Grain brush Astréïa
The essential tool upstream of the mill.
The brush makes it possible to obtain a grain
ready to grind.
We have designed this grain brush that we manufacture in our workshops our Astréïa grain brush.
Simple settings, integrated suction provided by an industrial-grade centrifugal fan. It is quite possible to adjust the space between the grid and the brush for optimum quality.
The Astréïa grain brush removes all residues, but also dust and of course insect eggs...
Operation of the
Grain brush Astréïa
Two Nylon bristle brushes brush the grain against a cylindrical perforated sheet
made of high strength steel.
The mechanical cleaning action is threefold:
1) the bristles brush the grain
2) the grain is rubbed against the perforated sheet
3) the grains rub against each other The grain advances in the cylinder pushed by scrapers.
At the outlet of the cylinder, the grain passes into a densimetric column (optional); it is here that the light fractions (straws, bales, leaves...) which have not passed through the perforated sheet are separated from the grain

ELIMINATION
In a single pass, up to 80% less dust and mycotoxins are eliminated without altering the grain.
ELECTRICITY & SECURITY
Electrical box with thermal protection for each motor and built-in ammeter for easy adjustment of incoming grain flow
Electrical power: 2.8kW (brush: 2.2kW and suction: 0.55kW)
A safety switch cuts off the power and prevents the brush from starting if the cover of the box remains open
Three-phase connection by 16A 3P+T socket. Brush delivered with 5 m of cable
The machine must imperatively be anchored to the ground for reasons of stability and safety.
SUCTION
Integrated suction provided by a centrifugal fan
Densimetric sorting column allowing the separation of light fractions: straw, wheat husks.
SETTINGS
Adjustment, maintenance and cleaning of the brush very easy thanks to the hinged cover
Fine adjustment of the brushing intensity via precise mechanical adjustment of the incoming grain flow
Adjustable and interchangeable brushes
A timed capacitive sensor allows automatic brush cut-off when the hopper is empty
HOPPER & DEBIT
Grain flow (for wheat) adjustable from 200 to 700 kg/h depending on the desired brushing. The lower the grit rate, the more intensively the grit will be brushed.
Hopper with a capacity of approx. 50 kg of grain (wheat).
WEIGHTS, SIZES, DECIBELS
Weight: about 170 kgs
Overall dimensions (without the cyclone separator): length 120cm x height 195cm x width 71cm
Noise level of the machine in operation: Lp=85dB (A)
The machine must be placed close (<3 m) to an air outlet to the outside, in a closed room, protected from humidity RH%<70%, T°C between 10 and 40°C
All our products are designed on our farm in the Hérault in France, are then designed by our in-house design office, then manufactured by our companions in our without spot cutting.
