Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable oil processing, in particular to a filtering device for deodorizing vegetable oil. Background Art

[0002] Deodorization of vegetable oils is crucial in food processing. Its primary purpose is to remove odorous components from the oils to enhance their flavor and market acceptance. Sources of odor include raw material factors, oxidation reactions, and impurities remaining during processing. Common deodorization technologies include steam deodorization, activated carbon adsorption, and membrane separation. Filtration devices play a key role in these technologies, not only removing solid impurities from the oils but also assisting in deodorization and improving deodorization efficiency. With increasing awareness of food safety, vegetable oil deodorization technology is also continuously advancing. In the future, through the development of new materials, process optimization, and the application of green technologies, deodorization effects can be further improved, energy consumption can be reduced, and market demand can be met.

[0003] A search revealed an existing patent (publication number: CN217939301U) that discloses an energy-saving deodorization tower for edible vegetable oil, relating to the field of vegetable oil processing technology. This energy-saving deodorization tower comprises a deodorization tower body, the top of which is fixedly connected to a connecting pipe that communicates with the interior of the deodorization tower body. The connecting pipe has a mounting groove formed on its outer surface, and a mounting plate is slidably connected to the interior of the mounting groove. The mounting plate is bolted to the interior of the mounting groove. This energy-saving deodorization tower uses a brush to clean impurities attached to the top of the filter screen, reducing the risk of impurities clinging to the filter screen for a long time, which can cause clogging and affect the speed at which vegetable oil passes through the filter screen, thereby hindering the deodorization process. This ensures the filtration quality of the vegetable oil and reduces the power required by the deodorization tower body to deodorize the vegetable oil, making the device more energy-efficient.

[0004] However, in the actual use of the above solution, it is necessary to use a motor to drive a brush using a worm gear and a worm to clean the filter. However, the motor drive system consumes a certain amount of electricity during operation, especially under a large load, which may lead to energy waste. The motor and mechanical movement may generate noise, affecting the working environment, especially in places with high environmental requirements such as food processing plants. Regular maintenance and inspection of the motor and its transmission system may increase operating costs, especially when used frequently.

[0005] To this end, the utility model provides a filtering device for deodorizing vegetable oil. Utility Model Content

[0026] A second three-way pipe 14 is fixedly connected to the right side of the filter tank 3, and the second three-way pipe 14 is fixed through the filter tank 3. The top of the second three-way pipe 14 is fixedly connected to a second control valve 21, and the second control valve 21 is fixed through the second three-way pipe 14.

Then, when the vegetable oil passes through the impeller 33, the impeller 33 is driven to rotate.

The impeller 33 and the rotating blade 35 cooperate with each other to drive the vegetable oil to rotate, thereby causing the vegetable oil to rotate, thereby increasing the contact time between the vegetable oil and the filter screen 38 and improving the filtration efficiency. Then, the cleaning blade 37 is used to clean the filter screen 38. 7 rotates inside the filter 38, thereby cleaning the inner wall of the filter 38. When the filter 38 needs to be backflushed and cleaned and impurities need to be discharged, it is only necessary to close the second control valve 21 and the fourth control valve 23 and open the first control valve 2 and the third control valve 22, so that the vegetable oil enters the filter tank 3 through the second connecting pipe 12, the first control valve 2, and the first three-way pipe 13, and the vegetable oil moves from the left side of the filter 38 to the right side, thereby squeezing out impurities attached to the right side of the filter hole of the filter 38. At the same time, the vegetable oil carrying impurities is discharged through the second three-way pipe 14, the third control valve 22, and the first oil outlet pipe 15, thereby avoiding contamination of the vegetable oil.
