An apparatus for fragmenting a block of frozen vegetable tissue such as peat moss, without causing wide-spread damage to the individual vegetable fibers, comprising a pair of planar jaw members movable between opened and closed positions. Each jaw member has a grating-like configuration defining a plurality of discharge apertures in a spaced apart relationship and also comprises projecting crushing teeth. In the closed position, the jaw members are in a mating relationship, whereby the crushing teeth of each jaw member deeply penetrate the discharge apertures of the opposite jaw member. In operation, a block of frozen vegetable tissue is loaded between the jaw members while they are in the opened position. The jaw members are closed for bursting into fragments the block of frozen vegetable tissue under the effect of multiple pressure points created by the crushing teeth on the block surface and for expelling the fragments through the discharge apertures. The invention also relates to a novel method for fragmenting a block of frozen vegetable tissue without causing wide-spread damage to the individual vegetable fibers.
