[0006]Thispresentdisclosurerelates to waysofextractingand concentratingcannabinoids and terpenes from plant substrates including hemp, and particularly modifying the characteristics of thesolventtoby-passundesiredconstituentsof plants throughout the extraction process.

[0007] Extraction of industrial hemp and cannabis canbe done via many methods, usinga wide arrayof FDA-appro ed food grade solvents. The most commonly used solvents are hydrocarbons suchas hexane, pentanebutan orpropane.Lipidbasedsolvents such as canola oil, soybean oil, oliveol, flax seedol, hemp oilareals commonlyusedinhempandcannabis extractionmethods. Supereriical carbon dioxide is aso commonly used in cannabis extraction, but the expensive machinery and the post-extraction steps required topunfy a supercritical fluid extraction(SE)extractof undesired plant Ipids, makes SPE the least desirable methodforany commercialprocessor.

[0008 Several drawbacks of hydrocarbon extractionmethods hae beenrecognized. The.most prominent of these drawba is the volatilityofhydrocarbon solvents.The cost assocatedwib retrofittig a laboratory with explosion proof electronics ventilationfans, and the like, create enormousstart-upcosts. Second, purehydrocarbon solventssuchas N-butane orN-hexanc are extremely difficult to obtain and therefore are hardly ever used forcannabis exact production.

Sa,

The majority ofextracts are created with inferior, low qality butane that contains additivesand impurities.

[0009] Lipid-based extractions are safer and less hazardous tohealththan hydrocarbon-based extractions, but separating the cannabinoids or fiavonoids fromalipid emulsionreqresamore thoroughtraining in chemistry, as well as more expensivedistillationdevices,

Unsafe practicesbyT manufacturershaveresulted in explosionsand fires resulting fmuseofhydrocarbon solvents

[0086]System ofthe present disclosurecancompriseone ormore solventstoragetanks where each solvent storage tank is operably linked with a corresponding solvent storage tankvalve. In use onlyone solventstorage tank is used ata timethat is, for providing solvent to Extraction Tank(1.)Preferably,cachsol ent stor age tank holdsUsix S. gallons. Preferably, system of the preset disclosure includes foursolventstoragetanks,each with a corresponding storage tank valve. Inone aspect, allsoentstoragetanksaresituatedsideof Environment Box (.L), therebyensuring that the solvent is kept at the same temperature as thatside the environment box. For initiating delivery ofsolvent toExtraction Tank (1 1) and forcontinuingdeliveryof solvent to extraction tank, cold air intake valve (1.B) is closed, solvent flooding valve(1C) is opened and vacuumfrom vacuum pump is appliedto Extraction Tank. In a preferred embodimentvacuum applied to Extraction Tank is minus 20 inches of mercury.

[0087] Coldair intake valve (LB)is alternatively called, airlock valve orgate valve.

[0089]Branching Points Residing at Extraction Tank. Inlet and atCollection TankOutlet

[0090] Regarding flow of solution downstream ofcolection tank oudet, the relative flow at collectiontankbranching point, that is, towards theLeft branch or tothe right branch, is controlled by evacuation valve (LK) and solution return valve (I.D) Closing evacuation valve (1 K) and openingsolutionreturnvalve(D)aowsorpromotesrecirculationofsolutionfrom collectiontankbacktoextractiontank, Regarding the flowof solventand theflow ofsolution throughextractiontankinlet and into extraction tank (1.1h)therelativeflowatextractiontank branching point, that is, fromsolventtank to extraction tankinlet orfromcollectiontankto

1.7 promotes orallows transmissionof solvent from solvent tank into extraction tank. Conversely, closing solution floodingva e(1.C) and opening solution retum valve (1,) promotes recirculation of solution from collection tank into the extraction tank, for the purpose of further extracting plantmatter.

0091]Aternativeto Branching Point Structures

[0092]1nstead of using thebranching pointstructure the present disclosure provides system where extraction tank branchingpoint and extraction tank inlet isreplaced by two extraction tank inlets,where the first extraction tank inlet isdedicated toreceivingsolvent fromsolvent tank, and thesecond extractiontank inlet is dedicatedto receiving solution from collection tank. Also thepresent disclosure provides system where collectiontank branching tank and collection tank outlet is replaced by twocollection tankoutlets. where first collection tank outlet is dedicated to transmitting soluonfromcollection tank back to extraction tank (recirculating the solution), and thesecondcollection tank outlet is dedicated to transmittingsoluionfrom collectiontank to evacuation line., In exclusionary embodiments,:the presentdisclosure can exclude.a system or device that comprisesabranching point.

