Medium Potato Line – Proven and robust
This 25-ton potato line has two receiving options. Produce may be received directly from a field harvest truck or via storage bins using an Electric Bin Tipper. Dry debris and soil are then removed by a Horizontal Debris Remover.
A Wet Hopper provides soaking, unloading buffer and an even feed to the line while a Flume Destoner, provides stone and clod separation. A Barrel Washer and Vege Polisher are used in combination to wash and polish the crop.
Water filtration is provided in the Water Recycling System and cleaner water is cascaded from the Polisher to Barrel, to Hopper to minimise water usage. Dirty water is treated in a Mud Separator ( not shown) to remove excess mud and soil from the water to allow recovery of soil before disposal.
After washing a Flat Bed Dryer is used to remove excess moisture with a Roller Inspection table used for manual quality inspection if required. Produced is then mechanically pre-sized by a Lift Roller Sizer to optimise the efficiency of the 3 Electronic graders next in line. These are fed with a small Evenflow Hopper for surge control.
The Lift Roller sizer will remove under and oversize produce for other use, and can be used for overflow of the main sizes should there be a mismatch of washed product vs Electronic grader capacity. Product is directed to Vertical Bin Fillers for this purpose with automated bin transportation for efficiency. Electric Bin Tippers with Takeaway conveyors are used in tandem for re-entering binned product as required.
After Electronic grading, product is directed to the Dry Bunker Storage area until required for packing.
A variety of weighing, packing and palletising options are showcased on this line. Produce is able to be sourced from each Dry Bunker and able to packed by one of the four packing lines. Seen here are options for Bagging/Palletising, Pouch Filling/Boxing, Bagging/Baling and Box Filling/Palletising. All are suitable options packing potatoes and would typically be configured to meet retail and consumer demand.

AS Wilcox & Sons
Known for producing some of New Zealand’s best potatoes, carrots and onions, the family-owned and operated company knows the value of robust and reliable post-harvest equipment. With lines running six days a week, 10 hours a day almost year-round, having the confidence in Wyma’s equipment is a huge plus for Wilcox.
“We spoke with Wyma about our requirements and the demands that we had, and found them very easy to work with, supportive and had a really good understanding of what our business dynamic was and what we needed,” says Mark Sade, Engineering Manager at A S Wilcox & Sons Ltd.
“The willingness to work with us as a supportive company to develop our own business dream was really attractive to us. They were willing to go that little bit extra.”
