Sparter

    Sparter is one of a kind and gives growers the following benefits:
  • Better quality asparagus due to a patented underground detection system. This means that the asparagus is harvested before emerging from the soil, so avoiding violet discoloration and reducing the number of open heads.
  • With subsurface detection, the harvesting frequency can be reduced to 1x/3 days, thus tripling the harvesting capacity compared to a system with detection upon surfacing.
  • Higher yields through fewer losses on account of underground detection. This lessens the chance of underground damage compared to hand-picking.
  • Higher yields through improved quality because the asparagus harvester restores the sand bed after picking, so reducing the percentage of bent spears.
  • Underground detection does not require a light source, which means the cultivator can work day and night, as required. This means machine capacity can be increased yet further.

Cerescon has recently expanded its product portfolio with a 1-row self-propelling Sparter. This is the lead model for the market.

    Additional benefits of the 1-row self-propelling Sparter:
  • Capacity: depending on the asparagus variety, weather conditions and harvesting frequency, approx 0.3 ha/hour. During the asparagus season, the 1-row Sparter can cover around 30 ha with a harvesting frequency of once every 2.5 days and 16 hours a day harvesting.
  • This is the equivalent of 25 hand pickers.
  • Speed control for optimum use of 2 harvesting robot per row.
  • Easily transportable by road using a trailer.
  • Small turning circle due to compact dimensions. This machine can negotiate a 6-metre headland turn.
  • Caterpillar tracks for reducing soil compaction and extra stability.
  • A lower investment for growers, but still a reasonable payback time.
  • This machine can be driven by one operator; no tractor is needed.
  • The 1-row self-propelling Sparter can be adapted for use with mini-tunnels.

The Sparter can be supplied in 3-row, 2-row or 1-row versions. For the 2020 and 2021 seasons, only the 1-row self-propelling version will be available.

Harvesting with the Sparter demands a number of requirements on the part of your sand beds. Download the specifications for the sand beds

Because situations vary from grower to grower, investment payback times can differ. On average, the costs of harvesting by machine can halve those of hand-picking. Cerescon will be happy to help calculate the payback time for individual situations. Interested? If so, submit your contact details using the Contact form, adding the subject-heading “Payback calculation” and the name of your company. Cerescon will get back to you within 7 days to request more detailed information. We will send you our calculation within just a few days.

Detection detail

Detection
Cerescon has a unique patented detection method: advanced proximity sensors are able to detect the asparagus underground without coming into contact with the asparagus. A rapid retraction mechanism prevents contact with the asparagus so that it remains undamaged. At this point, the coordinates of the asparagus are transmitted to a harvesting robot.

Cutting detail

Picking
The patented harvesting robot (2 per row) picks the asparagus from the top of the bed in one single movement and places it on a conveyor. The tractor pulling the machine drives at a constant speed so optimising machine capacity. The conveyor transports the asparagus to a collection unit. An operator sits at the rear of the machine to transfer the asparagus from the collection unit into storage crates.

Recovery detail

Sand bed repair
The hole that is left behind in the sand bed is repaired by the sand bed repair module which ensures that the sand bed remains fully homogenous throughout the season. Sparter removes the plastic film from the sand bed in front of the machine and puts it back into place after picking.
