Description

Technical Field

[0001] The present invention relates to the technical field of production and processing equipment, and more particularly to low-temperature pressing equipment for processing oil-tea camellia seeds. Background Art

[0002] Camellia oleifera is a small evergreen tree in the family Theaceae. Its seeds are used to produce edible oil (camellia seed oil). Camellia seed oil is a pure, natural, high-end vegetable edible oil. Its main components are unsaturated fatty acids, primarily oleic and linoleic acids, accounting for up to 90% of the total. Oleic acid accounts for over 80% of the total, making it highly absorbable by the human body. Camellia seed oil is rich in antioxidants and has skin-beautifying properties. Low-temperature pressing involves pressing the oil at temperatures below 65°C, minimizing the damage to its components.

[0003] Traditional tea seed pressing equipment generally uses a hammer crusher to crush tea seeds. However, since the particle sizes of tea seeds are different, if the large and small particles are mixed and crushed for pressing, the large particles of tea seeds will not be fully crushed, while the small particles of tea seeds will be over-crushed. At this time, if the tea seeds are pressed, the small particles of tea seeds will be over-extruded and heated, while the large particles of tea seeds will not produce enough oil. For this reason, a graded reflux system is generally used. The tea seeds of different particle sizes are crushed uniformly through the crushing device. After the crushing is completed, the tea seeds are screened through a vibrating screen. When the particle size of the tea seeds meets the pressing conditions, they are squeezed out. Oil, when the particle size of camellia seeds is higher than the pressing conditions, they are crushed again, and then screened through a vibrating screen again after crushing. If the particle size meets the pressing conditions, they are pressed. If repeated crushing causes the camellia seeds particles to be lower than the pressing conditions, they need to be treated separately. However, repeated screening of camellia seeds through a vibrating screen wastes a lot of time, which greatly reduces the pressing efficiency of camellia seeds. At the same time, repeated crushing of camellia seeds will cause some camellia seeds to become too fine powder, resulting in poor fluidity during pressing and easy clogging of the oil circuit, which requires shutdown for cleaning, wasting a lot of time, and thus reducing the pressing efficiency of camellia seeds.

[0004] In view of the above situation, the present invention designs a low-temperature pressing equipment for processing camellia seeds to solve the above technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a low-temperature pressing equipment for processing camellia seeds. The device solves the problem that when the oil is squeezed out of the camellia seeds, the particles of the camellia seeds are of different sizes. When the camellia seeds are crushed, the crushed camellia seeds need to be repeatedly screened. The camellia seeds with particles higher than the pressing conditions need to be repeatedly crushed, causing some of the camellia seeds to become too fine powder, thereby clogging the oil path during the pressing process, which requires a lot of time to clear, thereby reducing the efficiency of the camellia seed pressing.

The crushing rings 551 are provided with a plurality of crushing teeth 552 for crushing camellia seeds.

[0026] Specifically, the device also includes a transmission motor 4, which is arranged on one side of the transmission shaft 512, and the output end of the transmission motor 4 is connected to the rotating shaft 41, and the other end of the rotating shaft 41 is fixedly connected to a plug 42, and the plug 42 controls the distance between the plug 42 and the rotating shaft 3 through the transmission motor 4.

[0027] Working principle and working process: before the work starts, the operator first pours the oil-tea camellia seeds that need to be squeezed into the feed hopper 13. After the oil-tea camellia seeds are poured into the feed hopper 13, the oil-tea camellia seeds that meet the conditions are filtered through the drop holes 5132 set on the dividing plate 513. Due to the sliding connection between the crushing ring 551 and the crushing roller 55, when the oil-tea camellia seeds that meet the conditions fall to the crushing roller 55, the crushing roller 55 is driven to rotate by the driving device (not shown in the figure), so that the crushing roller 55 drives the crushing ring 551 to move synchronously, and the crushing teeth 552 on the crushing ring 551 are used to crush the oil-tea camellia seeds, thereby crushing the oil-tea camellia seeds into powder that meets the squeezing conditions. The oil-tea camellia seeds that meet the conditions are crushed into powder that meets the squeezing conditions. The powder enters between the filter screen 21 and the spiral blade 31, and the driving motor 11 drives the transmission box 12 to rotate the rotating shaft 3, and at the same time cooperates with the plug 42 to squeeze the tea seeds. The squeezed tea oil is filtered through the filter screen 21 and then flows out from the discharge port 14 for collection. In order to facilitate the discharge of the pressed tea seed residue, the distance between the plug 42 and the filter screen 21 can be adjusted, and the transmission motor 4 can be used to drive the rotating shaft 41 to drive the plug 42 away from the filter screen 21. At this time, the driving motor 11 drives the rotating shaft 3 to rotate the spiral blade 31, so that the tea seed residue can be discharged through the residue discharge port, avoiding the problem of long-term retention in the sealing cylinder 2 and blockage that affects the efficiency of tea seed squeezing. In the initial state, the distance between the multiple crushing rings 551 on the crushing roller 55 can crush the tea seeds falling through the drop holes 5132 into powder that meets the pressing conditions. Since the particles of tea seeds are of different sizes, the crushing roller 55 can crush small particles of tea seeds in the initial state, while large particles of tea seeds will be retained in the arc groove 5131 provided on the dividing plate 513. When it is necessary to crush large particles of tea seeds, the control motor 511 is started, and the control motor 511 rotates to drive the transmission shaft 512 to rotate. Since the transmission shaft 512 is fixedly connected to the dividing plate 513, and the dividing plate 513 is connected to both sides of the dividing plate 513 with driving gears 521, when the transmission shaft 512 rotates, it can drive the dividing plate 513 and the driving gear 521 to rotate. The dividing plate 513 rotates to pour the large particles of tea seeds in the arc groove 5131 into the feed hopper 13, and the driving gear 521 The rotation drives the L-shaped driven rack 522 set on its side to move, and the movement of the L-shaped driven rack 522 can drive the corresponding control plate 53 to move. Since the control groove 531 on the control plate 53 cooperates with the limit column 541, and the limit column 541 is set in the moving groove 131, when the control plate 53 moves upward, the limit column 541 set at one end of the control ring 54 is squeezed by the control groove 531 and moves in the moving groove 131, so that the control ring 54 can drive the crushing ring 551 to move on the crushing roller 55, thereby increasing the gap between multiple crushing rings 551, thereby ensuring that large-particle tea seeds can be effectively crushed, avoiding the need for tea seeds with particles higher than the pressing conditions to be repeatedly crushed, causing some tea seeds to become too fine powder, thereby blocking the oil circuit during the pressing process, and taking a lot of time to clear it, thereby improving the tea seed pressing efficiency.
