Technical Field

[0001] The utility model relates to the technical field of oil pressing and filtering, in particular to an oil pressing and filtering device. Background Art

[0002] Edible oil is indispensable in food cooking. Currently, most edible oils used in food production are vegetable oils, which are obtained by processing the raw materials through several oil-making processes. Oil pressing is one of the above processes and plays an important role.

[0003] After the oil is pressed, it will contain impurities from the raw materials. Therefore, the product must be filtered to remove the impurities. Generally, simple filters are used for filtration, which is inefficient and has poor filtering effects. Moreover, the filter is prone to clogging after a period of use, making it difficult to clean and reducing the filtering efficiency. Utility Model Content

The base is fixed at the four corners of the bottom of the filter box, the bottom motor is installed at the center, and a through hole is also opened on the inner bottom surface. A valve is installed in the through hole. When the valve is opened, the filtered oil leaks out from the through hole. An addition frame is installed on the top of the filter box to facilitate the addition of the oil to be filtered. There are two inlets in the addition frame. The lower part of the inlet corresponds to the primary filter part arranged inside the filter box. After the raw oil enters, it first passes through the primary filter. The filter section performs preliminary filtration, a window is provided on the front side of the filter box and is closed by a removable plug, a filter plate cleaning structure is provided at the first-level filter section, through which the surface of the first-level filter section is cleaned after a period of use to reduce the risk of clogging to ensure normal filtration efficiency and effect, a collecting channel is provided below the middle of the filter box below the first-level filter section, the oil after the first-level filtration is collected here and flows downward through the collecting channel, a rotating shaft is rotatably installed on the bottom surface of the filter box, a re-filter frame is fixed on the upper end of the rotating shaft, a side wall filter hole is provided on the side wall of the re-filter frame, the rotating shaft is driven by the bottom motor, the oil after the first-level filtration enters the re-filter frame for re-filtration, and the filtration effect is improved under the action of the high-speed rotation of the rotating shaft driven by the bottom motor.

[0005] As an optimal technical solution of the present invention, the first-level filter part includes an inclined filter plate, an end chip trough, filter holes and a filter plate cleaning structure. Two inclined filter plates are fixed in the filter box. The two inclined filter plates are symmetrical on the left and right, and the lowest ends are connected to a plate body, so that a V-shaped state is formed between the two inclined filter plates and the middle connecting plate body. An end chip trough is fixed to the outside of the highest end, and a number of filter holes are distributed on the inclined filter plate. A filter plate cleaning structure is provided on the inclined filter plate in the filter box. The front end of the end chip trough is connected to the window. The filter plate cleaning structure can push the residue on the inclined filter plate upward to the highest point of the inclined filter plate. At this time, impurities can fall into the end chip trough, and the detachable seal can be opened later to remove the impurities using external tools.

[0006] As an optimal technical solution of the present invention, the filter plate cleaning structure includes a scraper, a rear protrusion, a rear side wall groove, a screw and a built-in motor. Two rear side wall grooves are opened on the rear side wall of the filter box. The rear side wall grooves are arranged parallel to the inclined filter plate. The lower surface of the scraper contacts the inclined filter plate, and the scraper is vertical to the inclined filter plate as a whole. The rear end is integrally formed with a rear protrusion, which is placed in the rear side wall groove and installed in conjunction with the screw rotatably installed in the rear side wall groove. There is a built-in motor in the rear side wall of the filter box, which is used by an external power supply to drive the screw. When the screw rotates, the scraper moves along the rear side wall groove, and the surface of the inclined filter plate is scraped and cleaned during the movement.

[0007] As a preferred technical solution of the present invention, the scraper is made of stainless steel, and the inner side of the upper end of the scraper has a chamfered portion, so that the scrapers on both sides are fitted together through the chamfered portion.

[0008] As a preferred technical solution of the present invention, a protective ring is fixed to the inner bottom surface of the filter box.

[0009] The beneficial effects of the utility model are as follows: the oil to be filtered is filtered for the second time through the primary filter part, the rotating shaft, the secondary filter frame and the side wall filter holes, and the filtering efficiency can be improved under the setting of the bottom motor and the rotating shaft. In order to avoid the filtering efficiency from decreasing due to impurities remaining on the inclined filter plate after a period of use, the inclined filter plate is cleaned in time by the set filter plate cleaning structure to ensure good filtering efficiency.
