powder mix. Table 2 lists the mass used for different compositions
of P/S and O/S mixes. It can be seen that in case of P/S mixes when
the salt concentration was equal to or more than 50% by weight in
the binary mix the mass used was double the amount (2 kg) as
compared to those with lower amounts of salt. Similarly in case
of O/S mix the total mass of powders inside the mixer was 600 g
when the amount of salt was higher than 50% by weight as compared
to 300 g for when salt concentration was lower. Such big difference
in the total mass of powders used inside the mixer is due to
the large variations in the bulk densities of the powders used.
Oregano has very low bulk density (Table 1) and thereby the total
mass of the powder mix inside the mixer is drastically reduced. In
order to cover the blades of the mixer and get sufficient powder for
mixing, the total mass for each type of binary mix had to be
