Photo report of their new young plants sorting line:

Homogeneity key for Bremkens Orchids

Supplying the grower a tray with uniform phalaenopsis young plants. This was the main goal of Bremkens Orchids when deciding to purchase a new sorting line. Four months ago, they installed one from Flier Systems - equipped with a camera from Aris - and they are pleased with the results. "Next to supplying our growers with a tray with more uniform young plants, it also enables us to work more efficiently", says Christian Bremkens, co-owner of the company.

Uniform young plants
Before working with the sorting machine from Flier, Bremkens Orchids used to sort their young plants at an earlier stage. "When leaving the lab, the starting material was directly sorted in five sizes and then transplanted into a plug. Even though they were sorted, each plant grew on their on pace and differences started to show after a couple of weeks. One of the major problems we had to deal with were the small plants in the tray. These plants are often thrown away by the grower as they are too small to pot."

Sorting at a later stage
So, in order to offer growers a more uniform crop, they decided to purchase a sorting machine. They opted for the sorting machine from Flier Systems that is equipped with a camera from Aris. And next to supplying the grower with a more uniform crop, it also increases Bremkens' production volume. "With this machine we sort the plants, which are transplanted in a PP 4.6cm pot, at a later stage; after twelve weeks. This way, the plants will have a better micro climate in the first phase and it enables us to grow more plants per square meter."

How does it work?
So, how does the machine sort the young plants? In this series of photos and videos, the entire process is explained.


After growing in the small pots for 12 weeks, the plants receive their final quality check before they are put on the conveyor belt of the sorting machine.

When the size is determined, the similar-sized plants will be placed in the same line on the belt. At Bremkens, they work with five sizes, having the largest and smallest size as a starting point. The three other sizes in between are calculated.

After being sorted, and when the belt is filled with 60 plants (the amount that fits into a tray), they are transported to the area where they are put in a tray.


This video shows how they are put in a tray.


The tray that they are using is one that has been especially produced for Bremkens by Pöppelman Teku. "We used to put the young plants in a Polystyrene (PS) tray. The disadvantage of using this material is that the roots often stick to it. Then, if they need to be transplanted, the roots and therefore the plant will be damaged by forcing them out of the tray. Interestingly, the roots do not attach to polypropylene (PP)." However, PP is only used for finished size growing pots. So, they got together with Teku and designed a concept that would fit the requirements and machine. "The concepts consist of a pot and a tray. In the first phase the pot is placed in a small tray (x56) and can be easily lifted out of the tray to put it on the conveyor belt. After camera selection they are 'sucked' into a x60 hole PS tray, and as the pot is made of PP, the grower can easily, without damaging the roots, pull the young plant out of the small pot."


On the left Bremkens shows how easy it is to take the plant out of the pot; the pot will remain in the tray. On the right, the pot.


When the trays are filled with the young plants, all trays will be sorted in one line.


When the line is full, a bench can be filled and the plants will remain in the greenhouse for another 6 to 12 weeks before being shipped out to the growers.
