Description

Compact one-stop extraction and concentration device
Technical Field
The present invention relates to a compact one-stop extraction and concentration device for extracting and concentrating an extract from an extraction target.
Background
In general, when a medicinal material or food is directly taken, the content of a component effective for the body is small, and thus the component effective for the body is extracted and taken.
In order to extract the components effective for the body, the juice is extracted by squeezing or heating and then extracted, and the juice is extracted by squeezing, but since there are many parts which are not extracted but discarded, most of the components are extracted by heating.
The apparatus for extracting the extract by heating has a disadvantage in that the extraction object is boiled together with water to extract the extract, and a long time is required for heating because of a high heating temperature, so that safety accidents such as burn-in occur.
In order to solve the above-mentioned problems, korean patent publication No. 10-2010-0097499 (2010.9.3 publication) discloses a "extraction and concentration apparatus using steam".
The existing extraction and concentration device using steam comprises: a steam supply source which is communicated with the steam supply pipe and supplies steam; an extractor for obtaining steam supplied from a steam supply source through a steam supply pipe, heating a raw material by the steam, and separating and extracting a specific component from the raw material; a reflux cooler for obtaining the specific component supplied from the extractor and vaporized by heating, condensing the component by cooling, and supplying the condensed component to the extractor again; a stirring concentrator which obtains a supply of two or more specific components extracted by the extractor, mixes them by a stirring device, or obtains a supply of steam from a steam supply source through a steam supply pipe, obtains a supply of the extracted specific components from the extractor, heats the specific components with the steam, and thereby evaporates and concentrates the water of the extracted specific components; and a water purifier which obtains the specific component vaporized by heating from the stirring concentrator and condenses the specific component by cooling. The extraction and concentration device using steam according to the present invention has the effect that the extractor, the concentrator and the stirrer are integrated, so that not only the cost of purchasing by a user can be reduced and the installation space can be saved, but also experimental data can be integrated, thereby facilitating the analysis of results.
However, the conventional extraction and concentration apparatus using steam has problems in that not only a wide installation place is required because the extractor and the stirring concentrator are separated from each other, but also the extraction and concentration work is complicated, for example, in order to move the extract, the extract extracted in the extractor is carried out to the outside and then is transferred to the stirring concentrator again, and the extract is exposed to the outside, so that the extract may be contaminated, and when the scalding extract is moved, a burn accident may occur.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a compact one-stop extraction and concentration apparatus in which an extraction tank and a concentration tank are embodied as one extraction and concentration tank, thereby minimizing installation sites, allowing an extract to move between a condensate tank and the extraction and concentration tank by means of a pressure control unit, preventing contamination due to exposure of the extract to the outside, preventing exposure of relatively hot extract to the outside, and thus preventing occurrence of burn accidents, and facilitating extraction and concentration operations.
Further, it is an object of the present invention to provide a compact one-stop extraction and concentration device which can not only enhance the concentration by foaming an extract with a foamer, but also enhance the foamability by adjusting the amount of foaming with the foamer, and can easily grasp the state of the extract from the outside through a perspective window and a transmission connection portion.
The compact one-stop extraction and concentration device according to an embodiment of the present invention for achieving the above-described object includes: an extraction concentrator that extracts the extract by mixing a solvent with the extraction target and heating, or that concentrates the extracted extract by heating; a condenser that condenses the solvent evaporated by heating in the extraction concentrator; a condensate water tank storing condensate water condensed in the condenser or temporarily storing the extract extracted by the extraction concentrator; a connection pipe connecting the extraction concentrator and the condensate tank so as to move the extract between the extraction concentrator and the condensate tank; a vacuum pump that sucks air through the condensate tank, sucks air through the condenser toward the extraction concentrator, and forms a vacuum in the extraction concentrator in this form; and a pressure control part which transfers the extract from the extraction concentrator to the condensate tank by the pressure of the vacuum pump or changes the pressure acting path of the vacuum pump so as to transfer the extract stored in the condensate tank to the extraction concentrator.
The extraction concentrator may include stirring wings that rotate and stir the extract contained in the extraction concentrator.
