Description

Technical Field

[0001] This invention relates to the field of oil pressing equipment technology, specifically to a home oil press based on low-temperature cold pressing technology. Background Technology

[0002] With the increasing popularity of healthy eating concepts, households are placing higher demands on the safety, nutritional value, and flavor purity of cooking oils. Low-temperature cold pressing technology, with its unique advantages, has become the preferred method for oilseed processing. Low-temperature cold pressing is typically carried out in an environment below 60℃, eliminating the need for high-temperature refining and chemical solvents. This maximizes the preservation of unsaturated fatty acids, vitamins, phytosterols, and other natural active nutrients in the oilseeds, avoiding nutrient loss and the formation of harmful substances caused by high-temperature processing. The resulting oil is clear in color, pure in flavor, and free of chemical residues, meeting the modern family's pursuit of natural and healthy foods. It is particularly suitable for processing oilseeds rich in high-quality nutrients, such as peanuts, camellia seeds, walnuts, and flax seeds, satisfying consumers' demand for high-quality homemade cooking oil.

[0003] While current low-temperature cold-pressing home oil presses on the market have initially achieved cold-pressing functionality, they still have many shortcomings in actual use, making it difficult to fully meet the convenience and practicality needs of home users. Most of these machines adopt a single-station design, requiring separate operations for feeding, pressing, and slag removal, resulting in a disjointed workflow, low oil pressing efficiency, and a large size that cannot meet the needs of home processing. At the same time, oil residue tends to clump and adhere to the inner wall of the pressing chamber, making it difficult for existing slag removal structures to clean thoroughly and reducing the oil yield of subsequent pressing.

Detailed Implementation

[0023] The embodiments of the present invention will be described below with reference to relevant examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0024] like Figures 1 to 9As shown, this invention provides a home oil press based on low-temperature cold pressing technology, including a pressing barrel 1 and a lifting pressure component 2 disposed within the pressing barrel 1. The lifting pressure component 2 includes a pressing electric cylinder 21 disposed at the top of the pressing barrel 1 and a lifting plate 22 disposed within the pressing barrel 1 and connected to the pressing electric cylinder 21. A rotating base 3 is disposed at the bottom of the pressing barrel 1, and a rotating platform 31 rotatably connected to the pressing barrel 1 is disposed on the rotating base 3. A first motor 32, which is drively connected to the rotating base 3, is disposed on the outer wall of the bottom of the pressing barrel 1. Four mounting slots 33 are provided through the rotating platform 31 in a rotationally symmetrical manner. An oil pressing cone 4 is disposed within each mounting slot 33. A flipping component 47 is disposed within each mounting slot 33 of the oil pressing cone 4. An equally spaced mounting cavity 41 is disposed inside the side wall of the oil pressing cone 4. A push plate 43 is slidably connected to the top of the 41. A water bladder 42 is provided between the push plate 43 and the bottom of the mounting cavity 41. Oil outlet holes 40 are evenly distributed through the inner wall of the oil pressing cone 4 between the push plates 43. The flipping component 47 is installed on the middle of the outer side of the oil pressing cone 4 with a mounting ring plate 471. A circulating cooling component 49 is connected to the lower surface of the mounting ring plate 471. The circulating cooling component 49 is connected to the water bladder 42. The lower surface of the lifting plate 22 is provided with a feeding component 5, a pressing component 6, and a slag cleaning component 7 arranged in a ring and corresponding to the position of the oil pressing cone 4. The pressing component 6 includes a pressure cone 61 connected to the lower surface of the lifting plate 22 and a circulating cooling machine 62 provided on the upper surface of the lifting plate 22. A cavity is provided inside the pressure cone 61. The circulating cooling machine 62 is provided with a circulation pipe 63 connected to the cavity.

[0025] This invention achieves continuous automated operation of feeding, pressing, cleaning, and slag removal, significantly improving the efficiency of home oil pressing. The rotating base 3 has four rotationally symmetrically distributed mounting slots 33 on its rotating table 31. Each mounting slot 33 is equipped with an oil pressing cone 4, corresponding to the feeding station, pressing station, cleaning station, and slag removal station. The lower surface of the lifting plate 22 is equipped with a feeding component 5, a pressing component 6, and a slag removal component 7. When the rotating base 3 drives the rotating table 31 to rotate through the first motor 32, the four oil pressing cones 4 synchronously switch between the four stations. The lifting plate 22 descends to allow each component to synchronously operate on the corresponding oil pressing cone 4, eliminating the need for step-by-step operation and solving the problem of discontinuous process in traditional equipment.

