Abstract:
1. A control method for the air-conditioned treatment of products through a treatment process, the method comprising the steps of: (a) measuring a characteristic temperature of the product cyclically at definable time intervals; (b) adjusting at least one environmental parameter in a treatment chamber according to the measured characteristic temperature; (c) measuring in each cycle actual values for the characteristic temperature of the product, the temperature of the air inside the treatment chamber, the temperature of feed air entering the treatment chamber, and the moisture content of the product; (d) defining a desired final state of the product by way of characteristic parameters, the desired final state being defined at least at the beginning the treatment process; (e) determining set values for the measured parameters of step (c) for a next cycle, the set values being determined from the measured parameters of step (c) and the defined parameters of step (d) for the next cycle, the set values being defined automatically; (f) comparing the set values with respective actual values in the next measuring cycle; (g) adjusting at least one environmental parameter in the treatment chamber to create the desired final state of the product; and (h) determining if the set values and the actual values in step (f) are equal, wherein if the values are equal then repeating steps (e)-(h) until the desired final state of the set values of the characteristic parameters has been attained.
