  • The Wyma Absorbent Drying Rollers remove the excess surface moisture from produce. The main objective of this equipment is to reduce the risk of bacterial growth, disease initiation and produce degradation during storage, transport and packaging, and maximise shelf life. These non-desirable occurrences mostly effect fresh produce that are susceptible to wetting (produce can be harvested in the wet or sprayed, washed or dipped into a wet tank during processing).

    An Absorbent Drying Rollers module is mainly composed of rows of latex sponge or synthetic felt, with a small number of brush rows at the in-feed end and a row of pintle rollers at the out-feed end. Produce first lands on the brushes which provide a soft entry and flick off excess water. Drying Rollers (in sponge or in felt) then absorb excess moisture from the produce surface. Produce progresses forward with other produce pushing it. A row of pintle rollers ends the system to aid produce exit and to protect the last sponge rollers from damage. Underneath the drying roller bed, squeeze rollers provide pressure on the Drying Rollers to remove the retained water, optimising drying performance.

    Modules of 10 and 15 rows are offered. The modular built means that multiple modules can be added to meet the required amount of drying, and that there are no drops or transitions that may cause produce damage. The number of brush, sponge (or felt) and pintle rows can also be customised. The mix depends on produce wetness, the required amount of drying and operating conditions.

    The modular built also means that the Drying Rollers can be preceded with a modular Flat Bed Brusher for chemical application, for water spraying to wash-off extra dirt, or simply with additional rows of brushes to flick-off excess water depending on the wetness of the produce. A zero-drop transfer or reception conveyor can also be added to allow produce from other equipment to enter the line and by-pass other equipment that may precede the Drying Rollers.

    *Please note that this number of sponge or felt rows is customisable depending on required amount of drying, wetness and operating conditions.

    • Modular built for flexibility in functionality (possibility to add chemical application, brushing and spool sizing modules) and to match amount of drying required
    • Multiple widths to meet throughput requirements
    • Latex sponge or synthetic felt drying option
    • Squeeze rollers to apply a constant and adjustable pressure on the absorbent rollers to remove excess water, so that they are dried and fully absorbent when they touch the produce
    • Automatic wiper system to clear produce at the end of a run*
    • Water catchment tray to collect water (can be with/without water recycling system)*
    • Quiet, clean and low maintenance belt drive
    • Side removable shaft for easy maintenance
    • Bolted-on side removable panels for easy and quick access to internal structure
    • Squeeze rollers can be pneumatically operated to control timing of squeeze pressure, which maximises sponge life
