Description

Technical Field

[0001] This invention relates to the field of peanut butter production technology, and in particular to a raw material crushing device for peanut butter production. Background Technology

[0002] In peanut butter production, a common raw material grinding device is a highly efficient grinding machine specifically designed for processing roasted peanuts. It typically combines grinding, shearing, and impact to break the peanut kernels into a fine paste, laying the foundation for subsequent mixing and emulsification. The core components of this device include high-speed rotating blades or hammers, fixed liners, and a precise temperature control system designed to ensure that the peanuts are not overheated during grinding, thus preserving their flavor and quality. However, current peanut butter production faces a significant challenge: even after roasting and preliminary processing, some of the thin peanut skin still remains on the surface of the peanut kernels. This skin not only affects the texture and appearance of the final product, potentially giving it a slightly grainy texture or dull color, but it can also introduce a slight bitterness, reducing the overall smoothness and flavor purity of the peanut butter. This problem arises because traditional grinding devices often focus on efficient particle refinement but fail to fully integrate the skin removal function, resulting in skin fragments being ground along with the peanut kernels during the grinding process, making complete separation difficult. More notably, current technologies typically cannot simultaneously complete the peeling and cooling of roasted peanuts within the same process. Peanuts, after high-temperature roasting, carry a significant amount of heat. Directly introducing them into the grinding process not only exacerbates skin adhesion, making peeling more difficult, but also risks oil oxidation and flavor deterioration due to sustained high temperatures. Ideally, the production process should involve rapid cooling immediately after roasting to stabilize the texture and reduce skin residue. However, current equipment designs often treat peeling, cooling, and grinding as independent processes, requiring additional equipment or steps. For example, peeling might rely on separate friction or air-based sorting equipment, while cooling requires dedicated cooling conveyors or air circulation systems. This not only increases the complexity and energy consumption of the production line but can also lead to reduced efficiency and quality fluctuations due to poor coordination between processes. Therefore, while grinding devices excel in refining raw materials, there is still room for improvement in the overall process optimization to achieve integrated and efficient processing of peeling, cooling, and grinding.

[0003] Chinese Patent Publication No. CN217042748U discloses a raw material crushing device for peanut butter production, including a crushing box. A hopper is installed on the top of the crushing box, and a flow-limiting component is installed inside the hopper. Two crushing rollers are rotatably installed inside the crushing box, and the two rollers mesh. A discharge port is provided at the bottom of the crushing box. Inclined guide troughs are installed on both sides of the crushing box, with one end extending into the crushing box and located below the ends of the crushing rollers. Conveying pipes are fixed to both sides of the crushing box, and a driving assembly is installed inside the conveying pipes. The driving assembly includes a conveying screw rotatably installed inside the conveying pipe and a motor installed at the bottom of the conveying pipe. Therefore, the raw material crushing device for peanut butter production described in the above patent document achieves material crushing, recovers any material missed during crushing, and re-crushes it, thereby effectively preventing some material from leaking out and improving the uniformity of crushing.

[0004] While the device described in the aforementioned patent document can crush peanuts during use, it cannot cool down roasted peanuts in actual use, and peanut skins will still remain on the surface of the peanut kernels, thus affecting the taste of the peanut butter produced later.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figure 1 and Figure 2 As shown, a raw material crushing device for peanut butter production includes a base 1. Four support rods 2 arranged in a ring array are fixedly connected to the upper end of the base 1. A ring frame 3 is fixedly connected to the upper end of the four support rods 2. An outer cylinder 4 is fixedly connected to the inner surface of the ring frame 3. An air inlet pipe 5 is fixedly connected to the upper right side of the outer surface of the outer cylinder 4. The air inlet pipe 5 communicates with the inner cavity of the outer cylinder 4. An installation rod 6 is fixedly connected to the right end of the air inlet pipe 5. An air intake fan 7 is electrically connected to the outer surface of the installation rod 6. A storage component 8 is fixedly installed on the left side of the outer surface of the outer cylinder 4. A grinding component 9 is fixedly installed at the lower end of the outer cylinder 4. A sorting component 10 is fixedly installed in the middle of the inner surface of the outer cylinder 4. A crushing component 11 is fixedly installed on the upper part of the inner surface of the outer cylinder 4.

