Part of the steam condenses into liquid, and the remaining steam enters the second-stage condenser and is further condensed through the spiral tube. Finally, it condenses into a mixture of essential oil and water. The mixture enters the oil-water separation bottle and is naturally stratified due to the density difference. The upper layer is essential oil and the lower layer is pure dew. The essential oil enters the essential oil drying bottle and flows into the essential oil collection bottle after being dehydrated by the desiccant. The pure dew flows into the pure dew collector through the control valve.

[0012] The oregano material is fixed by a bendable pressure plate to ensure that it is always immersed in water during the distillation process, which increases the contact area between the steam and the material and improves the efficiency of essential oil precipitation. The multi-stage condensation system can effectively condense the steam, reduce the loss of essential oil, and improve the purity of essential oil. In addition, when the water level in the distiller is too high, the liquid level gauge controls the solenoid valve to open, allowing excess water to flow back into the distiller through the overflow pipe to prevent it from entering the condenser and affecting the quality of the essential oil.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1: This example 1 provides a two-stage condensation oregano essential oil extraction device, which is directly improved on the existing essential oil extraction device and has a unique structure.

A distiller 1 is placed on the heater 2, and the control panel 5 is connected to the heater 2 for control. The control panel 5 is provided with a temperature regulating device, which can regulate the heater 2 through the signal feedback from the temperature sensor 12 to keep the temperature in the distiller 1 within a certain range. A waste pipe 14, a water level observation port 16 and an L-shaped reflux pipe 17 are provided at the lower part of the distiller 1, and an overflow pipe 19 is provided at the upper part of the distiller 1, and both the waste pipe 14 and the overflow pipe 19 are provided with a first valve 15; the reflux A feed hopper 18 is fixedly installed on the upper end of the tube 17, and the output end of the overflow pipe 19 is located directly above the feed hopper 18; a sealing cover 20 is detachably installed on the top of the distiller 1, and there are various ways to install the sealing cover 20, for example: threaded connection or snap-fitting onto the distiller 1, a temperature sensor 12 is provided on the sealing cover 20, and a plurality of limit plates 22 are evenly fixedly installed along the circumference on the inner wall of the distiller 1, and a bendable pressure plate 21 is provided in the distiller 1 below the limit plate 22, and a plurality of circular holes are evenly opened on the pressure plate 21, and the pressure plate 21 is made of elastic material to prevent the material from floating on the water surface during the distillation process, resulting in the inability to fully precipitate the essential oil.

[0023] The first-stage condenser is arranged obliquely between the distiller 1 and the second-stage condenser, and the upper and lower ends of the first-stage condenser are respectively connected to the top of the distiller 1 and the second-stage condenser, and the oil-water separation bottle 9 is arranged below the output end of the second-stage condenser; the first-stage condenser includes a water-cooling tube 11 and a condenser 24, both ends of the interior of the condenser 24 are fixedly sleeved with connecting rings, and the two connecting rings are fixedly sleeved on the outside of the water-cooling tube 11, the bottom of the lower end of the condenser 24 is provided with a water inlet 25, and the top of the upper end of the condenser 24 is provided with a water outlet 26; the sealing cover 20 and the top of the second-stage condenser are fixedly installed with threaded connectors, and the distiller 1 and the second-stage condenser are both connected by screws. The threaded connector is connected to the water-cooling pipe 11; the stage II condenser includes a stage II condenser shell 27, in which an upper sealing plate 32 and a lower sealing plate 34 are fixedly installed at vertical intervals. The two sealing plates divide the stage II condenser shell 27 into three chambers: upper, middle and lower. A plurality of spiral tubes 33 are evenly distributed along the circumference of the middle chamber, and the two ends of the spiral tubes 33 are respectively connected to the upper and lower chambers. The water-cooling pipe 11 is connected to the upper chamber, and the upper and lower ends of the middle chamber are respectively provided with a water inlet pipe 30 and a water outlet pipe 31. An oil-water discharge pipe 29 is fixedly installed at the bottom of the lower chamber, and the other end of the oil-water discharge pipe 29 extends into the oil-water separation bottle 9.

[0024] There are various condensation methods for the first-stage condenser and the second-stage condenser. For example, the water inlet 25 and the water inlet pipe 30 are both connected to the input end of the chiller, and the water outlet 26 and the water outlet pipe 31 are both connected to the input end of the chiller. The chiller delivers cold water to the condenser pipe 24 and the middle chamber, respectively, to condense the high-temperature steam. An oil-water separation level monitor 35 is provided on one side of the oil-water separation bottle 9. The oil-water separation bottle 9 has an essential oil discharge pipe 10 at the top and a pure oil exposure pipe 13 at the bottom. The pure oil exposure pipe 13 is provided with a second valve 28, and the second valve 28 is controllably connected to the oil-water separation level monitor 35. The oil-water separation line monitor 35 uses image recognition to identify the oil-water separation line after stratification, thereby controlling the opening and closing size of the second valve 28, so that the oil-water separation line after stratification is controlled within a certain range; one end of the essential oil discharge pipe 10 extends into the essential oil drying bottle 8, and the essential oil drying bottle 8 is filled with a desiccant. There are many options for desiccant, such as sodium sulfate, which is used to further absorb a small amount of water in the essential oil. An essential oil discharge pipe 23 is provided at the bottom of the essential oil drying bottle 8, and the pure dew collector 6 is located directly below the output end of the pure dew pipe 13, and the essential oil collection bottle 7 is located directly below the output end of the essential oil discharge pipe 23.

[0025] When we use the essential oil extraction device to extract oregano essential oil, first, both the first-stage condenser and the second-stage condenser are connected to the chiller to circulate cold water in the two condensers, and then the sealing cover 20 in the distiller 1 is opened, the pressing plate 21 is bent and taken out, and then the crushed oregano is placed in the distiller 1, and the pressing plate 21 is bent again and placed under the limit plate 22, and then distilled water is poured in so that the height of the distilled water is above the limit plate 22, so that the oregano is always immersed in the distilled water; the heater 2 is started to heat the distiller 1. After heating, the oil-water mixed steam is condensed by two condensers and then drips into the oil-water separation bottle 9, and is stratified in the oil-water separation bottle 9. The oregano essential oil in the upper layer drips into the essential oil drying bottle 8, and is dehydrated by the desiccant in the essential oil drying bottle 8 and flows into the essential oil collecting bottle 7. The oil-water separation line monitor 35 identifies the oil-water separation line after stratification through the image recognition system. When the oil-water separation line reaches the preset position, the oil-water separation line monitor 35 controls the opening of the second valve 28 to allow the pure dew in the lower layer of the oil-water separation bottle 9 to flow into the pure dew collector 6.

[0026] Example 2: The difference between Example 2 and Example 1 is that Figure 1 As shown, a plurality of universal wheels 4 are fixedly mounted on the bottom of the frame 3, and the plurality of universal wheels 4 are symmetrically distributed in a rectangular shape. A liquid level gauge is provided in the distiller 1. There are various options for the liquid level gauge, for example: a two-color water level gauge. The valve on the overflow pipe 19 is a solenoid valve. The liquid level gauge is controlled and connected to the solenoid valve. When the water in the distiller 1 boils, causing the water level to rise to the sealing cover 20, the liquid level gauge controls the solenoid valve to open, and the water flow at the top of the distiller 1 flows from the overflow pipe 19 to the feed hopper 18. After cooling in the feed hopper 18, it flows back to the distiller 1 through the reflux pipe 17, thereby preventing the water flow from entering the first-stage condenser when boiling, thereby affecting the extraction of essential oils.
