ABSTRACT:
A process for the recuperation, in a form usable by Man, of the proteins present in the sullage of the dairy industry. This process is effected in a number of devices successively including a biological pre-neutralizing tank, in which the alcaline sullage is submitted to acidic fermentation and is freed from sand, a neutralizing reactor for a further acidification of this sullage by depositing natural zoogloea over the divided materials which are within the reactor, a flocculating device for coagulation of the proteins in the sullage in the shape of proteinic flakes under controlled pH conditions, and a floatation device in which the proteins are floated by micro-bubbles and gathered by scraping. A novel combined flocculation and floatation adjuvant is described; it increases the isoelectric pH, so as to decrease consumption of added acid and increase the flocculation pH range. This flocculation-floatation adjuvant comprises an organic co-adjuvant and a mineral co-adjuvant separately injected in the flocculation device. The proteins which are obtained are emulsified through oses. The final product of the process, which may be a powder, may be used inter alia in animal feeding, in the pharmaceutical industry and in the cosmetics industry.
