Description

Technical Field

[0001] The present invention relates to the technical field of fryers, in particular to a high-efficiency and energy-saving large-scale industrial fryer. Background Art

[0002] Industrial deep fryers are a type of equipment used for large-scale food processing, typically found in fast food restaurants, restaurants, and food processing plants. They typically use oil to heat and fry foods such as French fries, chicken nuggets, and fish fillets. The design of an industrial deep fryer typically includes components such as an oil tank, heating elements, a control panel, and a screen to ensure that the food is evenly fried at high temperatures. This is especially true for dense foods, which absorb oil and increase their weight during frying, causing them to sink in the pan. Proper stirring is necessary to ensure even heating.

[0003] A low-temperature vacuum frying device and processing method (Announcement No.: CN111066834B) in the prior art that is easy to control temperature simplifies the frying oil recovery process through the design of a two-way oil pump, so that the fruit and vegetable slices can be centrifugally de-oiled under a vacuum state immediately after the frying process is completed. The operation is simple, the oil content of the food material product is effectively controlled, and the oil content is lower than that of food fried at room temperature and normal pressure, and the oil consumption is relatively low. However, whether the frying oil in the frying chamber is quickly pumped back to the heating oil tank through the oil pump or the pumped frying oil overflows through the oil overflow port on the side wall and flows into the oil storage tank, the oil residue in the frying oil is not filtered out during the oil return process. Therefore, the oil residue repeatedly enters the frying chamber, which easily damages the appearance of the fried food and produces a burnt smell, thereby reducing the quality of the fried food. Therefore, it is urgent to design a high-efficiency and energy-saving large-scale industrial frying machine that can filter and collect oil residue. Summary of the Invention

[0030] Reference Figures 1-9, a high-efficiency and energy-saving large-scale industrial frying machine, including an equipment box 1, a frying box 2 is fixedly installed on the top of the equipment box 1, and a feeding mechanism is provided on one side of the frying box 2. A main shaft 8 is rotatably installed in the frying box 2, and a transmission sleeve 9 is slidably sleeved on the surface of the main shaft 8. A plurality of storage drawers 27 are fixedly sleeved on the surface of the transmission sleeve 9. A filter box 22 is fixedly installed on one side of the frying box 2. One side of the filter box 22 is connected to the bottom of the frying box 2 through an oil pipe. A filter plate 35 is fixedly installed in the filter box 22, and a scraper 21 with an inverted T-shaped structure is slidably installed on the top of the filter box 22. The bottom of the scraper 21 is against the top of the filter plate 35. Collection boxes 23 are fixedly installed on both opposite sides of the filter box 22. The two collection boxes 23 and the adjacent side of the filter box 22 are provided with a slag discharge port, and a slag collection drawer 36 is slidably installed in each collection box 23. Each collection box 23 is provided with an oil squeezing mechanism, and two first limit slides are symmetrically provided on the surface of the main shaft 8 The transmission sleeve 9 has a hollow structure inside and is provided with two first convex rafters that are adapted to the first limiting slide groove. The bottom of the filter box 22 and the two collecting boxes 23 are both open structures. The second funnel 31 is fixedly installed on the bottom of the filter box 22, and the first funnel 29 is fixedly installed on the bottom of the two collecting boxes 23. A slide groove hole for the sliding of the scraper 21 is opened on the top of the filter box 22, and a first convex shaft is welded on the top of the scraper 21. The oil squeezing mechanism includes an extrusion block 32, a push rod 33 and a plurality of return springs 34. The extrusion block 32 is slidably installed in the collection box 23, and an inclined notch is opened on the side of the extrusion block 32 close to the filter box 22. The filter box 22 and the collection box 23 are adjacent to each other. A slideway adapted to the push rod 33 is opened on the side, and the push rod 33 is slidably installed in the slideway and one end is against the inclined surface opened by the extrusion block 32. Multiple return springs 34 are fixedly installed at one end to the top of the extrusion block 32, and the other end is fixedly installed to the top of the collection box 23.