The pressure control part may include: a condensed water pipe for supplying condensed water from the condenser to the condensed water tank; a condensation branch pipe branching from the condensation pipe and connected to a vacuum pump; a pressure pipe branching from the condensation branching pipe and connected to the condensation water tank; a first valve for opening and closing the condensed water pipe; a second valve for opening and closing the condensation branch pipe; a third valve for opening and closing the pressure pipe; and a fourth valve for opening and closing the connection pipe, opening the fourth valve and the third valve when the extract is moved from the extraction concentrator to the condensate tank, blocking the first valve and the second valve, and opening the second valve and the fourth valve when the extract stored in the condensate tank is moved to the extraction concentrator, thereby changing the pressure acting path of the vacuum pump.
A filter provided in the connection pipe may be included to filter foreign matters contained in the extract moving between the extraction concentrator and the condensate tank.
The extraction concentrator may include: an extraction concentration tank for accommodating an extract or an extraction target; an extraction and concentration sleeve surrounding the extraction and concentration tank for filling heat transfer oil; and an extraction and concentration heater provided between the extraction and concentration sleeve and the extraction and concentration tank, for heating the heat transfer oil.
The foamer may include: a foaming heater for heating the extract flowing from the extraction concentrator; a foaming sleeve surrounding the foaming heater, forming a flow path for the extract to pass through between the foaming sleeve and the foaming heater so as to be heated while rapidly passing through the foaming heater to realize foaming; a heat insulating material surrounding the periphery of the foaming sleeve and insulating from the outside; and a foam casing surrounding the periphery of the heat insulating material.
According to the present invention, extraction and concentration operations can be selectively performed in the extraction and concentration tank, thus minimizing the volume, thereby minimizing the installation site, and thus greatly reducing the equipment costs.
In addition, the pressure control part controls the pressure of the vacuum pump to move between the extraction concentration tank and the condensation water tank, so that the extract is not required to be exposed to the outside, thereby preventing the pollution of the extract, reducing the time required for carrying in and carrying out the extract, and preventing burn accidents caused by moving the relatively hot extract.
Further, the extract is concentrated in a form of foaming, so that the concentration of the extract can be improved, and the transparent window and the transparent connecting portion are provided, so that the state of the extract can be easily grasped from the outside.
Further, by adjusting the foaming amount according to the extract by the interval adjusting part of the foamer, the optimal foaming is performed, and thus the concentration of the extract can be improved.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in fig. 1, a compact one-stop extraction and concentration apparatus 100 according to an embodiment of the invention may include an extraction concentrator 110.
The extraction concentrator 110 may extract an extract from an extraction subject or concentrate the extract.
The extraction concentrator 110 may extract the extract in a form in which the extraction target is mixed with a solvent and then heated, or concentrate the extract in a form in which the solvent is evaporated by heating the extract.
The extraction concentrator 110 may include an extraction concentrating tank 111, an extraction concentrating cannula 117, and an extraction concentrating heater 118.
The extraction and concentration tank 111 is formed in a container shape so as to accommodate an extraction target or an extract.
The extraction and concentration tank 111 is formed in a container shape with an open upper portion, and the open upper portion can be sealed with a lid, and the extraction target can be carried into and out of the extraction and concentration tank 111 in a state where the lid is opened.
In order to confirm the state of the extracted object or extract contained in the interior, a see-through window 116 through which the interior is seen may be formed in the cover, and a lamp for illuminating the interior may be provided.
An extraction discharge port 114 for discharging the extract may be formed at a lower portion of the extraction and concentration tank 111, and a vapor discharge port 113 for discharging the evaporated solvent may be formed at an upper portion of the extraction and concentration tank 111.
A foam connection port 115 for supplying the extract to a foamer 130 to be described later may be formed on the lower side surface of the extraction and concentration tank 111, and a return port 112 for allowing the extract foamed in the foamer 130 to flow again into the extraction and concentration tank 111 may be formed on the upper side of the foam connection port 115.
The extraction and concentration sleeve 117 may surround the circumference of the extraction and concentration tank 111, and heat transfer oil may be filled between the extraction and concentration tank 111 and the extraction and concentration sleeve 117.
An extraction and concentration heater 118 is provided between the extraction and concentration sleeve 117 and the extraction and concentration tank 111, and the extraction and concentration heater 118 heats the heat transfer oil, and the heated heat transfer oil indirectly heats the extraction and concentration tank 111, so that the extract or the extraction target object stored in the extraction and concentration tank 111 can be heated.
