Description

Technical Field

[0001] This invention relates to a flexible pretreatment device and method for oil using infrared and plasma coupling, belonging to the field of raw material pretreatment technology. Background Technology

[0002] Oilseed pretreatment is a crucial preliminary step in oil extraction, directly determining oil yield, oil quality, and subsequent refining costs. It is core to ensuring oil production efficiency and product competitiveness. In traditional oil production, oilseed pretreatment often employs hot air drying and steaming techniques. While these methods are mature, they suffer from drawbacks such as high energy consumption, low efficiency, and the potential for chemical residues or negative impacts on oil flavor, making it difficult to meet the demands of modern oil production for high efficiency, environmental friendliness, and high quality.

[0003] Plasma technology generates plasma rich in high-energy electrons and active particles (such as ozone, atomic oxygen, and free radicals) through electrical discharge. This plasma can etch the cell walls and cell membranes of oilseeds, disrupt the hydrophobic waxy layer and phospholipid structure, and increase cell permeability, creating conditions for oil release. Infrared radiation technology (especially mid- and far-infrared radiation) can be directly absorbed by water, protein, and oil molecules within the oilseeds. Through "inside-out" heating, it rapidly vaporizes the water inside the seed, generating pressure that bursts the cell structure, facilitating oil release. Simultaneously, it can improve oil flavor and increase oil yield.

[0004] However, plasma technology is sensitive to the moisture content of oilseeds. Excessive humidity creates a water film that hinders the process, while insufficient humidity shortens the lifespan of active particles, making it difficult to achieve synergistic effects of moisture regulation and cell wall disruption. Infrared radiation technology has high energy consumption, making it difficult to control costs in industrial production and limiting its large-scale application.

[0005] Therefore, there is an urgent need for an oilseed pretreatment device that can reduce the energy consumption of traditional seed roasting and improve the processing effect. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a flexible oilseed pretreatment device and method using infrared and plasma coupling, which can reduce energy consumption, increase oil yield, and achieve efficient oilseed processing.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides a flexible oil pretreatment device coupled with infrared and plasma, comprising: The outer casing is a box structure; A plasma generator is installed at one end of the housing; An infrared radiation plate is installed at one end of the housing and is located on the same side as the plasma generator; A material tray is located on one side of the plasma generator and the infrared radiation plate; A lifting platform is connected to the material pallet and drives the material pallet to move within the outer casing; A thermal imaging device is mounted on the infrared radiation plate and connected to the control system.

[0013] In one embodiment of the invention, a knob and a connector are included, the plasma generator being connected to the housing via the connector, and the knob being connected to the screw.

[0014] Secondly, the present invention also provides an infrared-plasma coupled oil flexible pretreatment method, including the aforementioned infrared-plasma coupled oil flexible pretreatment equipment, the method comprising: S1: Place the oilseeds to be pressed on the material tray, and rotate the knob to drive the drive structure to rotate, thereby causing the scissor arm assembly to retract or expand, so that the material tray rises or falls, and adjusts the material tray to a position 3~5cm away from the infrared radiation plate and plasma generator; S2: Turn on the power to power on the infrared radiation plate and the plasma generator. Heating is performed through the infrared radiation plate for 10 minutes, and the plasma generator is used for 1 minute. S3: The thermal imaging device captures an image of the surface temperature distribution of the oil on the material tray and transmits it to the control system. The temperature inside the box is observed through the first display screen and adjusted by the button to reach the preset temperature for processing the oil. S4: After pretreatment is completed, the material tray is returned to its initial position by reversing the knob, and the pretreated oil is transported to a single screw press to produce seed oil under certain temperature conditions, and the oil yield is determined.

[0015] In one embodiment of the present invention, the temperature of the infrared radiation plate is controlled within the range of 100~150°C.

[0016] In one embodiment of the present invention, the oil yield of the oilseed is determined according to the Soxhlet extraction method: oil yield = (mass of extracted oil / oil content of the material) * 100%.

