Detailed Embodiments

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0017] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0018] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. This embodiment is written in a progressive manner.

[0019] As Figures 1 to 5 shown, a food frying treatment device of the present invention includes: A frying tank 1; An oil storage chamber 2 for storing oil liquid, and the oil storage chamber 2 is opened at the bottom of the frying tank 1; A conveying unit 3 located inside the frying tank 1 and used for horizontally conveying food. When the conveying unit 3 conveys food, the food undergoes a tumbling motion; An oil spraying unit 4 located above the conveying unit 3 inside the frying tank 1, and used for pumping out the oil liquid in the oil storage chamber 2 and spraying high-temperature oil liquid onto the food on the conveying unit 3; Among them, the frying tank 1 is horizontal, and a feeding channel 5 for feeding is provided on one side of the frying tank 1, and a discharging channel 6 for discharging is provided on the other side of the frying tank 1.

[0020] In detail, the bottom surface of the frying box 1 is conical, and the lowest point of the cone is located at the top of the oil storage chamber 2, so that the excess oil sprayed by the oil spray unit 4 can flow back into the oil storage chamber 2 through the conical surface, so as to realize the recycling of the oil. The oil in the oil storage chamber 2 is high-temperature oil, and an electric heating structure can be provided in the oil storage chamber 2 to heat the oil. The conveying unit 3 and the oil spray unit 4 are respectively located at the upper and lower sides of the inside of the frying box 1. The conveying unit 3 can convey the food horizontally, and the conveying unit 3 can make the food itself tumble when conveying the food, so that the oil discharged by the oil spray unit 4 can fully cover the surface of the food, thereby fully frying the food, and the excess oil will directly fall to the lower side of the inside of the frying box 1 and flow into the oil storage chamber 2, thereby making it convenient to retain only a thin layer of oil on the surface of the food, and the oil discharged by the conveying unit 3 will fall on the surface of the food, and the excess oil on the surface of the food will naturally drip, thereby continuously replacing the oil layer on the surface of the food, and the high-temperature oil layer fully fries the food.

[0021] It should be pointed out that, since only a thin layer of oil is retained on the surface of the food, the volatile gas inside the food can quickly pass through the oil layer and be discharged when the food is fried, so as to avoid the oil blocking the gas, facilitate the maturation of the food, and avoid the dangerous phenomenon of a large amount of oil splashing when the bubbles formed by the gas in the oil burst in the traditional frying method. This oil-spraying frying method can also ensure the crispy effect on the surface of the food and avoid food aging caused by too long frying time. The feed channel 5 is installed on the upper surface of one side of the frying box 1. The feed channel 5 can continuously convey food to the conveying unit 3. The fried food can be discharged through the discharge channel 6, thereby realizing the continuous and automatic frying of the food. Since the oil-spraying frying method is adopted, the use of oil can be greatly reduced, reducing consumption.

[0022] In actual use, a filtering unit may be provided between the oil storage chamber 2 and the oil injection unit 4 to achieve purification and filtration of the oil.

[0023] By utilizing the conveying unit 3 and the oil spraying unit 4 to realize the continuous conveying and frying processing of food, the production efficiency is greatly improved, the production cycle is shortened, and the use of oil spraying frying instead of traditional immersion frying can significantly reduce the amount of oil used, reduce oil waste, and reduce operating costs; by making the food turn over during transportation, it is ensured that the oil evenly covers the surface of the food, avoiding the phenomenon of food burning caused by local overheating, and in this way, only a thin layer of oil is retained on the surface of the food.

[0024] Further, the bottom opening position of the feeding channel 5 is close to the upper surface of the conveying unit 3. A notch 7 is provided on one side of the bottom opening position of the feeding channel 5 facing the conveying direction of the conveying unit 3. The notch 7 is used to lay a layer of food on the upper surface of the conveying unit 3.

[0025] Specifically, by adopting the structural method of providing the notch 7 on the feeding channel 5, it is convenient to limit the amount of food passing through the notch 7, so that at most one layer of food is laid on the upper surface of the conveying unit 3. In this way, it is convenient to fry the entire surface of the food. When there are multiple layers of food on the conveying unit 3, the food blocks each other, and the conveying unit 3 cannot drive the food to flip, resulting in the inability to fully fry the food.

[0026] Further, the oil spraying unit 4 includes a pump body 12 installed on the side wall of the frying tank 1. Oil pipelines 13 are provided at both the input end and the output end of the pump body 12. The oil pipeline 13 at the input end of the pump body 12 is communicated with the oil storage chamber 2. A diverting oil pipeline 14 is fixed to the top of the inner wall of the frying tank 1. The oil pipeline 13 at the output end of the pump body 12 is communicated with the diverting oil pipeline 14. A plurality of nozzles 15 for spraying oil outward are provided on the diverting oil pipeline 14.

[0027] Specifically, the pump body 12 can introduce the oil stored in the oil storage chamber 2 into the diverting oil pipeline 14 through the two oil pipelines 13, and the diverting oil pipeline 14 sprays the oil downward onto the food on the conveying unit 3 through the plurality of nozzles 15.

[0028] Further, the shape of the diverting oil pipeline 14 is wavy. The position where one end of the diverting oil pipeline 14 is communicated with the oil pipeline 13 at the output end of the pump body 12 is located on the side far from the feeding channel 5, and the other end of the diverting oil pipeline 14 is located on the side close to the feeding channel 5.

