Molecular sieves are said to be
those type of desiccants which although has almost same appearance with that of
silica gel but has different completely different properties as compared to
silica gel. This desiccant is produced synthetically with the help of metal
amino silicates. Molecular sieves are absolutely safe to use
with the food items as it is absolutely nontoxic but at the same time are
highly porous. It appears to have a pinkish color, tiny opaque beads which have
several internal cavities, connected with each other with the help of internal
window openings.
The other type of desiccant is
dehydrated ethanol. Ethanol dehydration means a process where the water
molecules or something equivalent to water molecules are removed from the
substance. Ethane and water is produced by dehydrating ethanol by heating it
over certain temperature with sulfuric acid. The vapors of ethanol can be
easily dehydrated by passing any type of heated catalyst, which will produce
ethane gas. This process is also called as ethanol drying.
