FIELD: separation of agricultural products at insignificant difference in density. SUBSTANCE: device includes inclined transportation passage with gastight bottom and side walls to which fluidized material is supplied and air is supercharged vertically through gastight bottom. Transportation passage may be vibrated vertically at frequency and amplitude at which mixture to be separated attains acceleration of 3 to 12 g (about 29-118 m/sq.s). EFFECT: enhanced efficiency. 29, 12 dwg
