Description

Technical Field

[0001] This utility model relates to the field of industrial processing equipment for food, specifically to a continuous frying equipment for food processing. Background Technology

[0002] In the food processing industry, frying is a common method, especially in the production of easily puffed foods such as potato chips, extruded puffed foods, and snack noodle products, where frying can impart unique textures and flavors. However, traditional frying equipment has many limitations in design and function, which to some extent restrict the efficiency of food processing and product quality.

[0003] Existing frying equipment typically has a simple structure and relatively primitive operation, often involving direct frying in an open oil pan. During frying, operators place the food in a wire basket and then directly lower the basket into the oil. After frying, the basket is removed along with the food to complete the process. This method is not only labor-intensive and inefficient, but also results in uneven temperature distribution during frying, as the food often floats on the surface and constantly tumbles. This uneven temperature can lead to incomplete frying, affecting not only the taste and appearance of the food but also food safety and hygiene.

[0004] In addition, this type of traditional frying equipment lacks automated continuous processing capabilities. It cannot achieve rapid and uniform frying of ingredients, and the frying time is difficult to control precisely. It also cannot achieve continuous feeding and discharging, which further limits the flexibility and application scope of frying equipment in food processing.

[0005] For the reasons mentioned above, it is necessary to design a new continuous frying equipment suitable for industrial food processing to improve the automation level of frying equipment and ensure the uniformity of frying results and the safety of food. Utility Model Content

[0014] As a further limitation, the length ratio of the feeding section, the frying section and the discharging section in the frying cavity is 1:2:1, so that the food can be heated evenly in the frying cavity and the frying efficiency can be improved.

[0015] As a further limitation, the inner wall of the blasting chamber, the spiral blades of the spiral conveyor, and the mesh cover are all made of 316 stainless steel or coated with Teflon.

[0016] As a further limitation, a scraper conveyor is provided at the discharge port as a discharge device, and the scraper conveyor has a perforated surface; and a downward blowing filter device is also installed on the upper part of the scraper conveyor.

[0017] As a further limitation, the frying chamber is provided with a slag discharge port on the bottom outer side of the discharge section, and a residue filtering device is also provided at the slag discharge port.

[0018] As a further limitation, the drive shaft of the screw conveyor extends from the outside of the feeding section into the frying section, and its length matches the sum of the lengths of the feeding section and the frying section;

[0019] The screw conveyor is a two-stage screw structure, including a main screw blade set in the feeding section and an auxiliary screw blade set in the frying section. The main screw blade and the auxiliary screw blade have different pitches, and the main screw blade and the auxiliary screw blade are driven by different independent rotating shafts.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0028] See Figure 1 , Figure 2A preferred embodiment of a continuous frying equipment for food processing is provided. In this embodiment, the equipment includes a frame 13, which is a split steel structure support. The front support supports the feeding section 15 and the frying section 12, while the rear support supports the discharging section 11. Adjustable feet are provided at the bottom of both the front and rear supports of the frame 13 to facilitate adjustment of the overall height and leveling of the equipment according to production needs.

[0029] A frying chamber is fixedly assembled on the frame 13. As the core component of the frying operation, the frying chamber in this embodiment consists of a separable feeding section 15, a frying section 12, and a discharging section 11. The feeding section 15, the frying section 12, and the discharging section 11 are formed independently. The feeding section 15 and the frying section 12, as well as the frying section 12 and the discharging section 11, are connected by flanges 5 with seals to ensure that the oil in the frying chamber will not leak. After the feeding section 15, the frying section 12, and the discharging section 11 are assembled, they form a continuous volumetric cavity structure that runs through the front and back as the frying chamber for the frying operation.

[0030] The separate assembly design of the feeding section 15, frying section 12, and discharging section 11 facilitates disassembly, cleaning, and daily maintenance of the equipment. In this embodiment, the length ratio of the feeding section 15, frying section 12, and discharging section 11 in the frying cavity is 1:2:1, which ensures that the food is heated evenly in the frying cavity and improves frying efficiency.

[0031] A feeding device is provided in the feeding section 15 of the frying chamber to continuously feed the food to be fried into the frying chamber. In this embodiment, the feeding device is a bucket-shaped feeding structure with a feeding port 3 at the top for feeding food and an oil filling port 14 on the side wall for replenishing the oil in the frying chamber.

[0032] A heating device is installed on the outside of the frying section 12 within the frying cavity to heat the oil inside. In this embodiment, the heating device uses electric heating elements, which are evenly distributed on the outside of the frying cavity to ensure uniform heating of the oil and improve frying results. Additionally, this embodiment also includes an oil temperature sensor and an oil level sensor in the frying section 12 to monitor the oil temperature and level in real time. The presence of these sensors allows operators to monitor the oil temperature and level in the frying section in real time, enabling timely adjustments if any abnormalities occur. This avoids uneven frying and poor frying results caused by excessively high or low oil temperatures or levels.

[0033] The top surface of the frying section 12 is open, and a mesh cover plate 4 is provided at the open top surface. The mesh cover plate 4 is located below the oil surface in the frying cavity. The mesh cover plate 4 can press the food into the oil surface in the frying cavity, so that the food can fully contact the hot oil and improve the frying efficiency.

[0034] In this embodiment, the cross-section of the frying cavity in the feeding section 15 is circular, and the outer end face of the feeding section 15 is an open surface with a flange assembly position reserved there. This flange assembly position is used to assemble and connect with the end face base on the outside through a flange 5 with a sealing element and maintain a seal. The end face base is equipped with a secondary shaft drive motor 1 and a main shaft drive motor 2. The cross-section combination of the concave volume cavity and the mesh cover plate 4 in the frying section 12 is also circular and is concentric with the cross-sectional circle of the frying cavity in the feeding section 15.

[0035] This concentric double-cylinder structure facilitates the installation of a screw conveyor as a feeding mechanism in the frying cylinder 23. In this embodiment, the screw conveyor is a two-stage screw conveyor, including a main screw blade 16 disposed in the feeding section 15 and a secondary screw blade 19 disposed in the frying section 12. The outer spiral contour of the main screw blade 16 matches the circular cross-sectional dimensions of the feeding section 15, while the outer spiral contour of the secondary screw blade 19 matches the circular cross-sectional dimensions formed by the concave volume cavity and the mesh cover plate 4 corresponding to the frying section 12.

[0036] The main helical blade 16 and the auxiliary helical blade 19 have different pitches to adapt to the movement requirements of the food at different stages within the frying chamber. The main helical blade 16 and the auxiliary helical blade 19 are driven by the main shaft 17 and the auxiliary shaft 18, respectively, which are driven by the main shaft drive motor 2 and the auxiliary shaft drive motor 1, respectively, to achieve independent rotation. The main helical blade 16 continuously pushes the food entering the frying chamber through the feeding device into the frying section 12 for frying, while the auxiliary helical blade 19 pushes the food in the oil within the frying section 12. This ensures that the food is heated evenly during frying, and the frying time in the frying section 12 can be strictly controlled by adjusting the pushing speed of the auxiliary helical blade 19. It also effectively prevents the food from sticking and piling up during frying, further improving the production efficiency and product quality of the frying equipment.

[0037] In this embodiment, the main spiral blade 16 and the auxiliary spiral blade 19 are evenly distributed with sieve holes. These sieve holes allow the oil in the frying chamber to flow and connect during the frying process, thereby generating localized eddies. This helps form a crispy outer layer on the food surface, improving the texture of the food. Furthermore, the sieve hole design also helps to stably transport the food on the spiral conveyor, preventing slippage or blockage during transport, further improving the operating efficiency and stability of the equipment.

[0038] In another embodiment, the frying section 12 has an open opening at the position corresponding to the mesh cover plate 4. In another embodiment, a smoke exhaust device mounting position can be reserved at the open opening position to facilitate the installation of the smoke exhaust device. The oil fumes can be effectively exhausted to the outside of the equipment through the smoke exhaust device, thereby improving the working environment of the operators and avoiding secondary pollution of food by oil fumes, further ensuring food safety and hygiene.

[0039] A discharge device is provided at the upper rear side of the discharge section 11 of the frying chamber. The main body of the discharge device is a scraper conveyor 7, which is fixedly mounted on the rear support of the frame 13 by a structural bracket. The scraper conveyor 7 is driven by a scraper conveyor drive motor 8 and receives the discharge port 9 at the rear.

[0040] The scraper conveyor 7 has a perforated surface, the upper surface of which matches the oil level in the frying chamber. The food that has been fried in the frying section 12 is pushed into the frying chamber of the discharge section 11 by the auxiliary spiral blades 19. Due to the characteristics of puffed fried food, it will float on the surface of the oil and then be lifted by the scraper of the scraper conveyor 7 and transported to the discharge port 9. The perforated surface design of the scraper conveyor 7 ensures that the food is transported without direct contact with the oil, preventing secondary frying during the discharge process and ensuring the taste and quality of the food. In addition, the perforated surface also has an oil-draining function, which can filter out excess oil from the food and further improve the frying quality of the food.

[0041] In order to optimize the oil removal effect on the food on the scraper conveyor 7, a downward blowing filter device 6 is also installed on the upper part of the scraper conveyor 7. The blowing filter device 6 can further remove the excess oil adhering to the surface of the food by blowing air onto the perforated belt surface of the scraper conveyor 7, reducing the greasiness of the food and avoiding the waste of oil.

[0042] In addition, a slag discharge port 10 is provided on the bottom outer side of the discharge section 11 of the frying chamber, and a residue filter device is also provided at the slag discharge port 10. The slag discharge port 10 facilitates the replacement and cleaning of the oil in the frying chamber, while the residue filter device cleans the fried residue in the frying chamber and collects and treats the discharged fried residue, thus avoiding environmental pollution from the residue.

[0043] In different embodiments, the inner wall of the frying chamber, the spiral blades of the spiral conveyor, and the mesh cover plate 4 are all made of 316 stainless steel or coated with Teflon to enhance the corrosion resistance and durability of the equipment, while ensuring the hygiene and safety of food during the frying process.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