The extraction concentrate heater 118 may be embodied as an electric heater that is heated by electricity.
In the extraction concentrator 110 having such a configuration, when the extraction target is stored in the extraction and concentration tank 111, the extraction and concentration heater 118 heats the heat transfer oil, and the heated heat transfer oil heats the extraction and concentration tank 111 and heats the extraction target to extract the extraction.
In contrast, when the extract is stored in the extraction and concentration tank 111, the extraction and concentration heater 118 heats the heat conduction oil, and the heated heat conduction oil heats the extraction and concentration tank 111 and simultaneously heats the extract and can concentrate the extract.
The extraction concentrator 110 may include stirring wings 120.
The stirring blade 120 is rotatably provided in the extraction and concentration tank 110, and can stir the extract or the extraction target object so as to uniformly heat the extract or the extraction target object stored in the extraction and concentration tank 111.
Here, when extracting an extract from the extraction target, the extraction concentrator 110 may operate only when concentrating the extract, without operating the stirring vane 120 according to the kind of the extraction target.
The stirring vane 120 may be rotated by a stirring driving motor 121, and the stirring driving motor 121 may be disposed outside the extraction and concentration tank 111 to rotate the stirring vane 120 disposed inside the extraction and concentration tank 111.
The agitation drive motor 121 may be embodied as an electric motor that rotates by electricity.
As shown in fig. 1 and 2, the compact one-stop extraction and concentration apparatus 100 according to an embodiment of the present invention may include a foamer 130.
The foamer 130 can foam the extract when concentrating the extract, thereby improving the evaporation of the solvent and shortening the concentration time.
The foamer 130 may include a foaming heater 131, a foaming sleeve 133, a heat insulating material 134, and a foaming housing 135.
The foaming heater 131 can rapidly heat the extract, and can evaporate faster than the solvent is evaporated in the extraction concentrator 110 because the foaming heater 131 directly heats the extract.
The foaming heater 131 may be embodied as an electric heater that is heated by electricity, and the foaming heater 131 may be surrounded by the heater case 132.
The foaming sleeve 133 may surround the foaming heater 131, and the foaming sleeve 133 may be spaced apart from the foaming heater 131 by a predetermined interval, and the extract may be diffused and passed through by a minute interval while being rapidly heated.
Here, since the extract has viscosity according to the concentration degree, the generated steam is not easily discharged from the extract due to the viscosity of the extract while being heated by the foaming heater 131, and is generated in the form of foam, thus representing foaming.
The foaming heater 131 may include an interval adjusting part 139.
The interval adjusting part 139 can adjust the interval t between the foaming heater 131 and the foaming sleeve 133.
At this time, the foam heater 131 may be formed in a conical shape having a narrower area toward the foam discharge port, and the inner peripheral surface of the foam sleeve 133 may be formed in a conical shape corresponding to the foam heater 131.
Further, the foam heater 131 is provided so as to be slidably movable from the foam sleeve 133 toward the foam discharge port and the foam inflow port 136, and the interval t is adjustable as the foam heater 131 approaches or separates from the foam sleeve 133.
The interval adjusting portion 139 may include a heater fixing portion 139a and a fixing and fastening member 139b.
The heater fixing portion 139a may be provided at an end of the foaming heater 131, the end of the heater fixing portion 139a may penetrate the foaming case 135 and be exposed to the outside, and a thread may be formed around the heater fixing portion 139 a.
The fixing and fastening member 139b is screwed to the heater fixing portion 139a, and the position of the foaming heater 131 in the foaming sleeve 133 is adjusted by adjusting the position of the fixing and fastening member 139b in the heater fixing portion 139a, so that the interval t between the foaming heater 131 and the foaming sleeve 133 can be adjusted.
Here, the foamability of the foamer 130 may be varied according to the kind and viscosity of the extract, and in the embodiment, the foamer heater 131 is coupled to the foamer sleeve 133 in a slidably movable manner to adjust the form of the foamer heater 131 at the position of the foamer sleeve 133, and the interval t between the foamer heater 131 and the foamer sleeve 133 is adjusted to thereby adjust the amount of foaming.
An extraction flow inlet through which the extract flows may be formed at one end of the foaming sleeve 133, and a foaming discharge port 137 through which the extract flowing into the extraction flow inlet is foamed and discharged may be formed at the other end.