[0021] During use, roasted peanuts are poured into the crushing component 11, which initially crushes them. While the crushing component 11 is crushing the peanuts, the outer skin of the peanut kernels is blown into the storage component 8 by the air generated by the air intake fan 7, which is electrically connected to the outer surface of the mounting rod 6, as the air in the intake fan 7 rotates. The peanut kernels fall onto the surface of the sorting component 10. The airflow generated inside the sorting component 10 continues to blow upwards. Since the mass of the peanut kernels is greater than the mass of the outer skin, the outer skin is always blown upwards. The peanut kernels fall downwards into the inner cavity of the grinding component 9. When the inner cavity of the sorting component 10 stops receiving air, it closes automatically to prevent the remaining peanut skins from falling into the grinding component 9. This prevents the outer skins from falling downwards with the peanut kernels. Finally, the peanut kernels fall into the grinding component 9 for grinding, thus grinding them into a paste.

[0022] The electrical connection between the intake fan 7 and the mounting rod 6 mentioned above is a conventional connection method in the prior art. In this solution, it is only necessary to control the intake fan 7 to draw the gas outside the intake pipe 5 into the outer cylinder 4 when it rotates. The specific installation method, circuit connection method and control method are all conventional designs and can be adjusted according to actual production needs. Therefore, this solution will not be described in detail.

[0023] Example 2, as Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment, the storage component 8 includes an L-shaped tube 81 fixedly connected to the upper left side of the outer surface of the outer cylinder 4. The L-shaped tube 81 communicates with the inner cavity of the outer cylinder 4. A semi-arc plate 82 is fixedly connected to the right edge of the horizontal part of the inner surface of the L-shaped tube 81. A plurality of filter holes 83 are opened on the outer surface of the semi-arc plate 82. A threaded sleeve 84 is threadedly connected to the lower side of the vertical part of the inner surface of the L-shaped tube 81.

[0024] Furthermore, the grinding assembly 9 includes a conical cylinder 91 fixedly connected to the lower end of the outer cylinder 4. A support frame 92 is fixedly connected to the middle left side and the middle right side of the inner surface of the conical cylinder 91. A housing 93 is fixedly connected to the middle upper end of the support frame 92. A motor 94 is fixedly connected to the bottom wall of the housing 93. Four arc-shaped support plates 96 are fixedly connected in a ring array to the lower part of the inner surface of the outer cylinder 4. A grinding disc 97 is slidably connected to the lower part of the inner arc surface of the four arc-shaped support plates 96 on the side that is close to each other. Grinding disc 2 98 is fixedly connected to the upper part of the inner arc surface of the two sides of the two sides. A material discharge port is opened on the rear side of the middle part of the upper end of grinding disc 2 98, which extends to its lower end. An arc-shaped tube 99 is fixedly connected to the upper part of the inner surface of the material discharge port. A drive rod 90 is rotatably connected to the middle part of the upper end of grinding disc 2 98. The lower end of the drive rod 90 passes through the lower end of grinding disc 1 97 and is fixedly connected to the upper end of motor 94 through a coupling. The outer surface of the drive rod 90 is fixedly connected to the inner surface of grinding disc 1 97, and the upper end of the drive rod 90 passes through the outer surface of arc-shaped tube 99.

[0025] Furthermore, the sorting component 10 includes a conical box 101 fixedly connected to the middle of the inner surface of the outer cylinder 4. The outer arc surface of the conical box 101 has eight mounting holes arranged in an annular array. Each of the eight mounting holes has an air inlet pipe 102 fixedly connected to its inner surface. Each of the eight air inlet pipes 102 has an air intake mechanism 103 fixedly installed on its inner surface. A blocking component 104 is fixedly installed at the upper end of the conical box 101.

[0026] Furthermore, the blocking assembly 104 includes a receiving plate 1041 fixedly connected to the upper end of the conical box 101. The upper end of the receiving plate 1041 has a plurality of rectangular discharge holes 1042 arranged in an array. A rotating plate 1043 is rotatably connected to the lower left side of the inner surface of each of the rectangular discharge holes 1042. An abutment plate 1044 is fixedly connected to the lower right side of the inner surface of each of the rectangular discharge holes 1042. The abutment plate 1044 on the same side is located below the rotating plate 1043 on the same side. A counterweight bar 1045 is fixedly connected to the lower right end of each of the rotating plates 1043. Four inner arc plates 1046 are fixedly connected to the upper part of the outer surface of the drive rod 90. The four inner arc plates 1046 are located on the upper side of the receiving plate 1041.

