Abstract
The invention provides a fryer that can prevent problems such as poorly cooked food when operation of an oil discharge valve is started and cooking oil is discharged, for example, to adjust the liquid level of the cooking oil within an oil vat. The fryer includes oil vats (13) and (14) for containing cooking oil, a burning device (17) for heating the cooking oil within the oil vats, an oil discharge pipe (33) that extends from the bottom of the oil vat and that discharges the cooking oil from a discharge opening at its end into a tank, and an oil discharge valve (35) that is disposed in the oil discharge pipe and that opens and closes the oil discharge pipe. Furthermore, the fryer is provided with a micro switch (47) and a contact piece (48) for detecting the open state of the oil discharge valve, and alarms (55) and (56) for giving a warning in accordance with the results of the detection by the micro switch (47) regarding the open state of the oil discharge valve. When the micro switch (47) detects that the oil discharge valve has continuously remained in an open state and a predetermined time has passed, heating by the burning device (17) is stopped by controls from control devices (60A) and (60B).
