Description

Technical Field

[0001] This invention relates to modern agriculture, and in particular to a crop grain processing device, belonging to the field of new equipment technology. Background Technology

[0002] With the continuous upgrading of people's health consumption concepts, low-fat, natural, and nutritious snack foods have become the mainstream market demand. As a unique nut with both edible and medicinal value, Trichosanthes kirilowii seeds, rich in amino acids, minerals, and unsaturated fatty acids, have seen their market demand rise year by year. Optimizing and upgrading its deep processing technology has become a core focus for promoting the high-quality development of the Trichosanthes kirilowii industry. Undefatted Trichosanthes kirilowii seeds have a high natural fat content, and the oil is prone to oxidative rancidity during storage. This not only shortens the product's shelf life and affects food safety but also fails to meet the production requirements of deep-processed products such as protein extraction, low-fat snacks, and functional beverages. Therefore, defatting of Trichosanthes kirilowii seeds has become an indispensable key process before making snacks and deep-processed products. Currently, the industry commonly uses Trichosanthes kirilowii seed degreasing equipment to complete the above-mentioned degreasing process. Most existing degreasing equipment employs a combination of high-temperature baking and constant-pressure extrusion. The specific operation process is as follows: first, the shelled Trichosanthes kirilowii seeds undergo high-temperature baking pretreatment to reduce the viscosity of the internal oil in the seeds; then, two opposing extrusion discs within the device apply constant pressure to the seeds, forcing the oil out of the seeds, thus achieving the degreasing purpose. This process is widely used in small and medium-sized Trichosanthes kirilowii seed processing enterprises due to its simple structure and low cost. However, in actual large-scale production, the particle size of Trichosanthes kirilowii seeds naturally varies due to factors such as variety, planting environment, and pretreatment, typically ranging from 1.5mm to 2.0mm. When using the existing degreasing device, the pressure applied by the extrusion disc is a fixed value and cannot be adaptively adjusted according to the differences in the size of the Trichosanthes kirilowii seeds. This results in uneven surface pressure on seeds of different sizes, with larger seeds receiving significantly greater surface pressure than smaller ones. Consequently, larger seeds are more prone to shell breakage and seed fragmentation due to excessive pressure, reducing product appearance and commercial value. Conversely, smaller seeds, due to insufficient pressure, fail to fully extract the internal oil, resulting in excessively high residual oil content. This affects product taste and shelf life, restricts the quality of subsequent deep processing, and ultimately impacts the overall quality and market competitiveness of the finished Trichosanthes kirilowii seed product. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the prior art and to provide a degreasing device for Trichosanthes kirilowii seeds.

[0004] To achieve the objective of this invention, the following technical solution is adopted: a degreasing device for Trichosanthes kirilowii seeds, comprising a housing and a baking device, wherein the baking device is disposed inside the housing, and the baking section is used to heat the Trichosanthes kirilowii seeds, and further comprising: An upper conical disc is connected to the machine housing. The upper conical disc is vertically arranged with its cone tip pointing upwards. A feed inlet is provided at the cone tip of the upper conical disc. A first elastic pad is fixedly provided on the inner conical surface of the upper conical disc. The lower end surface of the first elastic pad is a conical surface with the same degree as the upper conical disc. A lower conical disk is disposed below the upper conical disk. The lower conical disk and the upper conical disk are coaxial and in the same direction. A second elastic pad is fixedly disposed on the outer conical surface of the lower conical disk. The upper end surface of the second elastic pad is a conical surface with the same degree as the lower conical disk. The upper end surface of the second elastic pad is a conical surface. The cone half angle of the lower end surface of the first elastic pad is smaller than the cone half angle of the second elastic pad. There is a gap between the lower end surface of the first elastic pad and the upper end surface of the second elastic pad. The vibration mechanism has its actuating end fixedly connected to the lower end of the lower conical disk. The vibration mechanism is used to drive the lower conical disk to vibrate in the vertical direction. During the vibration of the lower conical disk, when the lower conical disk is closest to the upper conical disk, the distance between the inner edge of the lower end face of the first elastic pad and the upper end face of the second elastic pad is greater than 2.5 mm and less than 3 mm, and the distance between the outer edge of the lower end face of the first elastic pad and the upper end face of the second elastic pad is greater than 0.5 mm and less than 1 mm.