[0093]GenerallyRegarding.Valves

[0094]The valvesshowninthe figuresinclude 3/4 chcompressionvalves, 1/2inch compression valves, and inch sanitary butterfly valves. ForthesakeofthePIDitmaynotbe

critical to utilizeany particular design of the valves. Ina preferredembodiment, all of the valves are hand poweredThe systemismaalardrequires an operator to perform the extraction. The jacketed system built by the iventors is an automated system and has pneumatic actuators on the valves. The actuators are powered by compressed air, passed through a solenoid actuatedby a PLC.

[0095]The valves act to eitherisolate or engage flow. The flow can be of air. vacuum, orliquid. Allvalvesare quarter tur valves that either open or close. Nometering is done bythevalveson these systems. The direction of flow is detained bytheacuum beingapplied. Ifvacuum is applied to extraction vessel, opening a valve on a wet line will draw solution or ethanol into that extraction tank. Likewise, if vacuum is applied to collection vessel,a valve will start or stop the flow of liquid to that tank.

[00961Preferred Uses insideof EnvironmentBox and Outside of Environment box

[00971in embodiments, the temperature of the iernalcoldcompartmentof the environment box is displayed ona LCD screen on the HM! of the compressor, This tempe nature reading is enough for an operatorto knowthatthemachine is ready foroperation.Optionally thermocouples can be placed into thev1arious tanks and plumbing to monitor the temper atures at everystep.Asystem andmethod that employs thermocouples is not preferred. Thepresent disclosure can exclude any system and method that employs thermocouples, for exampleto monitor the temperature offludsinside fluidhiues and inside tanks or vessels.

[0098]If the overall temperature ofthe system isbelow Cwe know that itis ready for operation. The typicaltemperatresettingon the system is -60C. Having the freezer compartmentsetbelow -45C (ideal temperature for extracon) allows for coong compensaion. Someofthewet plumbingmust be externalized due to the positioning ofthe valves.As we recirculate the solution throughout the system, it tends to warm ever so slightly. We always set the freezer component toa lower temperature to compensate for that warmain.

[0099]Referringto FIG. illustrated is an inventive vessel-wet plumbing and freezer compartment assembly which has produced advantageous results. Super-cooling processes have driventheseadvantageous results with this system. Solvent Storage Tank (1,A) is operatively and communicativelylinkedtocold air takevalve(.1) via known lines tothose skilled imthe art asshown, Solvent flooding valve (LC) then rns vialines tothe solution returnvalve (1D) as shown above Extraction Tank (lT. Solution collection valve (I)is then ported through sight glass(i.F)anddowntoExtraction Tank( .and is connected to inine filter housing (J) along to evacuationvalivee (LK

[001001 IG.I showman inlet atthe topof Extraction Tank(1 11). Extractiontank inet can receive solvent fromsolvent flooding valve I C)Is open (and solution retunvalve(I.D) is closed), and it can receive-solution when solution returnvalve (ID)is open (and solvent floodingvalve(LE)isclosed).The term "sohent"or"cleansolvent" refer to solved prior to exposuretoany plant material. The term "solution"refers to any-solvent thathas been contacted with any plant material Whereany "solution isrecirculatedand usedtoextract a partially extracted plant materialths "solution' isstillcalled a "solution" and is not called a "solvent."

[00101] The following explains what controls the proportion of materalpassgthrough solventflooding valve(C) versusmaterialpassmngthrough solution retunvalve(ID). The plumbing is arrangedin sulaway that two k etl nes are connected to a igle port at the top of theld.Oncevacuum is bultin the Extraction Tank (LH). valve (C)will openthe flow of clean ethanolfrom a Solvent Storage Tank.Like isevalve (1D will engagetheflowof solution from the Collection'T ank (1).backintotheExtraction Tank for whatis called the "recirculationprocedure"The detailed arrangement of the plumbing allows a singleport to double as the floodmg andrecirculatng channel. These valves work independently ofone anotherandare never used to flood the Extracion Tankwith BOTH, clean ethanolandsolution at the same time.

