‘Heat pockets’ inside the stacks are to be
avoided. It is therefore essential that gaps
should be left between the large cases
when stacking.

5. Slide 5
Stacking sequence during storage
Wrong!
The air is
reverted in
front of the
stack.

6. Slide 6
Stacking sequence during storage

Air flowing through
the stacked rows.

7. Slide 7
Proper stacking during loading
Foil
If there are not yet enough
vegetables available to form a
continuous stacking line under the
evaporator, empty cases, covered
with sheeting, may be used to fill
the gaps.

8. Slide 8
Incorrect unloading
door
There is no airflow
through the stacked rows.
Result: heat pockets.

9. Slide 9
Correct unloading
door
Unloading should start on the
side opposite the evaporator.
Stacks must be continuous in
the blow direction of the
ventilator, otherwise the air is
reverted and pockets of heat
form amongst the remaining
vegetables.
