Description

Technical Field

[0001] This utility model relates to the field of plant medicinal raw material extraction technology, and in particular to a low-temperature pressing machine for sea buckthorn seed oil. Background Technology

[0002] In the field of plant-based medicinal material extraction, low-temperature pressing technology has been widely used in the processing of various Chinese medicinal herbs and plant oils rich in heat-sensitive substances due to its excellent preservation of active ingredients. Sea buckthorn seed oil, as a functional plant oil with significant antioxidant, anti-inflammatory, and repairing effects, is widely used in the production of pharmaceutical preparations, health foods, and high-end topical ointments. To ensure that its key active ingredients are not destroyed during processing, low-temperature pressing is typically used for oil extraction from sea buckthorn seeds.

[0003] However, in actual production, uneven material supply and unstable temperature control often lead to low oil yield or fluctuating oil quality, affecting product stability and equipment production efficiency. Some pressing equipment struggles to balance oil extraction efficiency with low-temperature protection, easily causing oil deterioration or nutrient loss due to temperature increases during pressing, impacting the final product's quality and market value. Most low-temperature pressing equipment on the market lacks effective heat control mechanisms in its structural design. Especially during long-term continuous operation, the heat generated inside the pressing cylinder due to friction and pressure is difficult to dissipate in time, leading to localized overheating of the material and disrupting the basic conditions for low-temperature pressing.

[0004] Therefore, it is necessary to design a low-temperature pressing machine for sea buckthorn seed oil to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of some pressing equipment that cannot balance oil extraction efficiency and low temperature protection function, and that the oil quality is easily deteriorated or nutrients are lost due to temperature rise during the pressing process, and that most low temperature pressing equipment on the market lacks effective heat control means in its structural design, this utility model provides a low temperature pressing machine for sea buckthorn seed oil.

[0006] The technical solution is as follows: A low-temperature pressing machine for sea buckthorn seed oil includes a support frame, a pressing cylinder, a first servo motor, a spiral pressing roller, a filter plate, an oil storage tank, an oil outlet valve, and an arc-shaped heat dissipation fin assembly. The pressing cylinder is installed on the top of the support frame. A first servo motor with its output shaft facing left is installed on the right side of the pressing cylinder. A spiral pressing roller is fixedly connected to the output shaft. The spiral pressing roller is located inside the pressing cylinder and is rotatably connected to it. The space inside the spiral pressing roller and the pressing cylinder decreases from right to left to form a pressing chamber. A filter plate is provided at the bottom of the pressing cylinder. A slag outlet is provided at the lower left side of the pressing cylinder. An oil storage tank is fixedly connected to the lower part of the pressing cylinder. The oil storage tank and the pressing cylinder are connected through the filter plate. An oil outlet valve is provided at the lower right side of the oil storage tank. Arc-shaped heat dissipation fin assemblies are symmetrically fixedly connected to the upper periphery of the pressing cylinder.

[0007] As a further preferred option, transparent windows are also included, with transparent windows symmetrically opened on both the front and rear sides of the oil storage tank.

[0008] As a further preferred embodiment, it also includes a feeding pipe, a second servo motor, a screw feeder, and a feeding hopper. The upper right side of the pressing cylinder is fixedly connected to an inclined feeding pipe. The right end of the feeding pipe is equipped with a second servo motor with its output shaft facing left. Its output shaft extends into the feeding pipe and is fixedly connected to a screw feeder. The upper right side of the feeding pipe is connected to and communicates with a feeding hopper.

[0009] As a further preferred embodiment, it also includes a connecting shaft, a first bevel gear, a second bevel gear, and heat dissipation blades. The connecting shaft is rotatably connected between the tops of the front and rear sides of the pressing cylinder. Two first bevel gears are fixedly connected at intervals on the connecting shaft. Two transversely arranged second bevel gears are also rotatably connected between the tops of the front and rear sides of the pressing cylinder, respectively meshing with the first bevel gears at corresponding positions. Heat dissipation blades are fixedly connected to the bottom of each second bevel gear. All of the above components are located above the pressing cylinder and the arc-shaped heat dissipation fin assembly.

