  • Patent number: 7651619
    Abstract: A method and an apparatus for separating dry matter from liquid includes an enclosed separation environment capable of being pressure regulated. Within the enclosed separation environment, a suspension is brought into contact with at least one filter so as to accumulate dry matter on the at least one filter. The filter with the dry matter passes through at least one set of rollers such that liquid is removed from the dry matter on the at least one filter to form a substantially dry filter cake. Thereafter, the substantially dry filter cake is removed from the at least one filter. The above steps are performed in the enclosed separation environment either under vacuum or overpressure. The invention may be used in various fields such as the food industry.
