Description

Technical Field

[0001] This utility model relates to the field of cold pressing technology for camellia fruit, and more specifically, to a device for repeated cold pressing of camellia fruit. Background Technology

[0002] In the camellia fruit processing industry, cold pressing is a key process in the production of fat or oil from camellia seed raw materials. Currently, the cold pressing equipment commonly used in the industry works by using mechanical extrusion to apply pressure to process camellia seed particles in order to separate solid fibers and liquid emulsion.

[0003] However, existing cold-pressing devices have a significant technical drawback: after one cold press, a certain amount of liquid remains in the solid fibers discharged from the solid outlet. To further improve the oil extraction rate, these liquid-containing solid fibers need to be repeatedly cold-pressed. However, in existing technologies, this repeated cold-pressing operation requires manual re-feeding of the solid fibers from the solid outlet to the feeding inlet. This manual operation is labor-intensive and inefficient. Therefore, we propose an improvement: a repeated cold-pressing device for camellia fruit. Utility Model Content

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-4 A camellia fruit repeated cold pressing device includes a first support frame 2, a cold pressing mechanism 1 installed on the top of the first support frame 2, the cold pressing mechanism 1 including a screw press 101, the screw press 101 connected to a feeding hopper 102, the screw press 101 having a liquid outlet and a solid outlet, a crushing box 3 located at the solid outlet of the screw press 101 is provided on one side of the first support frame 2, the crushing box 3 is provided with a crushing structure, the bottom of the crushing box 3 is connected to a collection box 304, the collection box 304 is connected to an auger conveyor 306, the auger conveyor 306 is connected to a discharge pipe 307, and the bottom end of the discharge pipe 307 extends into the feeding hopper 102; after the solid fiber is discharged from the solid outlet of the cold pressing mechanism 1, it is crushed by the crushing structure and then transported to the feeding hopper 102 through the auger conveyor 306 and the discharge pipe 307. The solid fiber powder is automatically and repeatedly cold pressed by the cold pressing mechanism 1, eliminating the need for manual handling and feeding, thus reducing the labor intensity of workers;

[0027] The collection box 304 is transparent, such as being made of acrylic material, or has an observation window to facilitate observation of the amount of solid fibers inside the collection box 304;

[0028] The screw press 101 and the auger conveyor 306 are both existing components, and their specific structures and principles are existing technologies, which will not be described in detail in this application.

[0029] Furthermore, the crushing structure includes two crushing rollers 301 mounted in the crushing chamber 3 via bearings. One end of each crushing roller 301 extends to the outside of the crushing chamber 3 and is connected to a gear 302. The two gears 302 mesh with each other. A second motor 303 is connected to the side of the crushing chamber 3 away from the gears 302. The second motor 303 is connected to one of the crushing rollers 301. The second motor 303 and the two gears 302 cooperate to make the two crushing rollers 301 rotate. The two crushing rollers 301 can crush the solid fibers squeezed by the cold pressing mechanism 1 so that they can be conveyed by the auger conveyor 306.

[0030] Furthermore, a second support frame 305 is provided at the bottom of the collection box 304, which is used to support the collection box 304.

[0031] Furthermore, the bottom of the collection box 304 is inclined, and the auger conveyor 306 is connected at the lowest point of the inclination, so that the solid fibers can move to the auger conveyor 306 after being crushed, thereby facilitating the conveying of the crushed solid fibers by the auger conveyor 306.

[0032] Furthermore, a baffle 308 is connected to the top of the crushing box 3, and a guide plate 4 is installed on the top cold pressing mechanism 1 of the first support frame 2. The guide plate 4 is located at the solid discharge outlet of the screw press 101 and above the baffle 308. The solid fibers discharged from the solid discharge outlet of the cold pressing mechanism 1 can be guided to the baffle 308 through the guide plate 4. Since the guide plate 4 is above the baffle 308, when there is no need to press again after repeated pressing, a collection container, such as a material tray, can be placed on the top of the baffle 308 to receive the solid fibers, so that the solid fibers do not need to enter the baffle 308.

[0033] Furthermore, the cold pressing mechanism 1 also includes a driving component for driving the screw press 101 to operate. The driving component includes a first motor 104 installed inside the first support frame 2. The output shaft of the first motor 104 is connected to a drive wheel 105. The screw press 101 is connected to a driven wheel 106. A transmission belt 107 is connected between the driven wheel 106 and the drive wheel 105. Through the cooperation of the transmission belt 107, the driven wheel 106 and the drive wheel 105, the power of the first motor 104 can be transmitted to the screw press 101, thereby driving the screw press 101 to operate.

[0034] Furthermore, a protective cover 103 is installed on the side of the first support frame 2. The driven wheel 106, the transmission belt 107 and the driving wheel 105 are all located inside the protective cover 103. The protective cover 103 is installed on the first support frame 2 by bolts. The protective cover 103 can protect the driven wheel 106, the transmission belt 107 and the driving wheel 105.

[0035] Furthermore, the cold pressing mechanism 1 also includes a liquid collection tank 108, which is mounted on the first support frame 2, and a liquid discharge pipe 109 is connected to the bottom of the liquid collection tank 108. The liquid collection tank 108 is located above the liquid discharge port of the screw press 101. The liquid collection tank 108 is used to collect the liquid discharged during the cold pressing process of the screw press 101, while the liquid discharge pipe 109 is used to discharge the liquid collected by the liquid collection tank 108.

[0036] Furthermore, a support plate 5 is fixedly installed on the side of the first support frame 2 near the auger conveyor 306, and a groove is provided on the support plate 5. The inner wall of the groove is in contact with the outer surface of the auger conveyor 306. The support plate 5 can support the auger conveyor 306 to improve the stability of the auger conveyor 306.

[0037] The usage process of the camellia fruit repeated cold-pressing device provided by this utility model is as follows:

[0038] Crushed camellia seed particles are fed into the feed hopper 102 and enter the screw press 101. The screw press 101 performs cold pressing, and the cold-pressed liquid flows into the liquid collection tank 108 through the liquid outlet. The solid fibers are discharged into the guide plate 4 through the solid outlet and enter the crushing box 3 through the enclosure 308. After being crushed by the crushing roller 301, the solid fibers are collected in the collection box 304. The solid fibers are not conveyed at first. When a certain amount of camellia seed particles have been cold-pressed or when the amount of solid fibers in the collection box 304 reaches its maximum, the addition of camellia seed particles is stopped, and the auger conveyor 306 is started. The auger conveyor 306 conveys the crushed solid fibers in the collection box 304 through the discharge pipe 307 to the feed hopper 102, and then from the feed hopper 102 into the screw press 101 for repeated cold pressing.
