Problems with the air supply to the drying hopper (I.E: clogged filters or blocked drying air
supply line) initially show up as a reduction in the T5, T4, and eventually T3 temperature
readings since the air flow is no longer strong enough to carry the drying heat up through
the hopper. The remaining probes will also decrease in temperature as the problem contin-
ues, even though T1 and T2 continue to display levels close to the process temperature. This
can be a very gradual reaction to filters gradually becoming clogged.

NOTE: A decrease of T3 (as described above) can also be the result of an increase in through-
put or an increase in the quantity of reground material being dried in the hopper. Increasing the
quantity of regrind decreases the bulk density of the material being dried.
