Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, specifically a cold pressing device for Sichuan pepper oil. Background Technology

[0002] Sichuan pepper oil is a product made by extracting aroma and flavor compounds from Sichuan peppercorns into an edible vegetable oil. It has a strong numbing sensation, a rich pepper aroma, and a fixed degree of numbing sensation.

[0003] Currently, Sichuan pepper oil extraction mainly includes two methods: hot pressing and cold pressing. Hot pressing refers to pre-treating Sichuan pepper at high temperatures (usually 120-200℃, mainly by roasting) before pressing. After the pepper particles soften and the oil becomes more fluid, they are then pressed using a screw press (or hydraulic press). Its advantages are high oil yield, high raw material utilization, low equipment cost, suitability for large-scale production, and rich flavor that meets the public's demand for strong flavors. However, the problems are the loss of heat-sensitive components, resulting in slightly lower quality; the tendency to produce burnt impurities, requiring deep refining; and poor storage stability, making it prone to oxidation and rancidity.

[0004] Cold pressing is a process that extracts the oil and aroma and flavor substances from Sichuan peppercorns directly through physical pressing (such as a screw cold press) in a low-temperature environment (usually ≤60℃) without high-temperature roasting or only low-temperature drying pretreatment. This process can preserve the original flavor and heat-sensitive nutrients; the product quality is high, there is no risk of scorching, and the storage stability is good.

[0005] In the cold pressing process of Sichuan peppercorns, the peppercorns need to be washed and cleaned before being air-dried and then put into the oil press for oil extraction. If they are not completely dried, the residual water on the surface of the peppercorns will mix directly with the pressed peppercorn oil when they enter the oil press, which can easily breed microorganisms (such as mold and bacteria). This will cause the oil to oxidize and become rancid during storage (producing a rancid taste), greatly shortening the shelf life (the shelf life of oil pressed from undrained materials may be shortened from 10 months to 3-4 months). In addition, the moisture will soften the fiber structure of the green peppercorns, making it easier to produce more fine plant residues (such as peel fragments and fiber strands) during pressing. When these residues mix with water and oil, they will form viscous impurities that are difficult to filter, resulting in cloudy green peppercorn oil and a decline in quality. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a cold pressing device for Sichuan pepper oil. The cold pressing device uses a rotating pressing roller installed in the pressing cylinder to press and transport Sichuan pepper. Combined with the oil receiving trough and slag discharge hopper, a continuous pressing process is realized. At the same time, combined with the air drying mechanism installed in the feeding hopper, the Sichuan pepper entering the pressing cylinder can be easily air dried to avoid water stains remaining on the surface of the Sichuan pepper, which would affect the quality of the pressed oil.

[0007] This utility model is implemented as follows: a cold pressing device for Sichuan pepper oil includes a pressing cylinder, which is kept horizontally by a support. The pressing roller is rotatably installed inside the pressing cylinder to press the peppercorns inside the pressing cylinder to extract oil and convey it to one end; The feed hopper is located above one end of the pressing cylinder and has a drying mechanism inside it; Oil receiving trough plate, arranged at the bottom of the pressing cylinder; The slag discharge hopper is located at the bottom of the press cylinder, away from the feed hopper.

[0008] Preferably, the two ends of the pressing cylinder are mounted on the bracket via connecting discs, and the pressing roller is rotatably disposed inside the pressing cylinder via a rotating connector, with one end extending to the outside of the pressing cylinder and connected to the drive motor via a belt drive mechanism.

[0009] Preferably, the pressing cylinder has a conical structure and oil discharge holes are evenly distributed at the bottom, the feed hopper is connected and disposed above the large end of the pressing cylinder, and the pressing roller has a spiral roller structure.

[0010] Preferably, the air-drying mechanism specifically includes an air inlet pipe disposed on the side end of the feed hopper and connected thereto, and a dispersing component disposed on the inner end of the feed hopper. There are two air inlet pipes in total, which are disposed opposite to each other on both sides of the feed hopper.

[0011] Preferably, the dispersing component includes several dispersing rods disposed on the inner side of the top of the feeding hopper and a feeding baffle disposed below the dispersing rods. The dispersing rods are parallel and disposed at the same height to disperse the peppercorns into the feeding hopper. The feeding baffle is rotatably disposed inside the feeding hopper. The air inlet pipe is disposed on the side wall of the feeding hopper between the dispersing rods and the feeding baffle.

[0012] Preferably, the feed baffle is an arc-shaped plate with a support rod in the middle of the concave surface. The support rod is rotatably mounted on the feed hopper and extends one end to the outside of the feed hopper. A linear drive device and a gear and rack transmission mechanism are provided on the outer end of the feed hopper. The gear of the gear and rack transmission mechanism is sleeved on the outside of the support rod, and its rack meshes with the gear and is driven by the linear drive device.

