Description

RECEIVED at IPONZ on 26 November 2010 *10059740459* The invention relates to ethanol production and spirits purification in general and more particularly to a system combining the apparatus and method of complete technological process for alcoholic beverage manufacturing. Suitable for small and medium scale ethanol spirit and vodka related products manufacturing.

Statement While technology in industrial alcohol production fields are progressing and move forward the small and medium scale distilleries are yet rely on old fashion still pot systems.

Those systems are first very costly to manufacture.

Second too complex and heavy, third simply inefficient, produce low quality spirit (result is - complex and expensive system of filtration and spirit treatment must be used) that are not able to achieve high percentage of alcohol by volume, constant decrease of spirit percentage during distillation (result is - spirit left in a pot after distillation), lack of precise spirits (fraction) separation (result is - most of impurities are still presented in the final product that affects the taste quality).

Fourth, a lot of time wasted to preheat ferment to the point of evaporation because of big quantities of ferment to redistill at once.

Fifth, a ferment is contains different acids esters and other impurities and while boiled for many hours during distillation the new types of chemicals are formed that getting distilled with ethanol along.

To solve listed above problems the system of complex of apparatus for spirit production and further purification was designed and embodied.

Detailed description.

The following is detailed description of the construction way of the complex of apparatus for spirit production and further purification.

RECEIVED at IPONZ on 26 November 2010 Instant continuous distillation machine.

The range of continuous distillation machines was build where is the only difference is actual size and arrangement of distillation columns within one common frame. The experiments showed that different columns (different size, power consumption) can be installed within one frame, use separate power supply and share common low pressure pump, ferment supply and water distribution system, though any column within arrangement can be switched on or off independently and will not affect the ability of other columns within system to produce spirit. Though size of columns could be different they all share the same design, thus the following is detailed description of continuous distillation machine, to make it easier to understand the way of construction the small single column machine will be described below.

To build the continuous distillation machine the main column should be constructed first. The column of present continuous distillation machine is made out of stainless still 50mm diameter tube, the total length of tube is 1300mm, the tube must be divided on three sections: first section is 2cm long (will be used for low section of column and form collection chamber) second section is 20cm long (Will be used for low section of column and form Ferment/waste heat exchanger. Third section is 108cm long (will form the main column).

The construction of column is started from low sections, thus heat exchanger is build first, to build heat exchanger one will need three round (50cm diameter) pieces of flat stainless steel 1.2 mm thick, five small diameter stainless still tubes of exact length as second section of column (20cm), 2 cm section of 50mm tube, two small pieces approx 4cm long of stainless steel tube to make inlet and outlet connections, in two flat round pieces must be drilled five holes each, diameter of the holes are equal to external diameter of small stainless steel tubes.

Two flat pieces with drilled holes are get welded to 20cm section of tube, two holes with diameters are equal to diameter of small inlet outlet tubes are drilled on sides of 20 cm section next to flat pieces welded. Small inlet and outlet tubes are getting welded into holes that are drilled in 20cm section. 6 RECEIVED at IPONZ on 26 November 2010 Five small diameter tubes are getting inserted into holes in flat pieces of metal that are welded to 20 cm section and also welded around of edge of each tube to form tubular heat exchanger with tubes are welded into it and inlet and outlet tubes are welded in. Small 2cm section is getting welded to the selected to be the low end of heat exchanger. The third round piece of flat metal is drilled in the centre and welded to the small 2cm section that already welded to the low end of heat exchanger.

To the drilled hole of flat piece that welded to the bottom of heat exchanger waste/water heat exchanger must be welded, to build this heat exchanger one will need thin walled stainless steel tube of approx 13mm diameter, 30cm long with one end bended at approx 90 degrees, the length of stainless still tube of 30mm diameter and 20cm long, two round pieces of flat metal with one hole in each piece to insert 13mm dia. thin walled tube, two small pieces of small diameter stainless steel tubes to form water inlet and outlet. Two flat drilled pieces are welded to30mm diameter 20 cm long piece of tube, two holes are drilled one on each end of this 20cm section to accommodate inlet and outlet tubes. Inlet and outlet tubes are welded into places, 30 cm thin walled tube is inserted into holes drilled in two flat pieces that already welded and get welded around joints between the inserted tube and edges of holes the tube inserted to. The complete waste water heat exchanger is attached by welding to previously build low section heat exchanger ( 90 degrees bended end of heat exchanger is welded to central hole of low section heat exchanger. The ready assembled low end heat exchangers are must be welded to main distillation column, to build man column one must take third 108mm section of column, determine the low end (round tube whatever end can be chosen to be upper or low end) measure approx 30cm from determined low end and drill the hole of 20 mm diameter, then 20mm diameter approx 25cm long stainless still tube is welded to form "T" shape with blind ends and many small diameter holes are drilled all around the tube to form steam distribution passages. The ready assembled "J" shape tube is inserted into the main section of distillation column with middle welded end sticking out of 20mm hole (welded around), previously drilled in the section of distillation column and inserted tube is positioned in the centre of section of distillation 7 RECEIVED at IPONZ on 26 November 2010 column. After the steam distribution tube is in place the low end of distillation column is getting welded to upper end of waste/ferment heat exchanger.

After the assembly of heat exchangers and section of distillation column are welded together the empty space of inside of distillation column is filled with spiral stainless steel coils almost up to the top, leaving approx 10cm of empty space before the top of the column. The section of distillation column is getting drilled just above the spiral filling, small metal rods are inserted through the holes drilled to form sort of mesh inside the column above the spiral filling to secure the spiral filling in place, the rods inserted are welded around the holes and section of distillation column is treated on places of welding spots to maintain the uniformity of column surface where the welding took place.

