Description

Technical Field

[0001] The present invention relates to the technical field of distillation extraction, and particularly relates to an extraction device and method for angelica compound essential oil. Background Art

[0002] Cosmetics are mainly formulated with essential oils such as angelica essential oil, pogostemon cablin essential oil, chuanxiong rhizome essential oil, wild chrysanthemum essential oil, licorice essential oil, and cyperus rotundus essential oil. The extraction of essential oils uses plant branches, leaves, flowers, fruits, etc. as raw materials. After cleaning, screening, cutting, or grinding, etc., and then through operations such as distillation, water-oil separation, and purification, the effective essential oil components are finally obtained.

[0003] In the prior art, during distillation, the material is mixed with water and heated for evaporation. The volatile components in the material need to first precipitate and then volatilize, and will not volatilize simultaneously when heated. It is necessary to heat the mixture for a period of time. At the same time, to improve the extraction rate and ensure that enough volatile components can be carried, it is necessary to heat an excessive amount of water. A large amount of water vapor needs to be condensed and cooled, resulting in energy waste. At the same time, it also increases the workload of water-oil separation, and the existing distillation method needs to be upgraded.

[0004] In the prior art, the problem of excessive water vapor and energy waste during the distillation process needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is, in view of the above-mentioned technical deficiencies, to provide an extraction device and method for angelica compound essential oil applicable to the raw material level of cosmetics, which solves the problem of excessive water vapor and energy waste during the distillation process in the prior art.

[0006] The technical solution adopted by the present invention is: to provide an extraction device for angelica compound essential oil, including:

[0007] Tanks, there are several of them. The upper part of the tank has a condensation space, and the lower part of the tank has a water storage space. Several of the tanks are arranged vertically in sequence. There is heat conduction between the water storage space and the condensation space of the adjacent upper and lower tanks. The upper part of the condensation space is communicated with an exhaust pipe;

[0008] Evaporation trays, there are several of them. Each tank is provided with an evaporation tray. The evaporation tray is used to accommodate the material. The evaporation tray has a heating device. The evaporation tray is located below the condensation space;

[0009] Liquid supply pumps, there are several of them. Each tank is provided with a liquid supply pump. The liquid inlet end of the liquid supply pump is communicated with the water storage space, and the liquid outlet end of the liquid supply pump is communicated with the inside of the evaporation tray.

[0010] To further optimize this technical solution, the upper part of the tank body has an outward extension cap protruding upward. The interior of the outward extension cap is the condensation space. The middle part of the lower end of the tank body has a slot that is inserted and matched with the outward extension cap. Two adjacent tank bodies up and down are connected by inserting and connecting the slot and the outward extension cap to form heat conduction.

[0011] To further optimize this technical solution, it further includes:

[0012] Condensation plates, there are several of them, and the condensation plates are vertically arranged in the condensation space.

[0013] To further optimize this technical solution, the evaporation pan is located below the condensation plates.

[0014] To further optimize this technical solution, it further includes:

[0015] A condensation box, the interior of which is used to hold water, is inserted and arranged on the outward extension cap of the tank body at the uppermost end. The condensation box has a water outlet pipe, and the lower end of the water outlet pipe communicates with the water storage space of the tank body at the lowermost end.

[0016] To further optimize this technical solution, the side wall of the tank body has a feed pipe, and the feed pipe communicates with the upper part of the evaporation pan for feeding materials to the evaporation pan. The side wall of the tank body also has a discharge pipe, and the discharge pipe communicates with the evaporation pan for discharging slag.

[0017] To further optimize this technical solution, the side wall of the tank body has a water replenishing pipe, and the water replenishing pipe communicates with the water storage space.

[0018] A method for using an angelica composite essential oil extraction device is also proposed. The materials are distilled using the angelica composite essential oil extraction device, and it includes the following steps:

[0019] S1, Prepare materials on the evaporation pan and prepare water in the water storage space;

[0020] S2, First start the distillation treatment of the lowermost tank body, turn on the liquid supply pump of the lowermost tank body, add water to the evaporation pan, and the heating device heats the evaporation pan;

[0021] S3, During the distillation treatment, water vapor and volatile substances in the materials rise to the condensation space, and after partial condensation, they fall back into the evaporation pan or the water storage space;

[0022] S4, Sequentially start the distillation treatment of the tank bodies from bottom to top, and use the heat in the lower tank body to preheat the water in the water storage space of the adjacent upper tank body.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The liquid supply pump supplies water into the evaporation pan for heating and evaporation. In the condensation space, part of the water vapor is condensed and recovered, and it falls back into the evaporation pan and is reused to become water vapor again. This can reduce the water consumption, thereby reducing the total amount of water vapor and the workload of subsequent water-oil separation.

[0025] 2. The water vapor releases heat when condensed in the condensation space. The heat is conducted to the upper tank body and can preheat the water in the water storage space, which is energy-saving and environmentally friendly. At the same time, there is water stored in the lower part of the water storage space, which can receive part of the refluxed condensed water and avoid waste of essential oil components.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0032] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0033] In addition, in the description of this application, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0034] As Figures 1-3 shown, an Angelica composite essential oil extraction device includes: a plurality of tanks 1, the upper part of the tank 1 has a condensation space 101, the lower part of the tank 1 has a water storage space 102, and the plurality of tanks 1 are arranged in sequence vertically. There is heat conduction between the water storage space 102 and the condensation space 101 of the adjacent upper and lower tanks 1. The upper part of the condensation space 101 is communicated with an exhaust pipe 103; a plurality of evaporation trays 2, each evaporation tray 2 is arranged in each tank 1, the evaporation tray 2 is used to accommodate materials, the evaporation tray 2 has a heating device 201, and the evaporation tray 2 is located below the condensation space 101; a plurality of liquid supply pumps 3, each liquid supply pump 3 is arranged on each tank 1, the liquid inlet end of the liquid supply pump 3 is communicated with the water storage space 102, and the liquid outlet end of the liquid supply pump 3 is communicated with the inside of the evaporation tray 2. The side wall of the tank 1 has a feed pipe 6, the feed pipe 6 is communicated with the upper part of the evaporation tray 2 for feeding materials to the evaporation tray 2, and the side wall of the tank 1 also has a discharge pipe 7, the discharge pipe 7 is communicated with the evaporation tray 2 for discharging slag. The side wall of the tank 1 has a water replenishing pipe 8, and the water replenishing pipe 8 is communicated with the water storage space 102.

