Description

Technical Field

[0001] The utility model relates to the technical field of potato chip frying processing, in particular to a multi-stage filtering self-circulating oil filtering mechanism and a potato chip frying device. Background Art

[0002] Potato chips refer to snacks made from potatoes. The potato chips are made by cutting the potatoes into thin slices, frying or baking them until crispy and then seasoning them. In the potato chip production process, frying is an important work process. In order to avoid the presence of more dirt in the oil after frying and interfere with the subsequent frying work, and to improve the efficiency of the use of edible oil, a special circulating oil filter device is often used.

[0003] According to an oil filter device for potato chip processing equipment disclosed in a patent website (authorization announcement number: CN217773492U), the oil filter device for potato chip processing equipment includes a No. 1 filter mechanism, a centrifugal filter mechanism and a No. 2 filter mechanism. A No. 1 connecting pipe is connected between the No. 1 filter mechanism and the centrifugal filter mechanism, a No. 2 connecting pipe is connected between the centrifugal filter mechanism and the No. 2 filter mechanism, a No. 1 electric pump is fixedly arranged in the middle of the No. 1 connecting pipe, and a No. 2 electric pump is fixedly arranged in the middle of the No. 2 connecting pipe. The edible oil passes through the No. 1 filter mechanism, the centrifugal filter mechanism and the No. 2 filter mechanism in turn through the No. 1 connecting pipe and the No. 2 connecting pipe. The three mechanisms adopt different filtering principles and apply a variety of filtering means to make the edible oil undergo multiple filtrations, which can effectively filter and adsorb food residues, impurities and harmful substances in the edible oil, enhance the filtering effect, and improve the quality of the output edible oil and work efficiency.

[0004] In view of the above description, the applicant believes that the following problems exist: during the use of the above-mentioned prior art, although it can filter the edible oil through multiple filtration processes by setting up three groups of filtering mechanisms, adopting different filtering principles, and applying a variety of filtering methods to improve the quality of the output edible oil, in actual applications, when the device filters the edible oil, since the oil stains in the edible oil will adhere to the filter surface of the No. 1 filter mechanism, the filter surface can only be cleaned by disassembling the filter. However, during the disassembly process, the oil stains on the top are easy to fall into the No. 1 filter mechanism, causing secondary pollution to the edible oil. Moreover, the device can only add the residual oil from the oil inlet pipe to the filtering mechanism, and does not extract the edible oil in the potato chip frying device, so it is difficult to complete the self-circulating oil filtering operation, and there is a problem of poor oil filtering efficiency. Therefore, we urgently need a multi-stage filtration self-circulating oil filtering mechanism and a potato chip frying device to solve the above problems. Utility Model Content

[0029] Furthermore, the filtering and anti-blocking collection mechanism 7 also includes an oil collection component 72, which includes a connecting frame 721, a collection frame 722 is slidably installed inside the connecting frame 721, a mounting rod 723 is fixedly installed inside the collection frame 722, a movable baffle 724 is rotatably installed outside the mounting rod 723, a first connecting frame 725 is provided at one end of the movable baffle 724 near the inner side of the collection frame 722, a second connecting frame 726 is fixedly installed at the top end of the collection frame 722, movable rods 727 are rotatably installed inside the first connecting frame 725 and the second connecting frame 726, and a damping spring 728 is provided outside the movable rod 727 to facilitate the effective collection of the scraped oil, and the movable baffle 724 can be dynamically opened to avoid interference with subsequent filtering work.

[0030] Furthermore, the damping spring 728 is arranged between the two groups of movable rods 727, the collecting frame 722 is in contact with the sewage trough on one side close to the sewage trough, and an installation groove is opened inside the connecting frame 721 at a position corresponding to the collecting frame 722, so that when the scraper 716 is out of contact with the movable baffle 724, the movable baffle 724 can be restored to the closed state with respect to the collecting frame 722.

[0031] Example 2: Please refer to Figure 7-Figure 8 In combination with the first embodiment, it is further obtained that the potato chip frying device includes a potato chip frying area 6 for frying potato chips, a support platform 61 is provided in the potato chip frying area 6, an oil storage frame 62 is fixedly installed on the top of the support platform 61, an electric heating pipe 63 is provided inside the oil storage frame 62, a storage frame 64 is provided in the oil storage frame 62, a hanging ear 65 is fixedly installed on the top of the storage frame 64, a handle 66 is provided on the top of the hanging ear 65, and an oil pump 67 is provided outside the oil storage frame 62 to facilitate the frying of potato chips, and the edible oil in the oil storage frame 62 can be extracted to perform self-circulation.

[0032] Furthermore, the oil storage frame 62 is fixedly installed on the oil outlet end of the third filtering circulation area 5, the oil pump 67 is connected to the first filtering circulation area 3 away from the side of the oil storage frame 62, and the bottom of the hanging ear 65 can contact the top of the oil storage frame 62, so as to facilitate the placement of the object frame 64. After the frying work is completed, the fried potato chips can be unloaded.

[0033] In actual operation, when using the potato chip frying device, edible oil can be added into the oil storage frame 62, and then the electric heating tube 63 is turned on to heat the edible oil, and then the potato chips to be fried are placed into the storage frame 64, and the storage frame 64 can be hung inside the oil storage frame 62 through the hanging ear 65, and then the frying work can be carried out. When the edible oil in the oil storage frame 62 needs to be recycled, a multi-stage filtering self-circulating oil filtering mechanism can be used, and the oil pump 67 can be turned on to extract the edible oil in the oil storage frame 62 and pump it to the first filtering circulation area 3. Inside, the edible oil can be filtered through two groups of filter plates 8. The filtered edible oil is extracted by an electric pump and flows into the second filtering circulation area 4. After the edible oil is centrifugally filtered in the second filtering circulation area 4, it is extracted by an electric pump and enters the third filtering circulation area 5. The edible oil can be filtered under the action of the filter paper 9. When the filter paper 9 needs to be replaced, the inspection window 2 can be opened to replace it. Then, the edible oil that has been filtered at multiple stages will flow back to the oil storage frame 62, ensuring the frying hygiene of potato chips and the efficient use of edible oil. As the first filtering circulation area 3 filters the edible oil multiple times, more impurities and oil stains will adhere to the surface of the filter plate 8. Under the premise of reducing the disassembly work, the driving motor 712 can be turned on to rotate the screw 713. Under the action of the limit rod 714, the movable plate 715 provided can be moved outside the screw 713, so that the oil stains accumulated on the surface of the filter plate 8 can be scraped off under the action of the scraper 716. When the scraper 716 contacts the movable baffle 724, the movable baffle 724 will rotate to push the scraped oil stains into the collection frame 722. For storage, with the reverse rotation of the screw 713, the scraper 716 will return to the initial position, and under the action of the damping spring 728, the set movable rod 727 will rotate. Since the position of the second connecting frame 726 is fixed, the set movable baffle 724 can be restored to the closed state, so as to prevent the oil stains inside the collection frame 722 from interfering with the subsequent filtering work. After the work is completed, the inspection window 2 can be opened, and the collection frame 722 can be pulled to uniformly treat the oil stains collected inside it, and the residual oil residue in the second filtering circulation area 4 can be cleaned.