In order to prevent the heat from being reduced due to heat exchange with the outside, the foaming sleeve 133 may be surrounded by the heat insulating material 134, and the heat insulating material 134 may be wrapped in the foaming case 135, thereby preventing damage of the heat insulating material 134.
The foam inflow port 136 of the foam jacket 133 is connected to the foam connection port 115 of the extraction and concentration tank 111 through the foam pipe 119, the extract of the extraction and concentration tank 111 can be supplied to the foamer 130 through the foam pipe 119, the foam discharge port 137 is connected to the return port 112 of the extraction and concentration tank 111 through the return pipe 137a, and the extract foamed in the foamer 130 is supplied to the extraction and concentration tank 111 again through the return pipe 137 a.
At this time, a foaming valve 119a may be provided in the foaming pipe 119, and the foaming pipe 119 may be opened and closed by the foaming valve 119a in order to allow the extract to move to the foaming pipe 119 or prevent the extract from moving.
In the embodiment, the foamer 130 is configured to obtain the supply of the extract through the foamer connection port, but may be configured such that the foamer valve 119a is branched from the connecting pipe 160 and the supply of the extract discharged through the extract discharge port is obtained through the connecting pipe 160 and the foamer pipe 119.
As shown in fig. 1, a compact one-stop extraction and concentration apparatus 100 according to an embodiment of the invention may include a condenser 140.

As shown in fig. 1, a compact one-stop extraction and concentration apparatus 100 according to an embodiment of the present invention may include a permeate connection 147.
The abnormal state of the extract on the path along which the extract moves can be confirmed from the outside by the permeation connection portion 147.
The transmission connection portion 147 may be provided at each portion of the structure where the extract is discharged, for example, at the condensed water discharge port 143 of the condenser 140 as in the embodiment, to confirm the condensed state of the steam or to confirm the discharged state of the condensed water.

The transparent tube may be formed of a transparent body so that the condition of the passage of the extract can be seen, flange portions may be installed at both ends of the transparent tube and coupled, the flange portions being located at portions to be connected through the connection portions 147, and an air sealing member may be provided at the flange portions for preventing the leakage of the extract.
In addition, the flange parts on both sides of the transparent tube are connected by the reinforcing strips, the transparent tube can be prevented from being damaged by the housing of the mutually connected structural product, and a plurality of reinforcing strips can be radially arranged around the transparent tube.
For example, in the case where the transparent pipe is provided in the condenser 140, the flange of the transmission connection portion 147 may be formed as follows: the flange portions formed at both ends of the transparent pipe are joined by bolting in a state where the flange formed at the condensed water discharge port 143 of the foam killer and the flange formed at the condensed water pipe 171 overlap each other.

The vacuum pump 180 is connected to the end of the condensation branch pipe 172 via a vacuum pipe 185, and can be connected to the condensate tank 150 via a pressure pipe branched from the condensation branch pipe 172.
In addition, the vacuum pump 180 may supply the extract of the extraction and concentration tank 111 to the condensate tank 150 by means of the pressure control part 170 to be described later, or may supply the extract moved to the condensate tank 150 again to the extraction and concentration tank 111 while the extraction and concentration tank 111 is vacuum-generated.
As shown in fig. 1, 3 and 4, the compact one-stop extraction and concentration apparatus 100 according to an embodiment of the present invention may include a pressure control part 170.
The pressure control part 170 may change a pressure acting path in which the suction force of the vacuum pump 180 acts so as to generate a vacuum in the extraction and concentration tank 111, or supply the extract of the extraction and concentration tank 111 to the condensate tank 150, or move the extract moved to the condensate tank 150 again to the extraction and concentration tank 111.
The pressure control portion 170 may include a condensate pipe 171, a condensate branch pipe 172, a pressure pipe, a first valve 174, a second valve 175, a third valve 176, and a fourth valve 177.
The condensate pipe 171 may be a condensate pipe 171 connecting the condensate outlet 143 and the condensate inlet 151 to supply condensate from the condenser 140 to the condensate tank 150.
The condensation branch pipe 172 may be a pipe branched from the condensation pipe 171, and the pressure pipe may be branched from the condensation branch pipe 172 again to be connected to the pressure generating port 152 of the condensation tank 150.
