is located in the liquid chamber, and an assist component for pushing the airflow outward through the liquid chamber is provided at the flue gas duct.

[0015] Preferably, the flue gas duct includes a horizontal pipe, which is connected to each air inlet, air outlet, and conduit. The air outlet and conduit have the same inner diameter and are coaxially arranged. The air outlet is located below the horizontal pipe, and its lower end is the air outlet. The conduit is located above the horizontal pipe. The assisting component includes a plug, which is slidably disposed inside the conduit and reciprocates along the conduit axis. The upper end of the plug is always located inside the conduit, and the lower end of the plug is alternately located inside or above the air outlet. Sealing rings are installed at both ends of the plug.

[0016] This invention provides a food frying device, which has the following advantages compared with the prior art:

[0017] 1. By setting up a partition plate inside the frying box to form an annular flow channel, the oil is propelled to flow in the annular flow channel by the pushing component, so that various debris in the oil flows with the oil to the through hole and is intercepted and carried out by the separation component, thereby achieving complete separation of debris in the oil and preventing debris from being repeatedly fried, which would affect the quality of the frying oil and the flavor of the product.

[0018] 2. By setting up a vibration component, vibration is generated when the filter screen rotates outside the frying box, which causes the debris attached to the surface of the filter screen to quickly detach and fall into the collection box, preventing the filter screen from clogging after long-term use.

[0019] 3. The arc-shaped curved surface design of the push plate and the outer edge of the filter screen ensures that when the filter screen rotates away from the frying box, all solid materials between the filter screen and the push plate are intercepted and separated by the filter screen and removed from the frying box, thus achieving complete separation of debris in the oil.

[0020] 4. By reciprocating the plunger inside the conduit, the fumes above the frying box are actively drawn in and pressed into the liquid chamber, improving the efficiency of fume collection and treatment and preventing fumes from escaping. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0034] Please see Figure 1-7This invention provides a technical solution: a food frying device, including a support 1, on which a frying chamber 2 is mounted. The frying chamber 2 is a rectangular box structure with an open top, and is filled with frying oil. A partition plate 3 is installed inside the frying chamber 2, which divides the internal space of the frying chamber 2 into a frying cavity 2.1 for frying materials such as potato chips and a circulation cavity 2.2 for the flow of liquids such as oil. Two through holes 4 are opened at both ends of the partition plate 3. The frying cavity 2.1 and the circulation cavity 2.2 are connected by the through holes 4 to form an annular flow channel, and the oil can circulate between the frying cavity 2.1 and the circulation cavity 2.2.

[0035] The frying chamber 2 is equipped with a pushing component 5 and a separating component 6. The pushing component 5 is used to push the material in the frying chamber 2.1 to move along the annular flow channel in the forward or reverse direction to the through hole 4. Each of the separating components 6 is used to separate and remove solid materials such as debris and residue that pass through the through hole 4 from the frying chamber 2. There are two separating components 6, one at each through hole 4.

[0036] The support 1 is equipped with a conveyor mechanism 7, which is a conveyor belt structure used in existing frying equipment. The conveyor mechanism 7 is used to move the material outside the frying box 2 after passing through the frying chamber 2.1 to the outside of the frying box 2. The distance between the conveyor mechanism 7 and the frying box 2 is adjustable.

