The present invention provides a deep fryer that has both oil (101) and water (102) layer in contact with each other to enable fried impurities to sink to the water (102) layer. The fried impurities are filtered out using a mesh filter (131) and the water is pumped back into the water layer (102) after filtration. The temperature is fixed at a default setting, 180° C. The thermocouple will be automatically cut off when there is a drastic increase in the temperature of (oil 101) and water (102) layer. Alarm systems notify the user when the deep fryer is not working correctly. The whole fryer shuts down if there is a fault in the (pump 132) or temperature.
