Description

Technical Field

[0001] This utility model relates to the field of fried food technology, specifically to a slag removal structure for a fryer. Background Technology

[0002] In the process of industrialized food production, fryers have become core equipment in production lines for fried foods such as French fries, fried chicken, and pastries due to their efficient and stable processing performance. However, fryers inevitably produce oil residue during operation. In existing technologies, a chain drives scraper bars to remove the oil residue from the oil tank through a filter screen and out of the fryer. Coarse residue is carried away by the scraper bars from the discharge end of the fryer. However, the filter screen has low filtration precision, and some coarse residue will also pass through the filter screen and enter the oil residue sedimentation tank, resulting in accumulation. Currently, the solutions in China are generally to increase the filtration precision of the filter screen or use a spiral slag discharge structure. Although increasing the filtration precision of the filter screen can increase the amount of coarse residue discharged, the accumulation of material in the oil residue sedimentation tank still exists, only delaying the time when the accumulation problem occurs. Moreover, the increased filtration precision will slow down the filtration speed of edible oil, affecting the speed of edible oil circulation. The spiral slag discharge structure requires a prime mover, and the motor must be located outside the oil tank. Therefore, a sealing problem will arise between the oil tank and the motor. Long-term high-temperature operation may cause the seal to age and fail, requiring regular maintenance and inspection, and also increasing the difficulty of cleaning. Utility Model Content

[0023] See Figures 1-4A slag removal structure for a deep fryer includes a housing 1, a filter plate 2, a scraper assembly 3, and a sedimentation tank 5. The filter plate 2 is inclinedly disposed on one side inside the oil tank, and an inclined guide plate 4 is provided below the filter plate 2. The sedimentation tank 5 is located at the lower end of the guide plate 4. The scraper assembly 3 is disposed inside the housing 1 and can move along the bottom surface of the housing 1 and the upper surface of the filter plate 2. One end of the sedimentation tank 5 is provided with a filter pipe 7, and the other end of the sedimentation tank 5 is provided with an oil spray pipe 6. The oil spray pipe 6 sprays oil to make the oil residue flow to the filter pipe 7. Here, the lower end of the filter plate 2 is the oil sludge feed end, and the upper end is the oil sludge discharge end. The sedimentation tank 5 is located below the feed end of the filter plate 2. The oil sludge is at the bottom of the box 1. The scraper assembly 3 pushes the oil sludge into the feed end and moves it towards the discharge end. Smaller fine sludge and residual oil on the oil sludge will fall onto the guide plate 4 or sedimentation tank 5 during the movement. Due to the inclined setting of the guide plate 4, the oil sludge on the guide plate 4 will eventually be concentrated in the sedimentation tank 5. The oil sludge that does not fall off will be pushed to the discharge end by the scraper assembly 3 for collection. The oil spraying pipe 6 is connected to the circulation pipe. The spraying direction of the oil spraying pipe 6 is towards the filter pipe 7. While the circulation pipe circulates the filtered oil, the oil spraying pipe 6 sprays oil into the sedimentation tank 5, so that the oil sludge 9 deposited in the sedimentation tank 5 can flow or float. The oil sludge 9 will eventually flow into the filter pipe 7 along with the oil, thereby preventing the accumulation at the bottom of the sedimentation tank 5. The oil flowing into the filter pipe 7 will eventually enter the circulation pipe after filtration.

[0024] To facilitate the cleaning of the sedimentation tank 5 and the filter plate 2, specifically, mounting grooves are provided on both sides of the housing 1, and the filter plate 2 can slide along the mounting grooves and be installed inside the housing 1. Here, by sliding the filter plate 2 inside the housing 1, when it is necessary to clean the filter plate 2 or the sedimentation tank 5, the filter plate 2 can be removed from the oil tank, and the filter plate 2 and the sedimentation tank 5 can be cleaned separately.

[0025] More specifically, the filter plate 2 is provided with at least one handle 21 at the end away from the bottom of the housing 1. Here, there are two handles 21 symmetrically arranged at the feeding end of the filter plate 2. The handles 21 are ring-shaped, and after the oil cools down, the filter plate 2 can be pulled out directly and conveniently by hand. In addition, when there is a situation that requires handling in a high-temperature environment, a tool similar to a hook can be used to remove the filter plate 2 in a high-temperature state.

