by conduction, i.e. the heat is conveyed from the heat source, e.g. gas flame, to the materials or objects to be dried by direct contact

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Drying solid materials or objects by processes involving the application of heat > by conduction, i.e. the heat is conveyed from the heat source, e.g. gas flame, to the materials or objects to be dried by direct contact

CPC:

Drying solid materials or objects by processes involving the application of heat (in specific machines or apparatus F26B9/00 - F26B19/00) > by conduction, i.e. the heat is conveyed from the heat source, e.g. gas flame, to the materials or objects to be dried by direct contact

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