[00102] The following concerns the proportion of material pass through valve (.C) vrss materialpassingthrough valve(1.D).Theeisnevera time when BOTH clean ethanol and solutionare delivered into the Extraction Tank at the same time Clean ethanol introduction and solutionrecirculaionhappenatdifferent stages of the extractionprocess- Clean solvent is introducedintothe Extraon Tankas very FIRSTstep in the extraction process Afterwards, a recirulation ofthe solution over the plantmaterial iswhat allowsmaximumextraction efficiency. After a thoroughrecitulationprocedure, another clean batch of ethanol can be introduced into the Extraction Tank to perform a fmal cleanse" or 'final wash" of the plant substrate, This "final wash" frees up any solution saturated in actives from the plant substrate,

[00103] Accordingly, the present disclosureprovides a system and method, where clean solvent, such asclean ethanol is deliveredasan "initialbatch"into an Extraction Tank as the very firststepintheextraction process, followed by one or more steps where clean solvent is not deliveredinto tbe Extraction Tank but instead there is a recirculation of solution (solution comprising substances extracted fromthe plant matter) over the plant material and whereths recirculation prove ides formaximum extraction of chemicals fromthe plant matter After the one or more steps where there isrecirculation of solutioncomprising substances extracted from the plantnmatter, in some embodiments there isnotany further extraction usingclean solvent, while

in other embodiments,thereis a final extraction final cleanse, final wash) of the plantrmatter vth a "final batch" of clean solvent.The "imtial batch" can be delivered allatonce, or as more than one consecutive smaller batches, or as two consecut esmallerbatches orasthree

consecutive smaller batches, and so on Tbe "tinal batch' can be dehvered all at once, or as more than one consecutive smaller batches, or as two consecutive smallerbatches, or as three consecutive smallerhbatches, and so on.

[00104] Introducing Plant Matter into the Extraction Tank

[00105] Extraction Tank has a lid. This lid is atached to Extration Tank via a hinge Thelid

opens,allowingank linerto be inserted into Extraction Tank, Plant material can be top fed,orit canbe placed into thetank linerprior to inserting into.Extraction Tank, The tank liner is a combination of two polyester materials: arough. 70 US mesh outer shell and afine508US mesh innerlining thatactsasthefilterThetanklinercanbecylndrical where itresemblesin generalformandfunction, a cylindrical coffeefilter thatis placed intoan extraction chamber that has acylndrical conformation. More familiar are conical coffee filters with aconical extractionchanter.andthetanklinerofthepresentdisclosure can also beconicalwhereitis placed insideachanterhvingaconicalconformation.Whatevertheoverallshape,thetank liner is porous, and optionally has both an innershelland an outer shell,

[00106In the flooding procedure, super-cooled ethanol is dawn from Solvent lank by -vacuum ioExtraction Tank at a preferred vacuum ofminus20inchesmercury.Afterpassage

of solvent (eg.,ethanolor solution through extraction tank outlet, solvent or solmion can be dispersedover plant matter outofone aperture-, out of 2, 3. 4,5, 6, 7. 8, 9, or 10 apertures, out of 10-20 apertures, out of 100-200 apertures, out of 2001000 apertures, or out of apluralityof apertures,oroutof greaterthan 10 apetures, or greater than 100 apertures, or greater than 1000 apertures. System can be configured so that the solvent or thesolution is dispensed asagushing fluid, as a dripping fluid,.as a spray, as a mist, or as any combination of the above, asany ofthe above in a continuous manner oras any of the above in an intermittentmamer.

[001071 For each extraction step, that is,witheither solvent orwith solution, available volume inExtraction Tankcan be filled to about2uabout4%about 6% about 8%about10%, about 5%, about20%,about30%,about 40%, about 50%, about 60%, about 70%, about 80%. about %,about 95%,about 00%, or to a volume that consists of range defined by any two of the above percent values.

[00108]For transfer ofsolution from Extraction Tank toCollection Tank, preferred vacuum is minus28inChes Inercmy For recirculating step. solution from Collection Tank is drawn to Extraction Tank at preferred vacuum of minus 20 inches mercury For filing Evacuation

Tank, preferred vacuum is minus 28 inches mercury. For the step of fihing Evacuation Tank, solution can be drawn from only Collection Tank ( the situation where solution from Extraction 'ank has already been transferred to Collection Tank). Alternatively, for filling Evacuation Tank, solution can be simultaneously drawn from both Extraction Tank via valve (I£E)to Collection Tank andfinallyto Evacuation Tank.