[0031] During use, by setting the filter box 22 and the two collecting boxes 23, the oil pump 24 is used to extract the frying oil from the frying box 2, the oil residue in the frying oil can be filtered through the filter plate 35 in the filter box 22, and the oil residue on the surface of the filter plate 35 can be scraped off by the reciprocating sliding of the scraper 21 to avoid the oil residue from clogging the filter plate 35, thereby improving the smoothness of the oil circuit of the equipment. The scraper 21 can push the oil residue to both sides of the filter plate 35, and the scraper 21 gradually approaches the inner wall of the filter box 22 until it contacts it, and at the same time pushes the push rod 33 to slide into the collecting box 23, and the squeeze block 32 is squeezed. The notch drives the squeezing block 32 to move upward and compresses the return spring 34. At this time, the scraper 21 pushes the oil residue into the collection box 23 through the slag discharge ports opened on both sides. When the scraper 21 moves away, the squeezing block 32 in the collection box 23 squeezes the oil residue under the action of multiple return springs 34, squeezes out the excess frying oil, and flows it into the circulating oil circuit to avoid waste of frying oil. The oil residue is collected in the slag collection drawer 36 and waits for centralized processing, which effectively prevents the oil residue from participating in the frying operation again and damaging the appearance and taste of the fried food, thereby improving the energy saving effect of the equipment and the quality of the fried food.

[0032] In this embodiment, an oil pump 24 and a heating barrel 20 for heating oil are fixedly installed on one side of the equipment box 1. A four-way pipe 30 is fixedly installed on the oil inlet end of the oil pump 24. The other three ends of the four-way pipe 30 are respectively connected to the bottom of the two first funnels 29 and the second funnel 31. The oil outlet end of the oil pump 24 is connected to the inside of the heating barrel 20 through an oil pipe. An oil inlet connected to an external oil supply device is provided on one side of the heating barrel 20. An oil feed pump 19 is fixedly installed on the top of the heating barrel 20. The oil inlet end of the oil feed pump 19 is connected to the inside of the heating barrel 20. An oil feed pipe 18 with a multi-segment structure is fixedly installed on the oil outlet end of the oil feed pump 19. One end of the oil feed pipe 18 is inserted into the frying box 2 from the top of the frying box 2 and a plurality of oil outlet holes are uniformly opened on the surface in a linear manner.

[0033] During use, a certain amount of oil required is delivered to the heating barrel 20 through an external oil supply device for heating, and then the heated oil is pumped into the frying box 2 through the oil inlet pipe 18 by the oil inlet pump 19. The hot oil can be evenly delivered to the surfaces of the storage drawers 27 on each layer through the multiple oil outlet holes on the surface of the oil inlet pipe 18 until all fried foods are covered by the oil. In order to maintain the temperature of the frying oil, the frying oil needs to be circulated and heated. The frying oil can be extracted and filtered by the axial oil pump 24. The filtered frying oil and the oil squeezed out of the oil residue are collected through the four-way pipe 30 and then pumped to the heating barrel 20 for heating, so that the frying oil can be recycled and the utilization rate of the frying oil is improved.

[0034] In this embodiment, a support frame 16 with an L-shaped structure is fixedly installed on the top of the frying box 2, and a driving bevel gear 7 is rotatably installed at the bottom of one end of the support frame 16. The rotation center of the bottom of the driving bevel gear 7 is fixedly installed with the top of the main shaft 8 through a connecting shaft. A driven bevel gear 13 is rotatably installed on one side of the support frame 16. The driven bevel gear 13 is meshed with the driving bevel gear 7. A cam 12 is fixedly installed on one side of the driven bevel gear 13. A second turntable 14 is rotatably installed on the other side of the support frame 16. One side of the second turntable 14 is fixedly installed with the rotation center of one side of the driven bevel gear 13 through a connecting shaft. A first connecting rod 15 is rotatably installed on the edge of one side of the second turntable 14. A first waist slot hole is opened on the surface of the first connecting rod 15. A first waist slot hole is rotatably installed on one side of the support frame 16. A second connecting rod 17 is installed, and a second cam is fixedly installed on the top of one side of the second connecting rod 17. The second cam is slidably installed in the first waist slot hole. A second waist slot hole is opened at the bottom end of one side of the second connecting rod 17. The second connecting rod 17 is slidably sleeved on the surface of the first cam through the second waist slot hole. Two second limiting grooves are symmetrically opened on the surface of the transmission sleeve 9. A first turntable 10 is rotatably installed in the middle of the top of the frying box 2. A limiting hole adapted to the transmission sleeve 9 is opened on the top of the first turntable 10. A first spring rod 11 is fixedly installed on one side of the top of the first turntable 10. An adapter plate 40 is fixedly installed on the telescopic end of the first spring rod 11. One side of the adapter plate 40 is fixedly installed with the transmission sleeve 9, and the top of the adapter plate 40 is against the cam 12.

