The efficient separation of peel waste is an important objective for vegetable and root processors. TOMRA’s Dry Peel Separator or DPS provides you with a method to separate peel waste with zero water usage and minimal yield loss.

DPS - Dry Peel Separator

The DPS machine uses a specially designed stainless-steel drum with smooth perforated panels, which is tailored to your product. Inside the drum there is a mixing agitator that ensures the continuous mixing of potatoes and the transfer of the skin to the drum.


The drum rotates at high speed using an external drive shaft to enable the peel waste to flow to the dry-waste pump. Using this design TOMRA achieves a very high percentage of peel waste removal with less than 0.3 per cent loss of good flesh.

The latest design of DPS with mixing agitator provides you with significant improvements in terms of access for hygiene teams and many new features that reduce maintenance time. Using this design for certain applications you can avoid using a brush to remove the loose peel and also avoid losing valuable product.

The final result is a very high quality product without using any wash water!