Further, a vacuum pump 180 may be connected to the end of the condensation branch pipe 172 via a vacuum pipe 185, and suction force of the vacuum pump 180 may be exerted by the condensation branch pipe 172.
The first valve 174 may be provided in the condensed water pipe 171 to open and close the condensed water pipe 171, and the second valve 175 may be provided in the condensation branch pipe 172 to open and close the condensation branch pipe 172.
Here, the first valve 174 is provided at a lower portion of a portion branching off the condensate pipe 171 from the condensate pipe 172, and opens and closes only the condensate pipe 171, without interfering with pressure changes in the condensate pipe 172.
The second valve 175 is provided before the pressure pipe branches from the condensation branch pipe 172, and does not interfere with the suction force acting on the pressure pipe by the vacuum pump 180 even when the second valve 175 opens and closes the condensation branch pipe 172.
The third valve 176 may be provided to open and close the pressure pipe, and when the third valve 176 blocks the pressure pipe, the suction force applied from the vacuum pump 180 to the condensate tank 150 may be blocked or opened.
The fourth valve 177 is provided in the connection pipe 160 through which the extract moves from the extraction and concentration tank 111 to the condensate tank 150, and when the fourth valve 177 is operated, the extract moves from the extraction and concentration tank 111 to the condensate tank 150, the extract is restricted from moving from the condensate tank 150 to the extraction and concentration tank 111, or the restriction of the movement can be released.
Here, the fourth valves 177 are provided on both sides of the connection pipe 160 around the filter 161, respectively, and can block the flow of the extract into the filter 161 when the extract is blocked from moving between the extraction concentrate tank 111 and the condensate tank 150.
In the pressure control unit 170 thus configured, when the extraction and concentration tank 111 is evacuated to extract or concentrate the extract, the condensed water distribution pipe is opened by the first valve 174, the pressure pipe is opened by the third valve 176, the connection pipe 160 is closed by the fourth valve 177, and the condensation branch pipe 172 is closed by the second valve 175.
In this way, when the first valve 174, the third valve 176 are opened and the fourth valve 177 and the second valve 175 are closed, while the suction force acting by the vacuum pump 180 acts on the condensate tank 150 through the pressure pipe, the condensate tank 150 provides the suction force that sucks the condensate from the condenser 140 to the condensate tank 150 through the condensate pipe 171, and at the same time, as the air of the extraction and concentration tank 111 is sucked through the condenser 140, a vacuum is generated in the extraction and concentration tank 111.
At this time, when vacuum is generated in the extraction and concentration tank 111, suction force is generated at the return port 112, so that the extract of the extraction and concentration tank 111 can be continuously circulated and concentrated in the foamer 130 and the extraction and concentration tank 111.
When the extract in the extraction and concentration tank 111 is moved to the condensate tank 150, the condensate pipe 171 is closed by the first valve 174, the condensate branch pipe 172 is closed by the second valve 175, the pressure pipe is opened by the third valve 176, and the connection pipe 160 is opened by the fourth valve 177.
In this way, when the first valve 174 and the second valve 175 are closed and the third valve 176 and the fourth valve 177 are opened, the suction force of the vacuum pump 180 acts on the condensate tank 150 through the pressure pipe, and the extract stored in the extraction and concentration tank 111 is moved to the condensate tank 150 through the connection pipe 160 by the suction force acting on the condensate tank 150.
In other words, since the suction force of the vacuum pump 180 causes the pressure of the condensate tank 150 to be lower than the pressure of the extraction and concentration tank 111, the extract of the extraction and concentration tank 111 moves to the condensate tank 150.
At this time, when the extract moves from the extraction and concentration tank 111 to the condensate tank 150, the extract passes through the filter 161, so that foreign substances contained in the extract can be filtered.
When the extract is again moved to the extraction and concentration tank 111 while the extract is flowing into the condensate tank 150, the condensate pipe 171 is closed by the first valve 174, the pressure pipe is closed by the third valve 176, the condensate branch pipe 172 is opened by the second valve 175, and the connection pipe 160 is opened by the fourth valve 177.
