2.13.2 ASEPTIC EXECUTION
Whenever a sterile plant and product needs to be ensured, an aseptic version
of the NIRO-SOAVI machine is available.
This can be achieved by running sterile condensate through the plungers in the
seal section and through the seal of the homogenizing valve shaft using
appropriate sterile chambers to avoid contamination from outside sources.
Condensate is produced by steam condensation at a temperature of
approximately 140 to 150C through water run in a heat exchanger.
The cooling water should be clean and preferably softened to avoid scaling
deposits in the exchanger.
Water hardness must be under 8 °dH / 15 °fH, with recommended chloride
value < 25 mg/liter and in no case greater than 200 mg/liter.
The required flow rate and water temperature values are indicated in the
consumption tables, Section 1 – TECHNICAL SPECIFICATIONS.
