Machine to strip skin etc. from food prods. e.g. meat, fish - has friction roller cleaned by rotary brush downstream of stripping blade

摘要

The prod. is displaced along the surface of a flat feed plate to meet secantly the circumference of a friction roller. The roller carries the prod. against the cutting edge of a stripping blade which is tangential to the roller. The edge of the blade is parallel and opposed to the delivery edge of the feed plate. The periphery of the friction roller is now cleaned with a stiff-bristled brush as it moves between the blade cutting edge and the edge of the feed plate. Brushing takes place over the full, axial length of the friction roller. Brushing is pref. by means of a roller brush rotating on a longitudinal axis parallel to that of the friction roller. If the friction roller and brush are rotated in the same direction, the bristles meet the friction roller surface travelling in the opposite direction. The linear speed of the bristle tips is pref. greater than the speed at the circumference of the friction roller. Useful for sepn. of skin, rind, tendons, ligaments, muscle tissue etc. from meat, offal, fish, chicken etc. The machine can handle fish and other fragile skins without becoming jammed. The friction roller is cleaned as effectively but more economically than with compressed air jetting.