In this way, when the first valve 174 and the third valve 176 are closed and the second valve 175 and the fourth valve 177 are opened, the suction force of the vacuum pump 180 is supplied to the condenser 140 through the vacuum branch pipe and the condensed water pipe 171, and the condensed water pipe 171 acts on the extraction and concentration tank 111, so that the pressure of the extraction and concentration tank 111 is lower than the pressure of the condensed water tank 150, and the extract in the condensed water tank 150 can move to the extraction and concentration tank 111.
Of course, when the extract moves from the condensate tank 150 to the extraction and concentration tank 111, the extract may be supplied to the extraction and concentration tank 111 in a state in which foreign substances contained in the extract are filtered through the filter 161.
As described above, when extraction or concentration is performed only by the suction force of the vacuum pump 180, the pressure control part 170 generates vacuum in the extraction and concentration tank 111, extracts or concentrates the extract in the vacuum state, after extraction in the extraction and concentration tank 111, before concentration is performed, in order to remove the extraction target object from which the effective components are extracted, the extract is moved from the extraction and concentration tank 111 to the condensate water tank 150, so that the extract moved to the condensate water tank 150 is moved again to the extraction and concentration tank 111, and thus concentration can be performed.
Next, the operation and effects of the above-described components will be described.
The compact one-stop extraction and concentration apparatus 100 according to the embodiment of the present invention first opens the cover of the extraction and concentration tank 111 when extracting an extract from an extraction target, carries in a state where the extraction target and the solvent are mixed, and closes the cover of the extraction and concentration tank 111.
When the extraction target is carried in, the pressure control unit 170 opens the condensed water pipe 171 via the first valve 174, closes the condensation branch pipe 172 via the second valve 175, opens the pressure pipe via the third valve 176, and closes the connection pipe 160 via the fourth valve 177 (see fig. 1).
If the extraction and concentration heater 118 is operated to heat and extract the extraction target, the extraction and concentration heater 118 heats and heats the heat conduction oil, and the heat conduction oil heats the extraction target by exchanging heat with the extraction and concentration tank 111.
At this time, the stirring vane 120 may be operated as needed, and the foaming valve 119a is closed to block the flow of the extract into the foamer 130.
Further, if the vacuum pump 180 is operated, the suction force of the vacuum pump 180 acts on the condensate water tank 150 through the pressure pipe, the suction force acting on the condensate water tank 150 acts on the condenser 140 through the condensate water pipe 171, and the suction force acting on the condenser 140 is supplied to the extraction and concentration tank 111 through the steam pipe 145, so that the extract can be extracted in a vacuum atmosphere, and the steam can be moved from the extraction and concentration tank 111 to the condensate water tank 150.
Here, when the extract is extracted from the extraction target, the pressure of the steam generated in the solvent is high, so that the steam generated in the extraction and concentration tank 111 can be moved to the condensate tank 150 as needed, even if the vacuum pump 180 is not operated.
When the extraction target is heated, the extract is extracted by the solvent, the solvent evaporates, the generated steam flows into the condenser 140 through the steam pipe 145, the steam passing through the condenser 140 is condensed, and condensed water is generated, and the condensed water is stored in the condensation storage tank through the condensed water pipe 171, so that the extract is extracted.
When the extraction is completed by heating the extraction target object for a predetermined time, the extract extracted in the extraction and concentration tank 111 is supplied to the condensate tank 150 in order to remove the extraction target object from which the extract is extracted in the extraction and concentration tank 111.
At this time, the condensed water stored in the condensed water tank 150 is discharged to the outside through the drain port 165 after the drain valve 167 is opened, or is used in a place where the condensed water is required.
As shown in fig. 3, if the condensate tank 150 is emptied, the pressure control unit 170 closes the condensate pipe 171 with the first valve 174, closes the condensate branch pipe 172 with the second valve 175, opens the pressure pipe with the third valve 176, and opens the connection pipe 160 with the fourth valve 177 in a state where the drain valve 167 is blocked.
When the vacuum pump 180 is operated, the suction force of the vacuum pump 180 generates a negative pressure in the condensate tank 150 through the pressure pipe, and the pressure in the condensate tank 150 is lower than the pressure in the extraction and concentration tank 111, so that the extract stored in the extraction and concentration tank 111 moves to the condensate tank 150 through the connection pipe 160.
At this time, foreign matter contained in the extract is filtered by a filter 161 provided in the connection pipe 160, and moves toward the condensate tank 150.
