Description

Technical Field

[0001] This utility model relates to the field of industrial processing equipment for food, and specifically to a feeding structure for a horizontal frying equipment. 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 mainly includes two types: vertical and horizontal. Vertical frying equipment typically occupies less space and has relatively limited processing capacity, making it suitable only for home or small-scale production environments. In contrast, horizontal frying equipment is known for its larger processing capacity and continuous production capability, making it more suitable for large-scale industrial production. However, traditional horizontal frying equipment has many shortcomings in material supply, such as the inability to separate oil and food feeding, uneven feeding, and susceptibility to blockages. During material feeding, hot oil splattering can pose safety risks. Furthermore, material supply issues can lead to oil level fluctuations, affecting supply efficiency and frying quality, thus reducing overall production efficiency and product quality. These problems not only reduce frying efficiency but may also negatively impact product quality.

[0004] Therefore, designing a feeding structure that can effectively solve the above problems is of great significance for improving the overall performance and food processing efficiency of horizontal frying equipment. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a feeding structure for a horizontal frying equipment. The structure is assembled on the front side of the frying chamber of the horizontal frying equipment, which can realize continuous feeding of food in the frying chamber, so as to solve the problems existing in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: A feeding structure for a horizontal frying equipment includes a closed outer shell, an oil volume cavity formed inside the closed outer shell, and a food feeding port on one side of the top surface of the closed outer shell. The enclosed outer shell also includes an inner shell within the oil volume chamber. This inner shell has a mesh structure, and a horizontally positioned inner cavity is separated on the opposite side of the food feeding port within the oil volume chamber. This inner cavity has a circular cross-section and is connected to the frying chamber of the horizontal frying equipment at its rear. The lower part of the food feeding port is provided with a feeding channel that communicates with the inner cavity. The feeding channel is provided with a horizontally placed comb-shaped baffle plate on the lower part of the side near the inner cavity, and a feeding cylinder is provided on the opposite side of the comb-shaped baffle plate. The feeding cylinder is externally driven by a motor. Multiple radially arranged comb-shaped blades are formed on the cylinder body of the feeding cylinder, and the comb teeth on these comb-shaped blades are staggered with the comb teeth of the comb-shaped baffle plate.

[0007] As a further limitation, the inner wall of the oil volume chamber, the inner shell, and the spiral blades of the screw conveyor are all made of 316 stainless steel or coated with Teflon.

[0008] As a further limitation, the enclosed outer shell has openings formed on both sides of the corresponding structural cavity; the front opening of the enclosed outer shell is assembled and connected to the end cover plate through a flange with a sealing element, and the rear opening is assembled and connected to the frying chamber of the horizontal frying equipment through a flange with a sealing element.

[0009] As a further limitation, a screw conveyor is also provided in the inner cavity of the structure. The screw conveyor is coaxially arranged with the inner cavity of the structure, and the output length of the screw conveyor and the size of the screw blades provided on the screw conveyor are matched with the length and inner diameter of the inner cavity of the structure. The screw conveyor is driven by an external motor, and its feeding direction is consistent with the flow direction of the food. The spiral blades are evenly distributed with sieve holes.

[0010] As a further limitation, a guiding slope is provided on the feeding channel, and the bottom of the guiding slope corresponds to the surface of the comb-shaped baffle plate, so as to facilitate the guidance of the food fed into the feeding port and its sliding onto the surface of the comb-shaped baffle plate.

[0011] As a further limitation, the comb teeth on the comb-shaped deflector have a bent portion, the bending direction of which is opposite to the rotation direction of the feeding cylinder. During the rotation of the feeding cylinder, the bent portion of the comb teeth interacts with the comb teeth of the comb-shaped baffle, so that the food is subjected to a continuously changing pushing force between the comb-shaped deflector and the comb-shaped baffle, thereby achieving uniform dispersion and feeding of the food.

[0012] As a further limitation, both the comb-shaped paddle and the comb teeth on the comb-shaped baffle are made of elastic material; and the comb teeth on the comb baffle have the material strength to support the weight of the food.

