  • The Wyma Wet Hopper allows produce to be quickly tipped from a bin, truck or other device into a water-filled tank without fear of damage. Wet hoppers 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, fresh produce gently travels on a web conveyor belt towards an out-feed elevator. While in the Wet Hopper, 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 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. As the produce exits the Wet Hopper, additional spray bars can be fitted to provide a final rinse before moving on to other equipment in the processing line.

    The Wet Hopper adds four 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 the 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.
