Abstract
Description
Technical Field
[0001] This application relates to the technical field of distillation and extraction equipment, and particularly relates to a distillation and extraction device. Background Art
[0002] Simultaneous distillation extraction is a technique used for analyzing and extracting raw materials containing volatile and semi-volatile components. It is particularly suitable for extracting volatile flavor components. This method uses steam to carry the target components out of the raw materials, and then combines with organic solvent vapor in a condenser, so that the target components are extracted by the organic solvent and enter the organic phase, and finally condense in the condensation device. Because this method combines distillation and extraction simultaneously, it can extract a large amount of raw materials with a small amount of solvent, concentrate the volatile components, and thus obtain the required target components.
[0003] Specifically, simultaneous distillation extraction is achieved by simultaneously heating the liquid phase of the sample and the organic solvent to boiling. Generally, the material and water are placed in a round-bottom flask, which is connected to one side of the instrument, and another flask is filled with the solvent (or extraction agent), which is connected to the other side of the instrument. The two flasks are heated separately (water bath or an electric heating mantle with controllable voltage). The water vapor and the solvent vapor are simultaneously condensed in the instrument. Water and the solvent are immiscible and are separated in the U-shaped tube of the instrument and flow into the flasks on both sides respectively. Distillation and extraction are carried out simultaneously, and only a small amount of solvent is needed to extract a large amount of samples, and the aroma components are concentrated.
[0004] As can be seen from the foregoing, in the prior art, the material is heated while immersed in a solution (such as water). However, for some materials, for example, the aroma generated by heating while immersed in a solution may be different from the aroma generated by heating without being immersed in a solution. And the existing distillation and extraction devices basically do not have a dedicated "steaming" method, so it is difficult to use the existing distillation and extraction devices to realize the process of steaming the material.
[0005] At the same time, when the material is heated and boiled while immersed in a solution (such as water), many other chemical reactions may occur. And the components of the material that are easily soluble in the solution will remain in the aqueous solution in large quantities. In addition, the material attached to the inner wall of the flask is heated too much, resulting in uneven heating of the material. Summary of the Utility Model
[0006] The purpose of the embodiments of this application is to provide a distillation and extraction device, which can heat the material by wet steaming, and can make the material heated more evenly, which helps to improve the extraction efficiency.
[0007] A distillation extraction device provided by the present application includes a distillation flask, an extractant flask, a condenser, and a U-shaped tube. The distillation flask is provided with a distillation port, and a porous partition for carrying a sample is arranged inside the distillation flask. The extractant flask is provided with an extraction port. The condenser includes a cooling medium pipeline and a condensation pipeline. The cooling medium pipeline is used to cool the condensation pipeline. The condensation pipeline includes a condensation inlet located above and a condensation outlet located below; the condensation inlet is simultaneously communicated with the distillation port and the extraction port. The U-shaped tube is located below the condenser and communicated with the condensation outlet. Two ends of the U-shaped tube are provided with an A outlet and a B outlet. The A outlet is communicated into the distillation flask, and the B outlet is communicated into the extractant flask.
[0008] In an implementable solution, the distillation flask includes a lower bottle body and an upper bottle body that are separable and hermetically spliceable.
[0009] In an implementable solution, the distillation flask includes a hose clamp. After the lower bottle body and the upper bottle body are butted, the hose clamp is sleeved at the butting seam of the lower bottle body and the upper bottle body. By tightening or loosening the hose clamp, hermetic splicing or separation of the lower bottle body and the upper bottle body is correspondingly achieved.
[0010] In an implementable solution, the porous partition is fixedly arranged inside the lower bottle body of the distillation flask, and the porous partition and the lower bottle body are of an integrally formed structure.
[0011] In an implementable solution, the porous partition is fixedly arranged inside the upper bottle body of the distillation flask, and the porous partition and the lower bottle body are of an integrally formed structure.
[0012] In an implementable solution, the porous partition is installed inside the lower bottle body or the upper bottle body of the distillation flask in a detachable manner.
[0013] In an implementable solution, the inner wall of the lower bottle body is provided with a first protrusion distributed in a surrounding manner, and the porous partition is placed inside the lower bottle body and placed on the first protrusion.
[0014] In an implementable solution, the inner wall of the upper bottle body is provided with a plurality of second protrusions distributed at intervals in a surrounding manner. The second protrusions are provided with grooves facing upward. The edge of the porous partition is provided with a plurality of protrusions distributed at intervals in a surrounding manner. The number and distribution form of the protrusions are the same as those of the second protrusions. During use, the protrusions of the porous partition pass through the gaps between adjacent second protrusions from bottom to top, and then the porous partition rotates a predetermined angle and drops, so that the protrusions are stuck in the grooves.
