Description

Oil filtration and sterilization system

The present invention relates to an oil filtering system, in particular to an oil filtering and sterilizing system.

Currently, businesses that sell fried foods mostly use an existing frying machine to fry the fried foods. The frying machine has a frying tank for accommodating edible oil, a discharge port connected to the frying tank, and a heating source for heating the edible oil in the frying tank.

However, frying fried foods often produces a large amount of frying dust. If not removed immediately, the quality of the cooking oil may deteriorate, causing the fried foods to smell like oil, or produce carcinogens. The method for removing fried powder is nothing more than using a long-handled colander, or using oil filter paper with chemical composition to manually fish and filter, or sprinkling oil filter powder into the frying tank to remove the fried powder. Chips settle.

However, manual fishing is inefficient and can only fish out a small amount of fried powder chips, but cannot fish out finer powder chips, which will still cause the quality of the edible oil to decline. In addition, after sprinkling the filtered oil powder, you still need to manually drain out all the cooking oil, and then clean up the precipitated fried powder chips, such as using clean water to rinse the frying tank. However, this cleaning method will increase the operating time and cost. Efficiency still needs to be improved. Moreover, when you sprinkle oil filter powder or use oil filter paper into the edible oil, you will inevitably worry about whether chemical substances will remain in the edible oil, and repeated use may have an impact on human health. Obviously, this existing oil filtering method still has room for improvement.

Therefore, the purpose of the present invention is to provide an oil filtering and sterilizing system that can overcome the above shortcomings.

Therefore, the new oil filtering and sterilizing system is suitable for filtering edible oil. The oil filtering and sterilizing system includes a frying unit, an oil filtering unit, a motor unit and a sterilizing unit. The frying unit includes a shell defining a frying tank and a discharge port connected to the frying tank, a discharge valve positioned corresponding to the discharge port and used to open or close the discharge port, and A heating source used to heat the frying tank, which is used to contain the edible oil. The oil filter unit includes an oil filter container that defines a container and is used to locate the discharge port, a small-pore filter screen that is disposed in the oil filter container and located above the container, and a filter that is disposed on the A large-pore filter is located in the oil filter container and above the small-pore filter. The container is used to accommodate the edible oil filtered through the large-pore filter and the small-pore filter. The motor unit includes a conduit connected to the container, and a motor body connected to the conduit. The motor body is used to drive the edible oil in the container to flow back into the frying tank through the conduit. The sterilization unit is used to sterilize the edible oil flowing back into the frying tank.

The function of the present invention is to filter the edible oil through the large-pore filter screen and the small-pore filter screen of the oil filter unit, and drive the edible oil in the tank to flow back through the conduit through the motor body. In the frying tank, the edible oil returned to the frying tank is finally sterilized by the sterilization unit to ensure the quality of the edible oil, allowing consumers to eat healthily, prolonging the service life of the edible oil and thereby reducing the cost of the oil. The operator's cost is reduced, and the working environment can be improved by reducing the fumes generated during frying operations.

The motor body 32 is used to drive the edible oil in the container 211 to flow back into the frying tank 111 through the conduit 31 .

The sterilization unit 4 includes a top cover 41 for shielding the frying tank 111 , and an ultraviolet lamp 42 connected to the top cover 41 and facing the frying tank 111 .

Referring to Figures 1, 2 and 5, a control method is implemented through this embodiment and a storage unit 5. The control method includes the following steps:

Step S11: Stop the heating source 13 of the frying unit 1 from heating the edible oil located in the frying tank 111. At this time, since the frying operation is completed, there is not only the remaining edible oil in the frying tank 111, but also correspondingly generated fried chips.

Step S12: Set the position of the oil filter container 21 of the oil filter unit 2 to be below the discharge port 112.

Step S13: Referring to Figures 1, 4 and 5, the discharge valve 12 of the frying unit 1 opens the discharge port 112 to allow the portion of the edible oil located in the frying tank 111 to pass through the discharge port. After the material port 112 flows into the oil filter container 21 , it first passes through the large-pore filter 23 , then passes through the small-pore filter 22 , until it flows into the tank 211 .

