Treatment of wine lees on an industrial scale. [wine lees processing]

Patent:

Abstract

EtOH and tartaric acid are recovered from wine lees by compressing the lees into pellets, distillation with steam to remove alcohols followed by fractional distillation to recover EtOH, roasting and pulverization of the EtOH-free pellets to coagulate collids, and extraction of the suspension with water and mineral acid to recover tartaric acid. Mother liquors are recirculated through the tartaric acid recovery process and the residual material is dried to a protein product which is useful as fertilizer or as animal feed.
