Beschreibung
Zusammenfassung:	A method and apparatus for delivering prepared wet fruit and vegetable particles into centripetal confinement under subatmospheric pressure, contacting the particles with heated edible oil until they have been puffed and dehydrated to a hygroscopic condition, hardening dried particles by cooling with cold oil, centrifugally removing excess oil by rotating trays and discharging the hygroscopic particles into packages to prevent access of moisture during storage and shipment. A multiple unit system comprising pressure vessels that are fitted with a multiplicity of relatively shallow trays is arranged to receive a procession of prepared wet fruit particles and dehydrate and puff the particles to a hygroscopic condition, then to deliver the puffed particles to a packaging machine, to be sealed in moisture barrier packages. The dehydrating vessels with auxillary systems are described.
