Automatic carrot topper WOA

The 3 or 4 lane automatic carrot topper WOA-3/4 consists of an infeed hopper with singulation system, a special conveyor, aligning belts and a knife platform. The conveyor is made of aluminium trays, which are mounted on heavy-duty drive belts on both sides of the machine. Mounted above the hopper is a unique driven levelling unit to ensure a single depth of carrots are delivered onto the stepped singulation elevator.

The singulation system positions the carrots in the trays. These trays then pass over the aligning belts, which are mounted on the underside of the machine. The aligning belts transport the carrots firstly to the left and then to the right, where they are topped or tailed depending on orientation.

The machine can be supplied with two type singulation systems:
Type S: carrot diameter 25 – 55 mm (1″- 2,16′)
Type L: carrot diameter 40 – 85 mm (1,57″ – 3,4″)

Depending on the execution of the machine, it is possible to cut the carrots into pre-set pieces of minimal 40 mm (1,57″) (standard 50 mm / 2″). These knives can optionally be executed in such a way that, by pushing a button, they automatically retract.

The machine is designed for easy maintenance and cleaning /sanitation and is equipped with threaded spindle motors which facilitates the lowering of the complete transport tray section in such a way as to give complete access to all internal aligning belts and cutting drive sections.

  • "The WOA-3 is ingeniously designed and of extremely robust construction, whereby only the very best quality materials have been used and totally reliable parts. The robust construction particularly appealed to us. We have to keep production going at all times and cannot afford to run the risk of lost time due to faulty machinery."

  • Mr. Daniel Verduyn, Verduyn NV,

Product specification

The WOA-3 processes carrots with a maximum length of 350 mm / 14” (min. 175 mm / 6,9”). The WOA-4 processes carrots with a maximum length of 250 mm / 9,8” (min. 125 mm / 5”). For a good working, the carrot foliage and stones have to be removed.
