- Ultra Low Energy Dryer
RHH - Retention Hopper High Level
format: xxxxx (lbs. or kgs.)
function(s): Retention hopper fill dispense target. This value is typically slightly higher than VCH to
ensure that 100% of the vacuum chamber contents dispense into the retention hopper.
RHL - Retention Hopper Low Level
format: xxxxx (lbs. or kgs.)
function(s): 1. When the dryer is started, if an amount of material equal or greater to this level is
detected in the retention hopper, a “Warning: Material in Retention Hopper” message will
pop up.
2. When in Clean-Out mode, the vacuum chamber dump valve will not open
automatically until the retention hopper weight reading is at or below this level.
3. When the dryer is running, the retention hopper must be depleted down to this level
before a vacuum chamber dump is allowed.
BLK - Bulk Density
format: xxxxx (lbs./ft
3
or g/L)
function(s): User-enterable material bulk density. Setting this parameter to match the material being
dried ensures that a fill weight that could potentially overflow the vacuum chamber
cannot be entered. Note that this parameter has no effect on drying.
VFR - Vacuum Chamber Fill Rate
format: xxxxx (g/sec.)
function(s): Learned flow rate of the vacuum chamber fill valve. This parameter will automatically
adjust over time. As it adjusts, vacuum chamber fills will converge on the targeted fill
weight.
VDR - Vacuum Chamber Dump Rate
format: xxxxx (g/sec.)
function(s): Learned flow rate of the vacuum chamber dump valve. This parameter will automatically
adjust over time. As it adjusts, retention hopper fills will converge on the targeted fill
weight.
Note: this parameter is typically set to 00000, which means that rate learning does NOT
occur, and vacuum chamber dumps will terminate on low flow or high level (RHH).
Manually setting this parameter to any value other than zero will enable rate learning.
