Processing alfalfa seed from natural sources with admixture, grains of other
species and various impurities are removed and clear grain of the basic culture is
obtained. Grain of the basic culture is prepared for sowing machine and quality planting,
germination and sprouting. Alfalfa seed loses during the processing depend on quantity
and type of weed and other impurities of organic and inorganic origin present in the
naturalized seed.
In this paper is given the analyses of the efficiency during natural alfalfa seed
processing of two different purities (B1, B2), processed on the same equipment that
involves gravity table Oliver - 240. As the relevant parameters that define the effects of
alfalfa seed were: clear grain (%), weed and other cultures seed (%), inert matter (%),
quantity of processed seed (kg), time of seed processing (h), active (kWh) and reactive
(kVArh) current consumption, processing output (%), and seed loses (%). Procesom dorade semenske lucerke iz naturalnog semena sa primesama
uklanjaju se sva zrna stranih primesa i razne nečistoće i izdvaja čisto zrno osnovne
kulture koje se priprema u što povoljnije stanje za sejalicu i kvalitetnu setvu, klijanje i
nicanje. Gubici semena lucerke u procesu dorade zavise od vrste i količine korova i
ostalih nečistoća, organskog i neorganskog porekla prisutnih u naturalnom semenu.
U radu je data analiza efikasnosti pri doradi naturalnog semena lucerke dve različite
čistoće (B1, B2) dorađene na istom sistemu mašina za doradu u okviru koga je korišćen
gravitacioni sto Oliver - 240. Kao relevantni parametri koji definišu efekte dorade
semena lucerke bili su: čisto seme (%), seme korova i seme drugih kultura (%), inertne
materije (%), količina dorađenog semena (kg), vreme dorade semena (h), utrošak aktivne
električne energije (kWh) i reaktivne električne energije (kVArh), randman dorade (%) i
gubici semena (%).
