Maximize Floor Space & Pre-Wash Product

The Hydrolift Destoner continuously rinses and removes rocks and debris from “dirty” product while vertically lifting it to the core steps in your process, like washing and peeling. Its compact footprint and maximum discharge height of 28 feet allow you to take production to new heights.

Optimal Product Handling

The hopper and auger geometry positions product to lift into the auger with minimal damage or cuts.

Continuous Operation

A hopper baffle and water recirculation loop keep water and product running up the screw auger. Durable stainless steel ensures long equipment life.

Maintenance Friendly

A water-lubricating lower bearing keeps the auger running without maintenance downtime.

"We have a Vanmark Hydrolift Destoner as well as a competitor’s vertical auger. Vanmark’s runs like a dream. Its additional design features significantly help maintain product flow and uptime.”
