FIELD: food-processing industry. SUBSTANCE: method involves producing at least one container with filtering surface diameter exceeding that of air-permeable portion by 1.002 - 230 times; forming filtering surface so that it acquires the shape of spatial enclosure of constant and/or variable curvature or combined configuration with maximum distance between its apex and plane coinciding with at least one nonlinear length of contour of air-permeable portion, or between its apex and plane of horizontal projection of related air-permeable portion, ranging between 0.02 to 78 recited diameters of air-permeable portion. EFFECT: increased efficiency, simplified construction and reduced raw material loss by increased quality and efficiency of aspiration process. 718 cl