[0037] In use, the potato chip ingredients to be fried are fed into the frying chamber 2.1 of the frying box 2 via the conveying mechanism 7, and fried in high-temperature oil. At this time, the pusher plate 5.1 in the pushing assembly 5 is located at one end of the frying box 2, which can be located at the left end of the frying box 2. Figure 1As shown, at appropriate time intervals, such as five minutes, ten minutes, or fifteen minutes, the height of the frying chamber 2 is lowered or the height of the conveying mechanism 7 is raised, so that the conveying mechanism 7 is above the frying chamber 2.1. Then, the pushing component 5 pushes the oil and debris generated during frying, as well as other materials in the frying chamber 2.1, to move them forward along the annular flow channel, that is, to move the materials in the frying chamber 2.1 from left to right. This causes the oil to flow into the circulation chamber 2.2 through the through hole 4 on the right side. The debris is intercepted by the separation component 6 at the through hole 4 on the right side and removed from the frying chamber 2. At the same time, the clean oil flowing into the circulation chamber 2.2 flows back into the frying chamber 2.1 through the through hole 4 on the left side. Then, the height of the frying box 2 is raised or the height of the conveying mechanism 7 is lowered, so that the lower part of the conveying mechanism 7 is located inside the frying chamber 2.1, thereby frying the potato chip raw materials. After an appropriate time interval, the height of the frying box 2 is lowered or the height of the conveying mechanism 7 is raised, so that the conveying mechanism 7 is located above the frying chamber 2.1. Then, the pushing component 5 pushes the oil and the debris and residue generated during the frying process to move in the opposite direction along the annular flow channel, that is, the material in the frying chamber 2.1 moves from right to left, so that the oil flows into the flow chamber 2.2 through the through hole 4 on the left side, and the debris and residue are intercepted by the separation component 6 at the through hole 4 on the left side and removed from the frying box 2. Figure 1-3 As shown, the clean oil flowing into the circulation chamber 2.2 flows back to the frying chamber 2.1 through the through hole 4 on the right side, and circulates in sequence to achieve complete separation of debris in the oil, preventing debris from being repeatedly fried and thus affecting the quality of the frying oil and the flavor of the product.

[0038] In order to separate and remove the solid material passing through the through hole 4 from the frying box 2, such as Figure 2 , Figure 4 As shown, each of the separation components 6 includes a filter screen 6.1. The mesh size of the filter screen 6.1 is determined according to the size of the debris, preferably 80 to 200 mesh. Each filter screen 6.1 separates the frying chamber 2.1 and the flow chamber 2.2 at the through hole 4. The lower part of each filter screen 6.1 is located inside the annular flow channel, and the upper part of each filter screen 6.1 is located above the annular flow channel and is rotatably connected to the frying box 2. When the oil flows in the annular flow channel, the debris reaches the through hole 4 with the oil, is intercepted by the filter screen 6.1, and adheres to the surface of the filter screen 6.1. The filter screen 6.1 rotates around the pivot, carrying the debris attached to the surface out of the oil to the outside of the frying box 2, thereby achieving the separation of debris from oil.

[0039] To prevent filter 6.1 from clogging after prolonged use, such as Figure 4-5 As shown, a vibration assembly 8 is installed on the frying box 2. Each vibration assembly 8 is used to drive the filter screen 6.1 to vibrate when the material on the filter screen 6.1 leaves the filter screen 6.1 outside the frying box 2.

[0040] Specifically, each of the vibration components 8 includes a connecting rod 8.1, which is welded and fixed to the filter screen 6.1. The connecting rod 8.1 is rotatably connected to the frying box 2. One end of the connecting rod 8.1 is fixedly connected to a spring rod 8.2 made of elastic material, such as spring steel. The spring rod 8.2 is snapped and fixed to the connecting rod 8.1, or it can be welded. A fixing strip 8.3 is welded onto the frying box 2. Several blocks 8.4 are installed on the fixing strip 8.3. The fixing strip 8.3 and the blocks 8.4 are an integral structure. Each block 8.4 is distributed in an arc shape around the connecting rod 8.1. Each block 8.4 collides and contacts the end of the spring rod 8.2 away from the connecting rod 8.1.

[0041] When the filter screen 6.1 rotates, the connecting rod 8.1 drives the spring rod 8.2 to rotate synchronously. The end of the spring rod 8.2 away from the connecting rod 8.1 collides with each stop block 8.4 in sequence, thereby generating vibration. This vibration is transmitted to the filter screen 6.1 through the connecting rod 8.1, causing the filter screen 6.1 to vibrate. Debris adhering to the surface of the filter screen 6.1 is quickly detached under the action of vibration. Figure 4 As shown, when the lower part of the filter screen 6.1 rotates from inside the frying chamber 2.1 to the other side of the connecting rod 8.1, the material on the filter screen 6.1 moves downward and detaches from the filter screen 6.1 under the influence of its own gravity. The filter screen 6.1 continues to rotate, and the elastic rod 8.2 begins to collide with each stop block 8.4, causing the filter screen 6.1 to vibrate.

