Water for brewing is contained in a 200 ounce stainless steel tank. This tank contains a
1680W @ 120VAC heating element that is powered by the line voltage into the machine.
The heating element is controlled by the control board through a mechanical relay.
The control board monitors the water in the tank by a temperature sensor that is in
contact with the water. This temperature sensor is a digital thermistor; the control board
reads the temperature as value of resistance/voltage. The temperature sensor allows
the control board to trigger the heating element triac when the temperature drops below
its programmed value and shut down the trigger voltage when the water temperature
reaches the programmed holding value.
Dispensing System
The dispensing system consists of:
•
Dispense valve
•
Sprayhead
•
Funnel
The ITB brewer is a gravity dump brewing system. During the brew cycle the dispense valve will open allowing water
to flow from the tank to the sprayhead. The dispense solenoid is rated 120VAC but is rectified internally in the coil.
The sprayhead not only serves to diffuse the water over the product but also serves as the outlet flow control.
Tea brewing can be programmed with pulse brew routines.
The control board will open and close the dispense valve
multiple times during the brew cycle. Anytime a recipe is
set to a brew value of 86 ounces and higher will result in a
constant value pulse routine (:30/:15/:15). This will prevent
the possibility of the funnel from overflowing.
The tea brew funnel will have a small outlet restrictor to
facilitate hot water to have a longer contact time with the
tea (steeping) and a strainer screen to prevent tea leaves
from following to the server. You will have the option of
converting to quick brew by simply programming dilute
delay menu to OFF position and changing out funnel restrictor to a larger diameter opening.

Dilution System
The dilution system consists of:
•
Dilution valve
•
Flow regulator
•
Dilution nozzle
The ITB can be setup as standard or quick brew. The brewer will dump water directly into the tea server to dilute the
tea concentrate during the tea brew cycle. The dilution solenoid is a 120VAC valve mounted onto the same body
as the inlet solenoid. During a tea brew cycle, the dilution solenoid will open; water will flow through a .50GPM flow
control washer and out of the dilution nozzle.
