That really looks like a fun environment to work in! Though, the pictures still don't explain how dry ice is actually made, its pretty fascinating to think about what you might use to freeze CO2 gas...
Yea its really fun to work here!
although its hard to explain the chemical process, but to educate some...
This is the process of the dry ice.
- Solid changes to Gas
- Gas changes to Liquid
- Liquid changes to Solid
Much different than your typical ice, but thats the reason companies use dry ice instead regular ice, it evaporates instead of melting. and leaves no mess behind, also stays much colder lot longer.
In solid form (dry ice) it is roughly 109 degrees below zero!
Now, I really dont know exactly the total process of how everything is made, because i only deal with the solid and liquid processes.
But from my understanding Ammonia is used to change the Gas into a Liquid. Thats about all i know.. lol..
But to get the liquid to a Solid, it is fed into those machines you see, and I believe once the liquid has contact with oxygen it becomes solid. Least thats what i believe happens. The liquid becomes a snow/powder which these machines press into pellets.
The process you see here is simply the only process that i deal with, the liquid to solid. Goes from liquid to a snow powder and the machines are what is making the pellets. Block ice can also be made, we will be getting the machine press for that in a month or two! :drool:
