[0001] This invention relates to the field of edible oil processing, and in particular to a method for processing peanut oil. Background Technology

[0002] Peanut oil processing refers to the methods of extracting crude peanut oil from peanut seeds or refining crude peanut oil into finished oil. Different processing techniques are used depending on the oil quality requirements, mainly divided into pressed peanut oil production processes, solvent-extracted peanut oil production processes, and refined peanut oil production processes. Among these, pressed peanut oil is obtained by pressing. However, during the pressing process, the peanut skin can affect the crushing effect, thus impacting the oil quality. Summary of the Invention

[0003] The purpose of this invention is to provide a peanut oil processing method that uses a drying device to completely remove the peanut skin.

[0029] like Figure 2 As shown:

[0030] A method for processing peanut oil, the method comprising the following steps:

[0031] Step 1: Wash the peanuts thoroughly and let them dry;

[0032] Step 2: Place the peanuts into the hopper 301 of the drying device;

[0033] Step 3: Separate the peanut shells and transfer the peanut kernels to the filter barrel 201 of the drying device;

[0034] Step 4: Introduce hot air at 50-60 degrees Celsius into the drying device.

[0035] like Figure 4-6 As shown:

[0036] The system includes a frame 101, a universal joint 103 fixed to the frame 101, a central shaft 106 fixed to the other end of the frame 101, a drying cylinder 102 fixed to the central shaft 106, a filter barrel 201 rotatably connected to the central shaft 106, multiple friction rods 202 machined on the inner wall of the filter barrel 201, a peeling frame 107 fixed to the central shaft 106, a slider 109 slidably connected inside the peeling frame 107, a peeling roller 108 rotatably connected inside the slider 109, a second electric push rod fixed between the slider 109 and the peeling frame 107, and a first rotary motor installed between the central shaft 106 and the filter barrel 201.

[0037] After shelling, the peanuts are placed in the filter barrel 201. Then, the first rotary motor is driven to rotate, causing the filter barrel 201 to rotate on the central shaft 106. The friction rod 202 inside the filter barrel 201 stirs the peanuts, allowing the hot air to come into more thorough contact with the peanuts and ensuring uniform heating. After heating for a period of time, the peanut skins become dry, which drives the second electric push rod to push the slider 109 downward. The slider 109 then moves the peeling roller 108 downward together, bringing it into contact with the peanuts. The peeling roller 108 and the filter barrel 201 work together to rub the peanuts, removing the peanut skins. Hot air is then blown into the filter barrel 201 through the filter holes, blowing out the broken peanut skins and obtaining clean peanuts, thus improving the quality of the peanut oil.

[0038] After the peanut kernels have been dried for a period of time, the second electric push rod is driven to continue to lower the peeling roller 108, thereby further reducing the distance between the peeling roller 108 and the filter barrel 201. As the filter barrel 201 stirs the peanuts, it carries the peanuts under the peeling roller 108, which then squeezes the peanuts and crushes them, thereby improving the drying efficiency.

[0039] like Figure 6 and Figure 7 As shown:

[0040] The corrugated plate 206 is fixedly connected to the filter barrel 201, the cleaning plate 204 is slidably connected inside the drying cylinder 102, and two cleaning springs 205 are fixedly connected between the cleaning plate 204 and the drying cylinder 102. The corrugated plate 206 contacts the tail of the cleaning plate 204, and multiple cleaning needles are machined at the lower end of the cleaning plate 204.

[0041] During the peanut crushing process, the crushed peanut pieces may become embedded in the filter holes of the filter barrel 201 due to compression, thus affecting the entry of hot air into the filter barrel 201 and adversely affecting the drying process. Therefore, a corrugated plate 206 is fixedly attached to the tail of the filter barrel 201, and a cleaning plate 204 is slidably connected inside the drying cylinder 102. The tail of the cleaning plate 204 is processed into a cylinder, so that the cylindrical part contacts the corrugated surface of the corrugated plate 206. Two cleaning springs 205 press the cleaning plate 204 tightly against the surface of the corrugated plate 206. When the corrugated plate 206 rotates with the filter barrel 201, the corrugated plate 206 drives the cleaning plate 204 to move up and down inside the drying cylinder 102. Multiple cleaning needles are fixedly attached to the lower end of the cleaning plate 204. When the cleaning plate 204 moves downward, the cleaning needles are inserted into the filter holes of the filter barrel 201 to clean the filter barrel 201, thereby ensuring the unobstructed flow of the filter holes and thus ensuring the drying effect.

[0042] like Figure 6 As shown:

[0043] Two baffles 203 are symmetrically fixed inside the drying cylinder 102, and the air inlet 104 is fixed to the tail of the drying cylinder 102.

[0044] Dry hot air is introduced through the air inlet 104 between the drying cylinder 102 and the filter barrel 201, and blown onto the peanuts through the filter holes of the filter barrel 201, thereby drying the peanuts. Two baffles 203 are fixed to the inner wall of the drying cylinder 102, and the lower end of the baffles 203 is inclined towards the filter barrel 201, thereby blocking the hot air and concentrating the hot air mainly in the lower half of the drying cylinder 102. This allows the drying cylinder 102 to heat up quickly and has better heat preservation capabilities, thereby improving the drying efficiency of the peanuts. After the peanut skins are peeled off, some of them will enter the drying cylinder 102 through the filter holes. The baffles 203 collect the peanut skins for easy cleaning later.

