CIP / SIP Process efficiency (Cleaning/Sterilization in place)

Cleaning and/or sterilization in place processes (CIP or SIP) are a priority in food production as well as in health products. Efficient operation of these systems ensures the compliance of cleaning norms and machinery usage time and production processes.

CIP / SIP Automated system

Operating automation on a CIP system guarantees strict compliance with cleaning standards thus having important savings in energy consumption and chemical products; likewise operating time of this process is optimized allowing an increase in production machinery availability.

CIP / SIP process automation benefits:
Thermal energy saving
Cleaning agents re-use
Time optimization in the CIP / SIP operation
Production line availability increase
Minimize raw material or product waste by contamination due to mishandling

CIP / SIP Process description:

Phase one:

Clean water is pushed through in order to eject all product from the line to be cleaned

Phase two:

Rinse with retrieved water is done, this water is a water + soda solution obtained from the posterior rinsing of the recirculation phase with soda; this allows us to make a first cleaning with a stronger solution than water and saves water and soda.

Phase three:

A recirculation of water and soda is done with a concentration of 2-4% during the set time.

Phase four:

Rinsing with network water is done, gathered from the retrieved water deposit and that will help us in the first rinse of the next cleaning.

Phase five:

Only in case of using steam (SIP) or some sterilization agent.

Measurement and control elements

In order to guarantee a complete cleaning, four combining factors must be taken into account: mechanical action, chemical action, temperature and time. These four elements make up the so-called Sinner circle and can be monitored through instrumentation and control.
