This cooperation processes the onions and other agricultural products of various growers on this island. Most of the onions are intended for the larger supermarket chains in Finland.
Internal quality
Increasing problems with the internal quality combined with tightened quality demands from retail were the motivation for this company to immerse itself in the various techniques and suppliers. After various visits and comparison tests the choice was made to pick Longobardi. The reliable and consistently working patented NIR (Close Infra Red) system for the internal quality is especially important to Ålands Trädgardshall and means that they can once again meet the retail's high quality demands.
7.5 tonnes per hour
The two tracked sorting machine has 7 exits in total, with box fillers, pre-sorting and two exits linked directly to storage bunkers for the small packaging department. The total capacity is around 7.5 tonnes of onions per hour. The entire machine has been placed on a raised frame to provide optimal function of the box fillers and simpler cleaning of the machine and the working floor under the machine. The machine foresees the standard washing and drying installation for the cups, so that they stay optimally clean. Dirty cups have an influence on the reading of the cameras for the external quality and this means regular automatic washing and drying is of great importance.

To make the installation function optimally it is also important that as much dust and skin is sucked off. In general an onion processing space will be filled with dust and skins and they have a negative effect on the working of the various cameras as well as on the life span of the machine. Together with the firm Modesta from Putten Longobradi realised a complete system on this machine, in which not only is the dust and skin sucked off at different points, the cups are also blow dried after washing using the existing air streams. There is also an overpressure system on all camera systems and electric switch boxes so that the negative effect of dust is also avoided as much as possible here.
The installation on Åland has now been running to the full satisfaction of the customer for a few months now and is therefore the most recent company, following Norway, Switzerland, Sweden, Denmark, USA, England in which the Longobardi optical onion sorting machine Manriba with internal and external quality sorting has been applied with success. The Netherlands is going to be the next country.
