I'm trying to upload a video file, can you advise which file extensions are good to use, i've tried .MOV and .AVI and they are not allowed.

Thank you

I’m not sure you can upload a video to the site. Typically videos are hosted on an external site, like Youtube or Vimeo, and then linked with a URL tag.

But certainly either .mov or .avi video files would not be allowed because both of those file specs are uncompressed. I would think you would need to compress them to a .mp4 at the very least.

God I do love this build thread. I only hope some cowboy doesn't try to copy it and torch themselves.

Hello

So final, and it never is, final finishes touches to the ageing vessel, I soldered on a section of CSST to the air input, I was getting some slight drain in to the air line from the tank, and instead of fitting a one way valve, think that would be useless plus, did not want to introduce any rubber in the line as most of the valves have a rubber seal.

I also added a weight relief air line holder to reduce any joint tension on the air output and air input.

There is a quick release connector on the vessel side I fitted originally to allow easy cleaning and moving around, and fitted a quick release on the controoler side air line as well this allows me to remove the air line totally without stressing the output or input connections.
IMG_4126.jpg


A couple of better views of the airline connections fitted so you get the full picture.

A view of the air flow in the tank, its just water in the take for testing.

I finished the spirit run on the rum Sunday, ran 2 sets of rum in the ultrasonic tank before adding to the ageing vessel, before adding the rum to the ageing vessel with oak.

I ran the vessel in manual mode for half an hour late Sunday night as I will be thinking more on the heating cycles and oxygenation cycles, you would have thought I would have that sorted, but, its not that simple, the heating cooling cycles are more straight forward, but, I've never been able to find any qualitative information on how much oxygenation to give ageing, they is a reasonable amount of head space in the tank , I originally had the thought of every other day to have the air line activate but, I'm thinking half hour per week would be more like the normal, the pump delivers a lot of air even when backed off to half power, and one of the things I have to consider is evaporation, there is a really nice amount of natural reflux that condenses on the tank lid. So, its going to be a learning curve for sure, I've got a reasonable amount of ageing experience in glass carboys and have tried the nuclear method.

We shall see how far the rabbit hole goes.

I'll try and feedback on this build on the development of the rum in the vessel, but, this is only the second rum I've actually done, most of my work is Gin, Vodka and Brandy, but, my brother in law has come back from the Caribbean with an appropriate amount of rums for me to reference to.

Hope you've enjoyed the build as much as I have in building it, if anyone out there want to do something similar, and needs any advise then please ask, please please, do not cut out any of the safety aspects of the build, and as normal advise, you are working with electricity, if in doubt don't do it.

I've mentioned before, I'm looking to incorporate, eventually some of the safety aspect from this in to the main controller.

Cheers

Build is complete but am redoing all my instrumentation for Ex (Atex) compliant.

I am wetting my pants as to what money is required, e.g. the Ex rated level switch is 7 times pricier than my standard EH probe. Other instrumentation items also have massive Ex costs. I have 7 temperature transmitters, 1 pressure transmitter and 1 level switch on the still. Now to add insult to injury for every instrument you need to additionally have an isolation barrier for each and this individual cost is similarly huge. For digital outputs e.g. valves, I have swapped electronic for pneumatic so as to avoid stupid costs.

So am battling all above.

I’m interested, when you say transmitters, this to me suggests they are, well, transmitting as in RF radio frequency, rather than hard wired, send a picture of them if you could,

Cheers

Hello

4 days in and just 2 heat cycles and 3 oxygenation's, I'm getting my head around the process, it takes 3 hours to get from 15 degrees to 60 degrees C, I'm setting the programmer on a daily basis as the week goes by, I'm only oxygenating for 2 minutes per day and only when the temperature is below 20 degrees C, this should minimise the evaporation as oxygenating the rum when hot is just going to push out the high proof vapour out of the vessel.

