The Lipton Iced Tea Brewer (LBIT) looks and operates like a leaf tea brewer. The LBIT
instantaneously mixes and dispenses tea extract, hot water, cold water, and liquid sweet-
ener to provide a finished tea product. Unlike leaf tea brewers, the LBIT does not have
high maintenance and operational costs, and it is not as susceptible to the bacterial growth
inherent to leaf tea brewers.

PERATION
The fresh brewed process involves the mixing of concentrated (100:1) tea extract with hot
water in order to brew the tea. A residence time of about 0.50 seconds ensures that the tea
mixture is adequately dispersed and increases clarity.
A metered quantity of cold water is added to the brewed tea mixture to produce finished
tea. The cold water reduces the temperature of the final product to approximately 90° F
(32° C). This temperature is similar to iced tea product dispensed from leaf tea brewers.
