Description

Technical Field

[0001] This utility model relates to the field of peanut oil pressing, specifically a rapid cooling device for roasting peanut oil using traditional pressing methods. Background Technology

[0002] In traditional peanut oil pressing, roasting is a crucial step. It not only enhances the flavor of the peanuts but also activates enzyme activity through appropriate heat treatment, improving oil extraction efficiency. However, roasted peanuts need to be rapidly cooled to a suitable temperature for subsequent pressing. Traditional cooling methods typically rely on natural cooling or simple air-cooling devices. Natural cooling is time-consuming, and simple air-cooling devices struggle to achieve uniform and effective cooling, leading to extended production cycles and failing to meet the needs of modern, high-efficiency production. Furthermore, inconsistent and insufficient cooling rates can cause material accumulation, affecting the cooling effect and resulting in localized overheating or uneven cooling. This impacts the quality of the peanuts and the consistency and stability of the oil extracted during subsequent pressing. Moreover, traditional cooling processes often require manual intervention to adjust material distribution and monitor the cooling progress. This not only increases labor costs but also easily leads to batch-to-batch quality fluctuations due to operational differences. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content

[0026] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the peanut oil traditional pressing and rapid cooling device after roasting according to this utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] See Figures 1-3 This embodiment of the peanut oil traditional pressing and rapid cooling device after roasting enables smooth flow and even spreading of roasted peanuts, and utilizes airflow to accelerate the material cooling process, shortening the cooling time and improving the efficiency of the entire production process. Simultaneously, it allows for circulating heat dissipation of the peanuts, further enhancing product consistency and quality stability. Furthermore, it achieves a high degree of automation in equipment operation, reducing the impact of human factors on the production process. In this embodiment, it mainly includes a support 1, on which a feeding hopper 2 is fixedly mounted. The feeding hopper 2 is a rectangular structure with an open top. A partition 6 is fixedly mounted inside the feeding hopper 2, and the partition 6 is inclined and positioned in the middle of the feeding hopper 2, with a gap between the lowest end of the partition 6 and the inner wall of the feeding hopper 2. Roasted peanuts are poured into the feeding hopper 2, and the peanuts fall from above the partition 6 into the feeding hopper 2 below the partition 6 through the gap between the partition 6 and the feeding hopper 2.

[0029] A four-cornered pyramid 7 is fixedly installed at the bottom of the feeding hopper 2. The top and bottom of the pyramid 7 are both open, and the bottom of the pyramid 7 tapers towards the center. An interference cloth 8, which is a cylindrical structure with open top and bottom, is fixedly installed at the bottom of the pyramid 7. Peanuts below the partition 6 fall from the bottom of the feeding hopper 2 into the pyramid 7, where they are guided and buffered, and then fall downwards from the bottom of the pyramid 7. At this time, the interference cloth 8 buffers the peanuts, preventing them from splashing.

[0030] To ensure the peanuts are evenly spread and cooled. See also Figure 1 and Figure 2 In this embodiment, an inclined spreading plate 3 is fixedly installed on the support 1 below the hopper 2. The spreading plate 3 is a trapezoidal structure with its short side on top and its long side on the bottom, and its short side is located below the interference cloth 8. Peanuts falling from the interference cloth 8 land on the inclined spreading plate 3. Side plates 9 are fixedly installed at both ends of the spreading plate 3 to prevent peanuts on the spreading plate 3 from falling off from the sides. Multiple spreading strips 10 are horizontally fixedly installed on the spreading plate 3. The spreading strips 10 are triangular structures. The hypotenuse of the spreading strips 10 is located directly above, and the smallest angle of the spreading strips 10 faces the short side of the spreading plate 3. The peanuts fall downwards through the inclined direction of the spreading plate 3. During this process, the spreading strips 10 and the trapezoidal spreading plate 3 work together to spread the peanuts evenly.

[0031] A ventilation duct 11 is fixedly mounted on the support 1 at the opposite bottom end of the spreading plate 3. A fan wheel 12 is coaxially rotatable inside the ventilation duct 11, and a first motor 13 is fixedly mounted at the end of the ventilation duct 11 to drive the fan wheel 12. An air outlet 14 facing the spreading strip 10 is opened on the side of the ventilation duct 11, and a filter cloth is provided at the air outlet 14 to prevent peanuts from falling into the ventilation duct 11. An air inlet 15 is opened at the top of the ventilation duct 11. When the peanuts move on the spreading plate 3, the first motor 13 is activated, driving the fan wheel 12 to rotate, thereby drawing air in through the air inlet 15 and expelling it through the air outlet 14, blowing it onto the spreading plate 3. At this time, the air carries away the heat from the peanuts on the spreading plate 3, cooling them. During this process, the triangular structure of the spreading plate 3 prevents the peanuts from flowing back upwards and disperses the airflow, ensuring that the peanuts are blown by air from all directions.

