Description

Technical Field

[0001] The present application relates to the technical field of food processing machinery, and in particular to an automatic frying device for fried food. Background Art

[0002] Deep-frying is a cooking method. Over-frying produces polycyclic aromatic hydrocarbons (PAHs). Whether it's fried dough twists, spring rolls, or meatballs enjoyed during festivals, or the fried dough sticks, fried cakes, and flatbreads we eat for breakfast every day, or the French fries, fried bread, and fried chicken wings in fast food popular with children, or the potato chips and biscuits we eat as snacks, all are fried foods.

[0003] Fried dough sticks (youtiao), a traditional Chinese breakfast snack, are long, crispy, and chewy. They're a favorite among nearly every Chinese. Deep-frying them is simple: place the cold dough (fermented, long, doughy dough) in a pan and deep-fry until golden brown.

[0004] Currently, fried dough sticks are mostly made manually. This process limits workers' working time, and repetitive work can lead to fatigue, reduced efficiency, and an inability to guarantee the quality of each product. Furthermore, related food frying equipment has also emerged, but most existing equipment is assembly-line-style. Stainless steel mesh cages are fixed to a conveyor chain, or the cold dough sticks are placed directly on a conveyor chain with the middle of the chain immersed in the frying equipment. The conveyor chain transports the cold dough sticks into hot oil for frying and then drains them out of the conveyor chain. However, with this type of equipment, the cold dough sticks still need to be completely immersed in the hot oil during frying, resulting in a high amount of residual oil, which does not meet the growing demand for healthy, low-fat foods. Furthermore, this fully submerged frying method also easily leaves a large amount of dough residue in the hot oil. Furthermore, this frying method often requires prolonged use of hot oil, and prolonged frying of pasta can produce substances such as acrylamide, trans fats, and benzopyrene, which can seriously harm human health.

[0005] Therefore, there is an urgent need in the art for an automatic fried dough stick cold embryo frying machine that can automatically perform fried dough stick cold embryo frying without immersing the fried dough stick cold embryo as a whole in hot oil and can clean residue at any time. Utility Model Content

[0006] In order to realize the automatic frying processing of the cold dough sticks, there is no need to immerse the cold dough sticks in hot oil as a whole, and the residue can be cleaned at any time to reduce the possibility of the residue producing harmful substances that affect human health.

The heating pipe is a serpentine heat exchange pipe laid in the hot oil tank. The heating wire is arranged in the heating pipe and electrically connected to an external power supply. The filter element is detachably arranged on the top wall of the hot oil tank.

[0010] Furthermore, the hot shower mechanism includes a suction pump, an upper hot shower pipe, a lower hot shower pipe and a spray head. The liquid inlet of the suction pump is connected to the hot oil tank. The upper hot shower pipe and the lower hot shower pipe are respectively arranged on the frying box and are connected to the liquid outlet of the suction pump through a connecting pipe. The conveying mechanism is located between the upper hot shower pipe and the lower hot shower pipe. Multiple spray heads are evenly spaced on the upper hot shower pipe and the lower hot shower pipe along the conveying direction of the conveying mechanism, and the spray heads are arranged toward the conveying mechanism.

[0011] Furthermore, the upper hot shower pipe and the lower hot shower pipe are respectively arranged on the outer wall of the frying box, and a plurality of spray branch pipes are evenly spaced on the upper hot shower pipe and the lower hot shower pipe along the conveying direction of the conveying mechanism.

[0025] The following is combined with Figure 1-2 This application is described in further detail.

[0026] The embodiment of the present application discloses an automatic frying device for fried foods.

[0027] Reference Figure 1 and Figure 2 An automatic frying device for fried food includes a frying box 1, a conveying mechanism 2, a hot oil device 3, and a hot shower mechanism 4. The frying box 1 is a hollow box for frying food. The conveying mechanism 2 is installed on one side of the frying box 1 and penetrates the frying box 1 for conveying the fried food throughout the frying process. The hot oil device 3 is installed on one side of the frying box 1 for heating the frying oil. An oil outlet 11 connected to the hot oil device 3 is integrally formed on the side wall of the frying box 1. The oil outlet 11 is "L"-shaped to drain the oil downward and also facilitate subsequent cleaning operations.

[0028] The hot shower mechanism 4 is installed on one side of the frying box 1 and connects the inner cavity of the frying box 1 and the hot oil device 3. It is used to send the hot oil in the hot oil device 3 into the frying box 1 and spray it in multiple ranges in the frying box 1 to fry the food. The oil outlet 11 can realize the recycling of the hot oil. At least one filter element 10 is installed between the oil outlet 11 and the hot oil device 3 to circulate and filter the recycled hot oil, thereby reducing the possibility of frying oil residue remaining in the oil body and producing harmful substances during long-term frying.

