Each CIP programme when completed, is assigned an In-Site RECORD No. and is classified as either PASS, CAUTION or FAIL.

The RECORD No. is unique to each programme and is displayed on the front screen of the IN-SITE VIEWER. This RECORD No. appears on all reports relating to that clean, e.g. Graph, Cost Analysis, etc.

Each separate CIP operation generates a Verification Report (Due Diligence), this report providing evidence of compliance to procedures, permitting positive release of plant. Apart from giving peace of mind, it also provides high visibility in respect of Quality Assurance achievement to the site’s major customers.

Tolerance levels

The Verification report identifies the tolerance levels (minimum and maximum) set for each parameter and confirms what was actually achieved. If any of the tolerance levels are exceeded, the system will automatically identify the area(s) of failure.

The PASS/FAIL parameters can be set to be extremely stringent or less exacting forgiving, each site deciding their own tolerance levels.

The 1^st tolerance level triggers CAUTION, the 2^nd triggers FAIL. to demonstrate how the two tier tolerance system operates, if, for example, the required cleaning temperature is 70^OC, the 1^st tolerance level may be set a minimum temperature of 65^OC and a maximum of 75^OC. As long as the temperature range achieved is between 65-75^OC the cleaning stage/cycle is classified as PASS.

The 2^nd tolerance level may be set at a minimum temperature of 60^OC and a maximum of 80^OC. During the CIP stage where the temperature achieved is 60-65^OC or 75-80^OC, the classification will be CAUTION. Any CIP where the temperature is <60^OC or >80^OC will be classified as FAIL.

Stage Parameters

At each CIP stage, (max. 10 stages per CIP) a number of parameters can be set to compare what was actually achieved during each cleaning stage relative to the tolerance values set against that cycle.

The extent and scope of the In-Site Verification Report probably exceeds most automated CIP process controllers, in terms of information feed-back and reporting capabilities (MIS).

In-Site can monitor 10 separate analogues signals per clean selection. Each analogue signal 'value' is recorded in the Verification Report as 'average value' and 'maximum value'. In addition to analogue values, also monitored are benchmark values for Costs, CO2 emissions, Microbiological result and CIP duration.

It is most unlikely that all possible tolerance levels would be 'set up' in the Clean Parameters (per CIP selection) but with a total of 163 potential checks per CIP operation, In-Site's verification report is far more stringent than a site's CIP program philosophy would demand.

Archived Information

All data on CIP operations is automatically archived by In-Site, providing the site with accurate historical information on the performance of all their cleaning plant and enables frequently occurring faults to be clearly identified.

The Verification History can be filtered to show:-

(a) all Processes/CIP systems,

(b) a specific Process or CIP system/channel,

(c) a specific Process or CIP circuit - vessel or main.

(d) show only a specific Process or CIP cycle, e.g. detergent wash cycle, selectable as per a-c)

(e) show only a specific type of ‘failure’, e.g. low temperature, again selectable as per (a-c).
