[0044] Embodiment 2:

[0045] Reference Figure 1-Figure 6 , which is basically the same as the first embodiment, and further, a specific implementation scheme for causing the pressing plate 7 to vibrate is specifically added.

[0046] The circumferential outer wall of the above-mentioned pressure plate 7 is provided with a plurality of sliding holes 13 arranged at equal intervals.

[0047] Specifically, during the rotation of the pressing plate 7, the pressing plate 7 will drive the sliding column 14 to revolve around its axis, and the ends of the plurality of sliding columns 14 will slide over the column 19 in sequence. When pressing against the column 19, the sliding column 14 will slide into the sliding hole 13. When passing over the column 19, the first spring 15 will drive the sliding column 14 to slide back and forth, so that the sliding column 14 can slide back and forth in the sliding hole 13 when sliding over the column 19.

On the one hand, the stability between the pressing plates 7 is improved, and on the other hand, the vibration of the pressing plate 7 can be more efficiently transmitted to the tea oil cake through the protruding rod 28.

[0051] Embodiment three:

[0052] Reference Figure 1-Figure 3 as well as Figure 7 , which is basically the same as Example 2, and further, a specific implementation plan for refining tea oil is specifically added.

[0053] A cylindrical boss 5 is fixedly connected to the inner bottom of the extraction barrel 4, and an annular groove 6 is formed between the outer wall of the boss 5 and the inner wall of the extraction barrel 4, wherein the lower end of the column 19 extends into the annular groove 6 and is fixedly installed with a stirring rod 23, and a ring gear 27 is fixedly installed on the extraction barrel 4, and a passive gear 25 meshing with the ring gear 27 is fixedly installed on the outer wall of the column 19.

[0054] Specifically, after the pressing plate 7 extracts the tea oil, the tea oil will remain in the annular groove 6 at the bottom of the extraction barrel 4. At this time, a diluted acid solution is added to the annular groove 6, so that the rotating extraction barrel 4 will drive the stored tea oil to rotate synchronously. At this time, the column 19 inserted in the annular groove 6 can stir the tea oil to make the diluted acid solution and the extracted tea oil fully mixed, so that the degumming process of the tea oil can be quickly completed to improve the quality of the tea oil. When the sliding column 14 slides over the column 19, the column 19 will also vibrate, thereby improving the effect of stirring the tea oil.

[0055] When the extraction barrel 4 rotates, the extraction barrel 4 will drive the annular gear 27 to rotate, the annular gear 27 will drive the passive gear 25 to rotate, the passive gear 25 will drive the column 19 to rotate, and the column 19 will drive the stirring rod 23 to stir the tea oil in the annular groove 6, so that the tea oil can be degummed more efficiently, further improving the final quality of the tea oil, and when the column 19 vibrates, the column 19 will also drive the stirring rod 23 to vibrate, and the stirring rod 23 can further improve the efficiency of stirring the tea oil.

[0056] A water tank 32 for storing acid solution is fixedly installed on the top of the above-mentioned top frame 2, and a feed port 30 is opened on the top of the water tank 32.

A water outlet 31 connected to the inner tube 26 is provided on the stirring rod 23.

[0057] Specifically, when it is necessary to add diluted acid solution to the tea oil, the valve in the inner tube 26 is opened, and the solution in the water tank 32 will flow into the inner tube 26, and finally be discharged from the water outlet 31 into the annular groove 6, thereby automatically, efficiently and evenly completing the addition of the acid solution. Since the water outlet 31 is arranged on the stirring rod 23, the stirring stirring rod 23 will cause the acid solution in the water outlet 31 to be subjected to centrifugal force to improve the efficiency of the acid solution discharge.

[0058] Embodiment 4:

[0059] Reference Figure 1-Figure 2 as well as Figure 8 , which is basically the same as Example 3, and further, a specific implementation plan for filtering tea oil is specifically added.

