8.6. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may give
raise to skin burns.
Use rubber gloves during cleaning procedures.
Always use protective goggles.
8.6.1. Automatic CIP (clean-in-place)
If the blender is installed in a system with a CIP process, it is not necessary to disassemble the
blender.
If the automatic cleaning process is not provided, proceed to disassemble the blender as indicated
in the chapter
8.7. Disassembly and assembly of the blender.
ATTENTION
Check the concentration of the cleaning solutions. Incorrect concentrations may lead to
the deterioration of the blender seals.
To remove any traces of cleaning products ALWAYS perform a final rinse with clean water at the end
of the cleaning process.
Two types of solutions can be used for CIP processes:
a. alkaline solution
: 1% by weight of caustic soda (NaOH) a 70ºC (150ºF). To make this solution:
1 kg NaOH + 100 l H
2
O
1
= cleaning solution
2,2 l NaOH 33% + 100 l H
2
O = cleaning solution
b. acid solution
: 0,5% by weight of nitric acid (HNO
3
) a 70ºC (150ºF). To make this solution:
0,7 l HNO
3
53% + 100 l H
2
O = cleaning solution
1)
only use chlorine-free water to mix with the cleaning agents
8.6.2. Automatic SIP (sterilization-in-place)
The steam sterilisation process is applied to all equipment including the blender.
Do NOT operate the equipment during the steam sterilisation process.
The parts and the materials will not suffer damage provided the instructions set out in
this manual are followed.
Cold liquid cannot be introduced until the blender temperature is below 60ºC (140ºF).
The blender generates a substantial pressure loss through the sterilisation process. We
recommend the use of a bypass circuit provided with a discharge valve to ensure that the
steam or overheated water sterilises the entire circuit.
Maximum conditions during the steam or overheated water SIP process:
a. maximum temperature: 140ºC / 284ºF
b. maximum time:
30 min
c. cooling:
sterile air or inter gas
d.
materials:
EPDM (the materials HNBR y FPM are not recommended)