[0013] As a further limitation, the closed outer shell has an oil filling port formed on the outer wall of the shell on the same side as the corresponding food feeding port, which is connected to the oil volume cavity; The oil filling port is equipped with a quick-connect oil pipe connector, and an inward baffle is provided on the inner side of the sealed outer shell corresponding to the position of the quick-connect oil pipe connector to prevent oil from splashing during pressurized injection.

[0014] Beneficial effects: The feeding structure of this utility model for horizontal frying equipment has the advantages of simple structure, easy assembly and maintenance. Through the setting of a closed outer shell and inner shell, in conjunction with the feeding channel, comb-shaped baffle and feeding cylinder, it realizes the uniform dispersion and stable conveying of food before frying, effectively improving the production efficiency and product quality of the frying equipment, and effectively avoiding the problems of material supply in traditional horizontal frying equipment. This technology can be widely integrated into various types of horizontal frying equipment, significantly improving its feeding efficiency and frying operation quality. Attached Figure Description

[0018] 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.

[0019] See Figure 1 , Figure 2 A preferred embodiment of a feeding structure for a horizontal frying equipment is shown in this embodiment, which illustrates the assembly form of the feeding structure on the horizontal frying equipment. The corresponding horizontal frying equipment includes a frame 10, which is a split steel structure support. The front support is used to support the feeding section 12 and the frying section 9 of the equipment, while the rear support is used to support the discharging section 8 of the equipment.

[0020] In this embodiment, the feeding section 12, frying section 9, and discharging section 8 are independently formed, and are connected between the feeding section 12 and the frying section 9, and between the frying section 9 and the discharging section 8, by flange connections 4 with seals to ensure that the oil in the frying chamber does not leak. After assembly, the feeding section 12, the frying section 9, and the discharging section 8 form a continuous volumetric cavity. During the frying operation, the feeding section 12 is used to feed the food, which is then fed into the frying section 9 through the feeding structure. After frying, the food enters the discharging section 8. Due to the characteristics of puffed fried food, the food floats on the surface of the oil in the discharging section 8, and is continuously discharged from the discharging port 7 by a scraper conveyor 6 positioned at the oil surface. As the food moves on the surface of the scraper conveyor 6, the air blowing device 5 blows off excess oil droplets from the surface of the food, reducing the oil content of the food and improving the healthiness of the product.

[0021] In this embodiment, the feeding structure serves as the main body of the feeding section 12, used to continuously feed the food to be fried into the frying section. The structural style of its main body is as follows: Figure 2 As shown, it includes a closed outer shell 15, both sides of which are open. The front open surface is fitted with the end face base 14 through the flange connection part 4, and the rear open surface is fitted with the frying section 9 through the flange connection part 4.

[0022] The inner side of the enclosed outer shell 15 has an oil volume chamber 23, which is designed to hold oil for frying and to exchange heat with the frying section 9 to preheat the food entering the feeding section 12.

[0023] An inner shell 16 is provided inside the oil volume cavity 23. The inner shell 16 has a mesh structure and surrounds a structural cavity inside the oil volume cavity 23. The structural cavity is located on the left side of the oil volume cavity 23, has a circular cross-section, is placed horizontally in the oil volume cavity 23, and matches the front open surface and the rear open surface at both ends, respectively.

[0024] Enclosed outer shell 15 Figure 1 A food inlet 3 is provided on the top right side, and a guide slope is formed at the lower edge of the food inlet 3. The lower part of the food inlet 3 corresponds to the feeding channel, and the end of the feeding channel is connected to the inner cavity of the structure enclosed by the inner shell 16 on the side. A horizontal comb-shaped baffle 22 is provided on the lower left side of the feeding channel, and a horizontal feeding cylinder 21 is provided on the lower right side of the feeding channel. The feeding cylinder 21 is connected to the feeding cylinder drive motor 11, and driven by the feeding cylinder drive motor 11, the feeding cylinder 21 can move as follows. Figure 2In the indicated state, when rotated clockwise, the cylinder of the feeding cylinder 21 has multiple radially arranged paddles formed on its body. The paddles are comb-shaped paddles 20, and the comb-shaped paddles 20 have comb teeth with counterclockwise bends formed at intervals. At the same time, the comb teeth on these comb-shaped paddles 20 are misaligned with the comb teeth of the comb-shaped baffle plate 22.

