[0022] See Figures 1-5 The convenient oil pressing unit provided in this application includes: a machine box 1, a feeding hopper 112, a frying pan 113, a pot lid handle 115, a connecting pipe 114, a receiving plate 2, a discharge hopper 21, a motor cooling fan 124, a crushing zone 24, rollers 121, an oil pressing zone 122, a receiving frame 123, a guide plate 124, a nitrogen storage tank 31, a fresh oil storage tank 32, a filter press 33, a fixing protrusion 332, a connecting bolt 331, a pressure gauge 333, a lifting rod 311, a pressing screen 312, a filter cloth 313, a supporting screen plate 314, a support frame 315, a conical bottom 316, and a support leg 322; The casing 1 includes an upper casing and a lower casing. The upper casing houses a feed hopper 112 and a frying pan 113. The feed hopper 112 is positioned above the frying pan 113 and connected to it via a connecting pipe 114. A lid is fitted over the frying pan 113, with a handle 115 on it. The lid has a symmetrical two-half structure, covering the frying pan 113. When closed, the lid has a through hole in its center, into which the connecting pipe 114 is accommodated. The lower casing includes a crushing zone 24 and an oil pressing zone 122. The crushing zone 24 is positioned above the oil pressing zone 122. The crushing device is located within the crushing zone 24; the oil pressing device is housed within the oil pressing zone 122. A slag outlet is provided on one side of the box in the oil pressing area 122 to discharge the oil residue formed after oil pressing; a guide plate 124 is provided below the slag outlet. One end of the guide plate 124 is connected to the lower edge of the slag outlet, and the other end extends outward at an angle. The extended end is set into the receiving frame 123 to realize the directional guidance, feeding and collection of oil residue and prevent oil residue from leaking out.
[0023] A frame is installed at the bottom of the upper box, which is positioned above the feed inlet of the lower box. The feed inlet of the lower box houses a receiving plate 2, which is connected to the lower box at opposite ends. Multiple feeding hoppers 21 are symmetrically arranged at the other two ends. The bottom opening of each feeding hopper 21 has a size of 25-30mm x 30-40mm. This size improves the feeding rate and increases processing efficiency. The discharge end of the feeding hopper 21 is aligned with the feed inlet of the crushing device within the crushing zone 24, thus allowing the roasted raw materials from the upper box to be fed into the lower crushing device.
[0024] The receiving plate 2 is equipped with inclined plates 212 at both ends of the feeding hopper 21. The angle between the inclined plates 212 and the receiving plate 2 is 10~18°. By setting the inclined plates, the falling movement rate of the material entering the inclined plate area can be accelerated, thereby increasing the feeding speed. A rotating push rod 211 is set on the receiving plate 2 between the two inclined plates 212. The transmission components and drive motor of the rotating push rod 211 are housed in the lower housing. The specific structure is set according to the existing integrated oil press structure, and will not be described in detail here.
[0025] The oil pressing device in the lower casing is equipped with an oil outlet, which is connected to the feed inlet pipe of the filter press 33. The nitrogen storage tank 31 is connected to the air inlet pipe of the filter press 33. The filter press 33 includes: a tank body, a cover, a filter screen frame, and a pressure gauge 333. The cover is detachable and installed on the open top surface of the tank body. The pressure gauge 333 is mounted on the cover. The filter screen frame is housed within the tank body, and a sealing ring 34 is fitted around its perimeter, sealing the upper and lower cavities of the tank body. Filter cloth 313 is laid inside the filter screen frame. A conical bottom 316 is provided on the bottom surface of the tank body, with an outlet located in the center of the conical bottom 316. The outlet is connected to the fresh oil storage tank 32 via a pipeline, and a filter press pump 341 is installed on the connected pipeline. By pressurizing the filter press 33 with nitrogen storage tank 31, the edible oil can be prevented from contacting air, thus protecting the edible oil and reducing the rate of increase in oxidation value.
[0026] In one specific embodiment, the disassembly and connection of the can body and the cover body are achieved by corresponding fixed protrusions 332 and connecting bolts 331: multiple fixed protrusions 332 are symmetrically arranged on the can body and the cover body respectively. The fixed protrusions 332 are provided with through holes, and the threaded structure in the through holes is threadedly connected to the connecting bolts 331 inserted in the through holes, thereby realizing the disassembly and connection of the can body and the cover body.
[0027] After edible oil is injected into the upper part of the filter press tank 33, nitrogen is added and a certain pressure is maintained. The filter press pump 341 is then turned on. Under the downward pressure of the air in the upper chamber and the outward suction of the filter press pump 341, the edible oil is forced to pass directionally through the filter cloth on the filter screen frame, thereby effectively filtering and removing various impurities from the edible oil. This device can achieve uniform directional movement force applied to the edible oil, realizing comprehensive and uniform filtration.
[0028] In one specific embodiment, the filter press frame includes: a lifting rod 311, a pressing mesh 312, a supporting mesh plate 314, a supporting frame 315, and a supporting ring 343. The supporting frame 315 is mounted on the bottom surface of the supporting mesh plate 314, and the supporting ring 343 is mounted on the bottom surface of the supporting frame 315. The lifting rod 311 is installed on the conical bottom 316 inside the filter press tank 33. By setting the supporting ring 343, the contact area between the supporting frame 315 and the conical bottom 316 can be increased, improving the reliability of the stress distribution. The specific dimensions of this structure are based on its ability to withstand the pressure of the filter press, and can be adjusted by those skilled in the art as needed. The bottom of the lifting rod 311 is located at the center of the supporting frame 315. The pressing mesh 312, the supporting mesh plate 314, and the filter cloth 313 are threaded onto the lifting rod 311. A ring body is provided on the top surface of the lifting rod 311 for threaded detachment connection with the rod body. Specifically, a threaded hole can be provided at the connection point of the ring body, and a threaded structure can be provided at the top of the rod body to achieve threaded detachment connection. The filter press 312 and support plate 314 are stacked, with filter cloth 313 laid flat between them. The sealing ring 34 is made of soft silicone. After assembling the filter press frame, the sealing ring 34 is fitted onto the outer periphery of the filter press frame, and then the entire filter press frame is placed into the filter press tank 33. A small gap is left between the filter press 312, support plate 314, filter cloth 313 and the lifting rod 311. Due to the small area, the amount of edible oil passing through this area is negligible. This filter press frame structure ensures that the filter cake 313 remains flat during filtration and that the force is evenly distributed. It also facilitates the removal of the filter press frame when it needs to be disassembled and cleaned after filtration. Multiple layers of filter cloth 313 can be laid according to filtration needs.
[0029] In one specific embodiment, a motor-driven cooling fan 131 is provided on the opposite side of the lower housing to reduce the temperature in the lower housing and prevent the crushing device and oil pressing device from shutting down due to excessive temperature.
[0030] In one specific embodiment, it includes: support legs 322; multiple support legs 322 are provided on the bottom surface of the filter press 33 for lifting the filter press 33 off the ground to facilitate material discharge.
[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