[0005] Furthermore, a separation mechanism is provided below the lower conical disc. This separation mechanism is used to separate Trichosanthes kirilowii seeds that have not reached a predetermined level of defatting. The separation mechanism is connected to a suction mechanism, which is used to suck the Trichosanthes kirilowii seeds that have not reached a predetermined level of defatting into the feed inlet on the upper conical disc. The separation mechanism includes a first receiving hopper, a blower, a second receiving hopper, and a receiving trough. The first receiving hopper is located below the lower conical disc and is used to receive Trichosanthes kirilowii seeds that slide down from the outer edge of the lower conical disc. The blower is located inside the funnel opening of the first receiving hopper. The second receiving hopper is located below the fan and coaxially with the first receiving hopper. The receiving trough is located on the outside of the second receiving hopper. Under the action of the wind force of the scattered wind and the gravity of the Trichosanthes kirilowii seeds, the Trichosanthes kirilowii seeds that have not reached the predetermined degree of defatting fall into the receiving trough on the outside of the second receiving hopper. The suction mechanism is connected to the receiving trough. The separation mechanism is used to separate the Trichosanthes kirilowii seeds that have not reached the predetermined degree of defatting. The suction mechanism is used to suck the Trichosanthes kirilowii seeds that have not reached the predetermined degree of defatting into the feed port on the upper conical plate.

[0006] Furthermore, a threaded rod is connected to the blower, the threaded rod is vertically arranged, and a first nut is connected to the side wall of the receiving hopper two. The first nut is connected to the threaded rod, and rotating the first nut can adjust the vertical distance between the top of the receiving hopper two and the blower.

[0007] Furthermore, a fixed plate is fixedly connected inside the housing, and the fixed plate has a vertical sliding hole. A vertically arranged sliding tube is fixedly connected to the feed inlet of the upper conical plate. The sliding tube communicates with the feed inlet. The outer wall of the sliding tube has an external thread and a vertical limiting groove. A limiting slider is slidably connected in the limiting groove. The limiting slider is fixed in the sliding hole. A second nut is connected to the outer wall of the sliding tube through the external thread. The second nut is rotatably connected to the fixed plate. Rotating the second nut can adjust the distance between the outer edge of the lower end face of the first elastic pad and the upper end face of the second elastic pad.

[0008] Furthermore, an oil receiving ring groove is provided on the lower side of the outer edge sidewall of the lower conical disk. The oil receiving ring groove is used to receive grease flowing from the lower conical disk. The oil receiving ring groove is coaxially arranged with the lower conical disk. The lower end of the sidewall of the lower conical disk is inclined towards its own axis. The outer edge diameter of the oil receiving ring groove is smaller than the lower end diameter of the sidewall of the lower conical disk.

[0009] Furthermore, the baking device includes a gas heater and a heating pad. The gas heater is located inside the fan and is used to heat the diffused air generated by the fan. The heating pad is fixedly installed on the outer conical surface of the lower conical disk and is used to heat the second elastic pad.

[0010] Furthermore, the cone half-angle of the second elastic pad is greater than 75 degrees and less than 85 degrees.

[0011] Furthermore, the upper end of the receiving hopper is fixedly connected to the lower end of the lower conical disc.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The trichosanthes seed degreasing device of the present invention involves feeding pre-treated roasted trichosanthes seeds through the feed inlet at the tip of the upper conical disc, allowing them to flow to the tip of the lower conical disc and slide down along the upper surface of the second elastic pad. Driven by a vibration mechanism, the lower conical disc vibrates at high frequency, and the second elastic pad vibrates vertically back and forth, causing the trichosanthes seeds to enter the gap channel between the lower surface of the first elastic pad and the upper surface of the second elastic pad, and move towards the outer edge of the second elastic pad. When the lower conical disc moves downwards, the gap increases, facilitating the even contact and tumbling of the trichosanthes seeds; when it moves upwards, the gap decreases, squeezing the trichosanthes seeds and causing the oil to seep out. Because the cone half-angle of the lower end face of the first elastic pad is smaller than that of the second elastic pad, the gap channel gradually narrows from wide at the top to narrow at the bottom. Different sizes of Trichosanthes kirilowii seeds have different thicknesses. As larger seeds are compressed, oil seeps out, causing the seeds to gradually shrink and decrease in thickness. This results in a relatively uniform thickness of seeds at the same cross-sectional position on the second elastic pad, ensuring a more balanced compressive force on the seeds at different locations. This reduces the probability of seed breakage while ensuring sufficient degreasing. The separation mechanism detects and separates the seeds to determine their degreasing level, screening out those that haven't reached the predetermined level. The suction mechanism smoothly draws these substandard seeds into the feed inlet of the upper conical disc, where they re-enter the gap between the first and second elastic pads for secondary compression degreasing, thus preventing incomplete degreasing.