[0032] To achieve circulating heat dissipation, in this embodiment, see... Figure 1 and Figure 3A heat dissipation box 4 is fixedly mounted on the support 1 at the bottom of the spreading plate 3. The heat dissipation box 4 is a rectangular structure with an open top. The bottom plate of the spreading plate 3 is sloped, and its highest point is located directly below the bottom of the spreading plate 3. The lowest point of the heat dissipation box 4 has a discharge port 16. Peanuts falling from the spreading plate 3 fall into the heat dissipation box 4 and flow through the slope of its bottom plate to the discharge port 16, achieving natural cooling in the process.

[0033] A preparation box 5, connected to the heat dissipation box 4, is fixedly mounted on the support 1 above the side of the feeding hopper 2. The side of the preparation box 5 is connected to the top of the feeding hopper 2. The preparation box 5 is a rectangular structure with an open top, and its bottom plate is sloped with its lowest point facing the feeding hopper 2. A lifting cylinder 17 is vertically fixed inside the preparation box 5, and a spiral auger 18 is coaxially rotatably mounted inside the lifting cylinder 17. A second motor 19 for driving the spiral auger 18 is fixedly mounted at the top of the lifting cylinder 17. The bottom of the lifting cylinder 17 is connected to the outlet of the discharge port 16, and a discharge port 20 is opened on the side of the top of the lifting cylinder 17. By controlling the second motor 19 to work, the spiral auger 18 is driven to rotate, thereby lifting the peanuts that fall into the lifting cylinder 17 from the discharge port 16 upwards and dropping them into the preparation box 5 from the discharge port 20.

[0034] The preparatory box 5 has a discharge port 21 on its bottom side wall facing the feeding hopper 2, and the feeding hopper 2 has a receiving port 22 on its top side facing the preparatory box 5. A connecting bridge 23 is fixedly installed between the discharge port 21 and the receiving port 22. The connecting bridge 23 is a U-shaped structure with its opening facing upwards, and the highest end of the partition 6 is located below the receiving port 22. An electric push rod 24 is vertically fixedly installed on the side wall of the preparatory box 5, and a baffle 25 that can block the discharge port 21 is fixedly installed at the telescopic end of the electric push rod 24. By controlling the operation of the electric push rod 24, the baffle 25 is driven to rise and fall, thereby controlling the opening size of the discharge port 21. At this time, the peanuts in the preparatory box 5 fall from the discharge port 21 along the connecting plate into the receiving port 22, thus entering the interior of the feeding hopper 2. The partition 6 separates the cooled peanuts from the uncooled peanuts. This achieves cyclic cooling of the peanuts, improving product consistency and quality stability.

[0035] The method of using the peanut oil traditional pressing and rapid cooling device after roasting is as follows: First, the roasted peanuts are poured into the hopper 2. The peanuts fall from above the partition 6 into the hopper 2 below the partition 6 through the gap between the partition 6 and the hopper 2. The peanuts below the partition 6 fall from the bottom of the hopper 2 into the four-cornered pyramid 7, where they are guided and buffered, and then fall downwards from the bottom of the pyramid 7. At this time, the peanuts are buffered by the interference cloth 8 to prevent them from splashing. The peanuts falling from the interference cloth 8 land on the inclined spreading plate 3. The peanuts fall downwards along the inclined direction of the spreading plate 3. During this process, the peanuts are evenly spread by the cooperation of the spreading strip 10 and the trapezoidal spreading plate 3.

[0036] As the peanuts move on the spreading plate 3, the first motor 13 is activated, driving the fan wheel 12 to rotate. This draws air in through the air inlet 15 and exhausts it through the air outlet 14, blowing it onto the spreading plate 3. The air carries away the heat from the peanuts on the spreading plate 3, cooling them. During this process, the triangular structure of the spreading plate 3 prevents the peanuts from flowing back upwards and disperses the airflow, ensuring the peanuts are exposed to airflow from all directions.

[0037] Peanuts falling from the spreading plate 3 enter the cooling box 4 and flow along the inclined surface of its bottom plate to the discharge port 16, achieving natural cooling during this process. The second motor 19 is controlled to operate, driving the auger 18 to rotate, thereby lifting the peanuts that have fallen from the discharge port 16 into the lifting cylinder 17 and dropping them from the discharge port 20 into the preparation box 5. The electric actuator 24 is controlled to operate, driving the baffle 25 to rise and fall, thereby controlling the opening size of the discharge port 21. At this time, the peanuts in the preparation box 5 fall from the discharge port 21 along the connecting plate into the receiving port 22, thus entering the interior of the discharge hopper 2. The partition 6 separates the cooled peanuts from the uncooled peanuts. This achieves cyclic cooling of the peanuts, improving product consistency and quality stability.
