Aspirators, Separators & Destoners
The Perry In-line Aspirator Pre-Cleaner removes dust, chaff, husks, awns and material lighter than the grain to help improve the quality of a product before it is dried. Three capacities are available: 30tph, 60tph (to achieve 120tph two 60tph models can be used in tandem) and 150tph.
Grain is internally spread over the full width of the chamber and the air is pulled through the cascading grain to remove the light dust and chaff. The rate of airflow can be adjusted to suit a variety of crops with an adjustable slide using the chain wheel at the side of the cleaner. Perry also manufacture a full range of exhaust ducting and cyclones to collect the rubbish removed.
Key Points
- Capacities up to 150tph.
- Ideal for removal of light dust & chaff and excellent at improving the bulk density of light crop samples.
- Fan can be situated on cyclone so the exhaust ducting is under negative pressure to minimise dust leaks.
- Comes complete with four fitted mounting brackets.
- All galvanised construction for outdoor use.
- Three separately adjustable cleaning sections.
- Triple extraction point for three times the performance.
- 500mm diameter clip together exhaust ducting.
- Fully adjustable internal guides to ensure the best performance on every crop.
- Side viewing panels to see the effect of adjustments.
- Air control by variable speed drive.
Separators
A separating machine is used to separate different size grains. There are two sieves inside the machine, both with different size holes, which move horizontally back and forth. The first sieve takes out the biggest grains, letting the rest fall through. The second sieve has slightly smaller holes, taking out the medium size grain, leaving you with small grain in the bottom section.
Destoners
Destoners are used after the grain goes through the separator – grain is separated from stones and other light dust and chaff. Air is sucked up through the machine, via a fan in the top, taking out light impurities. The grain and stone that is left vibrates along an angled sieve. The heavier stones are lifted up and out along the sieve, good grain travels down the sieve.
