摘要： An automatic oven cooks or bakes a food product over a timed period of time during which a burner delivers heat to the oven cavity. Thermocouple sensors in the cavity control a modulator which regulates the amount of gas flowing to the burner to maintain a uniform temperature in the oven. A conveyor carries the food product in order to time the baking period.

摘要： A conveyor oven has a modulating gas valve which raises and lowers the thermal output of a burner that heats the oven. A bypass line passes a minimum amount of gas to prevent the burner from completely shutting down during periods while the oven remains above a threshold demand for more heat. Electrical isolation is provided between temperature controlling devices to prevent an electrical feed back which might otherwise prevent a complete shut down of the oven during hazardous conditions.
摘要翻译： 传送炉具有调节气阀，其升高并降低加热炉的燃烧器的热输出。 旁路管路通过最小量的气体，以防止燃烧器在炉子保持高于阈值要求以增加热量的期间完全关闭。 在温度控制装置之间提供电隔离以防止电反馈，否则可能会在危险条件下阻止烘箱完全关闭。
