A performance evaluation of a new helical two-sided manure distributor


Although used prevalently in both large conventional and organic farms, modern manure spreaders offer unremarkable outcomes in terms of distribution width and uniformity. A study published in the journal Engineering in Agriculture, Environment and Food seeks to determine the parameters by which the performance of new helical two-sided manure spreaders is to be determined.

  • Modern manure spreaders tend to suffer from a non-uniform application when the moisture concentration of manure increases. The same outcome is observed whenever manure with varying moisture concentrations is used.
  • The researchers focused on a new helical two-sided manure distributor capable of spreading manure at different moisture contents with long distribution width in uniform patterns.
  • Their evaluation involved the following factors: moisture content, forward velocity, and the rotational speed in the drum. This revealed that both moisture content and rotational speed had a significant impact on both distribution width and uniformity.
  • Manure with a moisture content of 23 percent wet basis (w.b.) and 54 percent w.b. and a rotation speed of 1,000 rotations per minute (rpm) could be distributed by the machine at a maximum width of 19.3 m and 23.3 m respectively.

The results indicate that increasing moisture content also increased the manure distribution uniformity.
