Description

Technical Field

[0001] The invention relates to the technical field of pressing equipment, in particular to automated pressing equipment and a method for producing peanut oil. Background Art

[0002] Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is a relatively easy to digest edible oil. Judging from the above content, the fatty acid composition of peanut oil is relatively good and it is easy for the human body to digest and absorb. Peanut oil also contains sterols, wheat germ phenol, phospholipids, vitamin E, choline and other substances beneficial to the human body. Regular consumption of peanut oil can prevent skin wrinkling and aging, protect blood vessel walls, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease. The choline in peanut oil can also improve the human brain's memory and delay brain function decline.

[0003] In the prior art, a Chinese patent with publication number "CN109159446A" discloses a peanut oil pressing device that is convenient for secondary feeding, which is equipped with a feeding bin, a rocker, a tamping rod and a grinding bin. After the peanuts are poured into the feeding bin, the tamping rod is driven by a first motor to make up and down reciprocating vertical movements to push the peanuts at the bottom of the feeding bin into the grinding bin. After the peanuts enter the grinding bin, the peanuts are rubbed between the lower grinding disc and the upper grinding disc by the rotation of the lower grinding disc, so that the peanuts can be quickly crushed into peanut fragments of the same size, which is convenient for subsequent secondary discharging and squeezing. The use is more convenient and efficient, and solves the problem that the existing squeezing equipment lacks pre-crushing measures for peanuts, which easily causes uneven squeezing of peanuts and waste of oil caused by failure to completely squeeze out some peanuts.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] When peanut oil is pressed, the peeled and cleaned peanuts are usually crushed and then roasted. The roasted peanuts are pressed by a pressing device. When pressing the peanuts, most of the methods are to put the peanuts into a pressing bin and then press the peanuts by a pressing plate. However, after the peanuts in the pressing bin are pressed, part of the peanut oil in the peanuts is squeezed out, and the remaining solid part is squeezed into a solid block. When the pressing plate is used for secondary extrusion, the original peanuts are squeezed into a block, resulting in poor effect when squeezed again. Summary of the invention

The cooperation between the spiral blade 27 and the lower barrel 21 and by pressing the spiral blade 27, the principle that the spiral blade 27 can be both rotated and rotated is the same as the operating principle of the children's toy hand-pushed flying saucer.

[0052] In this embodiment, when the hydraulic cylinder 8 drives the pressure plate 6 on the lifting column 9 to press down the peanuts in the pressing bin 502, the lifting column 9 will synchronously drive the lifting plate 37 to move, and the spiral blade 27 on the lifting plate 37 will use the bearing 26 and the spiral blade 27 to be threadedly installed with the discharge barrel 21, so that the spiral blade 27 is in a downward rotating state, and the dragon roller 28 on the spiral blade 27 will synchronously follow the movement of the spiral blade 27, and use the dragon roller 28 to accelerate the discharge speed of the peanuts in the discharge barrel 21, while also preventing too many peanuts from being blocked in the discharge pipe 22.

[0053] A peanut oil pressing method, based on the above description of an automated pressing device for peanut oil production, comprises the following pressing steps;

[0054] S1. When in use, the crushed peanuts are put into the lower barrel 21, and then enter the lower pressing chamber 502 through the lower barrel 22, the bellows 23 and the connecting pipe 24. The hydraulic cylinder 8 in the pushing assembly drives the pressing plate 6 on the lifting column 9 to press down the peanuts in the lower pressing chamber 502, and the produced peanut oil will enter the oil receiving barrel 34 through the oil discharge pipe 31, the telescopic hose 30 and the oil receiving pipe;

[0055] S2. After the pressing plate 6 is squeezed once, the crushing rod 12 on the lifting plate 37 in the lifting chamber 10 is driven to extend from the pressing plate 6 by the first electric push rod 11. The crushing rod 12 is located in the peanut residue at the bottom of the lower pressing chamber 502. The crushing rod 12 is driven to rise and fall by the first electric push rod 11, and the crushing rod 12 is used to crush the peanut residue that is stuck together.

[0056] S3. When the crushing rod 12 penetrates into the lower pressing chamber 502, the expansion plate 15 on the crushing rod 12 is expanded outward by the torsion of the torsion spring 16, and then the tooth plate 20 is driven to move horizontally by the second electric push rod 19. The tooth plate 20 is meshed with the gear ring 17, so that the lower pressing chamber 502 is in a reciprocating rotation state, and the peanut residue in the lower pressing chamber 502 is stirred by the crushing rod 12. After the stirring is completed, the crushing rod 12 is restored to its original position, and the pressed plate 6 is used to squeeze the stirred peanut residue;

[0057] S4. When the lifting column 9 is in the process of reciprocating lifting, the bearing 26 will press down the spiral blade 27, and the spiral blade 27 will rotate through the discharge barrel 21. The dragon roller 28 on the spiral blade 27 will move synchronously with the spiral blade 27, and the dragon roller 28 will accelerate the discharge speed of the peanuts in the discharge barrel 21, and also prevent too many peanuts from clogging the discharge tube 22;

[0060] When in use, the crushed and roasted peanuts are put into the lower barrel 21, and then enter the lower pressing chamber 502 through the lower pipe 22, the bellows 23 and the connecting pipe 24. The hydraulic cylinder 8 drives the pressing plate 6 on the lifting column 9 to press down the peanuts in the lower pressing chamber 502, and the produced peanut oil will enter the oil receiving barrel 34 through the oil discharge pipe 31, the telescopic hose 30 and the oil receiving pipe, and the peanut residue at the bottom of the lower pressing chamber 502 can be discharged into the residue receiving barrel 38 through the residue discharge pipe 36.

[0061] After the pressing plate 6 squeezes the peanuts at the bottom of the lower pressing chamber 502 once, the pressing plate 6 is located inside the upper pressing chamber 501, and then the first electric push rod 11 is used to drive the crushing rod 12 on the lifting plate 37 in the lifting chamber 10 to extend from the pressing plate 6, and the crushing rod 12 will be located in the peanut residue at the bottom of the lower pressing chamber 502. The crushing rod 12 is reciprocated by the first electric push rod 11 to lift and lower, and the crushing rod 12 is used to crush the peanut residues that are stuck together;

[0062] When the crushing rod 12 penetrates into the lower pressing chamber 502, the expansion plate 15 on the crushing rod 12 is expanded outward by the torsion of the torsion spring 16, and then the tooth plate 20 is driven to move horizontally by the second electric push rod 19. The tooth plate 20 is meshed with the gear ring 17, so that the lower pressing chamber 502 is in a reciprocating rotation state, and the peanut residue in the lower pressing chamber 502 is stirred by the crushing rod 12. After the stirring is completed, the crushing rod 12 is restored to its original position, and the pressed plate 6 is used to squeeze the stirred peanut residue.

[0063] When the lifting column 9 is in the process of reciprocating lifting, the lifting column 9 will synchronously drive the lifting plate 37 to move, and the spiral blade 27 on the lifting plate 37 will use the bearing 26 and the spiral blade 27 to be threadedly installed with the discharge barrel 21, so that the spiral blade 27 is in a downward rotating state, and the dragon roller 28 on the spiral blade 27 will synchronously follow the movement of the spiral blade 27. The conveying function of the dragon roller 28 and the pushing function of the dragon roller 28 can speed up the discharge speed of peanuts in the discharge barrel 21, and at the same time, it also prevents excessive peanuts from being blocked in the discharge pipe 22.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
