Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to an oil-saving device for frying systems. Background Technology

[0002] This deep fryer employs an advanced oil-water mixing frying process, completely transforming the structure of traditional frying equipment and fundamentally solving the drawbacks of traditional deep fryers. It can fry various foods simultaneously without cross-contamination of flavors, making it a multi-functional machine. This process uses heating from the middle of the oil layer, controlling the temperature of the upper and lower oil layers, effectively mitigating oil oxidation and inhibiting the rise of acidic media. It automatically filters residue and controls temperature during the frying process, extending the machine's lifespan. Existing deep fryers mostly require manual insertion of the oil filter into the oil and manual removal after frying, which is cumbersome and physically demanding for extended periods. Furthermore, the odors produced during frying can be unpleasant to those nearby.

[0003] A fuel-saving fryer, disclosed in CN213756449U, includes a main body and an oil storage tank nested within its inner cavity. The inner cavity of the oil storage tank also houses an outer frame and an oil filter hood welded to the bottom wall of the outer frame. Support rods are welded to both sides of the outer wall of the main body. Storage tanks and positioning frames are located on the outside of and adhered to the storage tanks on both sides of the bottom wall of the main body. Two sets of frames, each adhered to the top wall of one set of support rods, and absorption nozzles, each adhered to the side walls of one set of frames, are located above the main body. The inner cavities of the two sets of support rods are located on opposite sides. This fuel-saving fryer, by incorporating stepper motors, lead screws, lifting blocks, and an outer frame, allows the two sets of stepper motors to work simultaneously, driving the outer frame to move up and down, thus automatically moving the oil filter hood up and down. This makes the feeding and removal of food more convenient and saves manpower.

[0004] The above technical solution has some problems in practical application. The technical solution treats the oil inside the fryer, which not only affects the frying operation, but also makes it inconvenient to clean the filter residue.

[0005] Therefore, it is necessary to invent an oil-saving device for frying systems to solve the above problems. Utility Model Content

[0012] Preferably, a baffle is fixedly installed inside the partition, and the baffle is in contact with the bottom end of the first filter screen. A through groove corresponding to the movable cylinder is opened in the middle of the baffle.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model features a processing tank with an inlet at the bottom and an outlet at the top. A second and a first filter screen are installed inside the tank, allowing oil to pass through and filter out fried and suspended solids, thus achieving oil filtration. The entire filtration mechanism is integrated within the processing tank, which can be connected to multiple frying devices via an inlet and an outlet. This achieves oil filtration without affecting the normal operation of the frying devices.

[0015] 2. This utility model incorporates a movable cylinder inside the second and first filter screens. Multiple suction nozzles are located at the top outer side of the movable cylinder, and a rotating rod is located on the inner side of the cylinder. A spiral guide plate is located on the outer side of the rotating rod. When cleaning the first filter screen, the movable cylinder drives the suction nozzles to rotate, and the rotating rod drives the guide plate to rotate within the movable cylinder. This generates a downward driving force within the movable cylinder, creating negative pressure and effectively cleaning the oil residue from the surfaces of the first and second filter screens, thus facilitating long-term use of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 The oil-saving device for a frying system shown includes a processing tank 1, an oil inlet 3 fixedly provided at the bottom of the outer side wall of the processing tank 1, an oil outlet 2 fixedly provided at the top of the outer side wall of the processing tank 1, a slag discharge port 4 fixedly provided at the bottom of the processing tank 1, and a top cover 5 fixedly provided at the top of the processing tank 1.

[0023] Specifically, a first filter screen 7 is fixedly installed inside the treatment tank 1. A second filter screen 8 is inserted into the top of the first filter screen 7, and the top of the second filter screen 8 is attached to the lower surface of the top cover 5. The first filter screen 7 and the second filter screen 8 have the same pore size, which can filter the upper and lower layers of oil respectively. An oil inlet pipe 6 is fixedly installed at the top of the outer wall of the second filter screen 8, and one end of the oil inlet pipe 6 corresponds to the oil inlet 3. Multiple pleats 9 are arranged around the inner side wall of the second filter screen 8. The oil sludge will float on the upper layer of oil under the action of buoyancy and be filtered by the second filter screen 8. The filtered oil sludge can be limited by the pleats 9 to prevent the oil sludge from continuing to float.