Next step is fabrication of blind type dephlegmator to build the dephlegmator one will need the piece of stainless steel tube of 25cm long and 100mm diameter, two stainless steel flat round pieces of 100mm diameter, approximately 2 meters of thin walled small diameter stainless steel tube formed into coil where one end of the coil is directed into the inner space of formed coil will be pointed into unfilled top end of distillation column. Two small pieces 4cm long of stainless still tube of approx 14mm diameter to form vapor and liquid outlets on dephlegmator.

To build dephlegmator - one flat round piece of metal is drilled in the centre to make opening of 50mm diameter for distillation column insert, ad two small diameter holes for the coil inlet and liquid spirit outlet. The drilled flat piece is getting welded to the section of 25cm long 100mm diameter stainless steel tube this end of dephlegmator is the bottom end, on the top end the hole of approx 14 mm diameter is drilled to accommodate vapor outlet 4cm long tube. The 4cm tube is welded to the hole on top end of dephlegmator, and then dephlegmator is placed onto the top end of distillation column allowing 10cm of distillation column to get into the dephlegmator inner space. Then the dephlegmator getting attached via welding to distillation column in the place of hole edges the distillation column is inserted to. After the dephlegmator body is welded to distillation column the second small 4cm long and 14mm diameter piece of tube is getting welded to the bottom end of dephlegmator into the previously drilled hole. The coil is inserted into 8 RECEIVED at IPONZ on 26 November 2010 dephlegmator inner space allowing outer end of coil to get outside the dephlegmator through the previously drilled hole. The coil should occupy the space between the outer walls of inserted into the dephlegmator distillation column and inner walls of dephlegmator itself, plus the end of coil that pointed into the inner coil space must be directed and placed in the centre of inserted distillation column allowing the liquid to be directed into the column space. After the coil is installed the top end of dephlegmator is getting closed by remaining round flat piece of metal and flat piece of metal is welded around to the body of dephlegmator sealing the top end of continuous distillation column.

Next Step is fabrication of spirit/ferment cooler/heat exchanger; further spirit/ferment heat exchanger.

To build the spirit/ferment heat exchanger one will need section of 30 cm long 100 mm diameter Stainless steel tube, 2cm long section of the same diameter tube, 2.5m long 13mm diameter thin walled stainless steel tube formed into coil, three flat round metal pieces of 100mm diameter, two small 4cm long 14mm diameter stainless steel tubes to make spirit/vapor inlet, two small 4cm long 12mm diameter stainless steel tubes to make ferment inlet outlet. Assembly of the spirit/ferment heat exchanger: drill two holes in one of the flat pieces of metal: one hole is for coil end and another is for 4cm long 12mm diameter section of tube. After holes are drilled the flat piece is welded onto section of 30cm long 100mm diameter tube closing the bottom end of spirit/ferment heat exchanger. Another 12mmdiameter hole is getting drilled on the top end side of spirit/ferment heat exchanger for ferment outlet tube to be welded on. Small piece of tube 12mm diameter and 4cm long is welded on the top end side of spirit/ferment heat exchanger, forming ferment outlet. Then coil is inserted into the 100mm diameter tube allowing one end of coil get through the hole drilled in the welded flat piece of metal, this end of the coil is welded around the edges of the hole where is end of coil is inserted to. After coil is welded into place another small piece of tube 12mm diameter and 4cm long is welded into the hole previously drilled in the round flat piece of metal (that already welded onto the body of spirit/ferment heat exchanger) Forming ferment inlet. When bottom part of spirit/ferment heat exchanger is assembled then another flat piece is drilled to accommodate the upper end of 9 RECEIVED at IPONZ on 26 November 2010 the coil that inserted into the body of spirit/ferment heat exchanger, free end of the coil is inserted through the hole in the flat piece and welded around so the edges of round metal piece and edges of the upper end of heat exchanger are getting welded together forming closed cylinder with coil inside and free ends of coil are sticking out of upper and bottom flat ends of the spirit/ferment heat exchanger. The end of cylinder where one of the ends of the coil and ferment inlet is welded is the bottom end of spirit/ferment heat exchanger and will be pointed downwards.

The free end of the coil that sticking out of upper end of heat exchanger must be cut down and must look like a hole on the flat surface, forming inlet into the coils internal space. After the end of coil is cut down, the 2cm long section of the 100mm diameter tube is welded onto the upper end of the spirit/ferment heat exchanger, then the third flat round piece of metal is drilled in two places, diameters of holes are 14mm to accommodate two small sections of stainless steel tube of 4cm long. When are holes are ready the flat round metal piece is welded onto the 2cm section (previously welded onto body of the spirit/ferment heat exchanger) forming enclosed chamber with two holes on top (14mm) where are two remaining small sections of stainless steel tube of 14 mm diameter and 4cm long are getting welded (forming vapor/spirit inlet).