[0021] like Figures 1-6 As shown, the degreasing device for Trichosanthes kirilowii seeds provided by the present invention includes a housing 101 and a baking section 102. The baking section 102 is disposed inside the housing 101 and is used to heat the Trichosanthes kirilowii seeds. It also includes an upper conical disc 103, a lower conical disc 106, and a vibration mechanism 108. The upper conical disc 103 is connected to the housing 101, is vertically arranged with its tip pointing upwards, and has a feed inlet 104 at its tip. A first elastic pad 105 is provided on the inner conical surface of the upper conical disc 103, and the lower end surface of the first elastic pad 105 is a conical surface. The lower conical disc 106 is disposed below the upper conical disc 103, is coaxial with and in the same direction as the upper conical disc 103, and has a second elastic pad 108 on its outer conical surface. 07. The upper end face of the second elastic pad 107 is a conical surface. The cone half angle of the lower end face of the first elastic pad is smaller than that of the second elastic pad. A gap is left between the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107. The vibration mechanism 108 is connected to the lower end of the lower conical disk 106. The vibration mechanism 108 is used to drive the lower conical disk 106 to vibrate in the vertical direction. During the vibration of the lower conical disk 106, when the lower conical disk 106 is closest to the upper conical disk 103, the distance between the inner edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 2.5mm and less than 3mm, and the distance between the outer edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 0.5mm and less than 1mm.

[0022] The working principle of the above embodiments is briefly described below: The housing 101 of this device provides a sealed processing space for the overall structure. The baking section 102 heats and pre-treats the shelled Trichosanthes kirilowii seeds to reduce the viscosity of the oil inside the seeds, creating conditions for subsequent degreasing. The upper conical disk 103 and the lower conical disk 106 are arranged coaxially and in the same direction. The cone half-angle of the lower conical disk 106 is greater than 75 degrees and less than 85 degrees. A degreasing channel is formed through the gap between the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107. The first elastic pad 105 and the second elastic pad 107 form a buffer protective layer to avoid hard contact damage to the Trichosanthes kirilowii seeds. The vibration mechanism 108 drives the lower conical disk 106 to vibrate vertically. Through the squeezing action, the oil inside the Trichosanthes kirilowii seeds seeps out. At the same time, the gap range is precisely controlled so that the distance between the outer edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 0.5 mm and less than 1 mm, ensuring the degreasing effect while preventing damage to the shape.

[0023] The vibration mechanism 108 provides high-frequency vertical vibration to the lower conical disk 106. Through precise setting of amplitude and vibration frequency, a gradient-increasing physical extrusion force is formed between the first elastic pad 105 and the second elastic pad 107. From the inner edge of the gap channel where the Trichosanthes kirilowii seeds enter to the outer edge where they slide out, the extrusion force gradually increases from 0.3MPa to 0.8MPa, which is adapted to the state of the Trichosanthes kirilowii seeds gradually becoming deflated. The specific parameters are as follows: The rated vibration frequency of the vibration mechanism 108 is 3Hz~5Hz. This frequency can ensure that the Trichosanthes kirilowii seeds roll evenly in the gap channel and avoid accumulation, and can also make the extrusion force act evenly on the surface of the Trichosanthes kirilowii seeds to prevent local pressure sudden changes from causing damage. The vertical vibration amplitude of the vibration mechanism 108 is 3mm ± 0.5mm. This amplitude is precisely matched with the gap range (2.5mm~3mm on the inner edge and 0.5mm~1mm on the outer edge) of the first elastic pad 105 and the second elastic pad 107, ensuring that the gap decreases uniformly when the lower conical disc 106 moves upward, forming a gradient extrusion force, and the gap increases uniformly when it moves downward, which facilitates the rolling of the Trichosanthes kirilowii seeds and the exudation of oil. The vibration force of the vibration mechanism 108 has a distribution error of ≤±5% on the bottom surface of the lower conical disk 106, ensuring that the vibration amplitude of each position of the second elastic pad 107 is consistent and avoiding uneven local pressure in the gap channel.

