Syrup Delivery Path
The peristaltic pumps control the delivery of flavored syrup for a drink.
The tubes for flavored syrups are smaller than the tube for chocolate
sauce.
Flavored syrup flows from the flavor box, through the syrup tube and into
the syrup manifold to mix with the milk flow. Once the flow of syrup ends,
the poppet valve closes. Milk continues to flow into the syrup manifold,
once the syrup poppet valve closes to rinse the syrup manifold of
residual syrup and then steam is flushed through the syrup manifold, to
clear the manifold of residual milk.
At the end of a syrup-based drink pour, a small amount of steam is
flushed through the syrup manifold.
Flavor Tubes
There is a dedicated flavor tube for each flavor. Each flavor tube is color-
coded for ease of use and to prevent cross-contamination of flavors.
Each flavor tube begins at the flavor box, goes through the peristaltic
pump assembly, and then to the syrup manifold. To reach the syrup
manifold, the flavor tubes are routed through the back of the machine.
The color coding of the flavor tubes is listed below.
