A Flash Evaporator?

 

We have one in our school, and my teacher was going to throw it away, i put it back in his room though, because i thought that i might as well just ask here to see how it works, and what it does

 

here is a link, we have the exact same one:

right here

 

thanks

Very simply put, what a flash evaporator does is it compresses a liquid and then heats it up before allowing it to expand from a nozzle. The sudden drop in pressure causes the liquid to vaporize. Typically, if the liquid is a mixture of two or more components, one of which is more volatile than the others (has a higher vapor pressure at the nozzle temperature), then this volatile component vaporizes out of the liquid, and the liquid gets more ocncentrated in its less volatile components.

ohh ok,.

 

cool, thanks

Think of it as a not so cheap still.