[0026] In terms of slag removal, the various components work together to thoroughly clean the oil residue, preventing a decrease in oil yield. When the oil pressing cone 4 reaches the cleaning station, the delivery pump 495 of the circulating cooling component 49 fills the water bladder 42 with liquid. The water bladder 42 expands and pushes up the push plate 43, causing the push plate 43 to protrude from the inner wall of the oil pressing cone 4, breaking up the attached oil residue clumps. After the water bladder 42 is depressurized and reset, the third motor 71 of the slag removal component 7 drives the conical cleaning brush 72 to rotate, performing a deep cleaning of the inner wall of the oil pressing cone 4. When it reaches the slag discharge station, the second motor 473 of the tilting component 47 drives the rotating shaft 472, causing the mounting ring plate 471 and the oil pressing cone 4 to tilt. At the same time, the lifting plate 22 presses down the pressing column 48 to discharge the residual oil residue inside and at the bottom of the oil pressing cone 4.

[0027] The refrigeration device 492 of the circulating refrigeration component 49 cools the liquid in the water tank 491 through the refrigeration rod 493 and sends it to the water bag 42 of the oil pressing cone 4 through the delivery pump 495 to cool the oil pressing cone 4; at the same time, the circulating refrigeration unit 62 of the pressing component 6 delivers a cold source to the liquid chamber of the pressure cone 61 through the circulation pipe 63 to ensure that the low temperature is maintained throughout the pressing process, so as to retain the natural nutrients such as unsaturated fatty acids and vitamins in the oil to the greatest extent and avoid the generation of harmful substances.

[0028] As one of the preferred embodiments of the present invention Figures 1 to 3 As shown, the outer walls of the mounting ring plate 471 are provided with rotating shafts 472 that are rotatably connected to the inner wall of the mounting groove 33. The outer wall of the rotating base 3 is provided with a second motor 473 that is drively connected to the rotating shafts 472. The bottom of the pressing barrel 1 is provided with an oil outlet hopper 11 corresponding to the position of the pressing component 6. The bottom of the pressing barrel 1 is provided with a slag outlet hopper 12 corresponding to the position of the slag cleaning component 7.

[0029] The mounting ring plate 471 is rotatably engaged with the inner wall of the mounting groove 33 via the rotating shafts 472 on both sides. The second motor 473 is connected to the rotating shafts 472 for transmission, forming the overturning drive structure of the oil pressing cone 4. When the oil pressing cone 4 rotates with the rotary table 31 to the slag discharge station, the second motor 473 starts and drives the rotating shafts 472 to rotate, thereby driving the mounting ring plate 471 and the oil pressing cone 4 to overturn. Combined with the downward pressing action of the pressing column 48, the residual oil residue inside is smoothly discharged. The oil outlet hopper 11 at the bottom of the pressing barrel 1 corresponds to the pressing station and is just right to receive the oil seeping out of the oil pressing cone 4 during the operation of the pressing component 6. The slag outlet hopper 12 corresponds to the position of the slag cleaning component 7 and the slag discharge station. It can collect the oil residue cleaned by the slag cleaning component 7 and also receive the residue discharged from the oil pressing cone 4 after overturning, realizing the orderly separation of oil residue and adapting to the needs of continuous automated operation of the equipment.

[0030] As one of the preferred embodiments of the present invention, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, the circulating refrigeration component 49 includes a water tank 491 disposed on the lower surface, a refrigeration device 492 disposed on the outer wall of the water tank 491, a refrigeration rod 493 disposed inside the water tank 491 and connected at one end to the refrigeration device 492, a delivery pump 495 and a liquid extraction pump 496 respectively disposed on both sides of the oil pressing cone 4 and installed on the lower surface of the water tank 491. The lower end of the oil pressing cone 4 is provided with a delivery ring pipe 494, which is connected to a plurality of water bladders 42 inside the oil pressing cone 4. The delivery pump 495 and the liquid extraction pump 496 are respectively connected to the water tank 491 and the delivery ring pipe 494.

