Abstract

The present invention provides a specific gravity separator used in a pretreatment process in a process for converting wastes such as food and food residues discharged from large restaurants into resources. Waste food brought in the process for converting waste food into a resource is crushed while passing through a primary sorting crusher (110) from a storage hopper (100). In this case, in order to discharge selectively separated primary impurities (170), or to selectively separate secondary impurities (160) from the waste food such as residues and bones that are primarily crushed in the primary sorting crusher (110), the waste food is crushed again more finely with a secondary fine crusher (120) and transferred to a specific gravity separator (130) of the present invention. The waste food transferred to the specific gravity separator (130) of the present invention is sorted according to specific gravity into light, medium, and heavy specific gravities, and separated into light weight impurities, waste food, and heavy specific gravity impurities. The waste food is transported to a resource facility (140), and light specific gravity impurities and heavy specific gravity impurities are regarded as secondary impurities (160) dehydrated by an impurity dehydrator (150) and discharged together with the primary impurities (170).