Next step is construction of instant steam generator (steam generator is connected to distillation column via "t" shape steam distribution pipe) The steam generators that were used for the variety of apparatus for spirit production and further purification are share the same construction and principles though differ in size accordingly to the size and power consumption of distillation machines the steam generators were used for. This type of steam generators is very simple and gives almost instant steam on demand. The following is the description of construction of the steam generator that is used for the present embodiment of instant continuous distillation machine. For the body of the steam generator is used 50mm diameter and 50cm long stainless steel tube where the top end of tube welded close and the bottom end is equipped with stainless steel threaded nut for a heating element to be screwed on. Upper side of steam generator is drilled through and 20mm diameter 3cm long tube is welded into this hole plus 30mm diameter 5cm long RECEIVED at IPONZ on 26 November 2010 tube is welded onto 3cm long tube via lower side end to form steam receiver. The top of 5cm tube is welded close and at the top side there is threaded connector to connect the steam generator to distillation column. The bottom end of steam receiver is connected with the lower side of steam generator body via the small diameter stainless steel tube to allow the water condensed in steam receiver to flow back into the body of steam generator. The water supply connection is made of different diameter stainless steel tubes to form water lock and prevent water to flow backwards under the steam pressure (all construction is made so that there is no possibility of pressure build up, all distillation machines that this specification is relates to including spirit purifier are constructed so that all distillers have the bypass that connected to the atmosphere to maintain atmospheric pressure during distillation inside of distillation machines). The level of water in steam generator and speed of water supply is maintained by the water distribution vessel that connected to centralized water supply via floating ball valve system and through water/ waste heat exchanger, on the other end connected to water lock of steam generator - wile water is evaporated in steam generator the water level is dropping equally in the steam generator body and the water distribution vessel, floating ball moves downwards and opening the water valve, supplying the water into system constantly while system is switched on when distiller is switched off the level of water raising and floating ball forcing the water valve to close water supply.

Description of interconnections, exploitation and principal of work of instant continuous distillation machine.

Interconnections : As schematically shown on fig 1. the internal space of spirit/ferment heat exchanger that surrounds the coil is connected at the bottom through the ball valve and low pressure pump to the vessel that filled up with ferment, the open end of the coil is should be connected with short piece of flexible pipe and used for spirit connection. Two inlets on top of spirit/ferment heat exchanger are connected to the outlets on top and bottom sides of dephlegmator for spirit and vapor collection. The side tube that located on top side of spirit/ferment heat exchanger and is opening to the internal space of spirit/ferment heat exchanger that surrounds the coil is connected to low tube that located on low side of waste/ferment heat li RECEIVED at IPONZ on 26 November 2010 exchanger (low section of distillation column), the upper tube that located on waste/ferment heat exchanger is connected to free end of the dephlegmator coil.

Principal of work of instant continuous distillation machine.

Ferment at low spirit percentage is constantly pumped from any vessel through the low pressure pump and manually controlled ball valve into spirit/ferment heat exchanger. At the same time water from any water supply runs through waste/water heat exchanger (taking the heat from the waste running through the waste release tube inside of waste water heat exchanger) and floating ball controlled valve into the water distribution vessel, from water distribution vessel water runs into the steam generator reconverted into the steam state and through the "T" shaped steam distribution tube is distributed equally within the column and conduct the heat to spiral coils. Because the system works at atmospheric pressure the temperature inside the column is slightly below the 100 degrees Celsius that condition is makes spirit evaporating and move upwards and water condensing and move downwards the column releasing the heat at low section of distillation column in both waste/ferment and waste/water heat exchangers.

The ferment is moves upwards inside the spirit/ferment heat exchanger collecting heat from the coil where hot vapors and liquid spirit are condensing and moving downwards under the gravity forces. At the top of heat exchanger the ferment is almost as hot as vapors that run through the coil in spirit ferment heat exchanger, leaving the spirit/ferment heat exchanger hot ferment runs through the tube downwards into low section of distillation column filling up the waste/ferment heat exchanger where through the set of metal tubes condensed and hot waste is running out of column releasing the heat into ferment that occupies internal space of waste/ferment heat exchanger around of the set of metal tubes. Because the ferment is isotropic liquid that shares properties of all liquids containing in mixture (spirits, esters water) the temperature of boiling point of ferment is lower than temperature of hot waste (that no longer contains spirit) that runs through waste water heat exchanger, thus ferment running through the waste/ferment heat exchanger leaving the heat exchanger in a boiling state, despite of being ready 12 RECEIVED at IPONZon 26 November 2010 for evaporation the ferment is send further through the tube into the coil that occupies the space inside the dephlegmator Fig. 1 (top section of schematic), the dephlegmator internal space is already filled up, with hot vapors of spirits an partially water, transferring further heating to the ferment inside the column. The coil is slightly colder than surrounding vapor and some vapor is getting condensed around the coil and outer walls of dephlegmator, because body are in constant contact with surrounding atmosphere (though all length of column excluding dephlegmator is heat insulated), plus as believed the dephlegmator's internal space and diameter is bigger than diameter of the distillation column so the vapors are subjected to instant pressure drop while entering dephlegmator that causes partial condensation due to cooling effect, thus liquefied spirit is escaping the dephlegmator through the tube at the bottom of dephlegmator and vapors are running through the tube at the top of dephlegmator. The outlet tubes are share the common collection chamber at the top of spirit/ferment heat exchanger where they are run through the coil finally condensing, plus relatively big diameters of tubes are used for outlet of dephlegmator and for inlet and cooling coil of spirit/ferment heat exchanger to maximize pressure equalization between internal space of dephlegmator and atmosphere. The ferment is boiling and running through relatively small diameter tube of the dephlegmator coil directed into relatively big diameter tube of distillation column that filled with metal spiral filling that are as hot as water steam penetrating spaces between the metal spiral fillings. Once the boiling ferment is subjected to the internal space of distillation column the instant evaporation occurs forcing the spirits to evaporate and water vapors to condense. The water and spirits vapors that are not evaporated are run downwards the column around and between the spaces of spiral fillings Interacting with water steam where heat/mass exchange process is taking place - water steam is hot and forcing spirit to evaporate and waste that contains spirit is colder than water steam forcing the water to condense, (the filling design - flat metal spirals creates big surface area inside the column, never get clogged, does not create internal resistance to vapor liquid flows) thus due to numerous repeating of evaporation and condensation inside the distillation column the only lightest spirit vapor is reaching the dephlegmator internal space where partially condensed spirit is directed out 13 RECEIVED at IPONZ on 26 November 2010 of column trough the spirit/ferment heat exchanger into any spirit collection vessel.