[0024] The gradually increasing physical extrusion pressure on the Trichosanthes kirilowii seeds is achieved through the combined effects of the vibration mechanism's amplitude / frequency, the material and specifications of the elastic pads, and the gradually contracting structure of the gap channels. Both the first elastic pad 105 and the second elastic pad 107 are made of food-grade nitrile rubber (with further subdivision of rubber materials to improve compatibility), with a thickness of 4mm ± 0.5mm, an elastic modulus of 2.5MPa ± 0.3MPa, and a Shore hardness of 60 ± 3HA. This specification of the first elastic pad 105 and the second elastic pad 107 matches the vibration mechanism's amplitude of 3mm ± 0.5mm and its frequency of 3Hz to 6Hz. During the extrusion process, the first elastic pad 105 and the second elastic pad 107 undergo elastic deformation, buffering the hard contact, while simultaneously increasing the extrusion pressure gradually from 0.3MPa ± 0.05MPa at the inner edge to 0.8MPa ± 0.05MPa at the outer edge. When the conical disc 106 moves to its uppermost position, the distance between the inner edge of the first elastic pad 105 and the second elastic pad 107 is 2.8mm ± 0.2mm, corresponding to a compressive force of 0.3MPa ± 0.05MPa; the distance at the middle position is 1.5mm ± 0.2mm, corresponding to a compressive force of 0.5MPa ± 0.05MPa; and the distance at the outer edge is 0.8mm ± 0.2mm, corresponding to a compressive force of 0.8MPa ± 0.05MPa, forming a continuous gradient compressive force that adapts to the degreasing process of Trichosanthes kirilowii seeds from an intact state to gradually becoming shriveled. Considering the natural particle size difference of Trichosanthes kirilowii seeds (1.5mm ~ 2.0mm), the combination of the above vibration parameters, elastic pad parameters, and gap parameters ensures that the surface pressure deviation of Trichosanthes kirilowii seeds of different sizes is ≤ ± 0.08MPa, ensuring balanced pressure and reducing the probability of seed breakage during the degreasing process.

