Description

Technical Field

[0001] The invention relates to the technical field of fennel volatile oil extraction, in particular to fennel volatile oil extraction equipment. Background Art

[0002] Fennel is a common spice and Chinese herbal medicine. Fennel volatile oil is one of its main active ingredients. The volatile oil content is generally around 1.5%-6%. The main ingredients include trans-anethole (content can reach 60%-78%), which is the main source of the special aroma of fennel volatile oil. There are also ingredients such as limonene, fennel, and γ-terpinene. These ingredients give fennel anti-inflammatory, antibacterial, and analgesic pharmacological effects. For example, in some in vitro experiments and animal model experiments, fennel volatile oil can reduce symptoms such as swelling and pain in inflammatory tissues, and may have potential therapeutic effects on arthritis, skin inflammation, etc. In addition, terpenoid compounds in fennel volatile oil such as anisaldehyde and anise ketone also make important contributions to the flavor and medicinal value of fennel. And fennel can remove fishy smell and greasiness, adding a unique flavor. When making stewed food, fennel is also one of the indispensable spices. When used with star anise, cinnamon, etc., it can make the stewed products taste more rich and mellow. Therefore, fennel can be used not only as a spice for cooking food, but also as a medicinal material. The existing methods for extracting volatile oils mainly include: steam distillation, freezing treatment, chemical separation, chromatography and molecular distillation.

[0003] Existing fennel volatile oil extraction equipment usually uses distillation and ultrasonic extraction for extraction. For example, the prior art publication number CN105535047A discloses an extraction process for fennel volatile oil, fennel soft capsules and their applications. This prior art significantly improves the extraction rate of fennel volatile oil by combining fennel water vapor distillation and solvent dynamic extraction. Another example is a method for extracting fennel volatile oil with a prior art publication number CN104073341A. This prior art uses a dual-frequency ultrasonic method to extract fennel volatile oil. The process is simple, the extraction time is short, the energy consumption is low, and the yield of volatile oil is significantly higher than that of traditional extraction methods, which is suitable for industrial production.

[0004] When the fennel volatile oil extraction equipment in the prior art is used, since the density of fennel is smaller than that of water, a large amount of fennel will float on the water surface when fennel is mixed with water, and during the distillation process, part of the fennel will adhere to the inner wall of the distillation box due to the undulating water, resulting in insufficient mixing of fennel and water, insufficient release of fennel volatile oil, and the need to extend the distillation time, resulting in low extraction efficiency of fennel volatile oil. Based on this, the present invention provides a fennel volatile oil extraction equipment with high extraction efficiency. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a fennel volatile oil extraction device to solve the problem in the prior art that fennel floats on the water surface, sticks to the inner wall of the distillation box and is not fully mixed with water, resulting in insufficient release of volatile oil and low volatile oil extraction efficiency.

[0006] The present invention is achieved through the following technical solutions:

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0043] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0044] See also Figure 1-13 , the present invention provides a technical solution: a fennel volatile oil extraction device, comprising an extraction box 1, wherein a metal extraction box 2 is provided inside the extraction box 1 for placing fennel to be extracted with volatile oil;

[0045] The extraction component 3 is used to extract the volatile oil in fennel. The extraction component 3 includes two sealing blocks 301. An ultrasonic transducer 302 is fixedly penetrated through the top of one of the sealing blocks 301. The ultrasonic transducer 302 is of model Keli The sonic-P4-5028 ultrasonic transducer 302 is a device that can realize the mutual conversion between electrical energy and mechanical energy. When the ultrasonic generator 18 outputs high-frequency alternating current, the piezoelectric ceramic material in the ultrasonic transducer 302 will expand and contract under the action of the electric field. This deformation will cause the surrounding medium (such as air, liquid or solid) to vibrate, thereby generating ultrasonic waves. An ultrasonic generator 18 is arranged behind the ultrasonic transducer 302. The model of the ultrasonic generator 18 is KG-X6. The ultrasonic generator 18 converts the mains electricity into ultrasonic frequency alternating current to provide suitable high-frequency electric energy for the ultrasonic transducer 302. A steam outlet pipe 303 is fixedly penetrated at the top of another sealing block 301. The bottoms of the two sealing blocks 301 are connected to brackets 304. A detachable filter screen 305 is fixedly arranged inside the bracket 304.

