Abstract
The utility model provides an automatic temperature controller for drying flue-cured tobacco, which is composed of a fire-leading air channel, an air door, a time-delay alarm, an electric motor, a bridge-typed thermistor detector, a relay, a cam, a ratchet wheel, etc. The utility model is suitable for a flue-cured tobacco baking room which does not use electricity as a heating source. The utility model has the advantages of simple structure, low cost, precise temperature control, etc.
Description
The utility model is a kind of baking of flue-cured tobacco automatic temperature control, belongs to the temperature automation field.
At present, except that adopting electrically heated tobacco flue-curing house, the baking temperature of other thermal source tobacco flue-curing house all is to adopt the mode that temperature detection is reported to the police, Artificial Control is heated to reach the purpose of controlling the baking of flue-cured tobacco temperature, the not only waste of manpower of the mode of this baking flue-cured tobacco, and the flue cured tobacco quality that bakes also can not get guaranteeing.The method of baking temperature is controlled in electrical heating automatically because cost height and a large amount of electric power of needs are therefore also very impracticable.
The purpose of this utility model just provide a kind of easy to use, cheap, save manpower, need not electrically heated baking of flue-cured tobacco automatic temperature control.
