Abstract: A method and apparatus for mechanically accomplishing riddling of bottled wines contained in shipping cartons by inverting pallet loads of the cartons so the bottles stand on their capped ends, jostling the bottles as by rapid tilting at predetermined intervals and in predetermined directions, and vibrating the cases and the bottles they contain at desired frequency and amplitude and for periods of predetermined duration. The apparatus provides a bed for receiving pallets loaded with stacked cases of bottled wine to be riddled, the bed being supported at its corners on pivot balls liftable from their supporting sockets which, in turn, have resilient supports. Selective tilting of the bed and its cargo is accomplished by inflatable air bags controlled by a timing system.

Abstract: Apparatus for separating and collecting different grades of grape juice from a continuous action, inclined helical screw dejuicer having a plurality of drip pans below the dejuicer barrel formed to convey different grades of grape juice to receiving troughs, at least some of the drip pans being adjustable longitudinally of the dejuicer barrel for selectively varying the nature and quality of the juice collected by each adjustable drip pan. The method contemplates adjusting the quality of each grade in the manner described, making it possible to collect the "first press" clear, uncolored juice pressed from colored grapes so as to be able to make white wine from red grapes.
