BOHRER cleaning and drying technologies

The modular machine concept of the BOHRER container cleaning machines allows for individual equipment with optional accessories such as continuous filtration, CIP machine interior cleaning, vapour extraction, chemical dosing, container centrifugal or blower drying, etc. in addition to standard cleaning components.

We give the highest priority to the most extensive occupational safety during maintenance, cleaning and machine operation, starting with the design and automation software. For example, access from outside is not possible while the cleaning process is running. Intensive test runs at our factory and on-site operator training ensure the highest possible process and operator safety.

The heat-insulated container soaking tank with continuous hot caustic flow, automatic bath filtration and self-cleaning immersion floor is, in our experience, the best and most gentle solution for gentle crate soaking before thorough intensive cleaning.

In order to extend the lye service life and to make the machine cleaning as easy as possible, a patented continuously operating floor sludge emptying unit is installed in every immersion bath. 

After the pre-soak, stubborn dirt, labels, barcodes, price labels or stickers are safely removed from the inside and outside of the container by a special high-pressure unit with adjustable high-pressure spray nozzles.

The hand-adjustable patented clip spray nozzles distribute the spray water evenly from all sides and can be individually adjusted without tools to thoroughly clean compartments and dirt corners.

The permanent cleaning of the process lye from solid and suspended matter is carried out sustainably and in an environmentally friendly manner using high-tech stainless steel filters, even during automatic backwashing.

The innovative BOHRER centrifugal high-performance drying system works extremely quietly, with only approx. 2-3 g of container residual moisture (E1, E2 and E3 crates), and with up to 90% energy savings compared to conventional blower drying. 

Here we offer an integrated or external downstream retained water blow-off unit with frequency-controlled drive and high-performance blower with air nozzles that can be individually adjusted to the container.

Dirt in the immersion bath, such as labels, stickers and broken glass, is automatically removed from the machine by a cyclically running, durable plastic filter belt and can be disposed of manually or via a collection container (shard carriage).

In addition to cleanliness, the crate protection has top priority in the cleaning process. We use high-quality stainless steel slat chains for straight transport and upward turns with rubber-coated clamping jaws for multiple cleaning levels. 

Our special stainless steel transport path in our washing machines is specially designed for fast manual and automatic CIP cleaning with largely open side walls.

Depending on the degree of soiling, our modular machine system makes it possible to integrate an additional brush station for cleaning the sides of the crates on both sides to remove coarse dirt and stubborn labels and stickers.

Thanks to the clear BOHRER-typical interior design with a well-organised installation of pipes and transport equipment and helpful LED flood interior lighting, cleaning and servicing work can be carried out quickly, easily and safely.

For easy, fast and safe access to the interior of the machine for cleaning and maintenance, as well as for visual inspection of the cleaning process, our machines are equipped with large safety glass doors on both sides with access security devices. 

To make maintenance and repair work as easy as possible, all units such as pumps, motors, sensors and filters are installed in the machines in spacious technical rooms. Large, gas spring-supported swing doors allow easy access without reaching into the machine.

Extensive automation is one of our core competencies. Our patented, automatic CIP internal machine cleaning makes a significant contribution to this. Cleaning agents, pressure, temperature and cleaning time can be configured individually via the process control system of the machine.

To keep the humidity in the wet area of the plant as low as possible, we can install high-performance vapour fans on the machine inlet and outlet if required. The exhaust air piping is individually adapted to the local conditions.

Whether by phone or via remote service with access to your machine parameters – we are always there for you and offer quick help with technical questions as well as troubleshooting and repair. We optimise your machine parameters via our Quick Reality Support remote diagnosis service and, if necessary, provide you with the latest software updates.