This machine can comfortably work with fermented liquids without those liquids are being filtered prior distillation those liquids are: made of mixture of sugar water and yeast, dextrose (glucose, fructose) water and yeast, maltose water and yeast, molasses water and yeast, sugary syrups as corn or sugar cane syrups water and yeast, in case of usage of solid grain or fruit materials the fermented liquid must be separated from any solids though cloudiness in ferment should not affect the work of continuous distillation machine. Exploitation of instant continuous distillation machine.

The exploitation of continuous distillation machine is simple and almost does not required any previous experience of work with distillation equipment. To start the distillation one should check the availability of water supply.

Prior to start the water distribution vessel is filled up to the level required with hot water (the water supply is the cold one, water will be heated automatically once the power is switched on) once the water distribution vessel is filled up the water supply should be opened. Second step is to open the ferment supply control valve that locates on the bottom side of spirit/ferment heat exchanger, after that the valve on ferment storage vessel is opened up and low pressure pump is switched on. The connection between waste/ferment heat exchanger and dephlegmator coil is made out of clear plastic and allows to observe the ferment movement, so after the pump is on allow the ferment to fill all heat exchangers and once the ferment is reaches the dephlegmator the ferment control valve on the spirit/ferment heat exchanger must be closed, but low pressure pump is remaining switched on until the end of distillation, so the valve on ferment storage vessel is remaining open until the end of distillation. Once the column's heat exchanges are filled with ferment the power supply to steam generator must be switched on, in few minutes time the distillation column will reach the working temperature, a liquid will start to run out of spirit/ferment heat exchanger plus spirit/ferment heat exchanger will start to gain temperature and becoming hot from the upper part down to lower part. One should not allow the spirit/ferment heat exchanger to become completely hot thus when the 14 RECEIVED at IPONZ on 26 November 2010 spirit/ferment heat exchanger's upper halve becomes hot this is time to slowly open the ferment controlling valve on lower part of spirit/ferment heat exchanger . the ferment controlling valve is opened in few steps slowly allowing the right amount of ferment to entry distillation machine, the ferment controlling valve should remain in the position when spirit/ferment heat exchanger is equally hot at the top halve and cold at the bottom halve. Correctly adjusted continuous distillation column will not require any further adjustment during all distillation. If the continuous distillation column becomes cold due to too much of ferment entering the column, one should close the ferment controlling valve without switching off power or water, wait until the distillation column and spirit/water heat exchanger are gain they temperature again and repeat procedure of ferment supply valve adjustment. Continuous distillation machine, switch off procedure.

If after switching off the continuous distillation machine is meant to be used again for example: not all ferment was processed, and then switch off procedure will require only closing all valves - water supply, ferment supply, power off steam generator and low pressure pump. To start distillation again just open water supply, switch on power for steam generator and low pressure pump, and repeat the ferment supply valve adjustment.

If all ferment is used and spirit/ferment heat exchanger is started to heat up because there is no ferment to cool vapors down - first switch steam generator power supply off, second- close water supply to water distribution vessel, third fill the ferment storage/distribution vessel with small amount of fresh water (30 - 40litres) and open ferment controlling valve fully to allow the water to run through the internal space of entire distillation machine. (Originally the waste releasing tube is connected with drain via any flexible or metal tubing; the drain can be up to 10m away from the distillation machine. The waste releasing line must be at floor level and drain must be lower than waste releasing line).

Once all water is run through the continuous distillation machine the low pressure pump must be switched off while ferment distribution valve and empty ferment storage vessel's valve are open to allow al liquid from distillation machine to run out of machine back to ferment storage vessel.

RECEIVED at IPONZ on 26 November 2010 When all liquid is get out of machine (maximum 2.5-3Liters) then valve on ferment storage vessel is getting closed down the connection between low pressure pump and ferment storage vessel is detached and storage vessel is getting cleaned separately. Then water from water distribution vessel is getting drained out.

Description of construction of spirit fractional purifier. Further - rectification machine or rectification column.

The number of rectification machines were build though all of them are share one working principle and the construction of dephlegmator, internal fillings of columns and construction of the batch boilers were different. The difference of construction was dictated by the size of the rectification machines, power consumption and application.

Description of dephlegmator used for rectification machines.

The difference between dephlegmator used for continuous distillation machine and rectification machine is that dephlegmator for continuous distillation machine is a blind type - absolutely uncontrollable and designed to supply all the spirit evaporated during distillation to prevent the spirit loss -the main purpose of continuous distillation machine is to separate the ferment from spirit (to strip the water from spirit). The dephlegmator used for rectification machines are designed to be controllable and supply as much of spirit per unit of time as one can wish for within the capability of rectification machine, plus it can control the quality of spirit and speed of spirit flow without any pressure build up in a column.

