Description

Technical Field

[0001] This utility model relates to the field of edible oil processing technology, and in particular to an edible oil processing and extraction device. Background Technology

[0002] Edible oil, also known as cooking oil, refers to animal or vegetable fats used in food preparation. It is liquid at room temperature. Due to differences in raw material sources, processing techniques, and quality, most common edible oils are vegetable oils, including corn oil, rapeseed oil, peanut oil, hemp seed oil, corn oil, olive oil, camellia oil, palm oil, rapeseed oil, sunflower seed oil, soybean oil, sesame oil, flaxseed oil, grapeseed oil, walnut oil, peony seed oil, and so on.

[0003] Pressing is a traditional method for processing and extracting edible oil. The specific process involves first squeezing the oil out of the oilseeds using mechanical pressure, and then filtering out solid impurities such as plant fibers and cake fragments from the squeezed crude oil to obtain relatively pure edible oil.

[0004] In existing technologies, single-layer filter screens are often used to filter solid impurities in crude edible oil. This causes solid impurities to easily adhere to the filter screen and quickly clog it. After clogging, the filter screen needs to be cleaned, which usually requires pausing the filtration process and seriously affects the filtration efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an edible oil processing and extraction device, which, by setting up a multi-stage filtration device, enables different filter screens to filter solid impurities of different particle sizes in stages, thereby reducing the probability of filter screen clogging, extending the single filtration time, effectively reducing the frequency of filter screen cleaning, and improving filtration efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An edible oil processing and extraction device includes a housing, a top cover at the top of the housing, a feed inlet on the top cover, a filter assembly slidably disposed within the housing, a vacuum pump disposed on the side wall of the housing, and a discharge outlet at the bottom of the housing. The filter assembly includes a filter cylinder slidably disposed within the housing with openings at both the top and bottom, multiple filter screens distributed vertically within the filter cylinder and detachably connected to the filter cylinder, and a limiting assembly that limits each filter screen to the filter cylinder. Among the multiple filter screens, the mesh size gradually decreases from top to bottom.

[0008] Preferably, the outer wall of the filter cartridge is provided with a slider, and the inner wall of the housing is provided with a vertical groove that slides with the slider; the top of the vertical groove passes through the side wall of the housing and communicates with the outside.

[0009] Preferably, the limiting component includes a sealing ring disposed at the edge of each of the filter screens.

[0010] Preferably, the limiting component further includes a limiting block disposed at the bottom end of each of the filter screens, and a limiting groove disposed on the side wall of the filter cylinder and slidingly engaged with the limiting block.

[0011] Preferably, the limiting block is cylindrical.

[0012] Preferably, the top wall of the filter cartridge and the bottom wall of the top cover are in contact with each other.

[0013] Preferably, each filter screen has a pull rod at the top.

[0014] Preferably, the inner wall of the box is provided with a non-stick coating.

[0015] Preferably, the bottom wall of the box is inclined downward along the direction of the discharge port.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By allowing the filter cartridge to slide inside the housing and by providing a top cover at the top of the housing, the filter cartridge and its internal components can be easily disassembled and installed.

[0018] By defining the filter components, including a filter cylinder that is slidably installed inside the chamber with openings at both the top and bottom, and multiple filter screens distributed vertically inside the filter cylinder, multiple layers of filter screens can be formed inside the chamber, thus forming a multi-stage filtration device. Combined with the vacuum pump's vacuuming action, it is possible to filter solid impurities of different particle sizes in stages, thereby reducing the probability of filter screen clogging, extending the single filtration time, effectively reducing the frequency of filter screen cleaning, and improving filtration efficiency.

[0019] By making the connection between the filter cartridge and the filter screen detachable, the filter screen can be easily removed from the filter cartridge when it becomes clogged or needs cleaning or maintenance.

[0020] By setting a limiting component that limits multiple filter screens to the filter cartridge, it is possible to ensure that the filter screens are firmly fixed inside the filter cartridge, thereby improving filtration stability. Attached Figure Description

[0025] Example 1

[0026] In existing technologies, single-layer filter screens are often used to filter solid impurities in crude edible oil. This causes solid impurities to easily adhere to the filter screen and quickly clog it. After clogging, the filter screen needs to be cleaned, which usually requires pausing the filtration process and seriously affects the filtration efficiency.

