[0034] See Figures 1-3 The adjustable-pressure peanut oil pressing device of this embodiment allows for convenient feeding of peanut raw materials through its horizontal setting, and facilitates the removal of the pressed peanut cake. It forms multiple independent pressing chambers 3, enabling a single power source to process multiple batches of raw materials simultaneously, increasing the output and efficiency of a single operation. Furthermore, it allows for precise pressure control, adjusting the pressing force according to different types of peanuts or oil content to ensure optimal oil yield and product quality. In this embodiment, it mainly includes a horizontally placed pressing cylinder 1, which is a semi-circular structure with an open top.

Side plates 8 are fixedly installed at both ends of the pressing cylinder 1, and the side plates 8, together with the cover plates 2 and the pressing cylinder 1, form a closed cylindrical structure. Multiple pressing chambers 3 are formed between the cover plates 2 and the pressing cylinder 1.

[0035] The pressing cylinder 1 has fixing plates 9 on both sides of its top, and the cover plate 2 has limiting plates 10 fixedly installed on both sides of its bottom. The fixing plates 9 are hinged to the corresponding limiting plates 10. The fixing plates 9 have limiting holes 11 that penetrate the limiting plate 10 on the hinged side, and the limiting plate 10 on the other side has a U-shaped groove 12 corresponding to the limiting hole 11. Bolts 13 are installed inside the limiting holes 11, and the bolts 13 that match the U-shaped groove 12 are fixedly installed to the corresponding limiting holes 11. During peanut pressing, the bolts 13 are tightened to fix the positions of the fixing plates 9 and limiting plates 10, thereby fixing the relative positions of the cover plate 2 and the pressing cylinder 1. After pressing, the bolts 13 are unscrewed, and then the cover plate 2 is lifted from the hinged position through the U-shaped groove 12, and the peanut cake is then removed from the pressing chamber 3.

[0036] For ease of material loading and unloading. See also Figure 1 and Figure 2 In this embodiment, a discharge port 14 is provided at the top of the cover plate 2, and a discharge hopper 15 is fixedly provided on the cover plate 2 on the side of the discharge port 14. A detachable top plate 16 is provided inside the discharge hopper 15, and a handle 17 is fixedly provided on the top of the top plate 16. The top plate 16 has an arc-shaped structure and together with the cover plate 2, the pressing cylinder 1, and the side plate 8, forms a cylindrical shape. During discharge, the top plate 16 is lifted upward by the handle 17, and then the peanut raw material is poured from the discharge hopper 15 into the pressing cylinder 1. Through holes 18 are provided on both sides of the opposite end of the discharge hopper 15, and an insert plate 19 is fixedly provided on the outside of the discharge hopper 15. A limiting post 20 that can penetrate the corresponding through hole 18 is fixedly provided on the insert plate 19. After the peanut raw material is poured in, the top plate 16 is placed back on the discharge hopper 15. At this time, the limiting post 20 of the insert plate 19 is inserted into the through hole 18 to fix the position of the top plate 16 and seal the inside of the pressing chamber 3.

[0037] To achieve the pressing of peanuts. In this embodiment, see... Figures 1-3 The pressing cylinder 1 is internally equipped with a pressing mechanism 4 adapted to the pressing chamber 3. The pressing mechanism 4 includes a baffle 41 fixedly disposed on the side of the pressing chamber 3, the baffle 41 being coaxially disposed with the pressing cylinder 1. A horizontally slidable extrusion plate 42 is disposed inside the pressing chamber 3 on the opposite side of the baffle 41, the extrusion plate 42 being coaxially disposed with the baffle 41. Sliding grooves 43 are provided on both sides of the pressing cylinder 1 of the pressing chamber 3, and sliding blocks 44 that can slide within the sliding grooves 43 are fixedly disposed on both sides of the extrusion plate 42.

[0038] A lead screw 45 is coaxially rotatably mounted in the middle of the side plate 8, passing through the middle of the baffle 41 and the extrusion plate 42. The lead screw 45 is rotatably mounted with the baffle 41 and threadedly connected to the extrusion plate 42. A bidirectional motor 46 with a reducer is fixedly mounted on the side of the bracket 6 to drive the lead screw 45 to rotate.

[0039] The bidirectional motor 46 is controlled to operate, and the power, after passing through the reducer, drives the lead screw 45 to rotate, thereby driving the extrusion plate 42 to move towards the baffle 41, thus pressing the peanut raw material. During this process, the slider 44 slides within the chute 43 for guidance. The internal pressure is monitored in real time by the pressure sensor 47 and the pressure gauge 48. This allows for precise control of the position of the extrusion plate 42, adjusting the pressing force according to different types of peanuts or oil content to ensure optimal oil yield and product quality.

[0040] For filtering and collecting peanut oil. See details. Figure 1 and Figure 3 The pressing cylinder 1 has an oil outlet 5 at its bottom, and an arc-shaped grid plate 21 is fixedly installed on the oil outlet 5. The arc-shaped grid plate 21 is coaxially arranged with the pressing cylinder 1, and a filter cloth 22 is fixedly installed on the top of the arc-shaped grid plate 21. The filter cloth 22 is supported by the arc-shaped grid plate 21. The support 6 has a collection groove 7 corresponding to the oil outlet 5. One side of the collection groove 7 is located directly below the oil outlet 5, and the bottom end of the collection groove 7 below the oil outlet 5 is an inclined surface 23. The inclined surface 23 facilitates the subsequent transfer of oil. During the pressing process of peanut raw materials, the pressed oil is filtered by the filter plate and falls into the collection groove 7 through the arc-shaped grid plate 21.

[0041] The method of using the adjustable pressure peanut oil pressing device of this utility model is as follows: First, tighten the bolts 13 to fix the positions of the fixing plate 9 and the limiting plate 10, thereby fixing the relative positions of the cover plate 2 and the pressing cylinder 1. When feeding, use the handle 17 to lift the top plate 16 upwards, and then pour the peanut raw material from the feeding hopper 15 into the pressing cylinder 1. After the peanut raw material is poured in, put the top plate 16 back on the feeding hopper 15. At this time, insert the limiting post 20 of the insert plate 19 into the through hole 18 to fix the position of the top plate 16 and seal the inside of the pressing chamber 3.

[0042] The bidirectional motor 46 is controlled to operate, and the power drives the lead screw 45 to rotate through the reducer, thereby driving the extrusion plate 42 to move towards the baffle 41, thus pressing the peanut raw material. During this process, the slider 44 slides within the chute 43 for guidance. The internal pressure is monitored in real time by the pressure sensor 47 and the pressure gauge 48. This allows for precise control of the position of the extrusion plate 42, adjusting the pressing force according to different types of peanuts or oil content to ensure optimal oil yield and product quality. During the pressing of the peanut raw material, the pressed oil is filtered through the filter plate and falls into the collection tank 7 through the arc-shaped grid 21. After pressing, the bolt 13 is unscrewed, and then the cover plate 2 is lifted from the hinged position through the U-shaped groove 12, and the peanut cake is then removed from the pressing chamber 3.
