Reza Hygiene

Hygiene System Center supplies water, diluted detergent and diluted sanitiser to a distributed ring main typically used for the disinfecting and cleaning of filling machines used in the food processing industries.


The Challenge:
Having worked previously with Reza Hygiene they approached us to develop a PLC controlled centralised hygiene center which will deliver detergent, sanitizer and rinse water for washing applications in food or dairy factories in Saudi Arabia.
The system should be capable of pumping each solution at a preset pressure set point to remote hygiene stations around the factory. The detergent and sanitizer solutions are automatically diluted from remote bulk chemical drums.

The Solution:
In partnership with Reza Hygiene, Simonswood provided a custom built stainless steel enclosure with an Allen Bradley Micrologix 1400 PLC, with five Powerflex M Variable Speed Drives along with an Allen Bradley 6 inch Colour Touch Screen Panelview Compact as an operator interface.
Each Solution Tank’s Level and Line Pressures are monitored by 6 Endress & Hauser pressure transducers. The Chemical dilution is controlled via 2 ProMinent motor driven metering pumps.The system was built and thoroughly tested prior to being shipped from the UK to achieve a plug and play operation at the clients’ factory in Saudi Arabia.

The Result:
The System enables the end user to switch on and leave it, with the only user intervention being to change the bulk chemical drums. The end user will be safe in the knowledge that the washing solution pressure and strength will always be as required.
