Description

Technical Field

[0001] This invention relates to a frying apparatus, and more particularly to a frying apparatus for processing aquatic products. Background Technology

[0002] Deep frying is a common process in the deep processing of aquatic products. For example, products such as crispy fish and crispy fish bones require deep frying during production. Currently, deep frying aquatic products presents problems such as difficulty in turning them over and easy sticking together. At the same time, the crumbs produced during frying remain in the oil, and repeated frying will cause them to burn, darken the oil color, and give it a burnt taste, affecting the flavor of the product.

[0003] Chinese Patent Application Publication No. CN117530303A, published on February 9, 2024, discloses an anti-sticking and temperature control device for fried prepared foods. The device includes a base, a mounting frame on the base, a rotating rod rotatably passing through the mounting frame, a frying box fixedly mounted on the rotating rod, a controller, a temperature sensor, an oil testing instrument, and a heater fixedly mounted on the frying box, and a stirring mechanism on the base. The stirring mechanism includes a mounting plate fixedly mounted on the base, a second rotary motor fixedly mounted on the mounting plate, and an electric telescopic rod fixedly mounted at the rotating end of the second rotary motor passing through the mounting plate. Multiple stirring rods are fixedly mounted at the bottom of the electric telescopic rod. This device prevents fried prepared foods from sticking together by moving the frying box and stirring with the stirring rods. However, it has the following drawbacks: (1) it cannot clean up residue in the oil; (2) the stirring rods rotate horizontally in a circular motion, failing to fully stir the materials, leading to easy sticking between materials and between the materials and the inner wall of the frying box; (3) discharging is inconvenient. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned problems existing in the existing frying and seasoning food devices, and provides a frying device for aquatic product processing that is simple in structure, convenient in discharging, does not easily cause materials to stick together during frying, and leaves little residue in the oil.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A deep-frying device for aquatic product processing according to the present invention includes a support, an oil tank, and a turning mechanism. The oil tank is fixed on the support, and a heating tube is provided inside the oil tank. A frying basket is provided inside the oil tank, and the frying basket is hinged to the oil tank. The turning mechanism is set on the support and connected to the frying basket. The turning mechanism drives the frying basket to turn around the hinge point as the axis. An elastic feeding mechanism is provided at the bottom of the frying basket. The elastic feeding mechanism includes a swing spring and a feeding rod. The lower end of the swing spring is fixedly connected to the frying basket, and the upper end of the swing spring is fixedly connected to the feeding rod. In this invention, the flipping mechanism drives the frying basket to flip around the hinge point, allowing the basket to switch between a flipped state and a horizontal state. When the basket is horizontal, it is located in the oil tank for frying; when it is flipped, it is detached from the oil tank for discharge. The flipping mechanism enables automatic discharge, which is convenient. The debris generated during frying is intercepted in the basket and discharged during discharge, keeping the oil in the tank clean. The swing spring can swing and bend arbitrarily in the horizontal direction and can be compressed or stretched in the vertical direction. When frying, the oil bubbles and rolls, causing the swing spring to shake, which in turn causes the feeding rod to move or disturb the material in the basket, dispersing the material and preventing it from sticking together. The feeding rod also acts as a heat conductor, which helps the oil heat up quickly and keeps the oil temperature in the basket uniform.

[0006] Preferably, the bottom of the frying basket is provided with a spring limiting seat, the lower part of the feeding rod is provided with a limiting section, the limiting section and the feeding rod form a limiting step, the lower part of the swing spring is sleeved outside the spring limiting seat, and the upper part of the swing spring is sleeved outside the limiting section and abuts against the limiting step.

[0007] Preferably, the tip of the feeding rod is hemispherical. A hemispherical tip, without sharp edges, avoids damage to the material.

[0008] Preferably, the flipping mechanism includes two flipping cylinders, which are respectively disposed on both sides of the support. The cylinder body of the flipping cylinder is hinged to the support. Fixed shafts are provided on both sides of the frying basket. The piston rod end of the flipping cylinder is rotatably connected to the fixed shaft.

[0009] Preferably, the frying basket is provided with connecting shafts on both sides, and the support is provided with bearing seats, and the connecting shafts are rotatably connected to the bearing seats.

[0010] Preferably, the inner wall of the frying basket is provided with anti-sticking ribs spaced apart from top to bottom, and the cross-section of the anti-sticking ribs is triangular. The anti-sticking ribs in this invention can block materials, reduce the contact area between the materials and the frying basket, and thus reduce the probability of materials sticking to the inner wall of the frying basket.