[0029] Reference Figure 1 and Figure 2 The hot oil device 3 includes a hot oil tank 31, a heating pipe 32 and a heating wire 33. The hot oil tank 31 has an open top and a plurality of universal wheels 5 with locks are installed on the bottom wall to facilitate the movement of the hot oil tank 31. The heating pipe 32 is a serpentine heat exchange pipe installed in the hot oil tank 31. The heating wire 33 is installed in the heating pipe 32 and is electrically connected to an external power supply.

[0030] When in use, the hot oil tank 31 moves to the bottom of the oil outlet 11, the power supply is supplied, the current flows through the heating wire 33 to generate heat and then transfers the heat to the heating tube 32, and the heating tube 32 heats the edible oil in the hot oil tank 31 to provide the hot oil required for frying. The filter element 10 is a filter mesh, which is detachably mounted on the top wall of the hot oil tank 31 by bolts to filter the oil flowing from the oil outlet 11 into the hot oil tank 31. In this embodiment, the filter element 10 can be a whole filter mesh with equal surface area on the hot oil tank 31, or it can be multiple filter meshes installed separately. The heating principle of the heating wire 33 is existing technology and will not be described in detail.

[0031] Reference Figure 1 and Figure 2 The conveying mechanism 2 includes a loading component 21 and a frying feeding component 22. The loading component 21 is used to load the cold dough bar embryos waiting for frying, and the frying feeding component 22 is used to feed the cold dough bar embryos waiting for processing into the frying box 1 for frying;

[0032] Specifically, the loading component 21 is a conventional conveyor belt, and the transmission belt body on the conveyor belt is preferably a silicone belt body, which can prevent the cold pasta embryo from sticking; the frying feeding component 22 is a spring wire conveyor belt driven by a gear chain, which can facilitate the multi-range spray frying of the hot shower mechanism 4 when the cold pasta embryo enters the frying box 1.

[0033] Reference Figure 1 and Figure 2 The hot shower mechanism 4 includes a suction pump 41, which is installed on one side of the frying box 1 through a lifting support 6. It can be fine-tuned in height and can be carried at any time to adapt to the movement of the hot oil tank 31 and the connection with the hot oil tank 31. The liquid inlet of the suction pump 41 is connected to the hot oil tank 31 through a flange, and a stop valve 8 is installed between the liquid inlet of the suction pump 41 and the hot oil tank 31 to facilitate the on-off and flow control of the suction pump 41.

[0034] Furthermore, the hot shower mechanism 4 also includes an upper hot shower pipe 42, a lower hot shower pipe 43 and a spray head 44. The upper hot shower pipe 42 and the lower hot shower pipe 43 are respectively arranged on the outer wall of the frying box 1 and are connected to the liquid outlet of the suction pump 41 through a connecting pipe 7. The frying feeding assembly 22 is located between the upper hot shower pipe 42 and the lower hot shower pipe 43. The upper hot shower pipe 42 and the lower hot shower pipe 43 are both evenly spaced along the conveying direction of the conveying mechanism 2. A plurality of spray branches 45 are evenly spaced along the length direction of the spray branches 45. The spray heads 44 are arranged toward the conveying mechanism 2, thereby realizing hot oil spraying from the upper and lower sides of the cold pasta embryo in the process of feeding the cold pasta embryo, so that the cold pasta embryo is heated evenly during frying.

[0035] Specifically, the spray branch pipe 45 is integrally formed with the upper hot shower pipe 42 and the lower hot shower pipe 43. A plurality of plug holes are provided on the outer wall of the frying box 1. The spray branch pipe 45 is inserted into the frying box 1 through the plug holes. The connecting pipe 7 can also realize the fixation of the upper hot shower pipe 42 and the lower hot shower pipe 43 on the frying box 1.

[0037] Furthermore, a flow sensor may be installed on the connecting pipe 7 to monitor the circulation flow of the hot oil so that the operator can adjust the hot oil flow through the stop valve 8 at any time.

[0038] Furthermore, a liquid level sensor 9 is installed in the hot oil tank 31, and a refueling port 311 is integrally formed on the outer wall of the hot oil tank 31 and is connected to an external automatic liquid adding device. The liquid level sensor 9 is connected to the external automatic liquid adding device by signal. During the frying process of cold pasta dough, the hot oil will be consumed due to the frying of pasta, so the hot oil in the hot oil tank 31 will become less and less. Through the setting of the liquid level sensor 9 and the refueling port 311, edible oil can be automatically replenished during the food processing process, thereby greatly improving the processing efficiency.

[0039] Reference Figure 1 and Figure 2 , refer to Figure 1 and Figure 2 A cover 12 is hingedly installed on the top of the frying box 1, and a plurality of smoke exhaust ports 121 are integrally formed on the cover 12 to discharge the smoke oil in time during frying; a receiving groove 13 is opened on the bottom wall of the frying box 1, and the hot oil tank 31 can be pushed into or pulled out of the receiving groove 13 to facilitate the storage of the hot oil device 3 when the frying equipment is refurbished.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
