Fryer

Abstract

A fryer for business use is provided which can prevent degradation of cooking oil, secure a good cooking environment and improve a work efficiency. To this end, the fryer of this invention comprises: a water tank 32, 82 to store water; an oil tank 9, 51 arranged above the water tank to store the cooking oil in contact with the stored water in the water tank; a heater 13, 52 arranged in an oil layer in the oil tank; and an oil delivery pipe 10, 61 through which to draw the cooking oil in the oil layer by a pump 29, 64 and release it onto a bottom of the water tank 32, 82 ; wherein the released cooking oil rises through the water layer and flows into a lower part of the oil layer.

1 . A fryer comprising:
 a water tank to store water;   an oil tank installed above the water tank to store cooking oil in contact with the stored water in the water tank;   a heater arranged in an oil layer in the oil tank; and   a filter water tank having a filter and installed close to the water tank;   wherein impurities such as deep-fried batter balls are drawn along with water into the filter water tank from a water suction pipe inlet at a bottom of the water tank, with the impurities such as deep-fried batter balls left to settle on a bottom of the filter water tank and with water filtered by the filter returned to the water layer from a water supply opening provided in the water tank   
   
   
       2 . A fryer according to  claim 1 ,
 wherein a heat exchange pipe installed in an oil layer below the heater communicates with a heat accumulating unit having its periphery insulated; and   wherein outer air or air heated by the heat accumulating unit is sent between the heat exchange pipe and the heat accumulating unit by a fan to adjust the temperature of the cooking oil.   
   
   
       3 . A fryer according to  claim 1 ,
 wherein an electrostatic dust collecting plate to absorb fine deep-fried batter balls floating in the cooking oil is installed in the oil layer.   
   
   
       4 . A fryer according to  claim 1 ,
 wherein a cover put on a top of the oil tank and opened and closed by a hinge has its interior communicating with a lower part of a water layer in a cleaning tank; and   wherein a gas containing smoke, smell and oil mist produced from an oil surface is drawn by a suction fan and passed through the water layer to remove the smell, smoke and oil mist of gas before being exhausted to the atmosphere through a gas drain pipe.   
   
   
       5 . A fryer according to  claim 1 ,
 wherein a temperature sensor to detect a water temperature in the water tank is installed;   wherein a water tank cooling fan to lower the water temperature in the water tank is installed in a lower part of the water tank; and   wherein the temperature sensor and the water tank cooling fan are operated to adjust the water temperature in the water tank, and thereby adjust the temperature of the low-temperature oil layer below the heater.