[0017] The beneficial effects of this invention are: The present invention provides a flexible oil pretreatment device and method coupled with infrared and plasma, which has the following advantages: 1.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 3As shown, this invention provides a flexible oilseed pretreatment device using infrared and plasma coupling. This device can reduce energy consumption, increase oil yield, and achieve efficient oilseed processing. The device has a box-type structure, including a plasma generator 1, an infrared radiation plate 2, a shell 17, and a material tray 3. The plasma generator 1 and infrared radiation plate 2 are mounted on the shell 17, and the material tray 3 is installed inside the shell 17, below the plasma generator 1 and infrared radiation plate 2. The plasma generator 1 and infrared radiation plate 2 can pretreat the oilseeds on the material tray 3. The oilseeds can be first baked by the infrared radiation plate 2 and then processed by the plasma generator 1, or both can be activated simultaneously for synergistic flexible pretreatment.

[0028] In some embodiments, the plasma generator 1 is of the dielectric barrier discharge type, and there are four of them, which are fixed to the top of the device housing 17 by the connector 6. The four plasma generators 1 are parallel to each other and spaced a certain distance apart. After being powered on, the plasma generator 1 can break down the air and generate plasma containing high-energy electrons and active particles. The plasma diffuses to the surface of the oil, which can etch the cellular structure of the oil surface and play a certain role in sterilization.

[0029] In some embodiments, several infrared radiation plates 2 are provided, located in the central area of ​​the four plasma generators 1. The infrared radiation plates 2 can be fixed to the housing 17 by welding or by mounting them to the housing 17 via connectors 6. After being powered on, the infrared radiation plates 2 can radiate mid- and far-infrared rays downwards, rapidly heating the oil from the inside out, thereby destroying its internal cellular structure. The pretreatment equipment is equipped with a thermal imaging device 16, which is connected to the infrared radiation plates 2 and can be an integrated structure. The entire device is composed of a high-temperature resistant industrial-grade imaging module, and an optical lens is provided inside. The optical lens is vertically oriented towards the material tray 3 to collect images of the surface temperature distribution of the oil in the material tray 3 during the heating process by the infrared radiation plates 2 and the plasma generators 1 in real time.

[0030] In some embodiments, the material pallet 3 is mounted on a scissor lift platform 5. The lift platform 5 includes a drive structure 51 and a scissor arm assembly 52. ​​The drive structure 51 is connected to the scissor arm assembly 52 and provides driving force to the scissor arm assembly 52. ​​The scissor arm assembly 52 is connected to the material pallet 3 and can move the material pallet 3 up and down within the housing 17. The scissor arm assembly 52 consists of multiple sets of X-shaped arms 521 hinged together by a central shaft 523. Each end of the X-shaped arm 521 has a hinge structure 522. The multiple sets of X-shaped arms 521 are connected by the hinge structure 522, and their upper ends are connected to the material pallet 3. Driven by the drive structure 51, the X-shaped arms 521 can rotate around the central shaft 523. The drive structure 51 is located below the scissor arm assembly 52 and connected to the hinge structure 522 of the scissor arm assembly 52. ​​It can drive the scissor arm assembly 52 to retract or expand, thereby moving the material pallet 3 up or down. The scissor arm assembly 52 can be equipped with multiple X-shaped arms 521, the number of which can be set according to the lifting distance of the material pallet 3.

[0031] In some embodiments, the drive structure 51 is a screw structure, including a screw 511 and a nut slider 512. Two nut sliders 512 are sleeved on the outer periphery of the screw 511 and are threadedly connected to the screw 511. The scissor arm assembly 52 is connected to the nut slider 512 via a hinge structure 522 on the X-shaped arm 521. A knob 4 is provided at the end of the screw 511 opposite to the nut slider 512. The knob 4 is fixedly connected to the screw 511, which passes through the housing 17 and is rotatably connected to it. Rotating the knob 4 drives the screw 511 to rotate, causing the X-shaped arm 521 to rotate around the central axis 523 and retract inward, thereby raising the material tray 3. When lowering is required, simply rotate the knob 4 in the opposite direction to move the nut slider 512 along the screw 511 to both ends, thereby lowering the material tray 3. The lifting platform 5 moves the material tray 3 up and down, thereby achieving precise and stable adjustment of the height of the material tray 3. This facilitates flexible control of the position of the material tray 3, making it suitable for oils of different volumes and preventing the oil from contacting the upper components.

[0032] In some embodiments, the housing 17 is equipped with a control switch 7 and an instrument panel 8. The plasma generator 1 and the infrared radiation plate 2 are connected to the control switch 7, and the plasma generator 1 and the infrared radiation plate 2 are connected to an external power supply for power. The control switch 7 controls the opening and closing of the external power supply to power the equipment. The thermal imaging device 16 is connected to the control system of the instrument panel 8. The thermal imaging device 16 transmits the collected oil surface temperature distribution image to the control system. The operator can observe the thermal image on an external computer and adjust the parameters based on the temperature distribution displayed in the thermal image to achieve intelligent control based on the uniformity of the temperature field.

[0033] In some embodiments, a detection unit 15 is also installed inside the housing 17. The detection unit 15 is a temperature sensor used to detect the temperature inside the housing in real time and provide real-time feedback to the control system.

[0034] In some embodiments, the instrument panel 8 is provided with several displays, adjustment buttons, and a switching button 12. The switching button 12 is a function switching button used to switch between setting infrared temperature and infrared time. The adjustment buttons include a first adjustment button 13 and a second adjustment button 14, which can respectively adjust the set value upwards or downwards, with an adjustment step of 1. Specifically, the first adjustment button 13 is used to increase the infrared temperature or infrared time in steps of 1, and the second adjustment button 14 is used to decrease the infrared temperature or infrared time in steps of 1. The instrument panel 8 is provided with multiple displays, including a first display 9, a second display 10, and a third display 11. Display 9 is connected to the detection unit 15 and can display the internal temperature of the pretreatment equipment. The second display 10 is used to display the set infrared temperature, and the third display 11 is used to display the remaining infrared baking time. When the internal temperature of the equipment deviates from the set temperature by more than 5°C, the equipment will automatically adjust the infrared temperature to bring the internal temperature of the equipment closer to the set value.

[0035] In some embodiments, the outer shell 17 is made of metal, and the outer side of the outer shell 17 may be covered with a layer of heat insulation material to achieve good heat insulation effect and avoid excessive heat exchange with the outside during infrared baking.

[0036] Alternatively, connector 6 can be made of bolts, which provides a secure connection and facilitates disassembly, thus aiding in later maintenance and installation.

[0037] Furthermore, this invention also provides an infrared-plasma coupled oil flexible pretreatment method, which uses the aforementioned infrared-plasma coupled oil flexible pretreatment equipment. The specific method is as follows: S1: Place the oilseeds to be pressed on the material tray 3. Rotate the knob 4 to drive the screw 511 to rotate. The rotation of the screw 511 drives the nut slider 512 to slide, thereby driving the scissor arm assembly 52 to retract or expand, so that the material tray 3 rises or falls, and adjusts the material tray 3 to a position of 3~5cm away from the infrared radiation plate 2 and the plasma generator 3. S2: Turn on the control switch 7 to power on the infrared radiation plate 2 and the plasma generator 1. The temperature of the infrared radiation plate 2 is controlled within the range of 100~150℃, and the processing time is 10min. The processing time of the plasma generator 1 is 1min. S3: The thermal imaging device 16 captures an image of the surface temperature distribution of the oil on the material tray 3 and transmits it to the control system. The temperature inside the box is observed through the first display screen 9 and adjusted by the switching button 12 to reach the preset temperature for processing the oil. S4: After pretreatment, reverse knob 4 to return material tray 3 to its initial position, and transport the pretreated oil to a single screw press to extract seed oil under certain temperature conditions; according to Soxhlet extraction method: oil yield = (mass of extracted oil / oil content of material) * 100%, determine the oil yield of the oil.

