DRYIT Semi-Continuous Tray Drier
Practical Action
Construction
1.) Cut, plane and sand wooden members according to drawing TD015. Note:
(i) cutaways are different if corner reinforcements are recessed
(ii) Internal partitions (dividers) are 19mm lower than outside wall
2.) Screw and glue the frame together, using water resistant glue
3.) Place the nylon gauze over the drying compartments and fix in position with the plywood
(exterior grade) sandwich strips and nails
4.) Nail sandwich strips around vent end of tray
5.) Construct a long handled metal hook for tray removal
6.) Drill tray ends and attach a rope removal handle at each end
Cladding and Tray Guides
Exterior grade plywood cladding 12mm thick, is used on the base and drying cabinet to
direct and contain the drying air.
The base and drying cabinet should be painted (no lead paint!) before the cladding is fixed in
position.
The cladding must be measured and cut to size from the completed base and drying cabinet.
Hence the dimensions given in the parts lists are approximate.
1.) Base Cladding
The completed base with cladding is shown in figure 17
