In the preparation of oilseeds for oil extraction, the seed needs to be cleaned and then conditioned to the correct temperature and moisture. The hull is often removed from the seed to increase the protein content of the meal. Chemsta Aspirator is designed to remove loose hulls and foreign material and to heat or cool the seed.

The seed, whole or cracked, enters the aspirator through a rotary feeder. The seed cascades through the aspirator impact rods, splitting and distributing the product flow. This allows the air to pass upward through the falling seed and loosen and remove the hulls. The air traveling through the aspirator is recycled to separate the hulls and dust from the air.

The ChemSta Aspirator uses a closed or recycled air loop, allowing the humidity and temperature of the air to be easily maintained. This results in good drying and conditioning, and it reduces the amount of air exhausted to the atmosphere.

ChemSta Aspirator is mainly used for cleaning particulate matter in industries such as grain storage, flour, feed processing, grease, food, brewing and so on. The machine can separate low density impurities from particulate matter (such as wheat, barley, rice, oil, corn, etc.).
The machine adopts the form of closed-circuit circulating air, which has the function of dust removal and dust reduction. This saves other dedusting equipment and does not exchange gas with the outside world. The machine has the characteristics of small area, simple structure, good separation effect, stable performance and long service life.
