Tray Washer - In-line STW-12/18
Automated tray loading, washing, and conveying unit available in two or three-line tray infeed for destacking. This tray washer model is optimized for in-line operation with the OptiLoader Plus 12 and 18. Efficient, compact and labour-saving design.
The STW-12/18 Tray Washer is optimized for cleaning and drying up to 7,200 trays/hour. This specific configuration is for in-line operation to work in synch with the loader models OptiLoader Plus 12 and 18.
Due to the integration with the OptiLoader, egg trays are washed just after they are being emptied without prior stacking. An automatic stuck-egg conveyor ensures that no stuck egg is sent to the washing section. Overall, the integration saves an entire work process and only one operator is required to control the operation.
During the washing, up to 264 powerful high-pressure spray nozzles are cleaning your trays at around 5 bar. After that, they are automatically transferred into the spin-dryer, which safely returns the dry stacks back to you ready to be used again.
- STW-12: Up to 5,000 trays/hour
- STW-18: Up to 7,200 trays/hour
- Risk reduction through an automatic stuck-egg conveyor
- Efficient washing by high-pressure power nozzles
- Energy cost savings through re-use of water through collection tanks
- Low spray nozzle maintenance through an in-line filter
- Fully automated cleaning and drying of trays

Installation Options
Reducing operation costs
The SANOVO STW-12/18 has been designed with the primary goal in mind – to reduce operating costs by substantial cuts in the manpower needed. Including high capacity, top-class washing performance and low energy costs - the payback time of the tray washer is short.
Washing with power nozzles
In the wash chamber, power nozzles are placed closely above and underneath the trays. By spraying a large volume of pressurised water, the dirt on the trays is simply blasted off. No dirt will remain on the trays after the power nozzles have done their work. The water is filtered and recycled to minimise the use of fresh water. After washing, the trays can be disinfected by a sanitiser spray bar.
Dry trays improve hygiene
The spinner has a speed of 840 rpm, leaving the trays absolutely dry and ready for use.
Performance Monitoring
The entire washing operation is easily controlled from a touch display. Parameters such as speed, spinning time, etc., may be changed simply by pressing one of the pictograms and entering the desired value.
During production, the performance, as well as speed, run time, down time, number of trays washed, spinning time, error codes etc., is continuously shown on the display. SANOVO STW-12/18 is equipped with two local operator panels on the washer and one local operator panel on the spinner for start/stop, reset and emergency stop.