[00109] Regarding the fase bottom that is used to support tank liner. FIG. shows a false bottom in the shape of a disc. Altenatively, or in addition, false bottom can take the form of an inverted cone (poity side up, broad circular end down. False bottom has apertures or perforatons that arc preferably 2 milmetersin diameter. The liner, which contains plant matter, can reside directlyon topof disc-shaped false bottom or directly on top ofinvertedconefalse bottom.

[00124] Steps inMethods of thePresentDisclosure

[00125] FIG. 4 alsoshows the plumbing and how thepor arts systems were improved, while FIG.5 shove s optimized systems for select moietes, as discussed above. FIG. 4 shows control valves 1 2, 3.4and 6with gate valve 4, vacuum gauge ID. In FIG, 5, the vacuum pump is attachedviaplumbigtothreevesselsinthe system, Extraction vessel, collection vessel, andan external evacuation vessel FIG 5. They're referred to as Material Pot (extraction vessel), Collection Pot (collection vessel), and Vacuum Vessel(evacuation vessel). Bach one of these vessels has a vacuum port that connects plumbing anda valve to the vacuum pump. The evacuation vessel is external and allows us to evacuate the solution from thesystem via vacuum assist. The evacuation vessel is connected to valve K from FIG. I

[00126] In FIG. 4, the horizontal fluid line shown atthe very top connects valve:I tovalve2, and servesas thereirculation pipeaswellastheevacuationpipe. Thisline transmits from the collectionvessel to the extraction vessel This line also serves as the evacuation line, whenwsteps are taken for evacuation. In FIG. 1, that pipetnestarts below the Collection Tankand splits to theleftandright The branch to theleft leads to valve I.D, and the branch to the rightleads to valve E.

(00127] InFG.4,thevacuumisalwaysappliedtotheairspaceofthe tanks (thevacuum ine does NOT connect into thewetplumbing.))The inventor's believe that at thetemperaturesat which the system is operated, the ethanol actually has negative vapor pressure and isabsorbing moisture from atmosphere.Theientorsdonottypically sense any ethanol vapor being evacuated from.the vacuum pump.

[00128] Ju FIG. 5, the Mateaial Pot does the samething as Extraction Vessel shown in FIG. 4. In FIG. 5, the Collection Pot does tie same thing as Collection Vessel that is shown in FIG. 4.

[00129] Vacuum Gauge and Advantage of Vacuum Assist

00130] The abbreviation "VG" as shown in FIG. 4 and FIG. 5means."vacuumgaugeBoth the Extraction Vessel and the CollectionVesselhaveavacuumgaugetodeterminehowmuch vacuum is in either tank at any given time. The vacuum level is a visual cue to theoperator,as to whentoopenavalve and when to close the valve. A advantage of usingvacuum for driving flow of solvent and of solutions through fuid lines and into and out of various tanks, is that vacuumassistdoes not create flammable aerosols.

[00149] Steps inMethods ofthePresent Disclosure (further descriptions)

[001501 FIG. shows the use of an extraction apparatusdesigned toperform extraction in accordance with the present invention.

[00151] Steps 1and 2 of theprocess represent a pre-processstep inwhich both the solvent and plant substrate are chilled to a desired temperature between -I degrees C and -50 degrees C, preferably to a temperature between -30degrees C and -50degreesC,ideallytoatemperature range between -40 degrees C and -45 degreesC. In thisembodiment of theaforementioned step,

the useof an ulta-ow freezer is adequate.I another embodiment ofStep I the solvent can be chilled via jacketed Extraction Tank (1.H) and cryo chillerassembly. This steprequiresalong period of time toachieve the desire temperature of the solvent, and therefore it is recommended that anultra-low storage freezeris acquired to prevent bottle necking at Step 1 or2.

