Description

Technical Field

[0001] This utility model belongs to the field of peanut oil processing technology, specifically relating to a peanut oil processing cooling device. Background Technology

[0002] In the large-scale processing of peanut oil, the temperature of pressed or refined peanut oil is typically as high as 60-85℃. If it is directly filtered, bottled, or stored, the high temperature will cause the oil to oxidize and become rancid, destroying nutrients such as unsaturated fatty acids and vitamin E. It may also cause problems such as packaging material deformation and microbial growth. Therefore, rapidly cooling high-temperature peanut oil to below 30℃ is a key process to ensure product quality and extend shelf life. The performance of the cooling device directly determines the efficiency of peanut oil processing and the quality of the finished product.

[0003] Currently, the mainstream peanut oil cooling technologies in the industry all have significant shortcomings in practical applications, making it difficult to meet the production requirements of high efficiency, uniformity, and ease of maintenance. For example, some small and medium-sized processing plants still use the natural static cooling mode to inject high-temperature peanut oil into open or semi-open containers and dissipate heat naturally through air convection; however, this method has extremely low cooling efficiency, easily causes process backlog, and has poor temperature uniformity, with a temperature difference layer easily forming between a low-temperature upper layer and a high-temperature lower layer in the peanut oil inside the container;

[0004] For example, most processing plants use tank-type cooling devices, which have one or more cooling pipes installed on the outside or inside of a closed cooling tank, and heat exchange is achieved through the circulation of coolant in the pipes. However, in this type of cooling pipe design, the cooling pipes are mostly single-loop or partially arranged, and there are blind spots on the outer or inner wall of the cooling tank that are not covered. This results in a temperature difference of 5-8°C in the peanut oil inside the tank. In some areas, the oil is not cooled completely and still needs secondary cooling. Moreover, disassembly and maintenance are cumbersome. The cooling pipes and the cooling tank are mostly welded or integrally formed structures. If the inner wall of the cooling pipes is blocked by oil and scale due to long-term use, the entire device needs to be disassembled for cleaning, which is time-consuming and seriously affects the continuity of production.

[0005] In summary, current peanut oil cooling technologies generally suffer from two main problems: first, it is difficult to balance efficiency and uniformity, as efficient cooling often results in excessive temperature differences, while uniform cooling requires sacrificing efficiency; second, disassembly and maintenance costs are high, and the integrated structure leads to time-consuming cleaning and repairs, affecting the production line's uptime. Therefore, based on these shortcomings, the applicant proposes a better technical solution to address these technical issues.

[0032] Example

[0033] like Figures 1 to 6 As shown, a peanut oil processing cooling device includes a cooling tank 1, a cooling mechanism 2, and a stirring mechanism 3. The cooling tank 1 has an inlet 11 and an outlet 12 at its upper and lower ends, respectively, and an annular boss 13 is recessed around its periphery. The cooling mechanism 2 includes a cylindrical frame 21, multiple cooling pipes 22, and multiple U-shaped connecting pipes 23. The cylindrical frame 21 is inserted into the annular boss 13, and both its upper and lower ends are provided with ring plates 211. Multiple limiting slots 2111 are opened on the ring plates 211, and the multiple cooling pipes 22 are respectively locked in the multiple limiting slots 2111 and connected to the limiting slots 2111 through a limiting component 4. The annular boss 13 is the core mounting position of the cooling mechanism 2, used to insert and position the cylindrical frame 21, to prevent the cooling mechanism 2 from shifting during operation, and to ensure the fit between the coolant circulation path and the cooling tank, which directly affects the uniformity of cooling.

[0034] One of the cooling pipes 22 is provided with a liquid inlet 221, and a U-shaped connecting pipe 23 is connected between the inlet and the last cooling pipe 22 in a clockwise direction from this point. The lower end of the last cooling pipe 22 is provided with a liquid outlet 222. The stirring mechanism 3 is located inside the cooling tank 1.

[0035] This utility model has multiple cooling pipes 22 connected in series by U-shaped connecting pipes 23 to form a ring-shaped layout, which fully covers the outer wall of the cooling tank 1. Combined with the stirring mechanism 3, it allows the peanut oil to flow fully, solving the problems of local cooling blind spots and large temperature differences between the inside and outside of traditional devices. The cooling rate is significantly improved, and the oxidation and rancidity of the oil caused by local high temperature are effectively avoided.

[0036] In this embodiment, please refer to Figure 2 and Figure 5 The limiting component 4 includes connecting pieces 41 and fastening bolts 42 located on opposite sides of the cooling pipe 22. The connecting pieces 41 are mounted on the ring piece 211 and connected to it by the fastening bolts 42. In this example, the connecting pieces 41 and fastening bolts 42 are used to connect the cooling pipe 22 to the ring piece 211, which facilitates subsequent disassembly and assembly.

