This decanter has been designed for extraction products.
Decanters are a very efficient means of carrying out solid-liquid extraction with a high solids content. Before entering the decanter, the extraction product, which has previously been comminuted, broken down or ground down, is mixed intensively with the extraction agent in a separate mixer. The inlet through which the suspension flows into the decanter is arranged axially in relation to the rotating bowl. The solid-wall bowl has a cylindrical section for efficient clarification of the liquid and a conical section for dewatering the solids. The scroll, which rotates with a slight differential speed relative to the bowl, conveys the solids (extraction residue) to the solids discharge at the conical end of the bowl. The extract is conveyed to the cylindrical end of the bowl where it is discharged via a centripetal pump.
GEA clarifiers for pharma extraction are used in solid-liquid extraction processes with low solid contents (up to approx. 7 % by vol.).
GEA separators for pharma extraction are designed in accordance to GMP requirements.
GEA solid-wall disc-type separators are used for liquid-liquid extraction processes
