Abstract
Description
Technical Field
[0001] This application relates to the field of high-temperature extraction technology of vegetable oils, specifically a high-temperature extraction tank for extracting natural vegetable oils. Background Technology
[0002] Due to their wide range of nutritional, medicinal, and industrial value, the efficient and environmentally friendly extraction technology of natural plant oils has always received high attention from the industry. High-temperature steam extraction is currently a widely used physical extraction technology. Its core principle is to place the pre-treated plant material in a sealed extraction tank and introduce high-temperature saturated steam. The high-temperature steam provides heat to vaporize or reduce the viscosity of the oil components in the plant tissue, and also acts as a carrier to carry the vaporized or atomized plant oil out of the extraction tank. Subsequently, it is recovered through a condensation system to obtain crude plant oil.
[0003] Although this technology has advantages such as not using organic solvents and relatively simple operation, existing high-temperature steam extraction tank equipment and processes still have significant limitations in actual large-scale production applications, restricting further improvements in efficiency and economic benefits. Existing technologies generally fill the extraction tank with the plant raw materials to be extracted (such as broken seeds, peels, petals, etc.) in a static stacking manner. This stacking state results in high density and low porosity within the raw material layer.
[0004] When high-temperature steam is introduced from the bottom of the tank or a specific inlet, the steam tends to flow along the path of least resistance, such as the edge of the tank wall or localized loose channels in the feed layer, forming a "channeling" phenomenon. In the central area of a tightly packed feed layer, steam has difficulty penetrating effectively and distributing evenly, resulting in insufficient heating of the feed in that area and low efficiency in oil vaporization and diffusion. Meanwhile, after the extraction process is complete, a large amount of plant waste (residue) treated by the high-temperature steam remains in the tank. Cleaning this waste is also very inconvenient. Utility Model Content
[0005] This application provides a high-temperature extraction tank for extracting natural plant oils. By laying the material into layers of independent structures, the material can fully contact the high-temperature steam, effectively improving the extraction efficiency of plant oils and effectively solving the problems in the background technology.
[0006] To achieve the above objectives, this application provides the following technical solution: a high-temperature extraction tank for extracting natural plant oil, comprising a high-temperature chamber; a gas collecting hood is installed on the upper surface of the high-temperature chamber, a pressure sensor and an outlet pipe are installed on the upper surface of the gas collecting hood, and an air supply pipe is installed on the lower surface of the high-temperature chamber, the air supply pipe being connected to the outlet of an external steam generator for sending high-temperature steam into the interior of the high-temperature chamber, and the outlet pipe being connected to an external condenser.
[0007] The high-temperature chamber is connected to a base via support legs on its lower surface. The upper surface of the base is provided with a guide rail, and a baffle that can be automatically opened and closed is provided on the guide rail. Multiple trays are evenly distributed from top to bottom on the right side of the baffle. The upper surface of the tray is provided with a tray groove, and the interior of the tray groove is evenly distributed with a ventilation hole.
[0008] The inner side of the high-temperature chamber is evenly distributed with multiple hollow rectangular plates from top to bottom. The upper surface of the hollow rectangular plates is smooth, and multiple air vents are evenly distributed on the upper surface of the hollow rectangular plates. The number of trays is the same as the number of hollow rectangular plates.
[0009] The high-temperature chamber has a U-shaped interlayer inside, which is connected to the air supply pipe. Multiple strip partitions are arranged inside the U-shaped interlayer, which divides the interior of the U-shaped interlayer into multiple independent air channels. Each hollow rectangular plate has an independent air channel connected to it.
[0010] Preferably, a slider is slidably connected to the guide rail, and at least one vertical rod is installed on the upper surface of the slider. Multiple horizontal plates three are arranged from top to bottom on the outer side of the vertical rod. Multiple horizontal plates two are fixedly connected to the outer side of the baffle. The horizontal plates two are sleeved on the outer side of the vertical rod and can move up and down along the axial direction of the vertical rod. The horizontal plates two and three are arranged in a one-to-one correspondence, and the horizontal plates two are arranged above the horizontal plates three.
