Havatec debulber: a new debulbing method

The new Havatec debulber is characterised by the fact that the running parts are easy to reach, making it possible to clean them properly. Rotating the debulbing technology out of the product flow is possible, without settings getting lost. The new debulbing method ensures virtually no stem breakage. The stem can no longer become stuck and will no longer miss jacks or torpedos. The material selection is adjusted to water forcing (stainless steel and plastic).

Benefits of the Havatec debulber:

  • Very easy to adjust
  • Changes in bulb size are simple
  • Low maintenance costs
  • High capacity
  • No stem breakage
  • Capacity is always higher than the bunching machine capacities
  • Suitable for Quality Buncher, TulipStar and Furora
  • Additional option: The T-Star Synchro Unit for the benefit of the Quality Buncher
  • Easy to clean
  • Resistant to the acidity of plants by means of durable materials such as stainless steel and plastic

Parts

Collection belt

This belt consists of a flat running section by means of which the tulips are brought to the height of the string unit. The belt consists of 2 strips, whereby the bulbs of the tulips should be on the narrow strip and the remainder of the tulips on the wide strip. The twist string is located between these strips (see “String unit”).

String unit

The string paths are adjusted to one another. In the first path, the tulips go from conveyor 1 to the suspended orientation by means of twisted strings. Then they go to 4 string paths of each approx. 30 cm long, in which the tulips are pulled away from one another while hanging from the bulb. In the string unit, the tulips that were crossing each other on the belt or were in a slanted position, are largely corrected, after which the tulips are suspended in a straight position. In the last path, the tulips gradually stop swinging until they are stable, after which they enter the twist belts of the debulbing section. By using the string unit, harvesting labour is reduced: the tulips can be placed less neatly on the supply belt (entangled roots do have to be loosened).  The string path is fully disconnected from the technology. It contains no bearings etc., meaning that no failures can occur in this path. Selected material is mainly stainless steel.

Debulbing section

In the final string path, the height is determined at which the bulb will be sawn off. This is done by means of twisting clamp belts between which the stems of the tulips are being clamped and an approx. 50 cm conveyor supporting the tulips. By means of the twisting clamp belts, the tulips are returned from the suspended position to the lying orientation and then debulbed by means of the Havatec jack system.

Defoliating unit

The debulbers are made with a deleafer unit that removes excess leaves even better.

Conveyor

This conveyor consists one piece and runs from the string unit to the newly to be delivered transition conveyor. The greatest benefit is that the tulips are continuously held during debulbing, deleafing and synchronisation, strongly reducing the probability of an unwanted slanted orientation.
