A procedure for the preparation of vegetable pulp destined for juice and puree extraction, and a device for the enacting of the said procedure

摘要

The invention relates to the field of procedures and machines for the extraction of juices and purées from vegetable matter. More precisely, the invention refers to a procedure and a device for the preparation of vegetable pulp destined for the extraction of juices and purées. The procedure subjects the product to be treated to a series of compression stresses in rapid succession, to reduce the product consistency and to increase its tendency to peel from its skin. The device which performs the above procedure comprises two shaped moving walls (1,2) describing internally a cavity (11) inside of which the product to be treated flows. The procedure and the device offer excellent pulp treatment results while avoiding the necessity of heating the said pulp before separation between purée and scrap.