[0013] Compared with the prior art, the present invention has the following advantages: This cold-pressing device can press and convey Sichuan peppercorns by rotating the pressing rollers set inside the pressing cylinder, so as to press out oil. At the same time, by reasonably setting the shape of the pressing cylinder and the oil receiving trough and slag discharge hopper at the outer end, the oil and residue can be separated and conveyed out, thereby realizing simple filtration of Sichuan peppercorn oil and realizing the continuous oil pressing process of Sichuan peppercorns.

[0014] Meanwhile, by setting up a drying mechanism inside the feeding hopper, residual water stains on the surface of green Sichuan peppercorns can be quickly removed, avoiding oil emulsification, microbial growth, and enzymatic oxidation of fresh numbing components caused by water stains, thus ensuring the clarity of the oil and the purity of its flavor.

[0018] As described in the background section, if the peppercorns are pressed directly with residual water on their outer surface during the cold pressing process, the pressed peppercorn oil will not be able to be stored for a long time and will easily breed microorganisms. In addition, the residue will mix with water and oil during the pressing process, affecting the separation efficiency.

[0019] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 5 This utility model provides a cold pressing device for Sichuan pepper oil, including a pressing cylinder 2, which is kept horizontally by a support 1; The pressing roller 9 is rotatably installed inside the pressing cylinder 2 to press the peppercorns inside the pressing cylinder 2 to extract oil and convey it to one end; The feed hopper 6 is located above one end of the pressing cylinder 2 and has a drying mechanism inside it; Oil receiving trough plate 4 is arranged at the bottom of the pressing cylinder 2; The slag discharge hopper 5 is located at the bottom of the pressing cylinder 2, away from the feed hopper 6.

[0020] In this embodiment, the two ends of the pressing cylinder 2 are mounted on the bracket 1 via connecting discs 3. The pressing roller 9 is rotatably disposed inside the pressing cylinder 2 via a rotating connector and one end extends to the outside of the pressing cylinder 2. It is connected to the drive motor 7 via a belt drive mechanism 8.

[0021] In this embodiment, the pressing cylinder 2 has a conical structure and oil discharge holes are evenly opened at the bottom. The feed hopper 6 is connected and disposed above the large end of the pressing cylinder 2. The pressing roller 9 has a spiral roller structure.

[0022] Furthermore, the pressing roller can be configured as a variable pitch screw to facilitate the pressing of Sichuan peppercorns.

[0023] In this embodiment, the air drying mechanism specifically includes an air inlet pipe 11 disposed on the side end of the feed hopper 6 and connected thereto, and a dispersing component disposed on the inner end of the feed hopper 6. There are two air inlet pipes 11 in total, which are disposed opposite to each other on both sides of the feed hopper 6.

[0024] In this embodiment, the dispersing component includes several dispersing rods 10 disposed on the inner side of the top of the feeding hopper 6 and a feeding baffle 14 disposed below the dispersing rods 10. The dispersing rods 10 are parallel and disposed at the same height to disperse the peppercorns into the feeding hopper 6. The feeding baffle 14 is rotatably disposed in the feeding hopper 6. The air inlet pipe 11 is disposed on the side wall of the feeding hopper 6 between the dispersing rods 10 and the feeding baffle 14.

[0025] As described above, when the peppercorns enter the feed hopper, they fall downwards through the gap of the dispersing rod, achieving initial dispersion. During the falling process, cold air blown out of the air inlet pipe comes into contact with the peppercorns, achieving the first air drying. Subsequently, the peppercorns fall and impact the feed baffle, achieving a second dispersion. The cold air from the air inlet pipe comes into contact with the peppercorns again, achieving a second air drying. Finally, the peppercorns fall through the gap between the feed baffle and the feed hopper into the pressing cylinder below for pressing.

[0026] Please see the appendix Figure 6 In this embodiment, the feed baffle 14 is an arc-shaped plate with a support rod 15 in the middle of the concave surface. The support rod 15 is rotatably mounted on the feed hopper 6 and extends one end to the outside of the feed hopper 6. A linear drive device 12 and a gear and rack transmission mechanism 13 are provided on the outer end of the feed hopper 6. The gear of the gear and rack transmission mechanism 13 is sleeved on the outside of the support rod 15, and its rack meshes with the gear and is driven by the linear drive device 12.

[0027] As mentioned above, the shape and drive control method of the feed baffle are set to adjust the feeding speed of the peppercorns, which facilitates pressing and oil extraction, and also to fix the feed baffle.

[0028] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