[00152] Step 3 includes ajacketed Extraction Tank such as a chemical reactor In another embodimentofStep 3of ajacketed Collection Tank, such as a chemical reactor can be added to theapparatus.Iuthis embodiment, thejacketed Collection Tank allows tocreate are-circulating system tomove chilled solventfrom Collection, akbackintothe Extraction Tank. Re circulating chilled sovent over the plant substrate.has been recognized to produce a richer concentration of desired essentialoils, cannabinoids, flavonoids and terpenes inthe solution concentrate Inathird embodiment of Step 3 ajacketedholding vessel, such as achemical reactor, can be added to the apparatus assembly. Inthisembodimenttheholdingvesselallows for mechanicalfeedingof the solvent into the Extraction Tat, eliminating streimous manual labor of pouring solvenintotheExtractionTankbyhandIn all embodiments of Step 3the vesselsmustbeabletomaintain adesired temperature range of -40 degrees C to-45 degrees C.

I00153] Step 4a includes a process in which the chilledsolvent is transferred intothe Collection Tank(l.1. Step iof FIG. 4 allows for the solvent to be chilled within the vessel via circulation of cooling solution within the jacket wallsof the vessel. Step 4b includes process in which the plantsubstrate is placed inside theExtraction Tank ofthe apparatus In one embodiment the plant substratecan be loosely placed insidetheExtractionTank.Inanother embodiment the Extraction Tankislined with micronmesh screen bag prior to the introduction of the plant substrate into thevessel Lining the ExtractionTank with micron screen bag allowsfor immediate separation of solution concentrate and plant substrate during the solution concentrate evacuation of Steps 6a and6b. This method also allows for the quick vauation of plant substratefromtheExtractionTankbysimply removing thebag filled with plant substrate out of thevessel

[00154] Step5allows for contact tie between chilled solvent and chilled plant substrate. The contact periodshould be carried out at the ideal temperature range between -40 degrees Cand degrees -45C. Contact time can be between minute and 60minutespreferably between minutesand 10minutes, ideally between minute and 5.minutes.

[00155] Step includes aprocess ofinihneseparationofsolutionconcentrateandplant substrateAnembodiment Step4bof FIG.4 provides that plant substrate isplaced within a micron mesh bag pnor to its introduction-into theExtraction Tank This embodiment of Step 4b hasbeenrecognizedasthemostsimpleandcosteffective way of inner filtration. In another embodiment ofStep 7,asolid stainless steel micron screen can be introduced via a false bottom insidetheExtraction Tank, Inthis embodiment of Step 7,the plant substrate sits atopthe false bottomstainless micron mesh as thesolution concentrate isdrawnthrough it and out of the Extraction Tank. In a third embodiment ofStep 7 afilter holder canbe introduced inline between the Extraction Tank and Collection Tank intothe apparatus assembly.

0156] Step 8 of FIG. 4 includes the collection of solution concentrate from the Extraction Tank into a jacketed.Collection Tank referenced inembodiments of Step 3.

[00157] Step includes a process ofrecirculation ofsolution concentrate back over the plart substraeto create aricherconcentration ofdesired constituents of the phuitsubstrate Recirculation can be performed viamechanical solvent pump, positive pressure in Collection Tank, or negative.pressure within Extraction Tank. The preferred method for recirculation is by manipulating pressure within the vessels. Moving the solution concentrate from vessel to vessel vianegative pressure has provento be the most cost effective as vacuum pumps have a long life expectacy and do notrequire muchmaintenance.Pressurizing the vessels to move the solution concentrate has also been recognized as effective, but the added expense of food grade nitrogen or expensive moisture traps and filters for ambient air compressors have proven to be burdensome. Mechanical solvent pumps have been recognized as an effective means ofmoving the solvent andsolution concentrate, butthecostsassociatedith suchdevices woulddeter

smalloperatorsf-om applying this method.

[001581 Step 9t cludesa methodforevacuatingthesolutionconcentratefromthe Collection Tank Asreferenced in Step 9anoving the solvent or solution concentrate can be achieved via positive or negativepressure within the vessels ofthe apparatus.For evacuation, it is been discovered that a simple drain at the bottom vessel is suitabIe for evacuation of thesolution concentrate.Positive pressure can beapplied tothe Collection Tank to expedite theevacuation process.

[00159] Step 10providesa method for separatingthe concentrate from Solvent viarotary evaporator simple distillation oratospheric evaporation. The preferred method is rotary evaporator asthismethod allowsforrecoveryofthesolventinits entirety. The recovered solvent is put baciInto circulation for future extraction, making this methodoneofthemostcost effective for any processor.

