OPERATION
AUTO BAG SELECTORS
These are used on higher volume B-I-B systems where two or more bags of the same product are connected to one
pump and one system. An auto bag selector is essentially a valve that automatically changes from one bag (or series
of bags) to another bag (or series of bags) of syrup as the bags empty, allowing a constant flow of product.
B-I-B
The Bag-In-Box system refers to a plastic disposable bag. The B-I-B normally contains 5 gallons of syrup, however
some locations offer 2 1/2 or 3 gallon B-I-B units. This plastic bag is then held inside a cardboard or other container.
PUMPS
The syrup in a B-I-B system is delivered to the beverage system through gas operated pumps. These pumps
extract the syrup out of the bags forcing the syrup throughout the system.
RACKING
Regardless if you are working on pre-mix or post-mix (B-I-B or Figal) system, a place will be designated for placement
of the product. A rack (or shelf) system affords systematic placement and complete usage of the beverage paid for.
The B-I-B rack allows the boxes to lay properly for syrup dispersal. Please check with your B-I-B syrup supplier. Some
boxes must be slightly tilted down, while others may be in virtually any position. The Figal tank rack keeps the newer
and full tanks organized at one end of the beverage line with the partial tanks at the other.
PRE-MIX & POST-MIX BEVERAGE DISPENSERS
Pre-Mix - Only a small number of systems use Pre-Mix,
usually for temporary or very low volume dispensing where
installation of a carbonator is not warranted.
Pre-Mix means that syrup and carbonated water are al-
ready mixed at the bottling plant, then chilled at the dis-
penser location before being served.
A memory peg for the meaning of Pre-Mix is that the
syrup and carbonated water are mixed together before
leaving the beverage valve.
Post-Mix - Most beverage systems are Post-Mix. Per-
manent dispensing locations with a mid to high volume
dispensing have Post-Mix systems, such as self-ser-
vice dispensers in Convenience Stores, Restaurants
and Cafeterias.
Post-Mix means that syrup and carbonated water (or plain
tap water for non-carbonated drinks) are mixed together
in the valve nozzle of the dispenser, just before the fin-
ished beverage flows into the customer’s cup.
A memory peg for the meaning of Post-Mix is that the syrup
and water are mixed after leaving the beverage valve.
The two common Post-Mix systems are:
1. Bag-in-Box (BIB) - Most often, five gallons of
syrup is stored in a plastic bag inside a carton.
2. Figal - Most often, five gallons of syrup is stored
in a stainless steel canister.
