Patent ID: 8468715

Claim:
A method for forming an engineered wood product, comprising: a. providing a quantity of pulpwood; b. crushing and scrimming the pulpwood to form a mat; c. drying the mat in a first drying step in a first pass dryer; d. measuring the drop in the temperature (“delta temperature” or “ΔT”) sensed on air entering a scrim mat compared to the air exiting the scrim mat, wherein the change in ΔT over a time period defines a rate of change of the delta temperature (“dΔT/dt”); e. removing the mat from the first pass dryer when the rate of change of the delta temperature (dΔT/dt) for the first pass drying step is less than about 3.2 degrees F. in about 30 seconds; f. applying a resin to the mat of step d; g. drying the mat in a second drying step in a second pass dryer; h. measuring the change in the air temperature going into the mat and the air temperature coming out of the mat in the second pass dryer; and, i. removing the mat from the second pass dryer when the air temperature change reaches a set-point of about 3.2 degrees F. (plus or minus 0.5 degrees F.) per minute.
