Topping Machine

Van Dijke’s Topping Machine: for an amazing cutting result. For the back- and bed cultivation of your bulbous plants, Van Dijke has topping machines with different sizes.

How does the Topping Machine work?

The machine is driven by a hydraulic motor and has a lifting mast to montage it to a tractor. These has two cylinders: one cylinder gives a perfect adjustment in the topping height. The second cylinder, the correction cylinder, makes sure that the topping machine is completely sideways adjustable. The diagonally polished cage construction with adjustable leveling results in a wound-friendly cutting of the plants. These are barely places to the under-knife and that results in less snaps. This also makes it possible to drive quickly through the plants. This results in an optimal cutting result with big topping capacity. Also with bed cultivation the flowers are exported to both sides of the path by the use of a mortar.

Cascade Washer

Van Dijke’s Cascade Washer is used all over the world and is known as the best way to clean and wash your products! The power of this machine comes from the use of a very high water flow rate to achieve a perfect seperation of stones, rocks, lumps and other dirt from your product. The machine is smart-designed which means that almost all driven parts are above water level. All important parts of the system are easy to reach which makes this a very maintenance friendly machine.

How does the cascade washer work?

The washer is made of two parts, an receiving hopper and a settling tank. The products, like potatoes, carrots of other root vegetables, are brought into the hopper and will float. Because of the water flow, the rocks and clods will sink to the bottom and will settle down on the discharge conveyer. Then the water flow takes the products out of the funnel into the settling tank. In this tank, the remaining soil and sand will be separated and discharged through a valve.

The key features of the cascade washer:

Galvanized of stainless steel options.
Including adjustable water level for the best washing result.
Extremely low water consumption
The products are threated gently to prevent damage.
Including an adjustable seperation process
Available in several sizes and capacities.

Aqua Grader

Van Dijke’s Aqua Grader sorts flower bulbs innovatively and exclusively! The Aqua Grader is very suitable for washing (lily)bulbs, shortening the roots and separating the (lily)bulbs in deliverable goods, sapling and residual roots.

How does the Aqua Grader work?

The (lily)bulbs are flushed in a rinse funnel, where they will end up on a roller sieve with the washing water. The sieve cuts the root residues from the bulbs with knives, which results in better processing. Then the (lily)bulbs are cleaned by using a brittle set and will leave the machine.

Aqua Grader 2.0

The first Aqua Grader was launched in 2006 and since then a lot of small changes have been made. After an unique collaboration between users, engineers and service engineers, they concluded that t total redesign was required. In 2016 two prototypes were built, after a long, intensive period. These two are successfully tested and finished. That was the start of the Aqua Grader 2.0!

This Aqua Grader is made in a way that makes maintenance very easy and that is unique for this machine. The most important aspect is that the vibrators of the sieves are placed on top. This makes maintenance and montage much easier but gives also the unique possibility to get an essential better vibration image. That is because they are places in the middle of the sieve bed. You can also adjust the vibration bed very easy which gives a the perfect finetuning.

Also there has been a lot of attention for the technic. There are bigger RVS bearings placed in the sorting rolls, which gives a higher quality and longer service time. Also there has been extra attention for making the machine leak proof. The older generations were known of leaking a lot of water. Now the RVS chute continues above the roller bed which limits leakage to a minimum.

The Aqua Grader is in 3 models available: the S1, S2 and S3 (with resp. 1, 2 and 3 sieves). Because of the modular built-op, there is a possibility to expand the Aqua Grader with more sieve units.

The result of the use of the Aqua Grader:

20% less time is needed for processing the same quantity of bulbs
25% to 30% less manpower is needed for processing the bulbs
Depending on the product, you need 20% less storage capacity.
The capacity of the Aqua Grader is, depending on the sort of (lily)bulbs, 1 to 1,5 ha per day (with 8 working hours in a day)
The transport costs are 20% to 25% lower
The end product is visually cleaner
