The purpose of the POLSAP Waterunloader is to gently unload floating and nonfloating fruits such as apples and pears from storage bins so it can be feed into a pregrading system or a repacking station.  The product is unloaded in the dump tank by an integrated bin lift that clamps the full bin and gently submerges it in the dump tank. The fruits float out of the bin and is taken along with the water current to the buffer channel.

Beside unloading bins, the system is also used to transport, manipulate, (un)stack and unload bins with fruits and agricultural products.
Based on the configuration of the system a wide array of movements and actions can be performed such as bin rotation over multiple axis, stacking and nesting of bins. Product unloading and dosing can be done in combination with unloading systems from Burg to unload the product in a manner that best fits the respective product. POLS system can also be used to transport bins to other devices such as bin washers and to other locations in the production facility.

Optional functionality can be added to a POLS system for applications such as dry dosed unloading of more sturdy products and the nesting of bins (POLS-KD, POLS-KO & POLS-KN).