[0046] The top of the extraction box 1 is provided with lifting openings 5 ​​having the same number as the sealing blocks 301, and two sealing blocks 301 respectively penetrate the two lifting openings 5. The top of the extraction box 1 is fixed with two electric push rods 6 for driving the sealing blocks 301 to rise and fall. Specifically, the model of the electric push rods 6 is jc35 l35;

[0047] The metal extraction box 2 is fixedly penetrated with a stainless steel tube 7 that is compatible with the metal three-way pipe 403, and a filter screen 8 is fixedly arranged inside the stainless steel tube 7. The stainless steel tube 7 and the two metal three-way pipes 403 are fixedly provided with a solenoid valve 9. Specifically, the solenoid valve 9 is DN15, and the solenoid valve 9 is mainly composed of a solenoid coil and a valve body. When the solenoid coil is energized, a magnetic field is generated, and this magnetic field drives the valve core to move. The change in the position of the valve core changes the channel state inside the valve body, thereby controlling the circulation, cutoff, and direction change of the fluid;

[0048] A heating plate 10 for heating the metal extraction box 2 is fixedly embedded in the inner wall of one side of the bottom of the extraction box 1. Specifically, the model of the heating plate 10 is JRD-G25. A liquid level sensor 11 is fixedly embedded in the inner wall of the metal extraction box 2 away from the stainless steel tube 7. Specifically, the model of the liquid level sensor 11 is LLC210D324-003, which is used to detect the water level in the metal extraction box 2, so as to facilitate timely replenishment of water and fennel for mixing;

[0049] A mounting frame 15 is fixedly provided on the top of the extraction box 1, and a condenser 16 and an oil-water separator 17 are fixedly passed through the rear end of the mounting frame 15. The condenser 16 is connected to the steam outlet pipe 303 and the oil-water separator 17. Specifically, the condenser model is TDH-500L, and the oil-water separator 17 model is R60S-PHC-FG. The condenser 16 takes away the heat of the high-temperature gaseous refrigerant (or other vapor) through a cooling medium (such as water or air) to cause a phase change from gas to liquid. The oil-water separator 17 mainly uses the density difference between oil and water to achieve separation. When the oil-water mixture enters the oil-water separator 17, since the density of oil is less than that of water, the oil will float on the water. Under the action of gravity, the oil layer gradually gathers upward, and the water layer settles downward, so it is convenient to collect the oil.

[0050] When extracting fennel volatile oil, the electric push rod 6 is used to drive the sealing block 301 to pass through the lifting port 5 and insert into the metal extraction box 2, and water is injected into the metal extraction box 2 through the water pump 402 (it is worth noting that the water used for extracting fennel volatile oil is specifically distilled water or purified water), and then the ultrasonic transducer 302 and the ultrasonic generator 18 are used to vibrate and fully mix the fennel particles and the water, so as to promote the release of fennel volatile oil, and the filter screen 305 can press the fennel particles so that the fennel particles are always submerged in the water, so that the fennel particles and the water can be mixed. The water reacts fully to further increase the release of volatile oil from the fennel particles. Then, the ultrasonic transducer 302 and the ultrasonic generator 18 are turned off, and the filter screen 6 is controlled to be moved out of the metal extraction box 2. The metal extraction box 2 is moved below the sealing block 301 with the steam outlet pipe 303. The sealing block 301 is also moved down. The heating plate 10 is used to continuously heat the metal extraction box 2. The fennel particles and water generate water vapor. The volatile oil follows the water vapor and is transported to the condenser 16 through the steam outlet pipe 303. After being cooled by the condenser 16, it is finally separated by the oil-water separator 17 to obtain the volatile oil. In this embodiment, the filter screen 305 is used to limit the fennel particles to prevent the fennel particles from floating on the water surface and the inner wall of the metal extraction box 2 to affect the release of volatile oil, and the enzymatic hydrolysis structure, ultrasonic vibration structure and distillation structure are concentrated together, which can greatly improve the release degree of fennel volatile oil, thereby improving the extraction efficiency of fennel volatile oil, and the metal extraction box 2 moves in the extraction box 1, and the metal extraction box 2 moves a short distance between the enzymatic hydrolysis structure, ultrasonic vibration structure and distillation structure, and the extraction box 1 is sealed, thereby reducing the loss of fennel volatile oil.

