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

Thursday, October 11, 2018 by

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.