[0025] This device employs a method for defatting Trichosanthes kirilowii seeds using a low-temperature cold extraction process. The temperature of the baking section and the overall defatting environment is controlled within the range of 45℃±5℃ to 80℃±5℃ throughout the process. This temperature range is the optimal range for low-temperature defatting of Trichosanthes kirilowii seeds, which reduces the viscosity of the internal oil and improves its fluidity for efficient defatting. It also prevents the destruction of nutrients (amino acids, unsaturated fatty acids, etc.) caused by high temperatures, and prevents the seed shell from becoming brittle and breaking during extrusion. Before feeding the seeds, the heating pad 7 in the baking section is preheated to 45℃±3℃, and the gas heater inside the blower 302 heats the diffused air to 70℃±3℃, creating a stable low-temperature thermal environment inside the casing 101. During the extrusion and degreasing stage of Trichosanthes kirilowii seeds, the internal temperature of the casing 101 is maintained at 75℃±5℃, the heating temperature of the heating pad 7 on the second elastic pad 107 is 68℃±3℃, and the temperature of the diffused air is maintained at 70℃±3℃, ensuring that the oil maintains a low viscosity at low temperatures while preventing the Trichosanthes kirilowii seeds from being overheated. The temperature sensor in the baking section (with newly added matching sensing components) has a temperature monitoring error of ≤±2℃ for each heating unit, achieving precise temperature control and preventing localized high or low temperatures from affecting the degreasing effect. The shelled Trichosanthes kirilowii seeds to be defatted are fed into the machine casing 101. The baking section 102 is started, and the baking temperature is adjusted according to the variety and moisture content of the Trichosanthes kirilowii seeds. The seeds are heated until the outer skin is slightly dry and the viscosity of the internal oil is reduced without damaging the nutrients. This facilitates oil seepage while avoiding the destruction of nutrients due to high temperature. The position of the upper conical plate 103 is adjusted to ensure that its coaxiality with the lower conical plate 106 meets the standard. The integrity of the first elastic pad 105 and the second elastic pad 107 is checked to ensure good elasticity, a flat surface, and no damage or bulges, avoiding uneven local pressure. Calibration is then performed. The vibration frequency and amplitude of the vibration mechanism 108 are set to ensure that during the vibration of the lower conical disk 106, when the lower conical disk 106 is closest to the upper conical disk 103, the distance between the outer edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 0.5mm and less than 1mm, and the distance between the inner edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 2.5mm and less than 3mm. This gap can effectively compress the seeds of Trichosanthes kirilowii and adapt to their particle size differences, reserving elastic buffer space. After being pre-treated by baking, the Trichosanthes seeds are fed into the feed port 104 at the tip of the upper conical disk 103, and then flow to the tip of the lower conical disk 106. Under the action of gravity, they slide down along the upper end surface of the second elastic pad 107. Driven by the vibration mechanism 108, the lower conical disk 106 vibrates at a high frequency, and the second elastic pad 107 reciprocates in the vertical direction. The Trichosanthes seeds enter the gap channel between the lower end surface of the first elastic pad 105 and the upper end surface of the second elastic pad 107, and with the high-frequency vibration of the second elastic pad 107, the Trichosanthes seeds gradually move towards the outer edge of the second elastic pad 107. As the conical disc 106 moves downwards, the gap increases, facilitating the downward rolling of the Trichosanthes kirilowii seeds. This ensures that each seed makes uniform contact with the surface of the second elastic pad 107, preventing localized accumulation. Conversely, as the conical disc 106 moves upwards, the gap between the second elastic pad 107 and the first elastic pad 105 decreases, gradually compressing the seeds on the second elastic pad 107. The thickness of Trichosanthes kirilowii seeds varies depending on their size (shelled seeds are generally flat and elliptical, with a thickness of 1.5mm–2.0mm, a pointed tip, and a blunt, rounded base). As larger seeds are compressed, oil seeps out, causing the seeds to gradually deflate and decrease in thickness. This results in a relatively uniform thickness of seeds at the same cross-sectional position on the second elastic pad 107. The taper of the lower end face of the first elastic pad 105 is smaller than the taper of the upper end face of the second elastic pad 107, and the gap channel gradually contracts from top to bottom. In the current state, when the lower conical disk 106 moves upward to its uppermost position (i.e., when the lower conical disk 106 is closest to the upper conical disk 103), the distance between the inner edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 2.5 mm and less than 3 mm, and the distance between the outer edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 is greater than 0.5 mm and less than 1 mm. This ensures that the squeezing force on the Trichosanthes kirilowii seeds at different positions on the second elastic pad 107 is relatively balanced. Therefore, the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107 can apply a relatively uniform squeezing force to Trichosanthes kirilowii seeds of different particle sizes, so that the surface pressure of the Trichosanthes kirilowii seeds is approximately between 0.3 MPa and 0.8 MPa. This ensures the degreasing efficiency of the Trichosanthes kirilowii seeds while preventing them from being crushed, broken, or severely deformed due to excessive pressure. After defatting, the Trichosanthes kirilowii seeds are discharged from the bottom of the lower conical plate 106. After subsequent cleaning and cooling, the defatted Trichosanthes kirilowii seeds can be obtained.

[0026] The degreasing device for Trichosanthes kirilowii seeds of the present invention, by designing that the taper of the lower end face of the first elastic pad 105 is smaller than the taper of the upper end face of the second elastic pad 107 (the cone half angle of the lower end face of the first elastic pad is smaller than the cone half angle of the second elastic pad), can adapt to Trichosanthes kirilowii seeds that become shriveled due to gradual degreasing. This ensures that Trichosanthes kirilowii seeds of different sizes are subjected to relatively balanced surface pressure throughout the degreasing process, thereby reducing the probability of seed breakage while ensuring sufficient degreasing.

