This article describes development of sunflower seed alternative technology of dehulling in frozen state. This technology allows to increase degree of seed dehulling and output of whole kernel. The authors have been tasked to give scientific justification of sunflower seeds fines dehulling technology in frozen state. Experimental pilot equipment for cooling seeds to subzero temperatures has been described and constructed. After obtaining a laboratory pattern of fines from sunflower seeds industrial fraction of confectionery variety "Lakomka", its main technological attributes were firstly determined. Then effective technological attributes of studied fraction dehulling, which provides maximum yield of whole and non-destructive kernel on the assumption seed temperature, were determined. It is determined that the highest yield of whole kernel is observed in the range of effective values rotor speeds. Second stage of scientific research was devoted to detection of regularities for seeds to subzero temperatures influence on composition of dehulled fraction and characteristics of dehulling in the range of effective values of dehullerꞌs rotor rotation speed. It has been established that sunflowerꞌs seeds of confectionery cooling before dehulling causes a positive effect on the yield of whole kernel and on its quality. Thus, it was determined effective technological attributes of confectionery seedꞌs fine fraction dehulling, which provide increase in the yield of whole kernel, as well as significantly increase the yield of non-destructive kernel, which is a mandatory requirement for confectionery production.