[0027] Furthermore, the crushing assembly 11 includes a disc 111 fixedly connected to the upper part of the inner surface of the outer cylinder 4. Several drop grooves 112 are arranged in a row on the upper end of the disc 111. Four mounting blocks are fixedly connected to the upper part of the outer surface of the drive rod 90. Crushing rollers 113 are rotatably connected to the ends of the four mounting blocks that are far apart from each other. Several crushing balls 114 are fixedly connected to the outer surfaces of the four crushing rollers 113.

[0028] Furthermore, a semi-circular inclined plate 115 is fixedly connected to the upper left side of the inner surface of the outer cylinder 4. The semi-circular inclined plate 115 is located on the upper side of the four crushing rollers 113. A semi-circular plate 116 is fixedly connected to the right end of the semi-circular inclined plate 115. Several feed ports 117 are linearly arrayed on the upper end of the semi-circular plate 116. A baffle 118 is fixedly connected to the upper right side of the outer cylinder 4. A partition 119 is fixedly connected to the lower left side of the baffle 118.

[0029] Furthermore, the lower end of the conical box 101 is fixedly connected to the upper end of the bow-shaped tube 99, and the upper end of the drive rod 90 passes through the receiving plate 1041 and is rotatably connected to the lower end of the semi-circular inclined plate 115.

[0030] Furthermore, the outer surfaces of the eight air inlet ducts 102 all penetrate the inner surface of the outer cylinder 4 and extend to the outside.

[0031] During use, roasted peanuts are poured from the upper opening of the outer cylinder 4 onto the upper end of the semicircular inclined plate 115. Since the upper end of the semicircular inclined plate 115 is inclined, the peanuts will roll down to the position of the semicircular plate 116 and then fall from the upper end of the semicircular plate 116 through several feeding ports 117 to the upper end of the disc 111. During this process, the motor 94 is started, and the output end of the motor 94 drives the drive rod 90 fixedly connected to it to rotate through the coupling. When the drive rod 90 rotates, it can drive the four mounting blocks fixedly connected to it to rotate. The ends of the four mounting blocks that are far apart from each other are rotatably connected to the crushing roller 113, and several crushing balls 114 are fixedly connected to the outer surface of the four crushing rollers 113. Therefore, when the four mounting blocks rotate with the drive rod 90, several crushing balls 114 can roll on the upper end of the disc 111, thereby driving the crushing roller 113 on the same side to rotate, thus achieving the effect of preliminary crushing of peanuts. When peanuts are crushed, their outer skin separates from the peanut kernel. At this time, when the intake fan 7 draws external gas into the outer cylinder 4, it can blow some of the peanut skin off the surface of the peanut kernel. Then, under its own weight, the peanut kernel falls down from several drop grooves 112 to the surface of the receiving plate 1041. The horizontal part of the inner surface of the L-shaped tube 81 is fixedly connected to a semi-arc plate 82. Several filter holes 83 opened on the outer surface of the semi-arc plate 82 can only allow gas and crushed peanut skin to pass through. Therefore, the peanut kernel falls to the surface of the receiving plate 1041 through the drop grooves 112, while the peanut skin enters the inner cavity of the L-shaped tube 81 through the filter holes 83. When the peanut kernels fall onto the upper side of the receiving plate 1041, the eight air intake mechanisms 103 are activated, causing them to simultaneously blow external air into the inner cavity of the conical box 101. After the air collides, it surges upwards, and this upward flow of air blows the rotating plate 1043 up, preventing it from obstructing the lower side of the rectangular discharge hole 1042. The peanut kernels that fall onto the surface of the receiving plate 1041 may still have a small amount of outer skin fragments. The upward-flowing gas will blow the remaining peanut skins upward, and when the drive rod 90 rotates, it can simultaneously drive the four inner arc plates 1046 fixedly connected to its outer surface to rotate. The ends of the four inner arc plates 1046 that are far apart from each other are all set with arc surfaces. Therefore, when the inner arc plates 1046 rotate, they can not only move the peanut kernels on the upper side of the receiving plate 1041, but also move the blown-up outer skins to the connection between the L-shaped tube 81 and the outer cylinder 4, so that the peanut skins enter the inner cavity of the L-shaped tube 81. If the air intake mechanism 103 stops injecting gas into the inner cavity of the conical box 101, several rotating plates 1043 will fall downward under the influence of the counterweight bar 1045 on the same side, and then rest against the upper side of the abutment plate 1044 on the same side, blocking the lower side of the rectangular discharge hole 1042 on the same side. Furthermore, the blown gas can also cool down the roasted peanuts, and the crushed peanuts will fall from the lower end of the conical box 101 into the inner cavity of the bow-shaped tube 99. A part of the drive rod 90 is located in the inner cavity of the bow-shaped tube 99, but it only passes through the bow-shaped tube 99 and its outer diameter is smaller than the inner diameter of the bow-shaped tube 99. Therefore, the peanuts can fall through the bow-shaped tube 99 into the material discharge port on the upper side of the grinding disc 2 98. When the peanut kernels fall into the feeding port of the second grinding disc 98, the second grinding disc 98 is fixedly connected to the four arc-shaped support plates 96, and its inner surface is rotatably connected to the drive rod 90. The first grinding disc 97 is slidably connected to the four arc-shaped support plates 96. Therefore, when the drive rod 90 rotates, it can simultaneously drive the first grinding disc 97, which is fixedly connected to its outer surface, to rotate. Then, the first grinding disc 97 and the second grinding disc 98 continuously feed the peanut kernels into the feeding port through the arc-shaped tube 99 for grinding. The ground paste then flows from the periphery of the first grinding disc 97 into the conical cylinder 91. The outer shell 93 encloses the motor 94, so the paste will not stick to the surface of the motor 94, thus avoiding affecting its normal operation. The resulting peanut butter will flow out through the opening at the bottom of the cone 91. Simply place an item in the opening at the bottom of the cone 91 to receive it. The peanut skin fragments blown into the inner cavity of the L-shaped tube 81 are caught by the burlap sack tied to the outer surface of the threaded sleeve 84, so as to facilitate the reuse of the peanut skins. The burlap sack tied to the outer surface of the threaded sleeve 84 has good air permeability, so the gas can leak out from the surface of the burlap sack, while the peanut skin fragments are stored inside the burlap sack. When it is necessary to remove the peanut skin fragments, simply rotate the threaded sleeve 84 to remove the threaded sleeve 84 and the burlap sack together, and then turn the threaded sleeve 84 from its original upward opening downward to pour out the peanut skin fragments from the burlap sack.

