METHOD FOR PRODUCING EXTRACTS Russian patent published in 2017 - IPC A23L19/00 

FIELD: food industry.

SUBSTANCE: operations of defrosting, grinding and extracting frozen fruit and berry raw materials are carried out in the apparatus in the field of low-frequency mechanical vibrations by means of a vibration plate mounted with the possibility of the reciprocating motion in the vertical plane, characterized in that the plate with the thickness of 3 mm has a flange of an equal height, directed upwards and downwards, with the total height of 20 mm, and is perforated with holes of the diameter of 0.0025 m with the free cross-section fraction of 16.5%, carries out reciprocating movements with the frequency of 20 Hz and the amplitude of 8 mm, being at the distance of 45 mm from the apparatus bottom, the cover is mounted airtightly at the distance of 0.015 m from the free liquid surface level in the apparatus, the solid phase in equal proportions is placed in the space above and below the vibration plate, processing the solid phase is carried out at the phase ratio (S/L) = 0.5.

EFFECT: invention allows to increase the concentration of dry water-soluble substances in the final product, to increase the utilisation factor of the apparatus volume and its productivity with smaller amounts of an extractant.