[0015] In an implementable solution, the distillation extraction device further includes a reflux extension pipe. One end of the reflux extension pipe is communicated with the A outlet of the U-shaped tube, and the other end is communicated into the distillation flask and extends below the porous partition.
[0016] In an implementable solution, the porous partition is provided with a dedicated through-hole for the reflux extension tube to pass through, and the dedicated through-hole is relatively close to the edge of the porous partition.
[0017] Compared with the prior art, the technical solution of the present application at least includes the following beneficial effects:
[0018] When the distillation extraction device of the present application is in use, during the entire distillation extraction process, due to the presence of the porous partition, the process of "steaming" can be simulated, and by wet-steaming the material, the odor substances in the wet-steamed state of the material can be obtained.
[0019] Since the material is no longer soaked in the solution for cooking, the irrelevant reactions with the solution can be reduced. At the same time, the material is on the porous partition and no longer contacts the inner wall of the distillation flask, and the problem of excessive local heating of the material can be basically eliminated, improving the uniformity of heat reception of the material.
[0020] In a further solution, the distillation extraction device further includes a condensing solution reflux extension tube extending below the porous partition. The reflux extension tube directly guides the refluxed condensing solution below the porous partition without dripping onto the material, and basically no significant temperature drop phenomenon occurs, thereby helping to accelerate the extraction efficiency.

[0040] The following further explains the technical solution of the present application in conjunction with specific embodiments. However, it should be noted that the specific embodiments are only a specific implementation and interpretation of the essence of the technical solution of the present application, and should not be understood as a limitation on the protection scope of the present application.
[0041] The reagents and instruments used in the embodiments can all be purchased from commercially available products, and the detection methods are conventional methods well known in the art.
[0042] As Figure 1 shown, this embodiment provides a distillation extraction device, including a distillation flask 1, an extraction agent flask 2, a condenser 3 and a U-shaped tube 4.
[0043] Among them, the distillation flask 1 is provided with a distillation port, and a porous partition 11 for carrying samples is arranged inside the distillation flask 1. The distillation flask 1 is used to hold the solution for distillation, such as water. The extraction agent flask 2 is provided with an extraction port, and the extraction agent flask 2 is used to hold the extraction agent (or solvent), and the extraction agent and the solution (water) are generally immiscible.
[0044] The condenser 3 includes a cooling medium pipeline 31 and a condensation pipeline 32. The cooling medium pipeline 31 is used to cool the condensation pipeline 32. The condensation pipeline 32 includes a condensation inlet located above and a condensation outlet located below. The condensation inlet is simultaneously connected to the distillation port and the extraction port. The U-shaped tube 4 is located below the condenser 3 and is connected to the condensation outlet. The two ends of the U-shaped tube are provided with an A outlet and a B outlet. The A outlet is connected to the inside of the distillation flask 1, and the B outlet is connected to the inside of the extractant flask 2.
[0045] For example, before performing distillation extraction, water for distillation is filled in the distillation flask 1, and the liquid level is lower than the porous partition 11. And materials (or samples) are placed on the porous partition 11, and an extractant is filled in the extractant flask 2. At the same time, a cooling medium (such as cooled water) is circulated through the cooling medium pipeline 31 of the condenser 3.
[0046] After the distillation extraction starts, the distillation flask 1 is heated to boiling, so that the water in the distillation flask 1 boils and evaporates. The boiling water vapor rises through the porous partition 11 to perform wet distillation on the materials. The water vapor carries the odor substances in the materials and continues to rise and enters the condensation pipeline 32 of the condenser 3. At the same time, the extractant flask 2 is also heated (such as water bath heating) to form extractant vapor, which also continues to rise and enters the condensation pipeline 32 of the condenser 3. The water vapor and the extractant vapor are mixed in the condensation pipeline 32 and exchange heat with the cooling medium pipeline 31, so that the water vapor and the extractant vapor are condensed and enter the lower U-shaped tube 4 from the condensation outlet of the condensation pipeline 32. At the same time, because the solubility of the odor substances in the extractant is much greater than that in water, the odor substances are extracted into the extractant. And because water and the extractant are immiscible, they are separated in the U-shaped tube 4 of the instrument. The condensed water flows back to the distillation flask 1 through the A outlet of the U-shaped tube 4, and the condensed extractant flows back to the extractant flask 2 through the B outlet of the U-shaped tube 4.