[0032] The burlap sack mentioned above is a conventional setup in the prior art. In this solution, it is only necessary to ensure that it is tied to the outer surface of the threaded sleeve 84 and has good air permeability. The specific binding method and materials can be adjusted according to actual usage requirements, so this solution will not elaborate on them further.

[0033] The air intake mechanism 103 mentioned above is a conventional setting in the prior art. In this solution, it consists of a rod for installation and an air intake fan. In this solution, it is only necessary to ensure that after installation in the air intake pipe 102, external air is drawn from the outside of the air intake pipe 102 into the inner cavity of the conical box 101. Its specific installation method, circuit connection method and control method are all conventional designs in the prior art and can be adjusted according to actual production needs. Therefore, this solution will not elaborate on them in detail.

[0034] In the aforementioned grinding process between millstone 1 (97) and millstone 2 (98), when peanut kernels are fed into the gap between millstone 1 (97) and millstone 2 (98) through the hole in millstone 2 (98), they first experience immense pressure from the weight of millstone 2 (98) itself. This pressure initially crushes and breaks down the originally intact and somewhat brittle peanut kernels into smaller particles. The contact surfaces between millstone 1 (97) and millstone 2 (98) have uneven grinding teeth. The presence of these teeth means that the contact surfaces between millstone 1 (97) and millstone 2 (98) are not completely flat. When millstone 1 (97) rotates relative to millstone 2 (98), these shifting grinding teeth act like countless tiny, moving "scrapers" and "washboards," applying strong shearing forces to the already partially crushed peanut particles. Shearing force is a force with a shifted direction, which can effectively tear and cut the particles further, making them even finer.

[0035] At the same time, there is a huge friction between the peanut kernels themselves and the surfaces of grinding disc 1 97 and grinding disc 2 98. This friction not only generates heat but also participates in the crushing process. The heat generated is very important because it slightly "excites" the rich oil inside the peanut. This oil begins to seep out slightly, making the originally dry and loose peanut powder become moist and sticky. Thus, in the enclosed space of grinding disc 197 and grinding disc 298, the hard solid particles become smaller and smaller under the repeated and synergistic action of pressure, shear force and friction. At the same time, the released grease acts as a natural "lubricant" and "adhesive", which wraps around those extremely small solid particles and fuses them together to form a stable, semi-fluid gel-like system. Finally, as the repeatedly ground material is pushed out from the edge of the millstone 97, its original physical structure is completely destroyed, and the oils and solids are finely blended together to form peanut butter.

[0036] It should be noted that the specific installation method, circuit connection method, and control method of the motor 94 used in this invention are all conventional designs, and will not be described in detail here.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
