Dispensing System
The dispensing system consists of:
• Brew valve
• Sprayhead
The dispensing system is what makes the brewer a coffee brewer. It dispenses the hot water over a bed of coffee
grounds to create the product.
The AXIOM
®
usesagravitydumpvalvesystem.Duringthebrewcyclethebrewvalveopensallowingwatertoow
from the tank and out the Sprayhead. The control board opens and closes this valve according to perimeters pro-
grammedintothecontrolboardbasedonaspecicrecipe.
While the dispensing system works much the same way as any other BUNN
®
gravity feed brewer. One major differ-
ence can be found that’s cutting edge technology to combat lime scale buildup within the hydraulic system.
BrewLOGIC
®
utilizes2liquidlevelprobes,asdiscussedearlierthelong(LP2)probeperformsthestandardtankll
when the control board calls for water. When BrewLOGIC
®
is activated and calibrated as earlier discussed the tank
waterismonitoredfor“owrate”outofthesprayheadusingamathematicalalgorithmthatwasdeterminedduring
calibration.Iftheowratefromthesprayheadistooslowortoofastwithinthersttwocycles,thecontrolboardwill
adjust the overall brew “time” to compensate.