[0010] As a further preferred embodiment, it also includes a pulley assembly, wherein the left end of the output shaft of the first servo motor extends out of the left side of the pressing cylinder and is provided with a pulley assembly between it and the left end of the connecting shaft to form a transmission connection.

[0011] This invention has the following advantages: 1. By adopting a design where the internal space of the spiral oil pressing roller and the pressing cylinder gradually decreases from right to left, and combined with an arc-shaped heat dissipation fin group symmetrically fixedly connected to the front and rear of the upper periphery of the pressing cylinder, this invention achieves efficient extraction of sea buckthorn seed oil. This design not only improves the oil extraction rate, but also, in conjunction with an effective heat dissipation system, maintains a low-temperature operating environment, maximizing the preservation of nutrients in the sea buckthorn seed oil and improving product quality.

[0012] 2. This invention controls the speed and amount of material entering the pressing cylinder by setting a second servo motor to drive the screw feeder, thus achieving precise material supply. This method not only achieves quantitative supply but also ensures the stability and continuity of equipment operation, thereby improving production efficiency and helping to maintain consistent product quality.

[0013] 3. This utility model achieves effective heat dissipation and maintains low-temperature operating conditions by integrating heat dissipation blades driven by a first servo motor and an arc-shaped heat dissipation fin assembly on the outside of the pressing cylinder. This system not only rapidly dissipates the heat generated during the pressing process, keeping the equipment within a suitable operating temperature range, but also further ensures long-term stable operation and extends the equipment's service life.

Detailed Implementation

[0019] Example: A low-temperature pressing machine for sea buckthorn seed oil, such as Figures 1-4 As shown, the device includes a support frame 1, a pressing cylinder 2, a first servo motor 21, a spiral oil pressing roller 22, a filter plate 23, an oil storage tank 4, a transparent window 41, an oil outlet valve 5, and an arc-shaped heat dissipation fin assembly 6. The pressing cylinder 2 is mounted on top of the support frame 1. The first servo motor 21, with its output shaft facing left, is mounted on the right side of the pressing cylinder 2. The spiral oil pressing roller 22 is welded to the output shaft. The spiral oil pressing roller 22 is located inside the pressing cylinder 2 and is rotatably connected to it. The space inside the spiral oil pressing roller 22 and the pressing cylinder 2 decreases from right to left, causing the cross-sectional area of ​​the material channel to gradually decrease, forming a pressing chamber. The bottom of the pressing cylinder 2 is equipped with a filter plate 23. The pressing cylinder 2 and the filter plate 23 are made of medical-grade stainless steel to ensure drug safety and easy cleaning and maintenance. The lower left side of the pressing cylinder 2 is equipped with a slag outlet 24. The lower part of the pressing cylinder 2 is connected to an oil storage tank 4 by bolts. The oil storage tank 4 has transparent windows 41 symmetrically opened on both the front and rear sides to facilitate observation of the oil storage. The oil storage tank 4 is connected to the pressing cylinder 2 through the filter plate 23. The lower right side of the oil storage tank 4 is equipped with an oil outlet valve 5. The upper outer periphery of the pressing cylinder 2 is symmetrically connected to an arc-shaped heat dissipation fin group 6 by bolts to improve the heat dissipation efficiency of the surface of the pressing cylinder 2.

[0020] like Figures 1-4As shown, it also includes a feeding pipe 31, a second servo motor 32, a spiral feeding rod 33, and a feeding hopper 3. The upper right side of the pressing cylinder 2 is connected to the inclined feeding pipe 31 by bolts. The right end of the feeding pipe 31 is equipped with a second servo motor 32 with its output shaft facing to the left. Its output shaft extends into the feeding pipe 31 and is connected to the spiral feeding rod 33 by welding. The upper right side of the feeding pipe 31 is connected to and communicates with the feeding hopper 3 for quantitative supply of materials.

