Product InformationMega-Polisher
Washing & Polishing Equipment
Product OverviewWhat does a Mega-Polisher do? Washes and polishes fresh produce to highest retailing standards.
How does a Mega-Polisher work?Produce travels through a rotating barrel, made up of rotating brush shafts. Produce is washed/polished as it makes contact with the rotating brushes and as it rubs against other produce.
What produce types can be used? Carrots and other produce that needs a longer dwell time.When should you use a Mega-Polisher?
To clean produce to a high level, ready for retail shelves. To handle produce that needs a high level of polishing.

General Information (cont.)
Product Overview (cont.)
What is the difference between a Mega Polisher and a Vege-Polisher™?
A Mega Polisher is twice the length of a standard Vege-PolisherTM. It has all the proven features of the Vege-PolisherTM, but produce has more contact time with the brushes.
Where in a produce line, shoulda Mega Polisher be?
Place Mega Polisher before:
Drying or cooling equipment.Grading, sizing or inspection equipment.Bagging or other storage.
Place Mega Polisher after:
Wet Hopper, Hedgehog, Barrel Washer or other dirt removing equipment.Conveyors or flume delivery.
What other equipment might be needed:
Water Recycling System.The Mega-Polisher can be supplied as part of a ‘Mega-Polishing Solution’. The system includes: Mega-Polisher, Water Recycling Base, Rotary Screen Filter and an Outfeed Elevator. For more information, see the Mega-Polishing System Product Information Document.
Things that affectMega Polisherperformance:
Produce Condition and type of produce.
Machine
Amount of time produce spends travelling through the drum.Depth of produce in the machine.Speed of drum and brushes.Amount of water lubricating produce.
Where is water supplied from?
A combination of fresh and recycled water is often used. Fresh water is used at the outfeed end, to give produce a final fresh rinse. Recycled water is used at the infeed end and centre of the machine to minimise fresh water usage. Recycled water can be taken from a Water Recycling System (or another part of your line) or you can use only fresh water if you like.

How does it work?
Water spray bars:Lubricate produce and flush away dirt/debris.
Brush options:Wyma will recommend the best brush combination for you.
Brush speed:Increase speed for more aggressive scrubbing.
Drum speed:Increase speed formore agitation/mixing. Also reduces dwell time slightly.
Outfeed gate position determines the level of produce in the machine. Higher produce level means longer polishing time and greater scrubbing action.
Drum empty position.
Brush rinse bar:Sprays water on brushes to help keep them clean.