[001611 In this embodiment, thesystem is sealed frlgerthroughput, with vessels capable of holding up to 20 pounds(Ibs) ofplantmaterialaidup to 40 gallons of solvent.

[001621 In thisembodiment of the present invention, an ultra-low circulating chiler is attached to thejackets on the reactor vessels,

[0165] In this embodiment theCollectionTankactsasthesolventstorage vessels prior to commencing the extraction. During extraction procedure, the Collection Tank acts as an intermittent solution storage vesselduringrecirculaonprocedure&

[00166] Plant material isloadedinto ameshscreenbag and placedinside the.Extraction Tank Allowing timefor the material to chill to a desired temperature of below -35 degrees C, preferablybelow -45 degrees C, ideally below -55 degrees C.

[00167] Solvent is placed inside the collection and allowedtime to chill to thenecessary temperature range between -45 and-75degreesC.Ithas been discovered that the ideal extraction temperatureisintherangeof-45Cand-50degreesCsystei parameters are always setto a lowertemperaturetocompensatefortheheatingof solvent and material during fluid transfers. The solvent will typically gain5 degrees during each fluid transfer. A typical recirculaion procedurerequiresthesolvent to be moved upto5 times from Extraction Tank to Collection Tank and back.This raises theoverall temperature of the solvent in the system byupto25 degrees C.

[00168] Cryo Chiller Versus Other CoolingMachines

[00169]Acryo chiller is as effective device to chill the extraction apparatus bycirculating a cooling solution throughout thejackets ofthe vessel included in the apparatus assembly. Not all ofoursystems employ cryochiler. Non-cryo chiller embodimes employ refrigeration compressors chill aninsulated box that houses all of the crucialcomponents. Drawings for the chiller poweredsystem can be submitted. In exclusionaryembodimensthe present disclosure canexcludeanysystem,method,orcompositionsprepared by the system, where a crychiller was used.

[00170] Advantages of Reirculation

[00171] The term"recirculationr" refers to recirculating a"solution" and does not refer to any recirculatingofany"solvent. Theten'solution" refers to asolvent that contains chemicals extracted from plantimaterial. Plant matter is contacted by super-cooled ethanol, that is enough for an extraction of the essentials totake place. By recircuation, the system achieves a super saturation of the solution, and ultimately the system and method flushestheremainingdesired chenmicalsactives") from theplant matterby a final cleansing rinsewith clean solvent.

[00172] In anotherembodimentofthepresent invention, a solvent transfer pump can be employed to move solvent fromone vessel to the next, or torecirculate the solution within the Extraction Tank Mechanical pupshave shown to be efficient buttend to generate more heat thedesired, therefore heating the solvent duringfluid transfers or recirculation, The method does notpredictably work as desired in a lipids andchlorophyll become available to the solvent at temperatures above~40degrees C.

[00173] Need to Maintain Low Temperature During Filtering

[00174] The inventors experimentedwithseveralmethods of extracting, draining and firing. Using Buchner funnel to filter thesolution of fine dust was one of the wayswe tried doing so. It became clear that even the slightest amount ofplant dust inthesolution would"bleedgreen" orallowfortheextraction of chlorophyllata roomtemperature fiction. Indesigning our machineandsystem,weplaced the filter housing and filterINSIDE the freezer compartment. This prevents the fine plant dust fromreachingatemperature at which it can start seeping chlorophyll into the extract rich sohition during filtration.

[001751 Filters and FilterAssemblies

[00170]i n a preferred embodiment filtering ofparticulates and dust released from plant matter during extraction process is accomplished by a "tank liner" thatis inserted into the extraction vesseL in this embodiment, no fiter is needed in the fluid line (pipeline that connects extraction tank outlet to collection tank inlet. However, a filter canbe used in the fluid line that is in addition to "tankiner" and a filter canbe used in fluidline where there the system does not inlude any "tankliacr."

