  • The Wyma Wet Hopper Destoner allows produce to be quickly tipped from a bin, truck or other device into a water-filled tank without fear of damage. It also removes stones and clods in the early stage of processing. Wet Hopper Destoners can receive produce in dirty, clean or semi-clean condition. It can be used with potatoes, carrots, parsnips, turnips, swedes and beetroot (beet) etc...

    Once into the Wet Hopper Destoner, fresh produce gently travels on a web conveyor belt towards an out-feed elevator. Fine sand and dirt are separated from the produce and fall through the web belt into collection hopper(s) in the base of the tank. The accumulated debris is periodically removed via the purge valves underneath (manual or automatic operation depending on option selected).

    An optional air agitation system is also available. The air bubbling to the surface agitates the vegetables causing them to gently rub against each other, helping to soften and remove the mud. It also helps to break up clumps of produce.

    The stone elevator discharges stones and clods on the side of the Wet Hopper Destoner where bins (or other loading item) can be placed. The stone removal system works by pumping water at a pre-determined flow rate up through a space between the base conveyor and the elevator. Due to inherent differences in density, produce simply float over the space, with the help of the upward water flow; whilst stones, rocks and dirt clods sink and are ejected from the Wet Hopper Destoner via the stone elevator. Stones and clods are removed on a continuous basis which makes the stone elevator a recommended feature for customers who have large quantities of stones and clods coming from the field.

    The produce is gently lifted out of the hopper via an elevator with gooseneck. The throughput of the line (t/hr) is determined by the elevator speed selected (5 options available) whereas the soaking time of produce in the water is determined by the actual holding capacity of the Wet Hopper Destoner. As the produce exits the Wet Hopper Destoner, additional spray bars can be fitted to provide a final rinse before moving on to other equipment in the processing line.

    The Wet Hopper Destoner adds five main benefits to a processing line:

    • It acts as a pre-soak and dirt/rubbish collection facility, ensuring that this material is not transferred to other equipment downstream.
    • It provide even flow delivery from intermittent supply.
    • It creates a temporary storage of produce that is waiting to be sent to the next part of the processing line.
    • It provides gentle handling of produce as the fresh produce is tipped into a water-filled tank.
