[0002] Camellia oil is obtained from the seeds of Camellia oleifera Abel, a plant of the Theaceae family. Camellia oil also contains various active substances such as tea polysaccharides, camellia saponins, flavonoids, tea polyphenols, vitamins, and phytosterols. Regular consumption has the effects of reducing cholesterol, increasing high-density lipoprotein, reducing low-density lipoprotein, lowering blood lipids, preventing cardiovascular and cerebrovascular diseases, enhancing immunity, anti-radiation, scavenging free radicals, and preventing tumors. The basic technological process of pressing camellia oil is to sequentially process camellia seeds through crushing, drying, steaming and frying, pressing, and filtering to obtain pressed oil. Currently, the existing camellia oil pressing equipment all presses camellia oil by means of screw feeding and extrusion, and the pressing equipment uses a single screw for feeding operation. The temperature for cold pressing camellia seeds by the screw operation cannot exceed 60 degrees Celsius. During the cold pressing process, it is impossible to control in real time the additional temperature generated when the screw rod contacts the camellia seeds. The temperature control systems in the prior art are too expensive and not applicable to all merchants. Summary of the Invention

[0006] Preferably, a slide bar is rotatably connected through the inner wall plate body on one side of the air outlet plate. Both ends of the slide bar are movably sleeved with the inner walls at both ends of the groove plate. A plate plug is snap-connected through the top side wall of the groove plate, and a hopper for containing diluted saltpeter is also fixedly connected through the top side wall of the groove plate.

[0007] Preferably, L-shaped plate frames are fixedly connected to the outer walls at the bottoms of both groove plates, and the bottom plate bodies of the two L-shaped plate frames are respectively fixedly connected to one outer wall of a cold press and an oil guide hopper plate.

[0008] Preferably, a rotating handle is fixedly connected to the other end of the rotating rod. A rocking plate is slidably attached to the outer wall at the other end of the rotating handle. An arc-shaped groove is formed through the plate body of the rocking plate, and the inner wall of the arc-shaped groove is slidably attached to the handle rod of the rotating handle.

[0009] Preferably, a T-shaped rod is fixedly connected through one side plate body of the rocking plate. A connecting plate is movably sleeved on the rod of the T-shaped rod, and one end plate body of the connecting plate is fixedly connected to the outer wall of the groove plate.

[0010] Preferably, a rotating shaft is fixedly connected through the other side plate body of the rocking plate. A sleeve is movably sleeved on the rotating shaft, and one outer wall of the sleeve is fixedly connected to one outer wall of the air outlet plate.

[0011] Preferably, a cam is fixedly connected to the rod of the rotating rod. A T-shaped arc angle plate is intermittently slidably attached to the cam, and the T-shaped arc angle plate is slidably connected through the plate body of the groove plate.

The swing of the air outlet plate moves with the slide bar as the pivot point, and also squeezes the folding curtains installed at the upper and lower ends back and forth. The passively continuously swinging air outlet plate generates air flow, and since the air outlet plate faces the cold press, the generated air flow will directly contact the cold press to provide auxiliary cooling during its cold pressing process. In the present invention, the pushed T-shaped arc angle plate synchronously drives the connected material blocking plate, causing it to separate from the bottom end of the hopper, and it is impossible to completely block the bottom of the hopper. Therefore, a small amount of diluted nitre placed in the hopper will be discharged, and it will mix with some water bodies placed in the trough plate. The nitre begins to dissolve and absorbs a large amount of heat, causing the water temperature to drop rapidly. As a result, cold air will be generated inside the trough plate, and during the swinging process of the air outlet plate, the gas will automatically diffuse out of the air outlet plate and also contact the cold press, cooling its exterior, so that the internal temperature does not rise significantly and does not exceed sixty degrees.

DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Such as Figures 1 to 7As shown in the figure, the present invention provides a low-temperature cold pressing device for pure tea oil, which includes a cold press 1. A guide oil hopper plate 11 is fixedly connected to the cold press 1. A storage oil plate box 12 is arranged below the guide oil hopper plate 11. A filter screen plate 13 is attached to the inner and outer walls of the storage oil plate box 12 near the top. A motor 14 is fixedly connected to the outer wall of one end plate of the cold press 1. A spiral pressing rod 15 is fixedly connected to the rotating shaft of the motor 14. The rod body of the spiral pressing rod 15 is movably sleeved between the rod body of the spiral pressing rod 15 and the cold press 1. A low-temperature part 2 is also arranged on the rod body of the spiral pressing rod 15. The low-temperature part 2 includes two synchronous belts 21 fixedly connected to the rod body of the spiral pressing rod 15. The other sides of the two synchronous belts 21 are fixedly connected with a rotating rod 22 respectively. Cooling structures are arranged on the rod bodies of the two rotating rods 22, and reciprocating swing structures are also arranged on the other ends of the rod bodies of the two rotating rods 22.

[0019] Adopting the above scheme: When starting the motor 14 in the prior art to drive the spiral pressing rod 15 to cold press the tea seeds in the cold press 1, the cold-pressed tea oil will naturally fall onto the guide oil hopper plate 11. The oil body will be uniformly introduced into the storage oil plate box 12 through the inclination of the guide oil hopper plate 11. And the pure tea oil entering the storage oil plate box 12 will be filtered through the arranged filter screen plate 13 to ensure the quality of the oil body. And when the spiral pressing rod 15 rotates passively, it will also drive the synchronous belt 21 in the low-temperature part 2 to rotate.

[0020] Each of the two cooling structures respectively includes two sleeve rods 23 movably sleeved on the rotating rod 22. A groove plate 24 is jointly fixedly connected to the rod bodies of the two sleeve rods 23. An air outlet plate 26 is arranged in the inner wall of the groove plate 24. Folding curtains 27 are fixedly connected to the outer walls of the upper and lower ends of the air outlet plate 26. The other ends of the two folding curtains 27 are respectively fixedly connected to the inner walls of the upper and lower ends of the groove plate 24. A sliding rod 25 is rotatably connected through the inner wall plate body of one side of the air outlet plate 26. The two ends of the rod body of the sliding rod 25 are movably sleeved with the inner walls of the two ends of the groove plate 24. A plate plug 29 is through-connected and clamped on the top side wall of the groove plate 24. And a hopper 230 for containing diluted nitre is also fixedly connected through the top side wall of the groove plate 24. L-shaped plate frames 28 are fixedly connected to the outer walls of the bottoms of the two groove plates 24. And the bottom plate bodies of the two L-shaped plate frames 28 are respectively fixedly connected to one end outer walls of the cold press 1 and the guide oil hopper plate 11.

[0021] Adopting the above - mentioned solution: The swing of the air - outlet plate 26 will take the slide bar 25 as the pivot point for movement, and it will also squeeze the folding curtain 27 installed at the upper and lower ends back and forth. The passively continuously swinging air - outlet plate 26 will generate air flow. Since the air - outlet plate 26 faces the cold press 1, the generated air flow will directly contact the cold press 1, providing auxiliary cooling during its cold - pressing process, avoiding the generation of additional heat and temperature between the screw press rods 15 during the cold - pressing of rapeseed. And when the diluted nitre placed in the hopper 230 is passively fed in small amounts, it will mix with some water bodies placed in the trough plate 24. The nitre starts to dissolve and absorbs a large amount of heat, causing the water temperature to drop rapidly. Thus, cold air will be generated inside the trough plate 24. And during the swinging process of the air - outlet plate 26, the gas automatically diffuses out from the air - outlet plate 26 and also contacts the cold press 1, cooling its exterior, so that the internal temperature does not rise significantly and does not exceed sixty degrees.

[0022] At the other end of the rod body of the rotating rod 22, a rotating handle 231 is fixedly connected. On the outer wall of the other end of the rotating handle 231, a rocking plate 232 is slidably connected in a fitting manner. An arc - length groove 233 is penetrated through the plate body of the rocking plate 232, and the inner wall of the arc - length groove 233 is slidably connected in a fitting manner with the handle rod of the rotating handle 231. A T - shaped rod 234 is fixedly connected through one side plate body of the rocking plate 232. A connecting plate 235 is movably sleeved on the rod body of the T - shaped rod 234. One end plate body of the connecting plate 235 is fixedly connected to the outer wall of the plate body of the trough plate 24. A rotating shaft 236 is fixedly connected through the other side plate body of the rocking plate 232. A sleeve 237 is movably sleeved on the rotating shaft 236. One end outer wall of the sleeve 237 is fixedly connected to one end outer wall of the air - outlet plate 26.

[0023] Adopting the above - mentioned solution: When the synchronous belt 21 is passively driven to rotate, it will drive the rotating rod 22 to rotate under the limitation of the sleeve rod 23. The rotation of the rotating rod 22 will synchronously drive the fixedly installed rotating handle 231 to rotate. Thus, the passively rotating rotating handle 231 will rotate and slide in the arc - length groove 233 of the rocking plate 232, and then can drive the rocking plate 232 to swing reciprocally with the T - shaped rod 234 as the pivot point, thereby driving the air - outlet plate 26 connected in a matching manner by the rotating shaft 236 and the sleeve 237 to swing synchronously.

[0024] A cam 238 is fixedly connected to the rod body of the rotating rod 22. A T - shaped arc - angle plate 239 is intermittently slidably connected to the cam 238. The T - shaped arc - angle plate 239 is slidably connected through the plate body of the trough plate 24. Elastic members 240 are fixedly connected to both side plate bodies of the T - shaped arc - angle plate 239, and the other ends of the two elastic members 240 are both fixedly connected to the outer wall of the plate body of the trough plate 24. And the two elastic members 240 are specifically composed of springs. A blanking - blocking plate 241 is fixedly connected to the other end plate body of the T - shaped arc - angle plate 239. The top outer wall of the blanking - blocking plate 241 can be intermittently in contact connection with the bottom end of the hopper 230.

[0025] Adopting the above solution: when the rotating rod 22 rotates, it will also drive the cam 238 to rotate. The rotation of the cam 238 will intermittently contact and press against the T-shaped arc angle plate 239 on the plate body of the groove plate 24, causing its plate body to be forced to retract into the groove plate 24, thereby squeezing the elastic member 240 installed between the two. The elastic member 240 deforms under force, and the installation of the elastic member 240 can facilitate the automatic reset of the T-shaped arc angle plate 239 when it is not under force, facilitating the next repeated movement. The pushed T-shaped arc angle plate 239 will also synchronously drive the connected blanking plate 241, causing it to separate from the bottom end of the hopper 230 and unable to completely block its bottom.

[0026] It should be added that when the folding curtain 27 is passively folded up and down, the two side curtain bodies will be limited and slide on the inner wall of the corresponding plate body of the groove plate 24, thereby preventing the mixed water body in the groove plate 24 from leaking laterally. Moreover, when the folding curtain 27 is passively folded up and down, it will also have a certain rippling effect on the mixed water body, making its mixing speed faster. The plate plug 29 installed on the groove plate 24 can be used for water replenishment and pumping, while the hopper 230 is convenient for subsequent feeding.

[0027] The working principle and usage process of the present invention: when starting the motor 14 in the prior art to drive the screw pressing rod 15 to cold press the tea seeds in the cold press 1, the cold-pressed tea oil will naturally fall onto the oil guiding hopper plate 11. The inclined oil guiding hopper plate 11 will uniformly guide the oil body into the oil storage plate box 12. The pure tea oil entering the oil storage plate box 12 will be filtered through the set filter screen plate 13 to ensure the quality of the oil body. When the screw pressing rod 15 rotates passively, it will also drive the synchronous belt 21 in the low-temperature part 2 to rotate, thereby driving the rotating rod 22 to rotate under the limit of the sleeve rod 23. The rotation of the rotating rod 22 will synchronously drive the fixedly installed rotating handle 231 to rotate. Thus, the passively rotating rotating handle 231 will rotate and slide in the arc-shaped groove 233 of the rocker plate 232, and then can drive the rocker plate 232 to swing reciprocally with the T-shaped rod 234 as the pivot point, thereby driving the air outlet plate 26 connected by the matching of the rotating shaft 236 and the sleeve 237 to swing synchronously. The swing of the air outlet plate 26 will move with the sliding rod 25 as the pivot point, and will also squeeze the folding curtains 27 installed at the upper and lower ends back and forth. The continuously swinging air outlet plate 26 passively will generate air flow. Since the air outlet plate 26 faces the cold press 1, the generated air flow will directly contact the cold press 1, providing auxiliary cooling during its cold pressing process and preventing additional heat and temperature from being generated between the screw pressing rods 15 when cold pressing the rapeseed. Meanwhile, when the rotating rod 22 rotates, it will also drive the cam 238 to rotate. The rotation of the cam 238 will intermittently contact and press against the T-shaped arc angle plate 239 on the plate body of the groove plate 24, causing its plate body to be forced into the groove plate 24, thereby squeezing the elastic member 240 installed between the two. The elastic member 240 deforms under force, and the installation of the elastic member 240 facilitates the automatic reset of the T-shaped arc angle plate 239 when it is not under force, facilitating the next repeated movement. The pushed T-shaped arc angle plate 239 will also synchronously drive the connected blanking plate 241, causing it to separate from the bottom end of the hopper 230 and unable to completely block its bottom. Thus, a small amount of the diluted nitre placed in the hopper 230 will be fed, mixing with some water bodies placed in the groove plate 24. The nitre begins to dissolve and absorbs a large amount of heat, causing the water temperature to drop rapidly. Thus, cold air will be generated inside the groove plate 24, and during the swinging process of the air outlet plate 26, the gas will automatically diffuse out of the air outlet plate 26 and also contact the cold press 1, cooling its exterior, so that the internal temperature does not rise significantly and does not exceed sixty degrees. The above-mentioned operating mechanical structure is inexpensive, and its cost performance is much higher than the temperature control systems in the prior art. Moreover, it is directly driven by the original motor 14 on the cold press 1 to drive the low-temperature part 2 without the need to add other power sources, which can greatly reduce the production cost of the manufacturer.
