Three types of cleaning process

3.Automated
Automated cleaning typically does not involve personnel intervention. The system is usually
programmable for the various cleaning cycles.

These types of cleaning systems provide consistent cleaning due to the automation of the process.
Critical cleaning parameters for automated cleaning may include the volume of cleaning
agents, volume of rinse water, flow rates and temperature of wash and rinse solutions,
duration of wash and rinse cycles, pressure of solution, operating ranges and detergent
concentration.

Disassembly of equipment may still be necessary to allow for complete
cleaning or to allow for the separate cleaning of delicate parts.
In an automated cleaning system, the cleaning may be controlled through relay logic, a
computer or PLC (Programmable Logic Controller).

The control system is an integral and critical part of the overall cleaning process. The control system regulates the cleaning cycles,
addition of cleaning agents, temperature, time and other critical cleaning parameters.
There may also be a control interface or operator interface to start the process, stop the
process, monitor various stages of the process and change the process sequence. Given the
increased complexity of the newer PLC and computer interfaces, training and validation are
important issues that impact the ability of the system to provide consistent cleaning. The
validation of control systems and the change control policies which govern them are critical
to the success of the cleaning process
