Thermal E. : Heating a container of the brine to drive off the water.
Vacuum E. : Pumping the air out of a sealed container of the brine, allows the water to evaporate more quickly at near room temperature.
Mechanical E. : ? Perhaps it is mote formation by evaporation of mechanically formed droplets? (See Cyclic Salt) Wikidity (talk) 22:42, 7 May 2011 (UTC)[reply]
None of this is really secret. I've been working on a rewrite of this article. Three sources come to mind:
The Diamond Crystal Salt company began in 1886. That's when John and Louis Alberger, together with Charles Moore and Horace Williams patented a new process for making salt in St. Clair, MI. This Alberger® salt process made it possible to create unique-shaped crystals with numerous facets. The result was an amazing salt with extraordinary adherence, blendability and flavor. Diamond Crystal® Salt... A rich heritage since 1886.
Those sources all contain good information but I do not find any of them presenting an explanation of what mechanical evaporation is. I am also curious as to what this process is which makes strangely shaped hollow salt, and would love to see a good source. Blue Rasberry (talk) 10:45, 8 May 2011 (UTC)[reply]
The article might have be wrong about the shape. In one of the photos in the sources, they claim it is "pyramidal" (and stepped) and "flaked" and there is a photograph to that effect. The Cargill plant dries and mechanically manipulates the salt as a part of their unique process, which dates back over a century. How they do that may be considered proprietary, so I won't go into it further. Having seen the operation, that's as far as I am willing to go. I assume that there is more in the patent application, which could be considered to be a good source. 7&6=thirteen (☎) 11:45, 8 May 2011 (UTC)[reply]
Mechanical Evaporation is also referred to as https://en.wikipedia.org/wiki/Vapor-compression_evaporation
This is also a similar physical process used in Air Conditioners and modern Refrigerators for https://en.wikipedia.org/wiki/Vapor-compression_refrigeration - It has been too long since my school days to define the "physical" in this case with accuracy. But if I recall somewhat all of these processes involve heat, however, in these cases we are also needing energy/work from a compressor to do the actual concentration {crystallization or chilling}. Hope this helps. 80.5.219.60 (talk) 18:26, 22 January 2016 (UTC)[reply]