[0038] Example 1 This embodiment uses the above-mentioned infrared and plasma coupled flexible oil pretreatment equipment and method. The material is peanut kernels, and the steps for extracting peanut oil are as follows: Place the peanuts to be pressed on the material tray 3. Rotate the knob 4 to drive the screw 511 to rotate. The rotation of the screw 511 causes the nut slider 512 to slide, thereby causing the scissor arm assembly 52 to retract, making the material tray 3 rise and adjusting the material tray 3 to a position 4cm away from the infrared radiation plate 2 and the plasma generator. Turn on the control switch 7 to power on the infrared radiation plate 2 and the plasma generator 1. The temperature of the infrared radiation plate 2 is controlled at 140°C and the processing time is 10 min. The processing time of the plasma generator 1 is 1 min. The thermal imaging device 16 captures an image of the surface temperature distribution of peanuts on the material tray 3 and transmits it to the control system. The temperature inside the box is observed through the first display screen 9 and adjusted by the switching button 12 to reach the preset temperature for processing the peanuts. After pretreatment, the material tray 3 is returned to its initial position by reversing knob 4, and the pretreated peanut kernels are transported to a single screw press to extract peanut oil under certain temperature conditions. According to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanuts) * 100%, the oil yield of peanut kernels is determined to be 84.27 ± 0.77%.

All other conditions are the same as in embodiment 1. Finally, according to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanut) * 100%, the oil yield of peanut kernels is determined to be 88.23 ± 1.05%.

[0042] Example 5 This embodiment uses the above-mentioned infrared and plasma coupled flexible oil pretreatment equipment and method. The material is peanut kernels. The difference between the preparation method in this embodiment and that in embodiment 1 is that the processing time of plasma generator 1 is adjusted to 5 minutes. All other conditions are the same as in embodiment 1. Finally, according to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanut) * 100%, the oil yield of peanut kernels is determined to be 92.79 ± 0.11%.

[0043] Example 6 This embodiment uses the above-mentioned infrared and plasma coupled flexible oil pretreatment equipment and method. The material is peanut kernels. The difference between the preparation method in this embodiment and that in embodiment 1 is that the processing temperature of the infrared radiation plate 2 is adjusted to 145℃. All other conditions are the same as in embodiment 1. Finally, according to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanut) * 100%, the oil yield of peanut kernels is determined to be 84.50 ± 0.66%.

[0044] Comparative Example 1 In this comparative example, the peanut kernels were not pretreated using the device provided by the present invention. All other conditions were the same as in Example 1. The peanut kernels were directly put into a single screw press for oil extraction. According to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanut) * 100%, the oil yield of the peanut kernels was determined to be 73.22 ± 0.33%.

[0045] Comparative Example 2 In this comparative example, the device provided by the present invention is used to pre-treat peanut kernels. However, the difference between this comparative example and Example 1 is that the plasma generator 1 is turned off, and all other conditions are the same as in Example 1. The peanut kernels are put into a single screw press for oil extraction. According to the Soxhlet extraction method: oil yield = (mass of extracted peanut oil / oil content of peanuts) * 100%, the oil yield of the peanut kernels is determined to be 80.95 ± 0.64%.

[0046] Comparative Example 3 In this comparative example, the device provided by the present invention was used to pretreat peanut kernels.

[0047] Table 1 Oil yield analysis results

[0048] In summary, as shown in Table 1, the oil yield of peanut oil in Comparative Example 1 without any pretreatment was 73.22 ± 0.33%, while the oil yield of peanut oil in Comparative Example 2, pretreated with infrared radiation plate 2, was 80.95 ± 0.64%, representing an increase of 7.33% compared to Comparative Example 1. Appropriately extending the treatment time of infrared radiation plate 2 and appropriately increasing the infrared treatment temperature did not significantly improve the oil yield. However, as shown in Examples 1 to 5, the oil yield significantly increased after pretreatment with the coupled plasma generator 1, and this increase gradually increased with the extension of the pretreatment time of plasma generator 1. Therefore, pretreatment of raw materials with infrared radiation plate 2 coupled with plasma generator 1 can significantly improve the oil yield of the raw materials. Simultaneously, the pretreatment with plasma generator 1 can synergistically damage peanut cells with the pretreatment with infrared radiation plate 2, reducing the treatment time of infrared radiation plate 2, thereby reducing the overall energy consumption of the equipment and improving processing efficiency.