[0031] The water tank 491 stores coolant. After the refrigeration device 492 on the outer wall is activated, it rapidly cools the liquid in the water tank 491 via a connected cooling rod 493. The conveying ring pipe 494 at the lower end of the pressing cone 4 acts as a diversion pipe, evenly distributing the coolant to multiple water bladders 42 within the pressing cone 4. The conveying pump 495 and the liquid extraction pump 496 respectively handle the liquid supply and return functions. The conveying pump 495 and the liquid extraction pump 496 are connected to the water tank 491 and the conveying ring pipe 494, allowing the coolant to circulate between the water tank 491, the conveying ring pipe 494, and the water bladders 42, continuously cooling the pressing cone 4 and ensuring a low-temperature environment throughout the pressing process. Simultaneously, when the conveying pump 495 fills the water bladders 42, the expansion of the water bladders 42 can push up the push plate 43 to break up oil residue agglomerates. After the liquid extraction pump 496 extracts the liquid, the water bladders 42 contract and return to their original position, avoiding affecting the subsequent cleaning effect of the slag removal assembly 7.

[0032] As one of the preferred embodiments of the present invention, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the push plate 43 has sliders 341 at both ends, and the inner wall of the mounting cavity 41 has a sliding groove 44 that can slide with the sliders 341. The push plate 43 has guide grooves 342 at both ends, and a guide rod 45 is provided in the guide grooves 342. One end of the guide rod 45 is vertically installed on the bottom inner wall of the mounting cavity 41. A first spring 46 is sleeved on the outside of the guide rod 45. The two ends of the first spring 46 are respectively connected to the push plate 43 and the bottom inner wall of the mounting cavity 41. A retractable pressing column 48 is provided through the center of the bottom of the oil pressing cone 4. A second spring 481 is sleeved on the outside of the pressing column 48. The two ends of the second spring 481 are respectively connected to the top of the pressing column 48 and the bottom of the oil pressing cone 4. A plurality of oil outlet holes 40 are evenly distributed around the pressing column 48 at the bottom of the oil pressing cone 4.

[0033] The sliders 341 at both ends of the push plate 43 are embedded in the grooves 44 on the inner wall of the mounting cavity 41, forming a sliding limit to prevent the push plate 43 from deviating when moving. At the same time, the guide rod 45 at the bottom of the mounting cavity 41 is vertically inserted into the guide groove 342 of the push plate 43, further constraining the movement trajectory of the push plate 43, so that it can only extend and retract smoothly up and down. The first spring 46 outside the guide rod 45 is always in an energy storage state. When the water bladder 42 is depressurized and contracted, the first spring 46 will quickly pull the push plate 43 back to its original position, returning it to a state flush with the inner wall of the oil pressing cone 4, without affecting subsequent pressing or slag removal operations.

[0034] The oil outlet 40, which is set around the pressing column 48 at the bottom of the oil pressing cone 4 and the oil outlet 40 on the inner wall of the oil pressing cone 4, is the main channel for oil discharge during the pressing process. The oil after low-temperature pressing can quickly seep out through the oil outlet 40. The pressing column 48 is equipped with an external second spring 481. With the support of the second spring 481, the top of the pressing column 48 is flush with the bottom of the inner surface of the oil pressing cone 4, which does not affect the pressing. When the residue is discharged, the pressing column 48 is pressed down by the lifting plate 22. The bottom of the pressing column 48 can lift the oil residue remaining at the bottom. With the flipping action of the oil pressing cone 4, the oil residue is discharged, avoiding the oil residue from clogging the oil outlet 40 or adhering to the bottom and affecting the subsequent oil extraction efficiency.

[0035] As one of the preferred embodiments of the present invention, such as Figure 2 and Figure 8 As shown, the feeding assembly 5 includes a feeding pipe 54 vertically penetrating the lifting plate 22 and located above the oil pressing cone 4, a double-cone distribution platform 53 located at the outlet of the feeding pipe 54, a distributor 52 located at the feeding end of the feeding pipe 54, and a telescopic feeding pipe 51 penetrating the top of the pressing barrel 1 and connected to the distributor 52 at its lower end. The middle part of the double-cone distribution platform 53 is connected to the inner wall of the outlet of the feeding pipe 54 through a connecting rod. The upper cone part of the double-cone distribution platform 53 is placed inside the outlet of the feeding pipe 54, and the lower cone part of the double-cone distribution platform 53 is placed outside the outlet of the feeding pipe 54.

[0036] Furthermore, the distributor 52 includes a housing, a distributor disk 521 disposed inside the housing, and a fourth motor disposed on the outer wall of the housing and drivenly connected to the rotating shaft of the distributor disk 521. The distributor disk 521 is provided with a plurality of distributor slots 522 distributed in a rotationally symmetrical manner.

