CIP (Cleaning In Place) with recirculation process

Reference: B.4.1

LEME Adaptation

The CIP is an automic system for installation cleaning without proceeding to dismantling all the equipment

Industrial Use: beverage industry, agrofood industries, diary product activities

Decrease of water consumption by 70% in relation with cleaning processes and chemical reagent consumption by at least 40%, from return of experiences (technical littérature) when recirculation configuration is implemented

CIP processes and Green CIP approaches are well described in the technical documentation and on specialised web sites with case-studies. Green CIP is focusing on chemical recycling as well as high water consumption reduction rates.

Estimated pay back time short term : 2-4 years, medium term: 4-6 years, long term : 6-8 years (*)

Medium term with typical return of investment of 4-5 years

“Two main configurations :
– Simple configuration : New cleaning solution is introduced into the system and then circulated in a drainsystem for cleaning the production facility (in place).. In most cases, the procedure is as follows : a single pass system would start with a pre-rinse, then the detergent clean and a final rinse would follow these first operations (multi-phases).
– Recirculation configuration : The cleaning solution is introduced in an external tank (process vessel) and circulated in a drain system. Then introduced in the system to be cleaned. It is recirculated and topped up as many time required until the cleaning cycle is complete. When the detergent cleaning is complete a final rinse is carried out. Recirculation systems use less water and cleaning detergents but require greater capital costs. The cleaning solution is some cases, can be reuse for another cleaning procedure.

The CIP system is composed of the following equipments (no exhaustive list) :
– tank
– pump
– pipe
– instrumentation equipment “