[00184) Coordinating Vacuum Pumping-with AirLocks

[00185]The direction ofthe flowisdeterminedbywhichdirectionvacuum is being applied from,Preferably,theexit valve( ) is operable linkedtoandincommunication with an external Evacuation Tank(.R), Preferably, this operable linking is via polytetafluoroethylene (PFE) tubing or silicon tubing. The Evacuation Tank (1.j is also operably linked to avacuum pump that createsa negative pressure, Once vacuum developsin the evacuationtank,exitvalve

[00186] Operating the Cold Air intake Valve that is Located in-Line with Cold Air IntakeTube

[00187] Cold air intake valve (LB) is alternatively calleairlock valveor ate valve. Cold air Intake valveisoperably liked with upper-end terminus of cold air intaketube. Cold air intake tube has upper-endtermimusandlow er-endterminus. The cold air intake tube reaches to the very bottom of the EnvironentBoxultra-lowtemperaturefreezerchest) (iLthathousesall of the components pictured in FIG.1. Thetemperature insidethe Environmen'tBox (IL)is typically between -60C and -75C. The cold air imtakevalve (1B) acts as an airlock, When cold air intakevalve is in the OPEN position, valve (C)acts asavent forExtractionTank (1I), When thecold airitakevalve is CLOSED, valve(C)drawssolventfroma Solvent Storage Tank (A)Inside the Environment Box..This solvent is preferably ethanol.

[001881 Sincewe use vacuum forliquid transferswithin the system. each tank needs a vent to prevent an equilibrium of vacuumwhich ultimately stops the flow. The Extraction Tank needs to suck cold air during this process toprevent theplant material from armingtoo much. The ColleetonTank (L.I) sucks ambient atmosphere (viavalve LG) because it never holds plant material, and the little bit ofwarm air that enters thattank during recirulation procedures does not influence the extraction process any way If the coldair take was not there, we would equalize vacuum in both tanks during thecollection of solution from the plant material. Ifthe extraction tank was ventedtoatmosphere,the drawofwari room temperature air, into the Extraction Tank wouldraise the overall temperature inside the Extraction Tank (1III), .Where the presentsystem is used for extracting plant mateal thatcontains chlorophyll, the raisingof overall temperatureinside of Extraction Tank (11) leadstoarelease of chlorophyll into the solution. This release of chlorophyll into the solutionisNOT desirable and thus it is the case that raising ofthe overall temperaturemust be avoided

[00204] Supercritical fluids andsubcriticalfluids

[00205] The following provides non-limiting guidance on solvents that aeencompassed by the

present disclosure. Supercritical fluidsare substances at pressures and temperatures above their critical values. Their solvent power is the highest for non-polar or slightly polarcomponents and decreases with increasing molecular weight. They can easily be removed from the solutes by mere expansionto ambient pressure. Carbondioxide (CO2) is particularlyadvantageousfor

processing food materials, Supercricalfuids are used for batch extractions of solids, for multi stage counter-current separation(fractionation)ofliquids, and fbr adsorptive and chromaographicseparations (Brunner G (2005) Superritical fluids:tecnology and application to food processing.J FoodEng, 67:21-33). As stated by Poliakoff "Supercritical fluids are highly compressed gases which combine properties of gases and liquids inan intriguing manner. Fluids such as supercritical xenon,.ethane and carbon dioxide offera range of unusual chemical possibilities in both synthetic and analytical chemistry." Below critical parameters, two distinct phases exist Iiquid and vapor). Astemperaturerises, the liquid expands andthetwo phases become less distinct, and what is formed is anewsupercritcal phase (Simon Poliakoff (Jan.2001)Anitroduction to Supercritical Fluids.,Univ. of NottinghamtjAccording to US2009/0053382 of Kawamura, "Once a specific temperature and pressure (criticalpomt)are exceeded, the boundary betxveengas and liquid will dissipate. leaving a region where the fluid is susined i a statein which both phases are blended together. Such a fluid is called a supereritical fluid. Supereritical fluids havehigh density and have properties somewhere between agas andaiquid. Subcritical fluids aref uids inestate in whichthepressure and temperature are below the critical point.:Examples of themethod forsupplying the higb-temperature, high pressurefluid includebatch systems, in which the fluid is supplied to a pssure vessel, and a set processingtimeismaintained whilethe temperature andpressure increased.Alternatively, in a continuous system, the fluid is Made to flow for a set period of time in apressure vessel from a fluid-supplypathway toa fluid-dischargepathway providedto thepressure vesselsothatthe fuidwillbe discharged from the fluid-discharge pathwayat anexit pressure that is higher than atmospheric pressure."