[0035] During use, the rotation of the main shaft 8 can drive the transmission sleeve 9 to rotate, and then drive the multi-layer storage drawer 27 in the frying box 2 to rotate. The rotation of the main shaft 8 simultaneously drives the driving bevel gear 7 to rotate, and the driving bevel gear 7 drives the driven bevel gear 13 to rotate. The driven bevel gear 13 drives the second turntable 14 to rotate, and then drives the scraper 21 to slide back and forth in the filter box 22 through the first connecting rod 15 and the second connecting rod 17, thereby driving the scraper 21. The rotation of the driven bevel gear 13 drives the cam 12 to rotate at the same time, and then intermittently compresses the second spring rod 11 through the adapter plate 40. Each time the spring rod 11 is reset, the transmission sleeve 9 is driven to slide upward along the main shaft 8 to a certain height through the adapter plate 40. By setting the first turntable 10 to rotate with the transmission sleeve 9, the first spring rod 11 is driven to rotate synchronously. Through the limited sliding relationship between the transmission sleeve 9, the main shaft 8 and the first turntable 10, the storage drawer 27 can be rotated and bumped up and down, so that the material can be more fully contacted with the hot oil during the frying process, avoiding uneven heating and improving the frying quality. The operation of the storage drawer 27 can also make the material distribution more even during the feeding process, avoiding local accumulation of material, which is not conducive to its full contact with the hot oil, thereby improving the linkage of the equipment.

[0036] In this embodiment, an isolation chamber is provided on one side of the frying box 2, a screw rod 3 is rotatably installed in the isolation chamber, and a moving block 28 with an inverted L-shaped structure is slidably installed in the isolation chamber. One end of the screw rod 3 passes through the outer surface of the moving block 28 and is threadedly connected to it. A through hole is opened on one side of the top of the moving block 28, and a feed pipe 5 is fixedly installed in the through hole. A feed funnel 4 is fixedly installed on the top of the feed pipe 5. The bottom end of the feed pipe 5 passes through the top of the frying box 2 and is slidably connected to it. A discharge box 38 is fixedly installed at the bottom of the feed pipe 5, and the discharge box 38 is opened on the side close to the main shaft 8. The feeding port of the surface structure, the drainage trough block 39 is slidably installed at the bottom of the feeding box 38, and a second spring rod 37 is fixedly installed on one side of the bottom of the feeding box 38. The telescopic end of the second spring rod 37 is fixedly installed on one side of the drainage trough block 39. A feeding port is provided on the surface of the frying box 2, and a sealing door 6 is hinged in the feeding port. The first motor 25 and the second motor 26 are fixedly installed at the bottom of the equipment box 1. The first motor 25 and the second motor 26 are respectively connected to the bottom end of the screw 3 and the main shaft 8 through a coupling, and an exhaust port for exhausting air is provided on the surface of the frying box 2.

[0037] During use, the moving block 28 is driven to slide by the rotation of the screw rod 3, and then the food to be fried can be delivered to the surface of each layer of the storage drawer 27 through the cooperation of the discharge box 38 and the drainage trough block 39. The drainage trough block 39 can lengthen the horizontal conveying distance of the discharge box 38. Combined with the rotation and bumping of the storage drawer 27, the material can be more evenly distributed on the surface of the storage drawer 27, avoiding the need to manually stack the material evenly, reducing manual labor and improving the processing efficiency of the equipment.

[0038] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the food to be fried is evenly laid on the surface of each layer of the storage drawer 27 through the feeding mechanism, avoiding the need to manually place the food layer by layer, making the frying process more efficient; then the frying box 2 is vacuumed by a vacuum machine, and a low-temperature vacuum frying method is adopted. During the frying process, a filter box 22 and two collection boxes 23 are provided, and an oil pump 24 is used to extract the frying oil from the frying box 2. The filter plate 35 in the filter box 22 can filter the oil residue in the frying oil, and the scraper 21 reciprocates to remove the oil residue. The sliding movement can scrape off the oil residue on the surface of the filter plate 35 to prevent the oil residue from clogging the filter plate 35, thereby improving the smoothness of the oil circuit of the equipment; the scraper 21 pushes the oil residue into the collecting box 23. When the scraper 21 moves away, the squeezing block 32 in the collecting box 23 squeezes the oil residue under the action of multiple return springs 34, squeezes out the excess frying oil, and flows it into the circulating oil circuit to avoid frying oil waste. The oil residue is collected in the residue collection drawer 36 and waits for centralized processing, effectively preventing the oil residue from participating in the frying operation again and damaging the appearance and taste of the fried food, thereby improving the energy saving effect of the equipment and the quality of the fried food.
