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". Multiple blade connecting sleeves are equidistantly arranged on the side of the first rotating shaft, and one end of multiple blades is equidistantly arranged on the side of each blade connecting sleeve. The controller starts the first rotating motor, and the first rotating motor drives the first rotating shaft to rotate, and the first rotating shaft drives the blades to rotate to finely crush the peanuts. However, there is a gap between the two adjacent blade connecting sleeves in the above peanut oil press, resulting in that the peanuts between the two adjacent sets of blades cannot be completely in contact with the blades and cannot be effectively crushed. The structure of the peanut cells cannot be completely destroyed, which affects the extraction of peanut oil in the subsequent oil pressing process and the oil yield is low. Summary of the invention

Preferably, a plurality of flow-disturbing transverse grooves are formed on the surface of the second spiral blade (45) at equal intervals in the transverse direction, the length of the flow-disturbing transverse grooves is smaller than the width of the second spiral blade (45), the groove bottom of the flow-disturbing transverse grooves is wide and the groove mouth is narrow, First blades are respectively disposed on both sides of the first spiral blade (44), and both ends of the first blade are respectively close to both ends of the first spiral blade (44). Preferably, a plurality of flow-disturbing particles are evenly arranged on the surface of the first blade, and the flow-disturbing particles are hemispherical structures; When in use, the crushing structure is installed on the peanut oil press, and the shelled peanuts are poured into the crushing box (3) from the feed port (1). The controller starts the first rotating motor (2), and the first rotating motor (2) drives the first rotating shaft (25) to rotate. The first rotating shaft (25) drives the fourth spiral blade (47), the third spiral blade (46), the second spiral blade (45), and the first spiral blade (44) to rotate. During the rotation process, the fourth blade chops the peanuts it contacts, the third blade and one of the second blades chops part of the peanuts that slide into the gap between the third spiral blade (46) and the second spiral blade (45), and the other second blade and one of the first blades chops part of the peanuts that slide into the gap between the second spiral blade (45) and the first spiral blade (44). The other first blade located at the edge can chop other peanuts, thereby increasing the contact area with the peanuts, so that the peanuts are effectively crushed, and the structure of the peanut cells can be completely destroyed, which is conducive to the extraction of peanut oil in the subsequent oil pressing process and improves the oil yield. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: the first spiral blade (44) is provided with anti-sticking holes (48); the anti-sticking holes (48) are provided in a plurality of groups, the plurality of groups of anti-sticking holes (48) are arranged equidistantly along the width direction of the first spiral blade (44), each group has a plurality of anti-sticking holes (48), the plurality of anti-sticking holes (48) are arranged equidistantly along the length direction of the first spiral blade (44), and the inner diameters of two adjacent groups of anti-sticking holes (48) are different; when in use, the anti-sticking holes (48) can reduce the adhesion of the peanuts with higher humidity to the first spiral blade (44), thereby ensuring that the first blade can continuously and effectively crush the peanuts, thereby improving the crushing efficiency; at the same time, the anti-sticking holes (48) can reduce the adhesion of the crushed peanuts to the first spiral blade (44), so that the crushed peanuts can completely enter the steaming and frying box (10), thereby reducing the residual peanuts on the first spiral blade (44); Example 3

