Right we are making lavender oil, we have grown these on the front garden A few critters in this we are removing all of the seeds and as you can see and as you can see they are already collecting in the bottom of the in the bottom of the tub and these are what we have pulled off the ears. What we have prepared earlier and the left over stems from the ones we have already processed and pulled all the bits off to make our still we are going to be using a pressure cooker The type that fits on a gas ring The pressure-cooker valve as you can see here will be joined with a piece of hose, this is just a bit of hose we have found in the shed it fit’s quite snugly on the valve and this will be sealed with a jubilee clip and it will be joined to copper pipe We need to take our 10 mil copper pipe and we need to form it around something large enough to avoid creasing the pipe We are using a propane gas bottle Just gently roll the pipe around the propane bottle, pressing down on the propane bottle be very careful not to crease or kink the pipe, fill the pipe with dry sand and tape the ends to prevent kinking. Leave a fair amount of straight pipe on the ends Obviously will have to have a connection to the pressure cooker should just make sure it’s nice and tight around the bottle little bit of a kink there. dog snoring in background Now this will be our cooling pipe Not a great job, I,m sure if you have got the patience you will make a better job than I have this is the set up we have made and as you can see we have connected the copper tubing to the top of the pressure cooker And we have formed a coil that sits snugly in the washing up bowl which we will fill with cold water in and then the take off point again we’ve bent around at the end
and this will decant into whatever vessel we collect our distillate in The idea is that the heat produces the steam and that the volatile oil will be produced and condense in the cooled copper tube and then percolate out into the vessel. Into the pressure cooker, throw some lavender heads You can fill the pressure cooker up making sure that there are no stems that are going to affect the seal of the pressure cooker So just remove any stems from the top Add hot water out of the tap you are going to get a few critters in there but I wouldn’t worry about that add a little bit more You don’t want to over fill it because we want steam not water so we are down well below the lid Make sure that the pressure cooker is nicely sealed you can see we have a primitive set up There’s the washing bowl filled with cold water and there’s the pressure cooker and we need to light the gas the object is to bring it to the boil and turn it on to simmer and we need very little heat obviously if you have it too hot, you will get water through the pipe rather than vapour gently bring it back up to the heat, to the boil on a low gas making sure that we don’t burn as this will taint the oil so the object is not to as soon as we see steam coming out of here, we will close the valve with a little bit of blue tac and we should see the distillate percolating down into the demijohn So we have had to improvise, because we still had a leaky valve we have put more blue tac around the valve with some tape around Yes, its working and the outlet pipe is very hot and the rest of the coil is nice and cool cooled by the water and we should see some distillate dripping from here very shortly We can see the water now you can see that it’s oil based later we will have to remove the oil from the top of the water so our little make shift still, this still is working a treat we had a leaky valve on the top which we plugged up with some blu tac and tape There is a weight here for a safety device and as you can see here the gas is really low and the heat is being transferred to the water, which cools down the steam. and we are collecting it in the demijohn A good tip is to take off the warm water from the top of the washing up bowl talk that the washable and you can
replace you then you can replace it with cold water the hot water always floats to the top Loud snore That’s my dog you can hear in the background Now we will replace the hot water with some cold water not very high tech, I know but it does the job our still is working nicely see the point proven Washington won’t
become you can feel the pipe entering the washing up bowl becomes very hot and the pipe leaving is cold with the pressure cooker before using it
make sure that the safety weight is working general no problem with these but it’s always wise to check by using blu tac over the other safety valve it will easily pop off the blue tac if pressure increases the oil is forming nicely on top of the water when you start using the still it will take a while to fill up the tube coils with distillate another safety check we need to make is to blow down the tube to make sure it is clear before using it to make sure that it is free and has not got any kinks in it that could cause back pressure in the pressure cooker the milky looking water below the oil surface will actually make a good air freshener so it can be used in an atomiser or a spray or you could add a little to your detergent in the washing machine ideal for washing the dogs bedding I have just taken a small glass and you can see the oil forming nicely on the surface this is a good test to see if you have extracted all of the oil from the lavender if you test a glass full and there is no oil, it is time to do another batch this is the third batch, as you can see it is just starting to distill at first you can have a very high yield of the oil to extract the oil from the water what we did was siphoned off from underneath the oil the distillate or the scented water into a plastic milk bottle what was left we poured into a long narrow necked bottle this is a cyder vinegar bottle and as you can see we have a little bit sediment there is the distillate, the scented water below and that’s the lavender oil on the surface. To separate the oil, I use a 50 mil syringe body to draw up the oil, let stand in upright position and eject sediment and water keeping upright.
