Central CIP and Washing System
Central CIP is one of the rinsing systems that is mainly used for cleaning fluids based on food production lines and is designed with 3 to 4 washing steps and is installed in chemical and pharmaceutical production plants, and is made as manually, semi-automatic and full automatic. The washing process also depends on the food, pharmaceutical and chemical lines (liquids) associated with it and the more pollution in the production and processing lines causes different types of washing and solvents, but mainly some types of liquids that are used include: acid, hot water and sterilized water, and they can be designed in two types of reciprocating lines.
The CIP is based on the three words Cleaning in place, which means washing in place. The CIP system is a method of cleaning the interior surfaces of pipes, ducts, processing equipment, filters and fit
tings in the factories, without the need for manpower, hand involvement, and the separation of parts of the machine.
Various industries such as dairy, beverage, processed foods, pharmaceuticals and cosmetics re
quire a high level of health. The CIP system is a very important point. This method is quick and far more repetitive than other methods.
The steps normally performed in the CIP system (respectively):
- Use of high pressure water to eliminate the residual materials in the equipment
- Cleaning with alkaline materials that dissolve fat and proteins.
- Wash with water
- Cleaning with acidic substances that neutralize the remaining alkaline materials at the plant’s equipment level. It also eliminates mineral deposits (especially in devices like Pasteurizer)
- The final rinse used at this stage is cold water
Components that are commonly found in various CIP systems include water supply, measuring equipment, PLC controller, touch screen, dosing system, heat exchanger, input tank, exhaust tanks, spin-off valves, pressure and automatic valves, chemical pumps And process record graphs.
Advantages of the CIP system:
- No need for human resources
- Short process time
- Higher health conditions (the automated system works more efficiently than the manual system)
- High safety
CIP System Restrictions:
- Installation and commissioning should be done by experienced experts
- The flow rate or the pressure of the continuously used chemicals should be measured and monitored
Some applications of the CIP system
- Liquid fillers, especially in the dairy industry
- Meat baking systems
- Salad Production Systems
- Conveyors
- Meat sliders