[0029] Specifically, the oil enters the diverting oil pipeline 14 from the end far from the feeding channel 5. In this way, the oil flows in the diverting oil pipeline 14 from the side far from the feeding channel 5 towards the side close to the feeding channel 5. That is, the temperature of the oil in the diverting oil pipeline 14 gradually decreases as it gets closer to the feeding channel 5. The temperature of the oil for frying the food gradually increases as the food moves. Thus, the working process of gradually increasing the temperature for frying is realized, rather than directly frying the food at a relatively high temperature, which is convenient for the food to be heated evenly inside and outside.

[0030] Since the shape of the diverting oil pipeline 14 is wavy, the oil in the diverting oil pipeline 14 can flow in a wavy shape. This can extend the flow path of the oil, provide time for the oil to cool down, and at the same time increase the number of nozzles 15 arranged.

[0031] Further, the conveying unit 3 includes two side plates 16 distributed left and right and a plurality of supporting columns 17 located between the two side plates 16. The side plates 16 are in the shape of a horizontal capsule, and the plurality of supporting columns 17 are arranged along the outer contour of the side plates 16. Gears 18 are provided at both ends of the supporting columns 17; Teeth are provided on the outer wall of the side plate 16, and the gears 18 mesh with the teeth on the side plate 16. When the gears 18 move along the outer contour of the side plate 16, the supporting columns 17 move synchronously and rotate; Wherein, the side plate 16 is fixed on the inner wall of the frying tank 1.

[0032] Specifically, the plurality of supporting columns 17 perform a circular motion around the side plate 16. The plurality of supporting columns 17 are used to carry food. In this way, when the supporting columns 17 move, they will drive the food to move synchronously, thereby realizing the horizontal conveying of the food. And because the supporting columns 17 rotate synchronously, the supporting columns 17 can drive the food to perform a tumbling motion, thus realizing the conveying and tumbling motion modes of the food.

[0033] Further, two transmission rollers are provided between the two side plates 16. The two transmission rollers are driven by two transmission chains 20. The two transmission chains 20 correspond to the two side plates 16 respectively. A plurality of pull rods 21 are provided on the transmission chain 20. A connecting plate 22 is provided on the pull rod 21, and the pull rod 21 and the connecting plate 22 are rotatably connected. The connecting plate 22 is rotatably connected to the supporting column 17. A sliding column 23 is provided on the connecting plate 22; A guiding groove 24 having the same shape as the outer contour of the side plate 16 is formed on the side wall of the side plate 16. The sliding column 23 is slidably installed in the guiding groove 24. A motor 19 is provided on the outer wall of the frying tank 1, and the motor 19 is drivingly connected to one of the transmission rollers.

[0034] Specifically, the motor 19 can drive the two transmission rollers and the two transmission chains 20 to move synchronously. The transmission chain 20 can pull the supporting column 17 to move through the pull rod 21 and the connecting plate 22, so that the gear 18 rolls on the side plate 16. At the same time, the connecting plate 22 will drive the sliding column 23 to slide in the guiding groove 24, thereby using the sliding column 23 and the guiding groove 24 to limit and guide the notch 7.

[0035] Further, a roller 8 is rotatably provided at the bottom of the notch 7; A rotating column 9 is rotatably embedded on the upper surface of the frying tank 1. The feeding channel 5 passes through the rotating column 9 and is fixedly connected. A limiting plate 10 is fixed on the frying tank 1. The limiting plate 10 abuts against the side wall of the feeding channel 5, and the limiting plate 10 and the feeding channel 5 are connected by an elastic piece 11; Wherein, when the conveying unit 3 operates, each supporting column 17 on it will push the feeding channel 5 to tilt when moving to the position of the roller 8.

[0036] Specifically, when the supporting column 17 moves to the bottom of the feeding channel 5, the supporting column 17 contacts the roller 8 and pushes the feeding channel 5 to tilt through the roller 8. At this time, the feeding channel 5 drives the rotating column 9 to rotate on the frying tank 1, and the feeding channel 5 separates from the limiting plate 10, and the elastic piece 11 undergoes elastic deformation. When the supporting column 17 separates from the roller 8, the elastic piece 11 pushes the feeding channel 5 to reset and contact the limiting plate 10 again. When the next supporting column 17 moves to the position of the roller 8, it will push the feeding channel 5 to tilt again. Thus, by using the continuous rotary motion of multiple supporting columns 17 on the conveying unit 3, the vibration of the feeding channel 5 is realized, which facilitates the vibration and scattering of the food in the feeding channel 5 onto the conveying unit 3 and avoids the blockage of the food in the feeding channel 5.

[0037] Furthermore, two outer edges are provided on the outer wall of the side plate 16, and the gear 18 moves between the two outer edges; The conveying unit 3 further includes two baffles 25, and the two baffles 25 are located on both sides of the supporting column 17 in the length direction. The baffles 25 are fixed to the inner wall of the frying tank 1 through the supporting plates 26.

[0038] Specifically, the outer edges on the side plate 16 can limit and guide the gear 18, thereby cooperating with the sliding column 23 and the guiding groove 24 to limit the position of the supporting column 17. The baffle 25 can block the food on the supporting column 17, so as to ensure the stable conveyance of the food on multiple supporting columns 17 of the conveying unit 3, avoid the food from rolling to the position of the gear 18 and affecting the normal operation of the gear 18. The supporting plate 26 can support the baffle 25, and the supporting plate 26 can shield multiple gears 18.

[0039] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
