PROJECT
INCORPORATING COLD CHAIN
He quantifies, “The existing plant,
before any of our modifications, had
a cooling capacity of 161kWR, with a
power draw of 191 amps and batch
cooled the berries in three to four
hours. The new plant with a cooling
capacity of 250kWR, has a current
draw of 215 amps and batch cools the
berries in one to two hours.”
Effectively this means an increase
of at least 50% in production nominal
capacity with an increase of only
10% in power usage. When the
second phase of the modifications
are done, the increase in production
and with a better quality product
because of a more effective chill
chain, will be greater.
