ローラ。 It has a temperature setting device that allows an operator to manually set a desired temperature setting value, detects the temperature value inside the dryer using a temperature sensor, and has an ON/OFF controller for driving and controlling the drying heat source. In a temperature controller for drying tobacco, an oscillation circuit that sends out pulses at a constant frequency;
a frequency division counter that divides and counts the pulses from the oscillation circuit; a frequency selection circuit that selects one of two high and low frequencies transmitted from the frequency division counter; A counter that counts frequency pulses, a D/A converter that converts the digital value from the counter into an analog value, an amplifier that inverts and amplifies the analog voltage from the D/A converter, and an output of the amplifier. A comparator 1 that compares with a common potential and resets the frequency division counter, and a comparator that compares the sum of the output of the amplifier and the output of the temperature setter with the common potential and switches the frequency selected by the frequency selection circuit. 2. A temperature controller for drying tobacco, characterized in that it is equipped with an automatic temperature increase setting device comprising:
