Description

Technical Field

[0001] This utility model relates to the field of oil pressing equipment technology, specifically a cold press for the production of extra virgin camellia oil. Background Technology

[0002] The production of camellia oil involves the process of shelling, drying, crushing, steaming, pressing, and filtering.

[0003] Most camellia oils are now produced using a hot-pressing method after dehulling, where pressing is done while the oil is being heated. However, heating during the pressing process can cause camellia oil to produce carcinogenic substances such as benzopyrene and acrylamide, affecting the quality of the oil. At the same time, heating will generate a certain amount of water vapor, increasing the complexity of subsequent oil filtration and affecting the lifespan of the oil pressing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a cold press for the production of extra virgin camellia oil, in order to solve the technical problem that substances generated during the existing heated pressing process affect oil filtration and the service life of the oil pressing equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cold press for producing extra virgin camellia oil includes a base with a support frame at the rear end. A hydraulic device is mounted on the top of the support frame, containing a hydraulic rod. A pressure plate is fixedly mounted on the bottom of the hydraulic rod. A fixed plate is located at the center of the front end of the support frame, with a mounting hole at the top front end of the fixed plate containing a pressing chamber. A second hydraulic device is located at the rear end of the top of the fixed plate, containing a second hydraulic rod. A connecting plate is fixedly mounted on the bottom of the second hydraulic rod, with a mounting groove at the bottom of the connecting plate containing a movable block. A rotating block is located at the front end of the movable block. A connecting platform is located at the front end of the fixed plate, with a second connecting platform connected to its outer side. A filter plate is fixedly connected to the rear end of the second connecting platform, with a filter screen fixedly mounted in the middle of the filter plate. A baffle is located on the top of the filter plate, and rotating holes are located on the left and right sides of the filter plate. An oil outlet hopper is fixedly mounted on the bottom of the filter plate, with an oil outlet pipe at the bottom of the oil outlet hopper. An oil tank and a collection box are placed on the top of the base.

[0007] As a preferred embodiment of this utility model, the filter screens are symmetrically distributed in the middle of the filter plate, and the lower filter screens are finer than the upper filter screens.

[0008] As a preferred embodiment of this utility model, the inner diameter of the extrusion chamber is the same as the diameter of the pressure plate, and the inner diameter of the extrusion chamber is the same as the diameter of the filter screen.

[0009] As a preferred embodiment of this utility model, the first connecting platform and the second connecting platform are movably connected by a rotating pin.

[0010] As a preferred embodiment of this utility model, the rotating block is installed inside the rotating hole.

[0011] Compared with the prior art, the cold press machine for producing extra virgin camellia oil provided by this utility model has the following beneficial effects: the equipment uses a hydraulic device to cold press the tea seeds without heating, avoiding the production of carcinogenic substances such as benzopyrene and acrylamide during the pressing process. It not only has a high oil yield, but also a good oil residue separation effect. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0021] See Figure 1-4 As shown in the figure, a cold press for producing extra virgin camellia oil according to an embodiment of the present invention includes a base 1, a support frame 101 at the rear end of the base 1, a hydraulic device 102 at the top of the support frame 101, a hydraulic rod 103 installed inside the hydraulic device 102, a pressure plate 104 fixedly installed at the bottom of the hydraulic rod 103, a fixing plate 105 at the middle of the front end of the support frame 101, a mounting hole 108 at the front end of the top of the fixing plate 105, a pressing chamber 4 installed inside the mounting hole 108, a second hydraulic device 106 at the rear end of the top of the fixing plate 105, a second hydraulic rod 107 installed inside the hydraulic device 106, and a pressure plate 107 fixed at the bottom. A connecting plate 109 is installed, with an installation groove 110 at the bottom of the connecting plate 109. A movable block 3 is installed inside the installation groove 110. A rotating block 301 is provided at the front end of the movable block 3. A connecting platform 111 is provided at the front end of the fixed plate 105. A connecting platform 204 is connected to the outside of the connecting platform 111. A filter plate 2 is fixedly connected to the rear end of the connecting platform 204. A filter screen 201 is fixedly installed in the middle of the filter plate 2. A baffle 202 is provided at the top of the filter plate 2. Rotating holes 203 are provided on the left and right sides of the filter plate 2. An oil outlet hopper 205 is fixedly installed at the bottom of the filter plate 2. An oil outlet pipe 206 is provided at the bottom of the oil outlet hopper 205. An oil tank 5 and a collection box 6 are placed on the top of the base 1.

[0022] The filter screens 201 are symmetrically distributed in the middle of the filter plate 2, and the lower filter screen 201 is finer than the upper filter screen 201. This facilitates multiple filtrations of the oil pressed from the camellia seeds, preventing any camellia seeds from passing through the filter screens 201 and entering the oil tank 5, thus damaging the quality of the camellia oil.

[0023] The inner diameter of the extrusion chamber 4 is the same as the diameter of the pressure plate 104, and the inner diameter of the extrusion chamber 4 is the same as the diameter of the filter screen 201, ensuring that all the camellia seeds in the extrusion chamber 4 can be pressed without any leakage, and at the same time ensuring that all the camellia oil can be filtered.

[0024] The connecting platform 111 and the connecting platform 204 are movably connected by a rotating pin, which allows the filter plate 2 to rotate through the center of the rotating pin.

[0025] The rotating block 301 is installed inside the rotating hole 203, connecting the hydraulic device 106 and the filter plate 2, ensuring that the filter plate 2 can rotate when the hydraulic rod 107 moves downward.

[0026] In this embodiment of the invention, camellia seeds are placed in the extrusion chamber 4. The hydraulic device 102 is activated, and the pressure plate 104 is moved downwards via the hydraulic rod 103 to apply sufficient pressure to the camellia seeds, pressing out the oil. After the camellia oil is pressed out, it flows downwards through the filter screen 201. The multiple filters 201 filter out impurities carried by the camellia oil, ensuring its quality. The pressed camellia oil flows into the oil tank 5 through the oil outlet hopper 205 and the oil outlet pipe 206. After all the camellia oil has been squeezed out, the hydraulic device 206 is activated, and the hydraulic rod 207 moves the connecting plate 109 downwards. At the same time, the filter plate 2 swings in a circular motion, moving the camellia seed residue remaining in the extrusion chamber 4 to the collection box 6 through the tilt angle of the swinging filter plate 2, thus recycling the camellia seed residue.

[0027] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