[0042] The frying box 2 is equipped with a collection box 9, such as... Figure 2 As shown, the collection box 9 and the frying box 2 are an integral structure, or they can be welded together. There are two collection boxes 9, located on both sides of the frying box 2. Each collection box 9 is located on the side of the connecting rod 8.1 opposite to the filter screen 6.1, that is, below the filter screen 6.1 when it rotates to the outside of the frying box 2. Debris detached from the filter screen 6.1 falls into the collection box 9 for easy collection and cleaning. The end of the connecting rod 8.1 away from the elastic rod 8.2 is fixedly connected to the output shaft of the servo motor. The servo motor is bolted to the frying box 2. The rotation of the servo motor drives the filter screen 6.1 to rotate.

[0043] In order to ensure that all solid material at the through-hole 4 is intercepted, separated, and removed from the frying box 2 by the filter screen 6.1, such as... Figure 1-2As shown, the pushing component 5 includes a push plate 5.1, which is slidably connected to the frying tank 2. The side of the push plate 5.1 that contacts the filter screen 6.1 is an arc-shaped curved surface structure formed by the rotation of the outer edge of the filter screen 6.1. When the push plate 5.1 pushes the material to the through hole 4, the arc-shaped curved surface cooperates with the outer edge of the filter screen 6.1, so that when the filter screen 6.1 rotates, the outer edge of the filter screen 6.1 contacts the arc-shaped curved surface. Therefore, when the filter screen 6.1 rotates away from the frying tank 2, all the solid material between the filter screen 6.1 and the push plate 5.1 is intercepted, separated, and removed from the frying tank 2 by the filter screen 6.1, thus achieving complete separation of debris in the oil.

[0044] In order to move the push plate 5.1, such as Figure 6 As shown, the push plate 5.1 is threadedly connected to lead screws 5.2 on both sides. Each lead screw 5.2 is rotatably connected to the frying box 2 via bearings, and one end of the lead screw 5.2 is connected to a drive motor. The drive motor drives the lead screw 5.2 to rotate, and the lead screw 5.2 drives the push plate 5.1 to slide back and forth along the length of the frying box 2, thereby realizing the function of pushing materials. By controlling the rotation direction of the lead screw 5.2, the push plate 5.1 can be controlled to move forward or backward along the annular flow channel.

[0045] Among them, a fixed limiting block 12 can be welded onto the frying box 2, such as Figure 4 As shown, each limiting block 12 is located at both ends of the lead screw 5.2. When the push plate 5.1 contacts the left limiting block 12, the left curved surface of the push plate 5.1 engages with the outer edge of the left filter screen 6.1. When the push plate 5.1 contacts the right limiting block 12, the right curved surface of the push plate 5.1 engages with the outer edge of the right filter screen 6.1. The limiting blocks 12 restrict the movement of the push plate 5.1. A limiting strip 13 can be welded to the bottom of the frying box 2. When the filter screen 6.1 contacts the limiting strip 13, the side of the filter screen 6.1 engages with the inner surface of the through hole 4, as shown in the figure. This isolates the frying chamber 2.1 and the flow chamber 2.2 at the through hole 4.

[0046] To adjust the distance between the conveyor mechanism 7 and the frying box 2, such as Figure 1-3As shown, the bottom of the support 1 is bolted to the fixed end of the telescopic member 10, and the moving end of the telescopic member 10 is bolted to the frying box 2. The telescopic member 10 is preferably a cylinder or a hydraulic cylinder. The support 1 and the conveying mechanism 7 are fixed in relative position. The mounting bracket in the conveying mechanism 7 can be bolted to the support 1. An adjustable guide rod 11 is installed between the bottom of the support 1 and the frying box 2. The guide rods 11 and the telescopic member 10 are axially parallel and located in the vertical direction. Each guide rod 11 consists of two rods that slide together. One rod is welded to the support 1, and the other rod is welded to the frying box 2. There are four guide rods 11, distributed along the circumference of the frying box 2, used to guide the lifting and lowering movement of the frying box 2 and ensure stability during the lifting and lowering process. The height of the frying box 2 relative to the support 1 can be adjusted by the telescopic member 10, thereby adjusting the vertical distance between the conveying mechanism 7 and the frying box 2.

