Machine to pulp tomatoes etc. - in the nip between perforated drum and elastomer covered pressure drum (PT 14.1.81)

摘要

Machine for reducing tomatoes etc. to a pulp of tiny pieces, is described. The machine comprises two cylindrical drums rotated on parallel axes which are inclined to the vertical and set so that their circumferences form an inward nip into which material can be fed. One of the drums has perforations through which the other drum presses the material which is thus broken down into a pulp discharged into the drum interior. The pulp is discharged at the lower end of the drum. A feed hopper gravity loads material into the nip line between the drums and is sealed against the drum surfaces to prevent leakage. Material not pulpable between the drums, e.g.tomato skins, is discharged separately on the outlet side of the nip. The perforations in the pulp reception drum are pref. larger in cross-section at the circumference than at the interior. The pressing drum is pref. covered with a generous layer of elastomer. Used in pulping tomatoes and similar soft fruit or vegetables. Tomatoes can be pulped without pre-peeling. As the hopper is loaded higher with tomatoes, a greater area of the drums is automatically brought into use. The machine is simple and robust and easy to keep clean. Waste prod. is reduced to a min. to obtain max. yield.
