7. Dosing of the Acid
a) Determination of the Moisture Content of the Grains
Initially, it is necessary to determine the moisture content of the grain using a
Moisture masuring device.
b) Quantity of Propionic Acid needed depending on the Storage
Time
For the determination of the quantity of acid needed (1/100 kg of grain) in
Dependence of the moisture content of the grain and the storage time, please
refer to the quantities recommended by (see page 8, Abb. 2).
c) Conveying Capacity of the Outlet Auger
The conveying output of the auger depends on the position of the slider, the
inclination of the auger, the moisture content of the grains, the amount of
extraneous matter, he grain size and form (wheat, corn) and the 1000-grain
weight. It is best determined by performing a 30 second trial run. This value
converted to 60 minutes results in the output per hour. Perform the trial run
two or three times and establish an average value to calculate the conveying
capacity.
If any of the above mentioned influence factors change, repeat the trial run.
In order to be able to perform the trial run for the measurement of the auger
output
without the PKT-unit, the screw elevator is directly connected to the
mains (extension cable).
For PKT-devices which are connected to a existing auger for operation,
The conveying output must be measured with the same method.
According to BASF, the further conveying with a blower requires a quantity
increased by 10 %.
d) Determination of the Acid Quantity
For the determination of the acid quantity to be injected stated in liters per
hour (see table 1, Abb.
2 ).