[0027] Based on the above embodiments, in order to prevent insufficient defatting of Trichosanthes seeds, such as... Figures 2-5 As shown, a separation mechanism 201 is provided below the lower conical disk 106. The separation mechanism 201 is used to separate the Trichosanthes kirilowii seeds that have not reached the predetermined degree of defatting. The separation mechanism 201 is connected to a suction mechanism 202, which is used to suck the Trichosanthes kirilowii seeds that have not reached the predetermined degree of defatting into the feed inlet 104 on the upper conical disk 103.

[0028] A separation mechanism 201 is installed below the lower conical disc 106 to ensure that it can accurately receive all the Trichosanthes kirilowii seeds discharged from the outer edge of the lower conical disc 106. The separation mechanism 201 and the suction mechanism 202 are connected in a sealed manner. The suction force of the suction mechanism 202 is calibrated to ensure that the Trichosanthes kirilowii seeds that do not meet the standards can be sucked up smoothly without damaging their shape. The degreasing standard is preset (according to the requirements of the finished product, the oil content of the degreased Trichosanthes kirilowii seeds can be set to ≤5% to meet the standard). The separation accuracy of the separation mechanism 201 is adjusted to ensure that the standard and the non-standard Trichosanthes kirilowii seeds can be accurately distinguished. During operation, the Trichosanthes kirilowii seeds discharged from the lower conical disc 106 enter the separation mechanism 201. The separation mechanism 201 detects and separates the degree of degreasing, and screens out the Trichosanthes kirilowii seeds that have not reached the predetermined degree of degreasing. The suction mechanism 202 smoothly sucks the substandard Trichosanthes kirilowii seeds into the feed inlet 104 of the upper conical disc 103, and re-enters the gap between the first elastic pad 105 and the second elastic pad 107 for secondary compression degreasing, thereby preventing insufficient degreasing of Trichosanthes kirilowii seeds.

[0029] As a preferred option, such as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the separation mechanism 201 includes a first receiving hopper 301, a fan 302, a second receiving hopper 303, and a receiving trough 304. The first receiving hopper 301 is coaxially arranged with the lower conical disk 106, and is located below and coaxial with the lower conical disk 106. The first receiving hopper 301 is used to receive the Trichosanthes kirilowii seeds sliding down from the outer edge of the lower conical disk 106. The fan 302 is located inside the funnel opening of the first receiving hopper 301. The blower 302 generates a radially diffused airflow along the receiving hopper 301. The receiving hopper 303 is located below the blower 302 and coaxially arranged with the receiving hopper 301. The receiving trough 304 is located on the outside of the receiving hopper 303. Under the influence of the diffused airflow and the gravity of the Trichosanthes kirilowii seeds, Trichosanthes kirilowii seeds that have not reached the predetermined degreasing level fall into the receiving trough 304 on the outside of the receiving hopper 303. The suction mechanism 202 is connected to the receiving trough 304. The receiving hopper 301 is coaxially fixed to the lower conical disk 106 to ensure that it can fully receive the Trichosanthes kirilowii seeds sliding down the outer edge of the lower conical disk 106 without any leakage. Install the blower 302 inside the funnel opening of receiving hopper 1 301, and calibrate the wind speed of the blower 302 to generate a uniformly diffused wind along the radial direction of receiving hopper 1 301. The wind speed should be controlled between 2m / s and 3m / s (to accommodate the weight differences of the Trichosanthes kirilowii seeds). Place receiving hopper 2 303 coaxially below the blower 302 and adjust its position to ensure that substandard Trichosanthes kirilowii seeds can fall accurately into it. The suction mechanism 202 is sealed and connected to the funnel opening of receiving hopper 2 303. After defatting, the Trichosanthes kirilowii seeds slide from the lower conical disc 106 into the receiving hopper 301. Under their own gravity, they move towards the funnel opening of the receiving hopper 301. At this time, the scattered wind generated by the fan 302 exerts a radial thrust on the Trichosanthes kirilowii seeds falling from the funnel opening of the receiving hopper 301, moving away from the axis of the receiving hopper 301. The defatted Trichosanthes kirilowii seeds have more oil seepage, greater deformation, and higher density. Under the combined action of wind force and gravity, they... The seeds that move radially along the receiving hopper 301 travel a shorter distance, allowing them to fall into the receiving hopper 303 directly below it. In contrast, seeds that haven't reached the required degreasing level, due to less oil seepage, smaller deformation, and lower density, move a longer radial distance along the receiving hopper 301 under the combined influence of wind and gravity, falling into the receiving trough 304 outside the receiving hopper 303. They are then sucked by the suction mechanism 202 to the inlet 104 for secondary degreasing. This weight difference allows for precise separation of seeds with different degreasing levels, preventing breakage when screening for less degreased seeds and ensuring thorough degreasing during the final degreasing process.