More precisely, after the discharge port 112 is opened by the discharge valve 12, most of the remaining edible oil can flow into the oil filter container 21 through the discharge port 112 for subsequent oil filtering operations. . At this time, a certain proportion of fried powder chips (about 20% of the total weight) will flow into the oil filter container 21 through the discharge port 112 along with most of the remaining edible oil.

Step S14: Referring to Figures 2 and 5, move the oil filter container 21 of the oil filter unit 2 away from the discharge port 112, and then position the storage unit 5 corresponding to the bottom of the discharge port 112, so as to be located at the discharge port 112. The fried powder chips in the frying tank 111 fall into the storage unit 5 through the discharge port 112 due to their own weight.

To be more precise, the fried powder chips located in the frying tank 111 account for about 80% of the total weight. Then, the fried powder chips falling into the storage unit 5 through the discharge port 112 due to their own weight account for about 70% of the total weight. In other words, the fried powder chips remaining (sticky) in the frying tank 111 account for about 10% of the total weight.

Step S15: Referring to Figures 1, 4 and 5, move the storage unit 5 away from the discharge port 112, and then position the oil filter container 21 of the oil filter unit 2 below the discharge port 112 again.

Step S16: Let the side of the conduit 31 opposite to the container 211 communicate with the frying tank 111, and then make the motor body 32 of the motor unit 3 exert force on the conduit 31 to drive the frying pan located in the container 211. The edible oil flows back into the frying tank 111 through the conduit 31 .

Step S17: The edible oil flowing back into the frying tank 111 washes the fried powder chips (about 10% of the total weight) remaining in the frying tank 111, thereby producing a flushing and cleaning effect. After the flushing is completed, the edible oil and remaining fried powder that flow back into the frying tank 111 flow into the oil filter container 21 through the discharge port 112 and pass through the large-pore filter 23 and the small-pore filter. Filter 22 to flow into the container 211 .

Step S18: Let the discharge valve 12 of the frying unit 1 close the discharge port 112, and then let the motor body 32 of the motor unit 3 exert force on the conduit 31 to drive the edible food located in the container 211. The oil flows back into the frying tank 111 through the conduit 31 .

Step S19: Let the top cover 41 of the sterilization unit 4 cover the frying tank 111, and then make the ultraviolet lamp 42 face the frying tank 111 and irradiate the frying tank 111 with ultraviolet light to prevent the backflow into the frying tank. The edible oil in tank 111 is sterilized. At this point, after the edible oil in the frying tank 111 has been completely filtered, it is continuously sterilized to extend the service life of the edible oil.

After actual testing by the applicant, the frying operation lasts for one operation time every day, and the operation time is actually between 4 and 6 hours. After the frying operation is stopped, the edible oil is first filtered by the oil filter unit 2 and the motor unit 3, and then the edible oil is sterilized by the sterilization unit 4 until the frying operation is resumed the next day. By filtering and sterilizing the edible oil until the fourth day, the total polar compound content of the edible oil is only 18%, which is lower than the legal requirement of our country (25%).

Therefore, this new oil filtration and sterilization system can produce the following effects:

(1) Filter the edible oil through the oil filter unit 2, and use physical filtration methods throughout the process to ensure that the filtered edible oil has no concerns about chemical residues, allowing consumers to eat healthily.

(2) Filter the edible oil through the oil filter unit 2, and sterilize the edible oil flowing back into the frying tank 111 through the sterilization unit 4, extending the service life of the edible oil and reducing the cost of the operator .

(3) Filter the edible oil through the oil filter unit 2, and sterilize the edible oil flowing back into the frying tank 111 through the sterilization unit 4, thereby reducing oil smoke generated during frying operations and improving the working environment.

(4) Filter the edible oil through the oil filter unit 2, and drive the edible oil in the container 211 through the motor body 32 to flow back into the frying tank 111 through the conduit 31, flushing the oil in the frying tank 111. The fried powder chips remaining in the tank 111 reduce the difficulty of cleaning the frying tank 111, which can significantly reduce the cleaning time and improve operating efficiency.

To sum up, this new oil filtering and sterilizing system can achieve the purpose of this new type of oil filtering and sterilizing system through the above-mentioned components to produce multiple effects.
