CIP Systems

The sanitary aspects of producing food and beverage products are of extreme importance. Plants must meet high hygienic standards to avoid product’s degradation and contamination during operation, and plant cleaning must be carried out quickly and thoroughly. The cleaning requirements are best met with Cleaning-in-Place (CIP) systems. CIP systems offer fast, efficient and reliable cleaning of all types of process plant. It’s a method which cleans complete items of plant equipment or pipelines circuits without dismantling the equipment.


  • Reproducible, repeatable, can be validated and control operation
  • Simple and minimum manual intervention operation
  • Batch traceability and parameters recording


  • Reducing cleaning cycle times
  • Improved cleaning
  • Uniformity in cleaning
  • Optimization of the use of chemicals (acid, caustic etc.) and water


  • Personal & Home Care which include Creams, Lotions, Shampoos, Toothpaste etc.
  • Food & Beverages which include jams, ketchups, sauces, soft drinks etc.
  • Dairy Industry

Factors Affecting CIP

  • Type of soil
  • Type of Process equipments
  • Time of CIP
  • Concentration of CIP solution
  • Temperature of CIP solution
  • Water Quality
    -Chemical properties (pH, hardness etc.)
    -Biological properties (bio-burden, end toxins etc.)
  • Type of CIP system
  • Process System Clean ability and drain ability
  • Dead Legs in Process systems

Step 1: Flushing in order to eliminate residues

Step 2: Alkaline cleaning operation: alkaline detergents dissolve fat and proteins, and cleaning where harder deposits have occurred

Step 3: Intermediate water rinse

Step4: Acidic cleaning operation: for neutralizing the caustic remaining on the surfaces of the plant. The acidic detergents remove mineral deposits in the equipment (especially warm areas like in the pasteurizer)

Step 5: Final water rinse: Cold/hot water purges out the residual acid solution CIP is a closed system where recirculating cleaning solution is applied (often with nozzles) that cleans, rinses and sanitizes the equipment.

The CIP system is usually automatically controlled and the cleaning sequences are given the optimum timing for efficient cleaning of all parts of the plants.