[0021] like Figures 1-4 As shown, it also includes a pulley assembly 7, a connecting shaft 8, a first bevel gear 9, a second bevel gear 10, and heat dissipation blades 11. The left end of the output shaft of the first servo motor 21 extends out of the left side of the pressing cylinder 2, and a pulley assembly 7 is provided between it and the left end of the connecting shaft 8 to form a transmission connection, transmitting power to the connecting shaft 8 and driving the heat dissipation device to operate synchronously. The connecting shaft 8 is rotatably connected between the tops of the front and rear sides of the pressing cylinder 2. Two first bevel gears 9 are connected to the connecting shaft 8 at intervals by bolts. Two horizontally arranged second bevel gears 10 are also rotatably connected between the tops of the front and rear sides of the pressing cylinder 2, respectively, and mesh with the first bevel gears 9 at corresponding positions. Each second bevel gear 10 has a heat dissipation blade 11 connected to its bottom by bolts. The heat dissipation blades 11 are all located above the pressing cylinder 2 and the arc-shaped heat dissipation fin assembly 6, forming an auxiliary air cooling structure.

[0022] Before operating the seabuckthorn seed oil cryogenic press, first ensure that all components are in normal working condition and that the oil storage tank 4 and the slag outlet 24 are clean. After starting the equipment, the operator first needs to feed the seabuckthorn seeds into the equipment through the feed hopper 3. These seabuckthorn seeds will slide into the equipment along the inclined feed pipe 31. During this process, the second servo motor 32 drives the screw feed rod 33 to rotate, which not only helps the material fall smoothly, but also controls the speed and amount of material entering the pressing cylinder 2, achieving quantitative supply.

[0023] As sea buckthorn seeds are gradually fed into the pressing cylinder 2, the first servo motor 21 starts working, its output shaft extending to the left and driving the spiral oil pressing roller 22 to rotate. The space between the spiral oil pressing roller 22 and the wall of the pressing cylinder 2 gradually decreases from right to left. Inside the pressing chamber, as the spiral oil pressing roller 22 rotates, the sea buckthorn seeds are gradually pushed towards the smaller end of the spiral oil pressing roller. Because the spiral oil pressing roller has a spiral structure, the space of the spiral groove gradually decreases, and the squeezing pressure on the sea buckthorn seeds gradually increases, thereby squeezing out the oil. The sea buckthorn seed residue after pressing is discharged through the slag outlet 24 at the lower left side of the pressing cylinder 2, while the extracted sea buckthorn seed oil is preliminarily filtered through the filter plate 23 at the bottom to remove impurities. The filtered oil flows into the oil storage tank 4 located below the pressing cylinder 2. The operator can observe the oil storage situation at any time through the transparent window 41 and collect the sea buckthorn seed oil by opening the oil outlet valve 5.

[0024] Meanwhile, to maintain optimal equipment operation, the power of the first servo motor 21 is transmitted to the connecting shaft 8 via the pulley assembly 7, causing the first bevel gear 9 on the connecting shaft 8 to rotate. This, in turn, drives the meshing second bevel gear 10 to rotate. Each second bevel gear 10 has a heat dissipation fin 11 fixed to its bottom. The rotation of these heat dissipation fins 11 generates airflow, which, with the help of the arc-shaped heat dissipation fin assembly 6, effectively dissipates the heat generated by the pressing cylinder 2, maintaining stable equipment operating conditions. The arc-shaped heat dissipation fin assembly 6 not only increases the surface area and improves heat dissipation efficiency but also helps maintain a temperature range conducive to preserving the nutrients of sea buckthorn seed oil.

[0025] The entire process, from material input, pressing, oil residue separation to final oil collection, is carried out efficiently and continuously under an automated control system. This not only improves production efficiency but also ensures the quality of the final product. The low-temperature press for sea buckthorn seed oil achieves effective processing of sea buckthorn seeds and produces high-quality sea buckthorn seed oil.