[0027] Based on this, the present invention provides an edible oil processing and extraction device, such as... Figure 1-2 As shown, the system includes a housing 1, a top cover 2 at the top of the housing 1 (the top cover 2 and the housing 1 can be threaded together), a feed inlet 3 on the top cover 2, a filter assembly slidably disposed within the housing 1, a vacuum pump 4 disposed on the side wall of the housing 1 (this is prior art, designed to extract air from the housing 1 to provide a vacuum environment for the housing 1, thereby improving filtration efficiency), and a discharge port 5 at the bottom of the housing 1 (a piston is disposed within the discharge port 5, not shown in the figure); Figure 1-2 As shown, the filter assembly includes a filter cylinder 6 that is slidably disposed inside the housing 1 and has an open top and bottom, a plurality of filter screens 7 that are distributed vertically inside the filter cylinder 6 and detachably connected to the filter cylinder 6, and a limiting component that limits the filter screens 7 to the filter cylinder 6 one by one; among the plurality of filter screens 7, the mesh size gradually decreases from top to bottom.

[0028] Furthermore, such as Figure 1-2 As shown, the outer wall of the filter cartridge 6 is provided with a slider 8, and the inner wall of the housing 1 is provided with a vertical sliding groove 9 that slides with the slider 8. The top end of the vertical sliding groove 9 penetrates the side wall of the housing 1 and communicates with the outside. By providing the vertical sliding groove 9, the bottom end of the filter cartridge 6 can be limited to the housing 1, that is, the bottom end of the filter cartridge 6 can be supported. Further, as... Figure 1-3As shown, the limiting component includes a sealing ring 10 disposed on the edge of each filter screen 7. After the sealing ring 10 is disposed, the filter screen 7 with the sealing ring 10 and the filter cylinder 6 are interference-fitted, which can initially limit the filter screen 7 to the filter cylinder 6. However, because the bottom of the filter screen 7 lacks certain support, under the gravity of the cooking oil, the filter screen 7 may slide down, thus causing the sealing ring 10 to fail to limit the filter screen. Based on this, further, as... Figure 1-3 As shown, the limiting assembly also includes a limiting block 11 disposed at the bottom end of each of the filter screens 7, and a limiting groove 12 disposed on the side wall of the filter cylinder 6 and slidingly engaged with the limiting block 11, wherein there is almost no gap between the limiting block 11 and the limiting groove 12, therefore Figure 1 The limiting groove 12 is not shown in the drawing. Figure 3 The drawing of the limiting groove 12 only shows the positional relationship between the limiting block 11 and the limiting groove 12.

[0029] Working principle: Place the top cover 2 on the chamber 1, then turn on the vacuum pump 4 and add crude edible oil through the feed inlet 3. Under the action of the vacuum pump 4, a negative pressure is formed inside the chamber 1, allowing the crude oil to quickly pass through all the filter screens 7. Solid impurities such as plant fibers and cake fragments in the crude oil are retained by the matching filter screens 7. If you need to remove the filtered edible oil, simply open the piston to remove it. After filtration is complete, open the top cover 2 and drag the filter cylinder 6 upwards, allowing the slider to slide upwards in the vertical groove. After it has completely slid out, pull out the top filter screen 7. Then slide the limiting block 11 below the filter screen 7 outwards until the next filter screen 7 can be pulled out upwards. Then, remove the lower filter screens 7 one by one in the same way.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1-2 As shown, the limiting block 11 is cylindrical, which reduces the residue of cooking oil at the top of the limiting block 11. Furthermore, as... Figure 1 As shown, the top wall of the filter cylinder 6 and the bottom wall of the top cover 2 are in contact with each other. The top cover 2 helps to limit the top of the filter cylinder 6. Through the combined action of the vertical sliding groove 9 and the top cover 2, the entire filter cylinder 6 is contained within the housing 1. Furthermore, as... Figure 1 As shown, each filter screen 7 is equipped with a pull rod 13 at its top. After the filter cylinder 6 is removed from the housing 1, the filter screen 7 can be easily removed one by one from the filter cylinder 6 by pulling the pull rod 13, improving the ease of removal. Furthermore, the inner wall of the housing 1 is provided with a non-stick coating (existing technology, not shown in the figure) to reduce cooking oil residue on the inner wall of the housing 1. Further, as... Figure 1As shown, the bottom wall of the box 1 is inclined downward along the direction of the discharge port 5 to further reduce the residue of edible oil inside the box 1.
