CIP full form


CIP full form is CLEAN IN PLACE. Cleaning in place, or CIP is a method of sanitizing processing equipment without the need for disassembly. The process uses steam, detergents, and other cleaning chemicals to clean the equipment. CIP systems can be manual or automated.

What is CIP and what does it stand for?

CIP stands for Clean In Place. It is a method of sanitization used for a piece of processing equipment without the need for disassembly. This method uses steam, detergents, and other chemicals to clean the equipment.

How does CIP work?

The cleaning solution cleaner is injected into the processing equipment through a port or headers on the outside of the machine or additional ports that are located throughout the interior of the system.

The solution then circulates around by means of pumps, mixers, rotators, and/or baffles to ensure that all surfaces inside are completely covered.

After circulating around inside, it then flows into a drain port from which it can be discharged from either opening directly to sewer or first passing through a grease and solids filter to remove any solid contaminants. CIP systems can be manual or automated.

The benefits of CIP

CIP is an effective way of cleaning processing equipment that is continuously in operation (CIP stands for Clean In Place). It does not require the equipment to be shut down, which reduces downtime and cost of production thereby increasing plant efficiency and productivity.

Consequently, this method enables sanitation without dismantling the equipment which saves time and money as well as eliminates disassembly-related injuries like cuts and bruises from sharp objects.

Since there is no interruption of the process line, it helps reduce product loss due to contamination by microorganisms such as bacteria, mold spores, and yeast – all of which can adversely affect product quality. Since no manual labor is necessary, it saves costs by reducing the number of man-hours.

CIP also reduces water usage and waste production since a single batch can last up to 20 cycles which means that fewer detergents are required. It also helps to reduce energy consumption by utilizing less hot water for cleaning.

Another added benefit is that it enhances worker safety by ridding potentially hazardous tools from being handled manually because there is no need to dismantle the equipment for cleaning purposes.

Manual vs automated CIP systems

There are two types of CIP systems namely, manual and automated CIP systems:

Manual CIP systems entail the use of valves, pumps, and lines operated and controlled by hand. On the other hand, automated CIP systems involve valves and pumps that are operated and regulated electronically.

Types of detergents used in CIP

The chemicals involved in a CIP system can include an alkaline chemical such as caustic soda (NaOH), sodium carbonate (Na2CO3), or ammonium hydroxide (NH4OH).

Other chemical components may include acids such as phosphoric acid (H3PO4), hydrochloric acid (HCl), nitric acid (HNO3), or acetic acid(CH3COOH). Detergents with surfactants are also commonly used.

Some examples of these are linear alkylbenzene sulfonates, alkylphenol ethoxylated, and alcohol ethoxylates. CIP systems can also use other chemicals such as oxidizing agents like hydrogen peroxide (H2O2) and chlorine or chlorinated water to sanitize equipment

How does a CIP system work?

For an automated process, the various valves in the system are opened by means of sensors that detect whether the lines running through the machine are “clean” or not so that they can direct flow to corresponding places.

Sensors may be located inside boilers where they monitor temperature and material balance. Other types of sensors include sight glasses, pressure sensors, and level electronics.

PLCs automatically control operations while SCADA (supervisory control and data acquisition) provides a connection between the CIP system and the plant’s operating systems such as production, safety, and information management.

With manual CIP systems, valves are opened and closed by people using manual controls. This makes it easier to handle several pieces of equipment that need cleaning simultaneously since each piece requires monitoring.

The main drawback with this method is that more manpower is required which leads to increased costs due to the employment of more staff plus downtime while machines are being cleaned.

How does one clean a CIP system?

To sanitize surfaces in a food processing plant, chemicals such as caustic soda or sodium hydroxide mixed with water can be used on hard surfaces such as floors and walls.

In addition, chlorine may also be used to control microorganisms such as bacteria, mold spores, and yeast which can cause contamination of the products in the facility.

On the other hand, when sanitizing equipment like tanks, hot water mixed with chemicals or detergents is typically used together with compressed air jets to remove deposits that cling to inside surfaces.

Afterward, parts are rinsed thoroughly with clean water for several cycles before they dry completely.

How does one maintain a CIP system?

CIP systems need routine maintenance for optimal performance which entails calibrating equipment like valves to ensure efficient operation. Valves should be calibrated in order to reduce the risk of damage due to fluctuations in pressure while operating.

There are also regular cleaning procedures that should be done to ensure optimal sanitation in processing areas. This is usually done in conjunction with scheduled maintenance so that service technicians can replace worn parts and components which have reached the end of their useful life.

How does one know when a CIP system needs repairs?

Leaks in valves or check-valves indicate wear and may lead to contamination of products if untreated. Temperature fluctuations may cause showering or fog in pipes, fittings, or filters which will interfere with the CIP process because chemicals used are unable to leave deposits at these locations.

With manual systems, chemical residuals might be left inside lines when they are not completely drained after shutdown periods.

This happens when there is no automatic disconnection of equipment inside the plant during periods when machinery is not operating, leaving a supply of chemicals in lines that will be pumped into them again upon startup.
