DEFINITION

Classification: 34/389

Adding of nondrying treating substance:

(under subclass 380) Process wherein a non-chemically reactive substance is added to the treated material where the added substance does not promote the removal of moisture from the treated material but does affect the physical nature of the treated material or the manner in which the drying operation is carried out.

(1) Note. Some examples of the addition of nondrying treating substances could be the addition of saturated steam added to a wood drying process to encourage uniform drying of the wood, the addition of an inert gas to a drying process for the purpose of preventing combustion of the treated material, addition of a fabric softener to the drying process for clothes, etc.