[0037] In this embodiment, a limiting component 2 5 is provided between the upper end of the cylindrical frame 21 and the cooling tank 1. The limiting component 2 5 includes an L-shaped plate 51 and a fastening bolt 2 52. The L-shaped plate 51 abuts against the upper end of the cylindrical frame 21 and is connected to the cooling tank 1 by the fastening bolt 2 52. Specifically, an elongated hole can be opened in the L-shaped plate 51, and a threaded groove that mates with the fastening bolt 2 52 is opened on the cooling tank 1 to facilitate control of the position of the L-shaped plate 51. Then, the fastening bolt 2 52 is used to fix the L-shaped plate 51 on the cooling tank 1 by mate with the threaded groove.

[0038] In this invention, the flow of coolant during the cooling process will generate vibration. The invention employs a double-limiting mechanism, consisting of limit component 4 and limit component 5, to prevent displacement and ensure the stability of the structure.

[0039] In this embodiment, both ends of the U-shaped connecting pipe 23 are rotatably connected to the connecting components 6, and the connecting components 6 are threadedly connected to the cooling pipe 22. The two ends of the U-shaped connecting pipe 23 are connected to the cooling pipe 22 through the connecting components 6, so as to connect multiple cooling pipes 22 in series to form a complete circulation channel from the liquid inlet 221 to the initial cooling pipe 22, pipe 2, pipe 3, ... the last cooling pipe 22 to the liquid outlet 222, so as to realize the cooling treatment of peanut oil in the cooling tank 1 by using the cooling pipes 22.

[0040] For details, please refer to 3 and Figure 6 The connecting component 6 includes a hollow rotating part 61 and a fastening nut 62. The rotating part 61 is rotatably connected to the end of the U-shaped connecting pipe 23. The outer surface of the rotating part 61 is provided with external threads, and it is threadedly connected to the cooling pipe 22 through the external threads. The fastening nut 62 is engaged with the external threads. In specific operation, the rotating part 61 first connects the U-shaped connecting pipe 23 and the cooling pipe 22 through the threaded connection with the cooling pipe 22. Then, the fastening nut 62 is tightened to secure the connection between the U-shaped connecting pipe 23 and the cooling pipe 22, thereby preventing coolant leakage. This structure allows for quick assembly and disassembly of the U-shaped connecting pipe 23, making the operation simple and convenient.

[0041] In this embodiment, please refer to Figure 1 and Figure 4 The bottom of the cooling pipe 22 is also provided with a drain port 7; the drain port 7 is designed to facilitate the complete drainage of residual coolant and avoid the growth of microorganisms caused by long-term idleness.

[0042] The stirring mechanism 3 and the cooling mechanism 2 work together to make the peanut oil in the cooling tank 1 tumble and flow through mechanical agitation, avoiding local overheating caused by differences in heat conduction, and ensuring that the temperature of the peanut oil in the whole tank drops evenly, thereby improving the cooling quality. In this example, the stirring mechanism 3 adopts a conventional motor and stirring blade configuration, which will not be described in detail here.

[0043] The working principle of this utility model:

[0044] This utility model provides a peanut oil processing cooling device. In specific use, high-temperature peanut oil is injected from the upper feed port 11 of the cooling tank 1. After the liquid level in the tank reaches the preset height, the feed port 11 is closed.

[0045] Coolant (such as cold water or low-temperature ethylene glycol solution) is injected from the inlet 221 of the first cooling pipe 22 and flows sequentially through the series of cooling pipes 22 (guided by U-shaped connecting pipe 23). During the flow, it exchanges heat with the cooling tank 1 through the pipe wall, absorbing the heat of the peanut oil in the tank, and finally is discharged from the outlet 222 of the last cooling pipe 22 (it can be recycled and re-injected).

[0046] Simultaneously start the stirring mechanism 3 in the cooling tank 1 to keep the peanut oil flowing in the tank, avoid local temperature differences due to differences in heat conduction, and ensure that all peanut oil is in uniform contact with the tank wall and fully exchanges heat with the cooling pipes;

[0047] When the peanut oil temperature drops to the preset value (usually below 30℃), stop the cooling cycle and stirring, open the discharge port 12 at the bottom of the cooling tank 1, and discharge the cooled peanut oil to complete one cooling process.

[0048] This utility model adopts a detachable structure to ensure stable connection of each component, while facilitating subsequent cleaning and maintenance, and realizing efficient, hygienic and continuous peanut oil cooling processing.

[0049] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
