Description

Technical Field

[0001] This utility model relates to the field of oil pressing, and in particular to a peanut oil pressing device. Background Technology

[0002] As a nutritious and easily digestible edible oil, the pressing process of peanut oil is crucial to the quality and production efficiency of the oil.

[0003] Peanut oil exists in spherical or granular form within the cells, surrounded by a closed membrane. During pressing, the cell wall structure of intact peanut kernels is not sufficiently disrupted, leading to obstructed oil release channels. This necessitates applying extremely high pressure during pressing, significantly increasing energy consumption and resulting in a higher residual oil content. Furthermore, uncrushed peanut kernels are prone to uneven pressure during pressing, generating localized high temperatures that cause protein denaturation and oil oxidation, affecting the oil's color and nutrient retention.

[0004] Therefore, there is a need for peanut oil pressing devices that can crush peanuts in advance. Utility Model Content

[0005] In view of this, the present invention aims to provide a peanut oil pressing device to solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] This utility model proposes a peanut oil pressing device, including a crushing cylinder with an internal cavity, a top cover fixedly installed on the top of the crushing cylinder, a rotating roller rotatably connected to the bottom surface of the top cover and located inside the crushing cylinder, a motor fixedly installed on the crushing cylinder, a feeding hopper opened on the top of the crushing cylinder, a collecting chamber communicating with the bottom of the crushing cylinder, an oil pressing chamber fixedly connected to one end of the collecting chamber, a pressure plate slidably installed in the collecting chamber and the oil pressing chamber, and a cylinder fixedly installed at the other end of the collecting chamber. The end of the cylinder is fixedly connected to the pressure plate, the end of the motor is fixedly connected to the top of the rotating roller, and the side wall of the oil pressing chamber is provided with multiple oil outlet holes at intervals.

[0008] The radius of the rotating roller gradually increases from top to bottom, and the pressure plate conforms to the inner contour of the collecting chamber and the pressing chamber.

[0009] Furthermore, a heating cover is fixedly provided on the outer wall of the crushing cylinder, and multiple air outlets are spaced apart on the top cover.

[0010] Furthermore, the rotating roller is fixedly provided with spiral patterns in a spiral shape.

[0011] Furthermore, the rotating roller is provided with a plurality of protrusions at intervals.

[0012] Furthermore, the end of the oil pressing chamber away from the collecting chamber is open and has a bottom plate, which is fixedly connected to the collecting chamber by a fixing part.

[0013] Furthermore, the fixing part is L-shaped and symmetrically arranged on both sides of the bottom plate, with its end fixedly connected to the outer wall of the oil pressing chamber, and the bottom plate abutting against the fixing part.

[0014] Furthermore, a sliding plate is fixedly provided on the side of the pressing plate away from the oil pressing chamber, the end of the sliding plate extends to the outside of the collecting chamber, and the top surface of the pressing plate is in close contact with the top surface of the collecting chamber.

[0015] Furthermore, a base is fixedly provided on the outer wall of the collection cavity.

[0016] Furthermore, a protective shell is fixedly provided on the top of the crushing cylinder, the motor is fixedly installed inside the protective shell, a protective cover is fixedly provided on the outer wall of the collecting chamber, and the cylinder is fixedly installed inside the protective cover.

[0017] Compared with the prior art, this utility model has the following advantages:

After crushing, the cell wall structure of the peanut kernels is fully disrupted, and the oil release channels are widened. During the pressing process, high-efficiency oil extraction can be achieved without applying extremely high pressure, thus reducing energy consumption. At the same time, the crushing process also reduces the residual oil rate after pressing, improving oil extraction efficiency. Attached Figure Description

[0028] The following will refer to the appendix. Figures 1 to 3 The present invention will be described in detail with reference to the embodiments.

