Description

Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to a novel geranium essential oil extraction device. Background Art

[0002] Geranium essential oil is a commonly used natural aromatic substance with a comprehensive sweetness, a complex taste of rose and mint. Geranium essential oil is colorless or light green and is commonly used in the fields of beauty and medicine. Geranium essential oil is generally extracted by an extraction method. Specifically, the collected flowers and leaves of geranium trees are prepared by crushing, distilling, separating (collectively referred to as extraction) and other processes. In the prior art, especially in small-scale production areas, the relevant equipment used to extract geranium essential oil is generally in a split structure. During operation, the staff crushes the washed raw materials through a crushing device, and then sends the raw materials mixed with water into a distiller for distillation, condenses them into liquid through a condensing mechanism, and finally collects the distilled geranium essential oil through a collecting device, and separates the water to obtain the final geranium essential oil product.

[0003] Although the existing geranium essential oil extraction device meets the production needs to a certain extent, it is limited by the structure and still has the disadvantages of being not compact and occupying relatively more space in the production area. The corresponding cumbersome operation process brings inconvenience to the staff and is not conducive to improving work efficiency. In addition, the existing pulverizer equipped with the extraction device relies on water pressure flushing to transport water and crushed raw materials downward. In this way, due to the low pressure inside the pulverizer, when the powdered raw materials are blocked in the pulverizer discharge port for various reasons, it will have an adverse effect on the crushing and subsequent work. Finally, the distillation mechanism of the extraction device does not have an over-temperature detection function. After the internal liquid evaporates, if the power supply is not turned off in time, there is a probability that the temperature of the distillation equipment is too high, resulting in the probability of overheating and denaturation of the crushed geranium tree flowers and leaf raw materials (for example, the flowers and leaf raw materials are burnt and produce odors), and the odor generated enters the finished geranium essential oil, which has an adverse effect on the quality of the finished geranium essential oil. In summary, it is particularly necessary to provide a geranium essential oil extraction device that is compact in structure, easy to use, and can disconnect the power supply of the distillation mechanism when the amount of liquid inside the distillation mechanism decreases to a certain extent, so as to ensure the product quality as much as possible.

The overall structure has the advantages of compact structure, small installation space, and easy use. The raw materials can enter the distillation mechanism after being crushed by compressed air, which reduces the probability of blockage inside the crushing mechanism, and can monitor the temperature data in the distillation mechanism in real time. When the temperature is higher than the threshold, the power can be turned off in time and the staff can be prompted, thereby reducing the deterioration of the quality of the finished product caused by changes in the properties of the raw materials.

[0019] Figure 1 , 2As shown, the novel structure is based on a crushing mechanism, a distillation mechanism, a separation mechanism, a condensation mechanism, etc., and multiple mechanisms are integrated together. The overall structure has the advantages of compact structure, small installation space, and convenient use. After the AC 220V power supply enters the power input terminal 1 and 2 of the power module W, its 3 and 4 feet will output a stable DC 12V power supply control circuit and the power input terminal of the power switch SN and S1N. Before work, open the corresponding power switch SN of the solenoid valve DC5, the solenoid valve DC5 is powered on and the valve core is opened (and the power switch S1N is turned on, and the eight sets of semiconductor refrigeration sub-mechanisms MN are powered to generate cold to cool the water in the outer box 31, generally at a temperature of about -5 ° C), and tap water enters the outer box 31 (close the corresponding power switch SN after the water is full), and prepare for cooling the corresponding geranium essential oil gas (later, the corresponding power switch SN of the solenoid valve DC6 can be opened, and the solenoid valve DC6 is powered on and the valve core is opened, and the tap water is discharged from the outer box 31. After the water is discharged, the corresponding power switch SN is closed).