[0051] In this embodiment, the present invention further includes a cleaning component 4 for flushing the filter screen 305, wherein the cleaning component 4 includes a plurality of nozzles 401, and the plurality of nozzles 401 are respectively fixed at the bottom of the two sealing blocks 301;

[0052] The tops of the two sealing blocks 301 are fixed with water pumps 402 for water delivery, and the model of the water pumps 402 is ISG50-160. The bottoms of the two water pumps 402 are connected with metal tees 403, and the bottoms of the metal tees 403 penetrate the bottom of the sealing block 301. The water pumps 402 are connected with multiple nozzles 401 through telescopic hoses 404. The condenser 16 and the oil-water separator 17 are both arranged behind the ultrasonic transducer 302 and the water pumps 402;

[0053] When the ultrasonic transducer 302 finishes working, the solenoid valve 9 on the metal three-way pipe 403 is closed, and the solenoid valve 9 connected to the stainless steel pipe 7 is opened. The water pump 402 and the stainless steel pipe 7 are used to suck the water in the metal extraction box 2. The fennel particles are blocked by the filter screen 8 in the stainless steel pipe 7. Then the water is sprayed from the multiple nozzles 401 onto the filter screen 305, and the fennel particles stuck on the filter screen 305 are flushed into the metal extraction box 2 to avoid waste. Similarly, after the distillation of fennel particles and water is completed, the water pump 402 and the nozzle 401 can also be used to continuously flush the fennel particles on the filter screen 305 to prevent the fennel particles from remaining.

[0054] In this embodiment, a discharge port 19 is provided on the top of the extraction box 1 away from the frame mounting frame 15. A detachable crusher 20 and a storage tank 21 are fixedly provided on the top of the extraction box 1 away from the mounting frame 15. Specifically, the crusher 20 is of model GN-20, and the storage tank is of model GN-20. Enzymes are stored in the storage tank 21. The bottom of the crusher 20 is connected to the discharge port 19. The bottom of the storage tank 21 is connected to a discharge pipe 22. The bottom end of the discharge pipe 22 passes through the extraction box 1 and is connected to the stainless steel pipe 7. A solenoid valve 23 is fixedly provided on the discharge pipe 22. Specifically, the solenoid valve 23 is of model DN15, and its principle is the same as that of the above-mentioned solenoid valve 19.

[0055] First, a pulverizer 20 is used to pulverize fennel into fine particles. The pulverized fennel particles fall into a metal extraction box 2 in an extraction box 1. At the same time, solenoid valve 1 9 and solenoid valve 2 23 are opened, and enzymes are added into the metal extraction box 2 to react with the fennel particles, thereby destroying the cell wall structure of the fennel particles and promoting the release of fennel volatile oil.

[0056] In this embodiment, the inner walls of the front and rear sides of the extraction box 1 are fixedly embedded with linear modules 12. Specifically, the model of the linear module 12 is tjkk8610c. The linear module 12 is a device that converts rotary motion into linear motion. It is mainly based on motor drive and precision transmission mechanism to achieve precise linear motion. The two linear modules 12 are detachably fixed to the metal extraction box 2. The inner wall at the bottom of the extraction box 1 is provided with two limit grooves 13 distributed front and back. The front and rear sides of the bottom end of the metal extraction box 2 are fixedly provided with limit blocks 14, and the two limit blocks 14 are respectively slidably arranged in the two limit grooves 13;

[0057] A support frame 24 is fixedly provided at the bottom of the extraction box 1 , and sealed doors 25 are hingedly provided on both sides of the extraction box 1 and the front end of the mounting frame 15 , and a key lock is fixedly embedded on each sealed door 25 .

[0058] The two linear modules 12 can drive the metal extraction box 2 to move stably, so that the position of the metal extraction box 2 can be automatically adjusted, and with the help of the limit block 14 and the limit groove 13, the stability of the movement of the metal extraction box 2 can be further improved. After the extraction of fennel volatile oil is completed, the staff can open the sealing door 25 on the left side of the extraction box 1, loosen the bolts between the metal extraction box 2 and the connecting plate 12, and then remove the metal extraction box 2 for cleaning.

[0059] And in actual use, a control box can be installed on the extraction box 1 to control the operation of the electric push rod 6, solenoid valve 1 9, heating plate 10, linear module 12, condenser 16, oil-water separator 17, crusher 20, storage tank 21 and solenoid valve 23 of the present invention, and a battery for providing electrical energy is arranged inside the control box. At the same time, in order to facilitate remote control, the liquid level sensor 11, ultrasonic generator 18, ultrasonic transducer 302 and water pump 402 can be connected to the control box through a wireless transmission module to realize remote control, and the liquid level sensor 11, ultrasonic generator 18, ultrasonic transducer 302 and water pump 402 are powered by their own batteries. The above technologies are all existing commonly used technologies and will not be further elaborated here.
