Grain / Cleaning and Storage.Benefit of a pre-cleaning process at intake.

Improve storability and preserve the quality of grain Optimized use of storage space



Prevent blockage of silo outlets by foreign material

Reduce wear and damage to machines and piping

Increased process safety



Prevention of diseases e.g. formation of toxins and contamination



Reduce risk of dust explosions



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