[0030] As a preferred option, such as Figure 2As shown, a threaded rod 401 is connected to the blower 302, and the threaded rod 401 is vertically arranged. A first nut 402 is connected to the side wall of the receiving hopper 2 303. The first nut 402 is connected to the threaded rod 401. Rotating the first nut 402 can adjust the vertical distance between the top of the receiving hopper 2 303 and the blower 302. When the degreasing standard of the Trichosanthes kirilowii seeds is low, rotating the first nut 402 forward reduces the distance between the receiving hopper 1 301 and the receiving hopper 2 303, shortening the path of the Trichosanthes kirilowii seeds falling from the funnel opening of the receiving hopper 1 301, so that even Trichosanthes kirilowii seeds with a lower degree of degreasing can fall into the receiving hopper 2 303. When the degreasing standard of Trichosanthes kirilowii seeds is high, reverse the first nut 402 to increase the distance between receiving hopper one 301 and receiving hopper two 303, lengthening the path of the Trichosanthes kirilowii seeds falling from the funnel opening of receiving hopper one 301. This allows even highly degreased Trichosanthes kirilowii seeds to fall into the receiving trough 304 for secondary degreasing. By setting the first nut 402 and the threaded rod 401, the distance between receiving hopper two 303 and receiving hopper one 301 can be adjusted, thus flexibly adjusting the degree of degreasing of Trichosanthes kirilowii seeds according to requirements.

[0031] As a preferred option, such as Figure 2 and Figure 3 As shown, a fixed plate 501 is fixedly connected inside the housing 101. The fixed plate 501 has a vertical sliding hole. A vertically arranged sliding tube 502 is fixedly connected to the feed inlet 104 of the upper conical plate 103. The sliding tube 502 communicates with the feed inlet 104. The outer wall of the sliding tube 502 has an external thread and a vertical limiting groove 503. A limiting slider 504 is slidably connected inside the limiting groove 503. The limiting slider 504 is fixed inside the sliding hole. A second nut 505 is connected to the outer wall of the sliding tube 502 through an external thread. The second nut 505 is rotatably connected to the fixed plate 501. Rotating the second nut 505 can adjust the distance between the outer edge of the lower end face of the first elastic pad 105 and the upper end face of the second elastic pad 107. Rotating the second nut 505 prevents the slide tube 502 from rotating due to the guiding and limiting effect of the limiting slider 504 and the limiting groove 503. The slide tube 502 can only move vertically up and down, thereby driving the upper conical disk 103 to move synchronously up and down. This adjusts the distance between the outer edge of the lower end face of the first elastic pad 105 and the outer edge of the upper end face of the second elastic pad 107. This design allows for flexible adjustment of the extrusion gap based on the thickness and variety of the Trichosanthes kirilowii seeds, adapting to the degreasing requirements of different specifications of seeds. It ensures that the extrusion pressure is always maintained between 0.3MPa and 0.8MPa, guaranteeing thorough degreasing while preventing breakage.

