Description

Technical Field

[0001] The present invention relates to a peanut oil press that can realize the integrated functions of peanut chopping, steaming and frying, oil pressing and slag removal, and belongs to the technical field of peanut oil pressing processing. In particular, it relates to a peanut oil press that crushes peanuts through a chopping component, steams and fries the chopped peanuts through a steaming and frying component, squeezes and extracts oil from the steamed and fried peanuts through an oil pressing component, and cleans and collects oil residue produced after oil pressing through a slag removal component, thereby integrating chopping, steaming and frying, oil pressing and slag removal, and improving oil output efficiency and automation. Background Art

[0002] A peanut oil press is a mechanical device that uses external mechanical force to increase the temperature, activate oil molecules, and squeeze oil out of peanuts. Before pressing the 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 then stir-fry them. Finally, the fried peanuts are placed in the peanut oil press for pressing to increase the oil yield and improve the oil quality. The peanut oil press itself does not have the function of chopping and steaming peanuts, so additional manual labor or other machines are required to complete the peanut chopping and steaming steps, and the integration of chopping, steaming and pressing cannot be achieved. The labor cost is high, the pressing efficiency is low, the degree of automation is low, and the risk of cross-contamination caused by multiple manual operations is high.

[0003] Publication No. CN108859211A discloses a peanut oil press, comprising a housing assembly and a transmission assembly. The housing assembly comprises a storage box, a cover plate, a storage barrel, a support column, and an inner barrel. The storage box is provided with an oil outlet pipe on its outer surface, and the storage box and the oil outlet pipe are welded and fixed. Two support columns are located on the upper surface of the storage box and are welded and fixed to the storage box. The cover plate is fixed to the end of the support column away from the storage box. The storage barrel is provided on the upper surface of the storage box near the support column, and the storage box and the storage barrel are threadedly connected. The above-mentioned peanut oil press can heat the peanuts to a certain temperature using a heating pipe before oil extraction, but it cannot chop or steam the peanuts. The peanuts have a small surface area, making it difficult for oil molecules to be released from the peanut cells. The peanuts contain a large amount of water, which easily affects the quality of the peanut oil. The oil requires a large pressure to be released during extraction, resulting in a low oil yield.

[0007] Second, the steaming and frying component can increase the temperature of the chopped peanuts, reduce the viscosity of the oil, enhance the fluidity, and at the same time destroy the cell structure in the peanuts, making it easier for the oil to be released from the peanuts during pressing, thereby increasing the oil yield; and can improve the taste and color of the peanut oil.

[0008] 3. The eccentric pressing of steamed and fried peanuts by the oil pressing component can make the pressing wheel apply force to the peanuts more evenly during the pressing process, increase the contact area between the peanuts and the pressing wheel and the pressing time, and achieve a higher oil yield.

[0009] 4. The integration of chopping, steaming, pressing and slag removal can improve the pressing efficiency and degree of automation, and is suitable for batch pressing of peanuts. BRIEF DESCRIPTION OF THE DRAWINGS

The push plate on the part of the pressing wheel that is not in contact with the inner wall of the oil pressing bin pops out from the push plate placement groove under the action of the spring, thereby supporting the pressing wheel. At the same time, the peanuts entering the oil pressing bin can be stirred as the pressing wheel rotates, thereby reducing the accumulation of peanuts in a certain position; the pressing wheel squeezes the steamed and fried peanuts entering the oil pressing bin, thereby extracting peanut oil, and the squeezed peanut oil enters the oil outlet through the filter screen and then enters the oil storage tank through the oil outlet; the second flow sensor collects second flow data of the peanut oil entering the oil outlet, and sends the collected second flow data signal to the signal converter.

The hollow arc-shaped blade can reduce the weight of the blade, reduce the rotational resistance of the blade, make the blade more stable when rotating at high speed, thereby enhancing the cutting force and helping to chop peanuts more efficiently; the thickness of the blade gradually decreases from one side to the other, making the edge of the blade sharper, which can more effectively cut the peanut fibers, allowing the blade to gradually penetrate into the interior of the peanuts during the cutting process, achieving a more uniform chopping effect and improving the oil yield in the subsequent pressing process; The other end of the oil outlet is detachably placed at the center of the top surface of the oil storage tank and is connected to the center of the top surface of the oil storage tank. The oil storage tank is designed with a transparent material, which makes it easier for workers to observe the level of peanut oil in the oil storage tank and avoid the risk of peanut oil flowing back from the oil outlet into the oil pressing bin due to excessively high oil level. Through the transparent oil storage tank, workers can also intuitively observe the color, clarity and other quality indicators of the peanut oil, which helps to promptly discover and deal with impurities or abnormalities in the peanut oil and adjust the parameters of various components to ensure the quality of the final product.