[0011] Preferably, a horizontal plate is installed at the lower end of the outer side of the vertical rod, and a stud with a head is threadedly connected to the outer side of the horizontal plate to adjust the lifting and lowering of the baffle.
[0012] Preferably, when the tray is placed on the upper surface of the hollow rectangular plate, the first vent hole and the second vent hole are connected.
[0013] Preferably, the base is equipped with a hydraulic telescopic rod for controlling the opening and closing of the baffle. The fixed end of the hydraulic telescopic rod is mounted on the base via a support, and the telescopic end of the hydraulic telescopic rod is connected to the slider.
[0014] Preferably, the left side of the high-temperature chamber is open, and an annular sealing ring is provided at the edge of the open.
[0015] Compared with the prior art, the beneficial effects of this application are:
[0016] 1. This application uses the design of evenly distributed pallets on the baffle and multi-layer hollow rectangular plates in the high-temperature chamber to separate the raw materials into independent thin layers and lay them in the pallet groove. After the steam is introduced into the U-shaped interlayer through the gas supply pipe, it is directionally transported to each hollow rectangular plate through multiple independent air channels divided by the strip partition, and finally penetrates the corresponding material layer vertically through the two vent holes.
[0017] 2. The hydraulic telescopic rod drives the slider to move along the guide rail, which drives the baffle and all the pallets to move out of the open left side of the high temperature box as a whole. When the pallets separate from the hollow rectangular plate, the caking waste is carried away from the tank along with the pallet groove, which facilitates the cleaning of waste.
[0018] 3. Independent air is connected to each hollow rectangular plate. Combined with the docking design of the first ventilation hole of the support plate and the second ventilation hole of the rectangular plate, the steam flow can be precisely controlled in layers as needed. For raw materials with different moisture content or particle size, the steam parameters of specific material layers can be adjusted to avoid component damage caused by local overheating.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Figure 2The orientations or positional relationships shown are for the convenience of describing this application and simplifying the description only, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] Please see Figure 1-4 This application provides the following technical solution: a high-temperature extraction tank for extracting natural plant oil, including a high-temperature chamber 8; a gas collecting hood 6 is installed on the upper surface of the high-temperature chamber 8, a pressure sensor 5 and a gas outlet pipe 7 are installed on the upper surface of the gas collecting hood 6, a gas supply pipe 9 is installed on the lower surface of the high-temperature chamber 8, the gas supply pipe 9 is connected to the gas outlet of an external steam generator, and is used to send high-temperature steam into the interior of the high-temperature chamber 8, and the gas outlet pipe 7 is connected to an external condenser.
[0027] Specifically, pressure sensor 5 monitors the steam pressure inside the tank in real time to avoid the risk of overpressure; the flared design of the gas collection hood 6 can efficiently collect vaporized grease, prevent condensation backflow, and form a closed "steam injection-oil and gas discharge-condensation recovery" cycle system.
[0028] The high-temperature chamber 8 is connected to a base 11 via a support leg 10 on its lower surface. The upper surface of the base 11 is provided with a guide rail 13, and a baffle 2 that can be automatically opened and closed is provided on the guide rail 13. Multiple trays 3 are evenly distributed from top to bottom on the right side of the baffle 2. The upper surface of the tray 3 is provided with a tray groove, and the interior of the tray groove is evenly distributed with a ventilation hole.
[0029] Specifically, the guide rail 13 is used to support the baffle 2, so that the baffle 2 can be opened and closed. The tray groove is used to support the layered raw materials to avoid accumulation. This design allows the raw materials to be dispersed in a thin layer, which significantly increases the steam contact area.
[0030] The inner side of the high-temperature chamber 8 is evenly distributed with multiple hollow rectangular plates 4 from top to bottom. The upper surface of the hollow rectangular plates 4 is smooth, and multiple air vents are evenly distributed on the upper surface of the hollow rectangular plates 4. The number of trays 3 is the same as the number of hollow rectangular plates 4.
[0031] Specifically, the pallet 3 is used in conjunction with the hollow rectangular plate 4. After the high-temperature steam is discharged through the hollow rectangular plate 4, it can directly contact the material on the upper surface of the pallet 3.
[0032] The high-temperature chamber 8 has a U-shaped interlayer inside, which is connected to the air supply pipe 9. Multiple strip partitions 21 are arranged inside the U-shaped interlayer, which divides the interior of the U-shaped interlayer into multiple independent air channels 20. Each hollow rectangular plate 4 has an independent air channel 20 connected to it.
[0033] Specifically, this configuration allows for the diversion of high-temperature steam, enabling it to enter different hollow rectangular plates 4 and thus ensuring that the material is heated evenly.
[0034] Furthermore, a slider 14 is slidably connected to the guide rail 13. At least one vertical rod 1 is installed on the upper surface of the slider 14. Multiple horizontal plates 17 are arranged from top to bottom on the outer side of the vertical rod 1. Multiple horizontal plates 16 are fixedly connected to the outer side of the baffle 2. The horizontal plates 16 are sleeved on the outer side of the vertical rod 1 and can move up and down along the axial direction of the vertical rod 1. The horizontal plates 16 and the horizontal plates 17 are arranged in a one-to-one correspondence. The horizontal plates 16 are arranged above the horizontal plates 17.
[0035] Specifically, the horizontal plate 3 17 is welded to the outer side of the vertical rod 1 to support the horizontal plate 2 16, which can move up and down along the vertical rod 1.
[0036] Furthermore, a horizontal plate 15 is installed at the lower end of the outer side of the vertical rod 1, and a headed stud 18 for adjusting the lifting and lowering of the baffle 2 is threadedly connected to the outer side of the horizontal plate 15.
[0037] Specifically, the baffle 2 can be adjusted by rotating the head stud 18. When feeding, the baffle 2 is first lifted by the head stud 18 so that the support plate 3 is slightly higher than the hollow rectangular plate 4, preventing the support plate 3 and the hollow rectangular plate 4 from interfering with each other.
[0038] Furthermore, when the tray 3 is placed on the upper surface of the hollow rectangular plate 4, the first vent hole and the second vent hole are connected.
[0039] Furthermore, a hydraulic telescopic rod 12 for controlling the opening and closing of the baffle 2 is installed on the base 11. The fixed end of the hydraulic telescopic rod 12 is installed on the base 11 through a support, and the telescopic end of the hydraulic telescopic rod 12 is connected to the slider 14.
[0040] Specifically, the extension and retraction of the hydraulic telescopic rod 12 is controlled by an external hydraulic station, and the outer surface of the hydraulic telescopic rod 12 is covered with an insulation layer.
[0041] Furthermore, the left side of the high-temperature chamber 8 is open, and an annular sealing ring 19 is provided at the edge of the open.
[0042] When using: When loading, first rotate the stud 18 forward. The end of the stud 18 will slightly lift the baffle 2 upward. Then, spread the soaked raw materials evenly in the tray groove on the upper surface of the tray 3.
[0043] The hydraulic telescopic rod 12 retracts to send the baffle 2 into the interior of the high-temperature chamber 8. When the baffle 2 is above the hollow rectangular plate 4, the head stud 18 is rotated in the opposite direction, and the pallet 3 falls on the upper surface of the hollow rectangular plate 4 under the action of gravity. Since the upper surface of the hollow rectangular plate 4 and the lower surface of the pallet 3 are both smooth, most of the high-temperature steam can be directly introduced into the pallet groove on the upper surface of the pallet 3 through the vent holes one and two.
[0044] Finally, the hydraulic telescopic rod 12 presses the baffle 2 tightly onto the annular sealing ring 19.
[0045] The steam generator is started, and high-temperature steam is sent into the independent air passage 20 through the air supply pipe 9, and then into the interior of the hollow rectangular plate 4 through the independent air passage 20. Finally, the steam fills the entire high-temperature chamber 8 through the vent hole. The extract is discharged with the high-temperature steam through the air outlet pipe 7 and enters the condenser for liquefaction and recovery.
[0046] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
