Key benefits

High sanitation standards

All the machine parts touching the product can be easily accessed and cleaned via the maintenance flap on the front of the machine. A barrier between the inlet and sieving box prevents dust from escaping from the machine.

Choose from different configurations

You can order an optional inlet aspiration and optional permanent magnet in the outlet of the first grade product. With the inlet aspiration unit, wear and dust accumulations on the screen are reduced. The magnet helps to clean the grain more efficiently.

Small footprint to fit into new and existing plants

The GrainPlus screening machine is very compact, making it easy to install it in new or existing plants.

Highlight features

Options and configurations

Configure the GrainPlus to fit your product and your plant

The GrainPlus screening machine comes with various options. You can add an inlet aspiration and a magnet to increase cleaning effectiveness. You can also add a dedusting system and choose from a wide range of screen perforations.

Top sanitation

Designed for simple and fast cleaning

A rubber ball cleaning system cleans the sieves while the machine is in operation. Moreover, the GrainPlus features an enclosed design and uses an exhaust air system. These characteristics all add up to achieve a high standard of sanitation and reduces the need for manual cleaning.

Rugged design

Reduced vibration and longer machine lifetime

The GrainPlus screening machine's free running sieve box is mounted on polyamide rods. This construction reduces dynamic loads on the frame and prevents vibrations, thereby prolonging the machine’s lifetime. You can also use the screening machine in multilevel buildings or on platforms.

We use the GrainPlus for the cleaning and processing of malt. The machine works very efficiently and runs without any problems, saving valuable time and money.

The 2 sieves, both with a depth of 0.75 m, are kept in place by the pressure of the front sieve flaps. As there are no screws, the sieves can be changed quickly and easily.