So, the air pump is set to come on at 2 mins to 7 at night say on the Tuesday, at 7 the air pump turns off and the timer for the heater turns on for 3 hours and 5 mins, and hits 60 degrees after around 2 hours 50 mins, and is maintained at 60 degrees by one of the STC-1000 and turns off at 10:05 PM.

The rum is still at some 27 degrees C at 7:30 the next morning with an ambient of 14 degrees C, so a nice gradual drop of of temps, it takes till 1 ish in the afternoon for the temperature in the vessel to below 20 degrees.

I plan to have this happen ever other day, with 2 mins of oxygenation at a preset time every day at say the same 2 mins to 7 in the evening and again shuts itself down after the pre-set 2 mins.

So, what do we look like after the 4 days, if you compare the colour to that of the one above from 3 days ago.
IMG_4137.jpg
Colour looks good, taste is very pleasant indeed.

I have also started a rum essence, with 375ml of 60% ABV rum and 375ml of the 4th backset from the previous rum distillations, I will be letting the essence settle out, then rack off to another bottle a couple of times, then add this to the some of the final rum for a dark rum, the flavour is really really good.

ABV check of the rum in the vessel is currently 60% as of this morning. Will monitor this every other day.

All in all going to expectations so far.

Cheers

Tony

Great thread and build Tony. Keep us updated on how the rum turns out.

Hi Tony

Presently all hard wired and transmitters are 4-20mA. I have in the past two weeks also been looking at wireless transmitters.

As drawn, If the SSR fails with the output shorted.
None of the safety devises would work to shut down the heat.
I'd recommend an E-Stop circuit with a latched relay.
That way if anything fails, the power is turned off.

Shadeylane

You are correct, if the output shorted the primary safety detection would not shut the SSR down, you are looking at the concept diagram, a more detailed one was listed later, it is possible for an SSR to fail in a closed condition, not the most likely but possible.

This would not mean that the heater was on permanently, as in the later version you see the program timer is after the ssr that controls how long the heater can be on for, in addition. There is a visual green led that is lit up if safety is ok that I would have to deliberately ignore.

In addition to that, a separate stc-1000 controls the power to the power supply that shuts down the heater when it gets to a pre set temperature.

I will look at your suggestion and weigh up any benefits, one of the benefits I need to have in any change is no relay spark gap possibility, as at the min, if in the highly unlikely event of a ssr failing in a closed condition and me ignoring a safety light off condition, and what would have to be a simultaneous failure of the program controller, and a failure of the temperature controller, listen, this is mark 1. And all this could happen and I’m giving thought to how I could over come the event you describe, for sure this will be keeping the safety of an ssr.

Thank you for your comments I will look at your suggestion,

Cheers

Tony

Can you PM me a copy of an e-stop circuit with a latched relay please, I’m sure this is lost in translation of terminology, but, ive looked at a few diagrams and they are similar to emergency power out circuits in the U.K., which the SSR side replicates, the benefit of an old school relay of cause is the fault condition is less likely to occur as a spring pulls the contacts back, I offset this against no spark gap. Now I am venting any possibility of vapour away from the controller to another vessel, which would help when using a physical relay.

What I could look at, if you look at the more detailed diagram later in the post, all the ssr does really is to power up after the program controller a 12v power supply for the heater, I could incorporate an “and gate” to detect the 12v from each control power supply, but, have a look at the more detailed version diagram.

Cheers again

I’m not pushing a point here at all, you bring a valid point, but, worth a mention, should there be a simultaneous failure of the ssr in closed and a failure in the program controller, and a fault condition, I would not only have to ignore the bright green safety on led not being lit, but, in the detailed diagram I would have to have ignored the two bright red leds telling me that power is applied to the heater and the power meter telling me I’m consuming over 200 watts.

Also, this is a 40 amp ssr fitted to a thermal heatsink pulling a max of circa 1.6 ish Amps at 240v, over spec for any terminal failure due to stress.

Again send the diagram and have a look at the later one my friend

Cheers