The main purpose of rectification machine is to produce the highest quality of spirit possible at highest percentage possible plus the ability of rectification machine to fractionally separate impurities naturally accruing in raw spirit such us methanol, butyl alcohol and esters.

The following is the description of the rectification dephlegmator for the smallest rectification machine build. The construction of this type dephlegmator is almost similar to the dephlegmator of continuous distillation machine it has the metal coil wrapped around the distillation column body that penetrates the body of dephlegmator this is only similarity including shape of dephlegmator. The difference is that through the coil runs cold water plus the coil's inlet and outlet are located outside of dephlegmator. there is 16 RECEIVED at IPONZ on 26 November 2010 spirit level control pipe installed that helps to observe the level of spirit in the dephlegmator, moreover the top end of the distillation column that penetrates the dephlegmator from underneath is part of dephlegmator itself and equipped with passages for spirit to run back into the column, plus equipped with the spirit collection tube and valve that are located below the spirit passages level, thus this position makes it possible to control the spirit flow speed and amount of spirit that send back to the column for purification. The bypass system is located on the top of dephlegmator's body and connected to the spirit collection tube below the spirit control valve to make the system opened to the atmosphere to maintain the atmospheric pressure inside of column and perform the rectification at atmospheric pressure; moreover the open system is safe to work with. Unlike the continuous distillation column where is only partial condensation of spirit occurs inside of dephlegmator internal space and getting condensed completely in the heat exchanger, in the rectification column's dephlegmator condensation is complete and practically no vapor occurs thus the spirit collection valve can be left completely closed for hours and rectification column will work for itself producing and utilizing spirit inside the column without pressure buildup and no single spirit drop will be released until the spirit collection valve is opened. To achieve the complete condensation the pan like metal construction is covers the cooling coil outside leaving the coil and open end of the distillation column covered inside creating a gap between the distillation column outer walls and pan inner walls with the coil in-between. Thus spirit vapor is forced into the bigger space of dephlegmator through the gap around every turn of the coil where it getting completely condensed.

The second type of dephlegmator used for medium size commercial rectification machine with production rate of 12 Liters of purified spirit @ 96% Per hour and power consumption of 12kw per hour, equipped with two steam generators and coil steam heated 320L batch distiller. This machine is capable of 120L of purified spirit in 10 hours time.

From figures above can be seen that flow rate is quite intense and as long as only % of all evaporated spirit is taken out (quality purpose) and % is send back to column the construction of dephlegmator must be capable to condense 17 RECEIVED at IPONZ on 26 November 2010 effectively up to 48Liters of spirit per hour and not create any resistance or overpressure inside the column.

The dephlegmator build for this purpose is absolutely different from mentioned before, this high flow dephlegmator is constructed out of three sections where is internal section has a diameter of distillation tube the dephlegmator is installed onto. The middle section is build around smaller tube - the two round metal plates are drilled in the centre to accommodate the middle tube and drilled around the big centre hole to accommodate small diameter thin walled metal tubes.

The plates are getting welded to bigger diameter section of tube that will form a cylinder like construction with two drilled plates that are welded on both sides.

Then centre tube is inserted into central hole and the side that considered being the top of construction is leveled with inserted tube and getting welded around the edge of central tube and the edge of the hole of the tube is inserted into, so the opposite side is getting welded around the hole edge and the body of tube. Then two small diameter holes are getting drilled on top and low sides to accommodate water inlet and outlet. Then small diameter tubes are inserted into the small holes previously drilled around the bigger central hole, all tubes are getting welded around edges on both flat sides of the cylinder, the internal space of the cylinder will be filled up with water around small diameter tubes that are forming passages for the hot vapor out coming from the top section of distillation column.

One tube is attached so to form passage from the low flat side of the cylinder to the top outside section of the constructed dephlegmator this passage will form the bypass system to equalize the pressure inside the column and atmosphere.

After the middle section is assembled the low section of dephlegmator is welded to the bottom of the middle section, the size of the low section is halve size of the middle section with the same diameter and has a shape of a big ring. When the low section is welded onto the middle section of dephlegmator the bottom flat round piece of metal is attached to the low section this part has the c enter hole for the middle section of dephlegmator and two holes for the spirit collection tube and level control tube. After the 18 RECEIVED at IPONZ on 26 November 2010 low section is assembled then the top section must be completed the top section is consist of the halve size of low section and same diameter as middle section metal ring with two holes on opposite sides one for the bypass passage and another to accommodate the top level control tube, and the blank flat round piece of metal. The ring is welded on top of dephlegmator and the blank piece welded on top of the top section of dephlegmator. Construction of the rectification columns.

The rectification columns' construction is similar to construction of distillation columns, though there is some difference, the first difference is construction of the dephlegmator (was described previously), second there is no any heat exchangers on the bottom side of rectification column. The column has an open end (with the metal mesh installed to secure the internal filling) to the batch boiler. Through the spirit cooler/condenser runs cold water, and spirit collection tube at the bottom of dephlegmator is equipped with spirit flow control valve. The filling of the rectification columns is the same that used for continuous distillation columns-spiral metal rings, but for the small rectification columns were used packed fine stainless steel shavings. Description of construction of the batch boilers for rectification columns. The construction of batch boiler for rectification column as it seen on Fig. 3 Is obvious - it is cube shaped vessel (Cube shaped for the simplicity of construction, convenience of installation and floor space occupation) with filling opening equipped with threaded lid, threaded connection for the rectification column attachment, heating element and waste release valve. This design used only for small size rectification machines with batch boilers up to 50L capacity.