[0035] During use, materials can be put into the evaporation tray 2 through the feed pipe 6, and water can be injected into the water storage space 102 and replenished later through the water replenishing pipe 8. The plurality of tanks 1 are distributed vertically, and heat conduction can be carried out between the adjacent upper and lower tanks 1. Different materials can be distilled in different tanks 1 to realize the simultaneous distillation and extraction of multiple essential oils. First, start the distillation process of the lowermost tank 1. The liquid supply pump 3 of the lowermost tank 1 works, pumps water into the evaporation tray 2, and the heating device 201 heats the evaporation tray 2. The components in the materials are separated and volatilized by heat. The water vapor carries the volatile components and rises to the condensation space 101. Part of the water vapor and volatile components are discharged from the exhaust pipe 103 to the next process. Part of the water vapor and volatile components condense into liquid and then fall into the evaporation tray 2, and are evaporated by heat again, improving the utilization rate of water and bringing out more volatile components. The heat in the condensation space 101 is conducted to the water storage space 102 of the adjacent upper tank 1 to preheat the water in the upper water storage space 102, so that the heat can be recycled. At the same time, the upper tanks 1 can be started in sequence for distillation processing to make more efficient use of heat.

[0036] The exhaust of the exhaust pipe 103 can be adjusted according to the specific situation of the volatilization of the components in the synchronous material. Generally, when a large amount of water vapor begins to be generated at the beginning, there is more water vapor and relatively fewer components in the material. In the initial stage, the exhaust of the exhaust pipe 103 can be reduced to make a large amount of water vapor fall back for reuse, so that more volatile components in the material can be precipitated and volatilized. In the middle stage, as the volatile components increase and the utilization of water vapor is relatively sufficient, the exhaust of the exhaust pipe 103 can be increased. In the later stage, as the total remaining amount of volatile components decreases and the proportion of water vapor increases, the exhaust of the exhaust pipe 103 can be reduced, and the water supply of the liquid supply pump 3 can be reduced, so that more volatile components can be volatilized while the total water consumption is significantly reduced. At the same time, the overall process flow is controlled according to the heat resistance of different components. When controlling the exhaust, the internal pressure increase will be obvious. The pressure can be reduced by enhancing the water flow in the water storage space 102 or increasing the water volume to strengthen the condensation.

[0037] The installation and connection control of the feed pipe 6, the discharge pipe 7 and the water replenishing pipe 8 are all conventional technical means, which will not be elaborated in this application. The material can be filled into the evaporation pan 2 through the feed pipe 6. After the distillation is completed, the mixture of slag and water can be discharged through the discharge pipe 7, and then purification and other treatments can be carried out. Water can be replenished into the water storage space 102 through the water replenishing pipe 8, or the water flow can be strengthened to improve the condensation effect.

[0038] Further, the upper part of the tank body 1 has an upwardly protruding extension cap 104, the inside of the extension cap 104 is the condensation space 101, the middle part of the lower end of the tank body 1 has a slot 105 that is inserted and matched with the extension cap 104, and two adjacent tank bodies 1 up and down are connected by inserting and connecting through the slot 105 and the extension cap 104 to form heat conduction. It also includes: a plurality of condensation plates 4, and the condensation plates 4 are vertically arranged in the condensation space 101. The evaporation pan 2 is located below the condensation plates 4.

[0039] When in use, except for the bottom tank body 1 or all tank bodies 1 can adopt an upper convex and lower concave structure, and the upwardly protruding extension cap 104 at the upper end is inserted and matched with the upwardly concave slot 105 structure at the lower end, which is convenient for the installation and connection of the upper and lower tank bodies 1. At the same time, the heat conduction area is increased, and the steam is easy to gather in the condensation space 101. To improve the heat conduction, the heat conduction coefficient, the heat conduction area, the heat dissipation area, etc. can be increased by existing conventional technical means.

[0040] The condensation plate 4 can be a plate-like structure vertically arranged or inclined downwardly arranged in the condensation space 101, and can be connected to the inner wall of the tank body 1 to facilitate the water conduction into the evaporation pan 2 below. The existing condensation filler layer structure can also be adopted and arranged in the condensation space 101 or the extension cap 104, and has a vertical condensation channel inside.

[0041] The condensation space 101 is located in the upper part of the tank body 1. It is not limited to the internal space of the extension cap 104, and the upper space of the tank body 1 can also be the condensation space 101. Of course, it can also specifically refer to the internal space of the extension cap 104.

[0042] Furthermore, it further includes: a condensation box 5, which is internally used to hold water and is inserted and arranged on the extension cap 104 of the uppermost tank body 1. The condensation box 5 has a water outlet pipe 501, and the lower end of the water outlet pipe 501 communicates with the water storage space 102 of the lowermost tank body 1.

[0043] During use, as Figure 2 shown, by adding a condensation box 5 above the uppermost tank body 1, the heat conducted out from the condensation space 101 of the uppermost tank body 1 can be collected and utilized, and the heat is applied to the water in the lowermost tank body 1, effectively realizing heat recovery and utilization.