[0047] During the whole distillation extraction process, due to the existence of the porous partition 11, the process of "steaming" can be simulated in this way. Through the wet distillation of the materials, the odor substances in the wet distillation state of the materials can be obtained.
[0048] Since the materials are no longer soaked in the solution for cooking, the irrelevant reactions with the solution can be reduced. At the same time, the materials are on the porous partition 11 and no longer contact the inner wall of the distillation flask 1, and the problem of excessive local heating of the materials can be basically eliminated, improving the uniformity of heating of the materials.
[0049] In this embodiment, as Figure 2 and Figure 3 shown, the distillation flask 1 of the distillation extraction device includes a lower bottle body 12 and an upper bottle body 13 that can be separated and hermetically joined. Among them, the separable lower bottle body 12 and upper bottle body 13 are convenient for cleaning the flask.
[0050] In this embodiment, as Figure 2 and Figure 3 shown, the distillation flask 1 may include a hose clamp 14. After the lower bottle body 12 is docked with the upper bottle body 13, the hose clamp 14 is sleeved at the docking seam of the lower bottle body 12 and the upper bottle body 13. By tightening or loosening the hose clamp 14, the sealed fitting or separation of the lower bottle body 12 and the upper bottle body 13 is correspondingly achieved.
[0051] In this embodiment, as Figure 4 shown, the porous partition 11 may be fixedly arranged in the lower bottle body 12 of the distillation flask 1, and the porous partition 11 and the lower bottle body 12 are of an integrally formed structure. After separating the lower bottle body 12 from the upper bottle body 13, the material can be placed on the porous partition 11.
[0052] In this embodiment, as Figure 5 shown, the porous partition 11 may be fixedly arranged in the upper bottle body 13 of the distillation flask 1, and the porous partition 11 and the lower bottle body 12 are of an integrally formed structure. The material can be directly put onto the porous partition 11 from the distillation opening of the distillation flask 1.
[0053] In this embodiment, as Figure 6 and Figure 8 shown, the porous partition 11 may be installed in the lower bottle body 12 or the upper bottle body 13 of the distillation flask 1 in a detachable manner. The detachable porous partition 11 is more convenient for cleaning.
[0054] In this embodiment, as Figure 6 shown, the inner wall of the lower bottle body 12 may be provided with a circumferentially distributed first protrusion 121, and the porous partition 11 is placed in the lower bottle body 12 and rests on the first protrusion 121. After separating the lower bottle body 12 from the upper bottle body 13, the porous partition 11 can be placed on the first protrusion 121 of the upper and lower bottle bodies 12.
[0055] In this embodiment, as Figure 7 and Figure 8 shown, the inner wall of the upper bottle body 13 may be provided with a plurality of second protrusions 131 distributed at intervals in a circumferential manner, and the second protrusions 131 are provided with upward grooves 132. The edge of the porous partition 11 is provided with a plurality of protrusions 111 distributed at intervals in a circumferential manner, and the number and distribution form of the protrusions 111 are the same as those of the second protrusions 131. During use, the protrusions 111 of the porous partition 11 pass upward through the gaps between adjacent second protrusions 131, and then the porous partition 11 rotates by a predetermined angle and drops, so that the protrusions 111 are snapped into the grooves 132.
[0056] In this embodiment, as Figure 9As shown, the distillation extraction device may further include a reflux extension pipe 5, one end of which is communicated with the A outlet of the U-shaped pipe 4, and the other end is communicated into the distillation flask 1 and extends below the porous partition 11. Since the refluxed condensed solution (such as condensed water) is much lower in temperature than the water vapor, if it drips onto the material being heated, it will cause the temperature to drop during the wet distillation process, slowing down the overall extraction time. However, the reflux extension pipe 5 in this embodiment enables the refluxed condensed solution to be directly guided below the porous partition 11 without dripping onto the material, and basically no significant temperature drop phenomenon will occur, thus helping to accelerate the extraction efficiency.
[0057] In this embodiment, as Figure 10 shown, the porous partition 11 may be provided with a special through hole 112 for the reflux extension pipe 5 to pass through, and the special through hole 112 is relatively close to the edge of the porous partition 11. The reflux extension pipe 5 near the edge can also, to a certain extent, weaken the temperature influence on the wet distillation process.
[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present application.