[0029] Overall, this utility model relates to a peanut oil pressing device, including a crushing cylinder 1 with an internal cavity, a top cover 101 fixedly installed on the top of the crushing cylinder 1, a rotating roller 4 rotatably connected to the bottom surface of the top cover 101 and located inside the crushing cylinder 1, a motor 201 fixedly installed on the crushing cylinder 1, a feed hopper 3 opened on the top of the crushing cylinder 1, a collection chamber 5 connected to the bottom of the crushing cylinder 1, an oil pressing chamber 6 fixedly connected to one end of the collection chamber 5, a pressure plate 7 slidably installed in the collection chamber 5 and the oil pressing chamber 6, a cylinder 702 fixedly installed at the other end of the collection chamber 5, the end of the cylinder 702 being fixedly connected to the pressure plate 7, the end of the motor 201 being fixedly connected to the top of the rotating roller 4, and a plurality of oil outlet holes 601 spaced apart on the side wall of the oil pressing chamber 6;

[0030] The radius of the rotating roller 4 gradually increases from top to bottom, and the pressure plate 7 conforms to the inner contour of the collecting chamber 5 and the oil pressing chamber 6.

[0031] In this invention, the crushing cylinder 1 and the rotating roller 4 work together to achieve efficient crushing of peanut kernels. The rotating roller 4 is designed with a gradually increasing radius from top to bottom, allowing the peanut kernels to gradually adapt to the shape changes when squeezed by the rotating roller 4, thus achieving a uniform crushing effect. This not only improves the pre-treatment efficiency of peanut kernels before pressing but also provides favorable conditions for the subsequent pressing process. After crushing, the cell wall structure of the peanut kernels is fully destroyed, and the oil release channels are widened. During the pressing process, high-efficiency oil extraction can be achieved without applying extremely high pressure, thereby reducing energy consumption. At the same time, the crushing process also reduces the residual oil rate after pressing and improves the oil extraction efficiency.

[0032] This invention integrates automated components such as a motor 201 and a cylinder 702, achieving fully automated operation from crushing to pressing. This not only reduces labor intensity but also improves production efficiency.

[0033] In practice, peanut kernels to be pressed are fed into the crushing cylinder 1 through the feed hopper 3. At this time, the motor 201 starts, driving the rotating roller 4 to rotate. As the rotating roller 4 rotates, the peanut kernels are subjected to gradually increasing compressive force within the crushing cylinder 1, thus achieving uniform crushing. The crushed peanut kernel fragments fall into the collecting chamber 5. When the peanut kernel fragments in the collecting chamber 5 reach a certain amount, the cylinder 702 starts working, pushing the pressure plate 7 to slide along the inner contour of the collecting chamber 5 and the oil pressing chamber 6. At this time, the pressure plate 7 compacts the peanut kernel fragments in the collecting chamber 5, preparing for the subsequent pressing process. Under the action of the pressure plate 7, the peanut kernel fragments are further compressed, and the oil flows out from the oil outlet 601 on the side wall of the oil pressing chamber 6. During the pressing process, the thrust of the cylinder 702 can be adjusted as needed to control the pressing pressure and oil output speed. After pressing, the extracted peanut oil is collected for filtration and refining. Simultaneously, the residue after pressing is manually discharged from the device.

[0034] It should be noted that, in order to reduce the operating pressure of the motor 201 driving the rotating roller 4, in this embodiment, the rotating roller 4 is hollowed out, which reduces the overall weight and thus reduces the operating pressure of the motor 201.

[0035] To improve the oil extraction efficiency, in this embodiment, a heating hood 9 is fixedly installed on the outer wall of the crushing cylinder 1, and multiple air vents 102 are spaced apart on the top cover 101. The heating hood 9 can preheat or maintain a certain temperature in the crushing cylinder 1, which helps to soften the peanut kernels, making them easier to crush under the action of the rotating roller 4. In addition, proper heating of the peanut kernels can also promote the fluidity and release rate of the oil. During the pressing process, the heated peanut kernel fragments are easier to compact, and the oil channels are easier to open, thereby increasing the oil yield.

[0036] During the crushing process, the vent 102 on the top cover 101 continuously discharges hot and humid air from the crushing cylinder 1. Operators can observe the air discharge and adjust the temperature of the heating hood 9 and the speed of the motor 201 as needed to maintain optimal crushing performance.

[0037] The heating cover 9 is preferably an existing surround heating cover 9, which contains heating elements such as resistance wires or heating tubes. When these heating elements are energized, they generate heat.