[0020] Figure 1 , 2As shown, the specific working process of the present invention is as follows. (1) The staff removes the nut of the sealing cover 102, opens the sealing cover 102, and puts an appropriate amount of flowers and leaves of geranium trees (hereinafter collectively referred to as raw materials) into the feeding bin 101 (because the content of aromatic substances varies before and after the flowers bloom, fresh fragrant leaves before flowering are generally selected as raw materials, and the fragrant geraniums are cut and picked and cleaned in advance to remove impurities and residual soil), and then closes the sealing cover 102 and fixes the sealing cover 102 by locking the nut to seal it. (2) Turn on the power switch S3 of the motor reducer M3 of the electric rotary valve sub-mechanism, so that the rotating shaft of the motor reducer M3 drives the rotating plate 1093 to rotate and continuously input the raw materials in the feed bin into the crushing bin 108 (including solvent water). At the same time, the staff turns on a power switch SN corresponding to the solenoid valve DC1, and the solenoid valve DC1 is electrically opened, so that the tap water and the raw materials enter the crushing bin 108 simultaneously (and turn on the power switch S1 of the vibration motor M1. The vibration motor is more conducive to the raw materials entering the crushing bin and entering the distillation box 1. Turn on the power switch S2 of the crushing mechanism M2, and the crushing knife inside the crushing mechanism crushes the raw materials into powder; crushing increases the contact surface area between the raw materials and the subsequent water vapor, which is conducive to the release of the extracted essential oil substances. Tap water is used as a solvent and is conducive to the raw materials entering the crushing bin 108 and the distillation tank 21 (the solvent precipitates the effective ingredients of geranium essential oil in the raw materials). (3) After about 5 minutes, turn off the crusher The power switch of the mechanism is turned on to complete the crushing work (generally, the power switch of the solenoid valve DC1 is turned off after 30 seconds of water inflow, and water is no longer inflowing into the feed bin). (4) Turn on the power switch SN corresponding to the solenoid valve DC3, and the valve core of the solenoid valve DC3 is turned on by electricity, and the power switch SN corresponding to the solenoid valves DC2 and DC4 is turned on by electricity, and the valve cores of the solenoid valves DC2 and DC4 are turned on by electricity, so that the high-compressed air output by the air compressor enters the feed bin and outputs the crushed raw materials into the distillation box together with the water (the solenoid valve DC4 discharges the air entering the distillation box); because the compressed air helps the crushed raw materials enter the distillation mechanism, the probability of blockage inside the crushing mechanism is reduced; after all the crushed raw materials enter the distillation box, turn off the power switches of the solenoid valves DC3, DC2, and DC4, and the valve cores of the solenoid valves DC3, DC2, and DC4 are turned off (and the motor reducer M3 and the power switches of the crushing mechanism and the vibration motor are turned off).(5) Entering the distillation process (in actual situations, the raw materials can be crushed multiple times so that the solid and liquid raw materials entering the distillation box reach a certain amount before distillation is carried out); after turning on the power switch ST, the control circuit is energized and starts working. When the temperature in the distillation box 21 is lower than 100°C, the internal contacts of the temperature switch W1 are closed, so that the relay J1 is energized to attract its control power input terminal and the normally open contact terminal to close. Then, the four sets of electric heating plates RT are energized to heat and distill the solid-liquid mixed raw materials in the distillation box 21. The water evaporates and takes away the boiling water. The effective essential oil components in the raw materials enter the cooling pipe 32 of the condensing mechanism; when the temperature in the distillation box 21 is higher than 100°C, the internal contact of the temperature switch W1 is open, so that the relay J1 will lose power and no longer attract its control power input terminal and the normally open contact terminal to open, and then the four sets of electric heating plates RT lose power and no longer heat the solid-liquid mixed raw materials in the distillation box 21. Through the above, it can be ensured that the temperature in the distillation box is 100°C, and it is ensured that the water evaporates after boiling and takes away the effective essential oil components in the raw materials into the cooling pipe 32 of the condensing mechanism. (6) After the pressure evaporates, the water and essential oil components flow into the upper end of the cooling pipe 32 and flow out from the lower end into the outer shell 61 (transparent plastic material). Under the action of the cooling water in the outer shell, the water and essential oil components will be effectively condensed into liquid and enter the outer shell 61 (the air in the outer shell is discharged to the atmosphere through the one-way air valve 63). (7) After all distillation is completed, turn off the power switch ST, the electric heating plate loses power, and the power switch of the semiconductor refrigeration mechanism MN is turned off simultaneously; in actual situations, when the distillation process is normal (when the temperature is lower than about 101°C), the internal contacts of the temperature switch W2 are open, and the relay J2 will not be energized, then the buzzer B will not be energized and make a sound, indicating that the liquid in the distillation box has not dried up; when the distillation process is abnormal (when the temperature is higher than about 101°C), the internal contacts of the temperature switch W2 are closed, and the relay J2 will be energized, and its control power input terminal and the normally open contact terminal will be closed, then the buzzer B will be energized and make a sound, indicating that the liquid in the distillation box has dried up, and the staff can turn off the power of the electric heating plate in time. (8) After the condensed water essential oil enters the outer shell and remains stationary for about one minute, the density of the essential oil is lighter than that of water, so it will float on the water surface. After the staff turns on the power switch SN corresponding to the solenoid valve DC7 (a water tank is placed under the liquid outlet pipe 65 in advance), the solenoid valve DC7 (a manual valve can also be used) is electrically opened, and the water in the outer shell will flow into the water tank. After all the water has flowed out, the power switch of the power solenoid valve DC7 is turned off, and then the water tank is moved away and the finished product tank is placed under the liquid outlet pipe 65. After the power switch SN corresponding to the solenoid valve DC7 is turned on again, the essential oil will all flow into the finished product tank, completing the entire work process (finally turn off all power switches).
