Keeping it clean - Efficient operation of hygiene sluices with Siemens logic module

Mohn is a market leader in the production of hygiene sluices, washing systems, and stainless-steel operating equipment for the food processing industry.

Bakeries, butchers, and chocolate factories all have one thing in common: Every employee must pass through a hygiene sluice before entering the manufacturing area. Employees may only leave the sluice once all the prescribed steps have been completed in order to avoid bringing germs or contaminants into the production area. Up to 5,000 cleaning cycles can therefore be quickly completed in a day depending on the size of the business. Mohn has developed the Highline workforce hygiene sluice for these cycles using a Siemens Logo! 8 logic module for the control function.

Depending on the size of the business, a single Logo! 8 unit can control up to 5,000 cleaning cycles a day.

Many benefits with opportunities to save

Mohn has focused on the energy and resource efficiency of the hygiene sluice as well as its overall efficiency. As a manufacturer, Mohn appreciates that Logo! 8 allows highly individual customer requirements to be accommodated and settings entered to the second. “We are the only company on the market that can do without detection sensors in optical form for shoe sole cleaning,” explains Carsten Homuth, Technical Project Manager at Mohn. This is one of the major benefits compared to circuit board control where the sensor only detects when someone enters the sluice. The brushes then run for a preset time interval – even if the employee leaves the sluice before the cycle is complete. However, with Logo! 8, the system immediately recognizes when the sluice is empty and stops the brushes as well as the addition of the cleaning agent which offers significant potential for savings.

Customers can retrieve consumption data from anywhere in the company via Ethernet and Mohn can also provide immediate remote maintenance support in the event of disruption.

New generation of Logo! 8

A further benefit of Logo! 8 is its many network interfaces. Customers can retrieve consumption data from anywhere in the company via Ethernet and Mohn can also provide immediate remote maintenance support in the event of disruption. It is therefore no surprise that Mohn has made this Siemens controller the control standard on all its systems and has further plans for it in the future. The new Logo! 8 generation, which has a programmable web server application, will have a part to play in this. This allows customers to set up their own control website using the Logo! web editor with access from a smart phone, tablet, or PC.

The precise control of the sluices and the actual duration of the programs they run provides Mohn’s customers with significant opportunities to reduce the consumption of both cleaning agents and energy.

A single Logo! 8 unit stops the brushes and the addition of cleaning agents as soon as the employee leaves the sluice.

Due to the many benefits Logo! 8 has to offer it is no surprise that Mohn has made this Siemens controller the control standard on all its systems.
