Description

Technical Field

[0001] The invention discloses a multi-stage fine filtering structure of a peanut oil press and a peanut oil press, which relates to a fine filtering structure installed on the peanut oil press, and belongs to the technical field of peanut oil pressing processing, and particularly relates to a fine filtering structure which filters peanut oil multiple times through a filtering layer, a filtering net and a filtering plate to improve the quality of the peanut oil. Background Art

[0002] Peanut oil press is a mechanical device that uses mechanical external force to increase the temperature, activate oil molecules, and squeeze oil out of peanuts. Before squeezing peanuts, the existing peanut oil press needs to first chop the peanuts, then add a certain amount of clean water to the chopped peanuts, steam them, and stir-fry them. Finally, the fried peanuts are put into the peanut oil press for squeezing to increase the oil yield and improve the quality of the oil. The peanut oil press itself does not have the function of chopping and steaming peanuts, so it is necessary to complete the peanut chopping and steaming steps manually or by other machines. It cannot achieve the integration of chopping, steaming and squeezing, and has high labor costs, low squeezing efficiency, low degree of automation, and a high risk of cross-contamination during multiple manual operations.

[0003] Announcement No. CN108859211A discloses a peanut oil press, including a shell assembly and a transmission assembly, wherein the shell assembly is composed of a placement box, a cover plate, a placement barrel, a support column and an inner barrel, an oil outlet pipe is provided on the outer surface of the placement box, the placement box and the oil outlet pipe are welded and fixed, two support columns are located on the upper surface of the placement box and are welded and fixed to the placement box, the cover plate is fixedly provided on one end of the support column away from the placement box, the placement barrel is provided on the side of the upper surface of the placement box close to the support column, and the placement box and the placement barrel are threadedly connected. The above-mentioned peanut oil press can heat the peanuts to a certain temperature through a heating tube before oil extraction, but it cannot chop and steam the peanuts. The surface area of ​​the peanuts is small, and the oil molecules are not easy to be released from the peanut cells. The water content inside the peanuts is large, which easily affects the quality of the peanut oil. The oil needs a large pressure to be released during squeezing, and the oil yield is low.

[0004] In order to improve the above problems, the applicant filed a Chinese invention patent application entitled "A Peanut Oil Press". The pressing wheel squeezes the steamed and fried peanuts entering the oil pressing bin to extract peanut oil. The squeezed peanut oil enters the oil outlet through the filter and then enters the oil storage tank. The peanut oil squeezed out by the peanut oil press is only filtered once by the filter, which can remove some larger particles and impurities in the peanut oil, but does not further finely filter the peanut oil. The peanut oil entering the oil storage tank needs to be left to stand for a period of time and then manually filtered multiple times, which is time-consuming and labor-intensive, and the quality of the peanut oil is low.

[0014] The difference between this embodiment and the first embodiment is that a sealing ring (53) is arranged between the edge of the filter plate (48) and the inner side surface of the filter box (47), and the sealing ring (53) is made of rubber. When in use, the sealing ring (53) made of rubber has good elasticity and sealing performance, and can be tightly fitted between the edge of the filter plate (48) and the inner side surface of the filter box (47), effectively preventing peanut oil that has not been filtered through the second filter hole or foreign particles generated after filtering from flowing into the oil storage box (16) through the gap, thereby improving the quality of the peanut oil. At the same time, the sealing ring (53) can increase the connection stability between the filter plate (48) and the filter box (47), and reduce loosening or dislocation caused by vibration or impact generated by the rotation of the oil scraper plate (49) and the third rotating shaft (46). The inner diameter of the first filter holes on the plurality of filter layers (44) is designed to gradually decrease from the top surface of the oil pressing bin (21) to the location of the oil outlet (15). The plurality of filter layers (44) can filter impurity particles of different sizes from the peanut oil layer by layer, thereby achieving a better filtering effect on the peanut oil and improving the quality of the peanut oil. The first filter holes formed on two adjacent filter layers (44) are designed to be arranged in a staggered manner. The staggered arrangement of the first filter holes can increase the path length of the peanut oil when it passes through the multiple filter layers (44), making it easier for impurity particles in the peanut oil to be intercepted and filtered, thereby improving the filtering efficiency and effect; at the same time, it also helps to reduce the risk of adjacent first filter holes on the filter layer (44) being blocked by impurity particles at the same time, thereby extending the service life of the filter layer (44); and it can avoid the phenomenon of uneven filtering caused by repeated flow of peanut oil at the same position, thereby achieving a better filtering effect of the filter layer (44); The first filter hole is a pear-shaped hole with a thick top and a thin bottom, which can reduce the accumulation and clogging of foreign particles in the first filter hole, extend the service life of the filter layer (44), and can effectively filter foreign particles of different sizes, so that the filter layer (44) has a better filtering effect; The thickness of the scraper plate (49) is designed to gradually decrease from the top surface to the bottom surface. When the bottom surface with a smaller thickness is in sliding contact with the filter plate (48), the contact area between the bottom surface of the scraper plate (49) and the filter plate (48) can be reduced, thereby reducing sliding resistance, making the oil scraping process smoother and improving the oil scraping efficiency.

[0015] The peanut oil can be filtered multiple times through the filter layer (44), the filter screen (14) and the filter plate (48), thereby improving the quality of the peanut oil.
