First Claim
Patent Images
1. A method for the early detection of carbonization during a drying process of an organic material, comprising:
- (1) hot-air drying the organic material in a dryer, wherein the hot-air drying produces an exhaust comprising one or more of water (H2O), carbon monoxide (CO), and carbon dioxide (CO2); and
at least one of;
(2) detecting a change in temperature per unit time of the exhaust;
or(3) detecting a concentration of carbon monoxide in the exhaust;
or(4) detecting a concentration of carbon dioxide in the exhaust,determining that carbonization has occurred when the change in temperature per unit time of the exhaust is 0.5°
C./min or more, or when the concentration of carbon monoxide exceeds 2 ppm, or when a change in the concentration of carbon dioxide is 10% or more.

Abstract
The present invention relates to a method for early detection of carbonization during the drying of an organic material. The method of the present invention measures temperature variation per unit time of exhaust gas containing water (H2O), carbon monoxide (CO), or carbon dioxide (CO2), which are to be generated by the pyrolysis of an organic material, and the concentration of carbon monoxide/carbon dioxide of the exhaust gas, so as to determine the occurrence of carbonization therethrough, thereby enabling early detection of carbonization within a dryer.
