Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vegetable oil processing technology, specifically relating to a vegetable oil decolorization device. Background Technology
[0002] In the refining process of vegetable oils, decolorization is a crucial step, mainly involving the removal of pigments and impurities through adsorbents (such as activated clay and activated carbon). Traditional decolorization devices often employ a single stirring adsorption method, which suffers from insufficient stirring and incomplete decolorization. Some devices, such as the decolorization device for vegetable oil production with publication number CN214654733U, use two-stage adsorption and add a filtration mechanism at the bottom of the stirring tank. However, the residue filtered out is difficult to handle and cannot be cleaned flexibly. Utility Model Content
[0003] The purpose of this invention is to provide a vegetable oil decolorization device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a vegetable oil decolorization device, comprising a stirring tank, the stirring tank being mounted on a support, a tank cover being mounted on the stirring tank, a stirring motor being mounted on the tank cover, a stirring rod being mounted inside the stirring tank, the stirring motor being driven and connected to the stirring rod, a steam pipe being mounted at the bottom of the stirring tank, several branch pipes being mounted on the steam pipe, steam nozzles being mounted on the branch pipes, a filter box being mounted on the lower side of the stirring tank, a detachable box being mounted in the middle of the filter box, and a perforated plate being mounted at the bottom of the detachable box.
[0005] Preferably, the bottom of the filter box is provided with a bent pipe.
[0006] Preferably, a porous support plate is provided on the lower side of the detachable box and inside the filter box.
[0007] Preferably, a feed pipe is provided on the barrel lid.
[0008] Preferably, the steam pipe is circular and has a steam inlet pipe connected to it.
[0009] Preferably, a square frame is provided in the middle of the filter box, and an opening is provided on one side of the square frame. The detachable box body is inserted into the filter box along the opening.
[0010] Preferably, a support rod is rotatably provided on the lower side of the square frame, and rollers are provided on the support rod.
[0011] Preferably, a valve is provided at the top of the filter box.
[0012] The technical effects and advantages of this utility model are as follows: 1. The adsorbent and vegetable oil are fully contacted by steam-assisted mechanical stirring in the mixing tank, which improves the pigment adsorption efficiency.
[0013] The filter box is equipped with a removable box filled with activated carbon, which can achieve deep decolorization while intercepting residual adsorbent, and significantly improve the decolorization purity.
[0014] The branch nozzles of the steam pipe achieve uniform heating, and when combined with the electric heater, they prevent oil oxidation caused by localized overheating, resulting in better temperature control.
[0015] The detachable box is assisted by a support rod with rollers for easy assembly and disassembly, saving manpower. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0021] This utility model provides, for example Figure 1-3The illustrated vegetable oil decolorization device includes a mixing tank 1, which is mounted on a support 9. A tank cover 2 is mounted on the mixing tank 1, and a feed pipe 4 is mounted on the tank cover 2. A stirring motor 3 is mounted on the tank cover 2. A stirring rod 5 is installed inside the mixing tank 1, and the stirring motor 3 is connected to the stirring rod 5. A steam pipe 6, circular in shape, is connected to a steam inlet pipe. Several branch pipes 7 are mounted on the steam pipe 6, and steam nozzles are mounted on the branch pipes 7. The steam inlet pipe is connected to external steam. After entering, the steam flows through the steam pipe 6 into each branch pipe 7 and is ejected from the steam nozzles on the branch pipes 7. This process heats and controls the temperature of the vegetable oil inside. The steam ejection also provides pneumatic stirring of the vegetable oil, which, combined with the stirring rod 5, ensures more thorough stirring. An electric heater is also installed inside the tank.
[0022] As an embodiment of this application, an additional activated carbon filter is added. A filter box 10 is provided on the lower side of the stirring tank 1, and a valve 8 is provided on the upper part of the filter box 10. After stirring, the valve 8 is opened, and the vegetable oil enters the filter box 10. A square frame is provided in the middle of the filter box 10, and an opening is provided on one side of the square frame. A detachable box 13 is inserted into the filter box 10 along the opening, and a perforated plate 14 is provided at the bottom of the detachable box 13. A porous support plate 12 is provided on the lower side of the detachable box 13 and inside the filter box 10. Activated carbon is placed inside the detachable box 13 to adsorb the passing vegetable oil and decolorize it.
[0023] Specifically, a bent pipe 11 is provided at the bottom of the filter box 10, which is used to connect the decolorized vegetable oil container.
[0024] Specifically, a support rod 15 is rotatably mounted on the lower side of the square frame, and a roller 16 is mounted on the support rod 15. When the detachable box 13 is taken out, the support rod 15 is rotated, and the support rod 15 plays a supporting role, while the roller 16 on it makes it easy to take out the detachable box 13.
[0025] During operation, the vegetable oil decolorization device first heats the oil with steam, then adds an adsorbent, such as activated clay, and stirs continuously for 30-60 minutes to allow the pigments to be fully adsorbed. Steam is continuously introduced to control the temperature; excessively high temperatures may cause oil oxidation, while excessively low temperatures reduce adsorption efficiency. After sufficient adsorption, valve 8 is opened, allowing the oil to pass through a removable box 13 containing activated carbon (or other adsorbents). The activated carbon performs secondary decolorization of the oil and filters out the adsorbent added in the stirring tank 1, resulting in better decolorization. When it is necessary to replace or dispose of the adsorbent in the removable box 13, valve 8 is closed, and the removable box 13 is removed for processing.
[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
