Description

Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to a coffee essential oil extraction device used for skin care products. Background Art

[0002] Coffee essential oil is a liquid oil extracted from coffee berries. It has powerful antioxidants called chlorogenic acid. Antioxidants play an important role in slowing down the aging process of the skin. When used as a formula in skin care products, it can rejuvenate the skin, tighten the skin, reduce the appearance of wrinkles, and significantly improve the texture and firmness of the facial skin. In addition, coffee essential oil has the same pH value as human skin and contains enzymes that stimulate detoxification and help cleansing, making it an ideal ingredient for any skin care formula. It can treat acne-prone or problematic skin after application.

[0003] The extraction of coffee essential oil mainly includes three processes: raw material processing, volatile oil extraction, and essential oil separation (for specific background, see the website link https: / / b2b.baidu.com / q / aland?q=766E7E0177621A0405280168706D1B1C083E7A05&id=qideb164eb3b784c9c9e3fe4782ad0d5e13&answer=5719280416505360266&utype=2). During specific production, the coffee fruits are washed and roasted and put into a distillation kettle. Then, an appropriate amount of water is added. Through heating and steam distillation, water vapor and volatile oil after distillation enter the distillation tube, and then the cooled volatile oil is collected to obtain a mixture of water and volatile oil (located in a liquid tank). Since the specific gravity of water is greater than that of volatile oil, after the water and volatile oil in the liquid tank are separated, coffee essential oil is obtained through the essential oil separation process. In the entire process of preparing coffee essential oil, volatile oil extraction is the most critical step. In the prior art, after roasting, coffee berries are put into the distillation kettle. During the entire distillation process, due to lack of stirring, it is not conducive for the volatile oil and water vapor in the coffee berries at the lower layer of the distillation kettle to enter the distillation tube together (not conducive to the mixing of water and coffee berries and the precipitation of volatile oil), so it will have an adverse effect on the preparation efficiency of volatile oil, and will more or less reduce the preparation rate of volatile oil. In addition, in the current separation of water and volatile oil, the staff usually manually adjusts the height of the liquid inlet pipe of the liquid pump so that the lower end of the liquid inlet pipe is located at the lower end of the volatile oil and above the water layer, so as to ensure that the volatile oil in the liquid tank is extracted as much as possible for the subsequent separation of essential oil process. The above operation method has a major drawback. Since the volatile oil is opaque, if the staff adjusts the height of the liquid inlet pipe too high, it is impossible to ensure that as much volatile oil as possible is extracted (so in actual production, the staff adjusts the height of the liquid inlet pipe from high to low many times according to experience). On the contrary, if the height of the liquid inlet pipe is adjusted too low, it will cause too much water to be extracted and mixed into the volatile oil, which will have an adverse effect on the subsequent essential oil separation process. In addition, the staff's repeated adjustment of the height of the liquid inlet pipe will also cause inconvenience to them, and is not conducive to improving work efficiency (and it still cannot effectively prevent water from mixing into the volatile oil and entering the next work process). In summary of the above factors, it is particularly necessary to provide a coffee essential oil extraction equipment that is mainly used in the volatile oil extraction process, can improve the oil yield of volatile oil and prevent water from entering the essential oil separation process as much as possible. Utility Model Content

In application, the volatile oil can be distilled and precipitated by stirring the coffee fruit, which relatively improves the oil yield of the volatile oil and reduces the oil yield time. After the cooled water and volatile oil mixture enters the liquid tank, the staff only needs to adjust the height of the water inlet pipe of the liquid pump once to effectively extract the cooled volatile oil. On this basis, the coffee essential oil extraction device for skin care products also minimizes the mixing of water into the volatile oil and enters the essential oil separation equipment.

