What is CIP ?
|
|
CIP or in its full form, Cleaning In Place, is defined as a
method of cleaning equipment with minimal dismantling and
with minimal operator involvement.

|
What are
the benefits of CIP? |
-
Validateable Procedures
-
Reproducible, Repeatable and Controllable Results
-
Reduction of Cleaning Time
-
Automatic cycles ensure every item is cleaned every time
-
Increased productivity through reduction of down time
-
Chemical Handling Reduction
-
Simple Operation
-
Cost Savings including chemicals, water and effluent,
labour time etc.
-
Improved Health and Safety
-
Batch Traceability and Records
-
Stronger Chemicals and higher temperatures can be used
over manual cleaning
-
CIP allows more complex processing systems to be
employed, as there is no need to dismantle
-
Environmental Issues including saving of energy,
chemicals, water used and effluent generated.

How does CIP
work? |
|
CIP relies on the principal of applying a suitable detergent
or solvent at a suitable flow, pressure, temperature and
concentration for the correct length of time. The science is
based on applying the required amount of energy to the
equipment to ensure that it is cleaned. The energy is
primarily provided by the solution temperature (thermal
energy), the use of detergent or solvent (chemical energy)
and the application of suitable pipeline velocities or
pressures (kinetic energy).

|
What is the
Result of CIP? |
|
In-place cleaning results in the equipment being chemically
clean. This is defined as "the removal of all residues
of soil and all CIP agents so that contact with the cleaned
surface does not result in physical contamination". If the
equipment being cleaned needs to be micro-biologically clean
then an additional process can be carried out. This process
is called SIP.

|
What is SIP ?
|
|
SIP or in its full form, Sterilising In Place is the generic
term for sanitizing, disinfecting or sterilizing equipment
normally after a CIP clean. SIP results in the removal
of any remaining microbiological contamination.
|

| |
|
What is Chemical SIP? |
|
Sanitation or Disinfection is normally applied after the
full CIP has been carried out. It is achieved by the
introduction of a sanitiser or disinfectant chemical into
the final rinse waters of the CIP. |
| back to top |
| |
|
What is Thermal SIP? |
|
Thermal sterilisation is achieved by the application of
steam or hot water at a suitable temperature for a suitable
time. Thermal Sterilisation has the advantage of affecting
areas such as sample points, which may not be treated by
chemical means. |

|
Wash In Place (WIP) - What is this?
|
|
There is no legislative distinction between Clean In Place
(CIP) and Wash In Place (WIP), however the general industry
view on the terminology is that CIP means a totally
automatic cleaning sequence with no manual involvement,
whereas as WIP includes some manual intervention. In
practical terms CIP requires high levels of validation,
against WIP which requires less stringent validation.

| Hygienic Processing
FAQ |
| |
| |
|
What is
Hygienic Processing? |
|
Hygienic processing is processing using suitable materials,
designs and techniques to retain the hygiene quality of the
products whilst processing them and not to impart any
impurities whilst processing. Hygienic processing starts
from a clean system, carries out the processing and is then
cleaned ready for the next process.

|
What is BSL? |
|
Biocontainment can be classified by the relative danger
to the surrounding environment as biological safety levels
(BSL). There are four safety levels, BSL1 to BSL4, with
higher numbers indicating a greater risk to the external
environment.

| |
|
What is
Passivation?
Passivation is a method of maximizing the inherent
corrosion resistance of the stainless alloy. It remains a
critical step in maximizing the essential corrosion
resistance of stainless steels. It can make the difference
between satisfactory performance and premature failure.
However, incorrectly performed, passivation can also
actually induce corrosion.

|
What are
Hygienic Fittings? |
|
Hygienic Tubes and Fittings are specifically designed for
applications where there is a requirement for the internal
surfaces of the pipes to be cleanable. They are produced
with internal surfaces which are smooth and do not have
obstructions or crevices that could capture the product and
subsequently cause contamination. These requirements are
typically present in the food processing, dairy, brewing,
pharmaceutical and many other hygiene critical industries.
They are also often used as an economic stainless steel
piping system in many other industries.

|
What types of Hygienic Fitting are there? |
|
In the UK and Ireland there are a number of different types
of hygienic fittings used. These include the fittings
identified in British Standard BS4825 Parts 2 to 5.
(EN20286) which covers RJT, IDF and clamp fittings. There
are other British hygienic unions that are used occasionally
including SRJT (similar to RJT but for larger sizes) and ILC
(a union developed for CIP purposes).
Other American and European hygienic standards are also
sometimes used. These include DIN 11850 to 11852, US 3A, SMS
and
DS.

|
What hygienic Tubes should we use? |
|
ASTM A 249, A 269 and A270 are the most commonly used
manufacturing standards for hygienic tubes. The tube is
provided with the internal weld bead removed or flattened.
The internal finish and external finish can be specified (as
seen, for example, in the ASME BPE standards).

What is a Tank? What is
a Vessel? |
|
A Tank is defined as "a
large container (vessel) for holding gases or liquids at
atmospheric pressure". Tanks are available in rectangular,
cuboid or cyclindrical shapes.
A Vessel is defined as "a closed
container designed to hold gases or liquids at a pressure
different from the ambient pressure". Vessels are normally
vertical or horizontal cylindrical shape.
