ABSTRACT:
Method for the extraction of fruit and vegetable pressings and plant raw materials in a closed system. The extraction is effected by simultaneous mechanical and hydrodynamic effects on the materials, the fruit or plant mass being subjected to several extractions in two cyclically alternating modes of fountain-type and turbulent agitation with different intensities with bladed agitator tip speeds in an over-all range of 3 to 25 m/sec. The apparatus disclosed for practicing the method has a closed heat-insulated vessel with internal draining wall, a conical bottom, a cover having a ventilation opening, and an opening for the raw material, with a driving unit mounted on the cover with two driving speeds. The driving unit is a shaft on the lower end of which there is mounted an impeller, the shaft resting on a special bearing supported on a grid of blades rectifying the material flow, an elongated diffuser surrounding the impeller, the impeller together with a suction unit leading to the diffuser being fixed to the bottom of the vessel.
