Sigma

Sigma pre-cleaners are excellent for cleaning performance and removal of up to 90 % of all mycotoxins from the surface of your grain – all in a space-saving, vibration-free package.

The DAMAS SIGMA is a high-capacity pre-cleaning machine for small-sized to large grains or cereals. The DAMAS SIGMA is designed for pre-cleaning, malting barley grading, intervention standard cleaning, as well as industrial cleaning of cereals.

The DAMAS SIGMA takes up very little space and can easily be built into existing plants. The DAMAS SIGMA requires very little foundation because of its vibration-free construction, making it suitable for mobile installation.

Your direct benefits with Damas Sigma cleaner

Removing mycotoxines with Damas SIGMA cleaner

DAMAS SIGMA cleaner is great because seed and grains are cleaned centrifugally by being forced against the rotating screens, each individual grain will be polished and cleaned across its entire surface area. This process reduces the presence of germs, fungi and bacteria by up to 90 % – giving you a much more hygienic end product (proven by the independent German Test institute IFF).

Space saver

We know how precious space can be in a production facility. So we designed the DAMAS SIGMA cleaner to be as compact as possible. In fact, the DAMAS SIGMA will take up half the space of comparable machines – in some cases as little as a third. The compactness of this cleaner also means that you can install it easily in a pre-existing production facility where lack of space can be an issue.

Damas SIGMA cleaner - zero vibrations

With all internal moving parts perfectly balanced, the DAMAS SIGMA gives off hardly any vibrations at all. This reduces the stress on the floor construction and makes it possible for you to place the DAMAS SIGMA high up in steel constructions – or to use it in a mobile production facility.

Humid material welcome

Where flatbed cleaners give up, the DAMAS SIGMA carries on. It will easily clean even very wet grain without losing significant capacity – and without needing excessive screen cleaning afterwards.

Rapeseed specialist

Rapeseed is small and very high in oil content – and as such a challenge for any cleaning machine. Not for the SIGMA. It is capable of cleaning rapeseed to industrial quality without a prior drying cycle. Another benefit of this is that the screens will stay dry and will constantly deliver high quality cleaning performance.

Fast screen change

Because the DAMAS SIGMA cleaner is designed with vertical screens that are removed from the top, no extra floor space is needed when changing or cleaning screens. The design of the machine means that one person can easily handle, change and clean the screens in a very short time.

Damas SIGMA cleaner - Amazing for maize

The Damas SIGMA’s capability if handling very wet material is a strong advantage when cleaning maize – in fact, maize with up to 60 % moisture content can be handled by the machine.

Dust-free working space

As the machine is totally enclosed, you can expect a dust-free working environment – and lower noise levels, too.

Damas Sigma cleaner keeps itself clean

The rotation of the internal components of the machine – combined with the self-adjusting roller brushes on the screens – create a substantial self-cleaning effect. In most cases, it will not be necessary to clean the machine when changing materials. Not even after having used the machine to clean maize with a very high moisture content of up to 50 %.

Double-crop function

As an option, the DAMAS SIGMA can be delivered with a two-crop function making change-over from one crop to another easy and quick.

Deculming while cleaning

When cleaning malted grain, it will automatically deculm the grains in the process, saving you additional equipment and production.
