The invention provides in as improved pressure-baking apparatus for
producing puffed crackers from a starch-containing cereal or other food
material, thereby allowing better control of expansion resp. product
consistency for an enlarged range of crackers types materials and shapes.
Accordingly, the apparatus has a baking mold comprises the combination of
a fixed upper die plate (1,2), a lower punch plate (3,4) directly driven
and supported by a cylinder/piston unit (10), and there between a
peripheral mold plate (6) comprising die holes (7) in registry with said
upper dies (2) and lower punches (4), said peripheral plate being
selectively movable in the vertical direction between said fixed upper
die plate and driven lower punch plate. An hydraulic power system (11,17)
integral with the apparatus is linked with drive unit (10).
