Description

Technical Field

[0001] This utility model relates to the field of fried food technology, and in particular to a filtration device for processing fried food. Background Technology

[0002] Deep-frying is a cooking method. When fried until burnt, polycyclic aromatic hydrocarbons are produced. [1] Whether it is fried dough twists, spring rolls, or meatballs during festivals, or fried dough sticks, fried cakes, or fried dough fritters eaten for breakfast every day, or fried fries, fried bread, fried chicken wings, and fried potato chips and fried biscuits in Western fast food that children like to eat, they are all deep-fried foods.

[0003] When frying food, a large amount of food residue is easily left in the cooking oil, affecting the oil quality. Therefore, a convenient frying filter is needed. Traditional frying filters require pouring out the oil when filtering cooking oil, which is time-consuming and laborious. Moreover, after the filter screen removes the residue, it is inconvenient to clean the residue or the filter screen, making it inconvenient to use. Utility Model Content

[0004] The technical problem this invention aims to solve is to address the aforementioned technical deficiencies by providing a filtering device for processing fried foods. This structure can collect and clean food residue inside the fryer, facilitating the cleaning and recycling of the filter screen, and making edible oil filtration more convenient.

[0005] The technical solution adopted by this utility model is as follows: a filtering device for processing fried food is provided, including an hourglass-shaped frying shell; an oil outlet pipe is connected to the lower end of the frying shell; a knife gate valve is provided on the outside of the oil outlet pipe; a filter screen is provided at the lower end of the oil outlet pipe; a support is provided on the outside of the frying shell; a drive motor is installed on the support; a piston is provided in the middle of the frying shell and slides and seals with the oil outlet pipe; a threaded pipe is fixedly connected to the upper end of the piston; a threaded rod is threadedly connected to the upper end of the threaded pipe; the upper end of the threaded rod penetrates the support and is fixedly connected to the output end of the drive motor, and the threaded rod is rotatably connected to the support; a telescopic rod is provided between the support and the piston.

[0006] To further optimize this technical solution, a toothed ring is rotatably connected to the outer side of the upper end of the frying shell of a filtration device for processing fried food; a scraper is slidably attached to the inner side wall of the frying shell; the upper end of the scraper is fixedly connected to the toothed ring; and the toothed ring is connected to the drive motor via a transmission device.

[0008] To further optimize this technical solution, a filter pipe is threadedly connected to the lower end of the oil outlet pipe of a filtration device for processing fried food; the filter screen is fixedly connected to the lower end of the filter pipe.

[0009] To further optimize this technical solution, the inner side of the filter tube of a filtration device for processing fried food is flush with the inner side of the oil outlet pipe.

[0010] To further optimize this technical solution, a frying mesh is provided inside the frying shell of a filtration device for processing fried food; the frying mesh is connected to a bracket by bolts.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4 As shown, a filtering device for processing fried food includes an hourglass-shaped frying shell 1; an oil outlet pipe 2 is connected to the lower end of the frying shell 1; a gate valve 3 is installed on the outside of the oil outlet pipe 2; a filter screen 4 is installed at the lower end of the oil outlet pipe 2; a support 5 is installed on the outside of the frying shell 1; a drive motor 6 is installed on the support 5; a piston 7 is installed in the middle of the frying shell 1 and slides and seals with the oil outlet pipe 2; a threaded pipe 8 is fixedly connected to the upper end of the piston 7; a threaded rod 9 is threadedly connected to the upper end of the threaded pipe 8; the upper end of the threaded rod 9 penetrates the support 5 and is fixedly connected to the output end of the drive motor 6, and the threaded rod 9 is rotatably connected to the support 5; a telescopic rod 10 is provided between the support 5 and the piston 7; a toothed ring 11 is rotatably connected to the outer side of the upper end of the frying shell 1; a scraper 12 is slidably attached to the inner wall of the frying shell 1. The upper end of the scraper 12 is fixedly connected to the toothed ring 11; the toothed ring 11 is connected to the drive motor 6 via a transmission device; the transmission device includes a transmission shaft 13 rotatably mounted on the bracket 5; the lower end of the transmission shaft 13 is fixedly connected to a drive gear 14 that meshes with the toothed ring 11; transmission wheels 15 are fixedly connected to the upper end of the transmission shaft 13 and the outer side of the threaded rod 9; the two transmission wheels 15 are connected via a transmission belt 16; the lower end of the oil outlet pipe 2 is threadedly connected to a filter pipe 17; the filter screen 4 is fixedly connected to the lower end of the filter pipe 17; the inner side of the filter pipe 17 is flush with the inner side of the oil outlet pipe 2; a frying net 18 is provided inside the frying shell 1; the frying net 18 is connected to the bracket 5 via bolts 19; a heating wire 20 is provided inside the frying shell 1; an oil receiving tank 21 is provided at the lower end of the filter pipe 17.

[0024] In use, the oil in the frying shell 1 is heated by the heating wire 20, and then the food to be fried is placed in the frying net 18. The frying net 18 filters out most of the food residue, and a small portion of the food residue falls into the frying shell 1. According to the hourglass shape of the frying shell 1, the food residue settles at the oil outlet pipe 2, which makes it easy to filter the food residue, easy to collect the residue, and convenient for food frying processing.

[0025] Over time, excessive food residue accumulates at the oil outlet pipe 2. At this point, the drive motor 6 is activated, causing the threaded rod 9 to rotate. Based on the sliding limit of the piston 7 by the telescopic rod 10, as the threaded rod 9 rotates, the threaded pipe 8, threaded to the threaded rod 9, drives the piston 7 downwards. Before the piston 7 reaches the oil outlet pipe 2, the gate valve 3 is opened, allowing the piston 7 to move downwards into the oil outlet pipe 2, squeezing the oil and residue within. The oil containing a large amount of residue in the oil outlet pipe 2 falls into the oil receiving tank 21. As the piston 7 moves downwards, it contacts the residue, filtering the remaining oil through the filter screen 4 before it flows into the oil receiving tank 21. Then, the filter pipe 17 is rotated, and the filter screen 4 on the filter pipe 17 is cleaned. This facilitates oil filtration and also makes it easy to clean the filter screen 4 for reuse.

[0026] When the drive motor 6 rotates, it also drives the transmission wheel 15 and the transmission belt 16 to rotate, which in turn drives the transmission shaft 13 to rotate. The transmission shaft 13 drives the drive gear 14 to rotate, and the drive gear 14 drives the gear ring 11 that meshes with it to rotate. When the gear ring 11 rotates, it drives the scraper 12 to rotate. When the scraper 12 rotates, it scrapes the residue adhering to the inner wall of the frying shell 1. The scraped food residue is loosened and eventually falls into the oil outlet pipe 2, which makes it easier to clean the residue on the inner wall of the frying shell 1, making it easier to fry food more hygienic. It also makes it easier to clean the residue on the inner wall of the frying shell 1 while the piston 7 moves downward, making it easier to filter the cooking oil. When the piston 7 moves into the oil outlet pipe 2, the scraper 12 can rotate once to clean.

[0027] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
