Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction devices, in particular to rosemary oil processing equipment. Background Art

[0002] Rosemary essential oil is a colorless to light yellow liquid. It is a long-standing spice widely used in perfume, cosmetics, medical treatment, soap and air freshener. Rosemary essential oil can regulate greasy and unclean skin, promote blood circulation and stimulate hair regeneration; it can reduce skin congestion, edema and swelling, can astringe the skin and improve dandruff; it can relieve menstrual pain, diuresis, lose weight, and has health care effects on the gastrointestinal tract, heart, lung, liver and gallbladder; it also has the effects of lowering blood pressure, regulating anemia, refreshing, refreshing the brain and restoring central nervous system vitality. The extraction methods of rosemary essential oil mainly include steam distillation, solvent extraction, ultrasonic extraction, supercritical carbon dioxide extraction, microwave extraction, enzymatic hydrolysis, microcapsule aqueous two-phase extraction and so on. Among them, the solvent extraction method has the advantages of high extraction rate (extraction rate is 92.38%), good stability, high purity of extract, relatively convenient operation and relatively low cost, so this method is widely used in actual production. Specifically, one or more organic solvents selected from petroleum ether, n-hexane, ethyl acetate, acetone, ethanol, etc. are used as extraction solvents to dissolve the active substances in the dried and crushed rosemary essential oil extraction raw material (rosemary grass), and then the extraction solvent is evaporated by evaporation to obtain a finished rosemary essential oil product.

[0003] Although the existing solvent extraction equipment meets the production needs to a certain extent, it is affected by the structure and still has the following technical disadvantages. First, the solvent generally extracts effective substances under a static state at room temperature. When the temperature in the production area is relatively low and the solvent and the extracted raw materials are not affected by movement, the time for the solvent to dissolve the rosemary essential oil will be relatively increased, which is not conducive to improving work efficiency. Second, after the rosemary essential oil in the raw material is dissolved, it needs to be filtered separately with a filtering device, and then the solvent is evaporated by an evaporation device (the liquid after the solvent is evaporated is rosemary essential oil) and the liquid solvent is obtained by a condensation device for reuse. The above equipment is generally an independent working mode, which will bring inconvenience to the operation of the staff and is not conducive to improving work efficiency. In summary, it is particularly necessary to provide a rosemary oil processing equipment that is compact in structure, easy to use, and can improve work efficiency. Utility Model Content

The handles of all power switches are located outside the multiple openings at the front end of the component box.