[0015] The difference between this embodiment and embodiment 1 is that: the second spiral blade (45) is replaced by a spiral boss blade (49), the height of the spiral boss blade (49) gradually decreases from the center to both sides, a raised blade is arranged at the center of the spiral boss blade (49), and the thickness of the raised blade gradually decreases from one side connected to the spiral boss blade (49) to the other side; when in use, the spiral boss blade (49) can more effectively contact the peanuts and apply a crushing force during the rotation process, and at the same time, in combination with the raised blade, the peanuts can be crushed more finely, thereby improving the crushing efficiency of the peanuts; The design of gradually increasing the heights of the fourth spiral blade (47), the third spiral blade (46), the second spiral blade (45), and the first spiral blade (44) enables spiral blades of different heights to undertake different crushing tasks. The higher spiral blades mainly perform preliminary crushing on the peanuts entering the crushing box (3) to reduce their volume and hardness. As the peanuts gradually move forward, they will pass through a plurality of spiral blades of gradually decreasing heights in sequence, and can be further crushed. The graded crushing method makes the entire crushing process more efficient and orderly, thereby improving the crushing efficiency. The two adjacent fourth blades are designed to have different heights and different orientations. The fourth blades of different heights can generate different shearing forces and impact forces during the rotation process, thereby crushing the peanuts at multiple levels and angles, which helps to reduce the particle size of the peanuts more quickly and improve the crushing efficiency. The fourth blades of different orientations can generate different cutting paths and angles during the rotation, further enhancing the crushing effect, helping to break the internal structure of the peanuts, making them easier to squeeze and improving the squeezing efficiency. The fourth blades of different heights and orientations can form a certain peanut flow channel during the rotation, guiding the peanuts to move along a predetermined path, which helps to reduce the retention and blockage of the peanuts in the crushing box (3); The third blade is designed with a sawtooth structure, which can generate strong shear force and impact force during the rotation process, so as to crush the peanuts more effectively. The sharp edge of the sawtooth can more easily cut into the inside of the peanuts, accelerate the crushing process, and improve the crushing efficiency; The thickness of the third blade is designed to gradually decrease from the side connected to the third spiral blade (46) to the other side, so that the third blade is subjected to more uniform force during the cutting process, reducing the risk of wear and breakage due to excessive local force. The side with greater thickness can increase the stability of the connection with the third spiral blade (46) and reduce the connection from falling off and loosening, while the other side with less thickness can more easily cut into the interior of the peanuts, reducing the crushing resistance and improving the crushing efficiency. A plurality of crushing teeth are evenly arranged on the surface of the third spiral blade (46), and the width of the crushing teeth is designed to gradually decrease from one end connected to the third spiral blade (46) to the other end. During the rotation process, the crushing teeth can guide the peanuts to move along a certain trajectory, promote the dispersion of the peanuts, and help reduce the accumulation and blockage of the peanuts on the surface of the third spiral blade (46); the end with a larger width can increase the connection stability with the third spiral blade (46), reduce the connection from falling off or loosening, and the other end with a smaller width can gradually penetrate into the interior of the peanuts, ensuring that the peanuts are fully crushed; the gradual reduction in width also helps to reduce the resistance generated by the crushing teeth in the process of crushing the peanuts, thereby reducing the wear of the crushing teeth; The second blade is designed with a structure that is curved multiple times from one side to the other side, which can increase the contact area between the second blade and the peanuts, and can also make the second blade produce a complex motion trajectory during the rotation process, so as to crush the peanuts at multiple angles and levels, thereby improving the crushing efficiency. The curved structure is also helpful in guiding the flow of peanuts and reducing the occurrence of blockage. The surface of the second spiral blade (45) is provided with a plurality of flow-disturbing transverse grooves at equal intervals in the transverse direction, wherein the length of the flow-disturbing transverse grooves is less than the width of the second spiral blade (45), and the design of the flow-disturbing transverse grooves having a wide groove bottom and a narrow groove opening can break the attachment and accumulation of peanuts on the surface of the second spiral blade (45), thereby promoting the flow and dispersion of peanuts; at the same time, the design of the groove bottom being wide and the groove opening being narrow helps to reduce the retention time of peanuts in the flow-disturbing transverse grooves, thereby further improving the fluidity of peanuts; A plurality of flow-disturbing particles are evenly arranged on the surface of the first blade. The flow-disturbing particles are designed with a hemispherical structure and can generate tiny eddies and disturbances during rotation, which helps to break the surface tension of the peanuts and promote the dispersion and crushing of the peanuts; at the same time, it can reduce the sliding friction of the peanuts on the surface of the first blade and reduce the wear of the first blade.

