An Overview | Terra-Siv
The self-cleaning Terra-Siv is specifically designed to rapidly extract large volumes of loose soil and debris over a very short distance. Designed to either bolt directly onto the intake of any of our second-generation Evolution Separators or used as a stand-alone pre-cleaner.
The main driver for this design is to assist customers dealing with high soil percentages in their crops. Most growers of overwintered carrots and parsnips already use our highly successful Evolution Separator. The Terra-Siv will turbocharge these separators by removing high levels of loose soil and smaller debris. By eliminating this debris beforehand, the separator can operate more effectively, by focusing on larger particles and leaf matter. The versatility of the system provides equal benefits for a wide variety of other crops, such as potatoes, onions, celeriac, and beets. By utilizing the lateral gap adjustment of the two star shafts, it is also possible to remove undersized crop.
How It Works
The crop is supported on the tips of the stars, allowing loose soil to immediately fall between the fingers, while larger particles are drawn down into the valley between the star shafts. We have found that by mis-matching the star shaft speeds and adjusting the height of the second star shaft we can then effectively entrain irregular shaped objects deeper into that valley without pulling the crop through. The key is to eliminate any flex or movement within the shafts and supporting chassis while keeping the star fingers open in the heaviest of soils. This was achieved by stabilising the spacing between the stars. Having uniform star spacings allows us to maintain a very tight tolerance between the cleaning finger and adjacent stars. The use of a square-edged steel finger ensures the gap is repeatedly cleaned, twin roller bearings consistently flex the soft fingers, completing the self-cleaning cycle.
The design is focused on low maintenance and tool-free adjustment. Direct drive electric motor/gearboxes, along with remote greasing, are fitted as standard. For operator ease, all adjustments are made via push button or turnbuckles.
