Abstract

Изобретение относится к способу фильтрации, в котором материал, подлежащий фильтрации, приводят в контакт с фильтрующей поверхностью фильтрующей среды, расположенной в вакуумной сушилке, и на фильтрующей поверхности фильтрующей среды формируют фильтрационную лепешку и фильтрационную лепешку подвергают процессу сушки, состоящему по меньшей мере из одной стадии, перед удалением фильтрационной лепешки с фильтрующей поверхности фильтрующей среды. Согласно изобретению в процессе сушки фильтрационной лепешки выполняют по меньшей мере одну стадию (12, 22, 32, 42) сушки, во время которой предотвращают прохождение газа через фильтрующую среду и по меньшей мере одну стадию (13, 23, 33, 44) сушки, во время которой газ проходит через фильтрующую среду.Международная заявка была опубликована вместе с отчетом о международном поиске.