The construction of big size batch boilers is slightly different, though they are share the cube shape construction with small size batch boilers the method of heating is different. In the big sized batch boilers there is no direct contact of electric heating element with raw spirit. Instead of heating elements installed directly inside the batch boiler there are one or two sets of metal coils that occupy the internal space of batch boiler and open ends of the coils are located outside the boiler, where the top ends of coils are connected to the instant steam generation system that controlled by the floating ball water 19 RECEIVED at IPONZ on 26 November 2010 distribution system (the steam generator and floating ball control are described previously in the description of continuous distillation machine). The low ends are connected to the common water release system and breathing tube that reduces the possible pressure inside the system of coils. In addition the big sized batch boiler is equipped with level observing clear plastic pipe for the level control of the raw spirit inside the boiler. The principle of work of rectification machine.

The batch boiler is filled with the raw spirit (that was produced with continuous distillation machine and contains all the impurities) @40 or 50% alc/vol. The power is switched on and heating element or coil is heating the raw spirit inside of boiler. Through the spirit cooler that located under the dephlegmator, runs cold water filling the internal spice of the spirit cooler surrounding the coil, then water leaves the internal space of spirit cooler and trough the tube at the top side of spirit cooler directed to the low side of middle section of dephlegmator filling the internal space of the dephlegmator surrounding the center section tube and the set of small diameter tubes that connect low and top sections of dephlegmator. The water leaves the dephlegmator to a drain through the tube attached to the top side of middle section of dephlegmator collecting the heat along the way through the system. At the same time the spirit vapor penetrating the internal filling Of distillation column and reaches the dephlegmator where is getting condensed completely. The liquid spirit is partially escaping the dephlegmator through the spirit collection valve into the spirit cooler and partially returned to the internal space of distillation column. The ratio of spirit taken out and retuned back to the column can be controlled and is achieved by construction of spirit passages (directing spirit back to the column) that are slightly above the level of collection tube and by closing and opening the flow control valve one can create the overflow inside the dephlegmator and send spirit back into column. The spirit that is send into the column is condensed and cold running down the column meeting the vapors that are hot and in the state of gas, the vapor and liquid spirit are penetrating spaces between spiral metal filling and by meeting each other creating heat/mass exchange process where liquid forcing vapor to become liquid and hot vapor is forcing liquid to evaporate, as a result the only lightest vapors can reach the dephlegmator and at the RECEIVED at IPONZ on 26 November 2010 point of entry into the dephlegmator the temperature of vapor is equal to the temperature of boiling of the liquid forming this vapor. (The raw spirit is contains different impurities and all of them have different properties and temperatures of boiling so by knowing the percentages of liquids presented in mixture is possible to separate them physically with help of rectification column, moreover the amount of liquid in the batch boiler is certain at the beginning of distillation so by knowing the amount of liquid and percentage it is possible to perform precise fractional distillation or rectification).

The spirit that enters the spirit cooler is running down the coil and after being cooled is collected into the spirit collection vessel.

Exploitation of the rectification machine.

The following description of exploitation of small rectification machine and can be equally applied to any size of rectification machine described in present specification. Though the speed of spirit production will vary respectfully to the rectification machine size and power consumed, thus the amount of spirit taken from rectification machine per hour is depends on power the machine is consumed and equals to one liter of purified ethanol per kilowatt of power per hour. Or simply if the rectification machine consumes 2 kilowatts of power in one hour time the production speed of machine is 2liters of spirit per hour.

Fractional distillation (rectification).

Fractional distillation is performed with help of big rectification column.

Before distillation the total volume and percentage of spirit should be measured.

For example: you have got 6L of raw spirit at 50% alc/vol - make a record on a piece of paper: This note will required for the further calculations of fractions that going to be taken during distillation.

BEFORE FILING THE BOILER MAKE SURE THE BALL VALVE IS CLOSED To perform fractional distillation- take the raw spirit and fill up the boiler with it.

Please note that if you working with small amounts of raw spirit some water must be 6L @ 50 % 21 RECEIVED at IPONZ on 26 November 2010 added along with spirit to prevent the heating element burn out. The minimum amount of liquid that should be left in the boiler after distillation is around 7L, thus for example with 6L of 50% spirit should be added 5L of water.

Because - 6L of raw spirit multiplied by 50% of strength = 3L of 100% alcohol, so after evaporation there left only 3L of liquid therefore by adding 5L of water we increase the amount of liquid that will be left in the boiler up to 8L.

When you working with amounts of raw spirit at volumes exceeding 15L at no more than 50% ale no water required, just make sure that after the distillation has finished the sufficient amount of liquid still remain in the boiler. Foregxample-15L of raw spirit multiply by 48% strength = 7.2L of 100% spirit and 7.8 L of liquid. Thus you can perform complete distillation at once with small amount of raw spirit or make few raw spirit distillations to collect it, and make one fractional distillation with amounts of raw spirit up to 20L.

