Abstract
A gas fryer includes a tank for holding cooking oil, a heat pipe located in the middle depth of the tank so that the heat pipe is soaked in the cooking oil, a combustion chamber located at the combustion gas inlet side of the heat pipe, and a flue located at a combustion gas outlet side of the heat pipe. The heat pipe has a sleeve fitted in the inner wall of the heat pipe, and a spirally shaped mixer installed in the heat pipe. The flue also has an introduction system for fresh air, with a blowing nozzle of the fresh air positioned proximate to a narrowed region located about in the middle of the flue along a longitudinal axis, an inlet of fresh air located at a part of the flue, and a passage of fresh air provided along the inner and/or outer wall of the flue.
Claims14
A gas fryer comprising:
- a tank for holding cooking oil,
- a heat pipe located proximate in the middle depth of the tank so that the heat pipe is soaked in the cooking oil,
- a combustion chamber producing combustion gas and located at a combustion gas inlet side of the heat pipe, and
- a flue located at a combustion gas outlet side of the heat pipe, and
- an insulating sleeve covering the inner wall of the end of the heat pipe at the inlet side, the insulating sleeve preventing direct contact of the combustion gas with the inner wall of the heat pipe at the inlet side, and
- an insulating spirally shaped mixer installed in said heat pipe, thereby providing an approximately homogeneous temperature of the heat pipe.
