Pressing meat against hot surface..
 Observe the amount of water
that evaporates when Chef Bell
presses the meat against the
grill
 The meat gets good contact
with the grill, becomes more
compact and the surface of the
meat that is in contact with the
heat source increases
As a result,
the heat transfer rate & water evaporation rate are increased
The Concept of Hyper-X Dryer

4. Ace Environment Pte Ltd4
 Main components consist of
 hot drum
 high temperature resistance
belt
 pressed rollers
 Wet sludge feed between hot
drum & belt
 Allow vapour to escape through
belt
The Concept of Hyper-X Dryer
 Apply forces to press the sludge against the hot drum, accelerating
water evaporation rate from 1.5 to 3 times compared to without
pressing