When you filled up the boiler with raw spirit and added water if needed so, it is time to close the lid and install the column, Apply rubber attachment of the cooling system on water supply and open up the water tap to allow water to run through the cooler, when water started to run through, it is time to switch on the power supply. Make sure that speed control valve on the side of column is closed. While the boiler is getting hot it is time to perform some calculations, this calculations is will make a guide of fractional distillation so you will know exactly how much of different spirits you going to take because you can not rely on a guessing at this stage. Below is the example of calculation that based on percentages of fractions presented To perform measurements you will need a lab glass(O-lOOml) and alcoholmeter (0-100%) 1st fraction -10% contains methanol, propyl and esters. 2nd fraction- 5% contains methanol, tracers of spirits listed above and ethanol. 22 RECEIVED at IPONZ on 26 November 2010 3rd fractions sum of 1st, 2nd,and 4th extracted from total of spirits calculated, less approx 20% 4th fraction- 3.5% contains butyl Use electronic calculator The actual calculation - example: we have 6L of 50% raw spirit so first we have to find the spirits total. To do so we have to multiply 6L by 50% = 6*50% = 3 so we have got 3L of spirit @100%. Now we will calculate the fractions of spirits presented in our total spirit.

Remember the note we made when filled up our boiler?! Now make a calculation and fill up the note We know that we have got 3L100% total spirits - make a record To find out the first fraction take 3L and multiply by 10% of meth presented = 3*10% =0.3L or 300ml- make a record To find out the 2nd fraction take 3L and multiply by 5% of 2nd fraction presented = 3*5% =0.15L or 150ml- make a record After we found out the 2nd fraction we should find the last 4th fraction and only then we can calculate the 3rd ethanol fraction that we are going to collect 6L (c 50 % =3L total 1st = 300ml meth. 2nd = 150ml 23 RECEIVED at IPONZ on 26 November 2010 To find the 4th fraction of butyl alcohol we take our total in this case it is 3L and multiply by 3.5% of butyl presented = 3*3.5% =0.105L or 105ml- make a record Now when we know the amounts of all impurities we can calculate the amount of ethanol that we going to collect for our further spirits production, to do so we must find the sum of all impurities we have got This are 1st fraction + 2nd +4th =300ml (1st) +150ml (2nd) +105ml (4th) =555ml of total impurities.

Now deduct the total of impurities (555ml) from the total of spirit (3000ml): 3L (spirit) - 0.555ml (impurities) = 2.445L of ethanol.

Now note that presence of esters and other spirits in the raw spirit are affecting correct alcoholmeter readings and alcoholmeter showing more spirit than it is, because esters are thinner, lighter and more liquid than ethanol and alcoholmeter is designed for ethanol reading not for esters reading.

Thus actual amount of ethanol less than result of calculation by approximately 20%. The last step of calculation is to find the actual amount of ethanol - in this example from 2.445L of calculated ethanol deduct 20% = 2.445L * 20% = 0.489ml, 2.445L - 0.489ml = 1.956L of real spirit could be taken Please note that 20% of deducted spirit is very close approximation and actual amount of ethanol spirit distilled should be rounded to 2L, because in our calculation we operating with 100% spirits but taking 96% spirits. So our table will be like below: 6L @ 50 % =3L total 1st = 300ml meth. 2nd = 150ml 3rd = ethanol = ? 4th= 105ml butyl impurities = 555ml 24 RECEIVED at IPONZ on 26 November 2010 By using the calculation pattern above calculate any percentages and spirit amount ratios.

Now the spirit hot and boiling in the boiler, the spiritous vapour is reaching the head of fractional distiller. The first indication of spirit condensation is liquid that can be seen in control plastic pipe on the left side of distiller head. Make sure that spirit collection valve between the distiller head and cooler is closed. 6L @ 50 % -3L total 1st = 300ml meth.(10%) 2nd = 150ml (5%) 3rd = ethanol = 2.445L-20%=1.956L (2L) 4th= 105ml butyl (3.5%) impurities = 555ml The Valve should remain closed at least 5 minutes to allow spirits to form a queue in the column. The closed position of the collection valve is horizontal to open turn the valve anti clock vice.

Regardless of valve being closed some spirits vapour will reach the bypass pipe and go through the cooler into collection vessel it is normal and do not indicates the fault of collection valve.

After 5 Minutes had elapsed start to turn the collection valve open , do it very slow the collection speed for this distiller should be between 12 and 14 ml of spirit per 30 seconds that equals to 24 or 28 ml per minute or 1.44 or 1.6 L per hour. Please note that actual capabilities of distiller is much higher and more spirit per hour can be produced but to maintain highest quality the collection speed must be as indicated above.

To adjust the speed of spirit flow uselOOml marked lab glass and simple clock.

RECEIVED at IPONZ on 26 November 2010 Once flow has adjusted - start to collect the first fraction of spirit that in the future will be used for technical purposes only, please note the first fraction is very rich wit methanol and can cause poisoning.

Then collect the second fraction that should be collected and added into next distillation batch, note that calculations should remain the same.

The third main fraction of purified ethanol must be divided into two stages. The first stage when 2/3 of calculated ethanol will be taken at speed of 12or 14 ml per 30sec, the second stage - after 2/3 of spirit already collected the flow must be reduced down to 7ml per 30secondc and remain at this point till the end of distillation.

When all counted for ethanol is collected then there is no point to carry on further distillation.

Because there is no real use for butyl alcohol, that will start to evaporate and get condensed in the distiller head, just finish the distillation when all calculated ethanol is taken. Drain all left spirit in the column into the separate vessel; take a small portion of drained spirit mix it with same amount of water and taste it if its tastes ok for you then add the drained spirit into the ethanol collected. 26 RECEIVED at IPONZ on 26 November 2010 Use table below to calculate the ratio of water and spirit to obtain the needed strength of alcoholic drink.

In most cases you will work with 95% spirit so first measure the amount of spirit you have got in this case @ 95% than choose what percentage you want this spirit to be after dilution.

