Methods and apparatus for producing pieces of sweetened, dried fruit.
Methods as described in the present disclosure generally include
supercooling sweetened, dried fruit having a moisture content between 8%
and 18%, and then breaking the supercooled fruit into pieces having an
appropriate size distribution. Supercooling the fruit may be accomplished
by immersing or otherwise exposing the fruit to a supercooling substance
such as liquid nitrogen, liquid oxygen, or solid carbon dioxide. Breaking
the fruit may be accomplished, for example, by rapidly vibrating the
supercooled fruit on a screen, or by passing the supercooled fruit
through a cutting device such as a centrifugal slicer, among others. A
system for producing pieces of sweetened, dried fruit may include
apparatus for drying the fruit, infusing it with sugar or otherwise
sweetening it, immersing or otherwise exposing the fruit to a supercooled
substance, and/or breaking the fruit through vibration, cutting, or the
like.