[0019] Figure 1 , 2As shown in, the novel invention is mainly used in the volatile oil extraction process, and the prepared volatile oil is used for further processing in the separation essential oil equipment (the separation essential oil equipment is an existing mature technology, and this application will not be repeated, nor will it provide any protection for the technical solution of the separation essential oil equipment). The specific production process of this application is as follows. (1): After the power input end of the power module W1, the 3rd and 4th pins of the power module W1 output a stable DC 12V power supply; the staff washes and roasts the coffee fruits and puts them into the feed bin 1, and turns on the power switches of the vibration motor M3 and the solenoid valve DC2. In this way, under the action of the vibration motor M3, the coffee fruits enter the distillation kettle 2 through the solenoid valve DC2 with the valve core opened, and then turns on the power switch of the solenoid valve DC1. The solenoid valve DC1 is electrically opened, so that tap water enters the distillation kettle 2. After the amount of tap water entering the distillation kettle is sufficient and the coffee fruits have all entered the reactor 2, the staff turns off the power switches of the vibration motor, the solenoid valves DC1, and DC2. (2): After turning on the power switches of the electric heating tubes RT and the electric stirring mechanism M2, the five electric heating tubes RT are energized to heat the water and coffee berries in the distillation kettle 2. The water vapor and the volatile oil after distillation enter the distillation tube (the pipe connecting the distillation kettle and the condensation structure). After the electric stirring mechanism M2 is energized, its stirring rod 7 stirs the water and coffee berries. Since the coffee berries are stirred by the electric stirring mechanism, the distillation and precipitation of volatile oil are facilitated, which relatively increases the oil yield of volatile oil and reduces the oil yield time (after the distillation process is completed, turn off the power switches of the electric heating tubes RT and the electric stirring mechanism M2). (3): After distillation, water and volatile oil enter the condenser tube 101 of the condensing mechanism. After opening the valve of the tap water pipe, cooling water enters the shell 102 through the water inlet pipe 103 of the shell 102, and then flows out from the water outlet pipe 104. The cooling water will cool the mixed gas in and out of the condenser tube 101 during the inflow and outflow. After turning on the power switches of the six sets of semiconductor refrigeration mechanisms M4 (after turning on the power switch of the solenoid valve DC3, the solenoid valve DC3 is powered on and the valve core is opened. After turning on the power switch of the vacuum pump M5, it is powered on and works to actively draw the mixed gas output from the distillation kettle 2 into the condensing mechanism), the six sets of semiconductor refrigeration mechanisms M4 absorb heat from the shell. In this way, under the combined action of the inflow and outflow of cooling water, the mixed gas continuously entering from the upper end of the condenser tube 101 can be cooled into water and volatile oil and output to the liquid tank 4 through the lower end of the condenser tube 101. After the subsequent condensation of the mixed gas is completed, the power switches of the six sets of semiconductor refrigeration mechanisms M4, the vacuum pump M5 and the solenoid valve DC3 are turned off.(4): All the volatile oils in the coffee berries in the still 2 are condensed into liquid and enter the liquid tank 4 together with water to settle for a period of time (the sealing plate 5 is subsequently opened to take out the coffee berry residue, and then the sealing plate is re-secured). The staff turns on the power switch S and moves the upper end of the regulating tube 91 up or down along the branch pipe (because the liquid pump has a flexible rubber tube with a length margin at the liquid inlet end, the height of the regulating tube 91 can be easily adjusted up or down). When the metal sheet T does not touch the water layer (water has a high specific gravity and the volatile oil is located on its upper layer), since the volatile oil is not conductive, the resistance between the two metal sheets T is infinite. In this way, the 12V power supply enters the base of the transistor Q through the resistor R, which is lower than 0.7V, and the transistor Q will not be turned on. The fact that the buzzer does not receive electricity and make sounds indicates that the metal sheet T has not yet touched the water layer; when the lower end of the metal sheet T touches the water layer, since water is conductive, the resistance between the two metal sheets T becomes smaller, so that the 12V power supply enters the base of the transistor Q through the resistor R and is higher than 0.7V, and the transistor Q will turn on the collector to output a low level and enter the negative power input terminal of the buzzer B. The fact that the buzzer B receives electricity and makes sounds indicates that the metal sheet T touches the water layer, and then the staff slightly adjusts the adjusting tube 91 upwards, so that the lower end of the metal sheet T just no longer touches the upper layer of water (the buzzer B no longer sounds, and the bolt 93 is tightened after adjustment, the left end of the bolt 93 is in close contact with the adjusting tube, and the adjusting tube is at a fixed height), to prevent the subsequent liquid pump M1 from working to extract volatile oil. (5): After turning on the power switch of the liquid pump M1, it will be powered on to extract the volatile oil located above the water layer in the liquid tank 4 into the refrigerated distillation tank of the essential oil separation equipment. After the volatile oil is extracted, turn off the power switch of the liquid pump M1 (the volatile oil enters through the liquid inlet 94 at the lower left end of the regulating tube and is discharged through the liquid outlet 95).

[0020] Figure 1 , 2 As shown above, the present invention is mainly used in the volatile oil extraction process, and the prepared volatile oil is used for further processing in the essential oil separation equipment, which is beneficial to the distillation of the volatile oil, relatively improves the volatile oil yield and reduces the oil yield time; the staff only needs to adjust the height of the regulating tube up and down once, and there is no need to adjust it again later. The subsequent liquid pump can effectively extract the cooled volatile oil, and also minimizes the mixing of water into the volatile oil and enters the essential oil separation equipment (each time the volatile oil is extracted, in order to prevent the extraction of water, there is actually a relatively small amount of volatile oil located on the water layer in the liquid tank, which does not affect normal use, and part of the volatile oil can be discharged in the next production; after the subsequent staff opens the manual valve 93, the water in the liquid tank 4 flows out, and when the outflowing water just contains volatile oil, the staff can close the valve 93 in time). Figure 2As shown in the figure, the electric heating plate RT (electric heating mechanism) is a finished product of dry-burning electric heating tube with a power of 1500W and a brand of COOKRHOUL / Cool Kao; the solenoid valves DC1 and DC3 are normally closed valve core solenoid valves with a power of 2W; the solenoid valve DC2 is a normally closed valve core solenoid valve with a power of 5W; the buzzer B is a finished product of DC12V active continuous buzzer of model SFM-27; the power module W1 is a finished product of AC 220V to DC 12V switching power module; the motor of the motor stirring mechanism is a coaxial motor gear reducer with a power of 1.5KW; the semiconductor refrigeration mechanism M4 has a power of 120W per set (its hot end is located on the outside); the vibration The power of the electric motor M3 is 600W; the power of the liquid pump M1 is 500W (some volatile oil can be injected into the volute before work, which is conducive to the rotation of the blades to create a vacuum and extract the volatile oil. In fact, many liquid pumps have liquid left at the liquid inlet end after stopping work, so no addition is needed for secondary work); the resistance value of the resistor R is 100Ω; the transistor Q is a 9013 NPN transistor; the power of the electric vacuum pump M5 is 50W (it has a motor, a volute, and blades. The motor is installed at the rear outer end of the volute and the shaft is located in the volute. The blades are tightly sleeved on the outside of the front end of the shaft and the blades are located in the volute. The upper and lower ends of the volute are provided with an intake pipe and an exhaust pipe respectively).
