FIELD: food industry.

SUBSTANCE: group of invention relates to equipment used in the brewing industry, in particular, for the malt mashing process. Filtering apparatus comprises a container having upper and lower sections, first section (13) and second filter section (14) comprising first group of filter members (2), located in the first position near the lower section of the container, comprising second group of filter members (3), located in the first position near the upper section of the container, piping system providing pipelined fluid communication between the filter sections and between a filter section and said filter section's corresponding group of filter members, and circulation means, such as a pump, configured for passing fluid in forward flow (8) and/or in reverse flow (9) between the filter sections. Filtering apparatus is used for extraction of compounds from solid phase using the fluid phase, and also used as a fermenter. Method of mixing a compound of solid and fluid phases, and extracting fluid from the compound is performed using filtering apparatus, in which the first section of the filter and the second section of the filter are located in the container with upper and lower sections, vertically displaced relative to each other, and comprises drawing fluid from the compound into a piping system through a first group of filtered openings located adjacent a first position near the lower section, guiding the fluid via the piping system to a second position near the upper section, delivering the fluid to the compound through a second group of filtered openings in said piping system, located adjacent said second position in the compound, or through one or more non-filtered second outlet openings of the piping system located adjacent said second position in the compound, and extracting fluid from the piping system.

EFFECT: declared group of inventions provides higher quality of products during brewing process due to avoiding various clarification and taste affecting additives; reduced time of the process of the product manufacturing due to avoiding blocking of filters and reduced time for their cleaning.
