What's the difference between agglomerated and freeze-dried coffee?

Agglomerated coffee is coffee to which, after being dried, powder is added, and then
an additional steam belt or steam curtain process is applied, which causes the
particles to bind together, thus forming granules. Freeze-dried instant coffee is
manufactured using an innovative technique to dry the coffee. The thick,
concentrated liquid coffee is frozen at very low temperatures. The water is extracted
in a controlled process, yielding large, golden coffee crystals.
