OPERATION
MAINTAINING PRODUCT QUALITY
It has been determined that the following factors can affect the rate at which product quality diminishes (as indi-
cated by a change in product appearance).
1. Dispensed Product Throughput
2. Programmed Defrost Scheduling
3. Viscosity Setting
Cornelius recommends the following instructions be read and followed relative to operating and establishing set-
tings for the FCB equipment. Cornelius equipment service manuals contain instructions on how to program set-
tings within the control system. Operators who have not been trained on servicing Cornelius FCB equipment
should not attempt to modify equipment settings but should contact an accredited service provider.
Cornelius makes the following recommendations to help assure maximum product quality.
Dispensed Product Throughput
FCB equipment is designed to provide a high throughput of frozen carbonated product to meet peak draw
demands. Where low product throughput is experienced, there is the potential for product quality to diminish. The
information shown in Table 34 outlines the minimum throughput per barrel that must be dispensed on a 24 hour
basis.
NOTE: Cornelius recommends that, in conditions where the FCB machine is operational and the minimum
throughput (as described in Table 34 is not met on a per barrel basis, product should be dispensed
and discarded to increase throughput and help assure that product quality is maintained.
NOTE: Data in Table 34 assumes equipment has been correctly installed, commissioned and calibrated as
per directions contained in all technical literature published by Cornelius and the recommenda-
tions contained in this document have been followed.
Cornelius recommends that, in conditions where the FCB machine is operational and the minimum throughput is
not met on a per barrel basis, product should be dispensed and discarded to increase throughput and help assure
that product quality is maintained.
Programmed Defrost Scheduling
The control system in the Viper system includes a function to automatically defrost product in the barrel at programmed
intervals based on the viscosity of the product. Programmed defrosts are scheduled frequently to ensure that product
quality within the barrel is maintained. Failure to defrost regularly during periods of low throughput allow increased ice
crystal size, with a possible decrease in product quality. Regular throughput of dispensed product replenishes the barrel
frequently with liquid and reduces the requirements for programmed defrosts. The unit automatically senses the lack of
throughput and maintains the product quality by defrosting the barrels more frequently when throughput is slow.
Sleep Mode Recommendations
Cornelius recommends programming a sleep period for the machine during any amount of time over 3 hours that
the unit is not used. This increases the life of the machine and reduces energy consumption.
A wake up time must be programmed after the sleep period to return the unit to normal operation. Cornelius recom-
mends programming the wake up time for approximately 20 minutes before the product is needed. This is the time
Table 34.
