Description

Technical Field

[0001] This utility model relates to the field of low-temperature extraction technology of camellia oil, specifically to a low-temperature extraction device for camellia oil. Background Technology

[0002] Camellia oil is a natural plant oil extracted from the seeds of the camellia tree. Low-temperature extraction of camellia oil is a process that extracts oil at low temperatures using physical or mild chemical methods. This process aims to preserve the natural nutrients in camellia oil to the maximum extent while avoiding oxidation or damage caused by high temperatures. Low-temperature extraction equipment is used in the low-temperature extraction of camellia oil.

[0003] In the low-temperature extraction of camellia oil, the camellia seeds are shelled, crushed into granules, and not roasted at high temperatures. The raw materials are soaked in solvent at low temperatures to dissolve the oil. The oil and solvent are separated by vacuum distillation. The solvent can be recycled. Under the soaking of the solvent, the oil in the camellia seeds is discharged. When discharged, the mixed oil carries some of the raw material, which needs to be filtered before entering the next process. The filtration process requires filtration equipment such as filter screens and filter bags.

[0004] However, currently, when filtering mixed oil for the first time, a filter screen is usually used. But as the amount of mixed oil filtered increases, the residue in the mixed oil will accumulate on the filter screen. As the residue increases, the subsequent mixed oil cannot pass through the filter screen quickly, affecting the filtration efficiency of the filter screen. To address this, we propose a low-temperature extraction device for camellia oil. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1:

[0031] Reference Figure 1-4This is the first embodiment of the present invention, which discloses a low-temperature extraction device for camellia oil, comprising:

[0032] The low-temperature extraction body 1 has an oil outlet pipe 5 on its outer side and a filter tank 6 below the oil outlet pipe 5.

[0033] The filter tank 6 is equipped with an oil drain pipe on the outside for discharging the filtered mixed oil, and a material discharge pipe at the bottom of the filter tank 6 for discharging the sediment.

[0034] The low-temperature extraction body 1 has a slag outlet 2 symmetrically distributed with the oil outlet pipe 5 on its outer side, a solution inlet 3 on its outer side, and a material inlet 4 for the entry of camellia oil material on its outer side.

[0035] The solvent is specifically food-grade n-hexane, and the internal temperature of the low-temperature extraction body 1 is controlled below 60°C throughout the entire process.

[0036] The filtration mechanism 7 includes a partition 705 fixedly connected to the inside of the filter tank 6. A fan-shaped filter screen 701 is provided on one side of the partition 705. A fan-shaped notch 708 is provided at the top of the partition 705. A guide plate 707 extending to the outside of the filter tank 6 is provided below the notch 708. A cleaning brush 704 is provided above the guide plate 707.

[0037] Specifically, a drive motor 703 is installed on the top of the filter tank 6. The drive motor 703 is fixedly connected to a transmission rod 702 through an output shaft. The other end of the transmission rod 702 passes through the top of the filter tank 6 and extends into the interior of the filter tank 6. A cleaning brush 704 is fixedly connected to the outside of the transmission rod 702.

[0038] The drive motor 703 drives the transmission rod 702 to rotate through the output shaft. The rotation of the transmission rod 702 drives the cleaning brush 704 fixed on the outside to rotate. The rotation of the cleaning brush 704 sweeps the material residue accumulated on the filter screen 701 into the notch 708, so that it enters the notch 708.

[0039] Specifically, a through groove 706 is provided on the outside of the filter tank 6, and a guide plate 707 is fixedly connected to the inside of the through groove 706 in an inclined shape.

[0040] The guide plate 707 is fixed by the through groove 706, so that the guide plate 707 can extend to the outside of the filter tank 6, discharge the slag outside the filter tank 6, and enter the extrusion process for extrusion.

[0041] Example 2:

[0042] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0043] The extrusion mechanism 8 includes a cylinder 802 located outside the filter tank 6. A pressure plate 810 is fixedly connected to the telescopic end of the cylinder 802. Oil outlet holes 803 with equal spacing are opened on the lower outer side of the guide plate 707. An oil box 809 is fixedly connected to the outer side of the filter tank 6. A return pipe 806 extending into the interior of the filter tank 6 is fixedly connected to the bottom of the oil box 809.

[0044] An internal mounting hole is provided at the bottom of the oil box 809, and the return pipe 806 is installed inside the mounting hole to facilitate the mixed oil in the oil box 809 to re-enter the filter tank 6 for the next filtration process.

[0045] Specifically, a bracket 801 is fixedly connected to the outside of the cylinder 802, and the bracket 801 is fixedly connected to the outside of the filter canister 6.

[0046] The support 801 can fix the position of the cylinder 802 to ensure the stability of the cylinder 802 during operation. The cylinder 802 pushes the pressure plate 810 to move and squeeze the material residue on the guide plate 707.

[0047] Specifically, a baffle 807 is fixedly connected to the bottom of the pressure plate 810. The outer side of the baffle 807 is in contact with the outer side of the guide plate 707. Two symmetrically distributed side plates 808 are fixedly connected to the outer side of the guide plate 707.

[0048] The baffle 807 blocks the material from the discharge point of the guide plate 707, limiting the material residue on the guide plate 707 to facilitate the subsequent squeezing by the pressure plate 810 and avoid the waste of mixed oil in the material residue. Under the action of the side plate 808, the material residue is limited from both sides of the guide plate 707 to prevent the material residue from scattering.

[0049] Specifically, a placement rack 804 is fixedly connected to the bottom of the oil box 809, and a slag box 805 is provided inside the placement rack 804.

[0050] The placement rack 804 facilitates the placement of the slag box 805 and limits the movement of the slag box 805. The slag box 805 allows for the collection of the compressed slag, facilitating subsequent unified processing.

[0051] The remaining structure is the same as that in Example 1.

[0052] The workflow of this utility model is as follows:

[0053] When extracting camellia oil raw materials at low temperature, the prepared material blank is put into the low temperature extraction body 1 through the material blank inlet, and is transported to the other side by the action of the spiral blades inside.

[0054] At the same time, the solvent used for the camellia oil raw material immersion body comes into contact with the material embryo inside the low temperature immersion body 1 from the solution inlet 3, and carries out the oil inside it, which is then transported into the filter tank 6 through the oil outlet pipe 5.

[0055] The mixed oil entering the filter tank 6 falls onto the filter screen 701. Under the action of the filter screen 701, the material residue carried in the mixed oil is filtered. The filtered mixed oil enters below the filter screen 701 and enters the next filtration process.

[0056] The drive motor 703 drives the transmission rod 702 to rotate through the output shaft. The rotation of the transmission rod 702 drives the cleaning brush 704 to rotate. The cleaning brush 704 rotates to clean the material residue accumulated on the filter screen 701, sweeping it into the inlet 708 and falling onto the guide plate 707 below, and then discharging it into the filter tank 6.

[0057] Under the action of the baffle 807, the material residue on the guide plate 707 is blocked. When it accumulates to a certain amount, the cylinder 802 pushes the pressure plate 810 to move downward, squeezing the material residue on the guide plate 707. The mixed oil carried in the material residue is discharged through the oil outlet 803 below and enters the oil box 809 below. It then enters the filter tank 6 again through the return pipe 806.

[0058] Immediately, cylinder 802 contracts, and the compressed slag enters the slag box 805 below under the action of guide plate 707, which is cleaned and replaced regularly.

[0059] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