[0024] More specifically, the second filter screen 8 has a movable cylinder 10 inside, and multiple extension covers 11 are fixedly installed on the outside of the movable cylinder 10. A suction nozzle 12 is fixedly installed on the outer wall of the extension cover 11, and a scraper is fixedly installed at one end of the suction nozzle 12. The scraper can scrape off and clean the oil residue attached to the inner wall of the second filter screen 8 and the first filter screen 7.

[0025] Furthermore, the movable cylinder 10 is equipped with a rotating rod 13 inside, and a spiral guide plate 14 is arranged around the outside of the rotating rod 13. A sliding sealing gasket is provided between the guide plate 14 and the inner wall of the movable cylinder 10. The sliding sealing gasket ensures the oil extraction and conveying effect of the guide plate 14 and the movable cylinder 10. In addition, a solenoid valve is provided at the bottom of the movable cylinder 10. The solenoid valve can prevent oil from being discharged through the movable cylinder 10 when the device is not performing self-cleaning.

[0026] Furthermore, a transmission sleeve 15 is fixedly installed at the top of the movable cylinder 10, and the transmission sleeve 15 is rotatably installed in the middle of the top cover 5. A motor 16 is fixedly installed on the upper surface of the top cover 5. A bevel gear set 17 is provided between the output shaft of the motor 16, the transmission sleeve 15 and the rotating rod 13. The motor 16 can drive the movable cylinder 10 and the rotating rod 13.

[0027] Meanwhile, a partition 18 is fixedly installed at the bottom of the interior of the treatment tank 1, and the partition 18 corresponds to the bottom of the first filter screen 7. A baffle 19 is fixedly installed inside the partition 18, and the baffle 19 fits against the bottom of the first filter screen 7. A through groove corresponding to the movable cylinder 10 is opened in the middle of the baffle 19. The partition 18 can divide the internal space of the treatment tank 1 to ensure that the filtered pure oil is located at the top and discharged through the oil outlet 2. The baffle 19 can seal the bottom of the first filter screen 7 to prevent the oil from being discharged directly through the slag discharge port 4.

[0028] Working principle of this utility model:

[0029] When this device is in use, the processing tank 1 is connected to the frying equipment through the oil inlet 3 and the oil outlet 2. The oil used in the frying equipment enters the processing tank 1 through the oil inlet 3. The oil enters the interior of the second filter screen 8 and the first filter screen 7 through the oil inlet 3 and the oil inlet pipe 6, and then passes through the second filter screen 8 and the first filter screen 7 to reach the top of the partition 18, and then is discharged through the oil outlet 3. During this process, the oil residue and suspended matter in the oil are filtered by the first filter screen 7 and the second filter screen 8 to achieve the filtration and recovery of the oil. In addition, the oil residue in the oil is located at the top under the action of buoyancy, is filtered by the second filter screen 8, and is restricted by the folds 9 to stop floating.

[0030] When cleaning the interior of the second filter screen 7 and the first filter screen 8, the motor 16 drives the transmission sleeve 15 and the rotating rod 13 to rotate through the bevel gear set 17. The transmission sleeve 15 drives the movable cylinder 10 to rotate, and the movable cylinder 10 drives the suction nozzle 12 to rotate, so that the suction nozzle 12 moves along the inner wall of the first filter screen 8. At the same time, the rotating rod 13 drives the guide plate 14 to rotate. The guide plate 14 applies a downward force to the movable cylinder 10 through its spiral structure, so that a negative pressure is generated inside the movable cylinder 10. During this process, the movable cylinder 10 drives the extension cover 11 and the suction nozzle 12 to rotate. The suction nozzle 12 scrapes off the oil residue from the inner wall of the first filter screen 7 and the second filter screen 8 through the scraper on its outer side. The oil residue is extracted and transported to the bottom of the partition plate 18 under the action of negative pressure, and then discharged through the slag discharge port 4.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