[0011] Preferably, the anti-sticking rib has a hollow structure and is provided with convection impact holes. Oil can enter the anti-sticking rib and then flow out from the convection impact holes to form an impact flow, thereby causing a slight impact on the material and dislodging it from the inner wall of the frying basket, preventing the material from sticking to the inner wall of the frying basket.

[0012] Preferably, the frying basket is provided with a material guide trough on one side, and the material guide trough has a "U" shaped cross section.

[0013] Preferably, the oil tank is equipped with a mounting bracket, and the mounting bracket is equipped with a lifting cylinder. A lifting pressure plate that can extend into the oil tank is fixed to the piston shaft end of the lifting cylinder. The lifting pressure plate includes a frame and a perforated plate fixed within the frame, and a connecting plate is provided on the perforated plate. Before discharge, the lifting pressure plate descends and extends into the frying basket to block the material, preventing material from accumulating downwards and causing pressure when the frying basket is turned over. Simultaneously, it blocks the material during discharge, providing a limiting and guiding function. The connecting plate is used to connect the piston rod of the lifting cylinder.

[0014] Preferably, a limiting plate is fixed at the bottom of the oil tank. The limiting plate serves to limit the movement of the lifting pressure plate.

[0015] Therefore, the present invention has the following beneficial effects:

[0016] (1) The bottom of the frying basket is equipped with an elastic feeding mechanism. During frying, the feeding mechanism can move or disturb the material in the frying basket to disperse the material and prevent it from sticking together.

[0017] (2) Through the cooperation between the flipping mechanism, the frying basket and other structures, automatic discharge after frying can be achieved;

[0018] (3) The material is deep-fried in the frying basket, which can intercept the debris and keep the oil in the oil tank clean. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 , Figure 2 The above-described aquatic product processing frying device includes a support frame 1, an oil tank 2, and a turning mechanism. The oil tank is fixed on the support frame, and a heating pipe 3 is installed inside the oil tank. A frying basket 4 is provided inside the oil tank. Anti-sticking ribs 14 are spaced apart from top to bottom on the inner wall of the frying basket. The anti-sticking ribs have a triangular cross-section and a hollow structure. Convection impact holes 15 are provided on the anti-sticking ribs (e.g., Figure 4 (As shown), the flipping mechanism drives the frying basket to flip around the hinge point as the axis. The flipping mechanism includes two flipping cylinders 10, which are respectively set on both sides of the support. The cylinder body of the flipping cylinder is hinged to the support. Fixed shafts 11 are provided on both sides of the frying basket. The piston rod end of the flipping cylinder is rotatably connected to the fixed shaft. Connecting shafts 12 are fixed on both sides of the frying basket. Bearing seats 13 are fixed on the support. The connecting shafts are rotatably connected to the bearing seats. A guide groove 16 is provided on one side of the frying basket (the side of the connecting shaft). The cross-section of the guide groove is "U". An elastic feeding mechanism is provided at the bottom of the frying basket. The elastic feeding mechanism includes a swing spring 5 and a feeding rod 6 (such as...). Figure 3 As shown), the top of the feeding rod is hemispherical, the bottom of the frying basket is provided with a spring limiting seat 7, the lower part of the feeding rod is provided with a limiting section 8, and a limiting step 9 is formed between the limiting section and the feeding rod. The lower part of the swing spring is sleeved outside the spring limiting seat, and the upper part of the swing spring is sleeved outside the limiting section and abuts against the limiting step. The oil tank is provided with a mounting bracket 17, and the mounting bracket is provided with a lifting cylinder 18. The piston shaft end of the lifting cylinder is fixed with a lifting pressure plate 19 that can extend into the oil tank. The lifting pressure plate includes a frame 20 and a perforated plate 21 fixed in the frame (e.g., Figure 5 As shown), the perforated plate is provided with a connecting plate 22 for connecting the piston shaft of the lifting cylinder, and a limit plate 23 is fixed at the bottom of the oil tank.

[0027] The method of using this invention is as follows: the oil is heated by the heating tube. When the oil reaches the predetermined temperature, the material (fish) is added to the frying basket for frying. After frying, the piston rod of the lifting cylinder extends, so that the perforated plate extends downward into the frying basket. Then the piston rod of the flipping cylinder extends, the frying basket rotates around the fixed shaft and gradually moves away from the frying basket. After the frying basket flips to the set position, the piston rod of the lifting cylinder retracts, and the material falls into the guide chute and slides down along the guide chute.