[0018] Figure 1 , 2As shown, the new model integrates multiple mechanisms together, and has the advantages of compact structure, small installation space and easy use. After the AC 220V power supply enters the power input terminal 1 and 2 of the power module W1, its 3 and 4 pins will output a stable DC 12V power supply to the power input terminal of the power switch connected to the five solenoid valves and the semiconductor refrigeration mechanism. The specific working process of the new model is as follows. (1) The staff puts the pre-dried and crushed raw materials into the raw material bin 3, turns on the power switches of the motor reducer 33 and the solenoid valve DC5 (the valve core of the solenoid valve DC5 is open) of the electric rotary valve sub-mechanism, and then the rotating shaft of the motor reducer 33 drives the rotating plate 32 to rotate and continuously input the raw materials in the raw material bin 3 into the reaction box 61. After the feeding is completed, the staff turns on a power switch corresponding to the solenoid valve DC4 at the same time, and the solenoid valve DC4 is opened by the electric valve core, so that the solvent in the solvent box 1 (one or more of petroleum ether, n-hexane, ethyl acetate, acetone, ethanol, etc.) enters the reaction box 62. After all the solvents enter the reaction box 62, the power switches of the solenoid valve DC4, the solenoid valve DC5 and the motor reducer 33 are turned off. (2) Turn on the power switches of the electric heating tube ART1 and the electric stirring sub-mechanism M1. After the electric stirring sub-mechanism M1 is powered on, it stirs the solvent and raw materials in the reaction box. After the electric heating tube ART1 is powered on, it heats the raw materials and solvent in the reaction box. When the temperature in the solvent box is lower than a certain temperature (for example, ethanol is used as the solvent and the temperature is lower than 70°C), the internal contacts of the temperature switch AK2 are closed. In this way, the electric heating tube ART1 is powered on to heat the substances in the solvent box. When the temperature in the solvent box is higher than a certain temperature (for example, ethanol is used as the solvent and the temperature is higher than 70°C), the internal contacts of the temperature switch AK2 are open. In this way, the electric heating tube ART1 loses power and no longer generates heat. Through the above, the new type can dissolve the effective essential oil substances in the raw materials through the solvent under the condition of being constant and lower than the evaporation temperature of the solvent; the above time is generally about 20 minutes. After the dissolution process is completed, turn off the power switches of the electric heating tube ART and the electric stirring sub-mechanism M1. (3) The staff turns on the power switch of the solenoid valve DC2, so that the essential oil mixture fully dissolved by the solvent is filtered through the filter 52 and enters the evaporation box 41. After the filtration is completed, the power switch of the solenoid valve DC2 is turned off (after all subsequent work is completed, the sealing plate 53 can be opened, the effective ingredients dissolved on the filter are taken out and the raw materials are cleared after filtration, and then the filter is reset and installed).(4) Turn on the power switches of the electric heating tube RT and the solenoid valve DC3 (the valve core of which is powered on is open). After the electric heating tube RT is powered on, it heats the raw materials and solvent in the evaporation box 41. When the temperature in the solvent box is lower than a certain temperature (for example, ethanol is used as the solvent and the temperature is lower than 95°C), the internal contacts of the temperature switch K1 are closed. In this way, the electric heating tube RT is powered on to heat and evaporate the substances in the evaporation box 41. When the temperature in the solvent box is higher than a certain temperature (for example, ethanol is used as the solvent and the temperature is lower than 95°C), the internal contacts of the temperature switch K1 are open. In this way, the electric heating tube RT is no longer powered on to heat and heat the substances in the evaporation box 41. Through the above, the present invention can evaporate the solvent from the mixture at a constant temperature. The above time is generally about 30 minutes. After the evaporation process is completed, turn off the power switches of the electric heating tube RT and the solenoid valve DC3. (5) About 1 minute before step (4), the staff turns on the power switch of the semiconductor refrigeration mechanism MN, and the semiconductor refrigeration mechanism cools the outer box 8 (the outer box 8 is lower than the solvent condensation temperature, and the solvent is cooled to liquid). After the pressure evaporates, the solvent component flows into the upper end of the cooling pipe 82 in gaseous form and flows out of the lower end in liquid form into the solvent recovery tank. After the solvent is completely condensed and recovered (generally 25 minutes), the staff turns off the power switch of the semiconductor refrigeration mechanism MN. (6) The staff turns on the power switch of the solenoid valve DC1, and the electric valve core of the solenoid valve DC1 opens. The rosemary essential oil after the solvent is evaporated flows into the rosemary oil finished product tank. Finally, the power switch of the solenoid valve DC1 is turned off to complete the whole process. Through all the above processes, when the new type is specifically produced, the electric rotary valve sub-mechanism can effectively output the raw materials to the dissolution mechanism. The dissolution mechanism can reduce the time for the solvent to dissolve the raw materials through electric heating and stirring. And through a simple power switch operation, the raw materials after dissolution can complete the work process of filtering by the filtering mechanism, evaporating by the evaporating mechanism, and condensing the solvent by the condensing mechanism, which brings convenience to the staff and improves work efficiency.

[0019] Figure 2 As shown, the electric heating plates RT and ART1 are finished products of dry-burning electric heating tubes with a power of 1500W and a brand of COOKRHOUL / Cool Kao; the solenoid valves DC1, DC2, DC3, DC4, and DC5 are normally closed valve core solenoid valves with a power of 2W; the power module W1 is a finished product of an AC 220V to DC 12V switching power supply module; the temperature switches K1 and K2 are finished products of 70°C and 95°C snap-action normally closed contact temperature switches of model KSD301 respectively; the motor reducer is a coaxial motor gear reducer with a power of 100W and its shaft rotates at 300 revolutions per minute; each set of the semiconductor refrigeration mechanism MN has a power of 120W (its cold end is close to the outer box body and the hot end is located on the outside); the electric stirring sub-mechanism M1 has a power of 2KW.