[0047] Example 2

[0048] Based on Example 1, such as Figure 8-9 As shown, to purify the fumes, a cover 16 is installed above the support 1. The cover 16 is welded or bolted to the support. An air inlet 17 is opened at the upper end of the cover 16, and each air inlet 17 is connected to the flue gas duct 18. The fumes enter the flue gas duct 18 through the air inlet 17. A liquid storage tank 19 is bolted to the cover 16. A liquid chamber 20 is set inside the liquid storage tank 19. The liquid chamber 20 contains a liquid, such as water or an alkaline solution, for absorbing harmful substances in the fumes. The air outlet 18.4 of the flue gas duct 18 is located inside the liquid chamber 20. The fumes enter the liquid in the liquid chamber 20 through the air outlet 18.4 and are washed and purified by the liquid. The purified gas is discharged directly from the liquid storage tank 19. An assist component is installed at the flue gas duct 18 to push the airflow out of the liquid chamber 20. The assist component is used to draw the fumes into the flue gas duct 18 and press them into the liquid chamber 20, facilitating the treatment of the fumes.

[0049] To allow oil fumes to enter the flue gas duct 18 and be forced into the liquid chamber 20 through the air inlet 17, the flue gas duct 18 includes a horizontal pipe 18.1. The horizontal pipe 18.1 is connected to each air inlet 17, an air outlet 18.2, and a conduit 18.3. The air outlet 18.2 and the conduit 18.3 have the same inner diameter and are coaxially arranged. The air outlet 18.2 is located below the horizontal pipe 18.1, and its lower end is the air outlet 18.4. The conduit 18.3 is located above the horizontal pipe 18.1. The assisting component includes a plunger 21, which is slidably disposed within the conduit 18.3 and reciprocates along the axial direction of the conduit 18.3. The upper end of plug 1 is always located inside the conduit 18.3, and the lower end of plug 21 is alternately located inside or above the exhaust pipe 18.2. Sealing rings 22 are installed at both ends of plug 21. The sealing ring 22 at the upper end of plug 21 ensures a seal between plug 21 and the inner wall of conduit 18.3, and the sealing ring 22 at the lower end of plug 21 ensures a seal between plug 21 and the inner wall of exhaust pipe 18.2. When plug 21 moves upward, the fumes inside cover 16 are drawn into the flue gas duct 18; when plug 21 moves downward, the fumes are forced into exhaust pipe 18.2 and discharged from exhaust port 18.4 into liquid chamber 20. Through the reciprocating motion of plug 21, continuous intake and exhaust of fumes are achieved.

[0050] The plunger 21 can be driven by a hydraulic cylinder or a pneumatic cylinder to achieve reciprocating motion. Specifically, a hydraulic cylinder or a pneumatic cylinder is installed above the guide tube 18.3, and the piston rod of the hydraulic cylinder or pneumatic cylinder is bolted to the upper end of the plunger 21. The reciprocating motion of the piston rod is controlled by a directional valve of the hydraulic system or pneumatic system, thereby driving the plunger 21 to reciprocate along the axial direction of the guide tube 18.3. The plunger 21 can also be driven by a crank-connecting rod mechanism. Specifically, a motor is bolted to the cover 16, and the output shaft of the motor is connected to a crank. The crank is hinged to the upper end of a vertical rod through a connecting rod, and the lower end of the vertical rod is welded to the plunger 21. The motor drives the crank to rotate continuously, and the rotational motion is converted into the reciprocating linear motion of the plunger 21 through the connecting rod.

[0051] Example 3

[0052] Based on Embodiment 1, the partition plate 3 is snapped and fixed to the frying box 2. The partition plate 3 has a hollow structure inside and an electric heating tube is installed inside the partition plate 3. Other suitable heat sources can also be installed to facilitate heating of the oil in the frying box 2.

[0053] Example 4

[0054] Based on Example 1, such as Figure 2 As shown, an oil outlet pipe 14 is welded to the bottom of the frying box 2, and a valve is installed on the oil outlet pipe 14. The support 1 is bolted to the lower part of the oil outlet pipe 14 to fix the oil storage tank 15. The oil storage tank 15 is slidably connected to the lower end of the oil outlet pipe 14 to prevent it from affecting the up and down movement of the frying box 2.

[0055] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