[0037] The telescopic feed pipe 51 of the feeding assembly 5 passes through the top of the pressing barrel 1 and is connected to the distributor 52. It can flexibly extend and retract with the lifting plate 22. The fourth motor of the distributor 52 drives the internal distribution plate 521 to rotate. The distribution groove 522 on the distribution plate 521 will receive the oil in sequence. When it rotates to the corresponding position, the material is discharged into the feed pipe 54. The single feeding amount is controlled by the capacity of the distribution groove 522 to achieve quantitative feeding and avoid too much or too little oil in the oil pressing cone 4, which will affect the pressing effect.

[0038] The design of the double-cone distribution platform 53 ensures more even distribution of the oil, facilitating subsequent pressing. The upper cone of the double-cone distribution platform 53 is located inside the outlet of the feed pipe 54. When the oil falls, it collides with the upper cone and evenly disperses along the cone surface from the gap between the distribution platform and the feed pipe 54. The lower cone of the double-cone distribution platform 53 extends into the pressing cone 4. Because its shape matches the inside of the pressing cone 4 and its size is smaller, it creates a space between the two, allowing the oil to naturally adhere to the inner wall of the pressing cone 4. When the double-cone distribution platform 53 rises with the lifting plate 22 and detaches from the pressing cone 4, a conical groove adapted to the pressure cone 61 is formed inside the oil. This facilitates the smooth entry of the pressure cone 61 and prevents the oil from collapsing when squeezed, ensuring a stable pressing process.

[0039] As one of the preferred embodiments of the present invention, such as Figure 1 and Figure 9 As shown, the pressing assembly 6 includes a pressure cone 61 disposed above the oil pressing cone 4 and connected to the lower surface of the lifting plate 22, and a circulating refrigeration unit 62 disposed on the upper surface of the lifting plate 22. The pressure cone 61 has a liquid chamber inside, and the circulating refrigeration unit 62 is provided with a circulation pipe 63 for communicating with the liquid chamber of the pressure cone 61.

[0040] The pressure cone 61 is fixed to the lower surface of the lifting plate 22, and its position corresponds precisely to the oil pressing cone 4. It can flexibly enter and exit the oil pressing cone 4 as the lifting plate 22 rises and falls. The conical structure of the pressure cone 61 matches the shape of the inner wall of the oil pressing cone 4, and it can form a uniform pressure field when pressed down, so as to fully squeeze the oil in the oil pressing cone 4.

[0041] It should be noted that the circulating chiller 62 is existing technology. Its structure includes a circulating pump and a chiller connected to the circulating pump, primarily responsible for providing a continuous cooling source to the pressure cone 61. The liquid chamber inside the pressure cone 61 is the space for the coolant. The circulating pipe 63 connects the liquid chamber to the circulating chiller 62, forming a complete refrigeration cycle. During operation, the chiller first cools the coolant, and then the circulating pump sends the low-temperature coolant into the liquid chamber of the pressure cone 61 through the circulating pipe 63 to absorb the heat generated during the pressing process. The heated coolant then flows back to the chiller for further cooling, and this cycle repeats continuously.

[0042] As one of the preferred embodiments of the present invention, such as Figure 2 and Figure 7 As shown, the slag cleaning assembly 7 includes a conical cleaning brush 72 disposed above the oil pressing cone 4, a third motor 71 disposed on the upper surface of the lifting plate 22, and a cover plate 73 disposed above the conical cleaning brush 72 and connected to the lower surface of the lifting plate 22. The third motor 71 is connected to the rotating shaft of the conical cleaning brush 72 via a transmission connection.

[0043] The third motor 71 is fixed to the upper surface of the lifting plate 22, and its output shaft is directly driven by the rotation shaft of the conical cleaning brush 72. The cover plate 73 is installed on the lower surface of the lifting plate 22 and covers the conical cleaning brush 72. This not only prevents oil residue from splashing and contaminating the inside of the equipment during cleaning, but also protects the transmission structure of the cleaning brush. The shape of the conical cleaning brush 72 matches the contour of the inner wall of the oil pressing cone 4. When the oil pressing cone 4 rotates to the cleaning position with the rotary table 31, the lifting plate 22 descends, causing the cleaning brush to extend into the cylinder. After the third motor 71 starts, the cleaning brush rotates at high speed. In conjunction with the water bladder 42 lifting the oil residue clumps broken by the push plate 43, it can completely peel off the residual oil residue attached to the cylinder wall. The peeled oil residue falls directly into the corresponding slag hopper 12 at the bottom of the pressing barrel 1, ensuring that there is no residue on the inner wall of the oil pressing cone 4.

[0044] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
