Gruber grain cleaning
Grain cleaning
Windsifter grain precleaner 20-30 T/H
The Gruber Grain Precleaner GR Series, is used for powerful pre-cleaning of grain, maize and other grain crops from dust, chaff and other light foreign matter. It eliminates up to 85% of the foreign matter in the grain. This means faster and more even drying of the grain as well as an improvement in the quality of the stored goods. These grain precleaners work according to the air classifier principle and are suitable for separating those parts that are lighter than grain (e.g. dust, husks, small grains, etc.). The air classifier fan can be adjusted to the required air output, which depends on the type of grain, among other things. The air flow separates the lighter parts in the cleaning cone and thus ensures a good cleaning effect.
- Windsifter precleaner GR 20 (max. 20 to/h)
- Windsifter precleaner GR 30 (max. 30 to/h)
With the Gruber sieve tube cleaner, the grain or maize kernels are rolled along a sieve tube. In the process, parts that are smaller than the grains (dust, sand, small stones, soil) are separated and discharged collectively via the jacket pipe. Astonishingly good cleaning results are achieved with this simple grain cleaning. The length of the cleaner is 2 m.
The following diameters are available as standard:
- Sieve tube grain pre-cleaning 100 Ø
- Sieve tube grain pre-cleaning 120 Ø
- Sieve tube grain pre-cleaning 150 Ø
- Sieve tube grain pre-cleaning 200 Ø
Windsifter Industrial Grain Precleaner 40-60 T/H
The Gruber Industrie air classifier grain rings of the GR series are characterised by their particularly stable construction for a long service life in continuous use. They are used for powerful pre-cleaning of the grain, maize and other grain crops from dust, chaff and other light foreign bodies. It eliminates up to 85% of the foreign matter in the grain. This means faster and more even drying of the grain as well as an improvement in the quality of the stored goods. These grain precleaners work according to the air classifier principle and are suitable for separating those parts that are lighter than grain (e.g. dust, husks, small grains, etc.). The air classifier fan can be adjusted to the required air output, which depends on the type of grain, among other things. The air flow separates the lighter parts in the cleaning cone and thus ensures a good cleaning effect.
The following types of Gruber Industrie wind classifier are available:
- Windsifter industrial precleaner GR 40 (max. 40 to/h)
- Windsifter industrial precleaner GR 60 (max. 60 to/h)
Inclined floor Industrial grain precleaner up to 100 T/H
The Gruber inclined floor grain cleaner in industrial design is characterised by its maintenance-free use in continuous operation and at high throughput rates. The inclined floor cleaner works according to the sieve-suction principle: impurities with a lower bulk density than the grain, e.g. Dust, husks, are extracted with the air flow.
Type:
- Gruber inclined floor industrial pre-cleaner GR 100 (max. 60 – 100 to/h)
Commercial Vibrating screen Grain cleaner SVR5, SVR 10
The Gruber vibrating screen grain cleaner can be used for pre-cleaning, intensive cleaning and for calibration or seed cleaning.
Functionality of the Gruber vibrating screen grain cleaner with 2 double screens and suction fan:
The contaminated grain is conveyed to the top grain inlet of the vibrating screen cleaner. The adjustable inlet plates at the grain inlet ensure an even distribution of the product. At the same time, air flows through the grain to remove the lighter dust. The product first enters the upper sieve box in which the sieves, which can be changed depending on the type of grain, are mounted. The upper sieve separates the product from the coarse rejects, the lower sieve separates the good product from the final rejects. The same steps are carried out in the lower sieve box. Before exiting, the good product passes onto one of the two decelerators, a second air stream removes the lighter impurities, which are directed to a cyclone or alternatively a filter.
Mobile grain cleaner combination 7 to 40 T/H
The Gruber Grain Cleaning Combination Type VKR or with increased discharge height VRKE, is suitable for optimal pre-cleaning at the grain intake. The chassis with castors makes the unit easy to operate by one person.
The Gruber VRK / VRKE series of grain precleaners are used for powerful pre-cleaning of grain, maize and other cereals from dust, chaff and other light foreign bodies. It eliminates up to 85% of the foreign matter in the grain. This means a qualitative improvement of the stored goods. These grain precleaners work according to the air classifier principle and are suitable for separating those parts that are lighter than grain (e.g. dust, husks, small grains, etc.). The air classifier fan can be adjusted to the required air output, which depends on the type of grain, among other things. The air flow separates the lighter parts in the cleaning cone and thus ensures a good cleaning effect.
Mobile Hybrid Grain Cleaner Combination 7 to 40 T/H
– this product was awarded the “AGRARFUCHS” as an innovation.
The Gruber grain cleaning combination type VKRH sets new standards in grain pre-cleaning technology: Optimal results are achieved by combining air classifier technology and sieve cleaning: Lighter particles such as dust, chaff and straws are removed by the air classifier. Parts that are not caught by the air classifier due to their higher specific weight, such as sand or small stones, are sorted out by the sieve cleaner.
The mobile grain cleaner VRKH, is suitable for optimal pre-cleaning at grain reception or for grain cleaning before loading. The chassis with castors makes the unit easy to operate by one person.