When the extract moves to the condensate water tank 150, the lid of the extraction and concentration tank 111 is opened, and after the extraction target object from which the extract is extracted is removed from the extraction and concentration tank 111, the lid of the extraction and concentration tank 111 is closed for concentrating the extract.
As shown in fig. 4, in order to allow the extract stored in the condensate tank 150 to move again to the extraction and concentration tank 111, the pressure control unit 170 closes the condensate pipe 171 by the first valve 174, closes the pressure pipe by the third valve 176, opens the condensate branch pipe 172 by the second valve 175, and opens the connection pipe 160 by the fourth valve 177.
When the vacuum pump 180 is operated, suction force of the vacuum pump 180 is supplied to the condenser 140 through the condensation branch pipe 172 and the condensation pipe, and supplied to the extraction and concentration tank 111 again through the condenser 140, and at the same time, the pressure of the extraction and concentration tank 111 is lower than that of the condensation water tank 150, and the extract stored in the condensation water tank 150 moves to the extraction and concentration tank 111 through the connection pipe 160.
At this time, the extract moved from the condensate water tank 150 to the extraction and concentration tank 111 moves to the extraction and concentration tank 111 in a state in which foreign matter is removed while passing through the filter 161.
When the extract moves to the extraction and concentration tank 111, if the pressure control unit 170 opens the condensate pipe 171 via the first valve 174, opens the vacuum valve via the third valve 176, closes the condensate branch pipe 172 via the second valve 175, and closes the connection pipe 160 via the fourth valve 177 in order to generate a vacuum in the extraction and concentration tank 111 via the condensate tank 150, the suction force of the vacuum pump 180 sequentially acts on the condensate tank 150 and the condenser 140, and a vacuum is generated in the extraction and concentration tank 111 (see fig. 1).
In this state, the foaming pipe 119 is opened by the foaming valve 119a, the extraction and concentration heater 118 is operated, the extraction and concentration tank 111 is heated by the heat transfer oil, and the solvent in the extract is evaporated, and when the solvent in the extract is evaporated, the extract is stirred by the stirring blade 120 so that the solvent can be rapidly evaporated.
In addition, a part of the extract stirred by the stirring blade 120 flows into the foamer 130, and the extract foamed by the foaming heater 131 after passing through the foamer 130 flows into the extraction and concentration tank 111 again, and circulates between the extraction and concentration tank 111 and the foamer 130, whereby the concentration performance can be improved.
Then, as the extract is heated, the vapor generated while the solvent is evaporated moves to the condenser 140 and is condensed to generate condensed water, and the generated condensed water is stored in the condensed water tank 150 through the condensation pipe.
When the concentration of the extract is completed within a predetermined period of time, the recovery valve 164 is opened in a state where the operation of the vacuum pump 180 and the operation of the stirring blade 120, the foamer 130, and the like are all stopped, and the concentrated extract can be recovered through the extract recovery port 163.
Of course, the condensed water stored in the condensed water tank 150 may be recovered through the drain port 165 and used or thrown away after the drain valve 167 is opened, as needed.
Thereby, the compact one-stop extraction and concentration apparatus 100 according to the embodiment of the present invention performs extraction and concentration simultaneously in the extraction and concentration tank 111, and thus, there is no need to separately provide the extraction tank and the concentration tank, so that not only the structure is simple, but also the volume is minimized, and thus, the installation site can be minimized.
Further, since the extract is moved between the extraction and concentration tank 111 and the condensate water tank 150 by the pressure control part 170, contamination of the extract due to exposure of the extract to the outside can be prevented, complication of the extraction and concentration operation due to movement of the extract can be eliminated, moreover, burn accident of workers due to carrying of the hot extract can be prevented, and the extraction and concentration operation can be easily performed.
Further, the foamer 130 is provided to foam the extract, so that not only the concentration property can be improved, but also the foaming interval is adjusted by the interval adjusting part of the foamer 130 according to the extract, so that the foamability can be improved, and further the concentration property of the extract can be improved.
Further, the transmission connection portion 147 is provided, so that the condensed state of the condensed water can be easily grasped.
Although the embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, but includes all changes and modifications which a person having ordinary skill in the art to which the present invention pertains can easily change from the embodiments of the present invention and which are considered to be within the equivalent scope.