[0060] The outer wall of the lower end of the above-mentioned extraction barrel 4 is fixedly connected to an annular box 21, the inner wall of the annular groove 6 is provided with an inner hole 24 extending into the annular box 21, the lower end of the annular box 21 is fixedly connected to a discharge pipe 33, and valves are fixedly installed in the inner hole 24 and the discharge pipe 33; the upper end of the annular box 21 is provided with a mounting groove 29, and the mounting groove 29 is plugged with a filter plate 22 extending to the top of the annular box 21, and the filter plate 22 is used to filter out impurities in the tea oil.

Finally, the discharge pipe 33 on the outer wall of the annular box 21 is opened to discharge the refined tea oil.

[0062] An edible oil extraction process, the operating steps are as follows:

[0063] Step 1: placing tea oil cakes in the gap between multiple stacked pressing plates 7;

[0064] Step 2: Use the lifting device 8 to drive the pressing block 9 to press on the top pressing plate 7;

[0065] Step 3: Make the extraction barrel 4 drive the pressing plate 7 and the tea oil cake to rotate;

[0066] Step 4: causing the rotating pressing plate 7 to generate continuous vibration;

[0067] Step 5: Mixing tea oil with the diluted acid solution;

[0068] Step 6: Filter out impurities in tea oil.

[0069] When the edible oil extraction equipment is in use, the tea oil cake is placed in the gap between multiple stacked pressure plates 7, and then the pressure block 9 is driven by the lifting device 8 to press on the top pressure plate 7.

The tea oil on the pressure plate 7 will be efficiently collected into the extraction barrel 4 under the action of centrifugal force, and the tea oil in the tea oil cake will also be more efficiently discharged, thereby improving the extraction efficiency of the tea oil.

[0070] During the rotation of the pressure plate 7, the pressure plate 7 will drive the sliding column 14 to revolve around its axis, and the ends of the plurality of sliding columns 14 will slide over the column 19 in sequence. When the sliding column 14 is pressed against the column 19, the sliding column 14 will slide into the sliding hole 13. When it passes over the column 19, the first spring 15 will drive the sliding column 14 to slide back and forth in the sliding hole 13. Therefore, when the sliding column 14 slides over the column 19, it can slide back and forth in the sliding hole 13 and drive the knocking block 18 to slide back and forth in the sliding hole 13. When the knocking block 18 presses against the protrusion 16, the knocking block 18 will knock the protrusion 16 and be received in the sliding groove 17 under the action of the top pressure. When passing the protrusion 16, the second spring 20 will drive the knocking block 18 to slide in the opposite direction and reset, so that the reciprocating sliding column 14 will also drive the knocking block 18 to repeatedly knock the protrusion 16, so that the protrusion 16 drives the pressing plate 7 to vibrate, and the pressing plate 7 will transmit the vibration to the tea oil cake, so that the tea oil in the tea oil cake can be discharged more efficiently, so as to significantly improve the extraction efficiency of the tea oil, and after multiple knocks, the protrusion 16 will generate heat under the action of friction, so that the pressing plate 7 can generate heat, and the generated heat can heat and keep the tea oil cake warm, so that the tea oil cake is not easy to cool down quickly, so as to ensure the oil output of the tea oil cake.

[0071] After the pressing plate 7 extracts the tea oil, the tea oil will remain in the annular groove 6 at the bottom of the extraction barrel 4. At this time, a diluted acid solution is added to the annular groove 6, so that the rotating extraction barrel 4 will drive the stored tea oil to rotate synchronously. At this time, the column 19 inserted in the annular groove 6 can stir the tea oil to make the diluted acid solution and the extracted tea oil fully mixed, so that the degumming process of the tea oil can be quickly completed to improve the quality of the tea oil. When the sliding column 14 slides over the column 19, the column 19 will also vibrate, thereby improving the effect of stirring the tea oil.

[0072] When the extraction barrel 4 rotates, the extraction barrel 4 will drive the annular gear 27 to rotate, the annular gear 27 will drive the passive gear 25 to rotate, the passive gear 25 will drive the column 19 to rotate, and the column 19 will drive the stirring rod 23 to stir the tea oil in the annular groove 6, so that the tea oil can be degummed more efficiently, further improving the final quality of the tea oil, and when the column 19 vibrates, the column 19 will also drive the stirring rod 23 to vibrate, and the stirring rod 23 can further improve the efficiency of stirring the tea oil.