[0032] As a preferred option, such as Figure 2As shown, the lower side of the outer edge of the lower conical disk 106 is provided with an oil receiving ring groove 6. The oil receiving ring groove 6 is used to receive grease flowing from the lower conical disk 106. The oil receiving ring groove 6 is coaxially arranged with the lower conical disk 106. The lower end of the side wall of the lower conical disk 106 is inclined towards its own axis to form an inward inclined surface 8, as shown. Figure 6 As shown, in the vertical direction, the lower edge of the inclined surface is located inside the oil-receiving ring groove, and the outer edge of the inclined surface is located outside the oil-receiving ring groove. The oil that seeps out from the Trichosanthes kirilowii seeds in the degreasing channel will slide down the surface of the second elastic pad 107 to the side wall of the lower conical disk 106. Since the lower end of the side wall of the lower conical disk 106 is inclined, the oil will flow along the side wall into the oil-receiving ring groove 6, realizing the concentrated collection of oil, thereby preventing oil from dripping into the receiving hopper 301 and affecting the normal separation of Trichosanthes kirilowii seeds, ensuring the full degreasing of Trichosanthes kirilowii seeds. In addition, the outer diameter of the oil-receiving ring groove 6 is smaller than the lower end diameter of the side wall of the lower conical disk 106, which can prevent Trichosanthes kirilowii seeds from falling into the oil-receiving ring groove 6 and hindering the separation of Trichosanthes kirilowii seeds.

[0033] As a preferred option, such as Figure 2 and Figure 6 As shown, the baking section 102 includes a gas heater and a heating pad 7. The gas heater is located inside the fan 302 and is used to heat the diffused air generated by the fan 302. The heating pad 7 is located on the outer conical surface of the lower conical disk 106 and is used to heat the second elastic pad 107. The gas heater is integrated into the blower 302 to ensure that it can evenly heat the diffused air generated by the blower 302. The heating temperature can be synchronously adapted to the temperature of the baking section 102 (60℃-80℃). The heated air can raise the overall temperature of the inner cavity of the casing 101, so that the Trichosanthes seeds are in a higher ambient temperature throughout the degreasing process, which improves the fluidity of the Trichosanthes seeds and the oil that has been separated. The heating pad 7 is attached and fixed to the outer conical surface of the lower conical plate 106 to ensure that the heating pad 7 and the second elastic pad 107 are in close contact, and the heating is uniform. This further reduces the viscosity of the internal oil, promotes the rapid and full seepage of oil, improves the degreasing efficiency, and avoids high temperature damage to the nutritional components of the Trichosanthes seeds, thus achieving both efficient degreasing and quality assurance.

[0034] As a preferred option, such as Figure 2 As shown, the cone half-angle of the second elastic pad 107 is greater than 75 degrees and less than 85 degrees. The cone half-angle of 75-85 degrees makes the upper end face of the second elastic pad 107 tilt at a moderate angle, which can guide the Trichosanthes kirilowii seeds to move slowly to the outside of the downward conical disk 106 under the action of the vibration mechanism 108, avoiding uneven compression caused by excessive movement, and also making the extrusion pressure evenly distributed along the surface of the Trichosanthes kirilowii seeds, ensuring that the oil seeps out evenly from all parts, while avoiding local pressure concentration that could cause the Trichosanthes kirilowii seeds to break.

[0035] As a preferred option, such as Figure 2 and Figure 6 As shown, both the first elastic pad 105 and the second elastic pad 107 are made of rubber. The rubber first elastic pad 105 and the second elastic pad 107 have a better cushioning effect, effectively absorbing the squeezing impact and preventing the seeds from being crushed or damaged due to hard contact. At the same time, the rubber first elastic pad 105 and the second elastic pad 107 have moderate friction, which can move the seeds with vibration without causing them to get stuck or be over-squeezed due to excessive friction.

[0036] As a preferred option, such as Figure 2 and Figure 4 As shown, the upper end of the receiving hopper 301 is fixedly connected to the lower end of the lower conical disk 106. By fixing the receiving hopper 301 to the lower conical disk 106, the lower conical disk 106 can drive the receiving hopper 301 to vibrate when the vibration mechanism 108 vibrates, thereby preventing the Trichosanthes seeds in the receiving hopper 301 from adhering to the inner wall of the receiving hopper 301, thus ensuring the normal separation of the Trichosanthes seeds.
