Product: Wheat; 0.75 t/m³ (47 ft³); 15 % H20; 3 % impurity
content
Handling: 100,000 t/a (3.7 m bu)
Cleaning quality: from 3 % to 2 % = 1% impurities = 1,000 t/a (37,000 bu)
Benefit calculation
Aeration 1,000 t á 0.80 € / t = 800 Euro
Storage/ 9 month 1,000 t á 1.50 € / t x 9 = 13,500 Euro
Loading 1,000 t á 0.30 € / t = 300 Euro
Other costs 1,000 t á 1.90 € / t = 1,900 Euro
Savings per year: 16,500 Euro

Local intake pit aspiration:
Dust returns to the product flow.
Traders, terminals; e.g. cooperatives, agricultural trade
Central aspiration:
Dust does not return to the product flow.
Processers; e.g. flour mills, food processers
