Summary of Harvey Gjesdal Five-in-one Rotary Seed Cleaner (Evaluation Report - PDF File - 0.52 MB)
Quality of Work: The Gjesdal Five-In-One Rotary seed cleaner was effective in removing contaminants from spring wheat, oats and canola. Certified No. 2 grade was obtainable with acceptable losses in screenings. Certified No. 1 status could be obtained if problems such as ergot in wheat, bosom oats and wild oats in oats, and ball mustard in canola were not present or if other machines were used in conjunction with the Gjesdal machine.
Rate of Work: Capacity of the cleaner varies depending upon the crop, contaminants and grade desired, Best results with the samples tested were obtained with incoming feed rates of 44 bu/h (1.2 t/h) in wheat, 45 bu/h (0.7 t/h) in oats, and 10 bu/h (0.2 t/h) in canola.
Ease of Operation and Adjustment: Adjustment of settings such as scalper drum speed and indent cylinder trough position were easily accomplished. However, changing grader shells or indent cylinders was awkward and time consuming.
Power Requirements: Two electric motors, 3/4 hp (0.56 kW) and 1 hp (0.75 kW) were used.
Operator's Manual: The manual supplied with the test machine provided a good explanation of how the machine functioned and some suggestions of possible settings for various crops. More information concerning service, safety and grader shell and indent cylinder replacement was needed.
Operator Safety: The Gjesdal cleaner was safe to operate if normal safety precautions were observed.
Mechanical History: No durability problems occurred during testing. However, the scalper drive belt required more tension and a very slight wobble developed in the indent cylinders near the end of the test.
