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 flow

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 specific 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 fill

when the control board calls for water. When BrewLOGIC

is activated and calibrated as earlier discussed the tank

water is monitored for "flow rate" out of the sprayhead using a mathematical algorithm that was determined during

calibration. If the flow rate from the sprayhead is too slow or too fast within the first two cycles, the control board will

adjust the overall brew "time" to compensate.
