Equipment
Washers, destoners and feeding equipment
Cyclonic stone trap
Product is carried in water through a cyclone that drops stones and sand out of the flow. Used at the front of root crop and potato lines ahead of the washer.
Universal flotation washer
A water tank with impellers and air agitation that moves product through the bath. Floating debris is skimmed and heavy debris settles. For fruit, vegetables and leafy products.
Multi-jet vortex washer
A two-stage vortex washer with an insect and snail trap and a dewatering transfer, used in fresh-cut and leafy green lines.
Details →Bubble washer
Air bubbles and adjustable water flow lift dirt off delicate products such as lettuce, spinach and herbs without bruising.
Brush and spray washers
Rotating brushes with spray bars for firm products that need surface scrubbing, such as carrots, sweet potatoes and cucumbers.
Tomato reception & flume washing
Truck unloading into water flumes, stone and sand removal and a water re-circulation system, built for mechanically harvested tomatoes.
Details →Bin and pallet box dumpers
Automatic bin dumping lines and lift-and-dump pallet box dumpers feed the washer without dropping product from height.
Food transfer pumps
Cast stainless steel pumps move product in water between washers, peelers and cutters, replacing mechanical conveyors where water handling makes sense.
Details →Where washing sits in the line
Clean, stone-free product protects the peeler, the cutter knives and the pumps downstream. On potato and root crop lines the washer and destoner are usually followed by a steam peeler; on fresh-cut lines by coring, slicing and drying.
Washing questions
Which washer is right for my product?
It depends on how dirty the product arrives, how firm it is and what comes next. Root crops usually need a drum washer and stone removal; leafy greens and fruit need gentle flotation, bubble or vortex washing. We recommend the combination after we know your product and line.
Can the wash water be re-used?
Yes. Bigtem designs re-circulation with screens, settling and filtration so most water is re-used, which is standard on tomato reception and root crop lines.
Do you supply the feeding equipment too?
Yes. Bin dumpers, pallet box dumpers, accumulation hoppers and even-feeding conveyors are part of the scope, so the washer always sees a steady flow.
Can a washer be added to an existing line?
Yes. Washers and destoners are sold as stand-alone modules and fitted to your conveyors, utilities and floor space.