[0045] like Figure 3 and Figure 4 As shown:

[0046] An annular groove is machined on the outer surface of the drying barrel. A first electric push rod 105 is fixedly connected to the frame 101. A fixing ring 110 is rotatably connected to the movable end of the first electric push rod 105. The fixing ring 110 is installed in the annular groove.

[0047] When peanuts are added to the filter barrel 201, the first electric push rod 105 is driven to rise, thereby pushing the fixing ring 110 to move upward. The fixing ring 110 pushes the front end of the drying cylinder 102 upward. The rear end of the drying cylinder 102 is fixed to the universal joint 103 through the central shaft 106, so the drying cylinder 102 rotates around the universal joint 103, thereby raising the drying cylinder 102 to collect the peanuts. After adding peanuts, the first electric push rod 105 is driven to fall back, and the drying cylinder 102 is fixed in a slightly upward angle to prevent peanuts from escaping from the opening of the filter barrel 201 during processing. After the peanuts are dried, the first electric push rod 105 is driven to fall, causing the drying cylinder 102 to tilt downward, thereby pouring out the processed peanuts.

[0048] like Figure 8 and Figure 9 As shown:

[0049] The hopper 301 is fixedly connected to the frame 101, the two shell-breaking plates 302 are slidably connected inside the hopper 301, the compression spring 303 is fixedly connected between the two shell-breaking plates 302, and a vibration device is provided between the two shell-breaking plates 302.

[0050] Whole peanuts are poured into hopper 301, and the vibration device is driven. During the rotation of the vibration device, the two shell-breaking plates 302 are repeatedly opened, while the compression spring 303 repeatedly pulls the two shell-breaking plates 302 back. As the peanuts pass between the two shell-breaking plates 302, they are impacted by the two shell-breaking plates 302, thus breaking them and extracting the peanut kernels.

[0051] like Figure 9 As shown:

[0052] The oscillation device includes a dial 304, two slide rods 305 slidably connected inside the dial 304, and two rollers 306 rotatably connected inside the two slide rods 305 respectively.

[0053] Move the two slide rods 305 in opposite directions to allow them to slide within the dial wheel 304. Adjust the position of the two slide rods 305 until they are in the appropriate position. Then, fix the two slide rods 305 with screws. Next, drive the dial wheel 304 to rotate, causing the rollers 306 at the front of the two slide rods 305 to alternately contact the two shell-breaking plates 302, thereby repeatedly opening the two shell-breaking plates 302 to crack the peanuts. To crack peanuts of different sizes, adjust the length of the two slide rods 305 extending out of the dial wheel 304, thereby changing the opening degree of the dial wheel 304 in opening the two shell-breaking plates 302.

[0054] like Figure 8 and Figure 10 As shown:

[0055] The screen 401 is slidably connected below the hopper 301. The screen 401 includes an upper screen plate and a lower conveying plate. The rotating shaft 402 is rotatably connected inside the upper screen plate. Multiple rubber fan blades 403 are fixedly connected to the rotating shaft 402.

[0056] After being shelled, peanuts fall through hopper 301 onto the upper screen plate of screen 401. Screen 401 is then vibrated to separate the peanut kernels from their shells, allowing the kernels to pass through the upper screen 401 and fall onto the lower conveyor plate. However, some peanut kernels are too tightly embedded in their shells and are difficult to separate. This causes a third rotary motor to drive a rotating shaft 402 to rotate within the upper screen plate. As the shaft 402 rotates, rubber blades 403 mounted on it repeatedly beat the peanuts, further separating the kernels from their shells and ensuring that no peanuts are wasted.

[0057] like Figure 8-11 As shown:

[0058] The connecting rod 404 is rotatably connected to the lower conveyor plate, the slide column is fixedly connected to the other end of the connecting rod 404, the slide column is slidably connected to the rotating ring 405, the slide column and the nut 406 are threadedly connected, the drive shaft 307 is fixedly connected between the rotating ring 405 and the dial wheel 304, the drive shaft 307 is rotatably connected to the frame 101, and a second rotary motor is provided between the drive shaft 307 and the frame 101.

[0059] The second rotary motor is driven to rotate, which in turn drives the transmission shaft 307 to rotate. The transmission shaft 307 simultaneously drives the rotating ring 405 and the dial wheel 304 fixed at both ends to rotate. When the dial wheel 304 rotates, it cracks the peanut shells. When the rotating ring 405 rotates, it drives the sliding column located at the eccentric position of the rotating ring 405 to move, thereby pulling the connecting rod 404 to reciprocate. The other end of the connecting rod 404 is rotatably connected to the screen 401, so the connecting rod 404 drives the screen 401 to reciprocate under the hopper 301, thereby vibrating the screen 401 and making the peanut kernels separate from the shells more thoroughly.
