WARNING !
In case the machine or part of product circuit, have been disassembled,
before starting CIP operations, make sure that all parts have been
correctly tightened.
DANGER !
During cleaning and sanitizing front door and pumps surfaces can reach
high temperatures (over 65°C) and cause severe burns if contacted.
To avoid the risk, during these operations, personnel must keep away
from these parts of the machine (no manual intervention is necessary
during cleaning and sanitizing).
WARNING !
Rotary pump type FAR : If the rotary pump is not equipped with the by-

sanitizing solution must never exceed 82°C.
10.3.2. PRE-RINSE
The purpose of this step is to flush out as much of the soil (residual
product) as possible and minimize the soil which must be chemically
removed in the following steps.
If the product contains fats, the temperature should be above the fat
melting point. If the product contains protein, too high temperature can
“set” the protein making them more difficult to remove.
Generally, temperatures between 50-60°C are best.
Continue to rinse, discharging to drain, until the rinse water becomes
clear.
10.3.3. SOLUTION WASH
The purpose of this step is to chemically and mechanically remove the
soil in the system. Caustic cleaning chemicals are best for most types of
soil (residual product) .
Concentration of caustic cleaning solutions is typically 2%
causticity.
Circulate the cleaning chemical solution for 30 minutes.
temperature ∼ 75°C.
