ABSTRACT:
A direct-steamed laboratory minidigester and a method of operating it are disclosed. This unit may be used to predict process parameters, e.g., yield and Kappa number, for operation of commercial direct-steamed digesters. Runs may be made rapidly and with small quantities of wood and chemicals. A plurality of units may be operated in parallel to generate replicate data points for statistical analyses or operated simultaneously, each under different conditions, to screen process variables, e.g., chemical charge, wood furnish, pressure, temperature, steam rate, and cooking time.