[0026] More specifically, the housing 1 is equipped with an oil sludge collection box 8, which is located on one side of the top of the filter plate 2. The top of the filter plate 2 partially covers the opening of the oil sludge collection box 8. Here, the oil sludge collection box 8 is positioned below the discharge end of the filter plate 2. When the scraping assembly reaches the end of the filter plate 2, the discharge end of the filter plate 2 covers the opening of the oil sludge collection box 8, allowing all the oil sludge 9 to fall into the oil sludge collection box 8.

[0027] More specifically, the bottom of the oil residue collection box 8 is inclined towards the middle. Here, there is also a small cart (not shown in the figure) at the bottom of the oil residue collection box 8. The design of the bottom of the oil residue collection box 8 being inclined towards the middle can ensure that the oil residue 9 falls into the small cart, which is convenient for cleaning the oil residue 9 later.

[0028] More specifically, the filter plate 2 includes a mounting frame 22 and a filter screen. The filter screen is installed inside the mounting frame 22 and is composed of several triangular prisms 23. These triangular prisms 23 are placed upside down and parallel to each other, with their bottom surfaces forming the upper surface of the filter plate 2. A gap is left between two adjacent triangular prisms 23. Here, the cross-section of the triangular prism 23 is an isosceles triangle, with the face of the other unequal side forming the base. The gap between the triangular prisms 23 is to allow the oil on the oil sludge 9 to flow into the sedimentation tank 5 through the gaps when cleaning the oil sludge 9. The upside-down filter screen can prevent the oil sludge 9 from getting stuck in the gaps and becoming difficult to clean after long-term solidification. The size of the gap between adjacent triangular prisms 23 is between 0.4 and 1 mm. If the gap is too large, too much oil sludge 9 will fall into the sedimentation tank 5, while if the gap is too small, the oil filtration will be slowed down, thus bringing the oil and oil sludge 9 to the feeding end together.

[0029] More specifically, the scraper assembly 3 includes a drive wheel, a driven wheel, a chain connecting the drive wheel and the driven wheel, and scrapers mounted on the chain. Here, several scrapers are evenly spaced on the chain. The scrapers first scrape oil residue 9 from the bottom of the oil tank, then turn at the feed end of the filter plate 2, making the scraper's movement on the filter plate 2 parallel to the upper surface of the filter plate 2. This continues until the scraper reaches the discharge end of the filter plate 2, after which it turns again until it returns to its initial position, and the above process is repeated.

[0030] More specifically, the guide plate 4 is a Teflon plate. Here, in order to prevent the oil residue 9 that falls from the filter plate 2 onto the guide plate 4 from sticking to the guide plate 4, the guide plate 4 is made of a non-stick Teflon material, which makes it easier to clean in subsequent cleaning.

[0031] More specifically, the end of the fuel injection pipe 6 is inclined. Here, the fuel injection pipe 6 is inclined upward to prevent the oil sludge 9 in the sedimentation tank 5 from accumulating too much and becoming unable to flow. The upward inclination of the fuel injection pipe 6 allows the oil sludge 9 accumulated at the top to flow, thereby enabling the oil sludge 9 deposited in the center to flow and be carried away by the filter pipe 7. The angle between the fuel injection pipe 6 and the bottom of the sedimentation tank 5 is within the range of ±0~5 degrees. An angle that is too high or too low will affect the cleaning of the oil sludge 9 in the sedimentation tank 5 by the fuel injection pipe 6.

[0032] The specific slag removal process of this utility model is as follows: After the food is fried, the oil residue is deposited at the bottom of the oil tank. The scraper assembly 3 moves the oil residue 9 deposited at the bottom of the oil tank towards the position of the filter plate 2. When the scraper assembly 3 and the filter plate 2 work relative to each other, the oil brought by the scraper assembly 3 and the oil residue 9 itself will flow into the sedimentation tank 5 through the gap of the filter plate 2. The coarse residue is continued to be sent to the discharge end by the scraper assembly 3 until it falls into the oil residue collection box 8. The fine residue that falls through the gap of the filter plate 2 will slide into the sedimentation tank 5 due to the action of the guide plate 4. The oil spraying pipe 6 continuously sprays oil in the sedimentation tank 5 to make the fine residue flow in the sedimentation tank 5 and prevent the fine residue in the sedimentation tank 5 from accumulating until the fine residue flows into the filter pipe 7.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
