Solenoid takeof valve

[Crazylegs]

Hello Everyone.

i bought the book "Designing and building automatic stills - By Riku Version 2.

and i see that he have made a Lacretz Mk2 column. whit a Solenoid takeoff valve.

He made a Script for computer to open/close this valve. but i dont want to use a computer.

do anyone of you smart guys know how i can do this? im thinking abaout using a Sestos d1s Pid kontroller? but dont know how to set it up.
i event dont know if i can use this PID. maybe i have to buy another one.

Hope somone can help me.

PID is of no value for distillation since it controls temperature, whereas POWER input control is required.

Re automation; distillation is dangerous and should be supervised directly at all times, any attempt to automate processes should keep this in mind. That being so, there isn't tremendous value in building such system at the hobby scale.

Stay safe and have fun.

Hello Expat.

This is not for making it automatic. But for making Pure vodka. And it's a must to have this valve. I still need to watch the cooling temp so it dont go over/under 60°. And this i have to do manualy.

Huh? It sounds like you’re trying to automate the system.

And it's a must to have this valve. I still need to watch the cooling temp so it dont go over/under 60°. And this i have to do manualy.

Are you trying to throttle the cooling water...or regulate the heat input?

You DO understand that the boiling point of the boiler charge will naturally increase as the run progresses, right? So, at some point trying to hold a vapor temperature constant will result in diminishing vapor production to the point that you’ll leave a lot of good alcohol in the boiler.

You need to do more reading on the fundamentals of alcohol distillation.

Designing and building automatic stills

Sure seems like automation.

Sounds like he's trying to automate one aspect of distillation for 'optimization'. There is nothing wrong with that. It is similar to using 'technology' to vary the amount of heat that is introduced.

I paid for that book and joined that forum, but never really got deep into understanding the method using that solenoid. If the method works ... awesome!

Without using a computer to run it, you would likely be able to use a 'Raspberry Pi' to run it. You would need a computer to write code and load the code onto the Raspberry Pi.

There are reasonably priced, tiny, Windows Micro Computers that could run it using existing/available code.

Dspr400

Two versions of the Distilling Controller are offered at this time. DSPR220 is the standard model with one SSR control output. DSPR400 is the advanced model with two additional programmable relay outputs. These relays can be programmed to engage at specific temperature or time. They are very versatile and can be used for many different types of applications. Following are some examples.

Thanks for understanding. Yes i was thinking about raspery pii or arduino. I talked whit a frend yesterday and he was gonna help me to program it.

Yes, I forgot arduino. Good call. All are very interesting gadgets. I've always been interested in them, but never played with them.