After that find the figure crosswise on the table, and multiply the amount of spirit by this figure The result must be divided by 100 and you will get amount of water to be added to your spirit to make planned percentage. 27 RECEIVED at IPONZ on 26 November 2010 Example: we have got 2L of spirit @ 95% and we want to make 40% drink so we will need to find the amount of water to be added thus 2L of spirit must be multiplied by figure that cross match 40 on a vertical axis - the figure is 144.4 so 2L * 144.4 = 288.8 then divide the result by 100. 288.8-r 100 = 2.888L of water that will be added to spirit to make 40% drink in this case you have got 2.888 + 2 = 4.888 L of 40% alc/vol drink.

Detailed description of the filtration unit.

The range of different filtration units were build and though all of them are different size they are share exactly the same design and working principal. The following description is the description of construction and exploitation of smallest filtration unit built and can be equally applied for bigger size filtration units mentioned in current specification.

The filtration vessels are having a shape of standing upright rectangular. The rectangular shape is chosen due to simplicity of manufacturing and because it is most convenient shape for indoor installation (buildings are designed to be square inside so most of indoor applications including furniture , tables computers and electronics are square shaped) to be installed in any corner of the building the filtration unit could be installed in. The upstanding rectangular tanks a standing on frame like stands. The stands are also used for supporting the low pressure centrifugal pumps and rechargeable filters underneath the filtration vessels. The vessels are equipped with detachable screwed on lids on top of the vessels each lid has a small opening in a centre for the pressure equalising between the internal space of the vessel and atmosphere. The big size filtration vessels are equipped with the cross bars that are welded inside the vessel's internal space and connecting the walls of the vessel to each other to reinforce the construction of rectangular tank.

On the sides of both vessels there is level control clear plastic tube that helps to observe the level of liquid in the filtration vessel. At the bottom of both filtration vessels there are ball valves attached via threaded connection to the vessel, the low pressure centrifugal pumps are connected to the ball valves by intake end. The outlet ends of pumps are connected to rechargeable filters. 28 RECEIVED at IPONZ on 26 November 2010 The first stage filtration vessel is equipped with the set of two stainless steel tubular filters connected to each other in series and filled up with activated carbon and filtration grade glass, the carbon is getting replaced prior each filtration and filtration glass is unloaded from filter and washed in fresh water after every 10 filtrations. The second stage filtration vessel is mostly used as a storage vessel and equipped with the rechargeable cartridge filter. The cartridge of the filter is getting replaced once a year. Through the filter the second stage filtration vessel is usually connected to the bottle filling line or equipped with bottle filling nozzle.

The working principle of filtration unit.

From spirit dilution vessel the spirit at desired percentage is pumped through the low pressure pump into the opening on top of first stage filtration vessel, and fills the vessel. The control of spirit level in first stage filtration vessel is performed with help of level control plastic pipe located on the side of filtration vessel. After the vessel is filled up with spirit the low pressure pump of filtration vessel is switched off and the lead is applied onto the opening of first stage filtration vessel. The carbon filter is filled up with a fresh carbon, the plastic tube connection between the carbon filter and the glass filter is disconnected and directed into the small collection vessel the control valve that locates between the bottom of the filtration vessel and the carbon filter is getting opened at full and spirit starts to run through the carbon inside the filter at low speed because of carbon resistance, and started to flow into the small collection vessel. Allow the spirit to flow into the small collection vessel until the spirit is becomes visibly clear ( usually 200ml maximum), then without closing the valve underneath the filtration vessel the plastic tube connection between the carbon filter and the glass filter is applied back to connect two filters and the plastic flexible line that connects the first stage filtration vessel and the second stage filtration vessel is directed into the small collection vessel but not the same that was used for the spirit collection from the carbon filter. The line is directed into the small collection vessel and at this stage the low pressure pump is getting switched on. At the increased speed the spirit is starting to flow into collection vessel and spirit visibly is little bit cloudy, so allow at least 3 Litres of spirit to flow into the small collection vessel, at the same time the threaded lid on top of the second stage filtration 29 RECEIVED at IPONZ on 26 November 2010 vessel is opened to accommodate the spirit outlet tube (the tube is equipped with ball valve and getting closed prior the shifting from small collection vessel into to opening in second stage filtration vessel), the spirit outlet tube is directed into the opening of second stage filtration vessel allowing the spirit to flow into the second stage filtration vessel, at this point the spirit that was collected in the small collection vessel from the spirit outlet tube is poured back into the first filtration vessel through the any appropriate size funnel. The spirit collected from the carbon filter is stored in the separate vessel getting settled and usually redistilled together with the raw spirit or added into the ferment before the distillation. After the second stage collection vessel is filled with the spirit the first stage low pressure pump is getting switched off, the spirit outlet tube is removed from the opening of the second stage filtration vessel and the threaded lid is reapplied onto the opening on top of second stage filtration vessel.

The second stage filtration vessel is generally used as a storage vessel and filtration performed on demand when the bottling is occurs, to use the second stage filtration vessel one should first to switch the low pressure centrifugal pump on, then open the valve located between the pump and bottom of the second stage filtration vessel (the spirit outlet is connected to bottling device or nozzle) the bottling nozzle is directed into a bottle or whatever collection vessel (drum), the nozzle is getting opened, the spirit is flows through the low pressure pump then through the porous filter into the spirit outlet line, the nozzle is remains opened until a collection vessel, a bottle or a drum is filled with the spirit at desired level,, then nozzle is getting closed the low pressure pump is switched off and the valve in-between the second stage filtration vessel and the filter is getting closed.
