Tray Washer - Off-line STW-2/3
Automated tray loading, washing, and conveying unit available in two or three-line tray infeed for destacking. This tray washing machine is optimized for off-line operation. Efficient, compact and labour-saving design.
The STW-2/3 Tray Washing machine is optimized for cleaning and drying up to 10,000 empty plastic trays/hour at top-class washing performance. This specific configuration is for off-line operation, which means it can be used as stand-alone equipment without being attached to an OptiLoader.
Dirty tray stacks are inserted to the tray-adjustable* destacker infeed and forwarded through the washing process. Up to 264 powerful high-pressure spray nozzles are waiting to clean your trays at around 5 bar, before they are automatically spin-dried and delivered back to you ready to be used again.

Installation Options
Safe de-stacking of dirty trays
The STW-2 and STW-3 is equipped with a new safe de-stacking system which ensures a continuous and safe production even with very dirty trays. The stack of dirty trays is secured by eight claws, while four claws force the bottom tray onto the conveyor. Furthermore, the discharge system is easily adjusted for different types of plastic trays. reducing operating costs.
Reducing operation costs
The SANOVO STW-2 and STW-3 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-2 and STW-3 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.
