[0001] This utility model relates to the field of decolorization and deodorization devices, and in particular to a decolorization and deodorization device for tea oil refining and processing. Background Technology

[0002] Camellia oil is a high-quality vegetable oil. Unprocessed camellia oil contains natural pigments and oxidation products with off-odors, which affect its appearance and flavor. Therefore, during the refining process of camellia oil, it is necessary to decolorize and deodorize it to improve its appearance and flavor and extend its shelf life.

[0003] In existing technologies, the traditional tea oil refining process has low efficiency in decolorization and deodorization, short contact time between the oil and the adsorbent material, and insufficient contact area, making it difficult to completely remove pigments and odor substances from the tea oil, thus affecting the quality of the tea oil.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown in the figure, this utility model provides a decolorizing and deodorizing device for tea oil refining, including an oil storage tank 1, an activated carbon adsorption plate 2, a circulating water pump 3, an oil outlet pipe rack 4, a first electric valve 51, a second electric valve 52, and an oil discharge pipe assembly 6; the top of the oil storage tank 1 is provided with an oil inlet pipe 10 connected to it, the oil inlet pipe 10 is used to transport the tea oil to be decolorized and deodorized into the oil storage tank 1, the activated carbon adsorption plate 2 is provided at the bottom of the oil storage tank 1, the activated carbon adsorption plate 2 is used to decolorize and deodorize the tea oil in the oil storage tank 1, and the bottom of the oil storage tank 1 is provided with a first pipe 11, the first pipe 11 is connected to the liquid inlet end of the circulating water pump 3, the circulating water pump The liquid outlet of 3 is connected to the oil outlet frame 4 through the second pipe 12. The oil outlet frame 4 is located in the oil storage tank 1 above the activated carbon adsorption plate 2. The activated carbon adsorption plate 2 is located at the bottom of the oil storage tank 1. It can remove pigments and odors from the oil by adsorption and concentrate the oil at the bottom of the activated carbon adsorption plate 2. The first pipe 11 at the bottom of the oil storage tank 1 is connected to the circulating water pump 3. The oil that has undergone one decolorization and deodorization treatment can be re-extracted and transported to the upper oil outlet frame 4 by the action of the circulating water pump 3, thereby increasing the contact time and frequency between the oil and the activated carbon adsorption plate 2, improving the removal rate of pigments and odors, and effectively improving the refining effect of tea oil.

[0029] like Figure 1 and Figure 3As shown, the oil outlet pipe rack 4 includes a manifold 41 and a branch pipe 42. The manifold 41 is connected to the second pipe 12 via a flange 43. Multiple branch pipes 42 are respectively connected to the manifold 41 and are equidistantly arranged along the circumference of the manifold 41. Each branch pipe 42 has an oil outlet hole 420 along its extension direction. The oil drain pipe group 6 is connected to the second pipe 12. The oil drain pipe group 6 is used to discharge tea oil that has been decolorized and deodorized. The first electric valve 51 is installed on the second pipe 12, and the second electric valve 52 is installed on the oil drain pipe group 6. Multiple branch pipes 42 are equidistantly arranged along the circumference of the manifold 41. This arrangement allows the oil to be evenly sprayed onto the activated carbon adsorption plate 2 below through the oil outlet 420, thereby improving the contact efficiency between the oil and the activated carbon adsorption plate 2 and enhancing the decolorization and deodorization effect. The first electric valve 51 and the second electric valve 52 allow for flexible adjustment of the oil flow path, enabling switching between oil circulation decolorization and deodorization treatment and oil discharge. Specifically, when oil circulation decolorization and deodorization adsorption is required, the second electric valve 52 is closed and the first electric valve 51 is opened, thereby achieving oil circulation and multiple adsorption treatments to enhance the decolorization and deodorization effect. When the adsorption treatment is completed and the decolorized and deodorized oil needs to be discharged, the first electric valve 51 is closed and the second electric valve 52 is opened. At this time, the oil flows out through the oil drain pipe group 6 to complete the discharge process. This allows for quick switching of the device's operating mode, simplifies the operation process, and improves the system's operating efficiency and automation level.

[0030] like Figure 1 As shown, the system further includes a solvent delivery pipe 7, which is connected to the oil storage tank 1. The solvent delivery pipe 7 is used to deliver an ethanol solution into the oil storage tank 1. Ethanol can dissolve some of the pigments and odor molecules in the tea oil, reducing the difficulty of adsorbing these impurities. This makes it easier for pigments and odor substances to detach from the oil and be adsorbed. Since the boiling point of the ethanol solution is low, residual ethanol in the oil can be removed by heating or vacuum removal in subsequent processing to ensure the purity of the tea oil.

[0031] like Figure 3 As shown, the manifold 41 is further provided with multiple threaded holes (not shown) along the circumferential direction. The diverter 42 is connected to the threaded holes by a threaded seal. This arrangement allows for easy disassembly, cleaning, replacement, or maintenance of the diverter 42, preventing the oil outlet 420 from becoming clogged and affecting operating efficiency.

[0032] like Figure 1As shown, the oil drain pipe assembly 6 further includes an oil drain main pipe 61 and an oil drain branch pipe 62. The oil drain branch pipe 62 is connected to the second pipe 12 through the oil drain main pipe 61. The oil drain branch pipe 62 is provided with butterfly valves 63 at both ends. This arrangement makes it easy to adjust the opening and closing state of the butterfly valves 63 at both ends of the oil drain branch pipe 62 according to the oil discharge path.

[0033] like Figure 1 As shown, it further includes a base 13, which is supported and connected to the oil storage tank 1 by a support foot 14. A pipe support 15 is provided on the base 13, and the top of the pipe support 15 is connected to the oil drain branch pipe 62. In this way, the overall structural installation stability can be improved.

[0034] like Figure 1 As shown, the top of the oil storage tank 1 is provided with a tank cover 16, which is detachably connected to the oil storage tank 1. The tank cover 16 is provided with a lifting lug structure 161 for easy lifting and disassembly. The side wall of the oil storage tank 1 is provided with an inspection and observation port 17. This arrangement facilitates the daily maintenance, repair and replacement of internal parts of the equipment.

[0035] The above-described 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 do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