[0016] The purpose is to achieve the purpose of being able to drive the fourth spiral blade (47), the third spiral blade (46), the second spiral blade (45) and the first spiral blade (44) to rotate through the first rotating shaft (25), thereby driving the fourth blade, the third blade, the second blade and the first blade to cut the peanuts that they come into contact with, thereby increasing the contact area with the peanuts, enabling the peanuts to be crushed more effectively, and improving the crushing efficiency.

The data processor processes the received first time data. The digital signal is processed, and the collected first time data is compared with the preset first time threshold. If they are equal, it means that the peanuts are chopped. The controller controls the first rotating motor (2) to stop rotating. The pull plate (6) is pulled out of the control valve (22) by manually holding the handle (7) in the first discharge control assembly. After the pull plate (6) is pulled out, the blocking plate (28) blocks one end of the control valve (22) under the rebound action of the second spring (30).

When the pressing wheel (13) contacts the inner wall of the oil pressing bin (21) to squeeze the peanuts, the push plate (11) is pushed into the push plate (11) placement groove. The push plate (11) on the portion of the pressing wheel (13) that is not in contact with the inner wall of the oil pressing bin (21) pops out from the push plate (11) placement groove under the action of the spring, thereby supporting the pressing wheel (13) and stirring the peanuts entering the oil pressing bin (21) as the pressing wheel (13) rotates, thereby reducing the accumulation of peanuts at a certain position.

The second flow sensor collects second flow data of the peanut oil entering the oil outlet (15), and sends the collected second flow data signal to the signal converter. The signal converter converts the electrical signal of the received second flow data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received second flow data and compares the collected second flow data with a preset flow threshold. If the value is less than the preset flow threshold, it indicates that the peanut oil pressing is completed.

Through the transparent oil storage tank (16), the staff can also visually observe the color, clarity and other quality indicators of the peanut oil, which helps to timely discover and deal with impurities or abnormal conditions in the peanut oil and adjust the parameters of each component to ensure the quality of the final product. When the oil level of the oil storage tank (16) reaches a certain height, the detachable connection with the other end of the oil outlet (15) makes it easier to replace the new oil storage tank (16). The push plate (11) and the first spring (12) cooperate with the design of the pressing wheel (13), and the third rotating motor (35) drives the pressing wheel (13) to rotate along the inner wall of the oil pressing bin (21). When the pressing wheel (13) contacts the inner wall of the oil pressing bin (21) to squeeze the peanuts, the push plate (11) is pushed into the push plate (11) placement groove, and the push plate (11) on the part of the pressing wheel (13) that does not contact the inner wall of the oil pressing bin (21) pops out from the push plate (11) placement groove under the action of the spring, which not only supports the pressing wheel (13), but also can support the peanuts entering the oil pressing bin (21) during the rotation of the pressing wheel (13). The peanuts are stirred to reduce the accumulation of peanuts at a certain position; and after the oil pressing is completed, the third rotating motor (35) drives the pressing wheel (13) to rotate along the inner wall of the oil pressing bin (21), and the push plate (11) on the part of the pressing wheel (13) that is not in contact with the inner wall of the oil pressing bin (21) can also scrape and clean the oil residue or oil cake produced after oil pressing and attached to the inner wall of the oil pressing bin (21), so that the oil residue or oil cake is driven by the push plate (11) to enter the residue collection box (41) from the sealing port, and the oil residue or oil cake is collected and recycled, which can reduce the residue residue remaining on the inner wall of the oil pressing bin (21), and help to improve the oil yield of subsequent peanut oil pressing; The peanuts can be crushed by the chopping component, the chopped peanuts can be steamed and fried by the steaming and frying component, the steaming and frying peanuts can be squeezed and oiled by the oil pressing component, and the oil residue produced after oil pressing can be cleaned and collected by the residue removing component, so that the chopping, steaming and frying, oil pressing and residue removing are integrated, thereby improving the oil output efficiency and the degree of automation.
