[0002] Peanuts contain a large amount of oil and protein, making them an excellent oilseed crop. In peanut oil production, an oil press is used to squeeze the peanuts, separating the oil from other components through crushing and squeezing to finally obtain edible oil.

[0003] Conventional oil presses are screw presses, which use a screw to compress peanuts to obtain peanut oil. However, existing screw presses have limited compression force, resulting in a low peanut oil yield. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a peanut oil press that can crush peanuts, reduce the squeezing force required by the spiral blades of the screw shaft, and increase the oil yield of peanut oil.

[0005] A peanut oil press according to an embodiment of the present invention includes: a first extrusion mechanism, comprising a material box, two first extrusion rollers located within the material box, and a second extrusion roller located below the first extrusion rollers, the two first extrusion rollers being distributed vertically, the second extrusion roller being arranged between the two first extrusion rollers, the central axes of the two first extrusion rollers and the second extrusion roller being triangularly distributed, and the first extrusion rollers and the second extrusion rollers being rolled relative to each other; a second extrusion mechanism, comprising a spiral shaft, a material cylinder fitted on the radial outer surface of the spiral shaft, and a first motor driving the spiral shaft to rotate, the spiral shaft having spiral blades, the pitch of the spiral blades being gradually reduced along the extrusion direction, the material cylinder being located below the material box and communicating with the material box, the material cylinder being provided with a first oil outlet; and a collection mechanism, comprising a liquid collection tank, the liquid collection tank being used to collect peanut oil flowing out of the first oil outlet.

[0027] A peanut oil press according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] Reference Figure 1 The present invention aims to provide an embodiment of a peanut oil press.

[0029] A peanut oil press according to an embodiment of the present invention includes a first pressing mechanism, a second pressing mechanism, and a collecting mechanism.

[0030] The first extrusion mechanism includes a material box 100, two first extrusion rollers 110 located inside the material box 100, and a second extrusion roller 120 located below the first extrusion rollers 110. The two first extrusion rollers 110 are distributed vertically, and the second extrusion roller 120 is arranged between the two first extrusion rollers 110. The central axes of the two first extrusion rollers 110 and the second extrusion roller 120 are triangularly distributed, and the first extrusion rollers 110 and the second extrusion roller 120 are arranged to roll relative to each other.

[0031] Therefore, peanuts can enter the feed box 100 and be rolled and crushed by the first extrusion roller 110 and the second extrusion roller 120. Since the central axes of the two first extrusion rollers 110 and the second extrusion roller 120 are triangularly distributed, the peanuts are rolled twice, which makes the peanuts fully crushed. This helps to reduce the extrusion pressure required by the spiral blades 160 of the spiral shaft 130. In other words, under the same power output, the spiral blades 160 of the spiral shaft 130 can squeeze peanuts with a higher oil yield, thus improving the oil yield of peanuts squeezed by the spiral blades 160.

[0032] In some embodiments of this utility model, reference is made to Figure 3The first extrusion mechanism also includes a driving gear 270 and a driven gear 280 that mesh with each other, and a second motor 290 that drives the driving gear 270 to rotate. The driving gear 270 is coaxially arranged on the second extrusion roller 120, and the driven gear 280 is coaxially arranged on the first extrusion roller 110.

[0033] Therefore, the second motor 290 drives the drive gear 270 to rotate, and the drive gear 270 and the driven gear 280 mesh and transmit power, so that the drive gear 270 drives the second extrusion roller 120 to rotate, and the driven gear 280 drives the first extrusion roller 110 to rotate. The first extrusion roller 110 and the second extrusion roller 120 rotate relative to each other, crushing the peanuts.

[0034] In some embodiments of this utility model, the radial outer surface of the first extrusion roller 110 is provided with teeth 190, thereby making it easier for the first extrusion roller 110 to crush peanuts and improve peanut extrusion efficiency.

[0035] In some embodiments of this utility model, a guide bucket 200 is provided above the material box 100. The guide bucket 200 is gradually narrowed from top to bottom, thereby guiding the peanuts into the material box 100, which is beneficial for the first extrusion mechanism to extrude the peanuts.

[0036] The second extrusion mechanism includes a screw shaft 130, a cylinder 140 fitted on the radial outer surface of the screw shaft 130, and a first motor 150 that drives the screw shaft 130 to rotate. The screw shaft 130 has a screw blade 160 with a gradually decreasing pitch along the extrusion direction. The cylinder 140 is located below the material box 100 and is connected to the material box 100. The cylinder 140 is provided with a first oil outlet 170.

[0037] Therefore, the first motor 150 drives the spiral shaft 130 to rotate, and the spiral shaft 130 further squeezes the peanuts inside the barrel 140 through the spiral blades 160 to produce peanut oil. The spiral blades 160 are gradually narrowed, so that the extrusion pressure on the peanuts gradually increases, which is beneficial to increasing the oil output.

[0038] In some embodiments of this utility model, a screw conveyor 210 is provided at the discharge end of the screw shaft 130. The screw conveyor 210 is used to transport peanut residue. The screw conveyor 210 has a waste residue outlet 220, which receives the peanut residue extruded from the screw shaft 130.

[0039] Therefore, the peanut residue extruded by the screw shaft 130 can enter the waste residue inlet 220 and be transported to the designated location by the screw conveyor 210.

[0040] In some embodiments of this utility model, a waste residue box 230 is provided below the discharge port of the screw conveyor 210. The waste residue box 230 is used to collect peanut residue, thereby facilitating the centralized collection of peanut residue.

[0041] The collection mechanism includes a liquid collection tank 180, which is used to collect the peanut oil flowing out of the first oil outlet 170.

[0042] In some embodiments of this utility model, the feed cylinder 140 is connected to a guide groove 300, the guide groove 300 is inclined, the bottom end of the guide groove 300 is located near the liquid collection tank 180, and the first oil outlet 170 is located at the bottom end of the guide groove 300, thereby facilitating the collection of peanut oil.

[0043] In some embodiments of this utility model, a filter tank 240 is provided on the top of the liquid collection tank 180, and a filter screen is provided at the bottom of the filter tank 240.

[0044] Therefore, the filter screen can remove the residue from peanut oil, resulting in purer peanut oil.

[0045] In some embodiments of this utility model, reference is made to Figure 2 It also includes a slag pushing mechanism, which includes a push plate 250 and a cylinder 260 that drives the push plate 250 to move from one side of the filter screen to the other side. The push plate 250 is slidably disposed on the top of the filter screen.

[0046] Therefore, by using cylinder 260 to drive push plate 250 to move, push plate 250 can move peanut crumbs on the top of filter screen to one side, making it convenient to clean peanut crumbs from filter screen.