[0038] like Figure 2 and Figure 3 As shown, based on the above settings, in this embodiment, the rotating roller 4 is fixedly provided with a spiral pattern 401 in a spiral shape, and a plurality of protrusions 402 are fixedly provided on the rotating roller 4 at intervals.

[0039] The rotation of the spiral 401 propels the material forward within the crushing cylinder 1, achieving continuous crushing and pressing. It also ensures uniform material distribution within the crushing cylinder 1, improving crushing efficiency. Furthermore, the rotation of the spiral 401 not only propels the material forward but also exerts shearing and compressive forces on it through its shape, thereby enhancing the crushing effect.

[0040] The protrusion 402 increases the contact area and friction between the rotating roller 4 and the material, thereby enhancing the crushing and pressing effect. This helps to more thoroughly crush and press the material, increasing oil yield and pressing efficiency.

[0041] It should be noted that the end of the oil pressing chamber 6 away from the collecting chamber 5 is open and is provided with a bottom plate 602. The bottom plate 602 is fixedly connected to the collecting chamber 5 through a fixing part 603.

[0042] In this embodiment, when the cylinder 702 operates, it pushes the peanut kernels from the collecting chamber 5 into the oil pressing chamber 6 for oil pressing. After the oil pressing is completed, peanut kernel residue will be left on the inner side wall of the bottom plate 602. By removing the bottom plate 602, it is convenient for workers to clean the oil pressing residue.

[0043] Based on the above configuration, the fixing part 603 is L-shaped and symmetrically arranged on both sides of the bottom plate 602. Its end is fixedly connected to the outer wall of the oil pressing chamber 6, and the bottom plate 602 abuts against the fixing part 603.

[0044] In practice, the bottom plate 602 can be slid upward to remove it, exposing the residue in the pressing chamber for easy collection. It should be noted that the bottom plate 602 and the fixing part 603 are limited by friction.

[0045] like Figure 1 and Figure 2 As shown, a sliding plate 701 is fixedly provided on the side of the pressing plate 7 away from the oil pressing chamber 6. The end of the sliding plate 701 extends to the outside of the collecting chamber 5, and the top surface of the pressing plate 7 is in close contact with the inner top surface of the collecting chamber 5.

[0046] In actual operation, the pressing and crushing of peanut kernels are carried out simultaneously. In order to prevent peanut kernels from falling into the collection chamber 5 during pressing and affecting the normal operation of the device, in this embodiment, a sliding plate 701 is fixedly provided on the side of the pressing plate 7 away from the oil pressing chamber 6. The end of the sliding plate 701 extends to the outside of the collection chamber 5, and the top surface of the pressing plate 7 is in close contact with the inner top surface of the collection chamber 5.

[0047] In practice, when cylinder 702 drives pressure plate 7 to press, cylinder 702 pushes the peanut kernels towards the oil pressing chamber 6. Simultaneously, it drives sliding plate 701 to slide directly below rotating roller 4, blocking the connection between crushing cylinder 1 and collecting chamber 5, thus receiving the peanuts inside crushing cylinder 1 and allowing crushing and pressing to occur simultaneously. After pressing, cylinder 702 drives pressure plate 7 to reset, and sliding plate 701 releases its blocking function, allowing the crushed peanut kernels to fall into collecting chamber 5. It should be noted that the top surface of sliding plate 701 is flush with the top surface of pressure plate 7.

[0048] like Figure 1 and Figure 2 As shown, a protective shell 2 is fixedly installed on the top of the crushing cylinder 1, the motor 201 is fixedly installed inside the protective shell 2, a protective cover 703 is fixedly installed on the outer wall of the collecting chamber 5, and the cylinder 702 is fixedly installed inside the protective cover 703.

[0049] In this embodiment, the protective shell 2 protects the motor 201, preventing external factors from interfering with its normal operation. In actual use, the protective shell 2 has heat dissipation holes and wiring holes to facilitate heat dissipation of the motor 201 and access to external power. Similarly, the protective cover is used to protect the cylinder 702, and it also has heat dissipation holes and wiring holes to facilitate wiring and heat dissipation of the cylinder 702.

[0050] In addition, a base 8 is fixedly installed on the outer wall of the collection chamber 5. The base 8 can support the device and facilitate the collection of residue and finished oil.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
