DOSER DEVICES AND POWDER PRODUCT CONTAINERS
The powder containers are made of plastic material, certified
as being food-safe and inside they are fitted with worm
screw systems (auger) to meter the powder.
According to the auger output, depending on the rotation
velocity of the motor, a time in tenths of a second must be
set in the SW to obtain the required amount (times to obtain
average doses for the specific countries are set by default).
The dose can be changed according to needs, setting
different times; however it must be taken into account that
the dose need to be in the right proportion to amount of
liquid used, therefore the time setting cannot be longer than
the one for dispensing water, otherwise there is a risk of
clogging up the mixers.
By default any time setting greater than the one for
dispensing water is “CUT”.
Specific containers holding specific products are fitted with
systems (defined as whippers), which are used to prevent clogs or compacted product.
The ratiomotors used are of the induction type (without commutator or brushes) powered with 230 V AC, with
good pick-up torque, long operating life and with overheating protection on the coil.
Ratiomotors with different speeds are provided for specific markets and products, especially conceived to obtain
the best results with any powder used. This aspect should be taken into account when replacing the motors.