[0025] Both the comb-shaped pick 20 and the comb-shaped baffle 22 are made of elastic material, and the comb-shaped baffle 22 has sufficient material strength to support and disperse the food temporarily stored on its surface for frying.

[0026] When food is fed into the food inlet 3, it is first guided by the guide ramp to the comb-shaped baffle 22 within the feeding channel. Then, by rotating the feeding cylinder 21 clockwise, the comb-shaped baffle 20 sequentially pushes the food fed into the inlet 3 into the structural cavity, effectively preventing uneven frying caused by food accumulation. During this process, the food is subjected to continuously varying pushing forces between the comb-shaped baffle 20 and the comb-shaped baffle 22, ensuring uniform dispersion and stable delivery. Furthermore, the unidirectional rotation of the feeding cylinder 21, combined with the reverse blocking effect of the comb-shaped baffle 22, effectively prevents food materials that have already entered the structural cavity from returning to the feeding channel of the feeding device, ensuring the continuity and stability of the frying operation.

[0027] The internal cavity of the structure is connected to the frying chamber of the frying section 9 in the horizontal frying equipment on the rear side of the feeding structure. In order to enable the food in the internal cavity to continuously and smoothly enter the frying chamber for frying, the end face base 14, in addition to serving as an end face cover to close the front opening of the closed outer shell 15, can also serve as a mounting base for the secondary shaft drive motor 1 and the main shaft drive motor 2. The secondary shaft drive motor 1 and the main shaft drive motor 2 are respectively mounted on the end face base 14, and their output shafts are connected to the main shaft 17 and the secondary shaft respectively through corresponding transmission mechanisms. The main shaft 17 is provided with a main spiral blade 18, and the secondary shaft is provided with a secondary spiral blade (the secondary shaft and the secondary spiral blade are located in the frying chamber of the frying section 9 and are not shown). The length and spiral size of the main spiral blade 18 match the length and inner diameter of the internal cavity of the structure. The secondary spiral blade is an extension of the main spiral blade 18 and is located in the frying chamber of the frying section 9. Its length and spiral size match the length and inner diameter of the frying chamber. The main spiral blade 18 and the secondary spiral blade push in the same direction as the flow direction of the food, that is, push the food from the inner cavity of the feeding structure in the feeding section 12 to the frying cavity of the frying section 9, and then push it from the frying cavity of the frying section 9 to the discharge section 8.

[0028] The screw conveyor not only improves the efficiency of food delivery but also ensures that food enters the frying chamber at a predetermined speed and quantity. The coaxial arrangement and matching design of the screw conveyor allow it to stably transport food from one end of the internal cavity to the other during operation without damaging the food.

[0029] In this embodiment, both the main spiral blade 18 and the auxiliary spiral blade are equipped with sieve holes. These sieve holes allow the oil in the oil volume chamber 23 and the frying chamber to communicate with each other, promoting the flow and exchange of oil between them. Furthermore, the sieve hole design also helps to stably transport food on the spiral conveyor, effectively preventing slippage or blockage during transport. The oil in the frying chamber communicates and flows through the sieve holes, forming localized eddies, which helps to form a crispy outer layer on the food surface, thus significantly improving the texture of the food.

[0030] In addition, in this embodiment, the outer sidewall of the enclosed outer shell 15 is also provided with an oil filling port 13 on the outer sidewall corresponding to the food feeding port 3. The oil filling port 13 is connected to the oil volume cavity 23 on the inner side. During the frying operation, hot oil is injected into the oil volume cavity 23 through the oil filling port 13 and permeates into the inner cavity of the structure through the mesh structure of the inner shell 16 to replenish the amount of oil consumed normally. In order to improve the convenience and practicality of the oil filling port 13, a quick-connect oil pipe connector is provided on the oil filling port 13 to facilitate the quick connection and injection of oil, while the inner baffle 19 effectively prevents the oil from splashing during pressurized injection, ensuring the cleanliness and safety of the working environment.

[0031] In different embodiments, the inner wall of the oil volume chamber 23, the inner shell, the spiral blades of the spiral conveyor, and the surfaces that the high-temperature oil can contact are all coated with a Teflon coating to enhance the corrosion resistance and durability of the equipment, while ensuring the hygiene and safety of food during the frying process.

[0032] 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.
