DRYIT Semi-Continuous Tray Drier
Practical Action
Lifting Mechanism
The lifting mechanism is the most critical part of the drier. It is mounted on the upper frame
and enables the user to lift all the trays above the bottom one. This tray is then removed and
the user drops the other trays down using the mechanism.

Construction
1.) Link
The two links, which connect the bearing shafts (via cams), are drilled and cut according to
drawing TD 006.
2.) Split Bearings
The split bearings should be made from oil impregnated hardwood. For a circular-bearing
surface it is necessary to drill the large hole after the two halves have been made, see
drawing TD010.
