[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 3 As shown in the embodiment of this utility model, a plant essential oil extraction device includes a support 1; a glass still 2 is fixedly connected to the middle of the support 1; a sealing cap 3 is installed on the top of the glass still 2 via a flange; an ultrasonic atomizer 4 is fixedly connected to the top of the support 1; a water pipe 5 is fixedly connected to the output end of the ultrasonic atomizer 4; the water pipe 5 is a wear-resistant flexible hose; the water pipe 5 penetrates the side wall of the sealing cap 3 and is fixedly connected to an annular pipe 6; the water pipe 5 and the sealing cap 3 are fixedly connected to each other; multiple fixing rods 7 are fixedly connected between the annular pipe 6 and the sealing cap 3; multiple atomizing nozzles 8 are fixedly connected to the middle of the annular pipe 6; a placement structure is installed inside the glass still 2; the placement structure is used to place raw materials; and a filling device is installed inside the glass still 2. Heat pipe 21; The glass still 2 has a distillation outlet on its side wall. During operation, rose petals are placed inside the glass still 2, and an appropriate amount of purified water is added. The glass still 2 is then sealed with a sealing cap 3 and a flange. First, the ultrasonic atomizer 4 is turned on, and the atomizing nozzle 8 sprays deionized water to wet the petal rotor for 10 minutes. Then, the heating pipe 21 is turned on to start distillation. The distilled steam enters the condenser through the distillation outlet for further condensation. By using the method of atomizing and wetting the rose petals before distillation, the retention rate of key aroma components such as linalool and citronellol can be improved during the extraction of rose petal essential oil, thus increasing the quality of the extracted essential oil.
[0025] like Figures 1 to 2As shown, a vacuum pump 22 is fixedly connected to the top of the support 1; an air duct 23 is fixedly connected to the output end of the vacuum pump 22; the air duct 23 passes through the side wall of the glass still 2 and is fixedly connected to the glass still 2; a pressure gauge 24 is installed on the vacuum pump 22. During operation, the air pressure inside the glass still 2 is controlled by the vacuum pump 22, so that the rose petals inside the glass still 2 are kept at 60°C and maintained at a slight negative pressure of -0.05MPa during the distillation process. By keeping the raw material at a low temperature during the extraction of rose petal essential oil, the heat-sensitive components in the raw material are protected while improving the purity of the aroma.
[0026] like Figures 2 to 5 As shown, the placement structure includes a drive motor 9; the drive motor 9 is fixedly connected to the bracket 1; a rotating rod 10 is rotatably connected to the middle of the glass still 2; a shaft seal is installed between the rotating rod 10 and the glass still 2; a first synchronous pulley 11 is fixedly connected to the output end of the drive motor 9; a second synchronous pulley 12 is fixedly connected to the end of the rotating rod 10; a synchronous belt 13 is installed between the first synchronous pulley 11 and the second synchronous pulley 12; multiple fixed frames 14 are fixedly connected to the middle of the rotating rod 10; screen trays 15 are provided on the fixed frames 14; the multiple screen trays 15 are staggered. During operation, by spreading rose petals on the screen trays 15, during the distillation process, the drive motor 9 drives the first synchronous pulley 11 to rotate, and at the same time, under the connection of the synchronous belt 13 and the second synchronous pulley 12, the rotating rod 10 drives the multiple screen trays 15 to rotate at a low speed. By spreading the petals in layers, the steam penetrates from bottom to top, reducing the channel effect caused by accumulation. At the same time, the low-speed rotation can promote the release of substances inside the raw materials, increasing the effect of essential oil extraction.
[0027] like Figures 2 to 5 As shown, the side wall of the fixed frame 14 is fixedly connected to a slot 17; the side wall of the screen tray 15 is fixedly connected to a block 16; the block 16 and the slot 17 are engaged. During operation, by using the block 16 and the slot 17 to engage, the installation and removal of the screen tray 15 on the fixed frame 14 are made more convenient, and the waste residue is easier to clean after the rose petal essential oil is extracted from the inside of the screen tray 15.
[0028] like Figure 5 As shown, a rubber pad 18 is fixed to the inner wall of the slot 17. During operation, by installing the rubber pad 18 inside the slot 17, the stability of the screen tray 15 can be increased by the friction of the rubber pad 18 when the card block 16 is inserted into the slot 17.
[0029] like Figure 5As shown, a plurality of guide rods 19 are fixedly connected to the top of the screen tray 15; a screen pressure plate 20 is slidably connected to the middle of the guide rods 19. During operation, when the raw material is spread inside the screen tray 15, the screen pressure plate 20 presses against the surface of the raw material when it slides downward, which can reduce the problem of the raw material floating and overlapping when the screen tray 15 rotates, and improve the effect of essential oil extraction.
[0030] Working principle: Rose petals are placed inside glass still 2, and an appropriate amount of purified water is added. The still 2 is then sealed with a sealing cap 3 and a flange. First, the ultrasonic atomizer 4 is turned on, causing the atomizing nozzle 8 to spray deionized water onto the petal rotor for 10 minutes. Then, the heating tube 21 is turned on to begin distillation. The distilled steam enters the condenser tube through the distillation outlet for further condensation. By using the method of atomizing and wetting the rose petals before distillation, the retention rate of key aroma components such as linalool and citronellol can be improved during the extraction of rose petal essential oil, thus increasing the quality of the extracted essential oil.
[0031] By using vacuum pump 22 to control the air pressure inside glass still 2, the rose petals inside glass still 2 are kept at 60°C and maintained at a slight negative pressure of -0.05MPa during distillation. This low-temperature distillation of the raw material during the extraction of rose petal essential oil protects the heat-sensitive components in the raw material while improving the purity of the aroma.
[0032] By spreading rose petals on the screen tray 15, during the distillation process, the drive motor 9 drives the first synchronous wheel 11 to rotate. At the same time, under the connection of the synchronous belt 13 and the second synchronous wheel 12, the rotating rod 10 drives multiple screen trays 15 to rotate at a low speed. By spreading the petals in layers, the steam penetrates from bottom to top, reducing the channel effect caused by accumulation. At the same time, the low-speed rotation can promote the release of substances inside the raw material, increasing the effect of essential oil extraction.
[0033] By using the locking blocks 16 and the slots 17 for locking connection, the installation and removal of the screen tray 15 on the fixed frame 14 are made more convenient, and the waste residue is easier to clean after the rose petal essential oil inside the screen tray 15 is extracted.
[0034] By installing a rubber pad 18 inside the slot 17, the stability of the screen tray 15 can be increased by the friction of the rubber pad 18 when the card block 16 is inserted into the slot 17.
[0035] By spreading the raw materials inside the screen tray 15 and pressing the screen plate 20 against the surface of the raw materials when it slides downwards, the problem of the raw materials floating and overlapping when the screen tray 15 rotates can be reduced, thus improving the extraction effect of essential oils.
