Benefits in cash – pre-cleaning
Pre-cleaning performed immediately after harvesting allows to:
remove impurities, thus reducing the amount of material for drying – approx. by 5%.
reduce the moisture content of the raw material before drying by approx. 2% (for wheat)
This translates into the savings as specified below:
It has been assumed that lowering the moisture content of 1t of grain by 1% (1 t/%) requires the use of
approx. 2 litres of fuel oil (the cost of electricity and labour has not been taken into account).
raw material – 1 tonne * 4 t/% * 2 litres * 1,00 € = 8,00 €
material after cleaning – 0,95 tonne * 2 t/% * 2 litres * 1,00 € = 3,80 €
In the case of corn, pre-cleaning allows for greater moisture reduction (on average
fractions II and III have a moisture content lower by 4 to 6% compared to the raw material).
This translates into a higher amount of green waste.
Cost of drying:
raw material – – 1 tonne * 16 t/% * 2 litres * 1,00 € = 32,00 €
material after cleaning – 0.9 tonne * 12 t/% * 2 litres * 1,00 € = 21,60 €
Savings – seeds
Separation allows to select the best material for sowing, with similar
For example, in the case of non-separated wheat with a germination capacity
of 96% after 14 days, the germination capacity after 7 days was 80%.
For separated seeds, these values were 96% and 92%, respectively. This translates into
an uniform grain maturation process during the harvesting period.
In the case of standard seeds, at harvest time about 80% of grain was ripe and ready to be
harvested, while the remaining 20% consisted of unripe or overripe ears.
The separation process in this example allowed to achieve approx. 92% of uniform,
ripe ears. This translated directly into a 12% increase in yield and allowed to avoid
natural contamination of the field with spilled grains.
The table below shows the savings achieved with the grain separation process in the analysed example
With our separator for pre-cleaning the harvested grain before drying,
selection of material before sale and the production of seed for your
own use, you can get a return on your investment after just 1 year!
